摘要
通过分析零件连接块的圆孔冲裁特点,将原钻孔工艺改为冲孔工艺,设计了一副滑块式防胀边深孔冲模。实践证明,模具结构合理、冲压过程安全平稳,零件质量稳定,可为类似零件的冲孔工艺提供参考。
Based on analysis of the hole blanking characteristic of a link block, the original drilling process was substituted by piercing process and a slide block type deep hole blanking die with anti edge expansion structure was developed.
