Description

Technical Field

[0001] The present invention relates to the technical field of steelmaking and quenching equipment, and in particular to a quenching device for steelmaking and a method of using the same. Background Art

[0002] Quenching equipment for steelmaking, or quenching equipment, is a key part of the heat treatment process, especially for improving the hardness, strength, wear resistance and toughness of steel and metal materials. The quenching process involves heating the steel to a critical temperature, holding it at that temperature, and then rapidly cooling it to transform its internal structure.

[0003] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that when the steel material is fed into the quenching device from the outside, the staff needs to use external lifting equipment and transfer equipment, etc., which is not conducive to conveniently transporting the steel material and improving work efficiency. In addition, the steel material needs to be fixed during transportation and heating. The steel material needs to be fixed when transporting the steel material. When the steel material arrives at the inside of the quenching device, the steel material needs to be removed from the transfer equipment and then fixed inside the quenching device, which makes the fixing work of the steel material more cumbersome and not conducive to improving work efficiency. In addition, in order to improve the stability of the quenching work, the existing quenching device for steelmaking needs to be provided with a fixed structure to enhance the stability of the steel material in the quenching device. However, the steel material is not easy to rotate after being fixed, and the heaters in some quenching devices are provided at the bottom and side. One side of the steel material cannot face the heater directly, resulting in uneven heating of the steel material. Therefore, a quenching device for steelmaking and a method of use thereof are urgently needed to solve the above problems. Summary of the Invention

After the clamping plate 2 moves, it contacts the steel material to clamp and fix the steel material. When the clamping plate 2 moves, it drives the elastic part to stretch.

[0026] The present invention also provides a method for using the quenching device for steelmaking, and the method for using is as follows:

[0027] Step 1: Turn on the external power supply, and the staff controls the servo motor 1 to drive the gear 1 to rotate. When the gear 1 rotates, it moves on the rack plate 1 toward the steel material. When the gear 1 moves, it drives the servo motor 1 and the moving plate to move. When the moving plate moves, it drives multiple universal balls and the telescopic device to move. When the universal balls move, they rotate and contact with the outer surface of the gantry. When the telescopic device moves, it drives the heat shield to move. When the heat shield moves to the top of the steel material, the servo motor 1 stops working.

[0028] In step 2, the staff controls the servo motor 2 to drive the gear 2 to rotate when working, and the gear 2 rotates, drives the rack plate 2 to move vertically in the heat insulation cover, and the rack plate 2 moves, and drives the two trigger plates to move. When one of the trigger plates touches the control block 1, the servo motor 2 drives the rack plate 2 to move upward, and when the other trigger plate touches the control block 2, the servo motor 2 drives the rack plate 2 to move downward. When the rack plate 2 moves, it drives the gear 3 to rotate, and when the gear 3 rotates, it drives the rotating shaft fixed to it to rotate, and when the rotating shaft rotates, it drives the fixed block fixed to it to rotate, and when the fixed block rotates, it drives the limit rod to rotate, and when the limit rod rotates, it drives the two sliding frames to rotate, and when the two sliding frames rotate, they drive multiple adjusting blocks to rotate, and when the multiple adjusting blocks rotate, they drive multiple clamping plates 1 and multiple clamping plates 2 to rotate, and when the multiple clamping plates 1 and multiple clamping plates 2 rotate, they drive the steel material to rotate;

