After the workpiece 8 is in place, the mandrel component 3 adjusts the vertical height by using the vertical guide rail 31, the oil cylinder 33 is started, the piston rod 33a extends out, and the mandrel 34 is sent into an inner hole of the workpiece 8; the main cylinder 51 of the support wheel assembly 5 is then operated to lower the main slide 52 with the support wheel 53 and bring the support wheel 53 into supporting contact with the mandrel 34. As shown in fig. 15, during cold rolling, the supporting wheel 53 provides a downward force, the rolling wheel 22 is driven by the reduction motor 21 to rotate clockwise, the rolling wheel 22 (as an outer die, the outer circular surface of the rolling wheel 22 has a profiled groove of the workpiece profile) contacts the outer surface of the workpiece 8, the mandrel 34 (as an inner die, the outer circular surface of the mandrel 34 also has a profiled groove of the workpiece profile) contacts the inner surface of the workpiece 8, the mandrel 34 performs counterclockwise driven rotation, the mandrel 34 continuously leans against the rolling wheel 22 under the pushing of the supporting wheel 53, so that the wall thickness of the workpiece 8 is reduced, the diameter of the workpiece 8 is increased, the profiled groove is mapped on the workpiece 8, and the cold rolling of the workpiece 8 is completed; the workpiece 8 after cold rolling is completely fed from the feeding chute 62 (the workpiece 8 to be processed next is pushed into the processing area, and the workpiece whose processing is completed in the processing area is pushed into the feeding chute 62). The feeding and discharging of the workpiece 8 are automatically completed by the feeding and discharging mechanism, and the automation degree is high.
