[0029] Working principle: When the device is used, the operation of the second motor 702 can drive the screw rod 703 to rotate, so that the moving block 701 is lifted and lowered under the limit of the limit column 704, and then the cooperation of the other moving block 701 and the guide column 8 makes the two moving blocks 701 drive the upper roller 3 to lift and lower, so as to adjust the distance between the upper roller 3 and the lower roller 4 according to the actual usage. After the adjustment, the steel ingot is placed on the top plate 22, and the operation of the two first telescopic rods 1704 can drive the two clamping plates 1705 to move toward each other, so as to clamp and fix the steel ingot. After the clamping and fixing, the top plate 22 is driven to descend by the operation of the second telescopic rod 21, and the first gear 1702 is driven to rotate by the operation of the fourth motor 1701. The second gear 1703 is driven to rotate, thereby driving the second gear 1703 engaged with it to rotate. When the second gear 1703 rotates, it will drive the ring 16 to rotate as a whole, so that the steel ingot clamped in the ring 16 rotates, achieving the effect of automatic flipping. Finally, the operation of the first motor 6 and the third motor 9 drives the upper roller 3 and the lower roller 4 to rotate, so as to process the steel ingot. During the processing, the water in the water tank 10 flows into the suction pipe 1202 through the operation of the water pump 1201, and then is sprayed out from the nozzle 1205 through the guidance of the shunt pipe 1203 and the outlet pipe 1204, so as to cool the upper roller 3 and the lower roller 4, and the dripping water will be guided by the guide groove 24 and the connecting cavity 25, and flow into the water tank 10 again, so as to achieve the effect of saving water resources.
