| 摘 要： | 针对精冲三维数值模拟的局限性,采用有限元软件Deform-3D建立摩擦片背板的三维精冲模型。根据Normalized Cockroft＆Latham断裂准则,分析了成形过程中的静水应力、金属速度流动分布和发展趋势。通过数值模拟获得最佳冲裁间隙值为厚度的0.6%,为提高精冲件质量提供了依据。

| Abstract: | Due to the limitation of 2D simulation in fine blanking,finite element software DEFORM-3D was used to simulate the 3D model of Back Plate.In this article the Normalized Cockroft & Latham fracture criterion was chosen to simulate the blanking process.The distribution and developing trend of the hydrostatic stress and velocity in the fine blanking process are predicted.It shows that the ideal blanking clearance value is 0.6% of the material thickness.The results indicate that FE numerical simulation could eff... |
