我厂在制造冷冲切模具的生产过程中,在热处理方面,对于减少模具淬火变形取得了一些经验,现将现场经验介绍于下,供兄弟厂参考。一、模具钢材的选择我厂制造冷冲模具所用的钢材为铬钨锰钢,因为这种钢材不仅具有良好的淬透性,而且淬火后所产生的变形较小,适合于制造几何形状复杂的模具。 I plant in the manufacture of cold punching die in the production process, in the heat treatment, to reduce the mold quenching deformation has made some experience, the field experience will now be introduced in the next, for reference brotherhood. First, the choice of mold steel Die made of cold stamping die used in our factory for the chromium tungsten manganese steel, because this steel not only has good hardenability, and deformation generated after quenching smaller, suitable for the manufacture of complex geometric shapes Mold.
