Description

Technical Field

[0001] This invention relates to the field of metal component cooling technology, specifically to a special cooling device for heat treatment of large titanium alloy metal components. Background Technology

[0002] Large titanium alloy metal components (such as aerospace structural parts and aerospace shells) require rapid and uniform cooling after high-temperature heat treatment (such as solution treatment) to fix the ideal metallographic structure and obtain the required mechanical properties. Currently, spray cooling is the most common cooling method in the industry. This involves using a water pump to deliver a cooling medium (such as deionized water or a special quenching fluid) to a nozzle, spraying it from top to bottom onto the surface of a stationary suspended or placed component. Cooling is achieved through convective heat transfer between the coolant and the component surface. This process has become the mainstream choice due to its relatively simple system and adjustable cooling rate.

[0003] However, traditional unidirectional spray cooling methods have significant limitations. Firstly, the nozzles are typically fixed above the component, limiting the spray angle and range. This makes them unsuitable for the complex surface structures of large components, resulting in significant cooling dead zones on the bottom, sides, and recessed areas. The coolant can only cover the upper surface, while the lower and sides rely on indirect heat conduction for cooling, leading to significant differences in cooling rates across different parts of the component. Secondly, fixed nozzles cannot adjust the spray direction according to the component's shape. Even with multiple nozzle arrays, it's difficult to achieve comprehensive and sufficient contact between the coolant and the component surface. Some areas may not receive sufficient coolant or have insufficient residence time, further exacerbating the uneven cooling phenomenon. These factors collectively contribute to the non-uniformity of the cooling process.

[0004] The aforementioned uneven cooling can generate enormous unbalanced thermal stress within the component, easily inducing defects such as deformation and cracking. It also leads to inconsistencies in the microstructure across different parts of the component, severely impacting the dimensional accuracy, fatigue performance, and service reliability of the final product. Especially for large, complex, and valuable titanium alloy critical components, a single spray cooling method is insufficient to meet their high-quality, consistent heat treatment cooling requirements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dedicated cooling device for the heat treatment of large titanium alloy metal components, which solves the problem of uneven cooling caused by a single spray cooling method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a special cooling device for heat treatment of large titanium alloy metal components, comprising a cooling pool, a water storage pool, and a column. A water pump is fixedly installed inside the water storage pool, and a water supply pipe is fixedly connected to the output end of the water pump. A fixed pipe is detachably connected to the outer wall of the water supply pipe. The outer wall of the fixed pipe is fixedly connected to the outer wall of the column. At least one set of spraying components is fixedly connected to the outer wall of the fixed pipe. The cooling pool is located below the spraying components. A driving device is fixedly installed on the outer wall of the cooling pool. The output end of the driving device passes through the outer wall of the cooling pool and is fixedly connected to a rotating shaft. A fixed frame is fixedly connected to the outer wall of the rotating shaft, and the outer wall of the rotating shaft is rotatably connected to the inside of the cooling pool.

[0007] The above solution achieves precise top-to-bottom spraying by mounting spray components on fixed pipes supported by columns. At the same time, the driving device on the outer wall of the cooling pool drives the rotating shaft and fixed frame to swing back and forth, causing the components to dynamically adjust their posture, thus completely avoiding the dead zone problem of traditional cooling. The cooling pool has both spray receiving and bottom immersion functions, allowing the residual heat at the bottom of the components to dissipate quickly through immersion cooling, forming a dual cooling mode of spraying and immersion, which significantly improves cooling efficiency and uniformity.

[0008] Preferably, the spray assembly includes a corrugated pipe, one end of which is fixedly connected to the outer wall of a fixed pipe, and the other end of which is fixedly connected to a spray head.

[0009] Preferably, a slide rail is fixedly connected to the outer wall of the fixed frame, a slider is slidably connected inside the slide rail, a groove is provided inside the slide rail, the outer wall of the slider is slidably connected inside the groove, and a clamping plate is fixedly connected to the upper surface of the slider.

[0010] Preferably, a slide rail two is fixedly connected to the lower surface of the fixed frame, a T-slot is provided inside the slide rail two, a counterweight is slidably connected inside the slide rail two, the counterweight is combinable, one end of a connecting rod is rotatably connected to the outer wall of the counterweight, and the other end of the connecting rod is rotatably connected to the lower surface of the slider.

