Description

A device for hot extrusion cooling and shaping of aluminum profiles Technical Field

[0001] This application relates to the field of aluminum profile hot extrusion cooling and shaping technology, and in particular to an aluminum profile hot extrusion cooling and shaping device. Background Technology

[0002] Aluminum profiles are produced by heating aluminum alloy ingots and then extruding them through die holes of a specific shape under high pressure to obtain the desired cross-sectional profile. They are widely used in building doors, windows, curtain walls, transportation, electronics, and mechanical structures. After hot extrusion, aluminum profiles are at extremely high temperatures and are in a plastic state. Therefore, uneven shrinkage, self-weight, and the release of residual stress may cause deformation of the profiles. Thus, the cooling process often needs to be carried out in conjunction with the shaping process. The aim is to intervene and correct the shape in real time during the critical stage of profile cooling and solidification to ensure that its straightness, flatness, and dimensional accuracy meet stringent standards.

[0003] In existing technologies, the cooling and shaping of aluminum profiles after hot extrusion are typically completed sequentially by multiple independent devices on a continuous production line. This production line generally includes: a traction machine located at the extruder outlet, used to clamp and pull out the profile at a uniform speed; followed by an extended discharge table or conveyor roller conveyor, providing support and conveying for the profile; a cooling system arranged along the conveying path, commonly including forced air cooling boxes, water mist cooling devices, or a combination of both, responsible for cooling the high-temperature profile during its journey; and finally, a straightening machine set at the end of the cooling line, applying complex bending moments and tensile forces to the cooled profile to correct various bending deformations generated in previous processes. These structures are integrated through frames, guide rails, and an electrical control system. Under the pull of the traction machine, the profile sequentially undergoes conveying, cooling, and final mechanical straightening. Each device performs its specific function, with the common goal of transforming the extruded high-temperature profile into a dimensionally accurate cold product.

[0004] Regarding the aforementioned technologies, since cooling and shaping are relatively separate in space and time, and the wider planar portion of the aluminum profile often visibly protrudes or arches outwards in the later stages of cooling, the straightening machine may have limited or no corrective effect on this localized cross-sectional deformation that only fully manifests in the later stages of cooling and solidification and is strongly related to stress release. This results in problems such as poor flatness and inconsistent assembly gaps after the profile leaves the factory, increasing production costs and quality risks. Therefore, improvements are needed. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a hot extrusion cooling and shaping apparatus for aluminum profiles.

[0006] The aluminum profile hot extrusion cooling and shaping device provided in this application adopts the following technical solution: An aluminum profile hot extrusion cooling and shaping device includes a fixed platform, a lifting platform is provided at the upper end of the fixed platform, and an installation groove is opened at the lower end of the lifting platform. A graphite disk is provided in the installation groove. When the aluminum profile is cooled and shaped, the graphite disk abuts against the installation groove and does not move up or down. A graphite plate is provided in the middle of the inner bottom wall of the graphite disk. Multiple sets of fixing frames for fixing the graphite plate are provided on the inner bottom wall of the graphite disk. A detection mechanism for detecting the thickness and curvature of the graphite plate is provided on the lifting platform. A scraping component for scraping the curvature of the graphite plate is provided on the lifting platform. A switching component for switching the graphite plate is provided on the fixed platform.

[0007] By adopting the above technical solution, when aluminum profiles need to be cooled and shaped, a graphite plate with a suitable curvature is placed in a graphite tray and fixed with a fixing frame. Then, the graphite tray is raised into the mounting groove, and the height of the lifting platform is adjusted at the same time to make the curved surface of the graphite plate press against the aluminum profile, providing a precise forming surface. At the same time, the good thermal conductivity of graphite material is used to quickly absorb and dissipate the heat of the aluminum profile, allowing it to cool, solidify and set rapidly under pressure. This ensures that the aluminum profile obtains an accurate cross-sectional shape and stable dimensional accuracy. The testing mechanism checks the thickness and curvature of the graphite plate to ensure that the graphite plate meets the requirements. The scraping component scrapes the curved surface of the graphite plate to repair or adjust the curved surface shape. The switching component switches between different graphite plates to improve production efficiency and adapt to different curved surface requirements.

[0008] Optionally, the detection mechanism includes a lifting frame, a first mounting frame, a first cylinder, a laser rangefinder, and a roughness detection component. The lifting frame is lifted and lowered on the lifting platform. The first mounting frame is slidably disposed at the lower end of the lifting frame. The first cylinder is disposed on the side wall of the lifting frame, and its telescopic end is fixedly connected to the side wall of the first mounting frame. Multiple sets of laser rangefinders are provided, and these sets are vertically arranged at intervals on the first mounting frame. The middle set of laser rangefinders is located directly above the highest point of the graphite plate's curved surface, while the other sets are located on both sides of the highest point of the graphite plate's curved surface. The two sets of laser rangefinders at both ends of the first mounting frame are used to measure the distance between themselves and the inner bottom wall of the graphite disk. The roughness detection component is disposed on the first mounting frame and is used to detect the roughness of the graphite plate's curved surface.

