Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal forging, and specifically to an aluminum alloy precision casting forming device and process. Background Technique

[0002] As a lightweight and high-strength metal material, aluminum alloy plays a crucial role in the field of modern industrial manufacturing, especially in the fields of aerospace, automotive manufacturing, and precision machinery. With the progress of technology and the upgrading of demands, the requirements for the precision, complexity, and overall performance of aluminum alloy parts are increasing day by day. Traditional casting methods have become difficult to meet these stringent requirements in some aspects. Therefore, aluminum alloy precision casting technology has emerged and is constantly developing and growing.

[0003] For example, in the patent document with the prior art publication number CN112719237B, this patent document belongs to the technical field of bearing processing equipment, and specifically to a rapid forging die for bearing rings, including a casting device, a spraying device, a material taking device, and a pouring device. Its technical solution is: a support seat is provided at the bottom of the casting device, the casting device includes a first base, the first base is fixedly installed on the top of the support seat, a spraying device is provided on the right side of the casting device, the spraying device includes a moving plate, a first chute is opened on one side of the top of the support seat, the moving plate is installed on the inner wall of the first chute, a material taking device is provided on the left side of the casting device. This patent document drives the centrifugal barrel to rotate at a high speed through a turntable, injects liquid metal into the cavity through a first pouring barrel, and the molten metal bears multiple times of gravity through the centrifugal force generated by the high-speed rotation of the centrifugal barrel, and finer particles and slag are discharged from the surface during solidification, having the effects of reducing the scrap rate of bearing rings and high productivity.

[0004] In the current centrifugal forming process of aluminum alloy precision casting, liquid metal is accurately injected into the cavity of a rotating mold through a pouring barrel, and precision forging is completed by means of centrifugal force. However, an issue that cannot be ignored in this process is that after the hot metal liquid is forged and formed, its hot surface will quickly release a large amount of heat energy. In order to maintain the stability of the production process and ensure the quality of castings, a special cooling structure is usually equipped to dissipate this heat in a timely manner. Although such cooling measures are crucial for ensuring production efficiency and the performance of castings, unfortunately, a large amount of heat energy is simply discharged into the environment during this process, which not only causes significant energy waste. For this reason, this application proposes an aluminum alloy precision casting forming device and process. Summary of the Invention

[0014] Preferably, a plurality of air grooves are evenly formed on both sides of the transmission cylinder, and a piston is fixedly connected to one end of the transmission rod extending into the transmission cylinder.

[0015] Preferably, the recovery component includes a copper pipe fixedly connected inside the side frame, and cold water is stored inside the copper pipe. A side plate is fixedly connected inside the air pipe. A connecting rod is rotatably connected inside the side pipe. One end of the connecting rod extends into the air pipe and is fixedly connected with a plurality of second blades.

[0018] The present invention also provides an aluminum alloy precision casting forming process, which includes the following steps:

[0019] S1. First, pour the melt in the hopper into the mold and drive it to rotate for centrifugal forging at the same time;

[0020] S2. When the melt in the mold is forged and formed and placed on the outer surface of the air pipe, start the air supply component to cool and clean the mold;

[0021] S3. When the air supply component operates, it will drive the extension component to operate and expand a plurality of sliding pipes to extend into the mold, improving the cooling and cleaning efficiency;

[0022] S4. At the same time, after the gas absorbs heat after being cooled, it enters the air return disc and the waste heat is recovered by the recovery component.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By setting up a double-headed plate, two molds, and a transmission disk driven by a driving frame, the rapid alternating use of the molds is achieved. When one mold is forging, the other mold can be prepared to receive new molten metal, thus significantly reducing the waiting time and improving the overall production efficiency. The second guide rail drives the hopper to move precisely, ensuring that the molten metal can be accurately injected into the mold, reducing the complexity and error of manual operation and improving the casting precision. The design of the air pipe and the rotating pipe allows gas to circulate between the two molds, with one rotating pipe sucking air and the other jetting air for mold cooling and cleaning. At the same time, the combination of the filter cartridge and the scraping rack inside the box shell, as well as the rotating rod and the first blade driven by the driving motor, ensures the filtration and cleaning of the gas, preventing impurities from contaminating the mold and the workpiece. The meshing design of the incomplete gear and the gear, as well as the interaction between the teeth and the internal teeth, enables the filter cartridge to rotate slowly while the gas is flowing, contacting the scraping rack for cleaning, avoiding filter cartridge blockage, and extending the service life of the equipment. The combination of the sliding pipe and the transmission rod, as well as the extension assembly (including the groove plate and the limit wheel), enables the gas to more effectively cover the inside of the mold, improving the cooling and cleaning effect. At the same time, the design of the transmission blade enables the gas flow to drive the transmission rod to rotate when the gas flows, further enhancing the extension of the sliding pipe and the gas coverage area. When the mold finishes forging, the cylinder drives the box shell and the rotating pipe close to the mold, and the surface of the mold is automatically cleaned using the suction and jetting forces of the gas, reducing the need for manual cleaning and improving the production efficiency and safety.

