The length of the square groove 3 in the front-to-back direction is greater than the length of the bottom plate 506 in the front-to-back direction. The bottom plate 506 is provided with 5110, and the middle part of the bottom plate 506 is fixedly connected with a guide plate 509. The rotating mechanism 507 includes a rotating rod 701. The outer part of the rotating rod 701 is rotatably connected with the inner wall of the mounting frame 503 through a bearing. The outer wall of the rotating rod 701 is fixedly connected with a roller 702, and the outer wall of the roller 702 is sleeved A guide steel wire 703 is provided, the lower side of the guide steel wire 703 is located inside the wire hole 510, a first motor 704 is fixedly connected to the upper surface of the top plate 504, the output end of the first motor 704 is connected to the outer wall of the rotating rod 701 through a transmission belt 705, a transmission pile 706 is fixedly connected to the upper surface of the bottom plate 506, the upper inner wall of the transmission pile 706 is slidably connected to the outer wall of the support rod 502, a groove is provided on the left side of the transmission pile 706, a second motor 707 is fixedly connected to the upper surface of the water tank 1, and a turntable 708 is fixedly connected to the output end of the second motor 707. A raised structure is provided on the upper right side, and the raised structure on the right side of the rotating disk 708 is located on the upper side of the inner groove on the left side of the driving pile 706. The moving mechanism 508 includes a water pump 801, and the outer wall of the water pump 801 is fixedly connected to the rear side of the water tank 1. The output end of the water pump 801 is fixedly connected to a water pipe 802, and the upper end of the water pipe 802 is fixedly connected to a water storage tank 803. The outer wall of the water storage tank 803 is fixedly connected to the outer wall of the mounting frame 503 through a connecting plate 804. The right part of the guide steel wire 703 passes through the water storage tank 803 from top to bottom, and the outer wall of the guide steel wire 703 does not contact the outer wall of the water storage tank 803.

[0033] When quenching the axle connection surface, connect the input end of the water pump 801 to the cooling water source, heat the axle and place it on the upper side of the slide 401, rotate the threaded rod 402 to move the clamping plates 403 on both sides toward the middle to clamp the axle, start the water pump 801 to pump cooling water into the water storage tank 803 through the water pipe 802, and start the first motor 704 to drive the rotating rod 701 to rotate through the transmission belt 705, so that the roller 702 drives the guide steel wire 703 to rotate, and at the same time start the second motor 707 to drive the turntable 708 to rotate. Since the protruding structure on the right side of the turntable 708 is located in the groove on the left side of the transmission pile 706, the rotation of the turntable 708 will drive the transmission pile 706 to move forward and backward, and then the transmission pile 706 drives the bottom plate 506, the mounting frame 503, the guide steel wire 703 and other structures to achieve reciprocating movement in the front and rear directions;

[0034] After the water flow is pumped into the water storage tank 803, it can form a stable water flow along the surface of the downwardly moving guide steel wire 703. After the axle parts come into contact with the water flow, the axle connection surface can be quickly cooled down to complete the quenching. Since the guide steel wire 703 guides the water flow, the water flow flows smoothly downward, which can reduce the cooling effect on the area outside the axle connection surface, and the flowing water flow can ensure the stability of the water temperature.

[0035] And because the guide steel wire 703 moves back and forth at this time, the water flow can evenly cool the bridge connection surface. The moving guide steel wire 703 can scrape off the oxides formed after the bridge connection surface is quickly cooled, preventing the local slow cooling caused by the oxides, and further ensuring the uniformity of quenching.

[0036] When the axle contacts the water flow, the fan 404 is started to deliver airflow to the left. After the airflow passes through the axle surface, since the axle body is a semi-cylindrical structure and the plane of the connection surface faces the left, the airflow quickly converges the steam generated by quenching to the middle of the left side of the axle after passing through the semi-circular surface on the right side, thereby preventing the steam from affecting the high-temperature main structure on the right side of the axle connection surface.

[0037] During the reciprocating movement of the bottom plate 506, the lower side of the guide steel wire 703 synchronously passes through the wire hole 510, and the middle part of the lower side of the guide steel wire 703 is located in the middle of several guide plates 509. The guide plates 509 are inclined. The guide plates 509 located at the upper front and rear sides of the guide steel wire 703 and the guide plates 509 located at the lower front and rear sides of the guide steel wire 703 have their sides away from the guide steel wire 703 facing the upper side and the lower side respectively, so that during the forward and backward movement, the guide plates 509 can guide the water flow to impact the surface of the guide steel wire 703, thereby removing the oxide adhered to the surface of the guide steel wire 703, and the guide plates 509 can mix and cool the water flow to avoid high temperature of the guide steel wire 703, thereby ensuring the temperature of the cooling water.