[0011] Preferably, a filter plate is fixedly installed on the inner wall of the cooling pool, and the filter plate is inclined downward.

[0012] Preferably, a collection chamber is fixedly connected to the outer wall of the cooling pool, the collection chamber is connected to the cooling pool, and a filter plate two is fixedly installed inside the collection chamber, the filter plate two being inclined upward and pointing towards the collection chamber.

[0013] Preferably, a drain outlet is provided on the lower side of the cooling pool.

[0014] Preferably, a drain pipe is fixedly connected to the outer wall of the middle part of the cooling pool, the drain pipe communicates with the interior of the cooling pool, a turbine housing is fixedly connected to the outer wall of the drain pipe, a return water pipe is fixedly connected to the outer wall of the turbine housing, and the outer wall of the return water pipe is detachably connected to and communicates with a water storage tank.

[0015] Preferably, an impeller is rotatably connected inside the turbine housing, a drive shaft is fixedly connected to the outer wall of the impeller, a transmission mechanism is provided on the outer wall of the drive shaft, the transmission mechanism is connected to an overrunning clutch, the transmission mechanism includes a belt, chain or gear, and the overrunning clutch is located on the outer wall of the shaft.

[0016] Preferably, a filter plate three is fixedly installed inside the drain pipe, and a scraper is rotatably connected to the outer wall of the filter plate three. The scraper is fixedly connected to the outer wall of the drive shaft, and the outer wall of the drive shaft passes through the filter plate three and is rotatably connected to the filter plate three.

[0017] Working principle: First, after the equipment is started, the water pump in the storage tank pumps the coolant through the water pipe to the fixed pipe, and then sprays it evenly onto the surface of the large titanium alloy metal component through the spray assembly connected by the corrugated pipe. The component is supported by the fixed frame and is driven by the drive device to rotate the shaft back and forth, so that the spray cooling covers the entire surface of the component and avoids dead corners. At the same time, the bottom of the component is immersed in the coolant stored in the cooling tank, realizing synchronous cooling from top to bottom, ensuring that the component cools down quickly and evenly after heat treatment.

[0018] When the component is placed on the fixed frame, the counterweight slides down the slide rail under the influence of gravity. This, via a connecting rod, pushes the sliders on both sides to slide towards the center along the slide rail, causing the clamping plate to automatically clamp the component. During the swinging process, the centrifugal force generated by the counterweight is superimposed on gravity, further enhancing the clamping force and adapting to the changes in component cooling and contraction, ensuring stability during swinging. The counterweight adopts a combinable design, allowing users to adjust the clamping force by adding or removing counterweights.

[0019] The swinging of the fixed frame causes the coolant to flow, where suspended dust and debris are intercepted by an inclined filter plate in the cooling pool and settle to the bottom. Simultaneously, floating debris propelled by the water flow enters the collection chamber, where it is trapped by an upwardly inclined filter plate, while the water flows back through the filter plates to the cooling pool. This design effectively prevents impurities from adhering to component surfaces or clogging the system; maintenance only requires periodic cleaning of the filter plates and collection chamber.

[0020] The drain pipe in the middle of the cooling pool guides the coolant into the turbine housing, driving the impeller to rotate. The impeller is connected to a scraper via a drive shaft, which rotates and scrapes away impurities on three surfaces of the filter plate, preventing the mesh from clogging. The water flows back to the storage tank through the return pipe for reuse. The turbine housing is powered by the oscillation of the shaft, which is converted into unidirectional rotation by an overrunning clutch and then transmitted to the impeller through a transmission mechanism, thus achieving energy-saving water resource recycling and automatic maintenance.

[0021] This invention provides a dedicated cooling device for heat treatment of large titanium alloy metal components. It offers the following advantages: 1. This invention utilizes a combination of top spraying of coolant and bottom immersion in a cooling pool to achieve all-around cooling of large titanium alloy components, enabling rapid heat removal. The added drive device causes the component to oscillate back and forth, allowing the coolant to impact all surfaces of the component, effectively preventing deformation, cracking, or differences in microstructure and properties caused by uneven cooling, and significantly improving the overall quality and reliability of the heat-treated component.

