Abstract：

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.
