Homemade pipe bender for profile pipes: application, drawings, video. We make a pipe bender for a profile pipe according to the drawings Do-it-yourself pipe bender for a profile pipe

Quite often, in the manufacture of greenhouses, greenhouses, arches, fences, shower cabins, metal frame furniture and other structures, cold-rolled profile pipes are used that need to be bent. This problem can be solved with the help of a special pipe bender, which will do a good job of creating pipe bends. However, not everyone will be able to purchase a factory version of such a tool. Therefore, home craftsmen, and many professionals, make pipe benders with their own hands. To do this, you need to use the tips, study the design drawing and watch the video instructions.

Pipe benders - design and types

If to make a structure it is necessary to bend a profile pipe along a radius, then a pipe bender can easily cope with this, with which you can make a bend up to an angle of 180 degrees. This the device is capable of changing the configuration of pipes made of stainless steel, metal-plastic, aluminum. In this case, the bending is carried out according to the required dimensions and shape.

Pipe bender design

The design of such a tool depends on its type. However mandatory elements are:

On top of the main part of the machine there can be a level check and a plug for filling the oil. Installation strips are screwed onto the threaded part of the tool, which are welded structure. The bottom bar is secured with a locking nut, and the top bar is pressed with two screws and a lock.

To install supports, special holes are provided on the transverse plates of the device. Bottom of pipe bender There are threaded holes for installation bolts, which are height adjustable.

The bent pipe on such a structure is located on a stream, which is located in the middle of its stop. The bending segments must be made of precision cast steel.

Today, thin-walled profile pipes with thin walls are increasingly used for the manufacture of various structures. That's why structural drawing The pipe bender for such workpieces is somewhat different. To prevent deformation of the pipe when bending it cross section, profile rollers should be selected with the same cross-section as the product.

Types of pipe benders

Commercially available professional pipe benders can be manual, electric or hydraulic driven.

Wherein Electromechanical tools are considered the most convenient, with the help of which the most accurate radius and bending angle can be ensured. The use of such a pipe bender does not entail any deformation of the profile.

The manual drive design is used for bending small diameter pipes.

Hydraulically driven pipe benders are capable of bending workpieces that can be up to three inches in diameter. Therefore, such a tool is designed to perform large-scale work.

In addition, pipe benders may vary by the method of exposure to the product, with which it will be curved. These methods include:

1. The crossbow method, in which the pipe rests on two stationary rollers and bends between stops under the influence of a template located on the rod.
2. Winding - with this method of bending, the workpiece first attaches itself to the roller of the structure. Then a stop is placed at the bending point. The roller begins to rotate and wind the pipe between itself and the stop. In this case, the template and the product are movable.
3. Break-in is the most in a simple way pipe bending. On such a device the template is motionless. The pipe is simply clamped and the pressure roller moves and bends the pipe around the template.
4. The rolling or rolling method involves the use of three rotating rollers. One of them is central, and two are supporting. The central roller presses on the workpiece, so it must be installed relative to the supporting elements in accordance with the required radius of the product.

When bending pipes using the first three methods, the bending radius is set by a template. In addition, with the crossbow method, everything pressure from the rod is transferred to the workpiece at the top point of the template where the metal is most susceptible to tension. Therefore, thin-walled products in this place may lose their shape or even break.

The rolling method has virtually no disadvantages. It is by rolling that steel bends are manufactured in the factory. Using the same method, it is much easier and more efficient to bend profile pipes.

DIY pipe bender: drawing, video instructions

Homemade pipe benders can be made in various variations. Even the simplest of them can provide a bending radius. The pipes on them are bent using a template.

The simplest template pipe bender

Template for such a design made by hand from wooden boards , the thickness of which should be slightly larger than the diameter of the pipes being bent.

The boards are cut with a slight slope, which allows the workpiece not to slip. The boards are attached to each other and to the base in any convenient way.

Besides the same reason a stop must be attached next to the template, into which the workpiece will rest when bent. The distance between it and the template should be such that the pipe can be easily inserted into this gap.

The pipe bender is ready and can now be used for its intended purpose. To do this you need:

1. Insert one end of the workpiece between the stop and the template.
2. Grab the opposite end of the pipe and bend it according to the template using gentle, smooth movements.
3. To make the workpiece more easily and conveniently bent, a lever in the form of a larger diameter pipe or a strong rod can be placed on its opposite end.