[0022] 2. The fixing frame of this invention adopts a purely mechanical clamping mechanism consisting of a counterweight, connecting rod, and slider. The clamping force is automatically provided by the gravity of the counterweight, resulting in a simple and reliable structure. When the component cools and contracts, the counterweight can adaptively slide down to maintain the clamped state. When the fixing frame swings, the centrifugal force generated by the counterweight is superimposed on the gravity, further increasing the clamping force during the swing process. This effectively prevents the component from loosening or shifting during dynamic cooling, ensuring operational safety and process stability.

[0023] 3. The cooling pool of this invention is connected to the storage tank via a drain pipe, turbine housing, and return water pipe, forming a closed coolant circulation system. Utilizing the power of the drive shaft, the reciprocating oscillation is converted into unidirectional rotation of the impeller through an overrunning clutch and transmission mechanism, thereby actively pumping the liquid in the cooling pool back to the storage tank. This design cleverly recovers and utilizes the equipment's own kinetic energy to drive liquid circulation, significantly reducing dependence on external water pumps and overall energy consumption, achieving energy conservation and environmental protection.

[0024] 4. This invention features a filter plate three at the drain pipe inlet, with a drive shaft driving a scraper to rotate. When the impeller is driven, the synchronously rotating scraper continuously removes impurities accumulated on the filter plate surface, preventing mesh clogging. This self-cleaning design ensures long-term unobstructed water circulation, significantly reducing the frequency of downtime for cleaning due to filter clogging, and lowering equipment maintenance workload and costs.

[0025] 5. The inclined filter plate one in the cooling pool can intercept and settle larger impurities in the water flow; the filter plate two in the collection chamber can separate and collect floating objects on the water surface; and the filter plate three at the drain pipe further filters fine particles. This combined filtration system can keep the coolant clean for a long time, prevent impurities from adhering to the surface of high-temperature components, affecting the cooling effect or causing pollution, and extend the service life of the coolant.

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention aims to solve the problems of uneven cooling, low efficiency, and high levels of impurities in the coolant after heat treatment of large titanium alloy metal components. Its core technology lies in constructing a dynamic, adaptive, and energy-efficient cooling system. The equipment employs a combination of spraying and immersion methods, using a drive device to cause the fixed frame supporting the component to swing back and forth, completely eliminating cooling dead zones and ensuring uniform temperature. The clamping mechanism innovatively utilizes counterweights and connecting rods, which not only adapt to the component's cooling contraction but also enhance the clamping effect through centrifugal force during swinging, ensuring process stability. For coolant management, a sedimentation, floating, and recirculation filtration system is designed, and a scraper linked to the drive shaft automatically cleans the filter screen, ensuring coolant cleanliness. Particularly noteworthy is the ingenious recovery of the mechanical energy from the fixed frame's swinging motion. Through an overrunning clutch and transmission mechanism, the reciprocating motion is converted into unidirectional rotation, driving an impeller to assist in coolant return, significantly reducing system energy consumption.

[0030] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a special cooling device for heat treatment of large titanium alloy metal components, including a cooling pool 1, a water storage pool 2, and a column 3. A water pump 4 is fixedly installed inside the water storage pool 2. A water supply pipe 5 is fixedly connected to the output end of the water pump 4. A fixed pipe 6 is detachably connected to the outer wall of the water supply pipe 5. The outer wall of the fixed pipe 6 is fixedly connected to the outer wall of the column 3. At least one set of spraying components is fixedly connected to the outer wall of the fixed pipe 6. The cooling pool 1 is located below the spraying components. A driving device 9 is fixedly installed on the outer wall of the cooling pool 1. The output end of the driving device 9 passes through the outer wall of the cooling pool 1 and is fixedly connected to a rotating shaft 10. A fixing frame 11 is fixedly connected to the outer wall of the rotating shaft 10. The outer wall of the rotating shaft 10 is rotatably connected to the inside of the cooling pool 1.

