Description

Technical Field

[0001] This invention relates to the technical field of vortex plate solution furnaces, and more particularly to an aluminum vortex plate rapid solution furnace and an aluminum vortex plate solution method. Background Technology

[0002] Scroll compressors are a new type of energy-saving, material-saving, and low-noise positive displacement compressor. Their working principle utilizes the relative revolution of moving and stationary scroll plates to create a continuous change in a closed volume, thereby compressing gas. They are mainly used in air conditioning refrigeration, general gas compression, and in automotive engine turbochargers and vacuum pumps, and can largely replace traditional medium and small reciprocating compressors. Currently, the moving and stationary plates of scroll compressors are produced using multiple casting methods within a single mold. However, aluminum products obtained through casting also have certain defects, such as significant internal stress and a relatively loose microstructure, making it difficult to meet requirements in terms of strength and density. Therefore, a series of heat treatments are necessary, such as solution treatment, quenching, and aging treatment. The existing solid melting furnace has a feed inlet on one side and a discharge outlet on the other. Liftable and closed doors are installed at the openings on both sides. The feed inlet is used to hold the material racks of moving and stationary plates. After entering, the material is closed by the closed door and heated and kept warm. After the heat preservation is completed, the material comes out through the discharge outlet and enters a lifting frame. After the lifting frame, it enters the water tank at the bottom for water cooling. The time from when the aluminum alloy is taken out of the furnace to when it is submerged in water is relatively long, and there is still room for further improvement in the microstructure of the aluminum alloy.

[0003] A search revealed that CN116732305A discloses a solid solution furnace with a furnace door at the bottom, in which a chain rope is installed for feeding and unloading. During the unloading process, aluminum alloy enters the solid solution box, and steam enters the furnace, corroding the furnace structure. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to prevent steam from entering the furnace and corroding the internal structure during water cooling. The inventors have derived the technical solution of this invention through practice and summary. An opening is set at the bottom of the solid solution furnace, and the water cooling box is located at the bottom of the opening. After the aluminum alloy is heated and kept warm, the aluminum alloy is water cooled immediately, shortening the time from the furnace to the water cooling. At the same time, a steam overflow hood is used to prevent water vapor from entering the furnace. The hook body and guide hook structure are used for adaptive feeding and adaptive rapid unloading when the bottom opening is opened.

[0005] The specific technical solution is as follows:

[0006] A rapid solution treatment furnace for aluminum scroll plates includes a material rack, a feeding mechanism, a water-cooled box, and a furnace body, and further includes:

The top of the groove is a hook area, which includes a feeding area, a hook area, and a discharging area. The bottom depth of the feeding area is greater than the bottom depth of the discharging area. The depth of the feeding area gradually decreases from the bottom to the top and suddenly increases at the top. The depth of the feeding area gradually decreases from the top towards the side closer to the hook area and suddenly increases at the hook area. The depth of the discharging area gradually increases from the top towards the side closer to the hook area. The depth of the top of the discharging area first becomes level with the bottom and then gradually decreases, suddenly increasing at the intersection with the feeding area.

[0014] In a preferred embodiment, the opening and closing plate includes:

[0015] The motherboard has ear plates on both sides at the bottom, and the ear plates have guide structures.

[0016] The guide plate is provided in two sets, which are used to limit the direction of the main board opening and closing the bottom opening of the furnace body.

[0017] The sub-plate is installed between the two ear plates. An elastic body is provided between the sub-plate and the main plate. A guide body is provided on the side of the sub-plate. The guide body is adapted to the guide structure for installation.

[0018] The support plate is located diagonally below the main board and is used to slide and support the main board. The support plate is fixed on the opposite side of the guide plate.

[0020] The driven rod assembly has hinged ends, which are connected to the sub-plate and the drive rod respectively.

[0021] In a preferred embodiment, the guide structure includes a lifting section and a vertical section. The lifting section is used to guide the oblique sub-plate, and the vertical section is suitable for guiding the vertical sub-plate.

