研制比较完善和生产率较高的新型冷轧管机,要求轧机的所有部件都很完善。工作机架是冷轧管机的主要部件之一,完善工作机架的工艺和操作性能非常必要,因为传动轧辊的齿轮-齿条的加工制造既费时又复杂,而且使用中磨损严重,导致间隙逐渐增大和动载荷增加,从而使成品管材质量下降。众所周知,由于自然轧制半径与实际轧制半径的不一致而引起的强制性轧制过程对轴向力会产生很大影响。很大的轴向力将会导致工艺故障,并在很大程度上限制了轧机的工艺与操作性能。乌拉尔工学院与第一乌拉尔新钢管厂共同研制成功一种冷轧管机的工作机架新结构。对这种新结构进行了工业性试验,并对机架中轧 Developed relatively perfect and high productivity of new cold-rolled pipe machine, requiring all parts of the mill are perfect. Work racks are one of the main components of cold rolling mills. It is necessary to improve the workmanship and operability of the work racks because the gear-rack manufacture of the drive rollers is both time-consuming and complicated, Gradually increased and dynamic load increases, so that the quality of finished pipe decreased. It is well known that the forced rolling process due to the discrepancy between the natural rolling radius and the actual rolling radius has a great influence on the axial force. Large axial forces will lead to process failures and to a large extent limit the mill’s process and operational performance. Ural Institute of Technology and the first Ural new steel pipe plant jointly developed a successful cold-rolled tube machine work rack structure. This new structure was tested industrially and rolled on the stand
