Description

Technical Field

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

[0002] Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The goal is to reduce hardness and improve machinability; eliminate residual stress, stabilize dimensions, and reduce deformation and cracking tendencies; refine grains, adjust the structure, and eliminate structural defects. Annealing is an essential step in the production of bar stock for bearing steel balls. During annealing, the rate at which the steel cools determines the changes in its texture after cooling. To ensure better spheroidization of the steel, the annealing rate and cooling time must be strictly controlled.

[0003] Among them, bearing steel is mostly spheroidized into long cylinders. During the annealing process, fans are often used to accelerate the cooling of air. However, during this process, the airflow generated by the fan flows in a single direction, which will cause the cooling rate of the steel to be uneven, affecting the annealing efficiency of the steel. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a bearing steel spheroidizing annealing device with temperature detection, comprising a base, a pressure box fixedly connected to the top of the base, an infrared temperature sensor fixedly connected to the inner wall of the pressure box, a placement rack slidably connected to the top of the base, a sealed box door fixedly connected to the side wall of the placement rack, a driving assembly fixedly connected to the inner wall of the placement rack, and a separation assembly fixedly connected to the side wall of the placement rack;

[0005] The power mechanism includes a fixed plate fixedly connected to the top of the air pressure box, the bottom of the fixed plate is fixedly connected to an electric telescopic rod, the end of the electric telescopic rod away from the fixed plate is fixedly connected to a piston plate, the bottom of the piston plate is fixedly connected to a support frame, and the bottom of the support frame is rotatably connected to a roller;

[0006] The control mechanism includes a sliding groove provided on the inner wall of the base, an air outlet groove 1 provided on the inner wall of the base, a sliding plate slidably connected to the inner wall of the sliding groove, a plurality of air outlet grooves 2 provided on the top of the sliding plate, an inclined plate fixedly connected to the top of the sliding plate, and a reset assembly fixedly connected to the inner wall of the air outlet groove 1. 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, and then the power of the electric telescopic rod and the infrared temperature sensor is turned on. The temperature change of the steel is detected by the infrared temperature sensor, and the electric telescopic rod is extended, forcing the piston plate to slide downward along the inner wall of the air pressure box. In this process, the air pressure box and the piston plate form a sealed space. When the piston plate moves downward, the piston plate will compress the inside of the air pressure box. The air is compressed inside the air pressure box to form 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 undergo the annealing process and improving the plasticity of the metal in the later stage. In the process of the piston plate moving downward, the piston plate drives the roller to contact the outer wall of the inclined plate, and the downward-moving roller 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 and the first air outlet groove overlap 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, so that external air can enter the interior of the air pressure box through the above exhaust port to cool the annealed steel. Through the application of the above components, the early steel insulation time can be extended, and the cooling efficiency of the steel can be accelerated.

[0007] Preferably, the reset assembly includes a hydraulic telescopic rod 1 fixedly connected to the side wall of the inclined plate, a transmission pipe is connected through the side wall of the hydraulic telescopic rod 1, and a hydraulic telescopic rod 2 is fixedly connected to the bottom of the fixed plate. After the piston plate moves to the highest position, the top of the piston plate will contact the hydraulic telescopic rod 2 and force the hydraulic telescopic rod 2 to be compressed and shrink. The contracted hydraulic telescopic rod 2 transmits the internal liquid to the hydraulic telescopic rod 1 through the transmission pipe, forcing the hydraulic telescopic rod 1 to extend. The extended hydraulic telescopic rod 1 will drive the sliding plate to move horizontally along the inner wall of the sliding groove through the inclined plate, so that the air outlet groove 2 and the air outlet groove 1 no longer overlap, providing a closed space for the subsequent annealing process.

[0008] Preferably, the driving assembly includes a plurality of driving rods rotatably connected to the inner wall of the placement rack, a gear 1 is fixedly connected to the side wall of the driving rod, and a transmission belt is sleeved on the outer wall of the driving rod.

