Description

Technical Field

[0001] This application relates to the field of quenching equipment technology, and in particular to a high-performance spring coil quenching transfer device. Background Technology

[0002] Springs are a common type of mechanical elastic element. During the processing of springs, the high-temperature springs after forming need to be quenched. This involves placing the high-temperature springs in a low-temperature quenching medium and rapidly cooling them to cause a targeted transformation in the microstructure of the spring material, thereby improving the spring's hardness, strength, and elastic limit.

[0003] Chinese Patent Publication No. CN120366561A discloses a spring quenching device with a circulating cooling mechanism, including a quenching tank, a conveyor belt, and a collection box. A support frame is installed at one end of the quenching tank, and a fan is installed on the outside of the support frame. A circulating water pump is installed on the outer wall of the quenching tank below the support frame. The input end of the circulating water pump extends into the interior of the quenching tank through a first water pipe, and the output end of the circulating water pump is connected to an S-shaped pipe inside the support frame through a second water pipe. The output end of the S-shaped pipe is connected to a third water pipe on the outside of the quenching tank. Spray nozzles are also evenly arranged on both sides of the quenching tank. This quenching device, by setting up a support platform and a conveyor belt inside the quenching tank and using a servo motor to drive the conveyor belt, achieves continuous automatic conveying of springs. The uniform movement of the conveyor belt ensures that the springs are heated evenly during the quenching process, significantly improving quenching efficiency and quality.

[0004] However, during the high-temperature processing before quenching, the spring surface undergoes an oxidation reaction with oxygen in the air, resulting in a dense oxide scale adhering to the spring surface. The existing quenching devices cannot remove the oxide scale before quenching. The presence of this oxide scale hinders the heat transfer efficiency during quenching, leading to inconsistent cooling rates between the spring surface and the interior, which in turn reduces the quenching quality of the spring and has significant shortcomings. Summary of the Invention

[0005] To improve the quenching quality of springs, this application provides a high-performance spring coil quenching transfer device.

[0006] The high-performance spring coil quenching transfer device provided in this application adopts the following technical solution: A high-performance spring coil quenching transfer device includes a quenching box, an inlet at one end for the spring to enter, and an outlet at the other end. The quenching box contains a quenching pool filled with quenching oil. A tracked conveyor is installed within the quenching pool, with its end extending to the outlet. A peeling frame is provided, which is inclined from top to bottom along the direction close to the quenching box. The peeling frame has a feed port for a spring to enter. A support plate is slidably connected inside the peeling frame in the horizontal direction. The spring moves to the surface of the support plate through the feed port. A frosted layer is provided on the surface of the peeling frame in the inclined direction. The frosted layer abuts against the outer surface of the spring. An inner cleaning assembly is provided on the peeling frame. The inner cleaning assembly includes a connecting shaft slidably connected in the inclined direction of the peeling frame. A frosted ring plate is provided on the connecting shaft. In the initial state, the spring is sleeved on the outer surface of the connecting shaft, and the frosted ring plate abuts against the inner surface of the spring.

[0007] Optionally, the internal cleaning assembly further includes an internal threaded sleeve. The side wall of the peeling frame is provided with a sliding groove that slides and engages with the internal threaded sleeve along an inclined direction. The outer surface of the connecting shaft is provided with a spiral groove that threads and engages with the internal threaded sleeve. A limit block is provided on the outer surface of the internal threaded sleeve. A limit groove is provided on the inner side wall of the sliding groove that slides and engages with the limit block. The peeling frame is provided with a drive assembly that drives the internal threaded sleeve to move and the connecting shaft to rotate. When the internal threaded sleeve moves to the bottom of the sliding groove, the abrasive ring plate disengages from the spring.

[0008] Optionally, the drive assembly includes a take-up shaft rotatably connected to the peeling frame, a first connecting rope wound on the take-up shaft, the first connecting rope being disposed on the inner threaded sleeve, an outer toothed ring rotatably connected to the end face of the inner threaded sleeve, a limiting block being disposed on the inner sidewall of the outer toothed ring, a limiting groove being formed along the axial direction of the connecting shaft to slide with the limiting block, the limiting groove communicating with the spiral groove, and a rack plate being fixedly disposed along the inclined direction to mesh with the outer toothed ring.

