Description
Technical Field
[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a quick-change rotary heat treatment bearing device. Background Technology
[0002] In the heat treatment of metal wires, in order to ensure that the wires are heated evenly, a rotary bearing device is often used to place the wire spool. The spool is driven to rotate by a drive mechanism to ensure the consistency of the heat treatment effect.
[0003] Currently, in traditional rotary heat treatment bearing devices, the rotating mechanism of the bearing coil and the driving mechanism that drives its rotation are usually fixedly connected. When it is necessary to replace the coil of different specifications or to maintain the bearing mechanism, it is often necessary to disassemble the connecting parts between the driving mechanism and the rotating mechanism in a cumbersome manner. The operation steps are complicated and time-consuming, which seriously affects the continuous operation of the production line and reduces production efficiency.
[0004] Meanwhile, although some load-bearing devices have achieved the need for rapid replacement to a certain extent, their structural design has limitations, making it difficult to achieve the rotation of the coil during heat treatment. This results in uneven heating of different parts of the wire, with different heat treatment effects in different parts, affecting the heat treatment quality of the wire and making it difficult to meet the production requirements for high uniformity of heating.
[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A quick-change rotary heat treatment support device includes a base plate, a movable plate, a rotating plate, and a drive motor. The bottom of the base plate is rotatably equipped with several rollers. The top of the base plate is detachably connected to the bottom of the movable plate.

The rotating plate is rotatably mounted on the movable plate via the drive shaft and bearings. The bottom end of the drive shaft has a drive groove. The drive motor is mounted on the bottom of the base plate and drives the drive shaft. The drive shaft is rotatably mounted on the base plate via bearings and has a drive pin at its top. The drive pin is detachably accommodated in the drive groove to enable the drive motor to drive the rotating plate to rotate.
[0009] The quick-change rotary heat treatment bearing device has a first clearance groove at the bottom of the moving plate, the first clearance groove being located in the middle of the moving plate, and the lower end of the drive shaft being accommodated in the first clearance groove.
[0010] The quick-change rotary heat treatment bearing device has a second clearance groove on the top of the base plate, the position of which corresponds to the position of the first clearance groove, and the drive shaft is rotatably accommodated in the second clearance groove.
[0011] The quick-change rotary heat treatment bearing device includes at least two parallel limiting plates on the top surface of the base plate, with the at least two limiting plates located on both sides of the second clearance groove, and a limiting block provided at the same end of the at least two limiting plates; the moving plate is provided with an equal number of limiting slots corresponding to the limiting plates, and the limiting slots are detachably sleeved on the outer walls of the limiting plates and the limiting blocks, with at least two limiting slots located on both sides of the first clearance groove.
[0012] The quick-change rotary heat treatment bearing device includes a first receiving hole on the inner wall of the first clearance groove, a first spring in the first receiving hole, a first stop block connected to one end of the first spring, one end of the first stop block being movably embedded in the first receiving hole, and the other end of the first stop block being movably extended into the drive groove to restrict the rotation of the rotating plate.
[0013] The quick-change rotary heat treatment bearing device includes a second receiving hole provided on the inner wall of the second clearance groove. A second spring is provided in the second receiving hole. One end of the second spring is connected to a second stop. One end of the second stop is movably embedded in the second receiving hole. The other end of the second stop slides against the end face of the drive shaft and the side of the drive pin to restrict the rotation of the drive shaft.
[0014] The quick-change rotary heat treatment bearing device includes a first ball bearing embedded at the end of the first stop away from the first spring, which contacts the outer wall of the drive shaft when the moving plate and the base plate are assembled; a second ball bearing is also embedded at the end of the second stop away from the second spring, which contacts the outer wall of the drive shaft when the moving plate and the base plate are assembled; the first stop and the second stop are offset on the end face of the drive shaft, and the movement direction of the first stop is opposite to that of the second stop, so as to form circumferential limits on the drive shaft and the drive shaft respectively.
[0015] The quick-change rotary heat treatment bearing device includes a positioning groove at each of the four corners of the base plate; a lifting ring at each of the four corners of the moving plate; a lifting plug fixedly connected to the bottom of the lifting ring; a limit slider on one side of the lifting plug; the limit slider is used to limit the lifting plug on the moving plate; and the bottom of the lifting plug can be detachably inserted into the positioning groove to position the moving plate on the base plate.

