| Abstract: | At first,draw step surface, binder wrap surface, draw bead, die round were designed according to the characteristics of auto panel, so that three dimensional die-face CAD model is obtained. Then the formability of die-face is improved by numerical simulations, which include FLD, changes of sheet metal thinkness and distribution of strain and stress. Based on the above die-face, 3D die structure is designed and manufactured by CNC. Finally the integration of CAD/CAE/CAM for auto panel drawing dies is fulfilled. |
