摘　　要：介绍了一种数控冲床中旋转冲头装置的结构与工作原理,并且对旋转装置的定位提出了一套简单可行的方案。采用ANSYS软件对数控冲床的旋转冲头装置进行有限元分析与计算。由静力学分析可知,极限条件下的变形量为0.013728mm,对系统的影响可忽略不计。根据模态分析的前4阶固有频率振型图可确定振动变形主要发生在下模座安装凹模的凹槽位置处,提高此处的材料性能和增加此处的半径,可有效提高旋转冲头的性能。The structure and working principle of revolving punch were introduced and the method of positioning accu- racy was suggested. The revolving punch was analyzed and calculated based on ANSYS software of finite element anal- ysis. The statics analysis shows that the deformation under limit condition is O. 013728 ram, 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 increas- ing the radius of this location can effectively improve the performance of the rotating punch.
