[0016] A roller shaft forging method, using the forging machine mentioned above, comprises the following steps:

[0017] When the forging of the roller shaft is completed, the forging plate moves upward, and the blanking movable plate drives the arc-shaped clamping plate to move toward the roller shaft, and the lifting column drives the lifting cylinder to move upward so that the top surface of the fixed cylinder, the top surface of the lifting cylinder and the top surface of the lifting column are at the same height, and the roller shaft after forging is moved out of the lifting cylinder. When the arc-shaped clamping plate approaches the roller shaft, the arc-shaped clamping plate moves toward each other and contacts and squeezes the roller shaft. When the arc-shaped clamping plate completes the fixation of the roller shaft, the blanking movable plate drives the arc-shaped clamping plate to move toward the collection box. When the roller shaft moves to the top of the collection box, the arc-shaped clamping plate moves away from each other, releasing the squeeze on the roller shaft, and allowing the roller shaft to fall into the collection box.

[0018] When the roller shaft moves out of the lifting cylinder, the cooling nozzle moves to the top of the lifting cylinder, and the cooling nozzle sprays the bottom surface of the forging plate, the top surface of the fixed cylinder, the top surface of the lifting cylinder and the top surface of the lifting column. When the roller shaft falls into the collecting box, the unloading movable plate moves and resets, and the lifting cleaning brush moves downward and contacts the top surface of the workbench. The movement of the unloading movable plate drives the lifting cleaning brush to move. During the movement, the lifting cleaning brush contacts the top surfaces of the fixed cylinder, the lifting cylinder and the lifting column, and pushes the oxide impurities on the top surfaces of the workbench, the fixed cylinder, the lifting cylinder and the lifting column. The cleaning push plate moves and contacts the top surface of the workbench, pushing the oxide impurities on the top surface of the workbench into the discharge guide bucket, and the discharge guide bucket discharges the oxide impurities. The movement of the cleaning push plate drives the lifting cleaning brush to move upward and reset.

[0019] Compared with the prior art, the present invention provides a forging machine and a roller shaft forging method, which have the following beneficial effects:

[0020] 1. When the roller shaft falls into the collection box, the unloading movable plate moves and resets, and the lifting cleaning brush moves downward to contact the top surface of the workbench. The movement of the unloading movable plate drives the lifting cleaning brush to move. During the movement, the lifting cleaning brush contacts the top surfaces of the fixed cylinder, lifting cylinder and lifting column, and pushes the oxide impurities on the top surfaces of the workbench, fixed cylinder, lifting cylinder and lifting column. The cleaning push plate moves and contacts the top surface of the workbench, pushing the oxide impurities on the top surface of the workbench to move into the discharge guide bucket, which discharges the oxide impurities. The cleaning push plate moves and drives the lifting cleaning brush to move upward and reset. During the unloading process, the oxide impurities on the mold and the workbench are cleaned to prevent the oxide impurities from affecting the forging work and improve the processing accuracy.

[0021] 2. After the forging of the roller shaft is completed, the forging plate moves upward, and the unloading movable plate drives the arc-shaped splint to move toward the direction of the roller shaft, and the lifting column drives the lifting cylinder to move upward, so that the top surface of the fixed cylinder, the top surface of the lifting cylinder and the top surface of the lifting column are at the same height, and the forged roller shaft is moved out of the lifting cylinder. When the arc-shaped splint approaches the roller shaft, the arc-shaped splints move toward each other and contact and squeeze the roller shaft. When the arc-shaped splint completes the fixation of the roller shaft, the unloading movable plate drives the arc-shaped splint to move toward the direction of the collection box. When the roller shaft moves to the top of the collection box, the arc-shaped splints move away from each other, releasing the squeezing of the roller shaft, and allowing the roller shaft to fall into the collection box. The roller shaft after processing is automatically unloaded to avoid manual unloading and avoid scalding of the heated roller shaft to the staff, thereby improving work efficiency and production safety.

[0022] 3. When the roller shaft moves out of the lifting cylinder, the cooling nozzle moves to the top of the lifting cylinder, and the cooling nozzle sprays the bottom surface of the forging plate, the top surface of the fixed cylinder, the top surface of the lifting cylinder and the top surface of the lifting column. During the blanking process, the mold is sprayed and cooled to prevent the mold from overheating, thereby increasing the service life of the mold and improving the forging accuracy.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] A roller shaft forging method, using the forging machine mentioned above, comprises the following steps:

[0062] When the forging of the roller shaft is completed, the forging plate 1101 moves upward, and the unloading movable plate 201 drives the arc clamping plate 202 to move in the direction close to the roller shaft, and the lifting column 1104 drives the lifting cylinder 1103 to move upward, so that the top surface of the fixed cylinder 1102, the top surface of the lifting cylinder 1103 and the top surface of the lifting column 1104 are at the same height, and the roller shaft after the forging is moved out of the lifting cylinder 1103. When the arc clamping plate 202 is close to the roller shaft, the arc clamping plate 202 moves toward each other and contacts and squeezes the roller shaft. When the arc clamping plate 202 completes the fixation of the roller shaft, the unloading movable plate 201 drives the arc clamping plate 202 to move in the direction close to the collection box 203. When the roller shaft moves to the top of the collection box 203, the arc clamping plates 202 move away from each other, releasing the squeezing of the roller shaft, and causing the roller shaft to fall into the collection box 203.

[0063] When the roller shaft moves out of the lifting cylinder 1103, the cooling nozzle 301 moves to the top of the lifting cylinder 1103, and the cooling nozzle 301 sprays the bottom surface of the forging plate 1101, the top surface of the fixed cylinder 1102, the top surface of the lifting cylinder 1103 and the top surface of the lifting column 1104. When the roller shaft falls into the collecting box 203, the unloading movable plate 201 moves to reset, and the lifting cleaning brush 302 moves downward to contact the top surface of the workbench 101. The movement of the unloading movable plate 201 drives the lifting cleaning brush 302 to move, and the lifting cleaning brush 302 moves downward. During the movement, it contacts the top surfaces of the fixed cylinder 1102, the lifting cylinder 1103 and the lifting column 1104, and pushes the oxide impurities on the top surfaces of the workbench 101, the fixed cylinder 1102, the lifting cylinder 1103 and the lifting column 1104 to be cleaned. The cleaning push plate 303 moves and contacts the top surface of the workbench 101, pushing the oxide impurities on the top surface of the workbench 101 to move into the discharge guide bucket 304, and the discharge guide bucket 304 discharges the oxide impurities. The movement of the cleaning push plate 303 drives the lifting cleaning brush 302 to move upward and reset.
