Abstract：

Based on the characteristics of stepper motor shell parts and the technical requirements of production, the multi-station progressive die was designed. First of all, the stepper motor shell parts were arranged in a single straight row, and the feeding distance adoptted coarse positioning of side edge and fine positioning of guide pin, with a feeding step of 57.35 mm, which made the process of popping up and moving to the next station for sheet more accurate. Secondly, the multi-station progressive die of stepper motor shell parts adopted a smooth discharge structure, which made the workpiece and scrap separate naturally and reduced labor costs. Finally, the multi-station progressive die of stepper motor shell parts was designed without empty stations,

which reduced the overall volume of die and the cost of die manufacturing. The production results show that the structure design of multi-station progressive die for stepper motor shell parts is reasonable, which has important reference significance for guiding the actual production of engineering. In addition, the material utilization ratio of die is as high as 85%, which saves material.
