Description

Technical Field

[0001] This invention relates to the field of heat treatment processing technology for aluminum alloy wheel hubs, specifically a multi-layer aluminum alloy solution aging production line. Background Technology

[0002] Currently, the performance requirements for high-strength aluminum alloy components in aerospace, rail transportation, and other fields are constantly increasing. When mass-producing lightweight, high-strength components such as aluminum alloy wheels, a complete set of heat treatment processes—solution, quenching, and aging—is typically required to be completed continuously. The treatment effect directly determines the quality of the finished component. The solution furnace is the core equipment for heat treatment of metal materials, mainly used for solution strengthening of metal workpieces such as aluminum alloys and stainless steel. Through high-temperature heating, solute atoms inside the workpiece are fully dissolved into the matrix. Combined with quenching and aging treatments, grain boundary control and uniform precipitation of the second phase are achieved, ultimately improving the strength, toughness, and corrosion resistance of the aluminum alloy components. Currently, most mainstream aluminum alloy solution aging production lines on the market are single-layer horizontal or single-layer vertical structures, primarily using intermittent, single-channel assembly line production modes.

[0003] In existing technologies, the solution treatment, quenching, and aging processes in the heat treatment of aluminum alloy wheels have large gaps between them. Moreover, they are mostly manually assisted in loading and unloading and transferring materials, resulting in high labor intensity and labor costs. This can easily lead to problems such as workpiece collisions, excessive transfer time, and delayed process connections. Consequently, the quenching transfer time is uncontrollable, and the workpiece temperature drops rapidly during the transfer process, making it difficult to ensure the stability of the heat treatment process. This results in poor uniformity of the mechanical properties of the finished aluminum alloy wheels. Furthermore, the production line equipment occupies a large area, resulting in low space utilization of the production line. The vertical space of the factory building has not been effectively developed, and capacity expansion cannot be achieved within the limited factory space, making it impossible to meet the continuous production needs of large-volume aluminum alloy wheels. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-layer aluminum alloy solution treatment and aging production line. This solves the problems of large gaps between the solution treatment, quenching, and aging processes in the heat treatment of aluminum alloy wheels, which often rely on manual loading and unloading and process transfer. This results in high labor intensity and costs, easily leading to workpiece collisions, excessive transfer time, and delayed process connections. Furthermore, it causes uncontrollable quenching transfer time, rapid temperature loss during transfer, and difficulty in ensuring the stability of the heat treatment process, resulting in poor uniformity of the mechanical properties of the finished aluminum alloy wheels. Additionally, the production line occupies a large area, has low space utilization, and fails to effectively utilize vertical space within the factory, making it impossible to expand production capacity within limited factory space and meet the continuous production needs of large-volume aluminum alloy wheels.

[0014] This invention provides a multi-layer aluminum alloy solution treatment and aging production line. It offers the following advantages: This multi-layer aluminum alloy solution treatment and aging production line, through the coordination of a solution furnace, an aging furnace, multi-layer conveyor rollers, feeding and discharging components, loading and unloading components, material transfer components, and a quenching tank, arranges the solution furnace and aging furnace vertically, making full use of the factory's vertical space and reducing the floor space occupied by the production line equipment. Simultaneously, through multi-layer continuous conveying channels and fully automated feeding, unloading, loading, unloading, and process transfer connections, it enables continuous batch processing of aluminum alloy wheels from solution treatment, quenching treatment to aging treatment, thus improving the production efficiency of aluminum alloy wheel heat treatment, reducing manual labor intensity and labor costs, and avoiding workpiece collisions and time-consuming transfers caused by manual handling. It significantly shortens the interval between solution treatment completion and quenching start, ensuring the stability of heat treatment process parameters, thereby improving the uniformity of the mechanical properties of the finished aluminum alloy wheels. This meets the needs of continuous production of large quantities of aluminum alloy wheels.