[0025] 2. The air return disk is connected to the rotating tube through a side tube, effectively absorbing the heat released after the die forging. The gas carries this heat and flows around the copper tube, heating the cold water in the copper tube to achieve waste heat recovery. This not only reduces energy waste but also provides additional hot water resources for the factory, which can be used in other production processes or for heating, improving the overall energy utilization efficiency. The second blade and the fan blade on the connecting rod are ingeniously designed. Using the power generated by the rapid flow of gas in the air pipe, they drive the connecting rod to rotate, thereby enhancing the gas flow in the side tube. This not only improves the air intake intensity of the air return disk, ensures the effective cooling and cleaning of the die, but also accelerates the gas circulation, improving the response speed and efficiency of the entire system. The setting of the flow splitter effectively guides the gas flow direction, enabling some gas to flow back to the return pipe after heating the copper tube and flow through the copper tube again, further improving the waste heat recovery efficiency. This design ensures the full utilization of heat and reduces heat dissipation. The entire waste heat recovery system realizes automatic control through the natural flow and mechanical transmission of gas, without additional manual operation. This not only simplifies the operation process, reduces labor costs, but also improves the safety and stability of production. The addition of the waste heat recovery system reduces heat emissions during the casting process and reduces the thermal pollution to the environment. At the same time, the recovered hot water resources can be used in other production processes, reducing energy consumption and carbon emissions, which is in line with the current green and sustainable development concept. The combined use of the air return disk and the sliding tube not only enhances the cooling effect of the die but also removes impurities and oxides on the die surface through gas circulation, helping to extend the service life of the die and improve the casting quality.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3, the present invention provides a technical solution: a precision casting forming device for aluminum alloy, including two molds 103 and a hopper 106. A base 100 is provided below the mold 103. A secondary frame 101 is fixedly connected to the top of the base 100. A first guide rail 105 is fixedly connected to one side of the secondary frame 101. A reduction motor 104 adapted to the outer surface of the first guide rail 105 is provided. The output end of the reduction motor 104 is fixedly connected to a double-headed plate 102. The two molds 103 are rotatably connected to both ends of the double-headed plate 102. A plurality of transmission discs 110 for driving the rotation of the mold 103 are provided on the top of the base 100. A driving frame 109 for driving the rotation of the plurality of transmission discs 110 is fixedly connected to the top of the base 100. A support 107 is fixedly connected to one side of the base 100. A second guide rail 108 for driving the movement of the hopper 106 is fixedly connected to the top of the support 107. By providing the driving frame 109, the transmission disc 110 can be driven to rotate, so that the mold 103 located below the double-headed plate 102 rotates. By providing the second guide rail 108, the hopper 106 can be driven to move, so that the melt can smoothly enter the mold 103. By setting the cooperation of the two molds 103 and the double-headed plate 102, one forging and the other disassembly can be realized, thereby improving the forging efficiency.

[0043] Further, please refer to Figure 4 , Figure 5 and Figure 6 , and further includes an air pipe 200, which is constructed to be hollow and rotatably connected with a rotating pipe 201 at both ends. A box shell 202 is fixedly connected to the middle end of the air pipe 200. A filter cartridge 205 for filtering gas is provided inside the box shell 202, and an air delivery component for driving the one-way flow of gas. The air delivery component includes a scraping frame 204 fixedly connected to the inside of the box shell 202, and the outer surface of the filter cartridge 205 is in contact with the scraping frame 204. A driving motor 208 is fixedly connected to the top of the box shell 202. The output end of the driving motor 208 is fixedly connected to a rotating rod 206 extending into the filter cartridge 205. A plurality of first blades 207 are uniformly fixedly connected to the outer surface of the rotating rod 206. By providing the air delivery component, the gas delivery can be effectively realized, so that one rotating pipe 201 sucks air and the other rotating pipe 201 sprays the absorbed gas, which can be adapted to the synchronous processing of the two molds 103 and improve the processing efficiency.