[0029] Step three: when the heat shield moves toward the steel material, it drives two fixed frames, two mounting cylinders, two rotating shafts, fixed blocks, limit blocks, limit rods, sliding frames, two-way threaded rod one and two-way threaded rod two to move. The staff first rotates the two-way threaded rod one to drive the two sliding frames to move in opposite directions on the outer surface of the limit rod. When the two sliding frames move in opposite directions, they drive the two-way threaded rod one and multiple adjusting blocks to move in opposite directions. Then, one of the worms is rotated to drive the protrusion to rotate, and the protrusion drives the limit tube to rotate. The limit tube drives other protrusions and worms to rotate. When the two worms rotate, they drive the two worm wheels to rotate. When the two worm wheels rotate, they drive the two When the two bidirectional threaded rods rotate, the two bidirectional threaded rods rotate, and the multiple adjustment blocks are driven to move on the surface of the sliding frame, and then the output end of the telescopic device is controlled to extend so that the center of the adjustment block is on the same axis as the steel material. The staff controls the rotation of the bidirectional threaded rod 1 again. When the bidirectional threaded rod 1 rotates, it drives the two sliding frames to move relative to each other. When the two sliding frames move relative to each other, it drives the multiple adjustment blocks to move relative to each other. The inner walls of the multiple insulation tubes 1, insulation tubes and insulation tubes 2 are filled with oil. When the multiple adjustment blocks move relative to each other, they drive the multiple clamping plates 1 to contact the steel material. The clamping plate 1 remains stationary after being limited by the steel material, and the adjustment block brings The movable heat insulation cylinder 1 continues to move toward the steel material. When the clamping plate 1 does not move, the piston rod 1 remains stationary. After the heat insulation cylinder 1 contracts the piston rod 1, the oil in the heat insulation cylinder 1 is pushed into the heat insulation tube and then into the inside of the heat insulation cylinder 2. After the oil enters the inside of the heat insulation cylinder 2, it pushes the piston rod 2 to move toward the steel material. When the piston rod 2 moves, it drives the clamping plate 2 to move. After the clamping plate 2 moves, it contacts the steel material and clamps and fixes the steel material. When the clamping plate 2 moves, it drives the elastic part to stretch. After the steel material is clamped and fixed, the staff controls the output end of the telescopic device to contract and drive the heat insulation cover and the steel material to move upward, and controls the servo motor 1 to drive the gear 1 to rotate When the heat shield moves to the top of the quenching equipment body, the servo motor stops working, and the output end of the telescopic device extends to drive the heat shield to move toward the quenching equipment body. When the heat shield moves, it drives the steel material into the quenching equipment body. After the heating of the steel material is completed, the output end of the telescopic device contracts and drives the heat shield and steel material to move upward. The staff controls the servo motor to drive the gear to rotate and drive the movable plate and telescopic device to move toward the water pool. When the heat shield moves to the top of the water pool, the servo motor stops working, and the telescopic device works to drive the steel material into the water pool.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are:

[0031] 1. In the present invention, the staff controls the servo motor to drive the gear to rotate when it is working. When the gear rotates, it drives the movable plate, the telescopic device and the heat insulation cover to move. When the heat insulation cover moves, it drives the clamped steel materials to move, so that the steel materials can enter the interior of the quenching equipment body and the water pool, avoiding relying on external equipment to transport the steel materials, facilitating the transportation of the steel materials into the quenching equipment body and the water pool, and improving the work efficiency of steel material transportation.

[0032] 2. In the present invention, after the oil enters the interior of the second heat-insulating cylinder, it pushes the second piston rod to move toward the steel material. When the second piston rod moves, it drives the second clamping plate to move. After the second clamping plate moves, it contacts the steel material and clamps and fixes the steel material. This is beneficial to improving the stability of the steel material during the transportation process, and is beneficial to being suitable for steel materials of different sizes, thereby increasing the scope of application. The steel material is clamped and fixed all the time during the transportation, heating and cooling processes, which is beneficial to simplifying the work process and improving work efficiency.

[0033] 3. In the present invention, when the fixed block rotates, it drives the limit rod to rotate, and when the limit rod rotates, it drives the two sliding frames to rotate, and when the two sliding frames rotate, they drive multiple adjusting blocks to rotate, and when the multiple adjusting blocks rotate, they drive multiple clamping plates one and multiple clamping plates two to rotate, and when the multiple clamping plates one and multiple clamping plates two rotate, they drive the steel material to rotate. When the steel material rotates inside the quenching equipment body, it is beneficial to make the steel material heated more evenly, thereby achieving a heating effect on the steel material.

