Abstract：

The structural characteristics and stamping process of a micro motor fan blade with the height of 7.5 mm, the maximum shape size of Φ44 mm and eight equal parts around 90 ° curved blades were analyzed, and the layout design of three sets of parts was developed and optimized. Then, the fan blade was produced by riveting base and blade into one assembly and it was replaced by a new process of first cutting and then bending into integration. Therefore, the design project of multi-position progressive die was one-out with one-arrange proposal. Firstly, it was introduced that the whole structure of die and the compound technology of die structure design including cutting and bending, and then the compound technology was elaborated in details. The production practice shows that the cutting and bending processes are designed by the punch and die gradually separating from the plate and then bending into 90 °. Therefore, the punching is a safe and reliable operation, which can greatly reduce cost, and improve material utilization and productivity.