[0031] Specifically, this application is used for cooling large titanium alloy metal components. The cooling tank 1, the water storage tank 2, and the column 3 are all fixed to the ground using expansion bolts. The water storage tank 2 stores coolant, such as industrial pure water or a special cooling medium. The water storage tank 2 draws coolant from the water pump 4 installed inside. The output end of the water pump 4 is fixedly connected to a water delivery pipe 5 via a flange, and the coolant is then pumped out through the water pump 4 into the water delivery pipe 5. The outer wall of the water delivery pipe 5 is connected to the fixed pipe 6 using existing detachable connection methods, such as snap-fit ​​connections or flange connections. Snap-fit ​​connections are suitable for quick disassembly and maintenance, while flange connections ensure sealing performance and prevent coolant leakage. Users can choose according to their actual application scenario. The coolant is sprayed downwards through the fixed pipe 6 by a spray assembly. The column 3 supports the fixed pipe. 6. Large titanium alloy metal components are placed on the upper surface of the fixed frame 11. The spray assembly cools the large titanium alloy metal components by spraying coolant onto them. This application further adds a drive device 9 to the outer wall of the cooling pool 1. The drive device 9 can be a geared motor or a rotary cylinder. The swing angle can be adjusted by a controller, which drives the rotating shaft 10 to rotate. The rotation mode is reciprocating swing. The cooling pool 1 supports the rotation of the rotating shaft 10. The rotating shaft 10 drives the fixed frame 11 to swing back and forth. In conjunction with the spray assembly, it can avoid the existence of cooling dead corners for large components. At the same time, the cooling pool 1 itself can store coolant for the spray assembly to spray from top to bottom. There may be residual heat at the bottom of the large titanium alloy metal components. Therefore, the bottom of the components can be immersed in the coolant inside the cooling pool 1 to ensure sufficient and rapid cooling.

[0032] Currently, all existing drive devices 9 can be equipped with a self-locking structure to ensure that the fixed frame 11 is stopped in a horizontal position. In addition, a limiting protrusion can be added to the inner wall of the cooling pool 1 near the rotating shaft 10 and the fixed frame 11 to prevent the fixed frame 11 from tipping over.

[0033] Please see the appendix Figure 1 The spray assembly includes a corrugated pipe 7, one end of which is fixedly connected to the outer wall of the fixed pipe 6, and the other end of which is fixedly connected to a nozzle 8.

[0034] Specifically, in this application, the fixed pipe 6 and the nozzle 8 are connected by a corrugated pipe 7. The corrugated pipe 7 allows the operator to adjust the angle of the nozzle 8 according to the specific shape and position of the component. The coolant inside the fixed pipe 6 is sprayed out from the drive device 9 through the corrugated pipe 7. The water pressure of the nozzle 8 is provided by the water pump 4. The nozzle 8 can be a fan-shaped nozzle or an atomizing nozzle.

[0035] Please see the appendix Figure 2 - Appendix Figure 4The outer wall of the fixed frame 11 is fixedly connected to a slide rail 12, and a slider 13 is slidably connected inside the slide rail 12. A groove 14 is provided inside the slide rail 12, and the outer wall of the slider 13 is slidably connected inside the groove 14. A clamping plate 15 is fixedly connected to the upper surface of the slider 13. The lower surface of the fixed frame 11 is fixedly connected to a slide rail 16, and a T-slot is provided inside the slide rail 16. A counterweight 17 is slidably connected inside the slide rail 16, and one end of a connecting rod 18 is rotatably connected to the outer wall of the counterweight 17. The other end of the connecting rod 18 is rotatably connected to the lower surface of the slider 13.

[0036] Specifically, the fixing frame 11 is a frame structure. In this application, clamping plates 15 are provided to fix large titanium alloy metal components. A set of clamping plates 15 slides from both sides toward the center to clamp and fix the large titanium alloy metal components. The number of sets of clamping plates 15 can be set according to specific needs. When fixing large titanium alloy metal components, the metal components are placed on the upper surface of the fixing frame 11. The clamping force is provided by the counterweight 17. The counterweight 17 slides downward under the action of gravity, thereby driving the connecting rods 18 on both sides to rotate. The connecting rods 18 on both sides drive the sliders 13 on both sides to slide toward the center to clamp the metal components. Considering the possibility of volume shrinkage of the metal components when cooling, the counterweight 17 in this application can be T-shaped inside the slide rail 16. The counterweight 17 can maintain a clamped state when the metal component retracts. In this application, the slider 13 is embedded in the slide groove 14. The slide rail 12 and the slide groove 14 are provided to support the slider 13 to slide. The slide rail 16 and the T-slot are provided to support the counterweight 17 to slide. In this application, the counterweight 17 is combinable, that is, the bottom of the T-slot is completely open. Multiple sets of counterweights 17 can be connected by bolts to change the counterweight of the counterweight 17, thereby changing the clamping force. In addition, the counterweight 17 can cooperate with the swinging motion to maintain an appropriate clamping force. When the fixed frame 11 starts to swing, the counterweight 17 will be subjected to centrifugal force. The centrifugal force combined with gravity can increase the clamping force during swinging and ensure the stability of the metal component during swinging.

