摘　　要：以某种型号冲压平皮带轮为例,在分析了该零件加工难点后,提出了3种可行的成形方案。在分析这3种方案优劣后,因方案Ⅲ工序少,复合度高,且能保证工件精度和同轴度,所以根据方案Ⅲ给出了冲压模具结构图。该模具结构简单、减少了工序,提高了效率。Taking a particular flat belt pulley as an example, the forming difficulties of the part were analyzed, and three feasible stamping processes were put forward. Through comparison, process Ⅲ was selected because it had less process steps, more compound processes, and it also could ensure the precision and coaxiality of the part. The stamping die structure was presented according to process Ⅲ. The die was very simple in structure and could reduce process steps and improve efficiency.
