Description

Technical Field

[0001] The present invention relates to the technical field of steel annealing equipment, and particularly to a spheroidizing annealing device for bearing steel with temperature detection. Background Art

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize dimensions, reduce deformation and crack tendency; refine grains, adjust the structure, and eliminate tissue defects. In the process of processing the bar stock for producing bearing steel balls, annealing is an essential process. During the annealing process, the cooling rate of the steel determines the change in the texture of the steel after cooling. In order to better spheroidize the steel subsequently, it is necessary to strictly control the annealing rate and cooling time of the steel.

[0003] Among them, the spheroidization of bearing steel is mostly in the form of long cylinders. During the annealing process, fans are mostly used to accelerate the air cooling speed. However, in this process, the air flow generated by the fans flows in a single direction, which will cause unequal cooling rates of the steel and affect the annealing efficiency of the steel. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a spheroidizing annealing device for bearing steel with temperature detection, which includes a base. A pressure box is fixedly connected to the top of the base. An infrared temperature sensor is fixedly connected to the inner wall of the pressure box. A placement rack is slidably connected to the top of the base. A sealed box door is fixedly connected to the side wall of the placement rack. A driving component is fixedly connected to the inner wall of the placement rack. A separation component is fixedly connected to the side wall of the placement rack;

[0005] A power mechanism, the power mechanism includes a fixing plate fixedly connected to the top of the pressure box. An electric telescopic rod is fixedly connected to the bottom of the fixing plate. A piston plate is fixedly connected to the end of the electric telescopic rod away from the fixing plate. A support frame is fixedly connected to the bottom of the piston plate. A roller is rotatably connected to the bottom of the support frame;

[0006] Control mechanism, the control mechanism includes a sliding groove opened on the inner wall of the base, an air outlet groove one is opened on the inner wall of the base, a sliding plate is slidably connected to the inner wall of the sliding groove, several air outlet grooves two are opened on the top of the sliding plate, an inclined plate is fixedly connected to the top of the sliding plate, a reset assembly is fixedly connected to the inner wall of the air outlet groove one. Before use, place the steel to be annealed on the inner wall of the placement rack and push it into the air pressure box through the sealed box door. Then, turn on the power supply of the electric telescopic rod and the infrared temperature sensor. Detect the temperature change of the steel through the infrared temperature sensor, and the electric telescopic rod extends, forcing the piston plate to slide downward along the inner wall of the air pressure box. During this process, a sealed space is formed between the air pressure box and the piston plate. When the piston plate moves downward, the piston plate will compress the air inside the air pressure box, making the gas inside the air pressure box under high pressure. Under the high-pressure state, the heat loss rate of the steel in the early stage will be slowed down, ensuring that the steel has enough time to perform the annealing process and improving the plasticity of the metal in the later stage. And during the downward movement of the piston plate, the piston plate drives the roller to contact the outer wall of the inclined plate. The downward moving roller will drive the sliding plate to horizontally move along the inner wall of the sliding groove through the inclined plate, making the air outlet groove two coincide with the air outlet groove one to form an exhaust port. At this time, the high-pressure gas inside the air pressure box will be discharged outward through the above exhaust port. Subsequently, the electric telescopic rod drives the piston plate to move upward, enabling external air to enter the air pressure box through the above exhaust port to cool the annealed steel. Through the application of the above components, the heat preservation time of the steel in the early stage can be extended, and the cooling efficiency of the steel can be accelerated.

[0007] Preferably, the reset assembly includes a hydraulic telescopic rod one fixedly connected to the side wall of the inclined plate. A transmission pipe is connected through the side wall of the hydraulic telescopic rod one. A hydraulic telescopic rod two is fixedly connected to the bottom of the fixed plate. After the piston plate moves up to the highest position, the top of the piston plate will contact the hydraulic telescopic rod two and force the hydraulic telescopic rod two to contract under pressure. The contracted hydraulic telescopic rod two will transmit the internal liquid to the hydraulic telescopic rod one through the transmission pipe, forcing the hydraulic telescopic rod one to extend. The extended hydraulic telescopic rod one will drive the sliding plate to horizontally move along the inner wall of the sliding groove through the inclined plate, making the air outlet groove two no longer overlap with the air outlet groove one, providing a sealed space for the subsequent annealing process.

