Sale of metal band sawing machines. Band sawing machines for metal. Classification of band saws according to the degree of equipment automation

A band saw machine, which belongs to the category of high-power equipment, can be used not only for cutting metal workpieces, but also for sawing polymers, wood and other similar materials. It is noteworthy that a metal band saw can make not only straight, but also shaped cuts. Yet the main element of the machine is the band saw. This cutting element is presented in the form of a closed metal strip on which sharply sharpened teeth are located.

A metal band saw is equipped with several pulleys (usually two or three) that form a closed loop. A metal belt with teeth moves along this contour, performing the cut. A serious advantage of such saws is the long working life of the cutting metal blade and, accordingly, the absence of the need for frequent replacement.

Advantages of band saws

Buying a metal band saw is quite simple; this type of machine is presented in a wide range on the equipment market. However, you should not purchase the first machine you like; before purchasing, you should pay attention to its main characteristics - efficiency and productivity. These parameters directly depend on the installed electric motor that drives the pulleys.
Despite the fact that such equipment is highly powerful, these machines are very compact and can be easily used in private workshops. To install the band saw, no lifting equipment is required; the installation operation can be done by one person.
Another important advantage of band saws is considered to be high safety for the operators who work on them. The thing is that the movement of the cutting saw occurs towards the work table and the material being processed, due to which a possible “ejection” of the workpiece can only occur in the direction opposite to the operator.
Regardless of the modification, almost all band saw machines consist of the following components:

• ✓ drive mechanism;
• ✓ body;
• ✓ mechanism for loading and feeding the workpiece;
• ✓ unit responsible for the cutting process;
• ✓ control system, which includes hydraulic and electromechanical components.

Design “variations” of machines

Types of band saw machines can also be divided into groups according to design features.

• ✓ Cantilever band saws (sometimes also called rotary) - are a frame with a saw attached to it (console), which, in turn, is lowered or raised thanks to a hinge mechanism. This method of securing the cutting unit is very convenient when cutting rolled products, profiles or pipes is required. These types of machines are either fixed (they can only cut at an angle of 90 degrees) or rotary (they can cut at almost any angle).
• ✓ Single-column band saws are equipment in which the saw frame is located horizontally and moves along a vertical column. The workpiece is mounted on a stationary working surface, and during the cutting process, at the required angle, the frame is rotated relative to the axis of rotation - the stand.
• ✓ Double-post band saw machines are equipped with a cutting unit that moves along two vertical posts at once, which, in turn, allows you to create more pressure on the material being cut without compromising the accuracy of the cut. If the workpiece needs to be cut at an angle, then in this case the work table itself rotates, on which the part is clamped in a vice. Due to the increased rigidity and stability of the design of such machines, they are often purchased for the purpose of cutting metal.
• ✓ Portal band saw machines are equipped with a fixed functional surface with guides along which the portal with the saw frame moves. Such equipment has significant dimensions, as it is designed to work with large-sized workpieces.
• ✓ Vertical band saws have a tilting and movable frame with a saw. In the first version, the frame runs across the working surface, while cutting is carried out at an angle to it - such machines are used for cutting pipes and angles, as well as when cutting solid workpieces. In the second case, the cutting element moves along guides both along and across the desktop.
• ✓ The frame in angular horizontal machines can be rotated relative to its vertical axis - this makes it possible to quickly reconfigure the cutting angle of workpieces

For most models of band saw machines, the main element is a belt that is tensioned between two (three) pulleys. After turning on the machine, the belt immediately starts moving, which allows you to cut workpieces without delay.
A design feature of the band saw machine is the uniform distribution of the resulting pressure on the workpiece, thanks to which the operator can make precise cuts. It is also very convenient that the cut can be made not only perpendicular to the axis of the equipment itself, but also at an angle of up to 60 degrees. Changing the cutting angle is achieved by changing the position of the cutting blade or rotating the work table.
When performing its direct functions, the cutting blade becomes very hot, which can ultimately lead to failure of the entire device. In order to protect the machine from overheating, coolant (cutting fluid) is supplied to the cutting site, which not only protects the blade from high temperatures and rapid wear, but also prevents chips and metal dust from entering the environment.