[0056] In one embodiment, when the heat shield 5 moves to the top of the steel material 3, the servo motor 1 405 stops working. When the heat shield 5 moves toward the steel material 3, it drives the two fixed frames 506, the two mounting cylinders 511, the two rotating shafts 507, the fixed block 508, the limit block 509, the limit rod 6, the sliding frame 601, the two-way threaded rod 1 602 and the two-way threaded rod 2 603 to move. The staff first rotates the two-way threaded rod 1 602 to drive the two sliding frames 601 to move in opposite directions on the outer surface of the limit rod 6. When the two sliding frames 601 move in opposite directions, they drive the two-way threaded rod 1 602 and the multiple adjustment blocks 7 to move in opposite directions, and then rotate One of the worms 605 drives the protrusion 606 to rotate, the protrusion 606 drives the limiting tube 607 to rotate, the limiting tube 607 drives the other protrusions 606 and the worm 605 to rotate, the two worms 605 drive the two worm wheels 604 to rotate, the two worm wheels 604 drive the two bidirectional threaded rods 603 to rotate, the two bidirectional threaded rods 603 drive the multiple adjustment blocks 7 to move on the surface of the sliding frame 601, and then control the output end of the telescopic device 404 to extend so that the center of the adjustment block 7 and the steel material 3 are on the same axis, and the staff controls the bidirectional threaded rod 602 to rotate again. When the bidirectional threaded rod 602 rotates, it drives the two sliding frames 601 to move relative to each other. When the two sliding frames 601 move relative to each other, they drive multiple adjustment blocks 7 to move relative to each other. The inner walls of multiple insulation cylinders 701, insulation tubes 702 and insulation cylinder 2 8 are filled with oil. When the multiple adjustment blocks 7 move relative to each other, they drive multiple clamping plates 704 to contact the steel material 3. After the clamping plate 704 is limited by the steel material 3, it remains stationary. The adjustment block 7 drives the insulation cylinder 701 to continue to move toward the steel material 3. When the clamping plate 704 does not move, the piston rod 703 remains stationary. After the insulation cylinder 701 contracts the piston rod 703, the insulation cylinder 701 The oil inside is pushed into the insulation tube 702 and then enters the insulation cylinder 2 8. After entering the insulation cylinder 2 8, the oil pushes the piston rod 2 9 to move toward the steel material 3. When the piston rod 2 9 moves, it drives the clamping plate 2 901 to move. After the clamping plate 2 901 moves, it contacts the steel material 3 and clamps and fixes the steel material 3, which is beneficial to improve the stability of the steel material 3 during the transportation process, and is beneficial to be suitable for steel materials 3 of different sizes, thereby increasing the scope of application. The steel material 3 is clamped and fixed during the transportation, heating and cooling processes, which is beneficial to simplify the work process and improve work efficiency. When the clamping plate 2 901 moves, it drives the elastic part 10 to stretch.

[0058] The method of using a quenching device for steelmaking in the embodiment of the present application is as follows:

[0059] Step 1: Turn on the external power supply. When the staff controls the servo motor 1 405, it drives the gear 1 406 to rotate. When the gear 1 406 rotates, it moves on the rack plate 1 402 toward the steel material 3. When the gear 1 406 moves, it drives the servo motor 1 405 and the movable plate 403 to move. When the movable plate 403 moves, it drives multiple universal balls 407 and the telescopic device 404 to move. When the universal balls 407 move, they rotate and contact with the outer surface of the gantry 4. When the telescopic device 404 moves, it drives the heat shield 5 to move. When the heat shield 5 moves to the top of the steel material 3, the servo motor 1 405 stops working.

