摘要：

某航空用不锈钢叶轮盘零件需要冲压加工该零件上均布的25对月牙孔，并满足相应的孔位置尺寸要求。根据叶轮盘的零件特征，确定了工件的冲裁方案。采用独特的模具定位方式，通过高精度分度盘、定位轴与轴销三者的配合，设计了一种月牙形孔手动分度冲裁模机构，实现了对该零件上25个均布的月牙形孔手动分度冲压加工。生产结果表明，该冲裁模结构设计合理、操作方便，冲压加工的工件尺寸完全符合图纸设计要求。

As a stainless steel impeller disk used for aviation, 25 crescent holes are uniformly distributed on stamping part, and the size requirements of the hole positions should be met. According to the aviation parts feature, the blanking workpiece positioning scheme was determined, through the use of unique position mode and the coordination of high precision index plate,positioning shaft and shaft pin,a blanking die mechanism of manual scalemark for crescent hole was designed to realize the stamping of 25 uniform crescent shape holes. Production results show that the stamping die structure design is reasonable and convenient to operation. The size of workpiece in stamping processing fully meets the requirements of design drawings.
