[0002] Ring rolling machine generally has driving roller, driven roller, guide roller, control roller and other rollers. When working, the heated ring blank is sleeved on the driven roller, the driving roller rotates with the ring blank on one side, and the other side relies on oil pressure to make radial feeding, so that the blank is stretched under pressure, the wall thickness is reduced, and the inner and outer diameters are increased at the same time. The guide roller always relies on the workpiece, and the rest of the rollers rotate by friction. When the outer diameter of the workpiece reaches the required size, the workpiece contacts the control roller to send a signal to make the driving roller return, and the hole expansion ends.
