摘要
此文提出了内螺纹变截面铜管分段拉仲一次成形新工艺,并就工艺因素对该管拉伸成形的影响进行了试验研究,从而为合理制订成形工艺提供了依据。
The new forming technique is presenteel in this paper that Variee] section copper tube with spiral internal ribs is produced in a drawing pass by using empty sinking or plug drawing on different parts of the tube,and the influence of technological conditions on this tube drawing is investiguted. So the resarched results can be applied to make correctly drawing technique of the tube.
