AI Technical Summary

Technical Problem

Traditional cold stamping processes suffer from insufficient centering accuracy, excessively long mold changing time, and short mold life, making it difficult to meet the production demands for high precision and high efficiency.

Method used

A cold punching die with self-centering function was designed. The centering mechanism consists of fixed rollers and floating rollers. The workpiece is accurately positioned by rolling friction. The T-shaped slide structure facilitates quick replacement of the die.

Benefits of technology

It achieves high-precision self-centering and quick change of workpieces, improves production efficiency, reduces friction, avoids scratches on workpiece surfaces, and extends mold life.
