Technical Field

The utility model relates to the technical field of stamping dies, in particular to a stamping die for multi-station assembly type automobile parts.

Background Art

Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. It is widely used in mechanical processing, especially in the automotive processing industry. In the process of automobile production and processing, a large number of automotive parts are formed by stamping.
