摘　　要：采用有限元方法对新型锥形食品罐的成形工艺进行优化,解决实际生产过程中出现的盖边法兰褶皱问题,并对落料预成形进行分析。结果表明,采用含加强筋的结构及合理的压边力能有效减轻盖边法兰褶皱现象,在保证落料尺寸足够的前提下,生产的零件应尽可能使法兰边规整。In order to avoid wrinkling on the flange in the production of a new conical food can, the forming process of the part was optimized by finite element method, and the blanking preforming was analyzed. The results showed that the rib design and the reasonable blank holder force could effectively reduce the wrinkles. Under the premise of ensuring the sufficient size of blanking, the flange boundary of the parts should be as regular as possible.
