摘　　要：介绍了三辊连轧管机的3种换辊型式,分析了三辊连轧管机的换辊动作过程,研究了三辊连轧管机的换辊设备结构。研究结果表明:三辊连轧管机目前有轴向换辊、单侧换辊和双侧换辊3种换辊型式;3种型式中轴向换辊的换辊时间相对较长;要提高换辊效率,实现快速换辊的三个关键点为传动轴的啮合控制、传动轴驱动回位及设备到位检测。In the article the three types of roll stand changeover of the 3-roll mandrel mill are described,and the roll changeover movement procedure is analyzed.The structure of the roll-stand changeover device of the said pipe mill is studied.As a result it is concluded that three roll-stand changeover types for the 3-roll mandrel mill are currently adopted,i.e.,the axial changeover,the lateral changeover and the bilateral changeover,among which the axial changeover takes relatively rather long time;and that the three key aspects related to enhancing roll-changing efficiency so as to realize fast roll-changing operation are control of the drive spindle engagement,driving-back of the drive spindle,and the device-inplace detection.