By utilizing the characteristics of the above-mentioned piston plate moving up and down, a driving assembly is provided inside the device. When the piston plate moves upward, the upward-moving piston plate will drive the rotating column at the bottom to rotate by pulling the steel cable, such as Figure 5 The rotating gear 2 will drive gear 1 to rotate clockwise, and gear 1 will drive multiple transmission belts to rotate synchronously clockwise through the driving rod, while the transverse transmission belt will force the cylindrical steel to rotate on the inner wall of the placement rack. Through the application of the above components, when the external air circulates from bottom to top, the cylindrical steel can rotate, avoiding one end of the bottom of the steel always in direct contact with the external air, while the top of the steel cannot be effectively cooled, affecting the cooling quality of the steel.

[0011] Preferably, the separation component includes a slide groove opened on the side wall of the placement rack, a plurality of rolling rods are slidably connected to the inner wall of the slide groove, the ends of the plurality of rolling rods away from the slide groove are fixedly connected to the 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 the sliding block, and the outer wall of the sliding block is slidably connected to the inner wall of the sliding track.

[0012] Preferably, the separation component also includes an L-shaped slide rail fixedly connected to the side wall of the sliding track, a right-angle rod is rotatably connected to the side wall of the placement frame, a rolling rod 2 is fixedly connected to the side wall of the right-angle rod, and the outer wall of the rolling rod 2 is slidably connected to the inner wall of the L-shaped slide rail. When the piston plate moves downward, as the pulling cable becomes loose, the turbine spring will release the compressed mechanical power, forcing the rotating column to rotate in the opposite direction, and the rotating column rotating in the opposite direction will wrap the loose pulling cable around the outer wall of the rotating column again, and in this process, the rotating column drives the sliding spring block to rotate counterclockwise, such as Figure 7 As shown, the arc surface of the sliding spring block contacts the arc surface of the inclined surface 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 opposite direction, the rotating column cannot drive the gear 2 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 also includes a limit rod fixedly connected to the side wall of the placement rack, the side wall of the placement rack is rotatably connected to a rotating square plate 1, the side wall of the rotating square plate 1 is fixedly connected to a driving round rod, the side wall of the limit rod is rotatably connected to a rotating square plate 2, the side wall of the driving round rod is fixedly connected to a spring 3, one end of the spring 3 away from the driving round rod is fixedly connected to the inner wall of the rotating square plate 2, the side wall of the gear 2 is meshed with the side wall of the gear 1, the end of the transmission pipe away from the hydraulic telescopic rod 1 is through-connected to the side wall of the hydraulic telescopic rod 2, the end of the hydraulic telescopic rod 1 away from the inclined plate is fixedly connected to the inner wall of the air outlet groove 1, the side wall of the piston plate is slidably connected to the inner wall of the air pressure box, and the above-mentioned transmission belt drives the cylindrical steel to roll. A separation component is provided inside the equipment, and after the placement rack is pushed inward into the equipment, the gear 1 and the gear 2 will contact and be in a meshing state, and 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 a Figure 10 state, and when the equipment is running, the spring telescopic rod always provides a pulling force for the sliding track in the direction of the sealed box door. The sliding track is driven by the pulling force to drive the rolling rod 1 to move synchronously along the inner wall of the slide groove. In this process, the rolling rod 1 will push the rotating square plate 1 to tilt upward with the connection point as the center. The rotating rotating square plate 1 drives the driving round rod to rotate synchronously and applies a torsional force to the spring 3. The torsional force will force the rotating square plate 2 to produce a tendency to tilt outward with the driving round rod as the center. 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, and the rotating square plate 2 will be inserted into the gap between the cylindrical steels during the rolling process. Through the application of the above components, gaps are created between the steel columns to avoid the heat generated by the heat dissipation of the steel and affect 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 heat preservation for a period of time is required before annealing, and a piston plate is provided inside the equipment. 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. Then, the power of the electric telescopic rod and the infrared temperature sensor is turned on. The infrared temperature sensor detects the temperature change of the steel, and the electric telescopic rod is extended, forcing the piston plate to slide downward along the inner wall of the air pressure box. During this process, the air pressure box and the piston plate form a sealed space. When the piston plate moves downward, the piston plate will compress the air inside the air pressure box, so that the gas inside the air pressure box is pressurized to form a high-pressure state. Under the high-pressure state, the movement of the steel forward will be slowed down. The heat loss rate in the early stage is reduced, so as to ensure that the steel has enough time to undergo the annealing process and improve the plasticity of the metal in the later stage; and in the process of the piston plate moving downward, the piston plate drives the roller to contact the outer wall of the inclined plate, and the downward-moving roller 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 and the first air outlet groove overlap 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, so that external air can enter the interior of the air pressure box through the above exhaust port to cool the annealed steel. Through the application of the above components, the early insulation time of the steel can be extended, and the cooling efficiency of the steel can be accelerated.