[0025] The lifting rod has hinged ends, which are connected to the sliding plate and the door panel respectively.

[0026] In a preferred embodiment, a flexible load-bearing structure is installed inside the water-cooled box. The flexible load-bearing structure includes spring damping columns and a load-bearing plate, with the load-bearing plate installed inside the water-cooled box via the spring damping columns.

[0027] A solution treatment method for an aluminum scroll disk, comprising the following steps:

[0028] Feeding:

[0029] The material rack carrying the aluminum vortex disc workpiece is carried by the feeding mechanism and moved to the bottom of the furnace body opening. The feeding mechanism is a lifting platform. The movable pin enters the groove and enters the top feeding area along the groove, and finally enters the hook area. During the feeding process, the end of the circulating fan blade shaft enters the spline joint to complete the fit. Then the flow guide structure is pressed down and the sealing plate opens the circulation hole.

[0030] Solution treatment:

[0031] The drive rod drives the main plate to approach each other between the two guide plates via the driven rod. When the two main plates contact each other, the auxiliary plate approaches each other along the lifting section and pulls the elastic body. Finally, it passes through the vertical section to vertically level the space between the two main plates and moves upward together with the main plates to seal the bottom opening of the furnace body. The heating structure inside the furnace body starts to work. The drive motor drives the circulating fan shaft and fan blades to rotate. After the temperature inside the furnace rises to 500±50℃, it is heat preservation treatment.

[0032] cool down:

[0033] The drive rod drives the two sub-plates and the main plate to continue moving upward through the driven rod group, pushing the material rack. The movable pin of the hook body on the side of the material rack enters the top of the unloading area from the hook area. The bottom of the material rack is supported on the sub-plate and the main plate. The movable pin enters the unloading area from the hook area and moves downward along the unloading area.

[0034] The drive rod, via the driven rod assembly, rapidly lowers two auxiliary plates, two main plates, and the material rack. The main plates and auxiliary plates first move downwards, then to the sides, opening the opening at the bottom of the furnace. After the main plates descend to the support plate, the main plates and auxiliary plates move to the sides. After opening the bottom opening, the main plates first detach from the bottom of the material rack. Under the action of the elastic body, the main plates rise relative to the auxiliary plates and press their sides against the sides of the material rack. Subsequently, the auxiliary plates support the material rack as it descends. As the auxiliary plates continue downwards, they move together to the sides, while the compression of the elastic body is gradually released. When the auxiliary plates are completely detached from the material rack, the material rack... The steam overflow cover falls instantly into the water-cooled box, while the bottom of the circulating fan shaft detaches from the bottom of the guide structure. The sealing plate seals the circulation holes via elastic columns. When the steam overflow cover is supported on the sub-plate, the main plate is pressed and fixed to the side of the steam overflow cover by the inclined structure under the action of the elastic body. The material rack and the aluminum scroll plate workpiece on it are cooled to below 100°C in the water-cooled box. The drive rod continues to drive the two sub-plates away from each other through the driven rod group until the steam overflow cover is completely separated from the sub-plate. The material rack falls onto the bearing plate and the impact force is reduced by the spring damping column.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. For the first time, a steam overflow hood is used on the top of the material rack. After the aluminum alloy workpiece is submerged in the water-cooled box, the steam overflow hood prevents steam from entering the furnace and protects the furnace structure from corrosion.

[0037] 2. A left-right opening and closing structure is adopted at the bottom of the furnace body. For the first time, the main board and sub-board of the opening and closing structure are used to seal the bottom opening, support the material rack when the opening is opened, and support the material rack after it automatically falls. When supporting the material rack, the main board, through the action of the elastic body and the inclined structure, seals the steam overflow hood of the material rack. When the size of the steam overflow hood is smaller than the opening size, it further ensures that the steam inside the steam overflow hood rises into the furnace. When the size of the steam overflow hood is equal to the opening size, after the opening is opened, there is no need to set up a main board and sub-board; only a single plate structure is needed. The steam overflow hood will quickly fall into the water cooling box for rapid water cooling, and the steam overflow hood will block the steam at the bottom of the furnace to prevent steam from entering the furnace.

