Abstract：

The processing schemes and layout schemes were formulated by analyzing the locating plate structure of breaker protector, and a four-axis punching-riveting progressive die was designed with guide mechanism, positioning mechanism, punching mechanism and riveting mechanism, etc. In the structural optimization, the positioning was set up by pin vertical guide block and the pin upper limit post to ensure the verticality and the penetration depth of the pin, and the accuracy of parts was improved. In the design method, the double-row guide column was chosen as the guide system, the reduced diameter section of the loaded strip was used together to reduce the position error of the strip forward. In addition, the production efficiency was greatly improved by using the four-axis simultaneous rivets. The actual production proves that it is reasonable to combine with punching and riveting, which not only saves the manual rivet process to lower the labor intensity of workers and reduce cost by nearly 60%, but also improves product yield from 80% to almost 100%, and production efficiency by nearly 50%.
