Sheet metal bending is a metal processing technique that transforms a straight sheet metal part into an angled component in a manner that causes permanent deformation. The process can be divided into three categories: local bending, closed bending, and embossing bending.

Local bending: The method for right bending and obtuse angle bending is to select an upper mold with a width of 88 degrees or less and a lower mold with a width of V=12t (slot width V, material thickness T).

Closed bending: Select the method of bending at right angles and obtuse angles of 90 degrees. The near bending lower mold is selected with V=6~12t.

Bending: 90 degree upper die is selected for right angle bending. (Standard right angle bending). The bending lower mold is selected as V=5~6t.

In order to improve the bending speed during the bending process of sheet metal processing, the gear switch can be operated in a single or continuous state, but for safety reasons, it is usually only used in a single action. When bending long parts, the angle in the middle is usually large. We can adjust the CC axis to change the middle angle to achieve the same angle as the left and right sides. During bending, attention should also be paid to the principle of central bending, which is an important prerequisite for ensuring bending accuracy.
