| 摘 要： | 倾斜板料冲裁的冲裁力计算是一个尚待研究的课题。本文对倾斜板料圆孔冲裁的冲裁过程进行了探讨，将其分为板料包容冲头和板料不包容冲头两种类型和三个冲裁阶段，导出了每种类型各冲裁阶段冲裁力的计算公式，分析了冲裁力随行程的变化规律，研究了最大冲裁力和板料厚度、圆孔直径、板料倾斜角度的关系，获得了一些有价值的结论。

| Abstract: | The blanking force calculation of blanking through inclined sheet metal is an outstuding subject. Inthis paper, the blanking process of blanking hole through inclined sheet is approached which consists of threestages and consists of two types --the type of harbouring punch by sheet and the type of non--harbouringpunch by sheet, the calculatino formulas of blanking forces in all blanking stages about the types are derived, the force changing rules along with punch travel are analysed, the effects of sheet metal thickness, hole diameter and inclined angle of sheet on the maximum force are studied, and some valued conclusions are obtained. |