The drive pin at the top of the drive shaft of the drive motor is detachably housed in a drive groove at the bottom of the drive shaft to drive the rotating plate to rotate. From the perspective of quick disassembly and replacement, because the movable plate and base plate adopt a detachable plug-in structure, and the drive pin and drive groove are detachably engaged, when the wire reel needs to be replaced or maintenance is required, the movable plate can be separated from the base plate, and the drive pin from the drive groove, without complicated operations. This easily completes the replacement or maintenance of the support mechanism, solving the problems of cumbersome and time-consuming disassembly of traditional devices that affect production efficiency, and significantly improving the convenience and efficiency of replacement and maintenance. Regarding uniform heating, the drive motor stably drives the rotating plate through the cooperation of the drive pin and the drive groove, ensuring that the wire reel rotates continuously and smoothly during the heat treatment process. This allows all parts of the wire to be heated evenly, solving the problem of uneven heating of the wire reel caused by the inability of the existing quick-change bearing device to rotate, and ensuring the quality of heat treatment. This structural design cleverly balances both aspects, meeting the dual requirements of efficient changeover and high-quality heat treatment in production. Attached Figure Description

[0038] This utility model provides a quick-change rotary heat treatment bearing device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0039] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0040] Please see Figures 1 to 6 As shown, this utility model provides a quick-change rotary heat treatment support device, which includes a base plate 1, a movable plate 2, a rotating plate 3, and a drive motor 4. Several rollers 5 are rotatably mounted on the bottom of the base plate 1 via bearings. The top of the base plate 1 is detachably connected to the bottom of the movable plate 2. The rotating plate 3 supports the coil to be heat treated, and a drive shaft 31 is fixedly mounted on its bottom. The rotating plate 3 is rotatably mounted on the movable plate 2 via the drive shaft 31 and bearings. A drive groove 32 is provided at the bottom end of the drive shaft 31. The drive motor 4 is mounted on the bottom of the base plate 1 and drives the drive shaft 41. The drive shaft 41 is rotatably mounted on the base plate 1 via bearings and has a drive pin 42 at its top end. The drive pin 42 is detachably housed in the drive groove 32, enabling the drive motor 4 to drive the rotating plate 3 to rotate. In this embodiment, the rollers 5 are positioned away from the drive motor 4, allowing the entire device to move easily. The bearings in the movable plate 2 are thrust bearings, and the bearings in the base plate 1 are deep groove ball bearings. The movable plate 2 is detachably plugged into the base plate 1. The movable plate 2 can be moved relative to the base plate 1 for disassembly and installation, improving the efficiency of replacing the coils before and after heat treatment, thereby increasing heat treatment efficiency. The drive groove 32 is a slot with openings at both ends, recessed upwards from the end face of the drive shaft 31. The drive pin 42 is a slotted pin that matches the drive groove 32, protruding upwards from the end face of the drive shaft 41. The drive pin 42 cooperates with the drive groove 32 to transmit the rotational power of the drive motor 4 to the rotating plate 3, causing the rotating plate 3 to rotate stably. The drive shaft 31 and the turntable are an integral structure. The drive shaft 41 and the motor shaft of the drive motor 4 are fixedly connected by conventional means, ensuring that when the drive motor 4 is working, the drive shaft 41 can rotate around its axis and drive the drive shaft 31 to rotate, thereby causing the rotating plate 3 and the coils carried on the rotating plate 3 to rotate, achieving uniform heating of the coils.
[0041] This quick-change rotary heat treatment bearing device effectively achieves both rapid disassembly and uniform heating. Regarding rapid disassembly, the movable plate 2 and base plate 1 use a detachable plug-in structure, and the drive pin 42 and drive groove 32 are detachably connected. When the wire reel needs to be replaced or maintained, the movable plate 2 can be easily separated from the base plate 1, and the drive pin 42 from the drive groove 32, without complicated operations. This easily completes the replacement or maintenance of the bearing mechanism, solving the problems of cumbersome and time-consuming disassembly that affect production efficiency in traditional devices, significantly improving the convenience and efficiency of replacement and maintenance. As for uniform heating, the drive motor 4 stably drives the rotating plate 3 to rotate through the cooperation of the drive pin 42 and drive groove 32, ensuring that the wire reel rotates continuously and smoothly during heat treatment, allowing all parts of the wire to be heated evenly. This solves the problem of uneven heating of the wire reel caused by the inability to rotate in existing quick-change bearing devices, ensuring the quality of heat treatment. This structural design cleverly balances both aspects, meeting the dual requirements of efficient production changeover and high-quality heat treatment in production.