[0038] 3. This design is the first to adopt an adaptive feeding and rapid unloading concept. A guide hook structure is set inside the furnace body. The feeding mechanism lifts the material rack, and the guide hook structure, in conjunction with the hooks on the material rack, automatically hooks the material after feeding, thus completing adaptive feeding. When unloading, the opening and closing structure first moves upward to bring the hooks on the material rack into the unloading area. The material rack then moves downward as the bottom opening of the opening and closing structure opens rapidly, and the material rack falls quickly. The falling time is generally controlled between 0.5 and 1.5 seconds. In specific implementation, the inventors prefer to control it between 0.8 and 1.2 seconds, while most existing equipment takes more than 15 seconds. Therefore, this solution can effectively shorten the water cooling time after exiting the furnace, improve the strength and hardness of the aluminum alloy, reduce grain boundary sensitivity, and make the structure more uniform.

[0039] 4. This invention is the first to employ an active opening and closing structure consisting of a sealing plate and elastic columns on a steam overflow hood. Because the steam overflow hood can hinder uniform temperature distribution, circulation holes are incorporated into it to overcome this problem. After loading, the spline structure of the circulation fan shaft end and the guide structure adapts, opening the sealing plate. During heating, the drive motor rotates the fan blades, and the airflow is evenly distributed within the steam overflow hood via the guide structure, resulting in a more uniform temperature distribution inside and outside the hood. However, the presence of circulation holes can cause steam overflow when water-cooling the scroll plate workpiece. Therefore, a sealing plate and elastic column are incorporated; during unloading, the sealing plate seals the circulation holes via the elastic columns, preventing steam from passing through. This active opening and closing structure is the inventor's first solution to the steam overflow problem, demonstrating strong practicality, advancement, and originality.

[0040] 5. After cooling is complete, the sub-plate or door panel will detach from the material rack, and the material rack and the scroll plate workpiece on it will fall onto the support plate. Spring damping columns are set at the bottom of the support plate to reduce the impact of the material rack on the water cooling box. At the same time, through holes can be set on the support plate to reduce the impact while allowing the low-temperature water at the bottom to flow upward, thus completing the rapid cooling process.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0056] Example 1, such as Figure 1 As shown, an aluminum scroll plate rapid solution furnace includes a material rack 1, a feeding mechanism 2, a water-cooled box 3, and a furnace body 4, and further includes:

[0057] Material rack 1, on which a steam overflow cover 11 and a hook 12 are installed;

[0058] like Figure 12 As shown, the height of the middle part of the steam overflow cover 11 is greater than the height of the edge. The top of the steam overflow cover 11 has evenly distributed circulation holes 111. A sealing plate 112 is installed at the circulation holes 111. A flow guiding structure 113 is provided on the top of the sealing plate 112. An elastic column 114 is provided on the outer side of the sealing plate 112. Multiple elastic columns 114 are provided and evenly distributed on the outer side of the flow guiding structure 113. A spline joint 115 is rotatably installed on the top of the flow guiding structure 113.

[0059] like Figure 12 As shown, the flow guiding structure 113 is provided with multiple flow guiding grooves that are circumferentially and equally spaced to guide the airflow in a vortex.

[0060] like Figure 1 As shown, a drive motor 41 is installed on the top of the furnace body 4, and a circulating fan shaft 42 is installed at the output end of the drive motor 41. The bottom end of the circulating fan shaft 42 is inserted into the spline joint 115. Blades are installed on the circulating fan shaft 42, and the projection of the blades on the horizontal plane is located in the circulating hole 111.