Coolant supply to the cutting zone

Metal processing can be carried out at a right angle or a given angle not exceeding 60º. Changing the cutting angle is done by changing the position of the cutting saw when turning the frame. The cutting process is controlled by sensors, and the working contact area between the metal being processed and the saw is cooled using the supplied coolant. Water or a special emulsion can be used as a coolant, which also washes away chips and metal dust. Some models of machines are equipped with cleaning brushes that remove metal shavings, thereby facilitating better sawing of metal and increasing the service life of the blade.

Benefits of use

Over time, the technical sphere does not stand still; on the contrary, it is constantly developing and providing its innovative developments in various fields and branches of science. Therefore, enterprises try to use the most highly productive, efficient and innovative inventions in production. A metal belt machine is one of these.

Multifunctional inventions include such a useful thing as a metal cutting machine. It is also called a mechanical saw. Many industrial organizations that work or are closely associated with metal, its processing and cutting are trying to acquire this device.

What is the machine for?

Before purchasing a metal strip cutting unit, you need to learn more about it: characteristics, purpose and types.

This device has very high power. Cuts metal, wood products, plastics. Works in both straight and figured cutting modes. Works with various sections and sizes of objects requiring detailed processing of each side.

An additional powerful unit processes objects made from the following alloys:

• steel and its alloys;
• non-ferrous metals and materials of increased hardness;
• titanium.

The main function of the band device lies on the saw, it looks like a strip made of steel with teeth.

The functional teeth are made of high-speed steel material. The movement proceeds without interruption in a given direction. Sawing is possible with the help of several supporting clamps, gradually building up pressure.

Due to the fact that the equipment is high-tech, the work is performed efficiently and quickly. The tape blade lasts for quite a long time, until the tool stops sawing due to dullness of the teeth.

And you definitely won’t have to replace the tool after a few months.

Features of the Band Cutting Machine

Due to its characteristics and efficiency, a metal cutting belt cutting machine is simply necessary for enterprises specializing in the metalworking of large parts and shaped products.

The device has wheels surrounded by a rim. They allow other elements of the machine to move. Wheels are one of the main transmission elements; they are called pulleys.

The circular motion of the pulley occurs due to the operation of an electric motor. It is additionally responsible for the efficiency and accuracy of the metal band saw.

When choosing and purchasing a tool, you need to look at the characteristics and parameters of the electric motor, its power and the country that produces its parts.

The main advantages of a metal cutting machine should be highlighted:

• durability;
• made from high-quality and durable materials;
• simple and safe use;
• refers to high-tech equipment.

When the saw moves, there is a strong pressure from it on the object. It goes towards the workpiece being processed, with which contact occurs. This device has a lot of advantages.

Among all the equipment, even the small and therefore convenient size wins. Therefore, if necessary, it is easy to work in a narrow space without problems. If you plan to use the tool in everyday life, you should safely take models made for workshops. They look smaller than regular saws, but their mass is small.

This is quite convenient, since it does not require the use of special equipment for transportation and subsequent installation of such a machine. When the belt with the canvas moves, the work occurs quietly, these elements are built in taking into account the current vibrations. This factor is the main advantage of the equipment.

Unit operation

A metal band cutting machine has its own operating principles and individual structure.

Despite the fact that there are many species, they all have common features. The characteristics are indicated in the technical documentation of the unit and are subject to careful study before purchase.

The machine consists of the following structures:

• main body;
• saw unit;
• electromechanical and hydraulic equipment;
• block for supplying objects;
• drive mechanisms.

