斜刃剪切力计算公式适用范围的探讨

Discussion on a Range of Application of the Calculating Formula of Shearing Force with Die of Inclined Edge

在现有的与冲压有关的参考资料中 ,对斜刃剪切时剪切力的计算公式都没有限定适用范围 ,很容易引起误解 ,文中从不同角度分析并探讨了斜刃剪切时 ,斜刃倾角α取不同值时剪切力的计算办法 。

In existent reference material on stamping,a range of application of the calulating formula of shearing force of die of inclined edge is not limited.This gives rise to misunderstanding very easily.Now this paper from different point of view justly analyses and discusses the callculation method for shearing force with different rake angle a of inclined edge,so it has very practical and important significant.