[0061] like Figure 11 As shown, the hook 12 is rotatably mounted on the side of the material rack 1, and a torsion spring is provided at the rotation node. A guide post 121 is provided on the top of the hook 12. The guide post 121 is adapted to the guide hook structure. A blind hole 122 is provided at the end of the guide post 121. A spring and a movable pin 123 are installed in the blind hole 122. The movable pin 123 is flexibly installed in the blind hole 122 by the spring and is partially exposed.

[0062] like Figure 2 and Figure 3As shown, the guide hook structure includes a groove 43 disposed on the inner wall of the furnace body 4. The top of the groove 43 is a hook area 44. The hook area 44 includes a feeding area 441, a hook area 442, and a discharging area 443. The bottom depth of the feeding area 441 is greater than the bottom depth of the discharging area 443. The depth of the feeding area 441 gradually decreases from the bottom to the top and suddenly increases at the top. The depth of the feeding area 441 gradually decreases from the top towards the side closer to the hook area 442 and suddenly increases at the hook area 442. The depth of the discharging area 443 gradually increases from the top towards the side closer to the hook area 441. The depth of the top of the discharging area 443 towards the bottom is first level and then gradually decreases, and suddenly increases at the intersection with the feeding area 441.

[0063] A guide hook structure is installed on the four side walls of the furnace body. The guide hook structure and the hook component 12 are compatible.

[0064] The opening and closing structure includes two opening and closing plates 5 with opposite directions of movement. The opening and closing plates 5 are used to seal the bottom of the furnace body 4.

[0065] like Figure 1 As shown, the opening / closing plate 5 includes:

[0066] Door panel 511, with guide plates 53 on both sides of door panel 511, the guide plates 53 are used to restrict the direction of opening and closing the bottom opening of the furnace body 4 of door panel 511;

[0067] A driver 510 is provided, and a slide plate 512 is mounted on the output end of the driver 510. The slide plate 512 moves horizontally.

[0068] The lifting rod 59 has hinged ends, which are connected to the slide plate 512 and the door panel 511 respectively.

[0069] The actuator 510 drives the sliding plates 512 to move horizontally closer together. Simultaneously, the lifting rod 59 drives the door panels 511 upwards, causing them to move closer together. When the sides of the door panels 511 contact each other, they rise together to block the opening. When the door is opened, the actuator 510 continues to drive the sliding plates 512 closer together, and the door panels 511 continue to rise. Then, the actuator 510 drives the sliding plates 512 to move horizontally away from each other. The door panels 511 first move downwards to open the oven opening and then move to the sides.

[0070] like Figure 1 As shown, a flexible load-bearing structure is installed inside the water-cooled box 3. The flexible load-bearing structure includes spring damping columns 32 and a load-bearing plate 31. The load-bearing plate 31 is installed inside the water-cooled box 3 via the spring damping columns 32. The load-bearing plate 31 has upward-facing through holes evenly distributed on it. During the damping process, the low-temperature water at the bottom is rapidly circulated upward to form convection, thereby accelerating the cooling efficiency and ensuring the structural integrity.

[0071] The feeding mechanism 2 lifts the rack 1 containing the aluminum products of the compressor from the bottom opening of the furnace body 4 into the furnace. The guide post 121 on the hook 12 on the side of the rack 1 moves upward through the groove 43 into the feeding area 441 of the hook area 44 and then into the hook area 442 to complete the hooking. During the feeding process, the end of the circulating fan shaft 42 and the spline joint 115 on the guide structure 113 are fitted and installed, and the sealing plate 112 opens the circulation hole 111. After the feeding mechanism 2 completes the feeding, it is removed from the bottom opening. The opening and closing plate 5 of the opening and closing structure seals the bottom opening of the furnace body 4. The heating structure begins operation, with the drive motor 41 rotating the circulating fan shaft 42. Airflow circulates between the inner and outer temperature zones of the steam overflow hood 11. When the temperature reaches 500±50℃, heat preservation is performed. After heat preservation, the opening / closing door 5 lifts the material rack 1 upwards. The movable pin 123 enters the unloading area 443 from the hook area 442. Then, the bottom opening of the furnace body 4 is opened. The opening / closing door 5 first descends and then opens the furnace bottom to both sides. The material rack 1, having lost its support, instantly falls into the water-cooled tank 3. Upon entering the water-cooled tank 2, it presses down on the support tray 31. The support tray 31, via the spring damping column 32, reduces the impact of the material rack 1 on the water tank 3. During the descent of the material rack 1, the circulating fan shaft 42 separates from the spline joint 115, and the sealing plate 112, under the action of the elastic column 114, seals the circulation hole 111. Simultaneously, the elastic column 114 can be a magnetic telescopic column to accelerate the reset efficiency and reduce the reset time.

