| Abstract: | Dynaform software is used to simulate and numerically analyze the drawing forming of the fender. Through the setting of related parameters such as sheet, tool, process and control parameters, the influence of blanking force, stamping speed and drawbead on the drawing of the fender is studied. The cracks, wrinkles and thinning of sheet metal during forming are predicted. According to the complexity of sheet metal deformation, the size and distribution of the drawbead resistance are set, the force state of the sheet material in the deformation zone is reasonably changed, and the processing quality in the actual stamping process is improved. |
