Description

A stamping die with an easily replaceable stamping head

Technical field

The utility model relates to the technical field of stamping molds, specifically a stamping mold with an easily replaceable stamping head.

Background technique

Stamping die is a special process equipment for processing materials into parts in cold stamping processing. It is called cold stamping die. Stamping uses a die installed on a press to exert pressure on the material at room temperature to cause it to separate or Plastic deformation is a pressure processing method to obtain the required parts. There are many forms of stamping dies, and the stamping dies also depend on the nature of the work and the mold structure. Stamping dies are generally equipped with a stamping head, and the stamping head is generally fixedly installed on the upper mold base. , but the stamping head is prone to damage after working for a period of time, which requires replacement. Therefore, the upper die base and stamping head are generally designed to be detachable and replaceable.