[0008] Preferably, the driving assembly includes several driving rods rotatably connected to the inner wall of the placement rack. A gear one is fixedly connected to the side wall of the driving rod. A transmission belt is sleeved on the outer wall of the driving rod.

[0009] Preferably, the driving assembly further includes a mounting rack fixedly connected to the top of the base. A rotating column is rotatably connected to the inner wall of the mounting rack. A gear two is fixedly connected to the side wall of the rotating column. A turbine spring is fixedly connected to the side wall of the mounting rack. One end of the turbine spring away from the mounting rack is fixedly connected to the outer wall of the rotating column.

[0010] Preferably, the driving component further includes a pulling cable fixedly connected to the outer wall of the rotating column. A number of inclined blocks are fixedly connected to the inner wall of the second gear. A sliding spring block is slidably connected to the inner wall of the rotating column. Utilizing the characteristics of the up-and-down movement of the piston plate, a driving component is arranged inside the device. When the piston plate moves upward, the upward-moving piston plate will drive the bottom rotating column to rotate through the pulling cable. As shown in Figure Five , the rotating second gear will drive the first gear to rotate clockwise. The first gear drives a plurality of transmission belts to rotate synchronously clockwise through the driving rod. The horizontally moving transmission belts will force the cylindrical steel to rotate inside the inner wall of the placement rack. Through the application of the above components, when the external air flows from bottom to top, the cylindrical steel can rotate, avoiding the situation that one end of the bottom of the steel is always in direct contact with the external air, and the top of the steel cannot be effectively cooled, thus affecting the cooling quality of the steel.

[0011] Preferably, the separating component includes a chute opened on the side wall of the placement rack. A number of rolling rods I are slidably connected to the inner wall of the chute. One end of the number of rolling rods I away from the chute is fixedly connected to a sliding track. A spring telescopic rod is fixedly connected to the inner wall of the air pressure box. The other end of the spring telescopic rod is fixedly connected to a sliding square block. The outer wall of the sliding square block is slidably connected to the inner wall of the sliding track.

[0012] Preferably, the separating component further includes an L-shaped sliding rail fixedly connected to the side wall of the sliding track. A right-angled rod is rotatably connected to the side wall of the placement rack. A rolling rod II is fixedly connected to the side wall of the right-angled rod. The outer wall of the rolling rod II is slidably connected to the inner wall of the L-shaped sliding rail. When the piston plate moves downward, as the pulling cable becomes slack, the turbine spring will release the compressed mechanical power, forcing the rotating column to rotate in the reverse direction. The rotating column rotating in the reverse direction will wind the slack pulling cable around the outer wall of the rotating column again. During this process, the rotating column drives the sliding spring block to rotate counterclockwise. As shown in Figure Seven , the arc surface of the sliding spring block contacts the arc surface of the inclined block, forcing the sliding spring block to slide downward along the inner wall of the rotating column. When the turbine spring drives the rotating column to rotate in the reverse direction, the rotating column cannot drive the second gear to rotate through the sliding spring block. Through the application of the above components, each component is reset, providing conditions for subsequent annealing.