Instead of a wooden template, metal hooks can be attached to the plywood along the corresponding bend line. Such a pipe bender will be good because hooks can be rearranged, thereby adjusting the bending radius of the workpiece.

In order to be able to bend a thick-walled product using such simple tools, it is recommended to use hand winch.

How to make a pipe bender with a pressure roller?

The tool, made from wooden rollers, has the advantage that the pipes are not deformed when used.

The material for the base of such a pipe bender is selected depending on the expected loads. Therefore, to make it, thick plywood or a sheet of metal is taken.

The holder for the pressure and central roller (template) can be made from a U-shaped metal blank. It should rotate freely around the central roller attached to the base. To holder the lever is attached in the form of a long handle, and on the base - emphasis.

For small workpieces, you can make a pressure pipe bender with your own hands for two different bending radii. For this the template needs to be made with rounded corners, each of which must have its own radius. The handle of such a tool should have two holes with which it can be removed and installed in another place.

Hydraulic machine for bending profile pipes

Making such a pipe bender with your own hands is a rather labor-intensive process. It consists of a hydraulic cylinder, pipe stops, a discharge device and strips.

In order to make a hydraulic machine you will need:

• hydraulic jack for approximately 5 tons;
• metal plates;
• channel;
• 2-3 videos;
• shoe.

First of all, you should make a structure from a channel, which should be equipped with rollers and a shoe. After this, the frame of the machine is made from a similar material.

The last platform of the machine will need to be reinforced with metal plates. After this, a jack is installed on this shelf. The structure is secured with bolts and a handle is attached to it.

Rollers made for a hydraulic pipe bender are installed at equal heights in a rectangular channel and secured with bolts. Below you will need to install a shoe. The location of these elements determines the required bend radius of the pipe.

The hydraulic driven machine is ready. More detailed instructions for making it yourself can be seen in the video.

Bending technology:

1. The pipe is inserted into the shoe and secured on both sides.
2. Next, the jack is used, the handle of which must be slowly rotated.
3. The force created by the hydraulic drive will be transmitted to the roller and the product will begin to bend at a given angle.

The operation of the machine can be stopped at any time. And to pull out the pipe, it will be enough to turn the handle in the opposite direction a couple of turns.

You can bend profile pipes at home using a variety of hand-made structures. Both home craftsmen and professional engineers are increasingly improving homemade pipe benders, drawings of which can be found on the Internet.

It is necessary to pay attention to the mechanisms discussed in this article. To make a pipe bender for profile pipe do it yourself - explore detailed instructions, video, photo, drawings. Using these materials, it is not difficult to implement the corresponding project.

Do-it-yourself pipe bender for a profile pipe: basic data

Before you study working documentation and algorithms installation operations, the intended purpose of the product must be precisely determined. A pipe bender for a profile pipe with your own hands must be designed for certain forces, workpiece sizes, and materials. It is easier to establish meaningful criteria after familiarizing yourself with the parameters of devices tested in practice.

What are these devices for?

To create the necessary force, a lever mechanism is installed here. A metal pin is used to fix the free section of the pipe. It is installed in suitable grooves of the “comb” before performing work operations.

Using this factory sample as an example, it is easier to study the design features:

• Handle (1) regulates the automatic stroke of the piston in the opposite direction. This solution reduces the burden on the user.
• Installed inside the case hydraulic system. When the handle is moved up and down, a force of up to 150 kN is transmitted to the working piston (8). This is quite enough for quickly bending workpieces made of durable metals.
• Support rollers (3, 4) are installed in the required frame holes open type(5, 9). They do not damage the surface, but provide reliable fixation.
• This removable segment (6) is designed to be bent at an angle of 90°. But with the appropriate configuration, it can be installed on similar product different form.
• The robust housing (10) is mounted on three supports (7). Rubber pads prevent movement during work operations.
• In addition to cleaning from dirt, you should occasionally check the condition of the oil filter (11). No other regulatory procedures are needed.

In this technique, a workpiece of the desired shape is used. The pipe is pressed against it using a rotating roller and lever.

Important! Before bending a workpiece using a certain radius, you should study specialized reference books. They provide data on permissible deformations of pipes made of different materials, with different wall thicknesses. If these instructions are violated, visible or hidden defects will form in the finished products.

