Abstract：

The structure and working principle of revolving punch were introduced and the method of positioning accuracy was suggested. The revolving punch was analyzed and calculated based on ANSYS software of finite element analysis. The statics analysis shows that the deformation under limit condition is 0.013728mm, which can be neglected. Based on the modal analysis of the first four order natural frequency vibration mode diagram, the vibration deformation occurred in groove position place of the concave die can be determined. Improving the material performance and increasing the radius of this location can effectively improve the performance of the rotating punch.