[0013] Preferably, the separation component further includes a limiting rod fixedly connected to the side wall of the placement rack. A first rotating square plate is rotatably connected to the side wall of the placement rack. A driving round rod is fixedly connected to the side wall of the first rotating square plate. A second rotating square plate is rotatably connected to the side wall of the limiting rod. A third spring is fixedly connected to the side wall of the driving round rod. The end of the third spring away from the driving round rod is fixedly connected to the inner wall of the second rotating square plate. The side wall of the second gear is meshed with the side wall of the first gear. The end of the transmission pipe away from the first hydraulic telescopic rod is connected to the side wall of the second hydraulic telescopic rod in a penetrating manner. The end of the first hydraulic telescopic rod away from the inclined plate is fixedly connected to the inner wall of the first air outlet groove. The side wall of the piston plate is slidably connected to the inner wall of the air pressure box. Utilizing the characteristic that the above-mentioned conveyor belt drives the cylindrical steel to roll, a separation component is arranged inside the device. After the placement rack is pushed into the device inward, the first gear and the second gear will come into contact and be in a meshed state. When the placement rack slides inward, the sliding square block will contact the inner wall of the sliding track, forcing the spring telescopic rod to extend and accumulate mechanical power, presenting a state as shown in Figure Ten And when the device is running, the spring telescopic rod always provides a pulling force towards the sealing box door for the sliding track. Driven by the pulling force, the first rolling rod moves horizontally along the inner wall of the sliding groove synchronously with the sliding track. During this process, the first rolling rod will push the first rotating square plate to tilt upward with the connection point as the center. The rotating first rotating square plate drives the driving round rod to rotate synchronously and applies a torsional force to the third spring. This torsional force will force the second rotating square plate to have a tendency to tilt outward with the driving round rod as the center. As the conveyor belt drives the cylindrical steel to rotate on the inner wall of the placement rack, the rotating steel will roll on the inner wall of the placement rack. During the rolling process, the second rotating square plate will insert into the gaps between the cylindrical steels. Through the application of the above components, gaps are formed between the steel columns, avoiding the hot air generated by the heat dissipation of the steel from affecting the heat dissipation effect of the surrounding steel.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the characteristic that a period of heat preservation is required before annealing. A piston plate is provided inside the device. Before use, the steel to be annealed is placed on the inner wall of the placement rack and pushed into the air pressure box through the sealed box door. Subsequently, the power supplies of the electric telescopic rod and the infrared temperature sensor are connected. The infrared temperature sensor detects the temperature change of the steel, and the electric telescopic rod extends, forcing the piston plate to slide downward along the inner wall of the air pressure box. During this process, a sealed space is formed between the air pressure box and the piston plate. When the piston plate moves downward, the piston plate compresses the air inside the air pressure box, causing the gas inside the air pressure box to be pressurized to a high-pressure state. Under the high-pressure state, the rate of heat loss in the early stage of the steel is slowed down, ensuring that the steel has sufficient time for the annealing process and improving the plasticity of the metal in the later stage. During the downward movement of the piston plate, the piston plate drives the roller to contact the outer wall of the inclined plate, and the downward-moving roller drives the sliding plate to horizontally move along the inner wall of the sliding groove through the inclined plate, causing the second air outlet groove to coincide with the first air outlet groove to form an exhaust port. At this time, the high-pressure gas inside the air pressure box will be discharged outward through the above exhaust port. Subsequently, the electric telescopic rod drives the piston plate to move upward, enabling external air to enter the air pressure box through the above exhaust port to cool the annealed steel. Through the application of the above components, the heat preservation time of the steel in the early stage can be extended, and the cooling efficiency of the steel can be accelerated.

[0016] (2) The present invention utilizes the characteristic of the above piston plate moving up and down. A driving component is provided inside the device. When the piston plate moves upward, the upward-moving piston plate drives the rotating column at the bottom to rotate by pulling the steel cable, as Figure Five . The rotating gear two will drive the gear one to rotate clockwise. The gear one drives a plurality of transmission belts to rotate synchronously clockwise through the driving rod. The horizontally moving transmission belts will force the cylindrical steel to rotate on the inner wall of the placement rack. Through the application of the above components, when external air flows from bottom to top, the cylindrical steel can rotate, preventing one end at the bottom of the steel from always being in direct contact with the external air, and the top of the steel cannot be effectively cooled, which affects the cooling quality of the steel.

[0017] (3) The present invention utilizes the characteristic that the above transmission belts drive the cylindrical steel to roll. A separation component is provided inside the device. After the placement rack is pushed into the device inward, the gear one and the gear two will come into contact and be in a meshing state. When the placement rack slides inward, the sliding block will contact the inner wall of the sliding track, forcing the spring telescopic rod to extend and accumulate mechanical power, presenting as Figure Tenstate, and when the device is running, the spring telescopic rod always provides a pulling force towards the sealed box door for the sliding track. The sliding track drives the first rolling rod to move horizontally along the inner wall of the chute synchronously under the pulling force. During this process, the first rolling rod will push the first rotating square plate to tilt upwards around the connection point. The rotating first rotating square plate drives the driving round rod to rotate synchronously and applies a torsional force to the third spring. This torsional force will force the second rotating square plate to have a tendency to tilt outwards around the driving round rod. As the transmission belt drives the cylindrical steel to rotate on the inner wall of the placement rack, the rotating steel will roll on the inner wall of the placement rack. During the rolling process, the second rotating square plate will insert into the gaps between the cylindrical steels. Through the application of the above components, gaps exist between the steel columns, avoiding the hot air generated by the heat dissipation of the steel from affecting the heat dissipation effect of the surrounding steel.

