【Abstract】 According to the design characteristics of modern automobile panel die, the technologies of feature parametrization design and feature group optimization assembly are used to design the die-face of panel drawing die. The die-face of drawing die is proved to be qualified by the numerical simulation of sheet metal forming. Finally, based on the 3D mathematical model of the drawing die die-face, the die structure are modeled by the ways of design for assembly and top-down design, and the case-based design for the panel’ s die structure are realized.更多还原
