AI Technical Summary

Technical Problem

The rectangular mesh of existing radiator mesh plates is prone to stress concentration at the corners during punching, resulting in quality defects such as burrs and flanging, as well as low forming quality and precision, and low production efficiency.

Method used

A processing mold is used, which sets a corner cutting edge at the corner of the punch to first partially or completely cut off the stress concentration point of the mesh during punching, and then the punching is completed by the cutting edge at the edge of the punch. Combined with the limiting guide block and the reinforcing guide sleeve, the positioning accuracy and guiding accuracy are ensured.

Benefits of technology

It improves the defects of flanges and burrs at the corners when punching rectangular mesh, improves forming quality and precision, reduces production time, and increases production efficiency.