[0015] By coordinating the fixed frame, the third conveyor roller, the purge pipe, the air supply pipe, the solenoid valve, and the inductive proximity sensor, the residual quenching liquid on the surface of the aluminum alloy wheel hub is purged and removed during the conveying process before the aluminum alloy wheel hub is sent into the aging furnace after quenching. This prevents the quenching liquid from being carried into the aging furnace with the workpiece, thus avoiding affecting the heat treatment environment inside the aging furnace. At the same time, it can also prevent the residual quenching liquid from evaporating rapidly at high temperatures, causing corrosion and discoloration on the workpiece surface, thereby ensuring the appearance quality of the finished workpiece.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0019] In existing technologies, the solution treatment, quenching, and aging processes in the heat treatment of aluminum alloy wheels have large gaps between them. Moreover, they are mostly manually assisted in loading and unloading and transferring materials, resulting in high labor intensity and labor costs. This can easily lead to problems such as workpiece collisions, excessive transfer time, and delayed process connections. Consequently, the quenching transfer time is uncontrollable, and the workpiece temperature drops rapidly during the transfer process, making it difficult to ensure the stability of the heat treatment process. This results in poor uniformity of the mechanical properties of the finished aluminum alloy wheels. Furthermore, the production line equipment occupies a large area, resulting in low space utilization of the production line. The vertical space of the factory building has not been effectively developed, and capacity expansion cannot be achieved within the limited factory space, making it impossible to meet the continuous production needs of large-volume aluminum alloy wheels.

[0020] In view of this, the present invention provides a multi-layer aluminum alloy solution treatment and aging production line. Through the coordination of a solution furnace, an aging furnace, multi-layer conveyor rollers, feeding and discharging components, loading and unloading components, material transfer components, and a quenching tank, the solution furnace and aging furnace are arranged vertically, making full use of the vertical space of the factory and reducing the floor space occupied by the production line equipment. Simultaneously, through multi-layer continuous conveying channels and fully automated feeding, unloading, loading, unloading, and process transfer connections, the entire process of aluminum alloy wheel hubs from solution treatment, quenching treatment to aging treatment is automated and continuously processed in batches. This improves the production efficiency of aluminum alloy wheel hub heat treatment, reduces manual labor intensity and labor costs, and avoids workpiece collisions and time-consuming transfers caused by manual handling. It significantly shortens the interval between solution treatment completion and quenching start, reduces workpiece temperature loss, ensures the stability of heat treatment process parameters, and thus improves the uniformity of the mechanical properties of the finished aluminum alloy wheel hubs, meeting the needs of continuous production of large batches of aluminum alloy wheel hubs.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Depend on Figure 1-8As can be seen, a multi-layer aluminum alloy solution treatment and aging production line includes a solution furnace 1, an aging furnace 2 above the solution furnace 1, and multiple layers of conveying rollers 3 inside both the solution furnace 1 and the aging furnace 2. A quenching tank 8 is located below one end of the solution furnace 1. The multi-layer aluminum alloy solution treatment and aging production line also includes a feeding and discharging assembly 4, a loading and unloading assembly 5, and a material transfer assembly 6. The feeding and discharging assembly 4 is located at both ends of the solution furnace 1 and the aging furnace 2. The loading and unloading assembly 5 is located at the end of the solution furnace 1 and the aging furnace 2 away from the quenching tank 8. The material transfer assembly 6 is located at the end of the solution furnace 1 near the quenching tank 8. The feeding and discharging assembly 4 adopts a multi-layer conveying structure to feed or discharge materials into the solution furnace 1 and the aging furnace 2. The loading and unloading assembly 5 performs loading and unloading operations to the feeding and discharging assembly 4 at the loading end and the unloading end through a lifting conveying structure. The material transfer assembly 6 transports the materials that have completed the solution treatment in batches to the quenching process, and after the quenching operation is completed, it is transported to the aging furnace 2. In the specific implementation process, it is worth noting that the solution treatment furnace 1 and the aging furnace 2 are existing mature heat treatment furnace structures, arranged vertically to make full use of the vertical space of the factory. Compared with the traditional flat layout, this significantly reduces the floor space of the production line. Furthermore, the multi-layered conveyor rollers 3 form multi-layered conveying channels, effectively increasing the processing capacity of the production line and meeting the continuous production needs of large-volume aluminum alloy wheel hubs. The quenching tank 8 is used to quickly quench and cool the aluminum alloy wheel hubs after solution treatment, ensuring that the heat treatment process meets the requirements. As required, the feeding and discharging assembly 4 is used to receive and transport materials at the feeding and discharging ends of the solution furnace 1 and the aging furnace 2, and can complete the feeding or discharging operation of aluminum alloy wheel hubs into the multi-layer conveying channel in batches. The loading and unloading assembly 5 uses a lifting conveying structure to transport multiple aluminum alloy wheel hubs to be processed layer by layer to the feeding and discharging assembly 4 located at the feeding end of the solution furnace 1, or to receive aluminum alloy wheel hubs that have completed solution and aging treatment layer by layer. The material transfer assembly 6 receives the materials conveyed by the feeding and discharging assembly 4 in batches at the discharging end of the solution furnace 1, and transfers the materials to the material transfer assembly 6. The material is immersed in the quenching tank 8 to complete the quenching operation, and then transferred as a whole to the feeding and discharging assembly 4 at the feeding end of the aging furnace 2. The quenched aluminum alloy wheel hub is then sent into the aging furnace 2 for aging treatment. Through the cooperation between the solution furnace 1, aging furnace 2, multi-layer conveyor rollers 3, feeding and discharging assembly 4, loading and unloading assembly 5, material transfer assembly 6, and quenching tank 8, the solution furnace 1 and aging furnace 2 are arranged vertically, making full use of the vertical space of the factory and reducing the floor space occupied by the production line equipment. At the same time, through multi-layer continuous conveying channels and fully automated feeding and unloading, the material is effectively utilized. By seamlessly integrating with intermediate processes, this system enables fully automated, continuous batch operations of aluminum alloy wheels, from solution treatment and quenching to aging treatment. This improves the production efficiency of heat treatment processing of aluminum alloy wheels, reduces manual labor intensity and costs, and avoids issues such as workpiece collisions and excessive transfer time caused by manual handling. It also significantly shortens the interval between solution treatment completion and quenching start, reduces workpiece temperature loss, and ensures the stability of heat treatment process parameters. Consequently, it enhances the uniformity of the mechanical properties of finished aluminum alloy wheels, meeting the needs of continuous production of large quantities of aluminum alloy wheels.