Relatively small mechanical loads on working tools are created by levers and manual force. To work with durable metals The equipment is equipped with hydraulics.

Making a pipe bender with your own hands for a profile pipe: drawings and other preparatory operations

A simple device for bending aluminum and plastic blanks is shown in this figure.

To make such a structure you need a strong one. After marking, a round profile is cut out of it. The remainder is used for making support element. The created parts are rigidly attached to the supporting surface. To ensure the strength of the connections, in addition to screws, clamps are used. Next, the pipe is bent by hand until the desired shape is formed.

Before creating this simple pipe bender for a profile pipe with your own hands, it is recommended to make a basic drawing with dimensions. A template from thick paper, cardboard on which the markings will be applied. It is clear that to produce more complex structures it is necessary to prepare complete design documentation.

It is not necessary to strictly adhere to engineering standards in order to make a pipe bender for a profile pipe with your own hands; a schematic image is quite enough. You just need to indicate all the dimensions, decide on the materials, technological process And components. The project will help solve several practical problems:

• During the preparation process, it will become clear whether it is necessary to use other special equipment.
• Full list necessary components details will be needed for targeted visits to certain stores.
• We must not forget that the machine must be protected from adverse external influences using wood impregnation.
• Some parts will be too difficult to make yourself. Appropriate orders should be placed in specialized workshops.

Important! When bending strong metal pipes it takes a lot of effort. In order not to take unnecessary risks, you can use drawings of a proven design, or copies of an industrial design.

Making a manual homemade pipe bender for a profile pipe with your own hands: video and detailed instructions

Here we talk about how to quickly create a pipe bender with your own hands for a profile pipe (video).

The master used available materials, a channel, and part of the drive from an old bicycle. But he had to create the connections himself to ensure the integrity of the heavy structure.

To find out how to make a pipe bender for a profile pipe with your own hands, the drawings and videos are supplemented with descriptions of work operations. Below are the algorithms for several assembly technologies.

Rolling pipe bender

Drawing	Actions
	To create a high-quality one, you can use this drawing as a sample. Here the workpiece is placed between three rollers. The extreme ones (2) – perform supporting functions. To install them at different distances (to obtain the required bending angles), grooves are made in the support strips (1). The necessary pressure is created using a screw mechanism (6, 7). The force is transmitted through the central roller (4), which is rotated by the handle (5).
	Holes in lower parts created according to these dimensions. A channel with a wall thickness of 4 mm was selected for the workpiece.
	The upper part is created with cutouts. They must be made level so as not to interfere with the movement of the support screws.
	The thread is cut in accordance with this pattern.
	For the handle, you can choose a finished product, or use these sizes.
	Once assembled, you will get such a cute and functional product. There are no welded joints. But the components are difficult to make on your own without professional skills and specialized machines.

Hydraulic pipe bender

The screw mechanism performs its functions too slowly.

This design uses a standard jack. It is fixed rigidly to a bar, which is suspended on two springs. This solution simplifies manipulations with a heavy jack when installing workpieces and clamping segments.

The pipe rests on two round pins. They can be rearranged into other holes to create products with the desired radius of curvature. Parts of a durable steel frame (4-5 mm) are bolted and welded joints. The design turned out to be collapsible. If necessary, it is not difficult to dismantle it. The jack can be used for other operations.

Holes are created at the base of the frame. Through them the machine can be firmly attached to wooden floor nails, screws. This gives additional stability stationary structure. Its metal parts are degreased, coated and painted. Besides the good appearance provided good protection from destructive processes.

For your information! While creating homemade pipe bender for a round pipe, rollers, stencils and segments with a different shape of contact surfaces are used. The technologies used are the same as for bending profile products. The above drawings with appropriate modifications will be useful.

In construction there is often a need to bend metal strips or pipes. If it is not possible to visit workshops that specialize in this issue, making a pipe bender for a profile pipe with your own hands. Having a similar tool at hand, it is easy to make trellises, arches for climbing plants and grapes. It will also help in the manufacture of gazebos, canopies, extensions or greenhouses, fences and even metal frames for furniture.

What does a pipe bender look like?

Pipe bender is special device, which helps to smoothly deform pipes made of steel, aluminum, copper, polyvinyl chloride and other materials. The bend is made from 0 to 180˚ if the diameter ranges from 5 to 1220 mm.

The pipe bender forms the product without damage or kinks.