[0044] Among them, the bottom of the rotating rod 206 is fixedly connected with an incomplete gear 209. Inside the box shell 202, a gear 211 meshing with the incomplete gear 209 is rotatably connected. The top of the gear 211 is fixedly connected with teeth 210. An internal gear 212 meshing with the teeth 210 is fixedly connected to the inner wall of the filter cartridge 205. One side of the auxiliary frame 101 is fixedly connected with a cylinder 203. The output end of the cylinder 203 is fixedly connected to the box shell 202. Among them, the air pipe 200 penetrates through the auxiliary frame 101, so that the cylinder 203 can drive the rotating pipe 201 to move, thereby cleaning the subsequent mold 103 and dissipating heat from the workpiece. By setting the cooperation of the incomplete gear 209 and the gear 211, the rotation speed of the teeth 210 can be slowed down, so that the teeth 210 slowly drive the filter cartridge 205 to rotate, and the filter cartridge 205 abuts against the scraping frame 204 to realize the cleaning of the filter cartridge 205.

[0045] Furthermore, please refer to Figure 7 , Figure 8 and Figure 9 , and also includes a sliding pipe 300, which is constructed in multiple numbers and is evenly slidably connected to the outer surfaces of the two rotating pipes 201. Inside both of the two rotating pipes 201, a transmission cylinder 304 is fixedly connected. Inside the transmission cylinder 304, a transmission rod 301 is arranged, and an extension assembly for driving the multiple sliding pipes 300 to expand is arranged on the outer surface of the transmission rod 301. The extension assembly includes multiple groove plates 307 evenly fixedly connected to the outer surface of the transmission rod 301, and one end of each of the multiple sliding pipes 300 is rotatably connected with multiple limit wheels 308 that can abut against the inclined surfaces of the groove plates 307. Inside the air pipe 200, a support frame 302 for supporting the transmission rod 301 is fixedly connected. A transmission blade 303 is fixedly connected to the outer surface of the transmission rod 301.

[0046] Among them, please refer to Figure 8 , Figure 9 and Figure 10 , multiple air grooves 305 are evenly opened on both sides of the transmission cylinder 304. One end of the transmission rod 301 extending into the transmission cylinder 304 is fixedly connected with a piston 306. This makes the forged mold 103 move a quarter of a circle and approach the direction of the rotating pipe 201. At this time, this rotating pipe 201 generates jet air, while the other rotating pipe 201 generates suction, so that the mold 103 that has just removed the workpiece approaches the other rotating pipe 201 to clean the mold 103, thereby completing the forging, cooling, material taking and cleaning work of the mold 103.

[0047] Specifically, after the melt in the mold 103 is forged and formed, the driving frame 109 stops running. Then, operate the second guide rail 108 to drive the discharge pipe of the hopper 106 away from the mold 103. Operate the reduction motor 104 to drive the double-headed plate 102 to rotate a quarter of a turn to change the position of the mold 103. At the same time, operate the cylinder 203 to drive the box shell 202 to move in the direction close to the auxiliary frame 101, so that the two rotating pipes 201 are respectively inserted into the two molds 103. Subsequently, turn on the driving motor 208 to drive the rotating rod 206 to rotate, which drives the multiple first blades 207 to rotate, causing suction to be generated in one rotating pipe 201 and air to flow out from the other rotating pipe 201. At the same time, the gas will be filtered through the filter cartridge 205. When the rotating rod 206 rotates, it will drive the incomplete gear 209 to rotate together with it, which drives the gear 211 to rotate, causing the tooth 210 to intermittently engage with the internal teeth 212, thereby driving the filter cartridge 205 to rotate slightly, so as to continuously contact the scraping frame 204 to clean the filter cartridge 205. When the gas flows in the rotating pipe 201, it will drive the piston 306 to move in the transmission cylinder 304, so that the gas can pass through the piston 306 and pass through the multiple air grooves 305 for ventilation. At the same time, when the piston 306 moves, it will pull the transmission rod 301 to move, causing the multiple groove plates 307 on its surface to move together with it, thereby driving the multiple sliding pipes 300 to extend outward into the mold 103, improving the suction and spraying force. At the same time, when the air flow passes through the transmission blade 303, it will drive the transmission rod 301 to rotate, causing the groove plate 307 to pull the limit wheel 308 to move, and then driving the rotating pipe 201 to rotate to increase the gas coverage area.

