Technical Field
[0001] This utility model relates to the field of rolling mill processing technology, specifically to a rolling mill processing spray quenching device. Background Technology
[0002] Rolls are the main working parts and tools on rolling mills that cause continuous plastic deformation of metal. They are mainly composed of three parts: roll body, roll neck, and shaft head. Rolls can be arranged in two-roll, three-roll, four-roll, or multi-roll configurations in the rolling mill stand. During the processing of rolls, they need to be heated at high temperatures and then cooled by cold water spray to increase their hardness. Therefore, a spray quenching device is used for processing.
[0003] Traditional roll quenching devices have many operational inconveniences. For rolls of different sizes, adjusting the quenching device to adapt to the roll size is often cumbersome and time-consuming. Traditional adjustment methods may involve manually replacing parts or using inaccurate mechanical devices, which not only reduces work efficiency but may also lead to poor quenching effect due to improper adjustment. Therefore, it is necessary to design a roll processing quenching device to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please refer to Figure 1-4 As shown, this utility model provides a roll processing spray quenching device, including a spray quenching box 1, with rotating drums 2 respectively provided on both sides of the inside of the spray quenching box 1, and a cover plate 3 respectively hinged to the top of the two sets of rotating drums 2. The rotating drums 2 and the cover plate 3 are respectively provided with locking grooves 4. A motor 7 is embedded in one end of the inside of the spray quenching box 1, and one set of rotating drums 2 is connected to the output end of the motor 7.
[0023] An adjustment assembly is movably installed inside the spray quenching box 1 at the end away from the motor 7. Another set of rotating drums 2 are connected to one side of the adjustment assembly by bearings. A lifting assembly is installed on the top of the rotating drums 2. Spray nozzles 15 are arranged at one end of the bottom of the lifting assembly. A conveying pump 16 is installed on the outside of the bottom of the spray quenching box 1. A conveying hose 17 is connected between the conveying pump 16 and the lifting assembly.
[0024] Specifically, by adjusting the adjustment component installed on one side inside the spray quenching box 1, one of the sets of rotating drums 2 is moved, thereby adjusting the distance between the two sets of rotating drums 2. When the roll is placed between the two sets of rotating drums 2, the two ends of the roll are engaged in the engagement groove 4 opened inside the rotating drum 2. The cover plate 3 is rotated so that the cover plate 3 clamps and fixes the placed roll. The motor 7 is turned on, and the motor 7 drives the placed roll to rotate inside the spray quenching box 1. At the same time, the conveying pump 16 is turned on. The conveying pump 16 conveys the water inside the spray quenching box 1 to the lifting component through the conveying hose 17, and then sprays it out from the nozzle 15. The lifting component can adjust the height of the nozzle 15.
[0025] The adjustment assembly includes a screw 9, a movable plate 10, and a limiting rod 11. The screw 9 is threadedly connected to the top of the inside of the spray quenching box 1. The movable plate 10 is bearing-connected to one end of the screw 9. Two sets of limiting rods 11 are respectively connected to one end of the movable plate 10 and are slidably connected inside the spray quenching box 1. One set of rotating drums 2 is bearing-connected to one side of the movable plate 10. By rotating the screw 9, the screw 9 pushes the movable plate 10 connected to the bearing to move. The movable plate 10 drives one set of rotating drums 2 to move inside the spray quenching box 1 to adjust the distance between the two sets of rotating drums 2. The limiting rod 11 installed on one side of the movable plate 10 moves inside the spray quenching box 1 to prevent the movable plate 10 from rotating on its own.
[0026] Among them: weight blocks 8 are installed on the bottom outer sides of the two sets of rotating drums 2 respectively. The weight blocks 8 keep one set of rotating drums 2 connected to the bearing at the same level. Support plates 5 are installed on one side of the rotating drum 2 and the cover plate 3 respectively. Threaded pins 6 are connected between the two sets of support plates 5 located at the same position. Through the processing block 8 installed at the bottom of the rotating drum 2, when the set of rotating drums 2 connected to the bearing is in an upright position when it is not running, the cover plate 3 is flipped so that the two sets of support plates 5 overlap. The threaded pins 6 are connected between the two sets of support plates 5, so that the cover plate 3 is fixed on the top of the rotating drum 2.
[0027] The lifting assembly includes a support column 12, a slide groove 13, a moving block 14, and a fixing component. The support column 12 is installed at the top end of the spray quenching box 1. The slide groove 13 is opened inside the support column 12. The moving block 14 is slidably connected inside the slide groove 13. One end of the conveying hose 17 is connected to one side of the moving block 14. Multiple sets of nozzles 15 are installed at the bottom of the moving block 14. The fixing component is installed between the support column 12 and the moving block 14. The moving block 14 slides in the slide groove 13 opened inside the support column 12, and drives the nozzles 15 to move at the top of the spray quenching box 1. The height is adjusted according to the thickness of the roller. After the height is adjusted, the fixing component fixes the moving block 14. Water is delivered into the moving block 14 and then sprayed out from the nozzles 15.
[0028] The fasteners include a groove 18 and a bolt 19. The groove 18 is located on one side of the support column 12. The bolt 19 passes through the groove 18 and is connected to one side of the movable block 14. The bolt 19 moves with the movable block 14 within the groove 18. When the bolt 19 abuts against one side of the support column 12, the adjusted movable block 14 is fixed by the friction between the bolt 19 and the support column 12.
[0029] The spray quenching box 1 has a conical drop trough 20 inside. A filter screen 21 is detachable at the top of the conical drop trough 20. Water after spray quenching flows from the conical drop trough 20 into the bottom of the spray quenching box 1 for storage. When the water passes through the filter screen 21, impurities are filtered out, so that the water can be recycled.
[0030] Working Principle: This utility model provides a roll processing spray quenching device. By rotating the screw 9, the screw 9 pushes the moving plate 10 connected to the bearing to move. The moving plate 10 drives one set of rotating drums 2 to move within the spray quenching box 1, adjusting the distance between the two sets of rotating drums 2. When the roll is placed between the two sets of rotating drums 2, the two ends of the roll are engaged in the engaging grooves 4 opened inside the rotating drum 2. The cover plate 3 is flipped so that the two sets of support plates 5 overlap. The threaded pin 6 connects between the two sets of support plates 5, so that the cover plate 3 is fixed on the top of the rotating drum 2 to perform spray quenching on the placed roll. The rollers are clamped and fixed, and the motor 7 is turned on. The motor 7 drives the placed rollers to rotate inside the spray quenching box 1. At the same time, the conveying pump 16 is turned on. The conveying pump 16 delivers water from inside the spray quenching box 1 to the moving block 14 through the conveying hose 17. The water is then sprayed out by the nozzle 15 to spray quench the rotating rollers. The water after spraying and quenching flows into the bottom of the spray quenching box 1 from the conical drop trough 20 for storage. When the water passes through the filter screen 21, impurities are filtered out, so that the water can be recycled.
