Abstract：

The precision requirement of fine blanking die is very high, and the die needs to be disassembled several times for the research on die wear during the experiment, which influences the assembly accuracy and the wear test results. Therefore, based on the wear analysis of fine blanking die, a method was put forward to study the wear of fine blanking die by designing blank extrusion die. Comparing the blank extrusion die with the common wear tester in the market, it was found that the blank extrusion die was closer to the wear condition of fine blanking die, and the measured data were more abundant. Furthermore, the forces acting on the blank extrusion die and fine blanking die were simulated and compared by the finite element simulation software. The simulation results show that their stress distributions during the forming process are approximately the same in a certain extrusion section ratio, and the blank extrusion experiment can be equivalently used to study the die wear in fine blanking. On the basis of above research, a blank extrusion die with holder was designed, which can be used to further study die wear mechanism.
