Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1: the utility model provides a progressive die stripper mounting structure, refers to fig. 1, contains upper die base 100 and stripper 200, is provided with four guide pillars 110 that the array distributes on upper die base 100, and stripper 200 movable sleeve is established on guide pillars 110, utilizes the guide pillars 110 that the array distributes for stripper 200 is more stable when sliding along guide pillars 110.

Specifically, a plurality of supporting pieces 120 are symmetrically arranged on the upper die base 100, the supporting pieces 120 are detachably connected with the upper die base 100, and the supporting pieces 120 and the upper die base 100 are fixed through a fastening piece 150.