[0042] The base plate 1 is provided with sliders on both sides along the rolling direction, which are adapted to and connected to heat treatment equipment (such as an annealing furnace). The bottom of the heat treatment equipment is provided with a sliding groove for sliding and accommodating the sliders. The sliders and the sliding grooves cooperate with each other to limit the installation position of the entire support device in the heat treatment equipment, and can prevent the heat in the heat treatment equipment from being lost to the outside through the gap between the support device and the heat treatment equipment, thus affecting the heat treatment effect.
[0043] Please see Figure 6 As shown, a first clearance groove 21 is provided at the bottom of the movable plate 2. The first clearance groove 21 is located in the middle of the movable plate 2, and the lower end of the drive shaft 31 is accommodated in the first clearance groove 21. In this embodiment, the first clearance groove 21 is a "U"-shaped groove formed by recessing upward from the bottom surface of the movable plate 2. The opening of the first clearance groove 21 faces the forward direction of the movable plate 2 during the installation of the movable plate 2 and the base plate 1. The center of the arc end of the first clearance groove 21 is located in the center of the movable plate 2. The drive shaft 31 extends into the first clearance groove 21 through the center via a bearing.
[0044] Please see Figure 5 As shown, a second clearance groove 11 is provided on the top of the base plate 1. The position of the second clearance groove 11 corresponds to the position of the first clearance groove 21. The drive shaft 41 is rotatably accommodated in the second clearance groove 11. In this embodiment, the second clearance groove 11 is a U-shaped groove formed by recessing downward from the top surface of the base plate 1. The opening of the second clearance groove 11 faces the forward direction of the base plate 1 during the installation of the moving plate 2 and the base plate 1. The center of the arc end of the second clearance groove 11 is located in the center of the base plate 1. The drive shaft 41 extends into the second clearance groove 11 through the center via a bearing.
[0045] Please see Figures 2 to 6As shown, the top surface of the base plate 1 is provided with at least two parallel limiting plates 12, which are located on both sides of the second clearance groove 11. At least two limiting plates 12 are provided with limiting blocks 13 at the same end. The moving plate 2 is provided with an equal number of limiting slots 22 corresponding to the limiting plates 12. The limiting slots 22 are detachably sleeved on the outer walls of the limiting plates 12 and the limiting blocks 13. At least two limiting slots 22 are located on both sides of the first clearance groove 21. In this embodiment, there are four limiting inserts 12 and four limiting slots 22. The four limiting inserts 12 are arranged in pairs parallel to each other on both sides of the second clearance groove 11, and the four limiting slots 22 are arranged in pairs parallel to each other on both sides of the first clearance groove 21. The height and width of the limiting block 13 are greater than the height and width of the limiting inserts 12. The width and height of one end of the limiting slot 22 corresponding to the limiting block 13 are adapted to the width and height of the limiting block 13, thereby forming a contact surface in the limiting slot 22. The contact surface abuts against the end face of the limiting block 13, realizing the assembly limitation between the moving plate 2 and the base plate 1. To prevent relative misalignment between the movable plate 2 and the base plate 1, which would affect the installation and use of the entire device; the cross-section of the limiting insert 12 is "T" shaped, and the cross-section of the limiting slot 22 is also "T" shaped to match the cross-section of the limiting insert 12. This design can limit the connection between the movable plate 2 and the base plate 1 in the direction perpendicular to the movable plate 2 and the base plate 1, preventing the movable plate 2 from detaching from the base plate 1; the height and width of the end of the limiting insert 12 away from the limiting stop 13 gradually decrease, forming a guide structure, which facilitates the insertion of the limiting insert 12 into the limiting slot 22 and improves the assembly convenience between the movable plate 2 and the base plate 1.