[0016] (2) The present invention utilizes the characteristics of the piston plate moving up and down, and sets a driving component inside the device. When the piston plate moves upward, the upward piston plate will drive the rotating column at the bottom to rotate by pulling the steel cable, such as Figure 5 The rotating gear 2 will drive gear 1 to rotate clockwise, and gear 1 will drive multiple transmission belts to rotate synchronously clockwise through the driving rod, while the transverse transmission belt will force the cylindrical steel to rotate on the inner wall of the placement rack. Through the application of the above components, when the external air circulates from bottom to top, the cylindrical steel can rotate, avoiding one end of the bottom of the steel always in direct contact with the external air, while the top of the steel cannot be effectively cooled, affecting the cooling quality of the steel.

[0017] (3) The present invention utilizes the characteristic of the transmission belt to drive the cylindrical steel to roll. A separation component is provided inside the device. When the placement rack is pushed inward into the device, gear 1 and gear 2 will 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 a Figure 10state, and when the equipment is running, the spring telescopic rod always provides a pulling force for the sliding track in the direction of the sealed box door. The sliding track is driven by the pulling force to drive the rolling rod 1 to move synchronously along the inner wall of the slide groove. In this process, the rolling rod 1 will push the rotating square plate 1 to tilt upward with the connection point as the center. The rotating rotating square plate 1 drives the driving round rod to rotate synchronously and applies a torsional force to the spring 3. The torsional force will force the rotating square plate 2 to produce a tendency to tilt outward with the driving round rod as the center. 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, and the rotating square plate 2 will be inserted into the gap between the cylindrical steels during the rolling process. Through the application of the above components, gaps are created between the steel columns to avoid the heat generated by the heat dissipation of the steel and affect the heat dissipation effect of the surrounding steel.

[0018] (4) In the present invention, after the piston plate moves up to the highest position, the top of the piston plate will contact the hydraulic telescopic rod 2 and force the hydraulic telescopic rod 2 to be compressed and contracted. The contracted hydraulic telescopic rod 2 transmits the internal liquid to the hydraulic telescopic rod 1 through the transmission pipe, forcing the hydraulic telescopic rod 1 to extend. The extended hydraulic telescopic rod 1 will drive the sliding plate to move horizontally along the inner wall of the sliding groove through the inclined plate, so that the air outlet groove 2 and the air outlet groove 1 no longer overlap, providing a closed space for the subsequent annealing process; in addition, when the piston plate moves downward, as the pulling steel cable becomes loose, the turbine spring will release the compressed mechanical power, forcing the rotating column to rotate in the opposite direction, and the rotating column rotating in the opposite direction will wrap the loose pulling steel cable around the outer wall of the rotating column again, and in this process, the rotating column drives the sliding spring block to rotate counterclockwise, such as Figure 7 As shown, the arc surface of the sliding spring block contacts the arc surface of the inclined surface 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 opposite direction, the rotating column cannot drive the gear 2 to rotate through the sliding spring block. Through the application of the above components, each component is reset, providing conditions for subsequent annealing. BRIEF DESCRIPTION OF THE DRAWINGS

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, and then the power of the electric telescopic rod 22 and the infrared temperature sensor 12 is turned on. The temperature change of the steel is detected by the infrared temperature sensor 12, and the electric telescopic rod 22 is extended, forcing the piston plate 23 to slide downward along the inner wall of the air pressure box 11. In this process, the air pressure box 11 and the piston plate 23 form a sealed space. When the piston plate 23 moves downward, the piston plate 23 The air inside the air pressure box 11 is compressed, so that the gas inside the air pressure box 11 is pressurized to form 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 undergo the annealing process and improving the plasticity of the metal in the later stage. In the process of the piston plate 23 moving downward, the piston plate 23 drives the roller 25 to contact the outer wall of the inclined plate 35. The downward 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 24 and the air outlet groove 1 32 coincide with each other 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 the outside 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 early steel insulation time can be extended and the cooling efficiency of the steel can be accelerated.

