Heat treatment techniques include annealing, surface hardening, precipitation strengthening, tempering, carburizing, normalizing, and quenching.

[0004] Quenching is an important step in the heat treatment process. Generally, it is to obtain a high-hardness martensite structure to improve wear resistance and corrosion resistance. The existing quenching process is to clamp the material manually or by equipment, and then put the normalized material into the quenching liquid for quenching.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0039] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a high-temperature heat treatment device for a fireproof cable tray includes:

[0040] A quenching pool 1, on which symmetrically arranged support plates 19 are fixedly installed;

[0041] Please refer to Figures 1 - 4 , Figure 8 , Figure 9 , clamping plates 8, symmetrically arranged in the quenching pool 1. A clamping mechanism connected to the clamping plates 8 is arranged in the quenching pool 1. The clamping mechanism includes symmetrically arranged guide rods 2 fixedly installed in the quenching pool 1. Guide sleeves 3 are movably installed on the guide rods 2. A movable plate 4 is fixed on the guide sleeves 3. An elastic component connected to the movable plate 4 is arranged in the quenching pool 1. The elastic component is connected to the clamping plates 8 and the inclined plate 9, and the elastic component is also connected to the lifting mechanism and the sliding component. Among them, the elastic component includes symmetrically arranged card slots 5 opened on the movable plate 4. Movable blocks 6 are slidably installed in the card slots 5. Fixed rods 28 are fixed on the movable blocks 6. Springs 7 abutting against the movable blocks 6 are sleeved on the fixed rods 28. The movable blocks 6 are fixedly connected to the clamping plates 8 and the inclined plate 9, and the movable plate 4 is connected to the lifting mechanism and the sliding component.

[0042] Specifically, in order to improve the high-temperature resistance of the cable tray, it is necessary to perform heat treatment on its manufacturing materials. Among them, quenching of the materials is particularly important. The quenching pool 1 is filled with quenching liquid. In the initial state, the guide sleeve 3 is located at the end of the stroke far from the bottom of the quenching pool 1, and the spring 7 is in a compressed state, making the distance between the two movable blocks 6 the smallest and located at the end of the stroke on one side of the card slot 5, and the distance between the two clamping plates 8 is the smallest. When it is necessary to quench the materials, at this time, the materials are placed between the two clamping plates 8, and the lifting mechanism works and drives the movable plate 4 to move towards the bottom of the quenching pool 1. The movable plate 4 will also drive the guide sleeve 3 to move along the length direction of the guide rod 2. The guide sleeve 3 and the guide rod 2 play a guiding role to ensure that the movable plate 4 will not deviate during movement. When the materials between the clamping plates 8 are immersed in the quenching liquid, the materials will be quenched.

[0043] Please refer to Figures 1 - 4 , a lifting mechanism connected to the clamping mechanism is provided on the support plate 19. The lifting mechanism can drive the clamping plate 8 to move in the vertical direction through the clamping mechanism. The lifting mechanism includes a motor 14 fixedly installed on the support plate 19. Pulley 15s are rotatably installed on the support plate 19 in a symmetric manner. A driven component connected to the pulley 15s is provided on the support plate 19. The driven component is connected to the movable plate 4. The rotating shaft of one of the pulley 15s is connected to the output shaft of the motor 14. Among them, the driven component includes a conveyor belt 16 sleeved on the pulley 15s. A support rod 17 is fixed on the conveyor belt 16. A connecting plate 18 fixedly connected to the guide sleeve 3 is fixed on the movable plate 4. A through groove engaged with the support rod 17 is formed in the connecting plate 18.

[0044] It should be noted that when it is necessary to quench the materials, the materials are placed between the clamping plates 8. At this time, the motor 14 works to drive the pulley 15s to rotate, thereby driving the conveyor belt 16 to move. The conveyor belt 16 will drive the support rod 17 to move. Since the support rod 17 is engaged with the through groove, the connecting plate 18 provided with the through groove moves, thereby driving the movable plate 4 and the guide sleeve 3 to move along the length direction of the guide rod 2, so that the clamping plate 8 clamping the materials enters the quenching liquid. When the support rod 17 moves to the end of the stroke towards the bottom of the quenching pool 1, the conveyor belt 16 will drive the support rod 17 to move in a direction away from the quenching pool 1, so that the clamping plate 8 moves towards the initial position, thereby taking out the quenched materials from the quenching pool 1. The motor 14 continues to work, thereby controlling the clamping plate 8 to reciprocate in the vertical direction to continuously quench the materials.

