| Abstract: | The paper discussed the principles and characteristics of the opposed die shearing. In order to compare the fine-blanking parts with the blanking parts, we designed and had produced two kinds of dies for experiments, one for fine-blanking parts and the other one for the blanking parts. By working on the micro-predicament metals flow line and analyzing the degree of hardness of one fine-blanking part cross section, the mechanism of the opposed die shearing was studied. At last, based on the research of the key parameters of the opposed die shearing mold, the paper designed one die for some cams. |