[0060] Step 2: When the staff controls the servo motor 2 501 to work, it drives the gear 2 503 to rotate. When the gear 2 503 rotates, it drives the rack plate 2 502 to move vertically in the heat shield 5. When the rack plate 2 502 moves, it drives the two trigger plates 510 to move. When one of the trigger plates 510 touches the control block 1 504, the servo motor 2 501 drives the rack plate 2 502 to move upward. When the other trigger plate 510 touches the control block 2 505, the servo motor 2 501 drives the rack plate 2 502 to move downward. When the rack plate 2 502 moves, it drives the gear 3 51 2 rotates, when the gear three 512 rotates, it drives the rotating shaft 507 fixed thereto to rotate, when the rotating shaft 507 rotates, it drives the fixed block 508 fixed thereto to rotate, when the fixed block 508 rotates, it drives the limiting rod 6 to rotate, when the limiting rod 6 rotates, it drives the two sliding racks 601 to rotate, when the two sliding racks 601 rotate, it drives the multiple adjusting blocks 7 to rotate, when the multiple adjusting blocks 7 rotate, they drive the multiple clamping plates 1 704 and the multiple clamping plates 2 901 to rotate, when the multiple clamping plates 1 704 and the multiple clamping plates 2 901 rotate, they drive the steel material 3 to rotate;

[0061] Step three: When the heat shield 5 moves toward the steel material 3, it drives the two fixed frames 506, the two mounting cylinders 511, the two rotating shafts 507, the fixed block 508, the limit block 509, the limit rod 6, the sliding frame 601, the two-way threaded rod 1 602 and the two-way threaded rod 2 603 to move. The staff first rotates the two-way threaded rod 1 602 to drive the two sliding frames 601 to move in opposite directions on the outer surface of the limit rod 6. When the two sliding frames 601 move in opposite directions, they drive the two-way threaded rod 1 602 and the multiple adjustment blocks 7 to move in opposite directions. Then, one of the worm gears 605 is rotated to drive the protrusion 606 to rotate. The protrusion 606 drives the limit tube 607 to rotate. The limit tube 607 drives the other protrusions 606 and the worm gear 605 The two worm gears 605 rotate, and the two worm wheels 604 rotate, and the two worm wheels 604 rotate, and the two bidirectional threaded rods 603 rotate, and the two bidirectional threaded rods 603 rotate, and the multiple adjustment blocks 7 move on the surface of the sliding frame 601, and then the output end of the telescopic device 404 is controlled to extend so that the center of the adjustment block 7 and the steel material 3 are located on the same axis, and the staff again controls the bidirectional threaded rod 602 to rotate, and the bidirectional threaded rod 602 rotates, and the two sliding frames 601 move relative to each other, and the two sliding frames 601 move relative to each other, and the multiple adjustment blocks 7 move relative to each other, and the inner walls of the multiple insulation tubes 701, insulation tubes 702 and insulation tubes 8 are filled with this oil. When the multiple adjustment blocks 7 move relative to each other, they drive the multiple clamping plates 704 to contact the steel material 3. After the clamping plate 704 is limited by the steel material 3, it remains stationary. The adjustment block 7 drives the insulation cylinder 701 to continue to move toward the steel material 3. When the clamping plate 704 does not move, the piston rod 703 remains stationary. After the insulation cylinder 701 contracts the piston rod 703, the oil in the insulation cylinder 701 is pushed into the insulation tube 702 and then into the insulation cylinder 2 8. After the oil enters the insulation cylinder 2 8, it pushes the piston rod 2 9 to move toward the steel material 3. When the piston rod 2 9 moves, it drives the clamping plate 2 901 to move. After the clamping plate 2 901 moves, it contacts the steel material 3 and clamps and fixes the steel material 3. The clamping plate 2 901 When moving, the elastic member 10 is driven to stretch. After the steel material 3 is clamped and fixed, the staff controls the output end of the telescopic device 404 to contract, driving the heat shield 5 and the steel material 3 to move upward, and controls the servo motor 1 405 to drive the gear 1 406 to rotate, driving the movable plate 403 and the telescopic device 404 to move toward the quenching equipment body 1. When the heat shield 5 moves to just above the quenching equipment body 1, the servo motor 1 405 stops working, and the output end of the telescopic device 404 extends to drive the heat shield 5 to move toward the quenching equipment body 1. When the heat shield 5 moves, it drives the steel material 3 into the interior of the quenching equipment body 1. After the heating of the steel material 3 is completed, the output end of the telescopic device 404 contracts, driving the heat shield 5 and the steel material 3 to move upward.The staff controls servo motor 1 405 to drive gear 1 406 to rotate, driving movable plate 403 and telescopic device 404 to move toward pool 2. When heat shield 5 moves to directly above pool 2, servo motor 1 405 stops working, and telescopic device 404 starts working, driving steel material 3 into pool 2.