[0045] It is characterized in that it further includes:

[0046] Please refer to Figures 1 - 4 、 Figure 8, Figure 9 , the inclined plate 9 is symmetrically arranged in the quenching pool 1 and connected to the clamping mechanism. The quenching pool 1 is also provided with a sliding assembly connected to the clamping mechanism and the inclined plate 9. The sliding plate assembly can drive the clamping mechanism to move through the inclined plate 9 to drive the clamping plates 8 to move closer to or away from each other. The sliding assembly includes a slide groove 10 opened on the side of the movable plate 4 toward the support plate 19. A sliding block 11 is slidably installed in the slide groove 10. A limiting wheel 12 is fixed on the sliding block 11. The limiting wheel 12 cooperates with the inclined plate 9 and is connected to the guide mechanism.

[0047] Furthermore, the inclined surface of the inclined plate 9 faces the side of the limiting wheel 12. In the initial state, the limiting wheel 12 and the inclined surface of the inclined plate 9 are in a separated state. When the material needs to be quenched, the material is placed between the two clamping plates 8. At this time, the motor 14 works and, under the action of the support rod 17 and the connecting plate 18, drives the movable plate 4 to move along the length direction of the guide rod 2, so that the clamping plate 8 with the material fixed thereon enters the quenching liquid. The movable plate 4 will also drive the sliding block 11 to move to drive the limiting wheel 12 to move. When the limiting wheel 12 moves to a certain position, in order to ensure that the contact surface between the material and the clamping plate 8 can also be quenched, it is necessary to control the clamping plate 8 to separate from the material. Under the action of the guiding mechanism, one of the limiting wheels 12 is driven to move to drive the sliding block 11 to slide in the slide groove 10. When the limiting wheel 12 moves to abut against the inclined surface of the inclined plate 9 When the cam 8 is in the same position as the control panel 9, the inclined plate 9 will move in the direction away from each other, so that the movable block 6 slides in the slot 5 and compresses the spring 7. The movable block 6 will also drive one group of clamping plates 8 to move in the direction away from each other, so that the material in this group of clamping plates 8 is separated from the clamping plates 8, and the other group of clamping plates 8 clamps the material to ensure that the material does not separate from the clamping plates 8. When the quenching of the material in this group of clamping plates 8 is completed, under the action of the guiding mechanism, the limiting wheel 12 is reset, the spring 7 is elastically released, and the movable block 6 is driven to reset, so as to control this group of clamping plates 8 to fix the material again. The movable plate 4 continues to move, and under the action of the guiding mechanism, the other group of clamping plates 8 moves away from each other, so that the material contact surface of the other group of clamping plates 8 is quenched, thereby achieving comprehensive quenching of the material while ensuring that the material is always located in the clamping plate 8.

[0048] See also Figures 1 - 3 , Figures 5 - 7, a guiding mechanism is provided on the support plate 19 and connected to the sliding assembly. The guiding mechanism can act when the clamping mechanism moves, and drives the inclined plate 9 to move in a direction away from each other through the sliding assembly. The guiding mechanism includes a straight groove 20 formed on the support plate 19, a first upper inclined groove 21 formed on the support plate 19 and communicating with the end of the straight groove 20, a first lower inclined groove 22 formed on the support plate 19 and communicating with the first upper inclined groove 21 and the straight groove 20. A clamping assembly connected to the straight groove 20 is provided on the support plate 19, and the clamping assembly is connected to the limiting wheel 12. Among them, the clamping assembly includes a second upper inclined groove 23 formed on the support plate 19 and communicating with the straight groove 20, a second lower inclined groove 24 formed on the support plate 19 and communicating with the second upper inclined groove 23 and the straight groove 20. A limiting rod 13 that cooperates with the straight groove 20, the first upper inclined groove 21 and the first lower inclined groove 22 is fixed on the limiting wheel 12. A limiting structure connected to the limiting rod 13 is provided on the support plate 19. The limiting rod 13 cooperates with the second upper inclined groove 23 and the second lower inclined groove 24. The above-mentioned limiting structure includes guiding rods 25 that are rotatably installed on the support plate 19 and are symmetrically arranged. A torsion spring 26 is sleeved on the rotating shaft of the guiding rod 25. Protrusions 27 that are symmetrically arranged and abut against the guiding rod 25 are fixed on the support plate 19. The guiding rod 25 cooperates with the limiting rod 13.

