数控冲床加工框类钣金件过程中零件变形的问题分析和研究

摘要

分析了数控冲床加工典型钣金件的冲裁过程,阐述了冲裁变形的产生机理.通过改进编程方法和冲压过程中压紧板料的方法来减小冲裁变形量,并在生产中取得了良好的效果.%The punching process of typical sheet metal part by CNC punch press has been analyzed in the text. The reasons of deformation during blanking process have been illustrated. The punch deformation has been decreased by improving the programming method and clamping method during punching process. Good effects have been gained in the production.