[0062] Working principle: When the external power supply is turned on, the staff controls the servo motor 405 to drive the gear 406 to rotate. When the gear 406 rotates, it moves on the rack plate 402 toward the steel material 3. When the gear 406 moves, it drives the servo motor 405 and the moving plate 403 to move. When the moving plate 403 moves, it slides with the limit bar 401 and the opposite end of the rack plate 402, so as to enhance the stability of the moving plate 403 when it moves and prevent the moving plate 403 from deflecting. When the moving plate 403 moves, it drives multiple universal balls 407 and the telescopic device 404 to move. When the universal ball 407 moves, it rotates with the outer surface of the gantry 4, and the universal ball 407 is used to reduce the contact between the moving plate 403 and the outer surface of the gantry 4. The friction between the gantry 4 is beneficial to improving the service life. When the telescopic device 404 moves, it drives the heat shield 5 to move. When the heat shield 5 moves to the top of the steel material 3, the servo motor 405 stops working. When the heat shield 5 moves toward the steel material 3, it drives the two fixed frames 506, the two mounting cylinders 511, the two rotating shafts 507, the fixed blocks 508, the limit blocks 509, the limit rods 6, the sliding frames 601, the two-way threaded rod 1 602 and the two-way threaded rod 2 603 to move. The staff first rotates the two-way threaded rod 1 602 to drive the two sliding frames 601 to move in opposite directions on the outer surface of the limit rod 6. When the two sliding frames 601 move in opposite directions, they drive the two-way threaded rod 1 602 and multiple adjustment blocks 7 to move in opposite directions, and then rotate one of them. The worm 605 drives the protrusion 606 to rotate, the protrusion 606 drives the limiting tube 607 to rotate, the limiting tube 607 drives other protrusions 606 and the worm 605 to rotate, and the two worms 605 drive the two worm wheels 604 to rotate when the two worm wheels 604 rotate, and the two bidirectional threaded rods 603 drive the two bidirectional threaded rods 603 to rotate when the two bidirectional threaded rods 603 rotate, and the multiple adjustment blocks 7 are moved on the surface of the sliding frame 601 when the two bidirectional threaded rods 603 rotate. Then the output end of the telescopic device 404 is controlled to extend so that the center of the adjustment block 7 and the steel material 3 are located on the same axis. The staff again controls the bidirectional threaded rod 602 to rotate. When the bidirectional threaded rod 602 rotates, it drives the two sliding frames 601 to move relative to each other. The two sliding frames 601 move relative to each other. When moving, it drives multiple adjustment blocks 7 to move relative to each other. The inner walls of multiple insulation cylinders 1 701, insulation tubes 702 and insulation cylinder 2 8 are filled with this oil. When multiple adjustment blocks 7 move relative to each other, they drive multiple clamping plates 1 704 to contact with steel material 3. Clamping plate 1 704 remains stationary after being limited by steel material 3. Adjustment block 7 drives insulation cylinder 1 701 to continue to move toward steel material 3. When clamping plate 1 704 does not move, piston rod 1 703 remains stationary. After insulation cylinder 1 701 contracts piston rod 1 703, the oil in insulation cylinder 1 701 is pushed into insulation tube 702 and then into insulation cylinder 2 8. After the oil enters the insulation cylinder 2 8, it pushes piston rod 2 9 to move toward steel material 3. When