拉深筋位置对曲面翻边成形回弹影响的研究

Study on the influence of drawbead position on springback in curved flanging

利用Dynaform软件在一次翻边工艺中设置拉深筋来完成曲面翻边类零件的成形,通过数值模拟与试验相结合的方式,研究拉深筋在凹模上4处不同的位置对曲面翻边类零件的成形回弹影响,得到可以控制制件壁厚减薄率回弹的最佳拉深筋位置在2和3之间,在实际生产中对提高类似零件的成形质量有一定的指导作用。

The flanging process of a curved flanging part was finished through setting an drawbead by Dynaform software. Through the combination of numerical simulation and ex- periment, the influence of the drawbeads in different four locations of concave die on the springback of curved flanging parts was researched.