[0046] When assembling the movable plate 2 and the base plate 1, their positions must first be adjusted so that the first clearance groove 21 and the second clearance groove 11 are opposite each other. This operation can be performed manually or with the aid of a positioning device to ensure that the first clearance groove 21 at the bottom of the movable plate 2 and the second clearance groove 11 at the top of the base plate 1 correspond in spatial position, so as to facilitate the smooth docking of subsequent components. Then, the movable plate 2 is slowly moved closer to the base plate 1 in a vertical direction. During this process, it is necessary to ensure that the drive pin 42 at the top of the drive shaft 41 and the drive groove 32 at the bottom of the transmission shaft 31 remain coaxial. As the movable plate 2 and the base plate 1 gradually approach each other, the drive pin 42 begins to enter the drive groove 32. At this time, it is necessary to keep the movable plate 2 descending smoothly to avoid the drive pin 42 and the drive groove 32 shifting due to shaking. After the drive pin 42 is fully inserted into the drive groove 32, the limiting slot 22 at the bottom of the movable plate 2 fits precisely into the outer wall of the limiting insert 12 and the limiting stop 13 of the base plate 1. At the same time, the lifting inserts 61 at the four corners of the movable plate 2 are also accurately inserted into the corresponding positioning grooves 17 of the base plate 1. In this process, the setting of the first clearance groove 21 and the second clearance groove 11 plays a key role. They provide clearance space for the lower end of the transmission shaft 31 and the upper part of the drive shaft 41, respectively, so that the movable plate 2 and the base plate 1 can avoid each other's protruding parts when they approach each other, ensuring that the end of the transmission shaft 31 and the end of the drive shaft 41 will not interfere, thereby achieving quick assembly. After the above operations are completed, the movable plate 2 is firmly installed on the base plate 1, and the power of the drive motor 4 can be transmitted to the transmission shaft 31 through the cooperation of the drive pin 42 and the drive groove 32, thereby driving the rotating plate 3 to rotate, preparing for the subsequent heat treatment work.
[0047] Please see Figure 4 and Figure 6 As shown, the inner wall of the first clearance groove 21 is provided with a first receiving hole 23, and a first spring 24 is provided in the first receiving hole 23. One end of the first spring 24 is connected to a first stop 25. One end of the first stop 25 is movably embedded in the first receiving hole 23, and the other end of the first stop 25 is movably extended into the drive groove 32 to restrict the rotation of the rotating plate 3. In this embodiment, the position of the first receiving hole 23 is set according to the position of the drive groove 32 when the moving plate 2 and the base plate 1 are not assembled. At this time, the end of the first stop 25 away from the first receiving hole 23 will extend into the drive groove 32, forming a limit on the drive groove 32. This state provides a precise guiding basis for the drive pin 42 to smoothly enter the drive groove 32 during the subsequent assembly process, ensuring that the drive groove 32 is in the preset assembly position.
[0048] During the assembly of the movable plate 2 and the base plate 1, as the drive pin 42 gradually enters the drive groove 32, the end of the drive pin 42 contacts the portion of the first stop 25 that extends into the drive groove 32. Continuing to push the movable plate 2 further into the drive groove 32 causes the drive pin 42 to exert a pushing force on the first stop 25, gradually pushing it out of the drive groove 32. During this process, the first stop 25 is pushed and slides into the first receiving hole 23, penetrating deeper into the first receiving hole 23, while simultaneously compressing the first spring 24, causing it to deform. This process continues until the drive pin 42 is fully inside the drive groove 32. At this point, the first stop 25 is also completely out of the drive groove 32, no longer obstructing the engagement between the drive pin 42 and the drive groove 32, ensuring that the drive motor 4 can smoothly drive the rotating plate 3 to rotate through the engagement of the drive pin 42 and the drive groove 32. When the movable plate 2 and the base plate 1 need to be disassembled, as the drive pin 42 gradually withdraws from the drive groove 32, the previously compressed first spring 24, freed from the constraint of the drive pin 42, begins to recover its elastic deformation and gradually elongates. Under the elastic force of the first spring 24, the first stop block 25 is pushed towards the drive groove 32, eventually re-entering the drive groove 32 and repositioning it. This reset action ensures that the drive groove 32 maintains its accurate position during the next assembly, enabling the drive groove 32 and the drive pin 42 to be assembled quickly and accurately, improving the convenience and efficiency of device assembly and disassembly.