[0018] (4) After the piston plate moves up to the highest position in the present invention, the top of the piston plate will contact the second hydraulic telescopic rod and force the second hydraulic telescopic rod to contract under pressure. The contracted second hydraulic telescopic rod will transmit the internal liquid to the first hydraulic telescopic rod through the transmission pipe, forcing the first hydraulic telescopic rod to extend. The extended first hydraulic telescopic rod will drive the sliding plate to move horizontally along the inner wall of the sliding groove through the inclined plate, so that the second air outlet groove no longer overlaps with the first air outlet groove, providing a sealed space for the subsequent annealing process; in addition, when the piston plate moves downwards, as the pulling steel cable becomes slack, the turbine spring will release the mechanical power under pressure, forcing the rotating column to rotate in the reverse direction. The rotating column rotating in the reverse direction will wind the slack pulling steel cable around the outer wall of the rotating column again. During this process, the rotating column drives the sliding spring block to rotate counterclockwise. As Figure Seven shown, the arc surface of the sliding spring block contacts the arc surface of the inclined block, forcing the sliding spring block to slide down along the inner wall of the rotating column. When the turbine spring drives the rotating column to rotate in the reverse direction, the rotating column cannot drive the second gear to rotate through the sliding spring block. Through the application of the above components, each component is reset, providing conditions for the subsequent annealing. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1. Please refer to Figure 1 - Figure 4 , the present invention is a spheroidizing annealing device for bearing steel with temperature detection, including a base 1. A pneumatic box 11 is fixedly connected to the top of the base 1. An infrared temperature sensor 12 is fixedly connected to the inner wall of the pneumatic box 11. A placement rack 14 is slidably connected to the top of the base 1. A sealed box door 13 is fixedly connected to the side wall of the placement rack 14. A driving assembly 5 is fixedly connected to the inner wall of the placement rack 14. A separation assembly 6 is fixedly connected to the side wall of the placement rack 14;

[0035] A power mechanism 2. The power mechanism 2 includes a fixing plate 21 fixedly connected to the top of the pneumatic box 11. An electric telescopic rod 22 is fixedly connected to the bottom of the fixing plate 21. One end of the electric telescopic rod 22 away from the fixing plate 21 is fixedly connected to a piston plate 23. A support frame 24 is fixedly connected to the bottom of the piston plate 23. A roller 25 is rotatably connected to the bottom of the support frame 24;

[0036] Control mechanism 3, the control mechanism 3 includes a sliding groove 31 opened on the inner wall of the base 1, an air outlet groove 32 is opened on the inner wall of the base 1, a sliding plate 33 is slidably connected to the inner wall of the sliding groove 31, and a plurality of air outlet grooves 34 are opened on the top of the sliding plate 33. An inclined plate 35 is fixedly connected to the top of the sliding plate 33, and a reset assembly 4 is fixedly connected to the inner wall of the air outlet groove 32. Before use, the steel to be annealed is placed on the inner wall of the placement rack 14 and pushed into the air pressure box 11 through the sealed box door 13. Subsequently, the power supplies of the electric telescopic rod 22 and the infrared temperature sensor 12 are turned on. The infrared temperature sensor 12 detects the temperature change of the steel, and the electric telescopic rod 22 extends, forcing the piston plate 23 to slide downward along the inner wall of the air pressure box 11. During this process, a sealed space is formed between the air pressure box 11 and the piston plate 23. When the piston plate 23 moves downward, the piston plate 23 will compress the air inside the air pressure box 11, making the gas inside the air pressure box 11 under high pressure. In the high-pressure state, the heat loss rate of the steel in the early stage will be slowed down, ensuring that the steel has enough time to perform the annealing process and improving the plasticity of the metal in the later stage. When the piston plate 23 moves downward, the piston plate 23 drives the roller 25 to contact the outer wall of the inclined plate 35. The downward moving roller 25 will drive the sliding plate 33 to move horizontally along the inner wall of the sliding groove 31 through the inclined plate 35, so that the air outlet groove 34 coincides with the air outlet groove 32 to form an exhaust port. At this time, the high-pressure gas inside the air pressure box 11 will be discharged outward through the above exhaust port. Subsequently, the electric telescopic rod 22 drives the piston plate 23 to move upward, so that external air can enter the air pressure box 11 through the above exhaust port to cool the annealed steel. Through the application of the above components, the heat preservation time of the steel in the early stage can be extended, and the cooling efficiency of the steel can be accelerated.

