[0032] Preferably, the lower layer of the cross table 4 is provided with a third driving assembly 10 for driving the upper layer of the cross table 4 to move. Exemplarily, the third driving assembly 10 can also adopt existing drivers such as ball screw and servo motor to drive the upper layer of the cross table 4 to move, which will not be described here.

[0033] The rolling working process of the rolling machine is as follows: Firstly, the workpiece to be processed is arranged in the hopper 8 in parallel, the top pin of the clamping mechanism 3 is retracted to the loosening position of the workpiece to be processed, the adjusting seat 20 on the adjusting assembly is lowered, the rolling wheel 14 is in the loosening state, the telescopic cylinder 9 drives the lower pressing block 16 to press the workpiece to be processed so that the workpiece falls into the upper material rack 12, and the workpiece on the upper material rack 12 is adjusted to ensure that the workpiece to be processed stops stably on the upper material rack 12, and the telescopic cylinder 9 drives the lower pressing block 16 to rise after 2 seconds.

[0034] Secondly, the cross table 4 drives the feeding and discharging mechanism to move, and makes the workpiece to be processed stop at the workpiece feeding position, after the workpiece to be processed stops between the main shaft top pin and the top pin of the clamping mechanism 3, the adjusting seat 20 on the adjusting assembly lifts the workpiece to be processed, the top pin of the clamping mechanism 3 extends to clamp the workpiece between the main shaft mechanism 2 and the top pin of the clamping mechanism 3, and the adjusting seat 20 on the adjusting assembly falls after the clamping signal is in place.

[0035] Then, the cross table 4 drives the rolling mechanism to move to the workpiece to be processed, the rolling wheel 14 is clamped and pressed under the drive of the hydraulic cylinder, the main shaft mechanism 2 starts to rotate after clamping in place, and the cross table 4 drives the rolling mechanism to move to roll the workpiece.

[0036] Finally, after the rolling is completed, the rolling wheel 14 loosens the workpiece, the cross table 4 upper layer drives the workpiece to be processed to the workpiece unloading position, the tailstock of the tailstock mechanism 3 is loosened, the workpiece to be processed falls into the receiving tray 6 and slides to the receiving car 7 along the receiving tray 6. After the tailstock loosening signal of the tailstock mechanism 3 is in place, the cross table 4 upper layer drives the feeding and discharging mechanism to the workpiece feeding position, and the rolling of the next workpiece to be processed is started, and the cycle is repeated. When the workpiece is not discharged from the hopper 8, the tailstock of the tailstock mechanism 3 is tightened, and the workpiece tightening signal is sent, and the rolling cycle stops working.

[0037] The key point of the present application is that at least three rolling wheels 14 are on the same circumference, the pressure of the rolling wheel 14 on the workpiece to be processed is the same, and the feeding and discharging mechanism can not only realize stable feeding of the workpiece to be processed, but also can prevent the workpiece to be processed from being squeezed and collided at the material falling port, and ensure that the workpiece to be processed can be continuously and normally fed from the hopper 8 to the feeding rack 12. In addition, the feeding position, the discharging position and the rolling position of the workpiece to be processed are controlled by the servo motor controlled by the numerical control system, and the repeated positioning accuracy of the X axis and the Z axis meets the requirements of the workpiece to be processed. The tailstock cylinder pressure in the tailstock mechanism 3 is adjustable, which can not only ensure the stability of the workpiece to be processed at the two tailstocks, but also can not cause the bending deformation of the workpiece to be processed.

[0038] The outer circle rolling machine can automatically and continuously roll and process the workpiece to be processed in the hopper after the workpiece to be processed is added, until the workpiece to be processed in the hopper is completely rolled, and the operator does not need to operate in the middle. In the case of workpiece to be processed in the hopper, unmanned automatic rolling can be realized, and the equipment can automatically stop rolling after the workpiece to be processed in the hopper is completely rolled. The outer circle rolling machine can adjust the rolling pressure by adjusting the hydraulic pressure as needed, and the main shaft rotating speed can be adjusted by numerical control program as needed, and the rolling precision is high.
