Abstract：

For stamping parts in clutch, the pre-cut blanking depth, blanking clearance and blanking speed were selected as the influencing factors, and the length of bright region was used as the evaluation index. Then, the three-level and four-factor orthogonal test was designed, and the quality of cross section for pre-cut blanking of sheet metal under different blanking parameters was simulated by Deform-2D. The range analysis of orthogonal test shows that the influence sequence of technological parameters on the quality of cross section for pre-cut blanking is blanking clearance > blanking speed > pre-cut blanking depth. Furthermore, the optimum technological scheme for pre-cut blanking of sheet metal is the pre-cut blanking depth of 0.15 mm, the blanking clearance of 8%t, the blanking speed of 15 mm·s-1 and the length of bright region of 0.83 mm. In addition, the blanking experiment was conducted by stamping progressive die. And the experiment value of length of bright region is 0.738 mm. Thus, the relative error between experimental value and simulation value is 12.5%, which provides an important guidance for the actual production of enterprise.
