    摘要:

    通過分析基于連續(xù)多點調形方法的三維曲面卷板成形原理,，對卷板成形裝置關鍵件柔性輥的不同布置和驅動方式進行了研究。確立了三輥布置雙端驅動的方式,，設計了三維曲面卷板成形裝置,。對卷板成形工藝進行分析,，探討了不同的成形工藝過程,。結果表明：一步成形，在小變形量的情況下適用,，當上輥的下壓量超出一定值時,，無法成形；分步成形法,，以小的下壓量逐漸誘導板材變形,，可以消除板材邊緣皺褶，減小回彈,，有利于板材成形,。

    Abstract:

    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.
