板材剪切加工时，因变形集中在狭小的区域内，变形过程复杂，冲裁力多采用近似的方法进行计算。斜刃冲裁时，变形过程更加复杂，对这方面的理论研究较少，文献［１］给出的剪切线为直线的斜刃冲裁力的计算式，不能普遍适用。而对圆形冲裁件的斜刃冲裁的研究，还几乎是个空... Sheet metal cutting processing, due to deformation concentrated in a narrow area, the deformation process is complex, the punching force more approximate method to calculate. When the oblique edge blanking, the deformation process is more complex, less theoretical research in this regard, the literature [1] gives the straight line tangent edge blanking force formula, can not be universally applicable. The circular blanking edge blanking blanking research, but also almost empty ...