Based on the installation method, a distinction is made between stationary and portable devices.

By type of drive - manual, electric and hydraulic.

Pipe bender for working with pipes and metal strips

Reliable lever or screw device

The device consists of three shafts. There are two support rollers in a static position on the frame. They are rotated by a handle mounted on the neck of one of them. The material feed rollers come in uniform motion thanks to the connecting chain.

A pressure roller is installed in the guides. The screw raises the guides and lowers them in a vertical rigid frame. As you can see, the diagram of a pipe bender for a profile pipe with your own hands is simple.

The first stage in the manufacture of such a device is the formation of the frame. To do this you need to take the corners. You will also need a double-row chain and sprockets. To make a handle that rotates the shafts, a calibrated rod and wrench. For further use, a cut is put on the handle. This is done to prevent the appearance of calluses on the hands.

The shafts will have to be ordered from a turner. To prevent the material from sliding to the side along the pipe bender, a special groove is made in the device according to the size of the profile (+ 2 mm). The journals are forced out on the shafts to accommodate the working bearing and sprockets. In addition, keyways for fastening will also be required. The size of the groove on the gear determines its width. The depth will be equal to half the height of the key used on the car for the same sprockets.

Rollers between which the pipe passes

To prevent the screw of the device from being worn out during operation, a copper or cast iron plate is fixed to it.

For high-quality bending, the pipe is placed on the feed rollers and carefully pressed. After this, the starting point of the radius is determined. It coincides with the center of the roll located on top. The handle is rotated in the required direction, while moving the pipe using feed rollers. At each pass, stops are made during which the screw is turned and the radius is checked.

When we do profile pipe bender pipes with our own hands, we carry out modernization. In order not to rotate the heavy handle, it is enough to make a drive.

Some profile benders use adjustable rollers to bend pipes.

Instead of a handle, a pulley is installed. For good rotation, it is better to use a V-belt drive. If there are overloads in the network, it will not break, but will simply stall.

The electric motor can be taken from the old one washing machine or from the pump.

By making 5-6 shaped cuts in the feed rollers, repeating the cross-section configuration, you can achieve the versatility of the device. This tool will bend not only profile pipes of various sections, but also water pipes and metal strips. The technology for making a pipe bender for a profile pipe with your own hands is similar to one standard size, only the drawings of the feed roller barrel differ.

Lever pipe bender diagram

We make one-time pipe benders

If there is no need for permanent job device, it can be simplified. From boards that are larger than the profile, we make a bending template. The finished configuration is fixed on the shield. Initially, a clamp is nailed to hold the object, then strips are attached in several places (they protrude beyond the edge of the shield and limit the rotation of the profile).

After installation, the end is inserted between the clamp and the template and gradually pressed against the surface. A rod lever can help with this.

It turns out to be an excellent pipe bender for a profile pipe with your own hands, the dimensions of which can be any.

Diagram of a pipe bender you can make yourself

For this, a hardwood is selected. Oak or regular pear will do. Formation wooden elements performed on home machine: mounted on the rotating part wooden block, and a wood cutter gives it required form. It is important to use the lever carefully. We perform rotating movements smoothly, without jerking.

Pipes small size plastic and soft, therefore wooden structure bends up to ten profiles.

If there is no chain, we help move objects between the rollers ourselves. They need to be pushed by hand along the axis. Press with the end wide board, which has pre-rounded corners.

When making a pipe bender for a profile pipe with your own hands, it is important to understand main principle his works. It consists in the fact that the device deforms parts using three points, which are located at a distance of 200-300 mm from each other. During movement, they limit the rotation of the object. Thanks to this, the profile will retain its cross-section, and the surface will remain smooth and undamaged.

Bending a pipe using a wooden template

Two pipe design

For such a tool you will need two pieces of steel. Their diameter should not go beyond 70-150 mm. The sections are concreted in vertical position. This could be a hole in the ground or a container that is no longer in active use. You can take a tall bucket, basin or plastic barrel. The main thing is that the distance between the tubes is 40-50 cm.

If it is not possible to concrete the pipes, they are welded welding machine to a reinforced base. As you can see, a manual pipe bender for a profile pipe, made by yourself, is a simple design.

The workflow itself is also simple. The bending pipe is inserted at one end into the gap between the previously installed steel sections. After this, it bends at the desired angle. This method Suitable for 40mm diameter.

