| 中文摘要: |
| 针对一款汽车接插件的L形插针制件头、尾部材料厚度不一致的特点，在分析其成形工艺基础上，制定了3种结构方案。经对比分析，确定采用27个工位级进模成形制件，通过4次连续拍打的方法实现厚料局部变薄，并确定了排样方案。实际生产试验表明，L形插针多工位级进模结构设计合理，在技术上，解决了插头尾部材料厚度连续渐变的难题，可满足制件大批量生产的需要。 |
| 英文摘要: |
| According to the characteristics of the L shape pin head parts and the tail material whose thickness is inconsistent of a connector for automotive, on the basis of analyzing the forming process, three structural schemes are developed. By comparison and analysis, the 27 position progressive die parts are determined, and the local thinning of the thick material is realized by the method of four successive beating. And the layout scheme is determined. Actual production test shows that the design of the L-shaped multi-position progressive die is reasonable. It solves the problem of continuous gradient of the thickness of the plug tail material in technology. It meets the needs of large volume production. |
