Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, specifically to an aluminum alloy solution heat treatment apparatus and its usage method. Background Technology

[0002] After casting or machining, the alloying elements in aluminum alloys are often unevenly distributed, which may form an unbalanced structure or coarse precipitates, leading to unstable material properties. Solution heat treatment, by heating the aluminum alloy to a specific temperature and holding it for a certain time, allows these alloying elements to dissolve into the aluminum matrix to the maximum extent, forming a uniform supersaturated solid solution.

[0003] A solution heat treatment furnace and solution treatment method for aluminum alloy processing, disclosed in CN113736975B, relates to the field of aluminum alloy processing technology. The furnace includes a solution heat treatment furnace with a pusher slot on the left side. A pusher plate is slidably connected inside the pusher slot. The left side of the pusher plate is connected to the output end of a hydraulic push rod. A discharge pipe is connected between the solution heat treatment furnace and a cooling mechanism. A closing plate is rotatably connected to the top of the discharge pipe via a hinge.

[0004] A pusher-type aluminum alloy solution aging heat treatment production line, disclosed in CN203878194U, includes a control system, a feeding device, a pusher-type solution furnace, a high-pressure air quenching chamber, a pusher-type aging furnace, an air cooling platform, and a unloading platform. This utility model's pusher-type aluminum alloy solution aging heat treatment production line uses a high-pressure air quenching chamber for high-pressure air cooling of aluminum alloy parts, resulting in rapid cooling.

[0005] In existing technologies, a significant amount of manual assistance is required to transfer the material frame between different processing stages, such as feeding, solution treatment, cooling, and aging, which limits production efficiency. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to provide an aluminum alloy processing solution heat treatment apparatus and its usage method in order to solve the above-mentioned problems.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The present invention provides an aluminum alloy processing solution heat treatment device, including a base and a support frame provided on the base. A solution furnace is provided on the upper side of the support frame, a cooling water tank is provided on the lower side of the support frame, and a first conveyor for unloading and a second conveyor for loading are respectively provided on both sides of the support frame.

[0011] The support frame is equipped with a station conversion component for changing the position of the material frame at each station of the solution furnace, the first conveyor, the cooling water tank and the second conveyor.

[0012] A material support structure for supporting the material frame and adjusting its height is provided between the first conveyor and the station conversion component, and between the second conveyor and the station conversion component. An aging furnace for heating the material frame conveyed on the first conveyor is provided at the location of the first conveyor.

[0013] The second conveyor is provided with a push rod drive structure for pushing the material frame from the second conveyor to the corresponding material support structure and for pushing the material frame from the corresponding material support structure to the first conveyor.

[0014] Furthermore, the workstation conversion assembly includes two parallel rotating rods. The middle part of the rotating rods is rotatably connected to the support frame via a rotating shaft. Both ends of the rotating rods are rotatably connected to fixed blocks. Each fixed block is fixedly equipped with a hydraulic cylinder. The push rod head of the hydraulic cylinder is fixedly connected to a support plate. A side guard plate is fixedly attached to the upper side of the support plate. The support plates located at the same end of the rotating rods are fixedly connected to each other with a seat plate. The upper side of the seat plate is provided with a positioning groove for positioning and embedding the bottom of the material frame. One of the rotating shafts is driven to rotate by a first motor fixedly mounted on the support frame.

[0015] Furthermore, the solution furnace is positioned directly above the workstation conversion assembly, with its furnace opening located below it, and an isolation door structure for controlling its opening and closing is provided at the furnace opening.

[0016] Furthermore, the first transmission machine is divided into multiple transmission structures along its transmission direction. Along the direction away from the workstation conversion component to the direction closer to the workstation conversion component, the transmission speed of the multiple transmission structures increases sequentially, and the single transmission distance of each transmission structure decreases sequentially.

[0017] Furthermore, the cooling water tank is located directly below the workstation conversion assembly, and a cooling water storage cavity is formed inside the cooling water tank. The cross-sectional shape of the cooling water storage cavity is arc-shaped, and its center of arc is located on the rotation axis of the rotating shaft.

[0018] Furthermore, the material support structure includes a support platform, with a lifting platform positioned directly above the support platform. Several second hydraulic cylinders for driving the lifting platform up and down are mounted on the support platform. A second electric telescopic rod is mounted on the lifting platform, with a wheel rod connected to the push rod head. Several upper support rollers are evenly distributed along the length of the wheel rod, with the upper side of each upper support roller protruding from the upper surface of the wheel rod. Two second guide rods are symmetrically distributed on both sides of the second electric telescopic rod, with one end of each guide rod fixedly connected to the wheel rod, and the other ends of each guide rod slidably connected to second guide holes corresponding to the positions on the lifting platform.