[0037] When removing or before placing the metal component, it can be unlocked by pulling the counterweight 17 upwards to slide it up, or by pulling the slider 13 on one side outwards. A limit pin can also be set to fix the counterweight in the maximum open state. The above methods can be achieved with existing technology and will not be described in detail.

[0038] Please see the appendix Figure 5 A filter plate 19 is fixedly installed on the inner wall of the cooling pool 1, and the filter plate 19 is inclined downward.

[0039] Specifically, filter plates 19 are added to the inner walls of both sides of the cooling pool 1. During the reciprocating swing of the fixing frame 11, the coolant in the cooling pool 1 flows, and dust, debris, and other impurities carried in the flowing coolant are intercepted by the filter plates 19. Because the filter plates 19 are inclined downwards, impurities settle to the bottom of the cooling pool 1 under gravity, preventing them from being stirred up by the water flow and adhering to the surface of the components, thus affecting the cooling effect. The filter plates 19 can be fixed with bolts, facilitating regular disassembly and cleaning by the user, making maintenance simple and convenient.

[0040] Please see the appendix Figure 5 A collection chamber 20 is fixedly connected to the outer wall of the cooling pool 1. The collection chamber 20 is connected to the cooling pool 1. A filter plate 21 is fixedly installed inside the collection chamber 20. The filter plate 21 is inclined upward and points towards the collection chamber 20.

[0041] Specifically, a collection chamber 20 is further added to collect floating objects. When the fixing frame 11 swings, it pushes the water flow to both sides. A filter plate 21 is added at the connection between the collection chamber 20 and the cooling pool 1. When the water flow and floating objects are pushed into the interior of the collection chamber 20, the water flow passes through the filter plate 21 and flows back into the interior of the cooling pool 1 because the filter plate 21 is tilted upward. The floating objects are left inside the collection chamber 20.

[0042] Please see the appendix Figure 7 A drain outlet 22 is provided on the lower side of the cooling pool 1.

[0043] Specifically, the drain outlet 22 is set on the lower side of the cooling pool 1 to discharge the water and impurities at the bottom. The drain outlet 22 can be set on both sides of the cooling pool 1 at the same time, and the valve on the drain outlet 22 can be opened directly according to the actual working conditions, or the pipe can be connected to discharge directly into the drainage well.

[0044] Please see the appendix Figure 1 A drain pipe 23 is fixedly connected to the outer wall of the middle part of the cooling pool 1. The drain pipe 23 connects to the interior of the cooling pool 1. A turbine housing 24 is fixedly connected to the outer wall of the drain pipe 23. A return water pipe 25 is fixedly connected to the outer wall of the turbine housing 24. The outer wall of the return water pipe 25 is detachably connected to the water storage pool 2 and communicates with the water storage pool 2.

[0045] Specifically, to reduce water waste, a drain pipe 23 is added in the middle of the cooling pool 1, through which water can flow back into the water storage pool 2 via the drain pipe 23, the turbine housing 24, and the return water pipe 25.

[0046] Please see the appendix Figure 6 - Appendix Figure 8The turbine housing 24 is rotatably connected to an impeller 26. The outer wall of the impeller 26 is fixedly connected to a drive shaft 27. The outer wall of the drive shaft 27 is provided with a transmission mechanism 28. The transmission mechanism 28 is connected to an overrunning clutch 29. The transmission mechanism 28 can be a belt, chain or gear. The overrunning clutch 29 is provided on the outer wall of the rotating shaft 10.