[0037] Embodiment 2, please refer to Figure 5 - Figure 11 , the present invention is a spheroidizing annealing device for bearing steel with temperature detection. On the basis of Embodiment 1, the reset assembly 4 includes a hydraulic telescopic rod 41 fixedly connected to the side wall of the inclined plate 35. A transmission pipe 42 is connected through the side wall of the hydraulic telescopic rod 41. A hydraulic telescopic rod 43 is fixedly connected to the bottom of the fixed plate 21. After the piston plate 23 moves upward to the highest position, the top of the piston plate 23 will contact the hydraulic telescopic rod 43 and force the hydraulic telescopic rod 43 to contract under pressure. The contracted hydraulic telescopic rod 43 will transmit the internal liquid to the hydraulic telescopic rod 41 through the transmission pipe 42, forcing the hydraulic telescopic rod 41 to extend. The extended hydraulic telescopic rod 41 will drive the sliding plate 33 to move horizontally along the inner wall of the sliding groove 31 through the inclined plate 35, so that the air outlet groove 34 no longer overlaps with the air outlet groove 32, providing a sealed space for the subsequent annealing process.

[0038] The driving component 5 includes a plurality of driving rods 51 rotatably connected to the inner wall of the placement rack 14. A first gear 52 is fixedly connected to the side wall of the driving rod 51. A transmission belt 53 is sleeved on the outer wall of the driving rod 51.

[0039] The driving component 5 further includes a mounting bracket 54 fixedly connected to the top of the base 1. A rotating column 55 is rotatably connected to the inner wall of the mounting bracket 54. A second gear 56 is fixedly connected to the side wall of the rotating column 55. A turbo spring 57 is fixedly connected to the side wall of the mounting bracket 54. One end of the turbo spring 57 away from the mounting bracket 54 is fixedly connected to the outer wall of the rotating column 55.

[0040] The driving component 5 further includes a pulling steel cable 58 fixedly connected to the outer wall of the rotating column 55. A plurality of inclined blocks 59 are fixedly connected to the inner wall of the second gear 56. A sliding spring block 510 is slidably connected to the inner wall of the rotating column 55. Utilizing the characteristic of the piston plate 23 moving up and down, a driving component 5 is arranged inside the device. When the piston plate 23 moves upward, the upward moving piston plate 23 will drive the rotating column 55 at the bottom to rotate through the pulling steel cable 58, as Figure Five shown. The rotating second gear 56 will drive the first gear 52 to rotate clockwise. The first gear 52 drives a plurality of transmission belts 53 to rotate synchronously clockwise through the driving rod 51. The horizontally moving transmission belts 53 will force the cylindrical steel to rotate on the inner wall of the placement rack 14. Through the application of the above components, when the external air flows from bottom to top, the cylindrical steel can rotate, avoiding the situation that one end at the bottom of the steel always directly contacts the external air, while the top of the steel cannot be effectively cooled, affecting the cooling quality of the steel.

[0041] The separation component 6 includes a chute 61 opened on the side wall of the placement rack 14. A plurality of first rolling rods 62 are slidably connected to the inner wall of the chute 61. One end of the plurality of first rolling rods 62 away from the chute 61 is fixedly connected to a sliding track 63. A spring telescopic rod 64 is fixedly connected to the inner wall of the air pressure box 11. The other end of the spring telescopic rod 64 is fixedly connected to a sliding block 65. The outer wall of the sliding block 65 is slidably connected to the inner wall of the sliding track 63.