[0019] Furthermore, each end of the wheel rod is connected to a bracket, and each bracket has two or more wheel frames on its lower side. The lower end of the wheel frame is rotatably equipped with a lower support roller. The two sides of the support platform are provided with wheel rails for rolling contact and support with the lower support rollers. The cross-sectional shape of the wheel rails is L-shaped.

[0020] Furthermore, a balance frame is connected between the ends of the two brackets away from the wheel rod. The balance frame has a U-shaped outline and several detachable weight blocks are installed on the balance frame.

[0021] Furthermore, the push rod drive structure includes a third electric telescopic rod, which is fixedly mounted on the second transmission machine via a second fixed base. A second motor is provided at the push rod head end of the third electric telescopic rod, and the output shaft end of the second motor is fixedly connected to the push rod head end of the third electric telescopic rod. A push-pull rod is connected to the outside of the second motor.

[0022] Furthermore, the present invention also provides a method for using an aluminum alloy solution heat treatment apparatus, comprising the following steps:

[0023] S1: The first station is located at the position of the second conveyor, the second station is located at the position of the solid solution furnace, the third station is located at the position of the cooling water tank, and the fourth station is located at the position of the first conveyor. The first, second, third, and fourth stations are distributed at equal angles of 90 degrees.

[0024] S2: The second conveyor transports the material frame carrying the aluminum alloy workpiece toward the station conversion assembly. At this time, the first motor drives the rotating rod to be horizontally distributed. When the material frame moves to the upper support roller of the material support structure, the position of the material frame is adjusted in conjunction with the push rod drive structure. The limiting column limits the position of the material frame so that the material frame is directly above the positioning groove. The second hydraulic cylinder adjusts the height of the lifting platform to decrease. After the bottom of the material frame is embedded in the positioning groove, the second hydraulic cylinder continues to adjust the height of the lifting platform to decrease. The upper support roller and the frame edge of the material frame separate from each other in the vertical direction. Then the second electric telescopic rod drives the upper support roller and the frame edge to separate from each other in the horizontal direction.

[0025] S3: The station conversion component drives the material frame to rotate from the first station to the second station. At this time, the isolation door structure is in the open state of the solution furnace opening. The hydraulic cylinder above drives the support plate to move upward, thereby moving the material frame into the solution furnace until the seat plate seals the solution furnace opening. Then the aluminum alloy workpiece can be dissolved in the solution furnace.

[0026] S4: After the solution treatment is completed, the hydraulic cylinder drives the pallet to move downward, thereby moving the material frame out of the solution furnace. The isolation door structure closes the furnace opening again to keep it warm and prevent heat loss. The station conversion component moves the material frame from the second station to the third station for rapid cooling.

[0027] S5: The station conversion component once again drives the material frame to rotate from the third station to the fourth station. At this time, the material support structure lifts and removes the material frame, and the push rod drive structure drives the material frame to move onto the first conveyor under the rolling support of the upper support rollers. The material frame is then heated in the aging furnace at an aging temperature of 160℃-220℃. Meanwhile, the second conveyor continues to feed the material frame to the station conversion component.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. Through the coordinated operation of the workstation conversion components, solution furnace, isolation door structure, aging furnace, first conveyor, material support structure, second conveyor and push rod drive structure, the material frame can be automatically transferred between various processing stages such as feeding, solution, cooling and aging, realizing a continuous operation throughout the entire process.

[0031] 2. The solution furnace opening is set downwards, and with the alternating sealing design of the isolation door structure and the seat plate, the furnace opening can be quickly closed after the material frame enters or exits, reducing heat loss, ensuring stable temperature inside the solution furnace, and improving the solution quality of aluminum alloy workpieces.