piston rod 2 9 moves, it drives clamping plate 2 901 to move.After the clamping plate 2 901 moves, it contacts the steel material 3 and clamps and fixes the steel material 3, which is beneficial to improving the stability of the steel material 3 during the transportation process, and is beneficial to being applicable to steel materials 3 of different sizes, thereby increasing the scope of application. The steel material 3 is clamped and fixed during the transportation, heating and cooling processes, which is beneficial to simplifying the working process and improving working efficiency. When the clamping plate 2 901 moves, it drives the elastic member 10 to stretch. After the steel material 3 is clamped and fixed, the staff controls the output end of the telescopic device 404 to contract and drive the heat shield 5 and the steel material 3 to move upward. When the servo motor 1 405 drives the gear 1 406 to rotate, it drives the movable plate 403 and the telescopic device 404 to move toward the quenching equipment body 1, and the heat shield 5 moves to When the servo motor 405 is directly above the quenching equipment body 1, the output end of the telescopic device 404 extends to drive the heat shield 5 to move toward the quenching equipment body 1. When the heat shield 5 moves, it drives the steel material 3 to enter the quenching equipment body 1. After the heating of the steel material 3 is completed, the output end of the telescopic device 404 contracts to drive the heat shield 5 and the steel material 3 to move upward. The staff controls the servo motor 405 to drive the gear 406 to rotate and drive the movable plate 403 and the telescopic device 404 to move toward the water pool 2. When the heat shield 5 moves to directly above the water pool 2, the servo motor 405 stops working, and the telescopic device 404 works to drive the steel material 3 into the water pool 2, avoiding relying on external equipment to transport the steel material 3, which is beneficial to It is convenient to transport the steel material 3 into the quenching equipment body 1 and the water pool 2. During use, after the steel material 3 enters the quenching equipment body 1, the staff controls the servo motor 2 501 to work and drives the gear 2 503 to rotate. When the gear 2 503 rotates, it drives the rack plate 2 502 to move vertically in the heat insulation cover 5. When the rack plate 2 502 moves, it drives the two trigger plates 510 to move. When one of the trigger plates 510 touches the control block 1 504, the servo motor 2 501 drives the rack plate 2 502 to move upward. When the other trigger plate 510 touches the control block 2 505, the servo motor 2 501 drives the rack plate 2 502 to move downward. When the rack plate 2 502 moves, it drives the gear 3 512 to move. When the gear 3 512 rotates, it drives the rotating shaft 507 fixed thereto to rotate. When the rotating shaft 507 rotates, it drives the fixed block 508 fixed thereto to rotate. When the fixed block 508 rotates, it drives the limiting rod 6 to rotate. When the limiting rod 6 rotates, it drives the two sliding racks 601 to rotate. When the two sliding racks 601 rotate, it drives the multiple adjustment blocks 7 to rotate. When the multiple adjustment blocks 7 rotate, they drive the multiple clamping plates 1 704 and the multiple clamping plates 2 901 to rotate. When the multiple clamping plates 1 704 and the multiple clamping plates 2 901 rotate, they drive the steel material 3 to rotate. When the steel material 3 rotates inside the quenching equipment body 1, it is beneficial to make the steel material 3 more evenly heated, and the heating effect of the steel material 3 is improved.