[0048] In summary, by setting the double-headed plate 102, the two molds 103, and the transmission disc 110 driven by the drive frame 109, the rapid alternate use of the molds is achieved. When one mold is forging, the other mold can be prepared to receive new molten metal, thus significantly reducing the waiting time and improving the overall production efficiency. The second guide rail 108 drives the hopper 106 to move precisely, ensuring that the molten metal can be accurately injected into the mold, reducing the complexity and error of manual operation, and improving the casting precision. The design of the air pipe 200 and the rotating pipe 201 allows gas to circulate between the two molds, with one rotating pipe sucking air and the other jetting air for cooling and cleaning the molds. At the same time, the combination of the filter cartridge 205 and the scraping frame 204 inside the box shell 202, as well as the rotating rod 206 and the first blade 207 driven by the drive motor 208, ensures the filtration and cleaning of the gas, preventing impurities from contaminating the molds and workpieces. The meshing design of the incomplete gear 209 and the gear 211, as well as the interaction between the teeth 210 and the internal teeth 212, enables the filter cartridge 205 to rotate slowly while the gas is flowing, contacting the scraping frame 204 for cleaning, avoiding filter cartridge blockage, and extending the service life of the equipment. The combination of the sliding pipe 300 and the transmission rod 301, as well as the extension assembly including the groove plate 307 and the limit wheel 308, enables the gas to more effectively cover the inside of the mold, improving the cooling and cleaning effect. At the same time, the design of the transmission blade 303 enables the gas flow to drive the transmission rod to rotate when the gas flows, further enhancing the extension of the sliding pipe and the gas coverage area. When the mold finishes forging, the cylinder 203 drives the box shell 202 and the rotating pipe 201 close to the mold, and the surface of the mold is automatically cleaned by the suction and jet force of the gas, reducing the need for manual cleaning and improving the production efficiency and safety.

[0049] Embodiment 2: Please refer to Figure 11 、 Figure 12 and Figure 13 , the present invention also provides a technical solution. The difference from the technical solution of Embodiment 1 is: An aluminum alloy precision casting forming device further includes a return air disc 400, which is arranged on one side of the mold 103 for absorbing the gas ejected from the sliding pipe 300. One side of a rotating pipe 201 is communicated with a side pipe 402, one end of the side pipe 402 is communicated with a side frame 401 for supporting the return air disc 400, and a recovery assembly for absorbing the heat of the gas is arranged inside the side frame 401. By setting the recovery assembly, the waste heat can be absorbed for recovery, thereby absorbing the heat inside the mold 103 after forging.

[0050] Furthermore, please refer to Figure 12 、 Figure 13 and Figure 14The recovery component includes a copper tube 403 fixedly connected to the inside of the side frame 401, and the copper tube 403 stores cold water. The inside of the air pipe 200 is fixedly connected to the side plate 404, and the inside of the side pipe 402 is rotatably connected to the connecting rod 405. One end of the connecting rod 405 extends to the inside of the air pipe 200 and is fixedly connected to a plurality of second blades 406. The other end of the connecting rod 405 extends to the inside of the side pipe 402 and is fixedly connected to a plurality of fan blades 407. The inside of the side pipe 402 is fixedly connected to a diverter plate 408, and one side of the side pipe 402 is connected to a return flow. Tube 409, one side of the copper tube 403 is connected to an inlet pipe 410, and the top of the inlet pipe 410 is connected to a return pipe 411. When the gas in the air pipe 200 flows rapidly, low pressure will be generated, causing the gas in the side pipe 402 to flow into the air pipe 200, thereby causing suction in the return air disk 400. At the same time, the second blade 406 rotates to drive the fan blade 407 to rotate to increase the gas flow in the side pipe 402, thereby increasing the suction strength of the return air disk 400. At the same time, a diverter plate 408 is provided to guide the gas to flow back to the return pipe 409 and is placed in the side frame 401.

[0051] Specifically, after the gas is ejected through the rotating tube 201, it will carry the heat in the forged mold 103. The airflow drives the second blade 406 to drive the connecting rod 405 to rotate and drive the fan blade 407 to rotate, so that suction is generated in the side tube 402 and the air is sucked from the return air disk 400 to suck away the hot air in the rotating tube 201. The gas will flow through the copper tube 403 to heat the gas inside it, realizing waste heat recovery. The gas will resist the diverter plate 408 and part of the gas will flow back to the return pipe 409 to continue heating the copper tube 403. After the cold water in the copper tube 403 absorbs the heat, the return water pipe 411 is opened to release hot water, and then cold water is poured into the copper tube 403 through the water inlet pipe 410.