[0042] The separation component 6 further includes an L-shaped sliding rail 66 fixedly connected to the side wall of the sliding track 63. A right-angle rod 67 is rotatably connected to the side wall of the placement rack 14. A second rolling rod 68 is fixedly connected to the side wall of the right-angle rod 67. The outer wall of the second rolling rod 68 is slidably connected to the inner wall of the L-shaped sliding rail 66. When the piston plate 23 moves downward, as the pulling steel cable 58 becomes slack, the turbo spring 57 will release the compressed mechanical power, forcing the rotating column 55 to rotate in the reverse direction. The rotating column 55 rotating in the reverse direction will wind the slack pulling steel cable 58 around the outer wall of the rotating column 55 again. And in this process, the rotating column 55 drives the sliding spring block 510 to rotate counterclockwise, as Figure SevenAs shown, the arc surface of the sliding spring block 510 contacts the arc surface of the inclined plane block 59, forcing the sliding spring block 510 to slide downward along the inner wall of the rotating column 55. When the turbine spring 57 drives the rotating column 55 to rotate in the opposite direction, the rotating column 55 cannot drive the second gear 56 to rotate through the sliding spring block 510. Through the application of the above components, each component is reset, providing conditions for subsequent annealing.

[0043] The separation component 6 further includes a limiting rod 69 fixedly connected to the side wall of the placement rack 14. A first rotating square plate 610 is rotatably connected to the side wall of the placement rack 14. A driving circular rod 611 is fixedly connected to the side wall of the first rotating square plate 610. A second rotating square plate 612 is rotatably connected to the side wall of the limiting rod 69. A third spring 613 is fixedly connected to the side wall of the driving circular rod 611. One end of the third spring 613 away from the driving circular rod 611 is fixedly connected to the inner wall of the second rotating square plate 612. The side wall of the second gear 56 is meshed with the side wall of the first gear 52. The end of the transmission pipe 42 away from the first hydraulic telescopic rod 41 is connected to the side wall of the second hydraulic telescopic rod 43 in a penetrating manner. The end of the first hydraulic telescopic rod 41 away from the inclined plate 35 is fixedly connected to the inner wall of the first air outlet groove 32. The side wall of the piston plate 23 is slidably connected to the inner wall of the air pressure box 11. Utilizing the characteristic that the above-mentioned transmission belt 53 drives the cylindrical steel to roll, a separation component 6 is arranged inside the equipment. After the placement rack 14 is pushed into the equipment inward, the first gear 52 and the second gear 56 will contact and be in a meshed state. When the placement rack 14 slides inward, the sliding block 65 will contact the inner wall of the sliding track 63, forcing the spring telescopic rod 64 to extend and accumulate mechanical power, presenting a state as Figure Ten shown. During the operation of the equipment, the spring telescopic rod 64 always provides a pulling force towards the sealing box door 13 for the sliding track 63. The sliding track 63 drives the first rolling rod 62 to horizontally move synchronously along the inner wall of the sliding groove 61 under the action of the pulling force. During this process, the first rolling rod 62 will push the first rotating square plate 610 to tilt upward with the connection point as the center. The rotating first rotating square plate 610 drives the driving circular rod 611 to rotate synchronously and applies a torsional force to the third spring 613. This torsional force will force the second rotating square plate 612 to have a tendency to tilt outward with the driving circular rod 611 as the center. As the transmission belt 53 drives the cylindrical steel to rotate on the inner wall of the placement rack 14, the rotating steel will roll on the inner wall of the placement rack 14. During the rolling process, the second rotating square plate 612 will be inserted into the gaps between each cylindrical steel. Through the application of the above components, gaps exist between each steel column, avoiding the hot air generated by the heat dissipation of the steel from affecting the heat dissipation effect of the surrounding steel.

[0044] A specific application of this embodiment is as follows: Before use, place the steel to be annealed on the inner wall of the placement rack 14 and push it into the air pressure box 11 through the sealed box door 13. Subsequently, connect the power supplies of the electric telescopic rod 22 and the infrared temperature sensor 12. Detect the temperature change of the steel through the infrared temperature sensor 12, and the electric telescopic rod 22 extends, forcing the piston plate 23 to slide downward along the inner wall of the air pressure box 11. During this process, a sealed space is formed between the air pressure box 11 and the piston plate 23. When the piston plate 23 moves downward, the piston plate 23 will compress the air inside the air pressure box 11, causing the gas inside the air pressure box 11 to be compressed into a high-pressure state. Under the high-pressure state, the heat loss rate of the steel in the early stage will be slowed down, ensuring that the steel has enough time to perform the annealing process and improving the plasticity of the metal in the later stage. And during the downward movement of the piston plate 23, the piston plate 23 drives the roller 25 to contact the outer wall of the inclined plate 35. The downward-moving roller 25 will drive the sliding plate 33 to horizontally move along the inner wall of the sliding groove 31 through the inclined plate 35, causing the second air outlet groove 34 to coincide with the first air outlet groove 32 to form an exhaust port. At this time, the high-pressure gas inside the air pressure box 11 will be discharged outward through the above exhaust port. Subsequently, the electric telescopic rod 22 drives the piston plate 23 to move upward, enabling external air to enter the air pressure box 11 through the above exhaust port to cool the annealed steel. Through the application of the above components, the heat preservation time of the steel in the early stage can be extended, and the cooling efficiency of the steel can be accelerated.