[0032] 3. The push rod drive structure serves to drive and position the material frame between the first conveyor and the material support structure, as well as between the second conveyor and the material support structure. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] See Figures 1-8 As shown, this invention provides a solution heat treatment apparatus for aluminum alloy processing, including a base 1 and a support frame 101 mounted on the base 1. A solution furnace 3 for solution treatment of aluminum alloy workpieces is mounted on the upper side of the support frame 101, and a cooling water tank 12 is mounted on the lower side of the support frame 101. In practical applications, a temperature sensor can also be installed on the cooling water tank 12 to monitor the temperature of the cooling water in the tank in real time, as well as the water circulation system. When the water temperature is too high, a water pump discharges the hot water and introduces new cooling water to achieve water circulation and maintain the water temperature within a suitable range. A first conveyor 6 for conveying the processed material frame 11 outwards and a conveyor 6 for guiding the material frame 11 containing the aluminum alloy workpiece to the workstation are respectively mounted on both sides of the support frame 101. The conversion component 2 includes a second conveyor 8; a material support structure 7 for supporting and adjusting the height of the material frame 11 is provided between the first conveyor 6 and the station conversion component 2, and between the second conveyor 8 and the station conversion component 2; an aging furnace 5 is provided at the position of the first conveyor 6 for heating and aging the material frame 11 conveyed thereon; a station conversion component 2 is provided on the support frame 101 for switching the material frame 11 between the solution furnace 3, the first conveyor 6, the cooling water tank 12, and the second conveyor 8; a push rod drive structure 9 is provided on the second conveyor 8 for pushing the material frame 11 from the second conveyor 8 to the corresponding material support structure 7 and for pushing the material frame 11 from the corresponding material support structure 7 to the first conveyor 6. A frame edge 1101 is provided on the upper outer edge of the material frame 11.

[0045] See instruction manual attached Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, the workstation conversion assembly 2 includes two parallel rotating rods 202. The middle part of the rotating rods 202 is rotatably connected to the support frame 101 via a rotating shaft 203. Both ends of the rotating rods 202 are rotatably connected to fixed blocks 204. Each fixed block 204 is fixedly equipped with a hydraulic cylinder 209. The push rod head of the hydraulic cylinder 209 is fixedly connected to a support plate 206. A side guard plate 205 is fixedly fixed on the upper side of the support plate 206. The support plates 206 located at the same end of the rotating rods 202 are fixedly connected to each other with a seat plate 207. The upper side of the seat plate 207 is provided with a positioning groove 208 for positioning and embedding the bottom of the material frame 11. One of the rotating shafts 203 is driven to rotate by a first motor 201 fixedly mounted on the support frame 101. Through the above-described specific structural design, when the workstation conversion component 2 is working, the first motor 201 first drives one of the rotating shafts 203 to rotate, which in turn drives two parallel rotating rods 202 to rotate around the rotating shaft 203. The fixed blocks 204 at both ends of the rotating rods 202 rotate under the gravity of the side guard plate 205 and the seat plate 207, so that the seat plate 207 always remains horizontal. When the rotating rod 202 rotates to the corresponding workstation, the hydraulic cylinder 209 drives the push rod to extend and retract, which drives the seat plate 207 to move through the support plate 206. The side guard plate 205 protects the side of the material frame 11, realizing the conversion and transfer of the material frame 11 between various workstations. Among them, the first motor 201 provides power for the rotation of the rotating rod 202 to realize the workstation switching. In actual applications, a reducer is installed at the output shaft end of the first motor 201.

[0046] See instruction manual attached Figure 3 , Figure 4 and Figure 8As shown, the solution furnace 3 is positioned directly above the workstation conversion assembly 2, with its furnace opening located below it. The furnace opening of the solution furnace 3 is equipped with an isolation door structure 4 for controlling its opening and closing. The isolation door structure 4 includes a door seat 401, and a switch door 406 is movably disposed within the door seat 401. Two parallel first guide rods 405 are fixedly connected to one side of the switch door 406. The other ends of the two first guide rods 405 slide through the door seat 401 and are fixedly connected to a connecting plate 404. A first electric telescopic rod 403 is fixedly disposed on the door seat 401. The push rod head of the first electric telescopic rod 403 is fixedly connected to the connecting plate 404. The first electric telescopic rod 403 is fixedly disposed on the solution furnace 3 through a first fixed seat 402. In practical applications, the solution furnace 3 is positioned directly above the workstation conversion component 2 with its opening facing downwards, facilitating the workstation conversion component 2 to feed the material frame 11 into the furnace for solution treatment. The isolation door structure 4 at the furnace opening is driven by the first electric telescopic rod 403 to drive the connecting plate 404, which in turn moves the first guide rod 405 and the on / off door 406 within the door seat 401, thereby controlling the opening and closing of the furnace opening. When the material frame 11 needs to enter the solution furnace 3, the on / off door 406 opens to ensure the smooth entry and exit of the material frame 11. After solution treatment, the material frame 11 is removed from the solution furnace 3, and the on / off door 406 closes, sealing the furnace opening in conjunction with the seat plate 207 to reduce heat loss, ensure stable temperature inside the solution furnace 3, and improve the solution treatment effect.