[0052] In summary, the air return disk 400 is connected to the rotating pipe 201 through the side pipe 402, effectively absorbing the heat released after the forging of the mold 103. The gas carries this heat and flows around the copper pipe 403, heating the cold water in the copper pipe to achieve the recovery of waste heat. This not only reduces energy waste but also provides additional hot water resources for the factory, which can be used in other production processes or for heating, improving the overall energy utilization efficiency. The second blade 406 and the fan blade 407 on the connecting rod 405 are ingeniously designed. Utilizing the power generated by the rapid flow of the gas in the air pipe 200, they drive the connecting rod to rotate, thereby enhancing the gas flow in the side pipe 402. This not only improves the air intake intensity of the air return disk 400, ensuring the effective cooling and cleaning of the mold 103, but also accelerates the gas circulation, improving the response speed and efficiency of the entire system. The setting of the flow dividing plate 408 effectively guides the gas flow, enabling some gas to flow back to the return pipe 409 after heating the copper pipe 403 and flowing through the copper pipe again, further improving the waste heat recovery efficiency. This design ensures the full utilization of heat and reduces heat dissipation. The entire waste heat recovery system realizes automatic control through the natural flow and mechanical transmission of the gas, without additional manual operation. This not only simplifies the operation process, reduces labor costs, but also improves the safety and stability of production. The addition of the waste heat recovery system reduces heat emissions during the casting process and reduces the thermal pollution to the environment. At the same time, the recovered hot water resources can be used in other production processes, reducing energy consumption and carbon emissions, which is in line with the current green and sustainable development concept. The combined use of the air return disk 400 and the sliding pipe 300 not only enhances the cooling effect of the mold 103 but also removes impurities and oxides on the mold surface through gas circulation, helping to extend the service life of the mold and improve the casting quality.

[0053] Embodiment 3: Please refer to Figures 1 to 14 , the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1 in that: an aluminum alloy precision casting process includes the following steps:

[0054] S1. During use, first operate the second guide rail 108 to drive the hopper 106 to move so that its discharge pipe extends into the mold 103 located at the bottom of the double-headed plate 102. At the same time, operate the driving frame 109 to drive the transmission disk 110 to rotate and drive the mold 103 to rotate rapidly. At the same time, pour the melt into the mold 103 to forge and form.

[0055] S2. After the melt in the mold 103 is forged and formed, stop the operation of the drive frame 109, operate the second guide rail 108 to drive the discharge pipe of the hopper 106 away from the mold 103, operate the reduction motor 104 to drive the double-headed plate 102 to rotate a quarter of a circle to change the position of the mold 103. At the same time, operate the cylinder 203 to drive the box shell 202 to move in the direction close to the auxiliary frame 101, so that the two rotating pipes 201 are respectively inserted into the two molds 103. Then, turn on the drive motor 208 to drive the rotating rod 206 to rotate, which drives a plurality of first blades 207 to rotate, so that suction is generated in one rotating pipe 201 and air is discharged from the other rotating pipe 201. At the same time, the gas will be filtered through the filter cartridge 205. When the rotating rod 206 rotates, it will drive the incomplete gear 209 to rotate with it, which drives the gear 211 to rotate, so that the tooth 210 intermittently meshes with the internal teeth 212, thereby driving the filter cartridge 205 to rotate slightly, so as to continuously contact the scraping frame 204 to clean the filter cartridge 205;

[0056] S3. When the gas flows in the rotating pipe 201, it will drive the piston 306 to move in the transmission cylinder 304, so that the gas can pass through the piston 306 and pass through a plurality of air grooves 305 for ventilation. At the same time, when the piston 306 moves, it will pull the transmission rod 301 to move, so that a plurality of groove plates 307 on its surface will move with it, thereby driving a plurality of sliding pipes 300 to extend outward into the mold 103 to improve the suction and spraying force. At the same time, when the air flow passes through the transmission blade 303, it will drive the transmission rod 301 to rotate, so that the groove plate 307 pulls the limit wheel 308 to move, and then drives the rotating pipe 201 to rotate to increase the gas coverage area;

[0057] S4. At the same time, after the gas is ejected from the rotating pipe 201, it will carry the heat in the forged and formed mold 103 to flow. The air flow drives the second blade 406, which drives the connecting rod 405 to rotate and drives the fan blade 407 to rotate, so that suction is generated in the side pipe 402 to suck the hot air in the rotating pipe 201 from the air return disc 400. The gas will flow through the copper pipe 403 to heat the gas inside it, realizing waste heat recovery. When the gas touches the flow dividing plate 408, part of the gas will flow back into the return pipe 409 to continue heating the copper pipe 403.
