How to solve the problem of needle breakage of precision stamping parts? 'Hardware'

In daily life, precision stamping products are widely used in connectors, micro motors, acoustic components, sensors, automotive electronics, new energy, medical electronics, smart homes, diodes and IC packaging industries. During production, the punching needle of the precision stamping parts often breaks. Today, let the hardware tell you how to solve this problem. The solutions for the needle breakage of precision stamping parts are: choose the raw materials of good manufacturers. The needle hanger should retain the natural R angle, not too deep or too large, generally R is between 0.5-1.0. According to the actual demand of the punching needle material, the hardness is strictly controlled within its tolerance. The punching needle hangs the table for annealing. If the punching needle of the stamping die is 62-64 degrees, annealing the hanging table to between 48-50. In this way, it can also avoid the occurrence of punching needle breakage of precision stamping parts.