[0023] Furthermore, the feeding / discharging assembly 4 includes a base 41, a movable frame 42, first conveying rollers 43, first through-beam photoelectric sensors 44, and a translation drive assembly 45. Multiple bases 41 are provided, distributed at both ends of the solution furnace 1 and the aging furnace 2. The movable frame 42 is movably connected to the top of the base 41. Multiple sets of first conveying rollers 43 are provided, equidistantly arranged inside the movable frame 42, and correspondingly arranged on the multi-layer conveying rollers 3. Multiple sets of first through-beam photoelectric sensors 44 are provided, installed on both sides of the movable frame 42, and correspondingly arranged on the first conveying rollers 43. The translation drive assembly 45 is located at the bottom of the movable frame 42. The movable frame 42 moves horizontally on the top of the base 41 via the translation drive assembly 45, aligning each layer of first conveying rollers 43 with the corresponding height of the multi-layer conveying rollers 3. The rotation of the first conveying rollers 43 completes the feeding or discharging operation of materials at the corresponding layer level. The first through-beam photoelectric sensors 44 are used to detect the material's arrival status. In the specific implementation process, it is worth noting that through the cooperation between the base 41, the moving frame 42, the first conveying roller 43, the first through-beam photoelectric sensor 44, and the translation drive assembly 45, the first conveying roller 43 on the moving frame 42 is arranged in multiple layers and corresponds to the multi-layer conveying roller 3. Each layer of the first conveying roller 43 is driven by an independent motor. The translation drive assembly 45 drives the moving frame 42 to move horizontally on the top of the base 41, aligning the first conveying roller 43 of each layer with the multi-layer conveying roller 3 at the inlet and outlet of the solution furnace 1 or aging furnace 2. This enables the batch feeding or receiving of aluminum alloy wheel hubs into the solution furnace 1 or aging furnace 2, and the material is moved to the side away from the solution furnace 1 or aging furnace 2 for loading or unloading. The first through-beam photoelectric sensor 44 is used to detect the material position on the first conveying roller 43 and monitor the material receiving or unloading process to ensure the automated control of the feeding and discharging process. The specific model of the first through-beam photoelectric sensor 44 is not limited, as long as it meets the usage requirements.

