| Abstract: | The drawbead force requirements are calculated for the large melon-shaped part.The drawing process is simulated by using the professional sheet metal forming software ETA/DYNAFORM.It is analyzed that how the factors,including the shape of binder surface,the dimensions and distribution of drawbeads,affect the forming quality of the part.And then,the design ideas of binder surface and drawbead for the typical mouth-curved-edge part die design are obtained. |