[0047] Specifically, an impeller 26 is added inside the turbine housing 24 to assist in water pumping. The reciprocating rotation is adjusted to unidirectional rotation via an overrunning clutch 29. The overrunning clutch 29 uses existing technology, such as a roller type: the clutch consists of an outer ring, an inner ring, rollers, and a spring, with the rollers located within a wedge-shaped groove. When the inner ring's input end rotates relative to the outer ring's output end in the driving direction, the rollers are squeezed into the narrow part of the wedge-shaped groove, wedging the inner and outer rings tightly, and power is transmitted. When the inner ring rotates in the opposite direction, or the outer ring rotates faster than the inner ring, the rollers are pushed back to the wider part of the wedge-shaped groove, disengaging the inner and outer rings and achieving unidirectional transmission or "overrunning." The outer wall of the overrunning clutch 29 can be fixedly installed on the inner wall of the cooling pool 1. The overrunning clutch 29 then drives the drive shaft 27 to rotate via a transmission mechanism 28, thereby driving the impeller 26 to rotate. The transmission mechanism 28 can be of multiple existing types. When using a belt system, pulleys are installed on the outer walls of the overrunning clutch 29 and the drive shaft 27, with a belt connecting the pulleys for transmission.

[0048] Please see the appendix Figure 9 - Appendix Figure 10 A filter plate 30 is fixedly installed inside the drain pipe 23. A scraper 31 is rotatably connected to the outer wall of the filter plate 30. The scraper 31 is fixedly connected to the outer wall of the drive shaft 27. The outer wall of the drive shaft 27 passes through the filter plate 30 and is rotatably connected to the filter plate 30.

[0049] Specifically, a filter plate 30 is further added to filter the water entering the drain pipe 23. At the same time, a scraper 31 is fixedly connected to the outer wall of the drive shaft 27. When the drive shaft 27 rotates, it drives the scraper 31 to rotate synchronously. The scraper 31 moves in a circular motion along the surface of the filter plate 30 to scrape off the fine impurities attached to the mesh of the filter plate 30. The scraped impurities fall to the bottom of the cooling pool 1 under the action of gravity. This structure can effectively prevent the filter plate 30 from being blocked by impurities, thus ensuring the stable flow of the water circulation system. It also eliminates the need for users to frequently disassemble and clean the filter plate 30, reducing maintenance workload.

[0050] The workflow of one embodiment of the present invention is as follows: After the large titanium alloy component undergoes high-temperature solution treatment in the heat treatment furnace, it is smoothly removed by a high-temperature resistant lifting device and quickly transported along the shortest path to the top of a dedicated cooling device. The operator precisely lifts it onto the fixed frame 11 of the device. At this time, the slider 13 and the clamping plate 15 are in the maximum open state. The limit pin is removed, and the counterweight 17 under the fixed frame 11 automatically slides down under the action of gravity. Through the linkage mechanism 18, it drives the clamping plates 15 on both sides to move inward synchronously, firmly and adaptively clamping the high-temperature component.

[0051] Once the component is in place, the cooling process begins immediately. Water pump 4 in the water tank 2 pumps coolant into the fixed pipes 6 on the column 3, and then through the multi-directionally adjustable corrugated pipes 7 and nozzles 8, forming a uniform spray curtain covering the upper surface and sides of the component. Simultaneously, the drive unit 9 starts working, causing the fixed frame 11 and the component to reciprocate at a controlled angle above the liquid surface in the cooling tank 1. This eliminates the cooling dead zones of traditional static spraying, allowing the coolant to impact every complex contour and recessed area of ​​the component.

[0052] While the component is being oscillated for cooling, the lower half is immersed in the coolant stored in cooling pool 1, forming a three-dimensional cooling mode of top spraying and bottom immersion, which greatly improves heat exchange efficiency. During the cooling process, the equipment's built-in multi-stage filtration system operates simultaneously: the inclined filter plate 19 in cooling pool 1 intercepts and settles large particles of impurities; floating objects carried by the water flow are guided into collection chamber 20 for interception; and the precision filter plate 30 at the inlet of the return water pipe 25 is cleaned in real time by the rotating scraper 31 to prevent clogging.

[0053] When the component temperature sensor detects the endpoint temperature required by the process, the system automatically stops spraying and oscillation. The fixing frame 11 returns to horizontal and locks, the clamping mechanism is released, and the component that has been cooled evenly and whose deformation is controlled can be lifted out and enter the next process, completing the entire logical closed loop from high-temperature furnace exit to high-quality cooling.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