[0049] Please see Figures 4 to 5 As shown, the inner wall of the second clearance groove 11 is provided with a second receiving hole 14. The second receiving hole 14 contains a second spring 15. One end of the second spring 15 is connected to a second stop 16. One end of the second stop 16 is movably embedded in the second receiving hole 14. The two adjacent sides of the other end of the second stop 16 slide against the end face of the drive shaft 41 and the side of the drive pin 42 to restrict the rotation of the drive shaft 41. The position of the second receiving hole 14 is offset from the position of the drive pin 42 when the moving plate 2 and the base plate 1 are not assembled. At this time, the end of the second stop 16 away from the second receiving hole 14 extends out under the elastic force of the second spring 15. Its two adjacent sides slide against the end face of the drive shaft 41 and the side of the drive pin 42, respectively. This resistance restricts the rotation of the drive shaft 41, keeping the drive pin 42 in a fixed orientation in the unassembled state. This facilitates the quick alignment of the drive pin 42 and the drive groove 32 during the assembly process, providing favorable conditions for the precise assembly of the two.
[0050] During the assembly of the movable plate 2 and the base plate 1, as the movable plate 2 gradually approaches the base plate 1, the side wall of the drive shaft 31 contacts the end of the second stop 16 and generates a resisting thrust. Under the action of this thrust, the second stop 16 is pushed into the second receiving hole 14 and gradually releases its restriction on the drive shaft 41 and the drive pin 42. At the same time, the second spring 15 is compressed and deformed. During this process, after the drive shaft 41 is released from its restriction, it can be finely adjusted according to the alignment requirements of the drive pin 42 to ensure that the drive pin 42 can smoothly enter the drive groove 32 and complete the power transmission connection during assembly.
[0051] When the movable plate 2 is disassembled from the base plate 1, the drive shaft 31 moves away with the movable plate 2, and its resisting force on the second stop 16 disappears. The compressed second spring 15 begins to recover its elastic deformation, pushing the second stop 16 to move away from the second receiving hole 14 until the end of the second stop 16 away from the second receiving hole 14 once again comes into contact with the end face of the drive shaft 41 and the side of the drive pin 42, thus restricting the position of the drive shaft 41 and the drive pin 42 again, so that the drive pin 42 maintains a stable posture before the next assembly, so that it can be quickly and accurately aligned with the drive groove 32 during subsequent reassembly.
[0052] Please see Figures 4 to 6 As shown, the first stop 25 has a first ball bearing 26 embedded at its end away from the first spring 24. This first ball bearing 26 contacts the outer wall of the drive shaft 31 when the moving plate 2 and the base plate 1 are assembled. The second stop 16 also has a second ball bearing 18 embedded at its end away from the second spring 15. This second ball bearing 18 contacts the outer wall of the drive shaft 41 when the moving plate 2 and the base plate 1 are assembled. The first stop 25 and the second stop 16 are offset on the end face of the drive shaft 41, and the movement direction of the first stop 25 is opposite to that of the second stop 16, thus forming circumferential limits on the drive shaft 31 and the drive shaft 41 respectively. In this embodiment, the first stop 25 and the second stop 16 are offset on the end face of the drive shaft 41. This offset arrangement ensures that they do not interfere with each other in space and can independently perform their respective limiting functions. Specifically, the first stop 25 moves in the opposite direction to the second stop 16. When the first stop 25 moves towards the drive groove 32 under the action of the first spring 24, the second stop 16 moves towards the drive shaft 41 under the action of the second spring 15; and vice versa. This reverse movement design effectively limits the circumferential movement of the drive shaft 41 and the transmission shaft 31, respectively.
[0053] When the movable plate 2 and the base plate 1 are not assembled, the first stop 25 extends into the drive groove 32 to restrict the circumferential rotation of the drive shaft 31 and prevent it from rotating freely. At the same time, the second stop 16 abuts against the end face of the drive shaft 41 and the side of the drive pin 42, thus constraining the circumferential rotation of the drive shaft 41. During the assembly process, as the drive pin 42 enters the drive groove 32 and pushes the first stop 25 out, and the drive shaft 31 pushes the second stop 16 to release the restriction on the drive shaft 41, the two can smoothly complete the assembly action without interfering with each other, ensuring that the device can operate stably under different conditions. However, due to the elastic force of the first spring 24 and the second spring 15, the outer ends of the first stop 25 and the second stop 16 will respectively abut against the outer surfaces of the drive shaft 41 and the transmission shaft 31. After the drive motor 4 starts working, the drive shaft 41 and the transmission shaft 31 rotate synchronously. The end faces of the first stop 25 and the second stop 16 will alternately abut against the outer surfaces of the drive shaft 41 and the transmission shaft 31, which will affect the normal rotation of the drive shaft 41 and the rotating shaft and cause serious wear. Providing the first ball 26 and the second ball 18 on the end faces of the first stop 25 and the second stop 16 can solve this problem well, ensure normal rotation and reduce wear.
