| 摘 要： | 对不锈钢管件无模拉伸变形时壁厚变化进行了实验研究 ,分析了不锈钢管件无模拉伸时壁厚变化的影响因素及影响规律。确定了不锈钢管件无模拉伸时壁厚变化经验公式。实验结果发现 ,不锈钢管件无模拉伸时 ,壁厚变化tf/t0 与Dif/Di,D0 f/D0 ,1-RS的值成正比 ,即 :tf/t0 =k1Dif/D0 =k2 D0 f/D0 =k3 1-RS。对于薄壁不锈钢管件 (当t0 /D0 <0 1)无模拉伸时 ,k1=k2 =k3 =1。

| Abstract: | Variation of wall thickness during tube dieless drawing has been studied by experiment.It has been put forward that the variation of wall thickness is in directly proportion to outer|diameter,inter|diameter and (1-R S) 1/2 (Rs|sectional reduction ratio of tube).With the increasing width of deformation,the value of variation of wall thickness and the derivative of wall thickness variation( t f/t 0) to width of deformation are both reduced. |
