摘要：
Continuous multipoint forming method(CMFM) was introduced simply. The key rollers of continuous multipoint forming device(CMFD) were studied in different disposals and different drives. The drive of three rollers at two sides was felicitous realized, and the CMFD was developed. The process of roll bending was discussed. The results showed that one-step forming is adopt on mini deformation, but when the press displacement of top roller exceeds stated value, the procedure can't be continued, the multi-step forming is advantaged of inducing sheet metal deformed, eliminates the sides winkle, and reduces the spring back with each mini deformation.
