Thread rolling plate

The change of the structure of the edge-cutting die can lead to the change of its stress condition.Reasonable edge-cutting die structure can improve the stress condition, alleviate the conflict between the strength and plasticity of the die material, and have a great effect on edge-cutting die stripping, taizhou spinning board waste discharge, so as to significantly improve the service life of edge-cutting die.

According to the experience, suzhou lay die structure design should be focused on the edge of the cutting die width, cutting edge gradient and stripping slope factors.

It can be seen that the service life of the edge cutting die is significantly improved after adopting the second structure, and the service life of the M16mm bolt die prepared with W6Mo5Cr4V2Co5 and SKH51 steel is equivalent to that of the similar imported die made by SKH55 steel.
