本发明所谈到的是一种带皮尔格孔型的新型轧管机。这种轧机能轧制出管壁更加精确和均匀的钢管,特别是薄壁钢管;同时可在不过份增加轧管机载荷及损伤钢管的情况下提高生产率。这种轧机还能提高产品质量,保证航空工业和各种科学事业对许多特殊用途的薄壁钢管所要求的均匀性和强度。这种轧机的工作主要靠钢管支撑心棒上下特殊排列的工作辊来完成。在驱动这些工作辊背向心棒末端转动的同时,这些工作辊也在行星轨道上向心棒末端 The present invention relates to a new type of pipe rolling mill with Pilger type. The mill can roll more precise and uniform steel tubes, especially thin-walled tubes, while increasing productivity without excessive tube mill load and tube damage. Such mills also improve product quality and ensure the uniformity and strength required by many aviation industries and scientific applications for many special-purpose thin-walled tubes. The work of this type of rolling mill is mainly supported by a special work roll with steel tubes supporting the mandrel up and down. While driving these work rolls to rotate toward the end of the mandrel, these work rolls also move in the direction of the orbital axis towards the end of the mandrel
