[0014] specific implementation plan
[0015] The method of the present invention is illustrated by taking the punched product with material as an example. figure 1 As shown, the structural features of this product are divided into two types: the narrow and long groove e in the middle part and the regular and irregular toothed f in the outer contour part. In the punching method, the feeding step of the punching strip is L, and L is the length M of the product plus the length N of the edge. When designing the mold, such as image 3 As shown, the narrow and long groove e is divided into two features, that is, feature a1 and feature a2. For regular and irregular tooth shapes f, starting from the requirements of mold processing technology, it is divided into seven features such as feature a3-feature a9. Among them, feature a5 is the part that needs to be cut off caused by the vertical edge (ie, process waste), and the remaining features a3, a4, a6-a9 are the parts that need to be...