[0024] Furthermore, the translation drive assembly 45 includes a moving rail 451, moving wheels 452, a ball screw 453, a first servo motor 454, and a laser rangefinder 455. Two moving rails 451 are provided, located on the top sides of the base 41; two sets of moving wheels 452 are provided, rotatably connected to the bottom of the moving frame 42 and mating with the inner wall of the moving rail 451; the ball screw 453 is rotatably connected to the top of the base 41 and threadedly connected to the bottom of the moving frame 42; the first servo motor 454... 4 is fixedly connected to the top of the base 41 at one end of the ball screw 453, and the output end is connected to the ball screw 453 for transmission; the laser range sensor 455 is fixedly connected to one side of the top of the base 41 and is correspondingly set on the side of the moving frame 42; wherein, the first servo motor 454 drives the ball screw 453 to rotate, drives the moving frame 42 to move horizontally along the moving rail 451, and detects the position of the moving frame 42 in real time through the laser range sensor 455, and accurately controls the stopping position of the moving frame 42; In the specific implementation process, it is worth noting that through the cooperation between the base 41, the movable frame 42, the movable rail 451, the movable wheel 452, the ball screw 453, the first servo motor 454, and the laser rangefinder 455, the first servo motor 454 is controlled to drive the ball screw 453 to rotate, thereby driving the movable frame 42 to move horizontally along the movable rail 451. The position of the movable frame 42 is fed back in real time by the laser rangefinder 455, and the stopping position of the movable frame 42 is controlled, thereby ensuring the stable and smooth material feeding and conveying process and avoiding misalignment and jamming problems. The specific models of the first servo motor 454 and the laser rangefinder 455 are not limited, as long as they meet the usage requirements.

[0025] Furthermore, the loading and unloading assembly 5 includes a vertical seat 51, a first lifting seat 52, a chain conveyor 53, and a first lifting drive assembly 54. Two vertical seats 51 are provided, distributed on the side of the solution furnace 1 and the aging furnace 2 away from the quenching tank 8, and located on the side of the moving frame 42 away from the solution furnace 1 and the aging furnace 2. The first lifting seat 52 is provided on the side of the vertical seat 51 close to the moving frame 42. The chain conveyor 53 is fixedly connected to the top of the first lifting seat 52. The first lifting drive assembly 54 is provided inside the vertical seat 51. The first lifting seat 52 drives the chain conveyor 53 to move up and down on the vertical seat 51 through the first lifting drive assembly 54, so that the chain conveyor 53 can move to the corresponding height and align with the first conveyor roller 43 of the corresponding layer, and cooperate with the first conveyor roller 43 to complete the loading and unloading operation of materials. In the specific implementation process, it is worth noting that the first lifting seat 52 moves up and down on the vertical seat 51 by the drive of the first lifting drive component 54, thereby driving the chain conveyor 53 to align with the first conveyor rollers 43 of each layer of the moving frame 42 located at the loading and unloading end, thereby loading multiple aluminum alloy wheel hubs to be processed onto the moving frame 42 located at the loading end of the solution furnace 1 layer by layer, or receiving the processed aluminum alloy wheel hubs layer by layer from the moving frame 42 located at the unloading end of the aging furnace 2, thus realizing automated loading and unloading operations.