[0009] Optionally, the stripping frame is provided with a cleaning assembly, which includes a cleaning plate disposed on the spring's forward face. One end of the cleaning plate is detachably connected to the end face of the inner threaded sleeve, and the other end is provided with a moving block. The inner sidewall of the stripping frame is provided with a moving groove that slides with the moving block. The end of the winding shaft extends into the moving groove and winds up a second connecting rope, which is disposed on the moving block. The end of the stripping frame near the inlet is provided with a waste chip trough, and the bottom of the stripping frame is provided with a collection box that communicates with the waste chip trough.

[0010] Optionally, the peeling frame is equipped with an air pump, the air outlet of the air pump is equipped with an air pipe, the cleaning plate has an air cavity communicating with the air pipe, the end face of the cleaning plate away from the connecting shaft is equipped with a plurality of air nozzles communicating with the air cavity, the air outlet direction of the air nozzles is towards the surface of the abrasive layer, and the bottom surface of the cleaning plate is equipped with a brush layer, the brush layer abutting against the surface of the abrasive layer.

[0011] Optionally, the cross-section of the cleaning plate is semi-circular, matching the outer contour of the spring.

[0012] Optionally, two connectors are provided on each of the chains. Each connector is a link formed by hinged chain links. The tails of the multiple links are all provided on the transfer seat. Inclined protective plates are provided on opposite sides of the transfer seat. The inclination of the protective plate near the outlet is the same as that of the stripping frame. A push plate is provided on the inner wall of the quenching pool near the inlet. The push plate is horizontally positioned and the projection of the protective plate in the vertical direction covers the push plate.

[0013] Optionally, two connectors are provided on each of the chains. The connectors are chain links formed by hinged chain links. The transfer seat includes a base. Inclined protective plates are provided on opposite sides of the base. The inclination of the protective plate near the outlet is the same as that of the stripping frame. The chain links are provided on the protective plates. A push plate is provided on the inner wall of the quenching pool near the inlet. The push plate is horizontally positioned and the projection of the protective plate in the vertical direction covers the push plate.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This application, by setting a frosted layer and an internal cleaning component, allows the frosted layer to abut against the outer surface of the spring as the spring rolls along the inclined peeling frame, peeling off the oxide scale from the outer surface of the spring through a cutting action. The frosted ring plate abuts against the inner wall of the spring, and moves along the spring axis when rotating, peeling off the oxide scale from the inner surface of the spring. This achieves pre-removal of the oxide scale from the outer surface of the spring, reducing the possibility of reduced quenching quality due to oxide scale adhesion after the spring enters the quenching tank. This application sets up a cleaning component so that, during the spring rolling process, the cleaning plate removes the residual oxide scale on the spring's forward surface in advance, thereby ensuring that there are no residual debris on the surface of the peeling frame that the spring contacts, thus reducing the possibility that debris will be re-adhere to the outer surface of the spring after being crushed by the spring. This application incorporates a transfer seat inside the quenching chamber. A spring rolls from the inlet and the protective plate to the base surface of the transfer seat. Subsequently, a transfer motor drives the transfer seat downwards via the transmission action of a sprocket and chain. When the transfer seat moves to the position of the push plate, the push plate interferes with the movement of the protective plate. As the protective plate descends further, the push plate acts on one side of the protective plate, causing the transfer seat to rotate towards the inside of the quenching tank. Due to the non-rigid connection of the chain links, the transfer seat is tilted as a whole. This allows the spring to slide off the surface of the base plate and the protective plate under the combined action of its own weight and the tilting guidance of the transfer seat. After detaching from the transfer seat, the spring falls into the quenching tank. The transfer seat restricts the movement path of the spring inside the quenching chamber, preventing the spring from accelerating and rolling down under gravity, thus avoiding collisions with the side walls of the quenching tank and ensuring the smooth progress of the quenching process.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0023] This application discloses a high-performance spring coil quenching transfer device.

[0024] Reference Figure 1 , Figure 2 and Figure 5 A high-performance spring coil quenching transfer device includes a quenching box 1 and a stripping frame 2. The quenching box 1 has an inlet 101 at one end near the stripping frame 2 and an outlet 102 at the other end. The top of the stripping frame 2 has a feed port 21 for the formed spring to enter. Inside the stripping frame 2, a horizontally arranged support plate 22 is slidably connected at the feed port 21. In this embodiment, a linear cylinder (not shown in the figure) is installed on the bottom surface of the stripping frame 2. The piston rod of the linear cylinder is fixedly connected to the support plate 22. The stripping frame 2 has a clearance groove (not shown in the figure) for the support plate 22 to move. The conveying device of the preceding production line conveys the formed spring to the top of the support plate 22 through the feed port 21.