To bend a pipe that is too short, fittings are inserted into it and then the work process is continued.

Pipe bender with chain and sprockets

Heated pipe bender

Thanks to this method, the bend is smooth.

The essence of the process is that selected, sifted quartz sand. It does not stick to the walls, but when hot it acts on them. The pipe is closed on both sides with wooden plugs.

It should be taken into account that during the heating process gases and vapors accumulate in a closed space. To ensure they come out unhindered, small holes are made at the end.

The bending area is marked with chalk. To deform the pipe by 90°, a section equal to six diameters is heated (respectively, 45° is three diameters, 60° is four).

After heating, the pipe is carefully inserted into a self-made profile pipe bender and bent according to the template. Drawings of such a device can be found for free.

You should not stop in front of difficulties; the problem can be solved if you approach it creatively. Of course, it is better to contact experienced craftsmen, but when there is no time to wait for workers to arrive or not additional funds To pay for their labor, you can bend the parts yourself.

Video instructions for making a pipe bender

A real owner always has plenty various instruments, which he uses for his house and plot. And he, of course, will be able to make a pipe bender for a profile pipe with his own hands according to the dimensions and drawings that we will provide below. Such designs may be different, and we will not be able to cover them all, but the material provided will be enough for you.

Homemade pipe bender

Buy in a store or make it yourself

Profile pipe bender "Hercules"

The one you can buy in the store may have different type drive and different principle actions, but this is not always good. Firstly, to work on it you need some experience, and secondly, such devices have high cost. For these reasons, making a homemade pipe bender from scrap materials is not only profitable, but also practical, since when assembling the tool you will know the slightest nuances of its operation.

Why do you need a pipe bender?

Main elements of the machine

Today, profile pipes of different cross sections are the most popular metal products. They are used to make frames and lathing, fences and railings, with their help they expand balconies and even build various architectural structures in the form of extensions or separate rooms. But sharp turns are not always used in construction - sometimes a smooth transition is also needed, and in these cases it is impossible to do without a pipe bender. As a rule, such a machine allows you to bend a profile to an angle of 180⁰, that is, the device allows you to make a circle.

Main design elements

Principle of operation

To manufacture a particular machine design, you should look through several diagrams to determine the set of parts. The fact is that, if necessary, all the components of the units can be purchased for money, but you can also use the materials that you have on your farm and not pay anything for it. In most cases, home craftsmen opt for frontal structures, and for this you must have:

• three metal rollers (rollers);
• drive chain;
• axes of rotation;
• drive mechanism;
• metal profiles (channels) for the frame.

Sometimes, in the absence of metal rollers, they are replaced with wooden or polyurethane ones, but... Such a rolling mechanism will not withstand long-term load, that is, the machine will serve its purpose, but not for long. Is there any point in wasting your labor for short-term benefit if, with some effort or even paying a certain amount, you can find steel rollers?

Scheme simple pipe bender with dimensions in mm

As you understand, the process of profile deformation occurs using rolling, that is, the pipe is rolled over rollers (rollers), which eliminates breaking and cracking. To roll (bend) a profile, it is inserted into the rolling line (between the rollers) and pressed from above with a screw device or a jack to the desired bending radius. Then, when the feed handle is rotated, the pipe moves and the bend runs along its entire length. It turns out that this is a manual drive, which is driven by muscular force, but at home such a mechanism is very convenient.

The profile is pressed using a jack

To assemble the simple pipe bender in question with your own hands, you will need:

• jack (preferably rack and pinion type);
• metal profiles with a shelf for horizontal and vertical frames;
• springs made of alloy steel (they are distinguished by high strength);
• three steel shafts with bearings;
• drive chain (can be from a bicycle or moped);
• gears (driver and driven);
• Thick reinforcement for axles and drive handle.

Video: pipe bending process

As you can see, it is easier to make a profile bending machine yourself using the existing drawings, and photo and video materials only help with this. The profile bender shown in the picture is driven by a handle that rotates the shaft with the drive gear. Using a chain, rotation is transmitted to the shaft with the driven gear, and the third shaft presses the profile from above to the required bending angle. Everything is very simple.

