Abstract：

The aluminum alloy end-plate researched was a kind of typical part accompanied by end flange folding in the reverse direction, and defects such as winkles and cracks were extremely prone to occur during the forming process. According to the problems of wrinkles and poor forming accuracy in the forming process of end-plate, the mold structure was optimized to realize single-pass forming and improve the integrity and forming quality of products. Meanwhile, the appropriate blank shape was selected by the finite element analysis, which could eliminate the cracking problem during the forming process of products, and it was verified by test. The results show that compared to the traditional punch and die structure without die roof, the wrinkling of transition area in end-plate is effectively relieved by the optimized structure with die roof, and the maximum thickening rate is reduced to 6.7%. And the maximum thinning rate of transition area in end-plate was controlled to be 12.11% by adopting the blank with lug structure of R50 mm.