[0025] Reference Figure 2 and Figure 3 The peeling frame 2 is inclined from top to bottom along the direction close to the quenching tank 1. The surface of the peeling frame 2 is covered with a frosted layer 23 along the length direction. The particle size of the frosted layer 23 gradually decreases along the direction close to the quenching tank 103. The frosted layer 23 abuts against the outer surface of the spring. The inclined surface of the peeling frame 2 is provided with an inner cleaning component 3 for removing the oxide scale inside the spring.

[0026] Reference Figure 2 and Figure 3 Specifically, the internal cleaning component 3 includes a connecting shaft 31 slidably connected to the peeling frame 2 in an inclined direction. A frosted ring plate 32 is installed at the end of the connecting shaft 31 near the feed inlet 21. The frosted ring plate 32 abuts against the inner wall of the spring. A sliding groove 24 is provided on the inner wall of the peeling frame 2 away from the feed inlet 21 in an inclined direction. An inner threaded sleeve 33 is slidably connected inside the sliding groove 24. A spiral groove 311 is provided on the surface of the connecting shaft 31 along the axial direction, which is threadedly engaged with the inner threaded sleeve 33. When the inner threaded sleeve 33 moves along the sliding groove 24, the inner threaded sleeve 33 drives the connecting shaft 31 and the frosted ring plate 32 to slide in an inclined direction. Limiting blocks 331 are provided on both sides of the inner threaded sleeve 33. A limiting groove 241 is provided on the inner wall of the sliding groove 24, which is slidably engaged with the limiting blocks 331. In the initial state, the connecting shaft 31 stays at the top of the sliding groove 24 near the bearing plate 22. The connecting shaft 31 is coaxially arranged with the spring to be quenched.

[0027] Reference Figure 3 and Figure 4The stripping frame 2 is equipped with a drive assembly 4, which includes a winch motor 41 mounted on top of the stripping frame 2. The output shaft of the winch motor 41 is coaxially and fixedly connected to a take-up shaft 42. The take-up shaft 42 extends into the sliding groove 24 and winds up a high-strength first connecting rope 43. The free end of the first connecting rope 43 is fixedly connected to the outer surface of the inner threaded sleeve 33. An outer toothed ring 44 is rotatably connected to the side of the inner threaded sleeve 33 away from the feed inlet 21. A connecting ring (not shown in the figure) is fixedly connected to the end face of the outer toothed ring 44. The inner threaded sleeve 33 has a connecting groove (not shown in the figure) that rotates with the connecting ring. The axial movement of the outer gear ring 44 is restricted by the rotational engagement of the connecting ring and the connecting groove. A limiting block 441 is fixedly connected to the inner side wall of the outer gear ring 44. A limiting groove 312 that slides with the limiting block 441 is opened on the outer surface of the connecting shaft 31 along the axial direction. The limiting groove 312 is connected to the spiral groove 311 on the connecting shaft 31. A rack plate 45 that meshes with the external gear is fixedly connected to the outer surface of the peeling frame 2 along the inclined direction.

