Description

Technical Field

[0001] The utility model relates to the technical field of bending, and specifically relates to a bending mechanism for metal parts. Background Technique

[0002] Metal bending is a process in which a metal sheet undergoes elastic deformation under the pressure of the upper die or lower die of a bending machine and then enters plastic deformation. In the initial stage of plastic bending, the sheet is freely bent. As the upper die or lower die presses on the sheet, the sheet gradually presses against the inner surface of the V-shaped groove of the lower die. At the same time, the radius of curvature and the bending moment arm gradually become smaller. Continuing to apply pressure until the stroke ends, the upper and lower dies and the sheet are in full contact at three points, and at this time, a V-shaped bend is completed.

The setting of the template and the bending plate places the metal sheet on the template, aligns the bending position with the lower end of the bending plate, controls the power-on operation of the press through the button switch, the press drives the fixing plate and the bending plate to move downward, and bends the metal sheet through the cooperation of the bending plate and the bending groove.