[0072] A solution treatment method for an aluminum scroll disk, comprising the following steps:

[0073] Feeding:

[0074] The material rack 1, which carries the aluminum vortex disc workpiece, is carried by the feeding mechanism 2 and moved to the bottom of the furnace body 4. The feeding mechanism 2 is a lifting platform. The movable pin 123 enters the groove 43 and enters the top feeding area 441 along the groove 43, and finally enters the hook area 442. During the feeding process, the end of the circulating fan shaft 42 enters the spline joint 115 to complete the fit. Then the flow guide structure 113 is pressed down and the sealing plate 112 opens the circulation hole 111.

[0075] Solution treatment:

[0076] The driver 510 drives the door panel 511 to approach each other between the two guide plates 53 via the lifting rod 59. When the two door panels 511 contact each other, the two door panels 511 move upward together to block the bottom opening of the furnace body 4. The heating structure inside the furnace body 4 starts to work. The drive motor 41 drives the circulating fan shaft 42 and the fan blade to rotate. After the temperature inside the furnace rises to 500±50℃, it is heat preservation treatment.

[0077] cool down:

[0078] The drive unit 510 drives the door panel 511 to continue to move closer to each other between the two guide plates 53 via the lifting rod 59, pushing the material rack 1. The movable pin 123 of the hook body on the side of the material rack 1 enters the top of the unloading area 443 from the hook area 442. The bottom of the material rack 1 is supported on the door panel 511. The movable pin 123 enters the unloading area 443 from the hook area 442 and then moves down along the unloading area 443.

[0079] The driver 511 drives the two door panels 511 and the material rack 1 to descend rapidly via the lifting rod 59. The two door panels 511 will move downward first and then to the sides, opening the bottom opening of the furnace body 4. When the door panels 511 are completely separated from the material rack 1, the material rack 1 will fall instantly into the water cooling box 3. The impact on the water cooling box 3 is reduced by the bearing plate 31 and the spring shock absorber 32. The bearing plate 31 is provided with through holes, and the through holes on the bearing plate 31 will allow the low temperature water to flow upward. During the descent, the bottom of the circulating fan shaft 42 is separated from the bottom of the guide structure 113. The sealing plate 112 seals the circulation hole 111 via the elastic column 114, and the material rack 1 and the workpiece on it are cooled to below 100°C.

[0080] Example 2 uses a different structure for the opening and closing plate than in Example 1, specifically including:

[0083] Sub-plate 54 is installed between two ear plates 52. An elastic body 55 is provided between the sub-plate 54 and the main plate 51. A guide body 541 is provided on the side of the sub-plate 54. The guide body 541 is adapted to the guide structure for installation.

[0084] The support plate 56 is located diagonally below the main board 51 and is used to slide and support the main board 51. The support plate 56 is fixed on the opposite side of the guide plate 53.

[0085] Drive rod 57, drive rod 57 is located below sub-plate 54;

[0086] Driven rod assembly 58 has hinged ends, which are connected to sub-plate 54 and drive rod 57 respectively.

