What should be paid attention to during bending of the machine tool sheet metal outer cover?

The outer cover of the machine tool is a protective cover for protecting the whole machine. The bending of the sheet metal part directly affects the later assembly. It is better to do it in the case of bending, and it is less troublesome and efficient when it is assembled later. Bending is a major part of the manufacture of machine tool sheet metal shields.

Machine tool sheet metal outer cover bending is important to pay attention to, then what should you pay attention to when bending? Let's talk about this issue below.

The bending of the sheet metal parts should consider the processing capability of the equipment as much as possible, which directly affects the appearance of the sheet metal parts and the appearance of the shape. The selection of the tonnage of the bending machine is calculated as:

P=650S2L/V

P----bending pressure (KN) in the formula;

S----board thickness (mm);

L----board width (m);

V----The size of the lower die opening.

Machine tool sheet metal outer cover sheet metal parts are generally divided into three types: one is free bending (also called hanging bending); the second is pressing bending (also called mold forming bending); three is three points Bending, which is characterized by three points of contact between the workpiece and the lower mold. When the upper mold presses the workpiece, the middle portion moves with the workpiece, and the position of the workpiece is fed back to the computer to ensure the accuracy of the bending.

The bending process of sheet metal parts is a bottleneck in the whole process of protective production outside the machine tool, and its processing speed is relatively slow, so choosing the correct bending equipment and bending method directly affects the overall production efficiency.