[0028] Before quenching, the hoist motor 41 drives the winding shaft 42 to wind up the first connecting rope 43. At this time, the connecting shaft 31 stops at the top of the sliding groove 24 near the bearing plate 22. When the conveying device of the current production line conveys the spring to be quenched to the top of the bearing plate 22, the connecting shaft 31 passes through the inside of the spring, and the frosted ring plate 32 abuts against the inner wall of the spring. During quenching, the hoist motor 41 drives the take-up shaft 42 to release the first connecting rope 43. The first connecting rope 43 is slack, and the piston rod of the linear cylinder retracts, pulling the bearing plate 22 back into the peeling frame 2. Since the peeling frame 2 and the sliding groove 24 are inclined, the inner thread sleeve 33 and the connecting shaft 31 will roll along the sliding groove 24 under the action of gravity. The spring rolls along the inclined direction of the peeling frame 2. During this process, the outer surface of the spring is in continuous frictional contact with the abrasive layer 23. Through the cutting action of the particles on the surface of the abrasive layer 23, the oxide scale attached to the outer surface of the spring is peeled off. At the same time, the rolling motion of the spring is used to achieve all-round cleaning of the oxide scale on the outer surface of the spring. Meanwhile, the inner threaded sleeve 33 drives the outer toothed ring 44 to roll along the rack plate 45. The outer toothed ring 44 rotates due to meshing with the rack plate 45. Under the limiting action of the rotation limiting block 441 and the rotation limiting groove 312, the rotation torque of the outer toothed ring 44 is transmitted to the connecting shaft 31, which drives the connecting shaft 31 to rotate synchronously. It should be noted that the inner threaded sleeve 33 cannot rotate under the restriction of the limiting block 331 and the limiting groove 241. Therefore, during the rotation of the connecting shaft 31, the connecting shaft 31 will move away from the feed port 21 along the axial direction. The movement of the connecting shaft 31 drives the abrasive ring plate 32 to move axially synchronously inside the spring. Inside the spring, the abrasive ring plate 32 abuts against the inner wall of the spring. The abrasive surface of the abrasive ring plate 32 generates a continuous shearing force with the oxide scale on the inner wall of the spring. At the same time, the abrasive ring plate 32 rotates and moves axially inside the spring, thereby cleaning the oxide scale on the inner ring surface of the spring. When the connecting shaft 31 moves to the bottom of the sliding groove 24, the abrasive ring plate 32 completely exits the spring, thus avoiding interference with the subsequent rolling of the spring. At this time, the cleaned spring rolls along the peeling frame 2 to the inlet 101 under its own weight. The spring enters the quenching tank 103 through the inlet 101 to prepare for quenching treatment. The winch motor 41 drives the winding shaft 42 to wind up the first connecting rope 43. The first connecting rope 43 pulls the inner thread sleeve 33 to move along the sliding groove 24. At this time, the movement of the inner thread sleeve 33 will drive the connecting shaft 31 to move along the axial direction. When the inner thread sleeve 33 moves to the top of the sliding groove 24, the abrasive ring plate 32 moves to the side of the peeling frame 2 near the feed port 21 to facilitate the subsequent cleaning of the oxide scale of the spring.

[0029] Reference Figure 2 and Figure 3 After the oxide scale is removed from the spring, it partially accumulates on the surface of the peeling frame 2. When subsequent springs pass through the peeling frame 2, the remaining oxide scale may adhere to the outer surface of the spring, causing secondary pollution and reducing the removal effect of the oxide scale on the spring. To solve the above technical problem, a cleaning component 5 is provided on the peeling frame 2. The cleaning component 5 includes a cleaning plate 51 slidably connected in the inclined direction of the peeling frame 2. The cleaning plate 51 is parallel to the width direction of the peeling frame 2 and has a fine brush layer 52 fixedly connected to its bottom surface. The brush layer 52 abuts against the surface of the abrasive layer 23. It should be noted that the horizontal direction of the cleaning plate 51 is... The cross-section is semi-circular, matching the outer contour of the spring, and the thickness of the cleaning plate 51 allows the spring to slide through the arc surface. One end of the cleaning plate 51 is detachably connected to the outer surface of the inner threaded sleeve 33 via a connecting rod, and the other end is fixedly fitted with a moving block 53. The peeling frame 2 has a moving groove 25 on its side wall away from the sliding groove 24, which slides with the moving block 53. The end of the winding shaft 42 extends to the top of the moving groove 25 and winds up the second connecting rope 46. The free end of the second connecting rope 46 is fixedly connected to the moving block 53. In the initial state, the cleaning plate 51 is located on the side of the spring's forward surface.

[0030] Reference Figure 2 and Figure 3 An air pump 54 is installed on the peeling frame 2. An air pipe 55 is connected to the air outlet of the air pump 54. In this embodiment, the air pipe 55 is a corrugated pipe to adapt to the movement of the cleaning plate 51. An air chamber (not shown in the figure) connected to the air pipe 55 is opened inside the cleaning plate 51. Multiple air nozzles 56 are installed along the length of the forward surface of the cleaning plate 51. The air outlet direction of the air nozzles 56 is towards the surface of the peeling frame 2. All the air nozzles 56 are connected to the air chamber. A waste chip trough 26 is opened on the side of the peeling frame 2 near the inlet 101. The opening of the waste chip trough 26 is funnel-shaped. A collection box 27 connected to the waste chip trough 26 is installed at the bottom of the peeling frame 2.

