盖板链条片成形工艺优化与模具设计

Optimization of forming process and design of die for cover plate chain piece

介绍了盖板链条片的原成形工艺,为提高链条片质量,从材料的选择到工序的改进等方面对链条片的成形工艺进行了优化。将切削加工中拉孔的方法运用到链条片孔的精整冲压加工中,提高了链条片上冲裁孔的断面质量,满足了零件质量要求。详细介绍了拉孔整修凸模的设计,为探索使用拉孔方法提高冲压件的断面质量提供了技术依据。

The forming process of cover plate chain piece was presented. In order to opti- mize the forming process and quality of chain pieces, some aspects such as material selec- tion and improvement of process, etc were adopted. The broaching method in machining was used in the finishing stamping of chain piece hole to improve the section quality and satisfy the requirements for the parts. Then the design of punch for broaching recondition was introduced.