[0049] Furthermore, the support plate 19 is symmetrically arranged. The first upper inclined groove 21 and the first lower inclined groove 22 are in the same positions on the two support plates 19, while the second upper inclined groove 23 and the second lower inclined groove 24 are in different positions on the two support plates 19 and are staggeredly arranged. In the initial state, the limit rod 13 is located at the intersection position of the first upper inclined groove 21 and the first lower inclined groove 22, making the limit wheel 12 abut against the inclined surface of the inclined plate 9. At this time, the distance between the two clamping plates 8 is the largest, and the material to be quenched can be placed between the clamping plates 8. Meanwhile, the motor 14 operates and controls the movable plate 4 to move away from the quenching pool 1, causing the limit rod 13 to slide in the first upper inclined groove 21 to separate the limit wheel 12 from the inclined plate 9, and the clamping plates 8 fix the material. When the limit rod 13 moves into the straight groove 20, the conveyor belt 16 will drive the support rod 17 to move towards the quenching pool 1 and drive the movable plate 4 to move towards the quenching pool 1, causing the limit rod 13 to slide in the straight groove 20. When the limit rod 13 abuts against the guide rod 25, it drives the guide rod 25 to rotate and drives the torsion spring 26 to move, causing the guide rod 25 to separate from the protrusion 27. When the limit rod 13 separates from the guide rod 25, under the action of the torsion spring 26, the guide rod 25 returns to the position where it abuts against the protrusion 27 again. The limit rod 13 continues to move. When one of the limit rods 13 abuts against the lower guide rod 25, since this guide rod 25 abuts against the protrusion 27, the guide rod 25 will not deflect towards the quenching pool 1, allowing the limit rod 13 to enter the second upper inclined groove 23, causing the limit wheel 12 to move towards the inclined plate 9 and causing the clamping plate 8 on one side of this limit rod 13 to move away from each other. Therefore, the material in contact with this clamping plate 8 will be quenched. The limit rod 13 continues to move. When the limit rod 13 enters the first lower inclined groove 22, the limit wheel 12 will move away from the inclined plate 9, causing the clamping plates 8 to fix the material again until this limit rod 13 enters the straight groove 20 again and the movable plate 4 continues to move. When the limit rod 13 on the other side enters another second upper inclined groove 23, similarly, the material on the other side will be quenched. After quenching is completed, the movable plate 4 moves towards the initial position. When the limit rod 13 moves to abut against the lower guide rod 25 again, this guide rod 25 gives way, keeping the limit rod 13 always in the straight groove 20. When the limit rod 13 moves to abut against the upper guide rod 25 again, this guide rod 25 guides the limit rod 13 into the first lower inclined groove 22, causing the two groups of clamping plates 8 to move away from each other simultaneously, facilitating the removal of the material. Repeating the above steps can achieve the effect that the clamped parts of the material can also be quenched.

[0050] A heat treatment method for a high-temperature heat treatment device of a fireproof cable tray includes the following steps:

[0051] Step 1: When quenching is required, the material to be quenched is placed between the clamping plates 8;

[0052] Step 2: Under the action of the lifting mechanism, the clamping mechanism is driven to move, thereby driving the clamping plate 8 to move toward the quenching pool 1, so that the material enters the quenching pool 1 for quenching;

[0053] Step 3: The clamping mechanism also drives the sliding assembly to move, and under the action of the guiding mechanism, the inclined plates 9 move in a direction away from each other, thereby driving the clamping plates 8 to move in a direction away from each other through the clamping mechanism, so as to ensure that the clamping plates 8 will not affect the quenching of the material during quenching;

[0054] Step 4: After quenching is completed, the lifting mechanism drives the clamping plate 8 to separate from the quenching pool 1 through the clamping mechanism to facilitate the removal of the material after quenching.
