3、目前都采用连续模结构冲压完成。并且介绍了由于不锈钢材料特性,模具成型元件的材料选择和热处理要求。本文通过日常工作中以及从同事、社会同行处收集、总结,然后系统整理出不锈钢弹片模具设计的要点,几乎涵盖了此类模具设计的主要经验、技巧,便于后来者参考。 也作为一个设计手册类的资料,供设计时参考。由于技术所限以及研究条件所限,本文还比较肤浅,对于一些关键的问题没有作很深入的研究,也没有很详尽的数据。以及一些新工艺也没有进行深入探讨。诸多不足之处还请指导老师多多包涵,并且会在以后的工作中进一步深入研究,并加以完善。关键词:连续模、冲头、凹模、不锈钢 A tractate about follow mold
