metal bending

Metal bending is a technology that allows the production of blanks or finished parts by deformation of a metal sheet. When bending, the inner layer of the material is compressed and the outer layer is stretched under the influence of pressure on the metal, which gives the effect of deformation and the part is obtained in the desired shape. Bending of sheet metal is carried out on specialized equipment – sheet benders. According to the principle of operation, metal bending machines can be divided into several types:

1. Universal bending machines.

During the operation of these types of machines, the sheet is placed in a fixed matrix of the machine and with the help of a punch it is deformed, giving the desired shape. The punches have a specialized shape, dimensions, are set at a specialized angle, which makes it possible to bend completely different sheets. Universal sheet bending machines are easily reconfigured and are able to solve many technological problems associated with flexible metal.

2. Rotary bending machines.

These types of machines consist of a specialized traverse, which consists of a bending beam and a backgauge. The clamping beam is necessary for fixing the metal sheet to the frame, and the bending of the sheet is carried out using a bending beam, which is the main working element of this type of bending equipment.

3. Rotary bending machines.

These types of machines consist of specialized shafts that rotate around their own axis and can also move in a vertical plane. A sheet of metal is placed in the space between the shafts and moving them vertically, the future bending radius is adjusted, after the sheet passes between the rotating shafts, it is deformed and receives the required shape.

Manual sheet benders.
As a rule, these are small bending machines that have a number of features, in particular, they have limitations, namely: the depth of laying the workpiece, the maximum thickness and width of the metal being processed, the bending length. The thinner the metal, the longer the bend. Most often, they are used for bending thin sheet metal. As a rule, the thickness of the sheet that can be processed by such a machine should not exceed 2 mm. The main advantage of manual bending machines is their low weight and mass dimensions, which allows them to be used not only in the workshop, but also directly at the workplace, such as a construction site.

Electromechanical sheet benders.
The design of this equipment consists of a frame and a rotary beam for bending the sheet. In addition to the rotary beam, an additional beam assembled from profile elements is installed on the machine, which presses the sheet. For the safety of the operator, pedal control is implemented on machines of this type. Sheet benders of this type allow you to bend metal with a large length. They are used for processing various materials, including galvanization, cold-rolled steel with a thickness of 2.5 mm. Machines of this type are used in the production of ebbs, window sills, structures for ventilation systems.

Hydraulic sheet benders.
This type of machine tool is most often used in large metalworking factories. They use a liquid as an energy source, which, due to the pump built into the system, creates excess pressure, under the influence of which the plunger moves the movable cross beam. The bending of the part occurs due to the fact that the metal sheet is first pressed against the desktop, and due to the movement of the transverse beam, the sheet sheet is deformed. Hydraulic plate benders are characterized by positioning accuracy and high work efficiency. Hydraulically driven machines are used for the production of precision components, air ducts, roofing parts, and other products. Such machines will allow processing metals up to 30 mm thick. It is hydraulic sheet benders that KSL uses for bending metals, and the most technologically sophisticated press used by our company is called DENER SX1560, MVD A100/2600, AMADA APX 8025.