Mechanism manufacturing process

Bending device drawings

If you are interested in how to make a profile bender, then you will have to perform a number of actions that will ensure this reliability of the mechanism, and this is:

• production of a powerful frame assembled using welding and bolt ties;
• according to the terms of the drawing (technical specifications), make and install rotation axes for the rollers. There are three of them - two rolling and one clamping;
• To rotate the rolling rollers, you need to provide a chain transmission, that is, weld (evenly) the drive and driven gears;
• Weld a handle for rotation onto the drive gear.

Manufacturing nuances

Ready pipe bender

If you have everything in stock necessary details, then it is not difficult to make a mechanism for bending the profile. First of all, you need to take into account that all rollers must rotate on bearings - the accuracy of rotation will ensure correct rolling, without failures or breaks. The drive and driven gears must be correctly centered - a deviation from the center by at least 0.5 mm will lead to incorrect deformation (the bend will be uneven).

The pressure shaft must also be centered - the accuracy of the bending angle depends on this. It is best when the dimensions of all three shafts are the same - the rental is the clearest. The rolling accuracy also depends on the rigidity of the clamp, so the shaft must be well fixed.

Hydraulic pipe bender

Hydraulic drive mechanism

To make a hydraulic one for a profile pipe with your own hands ready sizes and drawings, you will have to spend a lot more labor and resources. However, it can be done and we will now look at the procedure. For assembly you will need:

• hydraulic jack with a lifting capacity of 5 tons;
• shoe;
• three shafts;
• channel for frame;
• metal plates (thick).

Video: hydraulic driven mechanism

To correctly bend the profile, it is inserted into the shoe and both ends are secured. After this, the jack is activated - it presses on the pressure shaft and sets the desired bending angle. After rolling, the jack is loosened several turns and the pipe is removed from the device.

Drawing with dimensions in mm

The jack is attached to metal plate with help bolted connections. But in such a mechanism, the most important thing is the shafts, which must tightly grip the profile - the accuracy of bending depends on this. The shafts are fixed at the same height and gears are welded to them. The shoe is attached below the shafts, and the ratio of the shoe to the shafts determines the bending angle. Fixation occurs using bolts.

Bending Methods

Cold profile bending

If you have read all the descriptions, looked at the photos and videos, then the bending process itself is unlikely to confuse you. If you decide to make a hydraulic device, then you can bend pipes of any thickness on it - the most important thing is that the shafts (rollers) can withstand it. But I would like to mention one nuance - arching can be not only cold, but also hot. Heating usually occurs using gas welding, this is very convenient, especially since you can heat only part of the pipe, that is, the section that needs to be bent.

It can be said that cold method arching is the simplest and if you are working with thin-walled pipe, then there is no need to heat it at all. But there can also be problems here - this is the seam. Profiles are not always made with high quality and a bad seam simply comes apart when bent. This can be avoided by heating, but not always. A low-quality pipe will remain that way and no amount of heating will help. However, if you use a profile for the frame, then a small crack along the seam will not become critical.

Note. Be that as it may, hot bending is still the highest quality. Hot metal it turns out to be most clearly curved, without any interruptions.

Pipe bender with components

For a profile pipe, it is not at all necessary to acquire any special qualifications - ordinary care and a few recommendations from specialists are enough. IN hand-held devices the system consists of a drive and driven gear welded onto shafts and a clamp (a jack can be used instead of a shaft). Sometimes the profile may slip off rolling mill and in such situations, hooks are used for fixation. For the most precise bending, the shafts must be movable.

Note. To maintain the bend radius, it is best to make a cardboard or wooden template. Even if you use a simple hand pipe bender, a template will always ensure accuracy.

Conclusion

You have read an article with drawings, photos and videos about how to make profile bending with your own hands. As you can see, this is not very difficult, but you need to collect all the parts first so that the work does not stop because of the little things.

Making a pipe bender for a profile pipe with your own hands is not very difficult; for this you need to stock up on drawings, a small amount of metal and patience.

There are many various types pipe benders, in this article we will look at an example of creating a rolling profile bender.

Classmates

Application of pipe bender

A profile bender will allow you to easily make a beautiful shady canopy for the yard or for a car

With the help of such a device it is easy to create metal structures of various shapes.

Smooth, rounded lines look more attractive on a variety of products than sharp ones.

Tables with metal legs fancy shapes, park benches and much more are made using this tool.

DIY profile pipe bender

There are pipe benders different types and have Various types mechanism. We will look at a rolling pipe bender with three rollers and a manual drive.

