    摘要:

    通過(guò)分析基于連續(xù)多點(diǎn)調(diào)形方法的三維曲面卷板成形原理，對(duì)卷板成形裝置關(guān)鍵件柔性輥的不同布置和驅(qū)動(dòng)方式進(jìn)行了研究,。確立了三輥布置雙端驅(qū)動(dòng)的方式,，設(shè)計(jì)了三維曲面卷板成形裝置,。對(duì)卷板成形工藝進(jìn)行分析,，探討了不同的成形工藝過(guò)程,。結(jié)果表明：一步成形,，在小變形量的情況下適用,，當(dāng)上輥的下壓量超出一定值時(shí)，無(wú)法成形,；分步成形法,，以小的下壓量逐漸誘導(dǎo)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.
