Description

Stainless steel plate stamping deformation mechanism with limiting device

Technical Field

The invention relates to the technical field of stainless steel plate processing, in particular to a stainless steel plate stamping deformation mechanism with a limiting device.

Background

Stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece of a desired shape and size. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products.

The stamping process is a production technology for obtaining product parts with certain shape, size and performance by directly applying deformation force to a plate in a die by means of the power of conventional or special stamping equipment and deforming the plate.