[0026] Furthermore, the first lifting drive assembly 54 includes a slide rail 541, a second servo motor 542, a first chain 543, and a second through-beam photoelectric sensor 544. Multiple slide rails 541 are fixedly connected to the inner wall of the vertical seat 51 and slidably connected to the first lifting seat 52. The second servo motor 542 is fixedly connected to the top of the vertical seat 51. The first chain 543 is located on both sides of the vertical seat 51, fixedly connected to the outer wall of the first lifting seat 52, and driven by the output end of the second servo motor 542. Multiple sets of second through-beam photoelectric sensors 544 are equidistantly fixedly connected to the vertical seat 51 and correspondingly located on the first lifting seat 52. The second servo motor 542 drives the first chain 543 to rotate, thereby causing the first lifting seat 52 to move up and down along the slide rail 541. The second through-beam photoelectric sensor 544 detects the position of the first lifting seat 52, ensuring that the chain conveyor 53 is aligned with the first conveyor roller 43 at the corresponding height of the feeding / discharging assembly 4. In the specific implementation process, it is worth noting that the rotation of the second servo motor 542 drives the first chain 543 to operate, pulling the first lifting seat 52 to move up and down along the slide rail 541. The second through-beam photoelectric sensor 544 detects the arrival signal of the first lifting seat 52 and controls the stop position of the first lifting seat 52 to ensure that the chain conveyor 53 can be accurately aligned with the first conveyor rollers 43 of each layer, avoiding material conveying jams and collisions due to misalignment, and ensuring the accuracy and stability of loading and unloading operations. The specific models of the second servo motor 542 and the second through-beam photoelectric sensor 544 are not limited, as long as they meet the usage requirements.

[0027] Furthermore, the material transfer assembly 6 includes a vertical frame 61, a second lifting seat 62, a second conveying roller 63, and a second lifting drive assembly 64. The vertical frame 61 is disposed inside the quenching tank 8, and its top extends to one side of the aging furnace 2. The second lifting seat 62 is movably connected to the inside of the vertical frame 61. Multiple sets of the second conveying roller 63 are disposed at equal intervals inside the second lifting seat 62 and correspondingly disposed to the first conveying roller 43. The second lifting drive assembly 64 is disposed on the top of the vertical frame 61. The vertical frame 61 moves up and down inside the vertical frame 61 through the second lifting drive assembly 64, so that the second conveying roller 63 can sequentially align with the first conveying roller 43 at the discharge end of the solution furnace 1, the quenching surface of the quenching tank 8, and the first conveying roller 43 at the feed end of the aging furnace 2, sequentially receiving the material that has completed the solution treatment, immersing and quenching the material, and conveying the quenched material to the aging furnace 2. In the specific implementation process, it is worth noting that the second lifting seat 62 moves up and down inside the vertical frame 61 under the drive of the second lifting drive assembly 64. After the second conveyor rollers 63 of each layer are aligned with the first conveyor rollers 43 of each layer located at the discharge end of the solution furnace 1, they receive the aluminum alloy hubs that have completed the solution treatment in batches. Then, the second lifting seat 62 descends as a whole, immersing the second conveyor rollers 63 and the aluminum alloy hubs they carry into the quenching medium in the quenching tank 8 to quickly complete the quenching operation. After the quenching is completed, the second lifting seat 62 rises as a whole until the second conveyor rollers 63 of each layer are aligned with the first conveyor rollers 43 of each layer located at the feed end of the aging furnace 2. Then, the quenched aluminum alloy hubs are transported to the next process, shortening the interval time from solution treatment to quenching, reducing the temperature loss of the workpiece, and ensuring the heat treatment process effect.

