摘　　要：运用板料成形有限元软件,对磁力泵隔离套零件的充液拉深成形过程进行模拟,获得成形后的零件成形极限图(FLD)和侧壁厚度分布图,研究了在确定的压边力、凹凸模圆角半径和摩擦系数下,液室压力、压边间隙对零件成形质量的影响规律。研究表明,当液室压力为40 MPa时,侧壁厚度分布范围在0.932~1.027 mm之间;压边间隙为1.08 mm时,零件的侧壁厚度最大减薄率为8.8%;通过控制液室压力为40 MPa、压边间隙为1.08 mm时,试验件壁厚均匀、减薄率低,获得较佳的成形效果,试验结果也进一步验证了结论的有效性。The finite element software for sheet metal forming for was used to simulate the hydro-drawing process of magnetic pump isolation sleeve parts.The forming limit diagram(FLD)and the distribution diagram of side-wall thickness were obtained.The influence laws of chamber pressure and blank-holder clearance on the forming quality of parts were studied under the determined blank-holder force,round corner radius of die and punch and friction coefficient.The results show that when the chamber pressure is 40 MPa,the distribution range of side-wall thickness is 0.932-1.027 mm.When the blank-holder clearance is 1.08 mm,the maximum thinning rate of side-wall thickness for the formed part is 8.8%.When the chamber pressure is 40 MPa and the blank-holder clearance is 1.08 mm,the wall thickness of the test part is even,the thinning rate is low,and the better shaping effect is obtained.The validity of the conclusion is further verified by the test results.
