Abstract：

The quantitative relationship of trapeziform drawbead structure parameters and drawbead restraining force was studied by the regression orthogonal experiment by using the drawbead test system. The linear regression equation of the relationship between trapeziform drawbead structure parameters and restraining force was established. The F test for significance of the regression equation and partial regression coefficient was carried out to verify the accuracy of the regression equation. The influence law of trapeziform drawbead structure on the restraining force was analyzed. The radius of convex rib round corner and groove have significant effect on the restraining force, while the influence of trapeziform drawbead height is not significant. The generality of the regression equation was ensured by replacing the experimental factors in the regression equation by the ratio of actual values of structural parameters to sheet thickness t. Through the regression equation, the drawbead restraining force when the sheet passed through the drawbead was predicted according to trapeziform drawbead structure parameters, which provided reliable experiment data for the design of stamping die drawbead.