[0028] Furthermore, the second lifting drive assembly 64 includes a vertical rail 641, rollers 642, an electric winch 643, and a wire rope 644. Two sets of vertical rails 641 are fixedly connected to both sides of the vertical frame 61. Two sets of rollers 642 are rotatably connected to both sides of the second lifting seat 62 and are also connected to the inner wall of the vertical rail 641. The electric winch 643 is fixedly connected to the top of the vertical frame 61. One end of the wire rope 644 is fixedly connected to the top of the second lifting seat 62, and the other end is wound around the output end of the electric winch 643. The electric winch 643, by winding and unwinding the wire rope 644, drives the second lifting seat 62 to move up and down along the vertical rail 641, causing the second conveyor roller 63 to precisely stop at a preset position, completing the material receiving, quenching transfer, and intermediate loading operations. In the specific implementation process, it is worth noting that the electric winch 643 winds up and unwinds the wire rope 644, and the roller 642 guides the second lifting seat 62 along the vertical rail 641 to realize the lifting and moving of the second lifting seat 62, ensuring smooth connection between the processes of solution discharge, overall quenching, and aging feeding. The specific model of the electric winch 643 is not limited, as long as it meets the usage requirements.

[0029] Furthermore, a blowing assembly 7 is provided on the side of the vertical frame 61 near the aging furnace 2. The blowing assembly 7 includes a fixed frame 71, a third conveyor roller 72, a purge pipe 73, an air supply pipe 74, a solenoid valve 75, and an inductive proximity sensor 76. The fixed frame 71 is located on the side of the vertical frame 61 near the aging furnace 2 and on the side of the movable frame 42 away from the aging furnace 2. Multiple sets of the third conveyor roller 72 are provided, equidistantly arranged inside the fixed frame 71, and correspondingly arranged on the first conveyor roller 43 and the second conveyor roller 63. Multiple sets of purge pipes 73 are provided, equidistantly fixedly connected to the inner side of the fixed frame 71 located on the third conveyor roller 72. Above 2; the air supply pipe 74 is fixedly connected to the bottom inner side of the fixing frame 71; multiple solenoid valves 75 are provided, equidistantly connected to the top of the air supply pipe 74, and the output end is connected to the purge pipe 73; multiple inductive proximity sensors 76 are provided, equidistantly fixedly connected to one side of the fixing frame 71; wherein, the material that has completed the quenching operation is conveyed to the third conveyor roller 72 by the second conveyor roller 63. When the inductive proximity sensor 76 detects that the material has arrived, the solenoid valve 75 at the corresponding position opens, and the high-pressure gas in the air supply pipe 74 is sprayed downward through the purge pipe 73 to purge and remove the residual quenching liquid carried on the surface of the material; In the specific implementation process, it is worth noting that after the aluminum alloy wheel hub is quenched, it is conveyed from the second conveyor roller 63 to the third conveyor roller 72. When the inductive proximity sensor 76 detects that the material has arrived, it triggers the opening of the corresponding solenoid valve 75. High-pressure gas is introduced into the purge pipe 73 from the gas supply pipe 74 and sprayed downwards from the nozzle of the purge pipe 73 onto the surface of the aluminum alloy wheel hub. This purges and removes the excess quenching liquid adhering to the surface of the wheel hub, preventing the quenching liquid from being carried into the aging furnace 2 and preventing residual quenching liquid from affecting the process stability of subsequent aging treatment. The inductive proximity sensor 76 can accurately identify the material in place and only opens the corresponding purge passage when material passes by, reducing unnecessary gas consumption and reducing production energy consumption. The specific models of the solenoid valve 75 and the inductive proximity sensor 76 are not limited, as long as they meet the usage requirements.

[0030] Furthermore, a circulation pipe 81 is equidistantly connected to one side of the interior of the quenching tank 8, and a temperature control component 82 is fixedly connected to one side of the inner wall of the quenching tank 8. In the specific implementation process, it is worth noting that the circulation pipe 81 is used to circulate and transport the quenching medium in the quenching tank 8, and works with the temperature control component 82 to adjust the temperature of the quenching medium in real time, so as to ensure the temperature of the quenching medium is stable during the quenching process, avoid the quenching cooling effect being reduced due to temperature rise, and ensure the quenching quality of the aluminum alloy wheel hub is stable.