The capabilities of the machine are great, because the belt is tensioned on the flywheels, the design smooths out all the sharp corners. The unit operates in the drive mechanism, and the activity is performed as follows:

• first the machine must be turned on;
• the belt automatically starts moving;
• The object is being prepared and the cutting process is taking place.

The cuts are accurate, this happens with the help of uniform pressure during operation.

Specialists can also operate the device at an angle. In such a position, a metal cutting belt cutting machine will make processing easier. To prevent overheating, you need to use a liquid that will perform two functions at once: lubrication and cooling.

To perform this procedure, you must use ordinary water or a special liquid. It must be applied to the blade for washing to occur. This not only cleans the device, but also helps protect against failure or breakdown.

The equipment is cleaned with brushes provided by the manufacturer. They eliminate small particles, dust, debris, wood or small metal shavings. Thanks to this, the work is carried out smoothly.

Varieties

Band cutting machines for metal come in different models and types, as well as the purpose of the unit in the production process.

A popular type of equipment for this type of equipment is the carbon band saw. This device is designed to work with unalloyed steel.

Another type is bimetallic, its purpose is to cut heavy and hard objects.

The carbide saw is designed for difficult-to-cut metals. These can be cast iron and titanium products. Diamond saws are used for abrasive materials.

Saws are also classified into groups. Pendulum or cantilever can move up and in the opposite direction, as well as make circular movements. Such devices are indispensable for all kinds of pipes. They also differ in the control system.

A column or single-post saw has a horizontal position and moves along a vertical post. Two-post or two-column units move along two vertical posts, they are located on the sides.

If you need to work at an angle, use a rotating table. There may be a stationary table, but the saw itself is in constant motion. These machines can have a permanent or maneuverable mode, auto or semi-automatic mode, depending on the functions they perform.

In some industries, specialized machines are found: with vertical manual stands, with a tilting frame, with a movable frame, with movement along and across the table, with a variable tilt.

Saws are divided into types and automation

Metal cutting machines are divided into certain automation classes.

they are:

• gravity or manual;
• automatic and semi-automatic.

In manual cantilever units, the frame is lowered due to human work, and in gravity units, due to the mass of the frame. With this operating mechanism, the feed speed is regulated by a special cylinder with a valve. This type of work is called hydraulic loading; it is used when you need to fix the frame at one point.

When working, the master independently installs and secures the object in a vice for cutting. The speed can be set manually or from the remote control.

But manual frames have a number of advantages over other types:

• bevel cutting;
• cheap repairs;
• loyal price.

The hand saw also has disadvantages:

• Vibration during cutting, which reduces the life of the device.
• It is difficult to control tension and clean, so the pulleys need to be adjusted periodically.
• It is difficult to control the pressure on the object.

A hand-held metal band saw is used in small companies for tools and stainless steel, as well as for profiles. In semi-automatic frames it moves up and down, the vice is clamped and unclenched mechanically through a drive, the object is installed manually.

Features of units on the market

Popular models are semi-automatic, they are suitable for small organizations. They can be used to work from different angles. This manipulation simplifies working with shaped parts.

As soon as the machine is turned on, the object is clamped and cutting occurs. Pressure occurs using a frame and a hydraulic cylinder. Therefore, even stainless steel materials are sawn.

But at large enterprises and in industry, automatic belt machines are often used.

They are indispensable if you need to cut a whole series of different workpieces. Manipulation saves both the time and effort of the craftsmen. Because a person is only required to configure certain parameters and set the workpiece for cutting. After this, the entire process proceeds automatically, the force at each stage is set individually.

To avoid unforeseen situations related to the saw, the technician needs to slow down or stop feeding the frame while the pressure is increasing.

Automatic devices are better than their mechanical predecessors and are more efficient in operation. They cope with any task and can make any corner cuts, work in three modes, and cut long parts without a master.

Machine in operation - advantages of processing

A metal cutting machine is used to produce parts for transport and mechanics. It is used for processing elements in the manufacture of vehicles and machines. But even with all its simplicity, the unit has its own nuances - large allowances. All this is due to the low accuracy of preparation.

