对冷冲压凸模热处理工艺的改进

Improvement of heat treatment processing on cold ramming raised mold

以Cr12MoV冷冲压凸模为例,介绍热处理工艺的改进有利于提高凸模的使用寿命,特别是刃口改为采用等温淬火后,可以有效地保证凸模整体的强韧性和刃口部分的耐磨性,使模具的使用寿命提高了8倍。

This article, with the Cr12MoV cold ramming raised mold as an example, improves heat treatment processing to prolong the service life of raised mold by quenching the cutting edge with uniform temperature, which enhances strength and obdurability of the raised mold as well as the resistance to wear of cutting edge, thus prolongs the mold service life by eight times.