[0045] Utilizing the characteristics of the piston plate 23 moving up and down, a driving component 5 is provided inside the device. When the piston plate 23 moves upward, the upward-moving piston plate 23 will drive the rotating column 55 at the bottom to rotate by pulling the steel cable 58, as Figure Five shown. The rotating gear two 56 will drive the gear one 52 to rotate clockwise. The gear one 52 drives a plurality of transmission belts 53 to rotate synchronously clockwise through the driving rod 51. The horizontally moving transmission belts 53 will force the cylindrical steel to rotate on the inner wall of the placement rack 14. Through the application of the above components, when the external air circulates from bottom to top, the cylindrical steel can rotate, preventing one end at the bottom of the steel from always being in direct contact with the external air, while the top of the steel cannot be effectively cooled, affecting the cooling quality of the steel.

[0046] Utilizing the characteristics of the transmission belt 53 driving the cylindrical steel to roll, a separation component 6 is provided inside the device. After pushing the placement rack 14 inward into the device, the gear one 52 and the gear two 56 will come into contact and be in a meshed state. When the placement rack 14 slides inward, the sliding square 65 will contact the inner wall of the sliding track 63, forcing the spring telescopic rod 64 to extend and store mechanical power, presenting as Figure Tenstate, and when the device is running, the spring telescopic rod 64 always provides a pulling force towards the sealing box door 13 for the sliding track 63. Driven by the pulling force, the sliding track 63 drives the first rolling rod 62 to move horizontally synchronously along the inner wall of the chute 61. During this process, the first rolling rod 62 will push the first rotating square plate 610 to tilt upwards around the connection point. The rotating first rotating square plate 610 drives the driving round rod 611 to rotate synchronously and applies a torsional force to the third spring 613. This torsional force will force the second rotating square plate 612 to have a tendency to tilt outwards around the driving round rod 611. As the transmission belt 53 drives the cylindrical steel to rotate on the inner wall of the placement rack 14, the rotating steel will roll on the inner wall of the placement rack 14. During the rolling process, the second rotating square plate 612 will insert into the gaps between the cylindrical steels. Through the application of the above components, gaps are formed between the steel columns, avoiding the hot air generated by the heat dissipation of the steel from affecting the heat dissipation effect of the surrounding steel.

[0047] After the piston plate 23 moves up to the highest position, the top of the piston plate 23 will contact the second hydraulic telescopic rod 43 and force the second hydraulic telescopic rod 43 to contract under pressure. The contracting second hydraulic telescopic rod 43 will transmit the internal liquid to the first hydraulic telescopic rod 41 through the transmission pipe 42, forcing the first hydraulic telescopic rod 41 to extend. The extending first hydraulic telescopic rod 41 will drive the sliding plate 33 to move horizontally along the inner wall of the sliding groove 31 through the inclined plate 35, so that the second air outlet groove 34 and the first air outlet groove 32 no longer overlap, providing a closed space for the subsequent annealing process; in addition, when the piston plate 23 moves downward, as the pulling cable 58 becomes slack, the turbine spring 57 will release the mechanical power under pressure, forcing the rotating column 55 to rotate in the opposite direction. The rotating column 55 rotating in the opposite direction will wind the slack pulling cable 58 around the outer wall of the rotating column 55 again. During this process, the rotating column 55 drives the sliding spring block 510 to rotate counterclockwise. As Figure Seven shown, the arc surface of the sliding spring block 510 contacts the arc surface of the inclined block 59, forcing the sliding spring block 510 to slide downward along the inner wall of the rotating column 55. When the turbine spring 57 drives the rotating column 55 to rotate in the opposite direction, the rotating column 55 cannot drive the second gear 56 to rotate through the sliding spring block 510. Through the application of the above components, each component is reset, providing conditions for the subsequent annealing.
