摘要
主要研究了铝合金板材V形弯曲回弹角与弯曲角、相对弯曲半径之间的关系,分析了宽板弯曲和窄板弯曲回弹角的差异。结果表明,在V形弯曲中铝合金板材的弯曲回弹角随弯曲角度数的增加而减小,随相对弯曲半径的增加而增加;厚板弯曲的回弹角明显小于薄板弯曲的回弹角,而板材的宽度对其回弹角则无明显影响。
The relationship of springbaek angle with bending angle and relate bending radius was investigated. The difference of spfingbaek angle between wide sheet and narrow sheet was analyzed. The results indicated that the spfingback angle decreased with increase of the bending angle and decrease of the relative bending radius. And the spfingback angle of thick sheet was obviously larger than that of thin sheet, on the other hand, it was not influenced clearly hy the sheet width.
