Research On The Mechanism Of Fine Blanking

Fine blanking technology has still been performed based on experience from its invention to this day. It is well known that the hydrostatic stress can be increased by the fine blanking facilities and die to improve the material plastic and to enhance the quality of sheared surface, the parameter of fine blanking in reality are feasible, but whether they are the most perfect or not. To answer the question, the corresponding relationship between the parameters of fine blanking technology and the hydrostatic stress in shear zone must be studied. The corresponding relationship between the parameters of fine blanking technology and the quality of fine blanking plane can be obtained visually. But most deformation of material in the material processing takes place with in a narrow zone and nearly no deformation is observed away from the narrow zone by experiment, naturally it is impossible to obtain the relationship between the parameters of...