[0054] Please see Figures 1 to 2 As shown, a positioning groove 17 is provided at each of the four corners of the base plate 1; a lifting ring 6 is provided at each of the four corners of the movable plate 2. A lifting plug 61 is fixedly connected to the bottom of the lifting ring 6. A limiting slider 62 is provided on one side of the lifting plug 61. The limiting slider 62 is used to limit the lifting plug 61 on the movable plate 2. The bottom of the lifting plug 61 can be detachably inserted into the positioning groove 17 to position the movable plate 2 on the base plate 1. In this embodiment, the four corners of the movable plate 2 are provided with insertion holes for accommodating the lifting plug 61. A hidden groove is provided on one side wall of the insertion hole corresponding to the limiting slider 62. The limiting slider 62 is accommodated in the hidden groove and can slide up and down along the groove, thereby limiting the lifting plug 61 on the movable plate 2 and preventing the lifting plug 61 from shifting or detaching from the movable plate 2 during movement or operation. When the movable plate 2 needs to be installed onto the base plate 1, the lifting plug 61 is lowered by operating the lifting ring 6. At this time, the bottom of the lifting plug 61 can be accurately inserted into the positioning groove 17 at the corresponding corner of the base plate 1. With the cooperation of the lifting plug 61 and the positioning groove 17, the movable plate 2 is positioned from the four corners, ensuring that the movable plate 2 is accurately installed on the base plate 1 and preventing the movable plate 2 from shaking or shifting when the drive motor 4 drives the rotating plate 3 to rotate. When the movable plate 2 needs to be removed, the lifting plug 61 is raised by pulling the lifting ring 6, and its bottom is pulled out from the positioning groove 17, thus releasing the positioning restriction on the movable plate 2 and facilitating the separation of the movable plate 2 from the base plate 1.
[0055] This structural design, by setting positioning components at the four corners, positions the movable plate 2 from multiple directions. This not only ensures the positional accuracy of the movable plate 2 when assembling with the base plate 1, but also makes the disassembly and assembly process convenient. It effectively improves the stability and reliability of the positioning between the movable plate 2 and the base plate 1, thereby ensuring the stability of the entire device during operation. It also provides convenience for quickly replacing the movable plate 2.
[0056] Please see Figure 6 As shown, multiple third balls 27 are embedded in the bottom of the movable plate 2. The multiple third balls 27 are evenly arranged to avoid the limiting slot 22 and are used to contact the top surface of the base plate 1 to reduce wear between the bottom of the movable plate 2 and the top of the base plate 1.
[0057] Please see Figure 1 As shown, a retaining edge 33 is provided on the top edge of the rotating plate 3. The retaining edge 33 is used to limit the position of the coil carried on the rotating plate 3. In this embodiment, the retaining edge 33 consists of multiple discontinuous protrusions arranged upward from the top edge of the rotating plate 3. The gap between adjacent protrusions can increase the heat-receiving area of the coil carried on the rotating plate 3 and facilitate the removal of the coil from the rotating plate 3.
[0058] In summary, this utility model utilizes a detachable plug-in structure between the movable plate 2 and the base plate 1, and the drive pin 42 and drive groove 32 are detachably coupled. This allows for easy separation without complex operations during coil replacement or maintenance, significantly improving replacement and maintenance efficiency and solving the problem of cumbersome disassembly in traditional devices. Regarding uniform heating, the drive motor 4, through the cooperation of the drive pin 42 and drive groove 32, stably drives the rotating plate 3, ensuring continuous and stable rotation of the coil during heat treatment, resulting in uniform heating of the wire and guaranteeing heat treatment quality. This quick-change rotary heat treatment support device combines rapid disassembly and uniform heating.
