Abstract：

The springback of twice drawing was simulated for QT8812 engine oil-pan by ETA/Dynaform. The circle part of the lumbar and the deep box before and after trimming were analyzed，and the data collected from the typical characteristic location of the above were contrasted. The results show that the springback is associated of the characteristic of attach-die, when the attach-die during the stage of drawing is wore, the plastic deformation is more sufficient and the springback is lower, on the contrary, the springback is larger. The result shows that after twice drawing molding and trimming, the springback is very low，and the absolute size is less than permissible value 2mm.
