锌基合金是一种新的模具材料,用它制造冷冲模,具有周期短、成本低、冲件优良等特点,尤其在制件批量少、任务急的情况下,更能显示其先进性。现将我厂应用锌基合金冲裁模的体会介绍如下:一、有关“单向裂纹”机理的探讨普通钢制冲裁模是根据“两向裂纹及扩展相迎”的冲裁机理进行设计和制造的。而锌基合金冲裁模是根据“单向裂纹
Zinc-based alloy is a new kind of mold material, which can be used to make cold die. It has the characteristics of short cycle, low cost and excellent quality of red parts. Especially in the case of small parts and urgent tasks, the advanced performance of zinc-based alloy is better. Now I plant the application of zinc-based alloy blanking die experience described below: First, the ”one-way crack “ mechanism of discussion Ordinary steel blanking die is based on ”two-way crack and extended welcome“ Cutting mechanism for the design and manufacture. The zinc-based alloy blanking die is based on ”one-way crack
