摘要： An inner roller used for roll forming pipe elements has a flange extending radially from a body. The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming.

摘要翻译： 用于辊成型管元件的内辊具有从主体径向延伸的凸缘。 凸缘具有分成环形表面部分的表面。 表面部分具有相对于内辊的旋转轴线测量的取向角度。 距离主体更远的表面部分的取向角具有比靠近身体的表面部分更大的取向角，以减轻在轧制成形期间管件和法兰之间的不利的摩擦效应。
