摘　　要：分析了小孔冲裁模具在冲裁过程中凸模的受力情况,得出在冲裁过程中,小凸模在承受冲裁力的同时还会承受一个偏载力,并进而分析了小凸模的变形特点,最后推导出小凸模长度尺寸优化校核的计算公式,优化了小孔凸模结构尺寸。该公式为小凸模长度尺寸优化设计提供了一种依据。Analyzed the holes in the process of blanking die in blanking force of the punch.It is concluded that in the process of blanking, have a small punch blanking force and a lateral. Analyses the deformation characteristics of small punch,finally deduces small punch length size optimization and checking calculation formula, optimized the small hole convex mold structure size. The formula for the small punch length provides a basis for optimization design.