[0031] The working principle of this application is illustrated below with a preferred embodiment: 1. The robotic arm located at the feeding end places the aluminum alloy wheel hub to be heat-treated on the top of the chain conveyor 53. The second servo motor 542 drives the first lifting seat 52 to rise and fall according to the preset command, so that the chain conveyor 53 is aligned with the first conveyor roller 43 of the corresponding layer at the feeding end of the solution furnace 1. The aluminum alloy wheel hub is conveyed to the first conveyor roller 43, and the first conveyor roller 43 of each layer at the feeding end of the solution furnace 1 is filled with aluminum alloy wheel hubs. 2. When it is necessary to feed material into the solution furnace 1, open the furnace door at the feeding end of the solution furnace 1 and control the first servo motor 454 located at the feeding end of the solution furnace 1 to drive the moving frame 42 to move towards the solution furnace 1, so that the first conveying rollers 43 of each layer are aligned with the multi-layer conveying rollers 3 inside the solution furnace 1. The first conveying rollers 43 rotate to send the aluminum alloy wheel into the solution furnace 1. Through the rotation of the multi-layer conveying rollers 3, the aluminum alloy wheel is conveyed inside the solution furnace 1 and undergoes solution treatment during the conveying process. When the aluminum alloy wheel moves to the discharge end of the solution furnace 1, open the furnace door at the discharge end of the solution furnace 1 and convey the aluminum alloy wheel that has completed the solution treatment onto the first conveying roller 43 of the moving frame 42 at the discharge end. 3. Then, control the first servo motor 454 located at the discharge end of the solution furnace 1 to move the moving frame 42 towards the vertical frame 61, align the first conveyor rollers 43 carrying aluminum alloy hubs on each layer with the second conveyor rollers 63 at the corresponding height on the material transfer assembly 6, and transport the aluminum alloy hubs to the second conveyor rollers 63 on the second lifting seat 62. The electric winch 643 releases the wire rope 644, driving the second lifting seat 62 to descend as a whole, and immersing the second conveyor rollers 63 and the aluminum alloy hubs completely into the quenching medium in the quenching tank 8. After the preset quenching time is completed, the electric winch 643 winds up the wire rope 644 to lift the second lifting seat 62 as a whole until the second conveyor rollers 63 on each layer are aligned with the third conveyor roller 72, and transport the aluminum alloy hubs to the third conveyor roller 72. After the inductive proximity sensor 76 detects that the aluminum alloy hubs are in place, it opens the solenoid valve 75 at the corresponding position, and high-pressure gas is sprayed out through the purge pipe 73 to purge and remove the excess quenching liquid adhering to the surface of the hubs. 4. The third conveyor roller 72 conveys the cleaned aluminum alloy wheel hub to the first conveyor roller 43 located on the moving frame 42 at the feed end of the aging furnace 2. The first servo motor 454 drives the moving frame 42 to move towards the aging furnace 2. At the same time, the furnace door at the feed end of the aging furnace 2 is opened, and the cleaned aluminum alloy wheel hub is conveyed to the top of the multi-layer conveyor roller 3. It is conveyed in the aging furnace 2 through the multi-layer conveyor roller 3 and the aging treatment is completed during the conveying process. 5. After the aging treatment is completed, the aluminum alloy wheel hub is conveyed to the discharge end of the aging furnace 2. The furnace door of the discharge end of the aging furnace 2 is opened, and the heat-treated aluminum alloy wheel hub is conveyed to the first conveyor roller 43 located on the moving frame 42 at the discharge end of the aging furnace 2. The first servo motor 454 drives the moving frame 42 to move closer to the vertical seat 51. The chain conveyor 53 receives and unloads the heat-treated aluminum alloy wheel hub layer by layer, and the robotic arm located at the unloading end removes the heat-treated aluminum alloy wheel hub from the production line. Repeating the above process can realize multi-layer continuous aluminum alloy solution aging processing production.
