摘要

生产中发现SUS304/Al1050/SUS430复合板拉深成形中与轧制方向成90°方向的筒壁存在起皱的现象。为了解决起皱的问题,首先测量了各层板的力学数据并导入到Dynaform中,采用正交试验方法研究了凹模圆角半径、板料直径、摩擦系数和压边力等因素对复合板筒壁起皱的影响。然后根据优化模拟结果设计出防止筒壁起皱的最佳工艺参数,同时采用增加拉延筋的方法解决筒壁起皱。试验结果表明,复合板的最优工艺参数组合为:凹模圆角半径14 mm,板料直径355 mm,摩擦系数0.2,压边力170 kN。在此工艺下,增加拉延筋,筒壁起皱得到解决,工件质量得到提高。
        In the process of direction at SUS304/Al1050/SUS430 cladding sheet with rolling deep drawing production, it was found that there is a wrinkling phenomenon the cylinder wall 90°. In order to solve the wrinkling problem, the mechanical data of each layer sheet were measured and introduced into Dynaform. The effects of die radius, sheet diameter, friction coefficient and blank holder force on the wrinkling of the cladding sheet were studied by orthogonal test. Then according to the optimized simulation results, the optimum technological parameters for preventinf wrinkling of the cylinder wall were designed, and the method of adding brake bead to solve the wrinkling of the cylinder wall was adopted at the same time. The experimental results show that the optimum technological parameters of cladding sheet are die radius of 14 mm, sheet diameter of 355 mm, friction coefficient of 0.2, and blank holder force of 170 kN. Under this process, the wrinkling of the cylinder wall is solved by adding brake beads, and the quality of the workpiece is improved.
