Abstract：

A forming process scheme of dustpan-shaped thin-walled part for 2A16 aluminum alloy was determined, and software DYNAFORM was used for finite element simulation to study the problems affecting the product quality such as cracks and wrinkles during the forming process. Then, for aluminum alloy dustpan-shaped thin-walled part, the punch-die clearance-maximum thinning rate and thickening rate curves blank holder force-maximum thinning rate curve, and blank holder force-maximum thickening rate curve were obtained by simulation analysis at different punch-die clearances and blank holder forces, and by comparing the forming quality of workpiece with different blank sizes, the optimal process parameters were determined as the blank size of 237.42 mm×319.24 mm, the punch-die clearance of 1.75 mm and the blank holder force of 50 kN. Furthermore, compared with single piece deep drawing, the material utilization rate was increased by 48.498%, and the product processing efficiency was doubled by paired deep drawing. Finally, through the deep drawing experiment, the rationality of the paired deep drawing scheme and the process parameters were verified, which provided technical reference for the forming of dustpan-shaped thin-wall parts.