When the piston plate 23 moves downward, as the pulling cable 58 becomes loose, the turbine spring 57 will release the compressed mechanical power, forcing the rotating column 55 to rotate in the opposite direction, and the rotating column 55 rotating in the opposite direction will wrap the loose pulling 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 shown in FIG. Figure 7As 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.

The sliding track 63 is driven by the pulling force to drive the rolling rod 1 62 to move synchronously along the inner wall of the slide groove 61. During this process, the rolling rod 1 62 will push the rotating square plate 1 610 to tilt upward with the connection point as the center.

Through the application of the above components, gaps are created between the steel columns, which prevents the heat 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: before use, the steel to be annealed is placed on the inner wall of the placement rack 14, and is pushed into the interior of the air pressure box 11 through the sealed box door 13, and then the power of the electric telescopic rod 22 and the infrared temperature sensor 12 is turned on. The infrared temperature sensor 12 detects the temperature change of the steel, and the electric telescopic rod 22 is extended, forcing the piston plate 23 to slide downward along the inner wall of the air pressure box 11. During this process, the air pressure box 11 and the piston plate 23 form a sealed space. When the piston plate 23 moves downward, the piston plate 23 will compress the air inside the air pressure box 11, so that the gas inside the air pressure box 11 is pressurized to form a high-pressure state. Under the high-pressure state, the heat loss rate of the steel in the early stage will be slowed down, thereby maintaining the heat preservation. The steel has enough time to undergo the annealing process, thereby improving the plasticity of the metal in the later stage; and in the process of the piston plate 23 moving downward, the piston plate 23 drives the roller 25 to contact the outer wall of the inclined plate 35, and 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 second air outlet groove 34 and the first air outlet groove 32 overlap 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, and then the electric telescopic rod 22 drives the piston plate 23 to move upward, so that external air can enter the interior of the air pressure box 11 through the above exhaust port to cool the annealed steel. Through the application of the above components, the early steel insulation time can be extended, and the cooling efficiency of the steel can be accelerated.

[0045] Taking advantage of the fact that the piston plate 23 moves up and down, a driving assembly 5 is provided inside the device. When the piston plate 23 moves upward, the upward piston plate 23 will drive the bottom rotating column 55 to rotate by pulling the steel cable 58. Figure 5 The rotating gear 2 56 will drive the gear 1 52 to rotate clockwise, and the gear 1 52 will drive multiple transmission belts 53 to rotate synchronously clockwise through the driving rod 51, and the transverse transmission belt 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, avoiding one end of the bottom of the steel always 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] By utilizing the characteristics of the transmission belt 53 driving the cylindrical steel to roll, a separation component 6 is provided inside the device. When the placement rack 14 is pushed inward into the device, the gear 1 52 and the gear 2 56 will contact and be in a meshing 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 Figure 10The state of the device is in the state, and when the device is running, the spring telescopic rod 64 always provides a pulling force for the sliding track 63 in the direction of the sealed box door 13. The sliding track 63 is driven by the pulling force to drive the rolling rod 1 62 to move synchronously along the inner wall of the slide groove 61. During this process, the rolling rod 1 62 will push the rotating square plate 1 610 to tilt upward with the connection point as the center. The rotating rotating square plate 1 610 drives the driving round rod 611 to rotate synchronously and applies a torsional force to the spring three 613. The torsional force will force the rotating square plate 2 612 to produce a tendency to tilt outward with the driving round 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, and the rotating square plate 2 612 will be inserted into the gaps between the cylindrical steels during the rolling process. Through the application of the above components, gaps are created between the steel columns, which prevents the heat 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 to the highest position, the top of the piston plate 23 will contact the hydraulic telescopic rod 2 43 and force the hydraulic telescopic rod 2 43 to be compressed and contracted. The contracted hydraulic telescopic rod 2 43 transmits the internal liquid to the hydraulic telescopic rod 1 41 through the transmission pipe 42, forcing the hydraulic telescopic rod 1 41 to extend. The extended hydraulic telescopic rod 1 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 2 34 and the air outlet groove 1 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 loose, the turbine spring 57 will release the compressed mechanical power, forcing the rotating column 55 to rotate in the opposite direction, and the rotating column 55 rotating in the opposite direction will wrap the loose pulling 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 shown in FIG. Figure 7 As 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 gear 2 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.