[0031] As the inner threaded sleeve 33 drives the inner cleaning assembly 3 to slide down, the cleaning plate 51 slides down synchronously along the inclined direction of the peeling frame 2. At the same time, the air supply pump 54 starts and delivers high-pressure gas to the air chamber through the air pipe 55. The gas is evenly distributed to each air nozzle 56 through the air chamber and sprayed towards the surface of the peeling frame 2 through the air nozzle 56. The impact force of the high-pressure airflow blows away the oxide scale debris remaining in the gap of the abrasive layer 23 from the surface of the peeling frame 2, and at the same time breaks the adhesion between the debris and the abrasive layer 23, providing assistance for subsequent brush cleaning. At the same time, the brush layer 52 continuously slides and rubs against the surface of the peeling frame 2, cleaning the debris blown up by the air nozzle 56 and the fine debris that has not been blown away. Since the cleaning plate 51 is located on the leading surface of the spring, the cleaning plate 51 pre-cleans the oxide scale debris on the rolling path before the spring during the rolling process, ensuring that there are no residual debris on the surface of the peeling frame 2 in contact with the spring, thereby reducing the possibility that the debris will be crushed by the spring and re-adhere to the outer surface of the spring.

[0032] When the connecting shaft 31 moves to the bottom of the sliding groove 24 and the abrasive ring plate 32 completely exits the spring, the spring continues to roll along the inclined surface of the peeling frame 2 under its own gravity. At this time, the spring can slide smoothly through the semi-circular arc surface of the top surface of the cleaning plate 51, and the spring can shake slightly during this process, which helps the small amount of oxide scale debris remaining in the spring to fall off during the shaking. At the same time, the cleaning plate 51 slides to a position close to the waste chip trough 26, and the oxide scale waste chip cleaned by the cleaning component 5 falls into the collection box 27 through the waste chip trough 26, realizing the automatic collection of waste chip. Finally, the hoisting motor 41 drives the winding shaft 42 to synchronously wind up the first connecting rope 43 and the second connecting rope 46, and the inner cleaning component 3 and the cleaning component 5 rise and reset synchronously, preparing for the cleaning of the next spring.

[0033] Reference Figure 5 and Figure 6The quenching box 1 has a quenching pool 103 containing quenching oil along its length. In this embodiment, an oil inlet pipe and an oil outlet pipe are connected to the quenching pool 103. A cooling device is installed outside the quenching box 1. The oil outlet pipe and the oil inlet pipe are connected to the oil outlet and oil return port of the cooling device. The high-temperature quenching oil flows back to the external cooling device through the oil outlet pipe, and after cooling, it flows into the quenching pool 103 through the oil inlet pipe. This realizes the cooling circulation of the quenching oil and ensures that the temperature of the quenching oil is relatively stable. A transfer rack 6 is installed inside the quenching box 1 on the side near the inlet 101. The transfer frame 6 is mounted above the quenching tank 103. Both the upper and lower ends of the transfer frame 6 are rotatably connected to the inner side wall. The two sprockets 61 at the top are connected by a main shaft 63. A transfer motor 64 that drives the main shaft 63 to rotate is installed on the top of the transfer frame 6. The outer surfaces of the two sprockets 61 on the same side are fitted with chains 62. Each chain 62 has a connector installed on the opposite surface along the width direction of the transfer frame 6. The connector is a link 65 formed by hinged chain links. The tails of the four links 65 are connected to a transfer seat 7 for carrying springs.

[0034] Reference Figure 2 and Figure 3 The transfer seat 7 is U-shaped, and both ends of it are fixedly connected with inclined protective plates 71. When the transfer motor 64 is not started, the end of the protective plate 71 near the inlet 101 abuts against the inner side wall of the quenching box 1, and the inclination of the protective plate 71 is the same as that of the inclined frame of the stripping frame 2. A push plate 8 is fixedly connected to the inner side wall of the quenching pool 103 near the inlet 101. The push plate 8 is horizontally set and the projection of the protective plate 71 in the vertical direction covers the push plate 8.

[0035] Reference Figure 2 and Figure 3 The quenching box 1 is equipped with a tracked conveyor 9 that allows the spring to be transported within the quenching pool 103. The starting end of the tracked conveyor 9 is located below the transfer frame 6, and the end extends to the outside through the outlet 102. The tracked conveyor 9 is a commonly used conveying equipment in the field of spring quenching. Its specific composition and operation are not described in detail in this embodiment.

