Optimization of Structural Performance of Punching Tool under Impact Load
In this paper,CATIA 3D drawing software is used to design a punching tool and CrWMn alloy tool steel is used to manufacture a punching tool.The influence of blade angle on the impact resistance of punching tools and their fail-ure forms are studied.The stress simulation is conducted by ABAQUS,and experimental verification and microscopic mor-phology analysis are conducted.The results show that the stress concentration of the punching tool mainly occurred in the annular edge area,and an increase in the angle of the edge can significantly improve the impact resistance of the tool.The fracture failure areas of punching tools all appear in the annular edge area,with neat fracture surfaces and localized brittle fracture as the failure form.
