为研究和掌握新的经济型材生产,车里亚宾斯克工学院设计并制造了一台轧制异型和周期型材的四辊孔型轧机。轧机有机架和传动部分。孔型由四个轧辊组成,四个轧辊的中心线在同一个平面内。四个工作轧辊组装在一个可更换的框架内,并进行调整(图1)。在组装和调整孔型之后,它们被装在轧机机架中。通过四个元柱齿轮的减速机和分配箱将轧制扭矩传递给所有工作轧辊,(每个减速机的输出轴通 In order to study and master the production of new economical profiles, Chelyabinsk Institute of Technology designed and manufactured a four-pass pass rolling mill for profiled and periodic profiles. Rolling mill has rack and transmission parts. The pass consists of four rolls with the centerline of the four rolls in the same plane. Four work rolls are assembled in a replaceable frame and adjusted (Figure 1). After the holes are assembled and adjusted, they are installed in the roll stand. Through the four column gear reducer and distribution box will be delivered to all the work roll rolling torque, (each reducer output shaft through