When the rack plate 2 (502) moves, it drives the gear 3 (510) to move downward. 2) rotates, when the gear 3 (512) rotates, the rotating shaft (507) fixed thereto rotates, when the rotating shaft (507) rotates, the fixed block (508) fixed thereto rotates, when the fixed block (508) rotates, the limiting rod (6) rotates, when the limiting rod (6) rotates, the two sliding racks (601) rotate, when the two sliding racks (601) rotate, the multiple adjusting blocks (7) rotate, when the multiple adjusting blocks (7) rotate, the multiple clamping plates (704) and the multiple clamping plates (901) rotate, when the multiple clamping plates (704) and the multiple clamping plates (901) rotate, the steel material (3) rotates; Step 3: When the heat shield 5 moves toward the steel material (3), it drives the two fixed frames (506), the two mounting cylinders (511), the two rotating shafts (507), the fixed block (508), the limit block (509), the limit rod (6), the sliding frame (601), the two-way threaded rod 1 (602) and the two-way threaded rod 2 (603) to move. The staff first rotates the two-way threaded rod 1 (602) to drive the two sliding frames (601) to move in opposite directions on the outer surface of the limit rod (6). When the two sliding frames (601) move in opposite directions, they drive the two-way threaded rod 1 (602) and the multiple adjustment blocks (7) to move in opposite directions. Then, one of the worm gears (605) is rotated to drive the protrusion (606) to rotate. The protrusion (606) drives the two sliding frames (601) to move in opposite directions. The movable limit tube (607) rotates, and the limit tube (607) drives the other protrusions (606) and the worm (605) to rotate. When the two worms (605) rotate, they drive the two worm wheels (604) to rotate. When the two worm wheels (604) rotate, they drive the two bidirectional threaded rods (603) to rotate. When the two bidirectional threaded rods (603) rotate, they drive multiple adjustment blocks (7) to move on the surface of the sliding frame (601). Then, the output end of the telescopic device (404) is controlled to extend so that the center of the adjustment block (7) and the steel material (3) are located on the same axis. The staff controls the bidirectional threaded rod (602) to rotate again. When the bidirectional threaded rod (602) rotates, it drives the two sliding frames (601) to move relative to each other. When the two sliding frames (601) move relative to each other, the multiple adjustment blocks (7) are driven to move relative to each other. The inner walls of the multiple insulation tubes (701), insulation pipes (702) and insulation tubes (8) are filled with the oil. When the multiple adjustment blocks (7) move relative to each other, the multiple clamping plates (704) are driven to contact the steel material (3). The clamping plate (704) is limited by the steel material (3) and remains stationary. The adjustment block (7) drives the insulation tube (701) to continue to move toward the steel material (3). When the clamping plate (704) does not move, the piston rod (703) remains stationary. After the insulation tube (701) contracts the piston rod (703), the oil in the insulation tube (701) is pushed into the insulation pipe (702) and then enters the insulation tube (702). Inside the second cylinder (8), the oil enters the second heat-insulating cylinder (8) and pushes the second piston rod (9) to move toward the steel material (3). When the second piston rod (9) moves, it drives the second clamping plate (901) to move. After the second clamping plate (901) moves, it contacts the steel material (3) and clamps and fixes the steel material (3). When the second clamping plate (901) moves, it drives the elastic member (10) to stretch. After the steel material (3) is clamped and fixed, the staff controls the output end of the telescopic device (404) to contract and drive the heat-insulating cover (5) and the steel material (3) to move upward. When the servo motor (405) is controlled to drive the gear (406) to rotate, it drives the moving plate (403) and the telescopic device (404) to move toward the quenching device body (1).When the heat shield (5) moves to the top of the quenching equipment body (1), the servo motor 1 (405) stops working, the output end of the telescopic device (404) extends to drive the heat shield (5) to move toward the quenching equipment body (1), and when the heat shield (5) moves, the steel material (3) is driven to enter the quenching equipment body (1). After the heating of the steel material (3) is completed, the output end of the telescopic device (404) contracts to drive the heat shield (5) and the steel material (3) to move upward. The staff controls the servo motor 1 (405) to drive the gear 1 (406) to rotate and drive the moving plate (403) and the telescopic device (404) to move toward the water pool (2). When the heat shield (5) moves to the top of the water pool (2), the servo motor 1 (405) stops working, and the telescopic device (404) works to drive the steel material (3) to enter the water pool (2).
