Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a quenching device for roller processing. Background Art

[0002] Rollers are key components of steel rolling equipment in the metallurgical industry. They are mainly composed of three parts: the roll body, the roll neck and the shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The quenching device used in the roll processing process is mainly to improve the hardness and wear resistance of the roll to meet the high load and harsh working environment during the rolling process. Workers are required to participate in the roll quenching device, and the automation of roll quenching cannot be achieved. In addition, the cooling time of the roll is relatively long.

[0003] In order to solve the above problems, the utility model patent with publication number CN216663181U discloses a roller quenching device, which is convenient for cooperating with the roller transport component to carry out automated roller feeding processing, and is convenient for cooperating with the roller transport component to fix and clamp the roller and send it to the top of the collecting tank for quenching processing. It can adapt to the diameters of rollers of different models and achieve atomization quenching processing close to the roller surface, thereby improving the utilization rate of water resources, reducing water consumption, and being used for classified collection. The mist collection hood uses the hood body to condense water mist, and the condensed water droplets are drained into the water collection tank by the guide groove, and collected through the pump machine circulation, thereby reducing water consumption and greatly saving costs.

[0004] There are still some shortcomings in the use of the above-mentioned quenching device. When the roller is taken out after quenching, the roller is easily subjected to thermal stress and deformation due to the high temperature and rapid cooling, which makes it difficult to take the roller out of the box. It is not convenient to quickly take out the cooled roller, thereby increasing the risk of deformation. When the roller is taken out, a lot of manpower is required to move the roller to the outside of the box, which is easy to cause safety accidents and wastes manpower, increases waiting time in production, and reduces production efficiency.

[0033] Working principle: When discharging the quenched and cooled roller, the bottom of the sealing plate 8 is pushed, so that the sealing plate 8 drives the connecting piece 9 to slide on the inner side of the second slide groove 6, so that the sealing plate 8 drives the top slider 7 to slide on the inner side of the first slide groove 5, so that the sealing plate 8 is tilted and pressed down, and then the sealing plate 8 drives the connecting piece 9 to move to the rear side of the second slide groove 6, pushing the push rod 4, so that the push rod 4 rotates and tilts forward, thereby driving the connecting block 10 to slide on the inner side of the push rod 4 and the inner rear side of the sliding groove 2 to the front side of the sliding groove 2, The connecting blocks 10 on both sides drive the mounting plate 3 forward, and then pull the spring 11, which generates a rebound force, so that the inner tube 13 slides on the inner side of the outer tube 12, thereby driving the roller on the mounting plate 3 to be pushed out of the outside of the quenching box 1. After the roller is removed, the mounting plate 3 is reset under the action of the rebound of the spring 11, thereby driving the sealing plate 8 to close the quenching box 1, so that the roller can be quickly separated from the box after quenching and cooling, reducing the phenomenon of roller deformation caused by manual handling and reducing manual handling of the roller. The human resources wasted during transportation reduce the probability of safety accidents, thereby reducing the waiting time during unloading during production, thereby improving production efficiency. When cooling the roller, the roller is placed on the outside of the two rotating rods 28, and then the motor 14 is started. The motor 14 drives the bidirectional screw rod 15 to rotate, so that the bidirectional screw rod 15 drives the connecting plates 16 on the left and right sides to approach each other, thereby driving the clamping claw 18 and the clamping claw 2 19 to approach each other, clamping the roller, and then injecting the cooling box 20 into the inside. After the cooling liquid is supplied, the boost pump 21 is started, and the spray head 23 sprays the cooling liquid on the roller through the transmission of the connecting pipe 22, and then the motor 17 is started. The motor 17 drives the clamping claw 18 to rotate, thereby driving the roller clamped by the clamping claw 18 and the clamping claw 2 19 to rotate. Through the spraying of the spray head 23, it is convenient to spray the cooling liquid on the roller in an all-round way, thereby improving the uniformity of the water cooling of the roller, and enhancing the stability of the roller when being cooled, thereby improving the cooling efficiency of the roller and shortening the cooling time.
