During the quenching process, the roller will increase the temperature of the quenching oil in the quenching pool 3. Therefore, the quenching oil temperature at the top is higher, while the quenching oil temperature at the bottom is lower, which makes the temperature of the roller uneven during quenching. The roller is set to the inner side of the fixed frame 10 and fixedly clamped by the clamping structure. The driver 7 is started. The output end of the driver 7 drives the push rod 8 to move downward, so that the mounting plate 9 and the fixed frame 10 move downward accordingly, so that the fixed frame 10 and the roller enter the quenching pool 3 for quenching. During the movement of the fixed frame 10, the fixed gear 18 is meshed with the fixed rack 6. As the fixed gear 18 moves, the fixed rack 6 causes the fixed gear 18 to rotate. When the fixed gear 18 rotates, it drives the connecting rod 17 to rotate together, so that the clamping structure and the roller rotate together, so that all parts of the roller are subjected to more uniform quenching. A bevel gear 24 is fixedly sleeved on the part of one of the connecting rods 17 located on the inner side of the fixed frame 10, and a bevel gear 16 corresponding to the bevel gear 24 is arranged above the bevel gear 24, and the bevel gear 16 is meshed with the bevel gear 24.

Under the action of the rotating wheel 14 and the transmission belt 15, the connecting shaft 12 and the connecting impeller 13 rotate. When the connecting impeller 13 rotates, the quenching oil below is sucked upward, so that the quenching oil with a lower temperature below flows to the position of the roller, and the quenching oil with a higher temperature flows to both sides, reducing the temperature of the quenching oil in contact with the roller, and improving the quenching effect; The clamping structure includes a connecting cavity 19 opened inside the connecting rod 17, a moving block 20 is slidably connected inside the connecting cavity 19, a clamping rod 21 is fixedly connected to a side wall of the moving block 20 close to the inner side of the fixed frame 10, the clamping rod 21 penetrates the inner side wall of the connecting cavity 19 and extends to the inner side of the fixed frame 10, one end of the clamping rod 21 located inside the fixed frame 10 is fixedly connected to a clamping block 22, one end of the moving block 20 away from the clamping rod 21 is fixedly connected to a connecting spring 23, one end of the connecting spring 23 away from the clamping rod 21 is fixedly connected to the inner side wall of the connecting cavity 19, the clamping block 22 is pushed to both sides, the connecting spring 23 is contracted accordingly, the roller is set between the clamping blocks 22, the clamping block 22 is released, and under the action of the elastic force of the connecting spring 23, the clamping block 22 moves to the position of the roller to fix and clamp the roller; A plurality of vertically arranged buffer springs 4 are fixedly connected to the lower inner wall of the quenching pool 3, a buffer block 5 is arranged at the top of each buffer spring 4, a damper is fixedly connected to each buffer spring 4, the buffer spring 4 is fixedly connected to the corresponding buffer block 5 through the damper, the positions of the plurality of buffer blocks 5 correspond to the positions of the side walls of the fixed frame 10, each buffer block 5 is made of elastic material, a telescopic constraint sleeve is sleeved on the outer side of each buffer spring 4, the two ends of each telescopic constraint sleeve are respectively connected to the bottom wall of the corresponding buffer block 5 and the lower inner wall of the quenching pool 3, when the fixed frame 10 moves downward, it finally contacts with the buffer block 5, with the cooperation of the buffer spring 4 and the damper, the fixed frame 10 is buffered to avoid collision between the fixed frame 10 and the lower inner wall of the quenching pool 3, to keep the equipment from being damaged, and at the same time the constraint sleeve can constrain the position of the buffer spring 4 to avoid deformation outward; A plurality of fixing bolts 25 are fixedly arranged on the mounting plate 9, and the plurality of fixing bolts 25 are all arranged through the mounting plate 9.

Under the action of the rotating wheel 14 and the transmission belt 15, the connecting shaft 12 and the connecting impeller 13 rotate.

Moreover, when the fixed frame 10 moves downward, it finally contacts with the buffer block 5. With the cooperation of the buffer spring 4 and the damper, the fixed frame 10 is buffered to avoid collision between the fixed frame 10 and the lower inner wall of the quenching pool 3, thereby maintaining the equipment and preventing it from being damaged. At the same time, the constraint sleeve can constrain the position of the buffer spring 4 to avoid its deformation to the outside.