[0087] The guide structure includes a lifting section 521 and a vertical section 522. The lifting section 521 is used for the oblique guide plate 54, and the vertical section 522 is adapted to the vertical guide plate 54. A ramp structure is provided at the bottom of the opposite side of the two plates 54. The inclination angle of the ramp structure is greater than the inclination angle of the lifting section 521.

[0088] The bottom of the steam overflow cover 11 is provided with a ramp structure. The ramp structure is suitable for squeezing the main plate 51 when falling, so that it moves outward relative to the sub-plate 54 and exposes the sub-plate 54 on the horizontal surface so as to support the material rack 1.

[0089] A solution treatment method for an aluminum scroll disk, comprising the following steps:

[0090] Feeding:

[0091] The material rack 1, which carries the aluminum vortex disc workpiece, is carried by the feeding mechanism 2 and moved to the bottom of the furnace body 4. The feeding mechanism 2 is a lifting platform. The movable pin 123 enters the groove 43 and enters the top feeding area 441 along the groove 43, and finally enters the hook area 442. During the feeding process, the end of the circulating fan shaft 42 enters the spline joint 115 to complete the fit. Then the flow guide structure 113 is pressed down and the sealing plate 112 opens the circulation hole 111.

[0092] Solution treatment:

[0093] Drive rod 57 drives main plate 51 to approach each other between two guide plates 53 via driven rod. When the two main plates 51 contact each other, secondary plate 54 approaches each other along lifting section 521 and pulls elastic body 55. Finally, vertical section 522 vertically flattens the space between the two main plates 51 and moves upward together with main plate 51 to seal the bottom opening of furnace body 4. Heating structure inside furnace body 4 starts to work. Drive motor 41 drives circulating fan shaft 42 and fan blade to rotate. After the temperature inside the furnace rises to 500±50℃, heat preservation treatment is performed.

[0094] cool down:

[0095] Drive rod 57 drives two sub-plates 54 and main plate 51 to continue moving upward via driven rod group 58, pushing material rack 1. The movable pin 123 of the hook body on the side of material rack 1 enters the top of the unloading area 443 from the hook area 442. The bottom of material rack 1 is supported on sub-plates 54 and main plate 51. The movable pin 123 enters the unloading area 443 from the hook area 442 and moves downward along the unloading area 443.

[0096] Drive rod 57, via driven rod assembly 58, drives two auxiliary plates 54, two main plates 51, and material rack 1 to descend rapidly. Main plates 51 and auxiliary plates 54 first move downwards, then to the sides, opening the opening at the bottom of furnace body 4. After main plates 51 descend onto support plate 56, they move to the sides. After opening the bottom opening, main plates 51 detach from the bottom of material rack 1. Under the action of elastic body 55, main plates 51 rise relative to auxiliary plates 54 and press their sides against the sides of material rack 1. Subsequently, auxiliary plates 54 support material rack 1 as it descends. As auxiliary plates 54 continue downwards, they move to the sides together with main plates 51, while the compression of elastic body 55 is gradually released. When auxiliary plates 54 are completely detached from material rack 1, the material rack... The rack 1 will instantly fall into the water-cooled box 3, while the steam overflow cover 11 will be supported on the sub-plate 54. The bottom of the circulating fan shaft 42 will detach from the bottom of the guide structure 113. The sealing plate 112 will seal the circulation hole 111 through the elastic column 114. When the steam overflow cover 11 is supported on the sub-plate 54, the main plate 51 will be pressed and fixed on the side of the steam overflow cover 11 by the slope structure under the action of the elastic body 55. The rack 1 and the workpiece on it will be cooled to below 100°C in the water-cooled box 3. The drive rod 57 will continue to drive the two sub-plates 54 away from each other through the driven rod group 58 until the steam overflow cover 11 is completely separated from the sub-plate 54. The rack 4 will fall onto the bearing plate 31 and the impact force will be reduced by the spring damping column 32.
