本文对TIOA钢制冲孔模使用过程中的失效情况进行了分析。并对改用Cr12MoV钢替代TIOA钢制冲孔模及采用的热处理方法作了说明。实践证明,选用CrMoV钢经化学气相沉积碳化钛处理制作冷冲孔模是提高使用寿命,获得较大经济效益的有效措施。
This paper analyzes the failure of TIOA steel punching die during its use. And the use of Cr12MoV instead of steel TIOA punching die and the use of heat treatment methods are described. Practice has proved that the selection of CrMoV steel by chemical vapor deposition of titanium carbide processing cold punching die is to improve service life and obtain greater economic benefits of effective measures.