[0047] The first conveyor 6 is divided into multiple conveyor segments along its conveying direction. The conveying speed of each segment increases sequentially from the direction away from the station conversion component 2 to the direction closer to the station conversion component 2, while the single conveying stroke of each segment decreases sequentially. In practical applications, the multi-segment conveying structure of the first conveyor 6 exhibits the characteristics of increasing conveying speed and decreasing single conveying stroke in the direction from the direction away from the station conversion component 2 to the direction closer to the station conversion component 2. This facilitates the concentration of the material frame 11 within the aging furnace 5 in the direction away from the station conversion component 2, while maintaining the requirement for long-term aging treatment.

[0048] See instruction manual attached Figure 2 As shown, the cooling water tank 12 is located directly below the workstation conversion assembly 2. A cooling water storage cavity is formed inside the cooling water tank 12. The cross-sectional shape of the cooling water storage cavity is arc-shaped and its center is located on the rotation axis of the rotating shaft 203.

[0049] See instruction manual attached Figure 2 , Figure 3 and Figure 7As shown, the material support structure 7 includes a support platform 701, a lifting platform 702 is arranged directly above the support platform 701, a plurality of second hydraulic cylinders 703 are arranged on the support platform 701 for driving the lifting platform 702 to move up and down, a second electric telescopic rod 713 is arranged on the lifting platform 702, the push rod head of the second electric telescopic rod 713 is connected to a wheel rod 709, a plurality of upper support rollers 711 are evenly distributed along the length of the wheel rod 709, the upper side of the upper support rollers 711 protrudes from the upper surface of the wheel rod 709, two second guide rods 710 are arranged symmetrically distributed on both sides of the second electric telescopic rod 713 with the second guide rod 713 as the center, one end of the two second guide rods 710 is fixedly connected to the wheel rod 709, and the other end of the two second guide rods 710 is slidably connected to the second guide sliding hole opened at the corresponding position of the lifting platform 702. The wheel rod 709 has brackets 704 connected to both ends. Each bracket 704 has two or more wheel frames 707 on its lower side. The lower end of each wheel frame 707 is rotatably equipped with a lower support roller 708. The support platform 701 has wheel rails 714 on both sides for rolling contact and support with the lower support rollers 708. The cross-sectional shape of the wheel rails 714 is L-shaped. A balance frame 705 is connected between the ends of the two brackets 704 away from the wheel rod 709. The balance frame 705 has a U-shaped outline and several detachable counterweights 706 are mounted on it. Through the above-mentioned specific structural design, the support platform 701 first provides a stable support foundation. When the material frame 11 needs to be transferred to the workstation conversion component 2 or from there to the first conveyor 6, the second hydraulic cylinder 703 drives the lifting platform 702 to rise, so that the upper support roller 711 supports the frame edge 1101 of the material frame 11. At this time, the second electric telescopic rod 713 pushes the wheel rod 709, which, together with the guiding action of the second guide rod 710, allows the upper support roller 711 to support the material frame 11 and assist its horizontal movement. The brackets 704 at both ends of the wheel rod 709 roll on the L-shaped wheel rail 714 through the lower support rollers 708 on the wheel frame 707, enhancing the stability of the overall structural movement. At the same time, the counterweight block 706 on the balance frame 705 can adjust the balance and prevent the structure from tilting. When the material frame 11 needs to be placed into the positioning slot 208 of the workstation conversion component 2 or transferred to the first conveyor 6, the second hydraulic cylinder 703 drives the lifting platform 702 to descend, so that the material frame 11 is in place. Then, the second electric telescopic rod 713 drives the upper support roller 711 to retract, completing the handover of the material frame 11.

[0050] See instruction manual attached Figure 2 and Figure 5As shown, the push rod drive structure 9 includes a third electric telescopic rod 901, which is fixedly mounted on the second conveyor 8 via a second fixed base 902. A second motor 903 is provided at the push rod head of the third electric telescopic rod 901, and the output shaft end of the second motor 903 is fixedly connected to the push rod head of the third electric telescopic rod 901. A push-pull rod 904 is connected to the outside of the second motor 903. In practical applications, the push rod drive structure 9 serves to drive and position the material frame 11 between the first conveyor 6 and the material support structure 7, and between the second conveyor 8 and the material support structure 7.

[0051] Working principle of the invention:

[0052] When in use, the second conveyor 8 position is the first station, the solid solution furnace 3 position is the second station, the cooling water tank 12 position is the third station, and the first conveyor 6 position is the fourth station. The first, second, third, and fourth stations are distributed at an equal angle of 90 degrees.

