从薄壁管成型时带钢边缘的纵向拉伸变形及成型过程的稳定性方面推导出确定双层卷焊管成型区长度及成型倾角的解析式,为双层卷焊管成型机组的设计及孔型设计提供了理论依据。
From the thin-walled tube forming the edge of the strip longitudinal tensile deformation and the stability of the forming process deduced to determine the double-roll tube forming zone length and forming inclination of the analytical model for double-roll tube forming unit design and hole Design provides a theoretical basis.
