基于有限元的板料冲裁模拟研究

Research on Blanking Simulation of Sheet Metal Based on Finite Element Method

使用DEFORM有限元软件进行了不同冲裁间隙的冲裁过程模拟研究,分析了板料冲裁变形过程及断裂分离过程,绘制了冲裁力、断面质量随冲裁间隙变化的趋势图。在此基础上,得到了冲裁间隙-冲裁功曲线变化图形,确定了合理冲裁间隙取值,具有一定的工程应用价值。

The DEFORM finite element software was used to simulate the blanking process of different blanking gaps;the blanking deformation process and the fracture separation process were analyzed, the trend of punching force and section quality with the blanking gap was drawn. On this basis, the change pattern of the blanking gap-punching power curve is obtained, and the value of reasonable blanking clearance is determined, which has certain engineering application value.