[0053] The second conveyor 8 transports the material frame 11 carrying the aluminum alloy workpiece toward the station conversion component 2. At this time, the first motor 201 drives the rotating rod 202 to be horizontally distributed. When the material frame 11 moves to the upper support roller 711 of the material support structure 7, the position of the material frame 11 is adjusted by the push rod drive structure 9. The limiting column 712 limits the position of the material frame 11 so that the material frame 11 is directly above the positioning groove 208. The second hydraulic cylinder 703 adjusts the height of the lifting platform 702. After the bottom of the material frame 11 is embedded in the positioning groove 208, the second hydraulic cylinder 703 continues to adjust the height of the lifting platform 702. The upper support roller 711 and the frame edge 1101 of the material frame 11 separate from each other in the vertical direction. Then the second electric telescopic rod 713 drives the upper support roller 711 and the frame edge 1101 to separate from each other in the horizontal direction.

[0054] The station conversion component 2 drives the material frame 11 to rotate from the first station to the second station. At this time, the isolation door structure 4 is in the open state of the furnace opening of the solution furnace 3. The hydraulic cylinder 209 located above drives the support plate 206 to move upward, thereby moving the material frame 11 into the solution furnace 3 until the seat plate 207 seals the furnace opening of the solution furnace 3. Then the aluminum alloy workpiece can be dissolved in the solution furnace 3.

[0055] After the solution treatment is completed, the hydraulic cylinder 209 drives the pallet 206 to move downward, thereby moving the material frame 11 out of the solution furnace 3. The isolation door structure 4 closes the furnace opening of the solution furnace 3 again to keep it warm and prevent heat loss. The station conversion component 2 moves the material frame 11 from the second station to the third station for rapid cooling.

[0056] The station conversion component 2 drives the material frame 11 to rotate from the third station to the fourth station again. At this time, the material support structure 7 lifts and removes the material frame 11. The push rod drive structure 9 drives the material frame 11 to move onto the first conveyor 6 under the rolling support of the upper support roller 711, and heats it in the aging furnace 5 at an aging temperature of 160℃-220℃. Meanwhile, the second conveyor 8 continues to feed the material frame 11 to the station conversion component 2.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

10. A method of using an aluminum alloy processing solution heat treatment apparatus, comprising the aluminum alloy processing solution heat treatment apparatus according to any one of claims 1-9, characterized in that: Includes the following steps: S1: The first station is located at the position of the second conveyor (8), the second station is located at the position of the solid solution furnace (3), the third station is located at the position of the cooling water tank (12), and the fourth station is located at the position of the first conveyor (6). The first, second, third, and fourth stations are distributed at an equal angle of 90 degrees. S2: The second conveyor (8) transports the material frame (11) carrying the aluminum alloy workpiece toward the station conversion assembly (2). At this time, the first motor (201) drives the rotating rod (202) to be horizontally distributed. When the material frame (11) moves to the upper support roller (711) of the material support structure (7), the push rod drive structure (9) drives and adjusts the position of the material frame (11). The limiting post (712) limits the position of the material frame (11) so that the material frame (11) is located in the positioning groove. Directly above (208), the second hydraulic cylinder (703) adjusts the height of the lifting platform (702) to decrease. After the bottom of the material frame (11) is embedded in the positioning groove (208), the second hydraulic cylinder (703) continues to adjust the height of the lifting platform (702) to decrease. The upper support roller (711) and the frame edge (1101) of the material frame (11) separate from each other in the vertical direction. Then the second electric telescopic rod (713) drives the upper support roller (711) and the frame edge (1101) to separate from each other in the horizontal direction. S3: The station conversion component (2) drives the material frame (11) to rotate from the first station to the second station. At this time, the isolation door structure (4) is in the open state of the furnace mouth of the solution furnace (3). The hydraulic cylinder (209) located above drives the pallet (206) to move upward, thereby driving the material frame (11) to move into the solution furnace (3) until the seat plate (207) seals the furnace mouth of the solution furnace (3). Then the aluminum alloy workpiece can be dissolved in the solution furnace (3). S4: After the solution is completed, the hydraulic cylinder (209) drives the pallet (206) to move downward, thereby moving the material frame (11) out of the solution furnace (3). The isolation door structure (4) closes the furnace opening of the solution furnace (3) again to prevent heat loss. The station conversion component (2) moves the material frame (11) from the second station to the third station for rapid cooling. S5: The station conversion component (2) drives the material frame (11) to rotate from the third station to the fourth station again. At this time, the material support structure (7) lifts and removes the material frame (11), and the push rod drive structure (9) drives the material frame (11) to move to the first conveyor (6) under the rolling support of the upper support roller (711), and heats it in the aging furnace (5) at an aging temperature of 160℃-220℃. Meanwhile, the second conveyor (8) continues to feed the material frame (11) to the station conversion component (2).