“Rolled” means that the workpiece that is to be bent is not fixed in the mechanism, but changes its diameter by rolling along its entire plane. This approach makes it possible to obtain workpieces of practically unlimited length and a very large radius.

In order to obtain a small but even bend along the entire length of the workpiece, you need a rolling pipe bender.

The pipe bender drive can be mechanical (manual) or machine (hydraulic or electric). To reduce the cost and simplicity of the design, it is better to use a manual drive; this will allow more precise control of the process of creating a workpiece on initial stages and adjust your actions as you work.

Note: manual drive will not require any special physical skills from you.

The design of the pipe bender under consideration involves the use of three rollers, two of them are the main ones, they support the workpiece and are fixed depending on the required radius, at an equal distance from the central (pressure) roller. The pressure roller is located in the center and is designed to apply a certain pressure to the workpiece to bend the product.

Drawing of a rolling pipe bender

The figure shows an approximate layout of the pressure (3) and main (1,2) rollers. This scheme is quite functional, but the lower location of the pressure roller imposes restrictions: thus, the bending angle will be directed downward, and therefore the long workpiece will rest against the base of the entire structure or the floor.

You can avoid this by installing the profile bender on a special frame; this will make it possible to make large angles, but still a very long pipe can rest against the floor, and it is impossible to endlessly lift the entire structure up.

There are no disadvantages in the design of a homemade pipe bender with an upper pressure roller previous version: the pressure roller “3” presses the workpiece, which is located on the rollers “1” and “2” from top to bottom.

As a result, the pipe bends in such a way that the edges point upward. If you use a pipe bender outdoors, you can bend a pipe of almost infinite length.

As for the “4” clamping mechanism, it is often made using a screw axle from an old vice or another strong screw. You can also use various jacks. If you took a manual jack, then the entire structure is above work area will be occupied by a large “superstructure” for installing the jack; in this case, it is easier to remove the mechanism from it and install it vertically on the product.

It makes sense to use a hydraulic jack if the profile pipe intended for bending has a very thick wall. In this case, manual effort may not be enough and you will need hydraulic assistance.

Note: The power of the hydraulic jack must be at least 5 tons, otherwise difficulties may arise.

The rolling mechanism “5” must provide movement to the pipe for smooth bending in the entire plane. In the drawing, the handle of the mechanism is firmly fixed to the pressure roller, and when rotated, it rotates the roller itself, which in turn moves the pipe. This approach has a right to exist, but it also has disadvantages.

When you need to bend a pipe with a thick wall, the force applied to the pressure roller can be so strong that it will be problematic to turn the workpiece or the roller may simply slip.

In this case, the mechanism is transferred to support rollers “1-2”, bicycle sprockets are installed on the rollers and connected with a chain, and the handle is installed either on one of the rollers or on an additional third roller, which can act as a “tensioner” for the connecting chain (as shown in the picture).

Take note: choose the size of the product based on your personal needs, but remember the safety margin.

Tools and materials

In order to make a pipe bender yourself, you will need some basic set of tools, such as:

1. Welding.
2. Bulgarian.

In addition to tools, you will also need a certain set of materials:

• sheet metal (minimum 4 millimeters) or square pipe with a wall of 3 millimeters or more;
• rolling rollers;
• bearings 6 pcs. (along the diameter of the roller axis);
• bolts 8 pieces;
• chain;
• clamping mechanism (strong screw or jack).

Take note: if you order rollers from a turner, spare no expense and turn several sets with an internal groove, under different widths profile. Such a limiter will not allow your workpiece to move in the plane and guarantees you an even pipe at the exit. It is better to buy bearings that have their own housing.

Build process

1. The first step is to create the frame of the future product; you should not skimp on metal. If you use metal that is too thin, your pipe bender itself may bend, and then the pipe will turn out uneven, or the pipe bender will stop working properly altogether.
2. We prepare the frame for installing rollers and mechanisms on it: we drill slots and holes for installing parts, and weld the necessary fasteners.
3. We install rollers and a clamping mechanism.
4. The last stage is to install a chain drive on our mechanism.

That's all, a pipe bender for a profile pipe with your own hands is ready for use. You can take the first pipe and test the effectiveness of the device by bending it. If everything is in order and no shortcomings have been identified, then paint your new profile bender to protect it from corrosion and it will serve you well long years. So, at home, you can make a tool with your own hands that will make your work easier.
