AI Technical Summary

Technical Problem

During the production process of cold heading machine, the blast material enters the main mold cavity unstable, resulting in drop, skew and the risk of mold impact, affecting the production yield rate.

Method used

A stable new cold heading machine feeding device is designed, including a mold cavity, an upper punch rod, an lower punch rod, a main mold pad and a polyurethane spring. Through the friction between the punch rod and the polyurethane spring, the blast material is ensured to ensure the stability of the blast material when pushed into the next sequence mold cavity.

Benefits of technology

It effectively solves the problem of unstable blast material entering the main mold cavity, reduces the risks of dropping, skew and mold impact, and improves the yield rate of production.
