摘要：

通过对卷曲式JCOE制管过程芯轴卷曲成形时钢板回弹量的理论分析计算,提出了根据回弹量确定成形芯轴直径的方法,所得方法对卷曲式JCOE钢管的成形工艺具有指导意义。

By theoretically analyzing and calculating spring back during pipe forming by the coiled-type JCOE process,a method based on spring back was submitted to decide the diameter of mandril.The acquired method has a directive meaning for manufacturing the coiled-type of JCOE steel pipe.
