Common methods of sheet metal forming

- Sep 06, 2019-

1. Separation

It mainly includes cutting, blanking (blanking, punching), cutting and so on.

Its characteristic is that the stress exceeds the strength limit after the plate is subjected to external force, which makes the plate split and separate.

2. Deformation

It mainly includes bending (bending and rolling), drawing, torsion, forming (undulating, flanging) and so on. It is characterized by the stress exceeding the yield limit but lower than the strength limit after being subjected to external force and forming a certain shape after plastic deformation.
