摘要：

分析了端座零件的冲压成形工艺，介绍了零件的排样设计、模具的总体结构及关键工位的设计。条料采用侧刃与导正销定位，单侧载体排样，为提高弯曲精度增加了预弯工序。模具设计采用内外精密导向机构，关键零件设计成镶块式结构，既保证了工作零件的强度，又便于制造。配置的误送检测机构能有效防止条料误送，压印调整机构能有效控制条料的偏摆。实践表明，排样方案可行，模具结构合理，工作平稳，使用方便，制件质量稳定，生产效率高。

The stamping technology of terminal seat was analysed．Layout design，total structure of the die and design of the key station were introduced．Side blade and guide pin were adopt to locate the strip，and unilateral carrier was adopt. The pre-bending process was used to improve the accuracy of bending. The internal and external precision guide mechanism was adopted in the die，and the key parts were designed as inserts，which ensure the parts with high strength and being manufactured easily. Miscarriage detection mechanism was provided to avoid misdirected. The twist of strip was controlled notable by stamp adjusting mechanism. The practice shows that the layout scheme is feasible, the die structure is reasonable, the die works smoothly and operates conveniently，and the parts have stable quality and high production efficiency.
