摘要：

针对断路保护器定位板自动铆轴的生产需求，设计了一种能够装配在级进模具中的销钉自动送料机构。通过分析断路保护器定位板的加工工序，获得设计自动送料机所需要的相关参数与技术要求，并拟定设计思路与方案；将自动送料机的设计分为下料机构设计和平移送料机构的设计，对两部分的结构设计进行详细说明，并阐述其工作原理；最后，将断路保护器销钉自动送料机构装配在冲铆级进模具中。实际生产表明，自动送料机构设计合理，省去了人工传送销钉的过程，避免了因人工失误而导致的次品，产品合格率提高了近12%。

For the production demand of automatic riveting shaft in the positioning plate of circuit breaker protector, an automatic feeding mechanism of pin assembled in the progressive die was designed. Then, through the analysis of processing procedure for positioning plate of circuit breaker protector, the relevant parameters and technical requirements for the design of automatic feeding mechanism were obtained, and the design idea and scheme were proposed. Furthermore, the design of automatic feeding mechanism was mainly divided into the designs of blanking and translation feeding mechanisms, and the structure designs of two parts and their working principles were described in detail. Finally, the automatic

feeding mechanism of pin for circuit breaker protector was assembled in the punching and riveting progressive die. The actual production shows that the design of the automatic feeding mechanism is reasonable, the process of manual pin feeding is omitted, the defective products caused by manual mistake are avoided, and the qualification rate of product is increased by nearly 12%.