[0036] When the spring passes through the inlet 101, it rolls along the protective plate 71 to the top of the bottom plate. The protective plate 71 on the other side intercepts the spring to prevent it from directly entering the quenching tank 103. Then, the transfer motor 64 drives the main shaft 63 to rotate. The main shaft 63 drives the two sprockets 61 at the top to rotate synchronously. Through the chain 62, the lower sprocket 61 on the same side rotates synchronously in the same direction. When the chain 62 rotates, it drives the transfer seat 7 on the chain link 65 to move towards the quenching tank 103. During this process, the protective plates 71 on both sides always limit the spring to prevent the spring from shaking and falling off the transfer seat 7 during the transfer process. When the transfer seat 7 moves to the position of the push plate 8, the push plate 8 interferes with the movement of the protective plate 71. As the protective plate 71 descends further, the push plate 8 acts on one side of the protective plate 71, causing the transfer seat 7 to rotate toward the interior of the quenching tank 103. Under the non-rigid connection of the chain link 65, the transfer seat 7 is tilted as a whole, causing the spring to slide out along the surface of the base plate and the protective plate 71 under the dual action of its own weight and the tilting guidance of the transfer seat 7. After leaving the transfer seat 7, it falls into the starting end of the track conveyor 9 in the quenching tank 103. The track conveyor 9 starts, and the cyclic rotation of the track drives the spring to move along the length of the quenching tank 103. During the movement, the quenching oil absorbs the heat of the spring, realizing the quenching treatment of the spring. As the track conveyor 9 continues to run, the spring moves with the track to the outlet 102 of the quenching box 1, thus completing the entire quenching process.

[0037] The implementation principle of a high-performance spring coil quenching transfer device in this application embodiment is as follows: Before quenching, the winch motor 41 drives the winding shaft 42 to wind up the first connecting rope 43. At this time, the connecting shaft 31 stays at the top of the sliding groove 24 near the bearing plate 22. When the conveying device of the current production line conveys the spring to be quenched to the top of the bearing plate 22, the connecting shaft 31 penetrates the inside of the spring, and the frosted ring plate 32 abuts against the inner wall of the spring. During quenching, the hoist motor 41 drives the take-up shaft 42 to release the first connecting rope 43. The first connecting rope 43 is slack, and the piston rod of the linear cylinder retracts, pulling the bearing plate 22 back into the peeling frame 2. Since the peeling frame 2 and the sliding groove 24 are inclined, the inner thread sleeve 33 and the connecting shaft 31 will roll along the sliding groove 24 under the action of gravity. The spring rolls along the inclined direction of the peeling frame 2. During this process, the outer surface of the spring is in continuous frictional contact with the abrasive layer 23. Through the cutting action of the particles on the surface of the abrasive layer 23, the oxide scale attached to the outer surface of the spring is peeled off. At the same time, the rolling motion of the spring is used to achieve all-round cleaning of the oxide scale on the outer surface of the spring. Simultaneously, the inner threaded sleeve 33 drives the outer gear ring 44 to roll along the rack plate 45. The outer gear ring 44 rotates due to its engagement with the rack plate 45. Under the limiting action of the rotation limiting block 441 and the rotation limiting groove 312, the rotational torque of the outer gear ring 44 is transmitted to the connecting shaft 31, causing the connecting shaft 31 to rotate synchronously. It should be noted that the inner threaded sleeve 33 cannot rotate under the restriction of the limiting block 331 and the limiting groove 241. Therefore, during the rotation of the connecting shaft 31, the connecting shaft 31 will move away from the feed inlet 21 along the axial direction. The moving direction of the connecting shaft 31 causes the frosted ring plate 32 to move axially synchronously inside the spring. Inside the spring, the frosted ring plate 32 abuts against the inner wall of the spring, and the frosted surface of the frosted ring plate 32 generates a continuous shearing force with the oxide scale on the inner wall of the spring. At the same time, the frosted ring plate 32 rotates and moves axially inside the spring, thereby achieving all-round cleaning of the oxide scale on the inner surface of the spring. This reduces the possibility of reduced quenching quality due to oxide scale adhesion after the spring enters the quenching pool 103, thereby improving the quenching quality of the spring.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