There are several cutting methods:

• using circular saws;
• using incisors;
• hacksaw blades;
• diamond wheels;
• band saws.

It is easier to work on a band saw, since the master is able to complete the cutting faster and with greater accuracy, and the cut is smooth. Material is saved, specialists can work at an angle, and also cut various difficult-to-cut objects.

Technical progress does not stand still, forcing manufacturers of metalworking equipment to implement the latest achievements of science and technology into modern high-tech equipment. Band sawing machines for metal were no exception and fully comply with the requirements of the time.

PJSC Kuvandyk Plant KPO Dolina is one of the few domestic manufacturers of band sawing machines that has mastered and offers customers a full range of additional capabilities for the entire line of manufactured machines.

Our factory produces band sawswith varying degrees of automation, allowing cutting of almost any rolled product. The entire line of machines is designed in such a way as to ensure the most uniform distribution of pressure on the workpiece during the cutting process, which allows for very accurate cuts. Depending on the selected configuration, metal cutting can be performed either perpendicular to the axis of the equipment or at an angle not exceeding 60 degrees. What is unusual is that miter cutting is achieved either by rotating the moving part of the vice or by rotating the work table.

To equip serial production, where there is a need to cut a large number of similar workpieces, we use automatic metal band saws. If it is necessary to make several single cuts, such band saws are switched to manual control mode.

Automatic machines can operate according to a given program without the presence of an operator, performing the same type of operations (cutting long workpieces into parts of a given length) a specified number of times, which allows one operator to service several machines at once.

It is also important to use in large quantities batch cutting of blanks from a profile with a small cross-sectional area. Our company offers consumers two options for solving this problem:

The first method is to use additional devices to obtain the so-called “hexagonal vice”. Hexagonal vices make it possible to most compactly place workpieces with a round or, for example, hexagonal cross-section into a bag, which is very difficult to do when using a conventional vice.

The second method involves the use of additional upper pressure. When using the top clamp, workpieces of almost any profile can be placed in a relatively compact package. When using a conventional vice, it is problematic to achieve reliable fixation of a package of workpieces with a small cross-section (for example, welding the ends of the workpieces or tying the package with wire is used).

High productivity of metal cutting (even when using such additional options as batch cutting) cannot be achieved without using automatic feeding of workpieces. Automatic feeding can be carried out in different ways: the use of feeding roller tables in conjunction with control electronics; embedding feed rollers into a vice or machine table; etc., but all these methods are not applicable when using batch cutting. When cutting metal with a package, this same “package” must be constantly clamped in a vice. The solution to this problem was the use of additional feed vices on our automatic bandsaw machines..

The use of this principle of automatic feeding when using batch cutting allows you to significantly increase the productivity of the equipment, and also significantly reduce the time spent by the operator.

It is important when using band saw machines ability to cut metal at different angles. Most manufacturers offer fixed cutting angles, such as 15, 30 or 45 degrees. On the machines of PJSC Kuvandyk plant KPO Dolina it is possible to cut metal l la at any angles in the range 0±45 or 0±60 degrees.

The engineers of our company managed to realize this opportunity by changing the principle of cutting at an angle. While most of the world's manufacturers use the principle of rotating the workpiece relative to the band saw, our designers have implemented the principle of rotating the machine relative to the axis of the workpiece.The profitability of this solution is fully visible when calculating the required area for equipment.

The use of all of the above functions when working on band saw machines produced by PJSC Kuvandyk Plant KPO Dolina provides undeniable advantages:


It should be remembered that no matter what degree of automation the machine has must be strictly observedmaintenance regulationsand monitor the accuracy of the resulting cut, for which you need:

• choose the right saw blades;
• choose the right coolant;
• monitor the tension of the canvas;
• lubricate and clean moving parts in a timely manner.