[0009] By adopting the above technical solution, when it is necessary to detect the curvature and thickness of the graphite plate, the first cylinder is activated. The extension end of the first cylinder moves, causing the first mounting frame to move at the lower end of the lifting frame. The movement of the first mounting frame causes multiple sets of laser rangefinders to move. When the movement reaches the designated position, the first cylinder is deactivated and multiple sets of laser rangefinders are activated simultaneously. The multiple sets of laser rangefinders scan the curved surface of the graphite plate synchronously, thereby achieving high-precision and high-efficiency identification of the curvature of the graphite plate. It can also accurately measure the thickness of the graphite plate by comparing the data from the laser rangefinders at both ends with the data from the highest point of the curved surface, realizing quantitative monitoring of the wear of the graphite plate. When the curvature of the graphite plate exceeds the allowable deviation, scraping is required. When the thickness of the graphite plate is close to the minimum usable thickness, the graphite plate needs to be switched. This transforms the entire maintenance process from periodic experience-based maintenance to condition-based predictive maintenance, ensuring that the graphite plate is always in the best working condition. While ensuring product quality consistency, it also optimizes the service life and replacement cycle of the mold, achieving a balance between production efficiency and cost control.

[0010] Optionally, the roughness detection assembly includes an electric telescopic rod, a mounting plate, a positive electrode detection probe, a negative electrode detection probe, a first negative electrode connector, and a second negative electrode connector. The electric telescopic rod is vertically mounted on the first mounting frame, and the mounting plate is mounted on the telescopic end of the electric telescopic rod. Multiple sets of positive electrode detection probes are provided, and these multiple sets of positive electrode detection probes are vertically mounted on the mounting plate at intervals. A placement groove is formed in the middle of the side of the graphite plate away from the laser rangefinder, and the negative electrode detection probe is placed in the placement groove. Wiring grooves are formed on both the graphite disk and the lifting platform. The first negative electrode connector is placed in the wiring groove of the graphite disk, and one end is connected to the negative electrode detection probe. The second negative electrode connector is placed in the wiring groove of the lifting platform, and it movably abuts against the end of the first negative electrode connector away from the negative electrode detection probe.

[0011] By adopting the above technical solution, when it is necessary to detect the roughness of the curved surface of a graphite plate, the electric telescopic rod is activated. The telescopic end of the electric telescopic rod descends, causing the mounting plate to descend. The descent of the mounting plate causes multiple sets of positive detection probes to descend. When the positive detection probes elastically contact the curved surface of the graphite plate, multiple sets of positive detection probes are energized sequentially. Combined with the negative detection probes pre-embedded in the graphite plate and the movable contact of the first and second negative terminals, a detection circuit is automatically formed. After energization, multiple sets of resistance values ​​are recorded sequentially. Since surface roughness directly affects the actual contact area, the difference in contact area will be converted into a change in contact resistance. By comparing the resistance change rate with standard data, the roughness level of the curved surface of the graphite plate can be measured. Multi-point measurement ensures the comprehensiveness and representativeness of the evaluation, thereby realizing rapid, accurate, and automated measurement of the roughness of the curved surface of the graphite plate. This improves the stability and repeatability of the detection, effectively prevents aluminum profile quality defects caused by excessive surface roughness, reduces equipment downtime and manual intervention, lowers maintenance costs, and enhances the intelligent control of the production process and the consistency of product quality.

[0012] Optionally, the scraping assembly includes a second cylinder, a second mounting frame, a third cylinder, a scraper, and a lifting component. The second cylinder is vertically disposed on the upper end of the lifting platform, and its telescopic end is fixedly connected to the lifting frame. The second mounting frame is slidably disposed on the lower end of the lifting frame away from the first mounting frame. The third cylinder is disposed on the side wall of the lifting frame away from the second cylinder, and its telescopic end is fixedly connected to the second mounting frame. The scraper is disposed on the second mounting frame and is used to scrape the curved surface of the graphite plate. The lifting component is disposed on the fixed platform and is used to lift the scraped graphite plate.

[0013] By adopting the above technical solution, when the curvature of the graphite plate exceeds the allowable deviation or has defects, the second cylinder is activated. The telescopic end of the second cylinder descends, causing the lifting frame to descend. The descending lifting frame then causes the second mounting frame to descend, which in turn causes the scraper to descend. Once the scraper has descended to the appropriate height, the second cylinder is deactivated and the third cylinder is activated. The telescopic end of the third cylinder moves, causing the second mounting frame to move at the lower end of the lifting frame. The movement of the second mounting frame then causes the scraper to move, thereby scraping the curved surface of the graphite plate. This improves scraping efficiency, extends the service life of a single graphite plate, reduces spare parts consumption and replacement frequency, and lowers overall production costs.

[0014] Optionally, the lifting component includes a fourth cylinder, and multiple sets of the fourth cylinder are provided. All sets of the fourth cylinder are vertically arranged on the fixed platform, and their telescopic ends are fixedly connected to the lower end of the lifting platform.

[0015] By adopting the above technical solution, after the graphite plate is scraped, the fourth cylinder is activated. The extension end of the fourth cylinder rises, driving the lifting platform to rise. The rising of the lifting platform drives the graphite disk and graphite plate to rise, thereby dynamically compensating for the loss of graphite plate thickness caused by scraping and repair. This ensures the close contact state required for cooling and shaping, and ensures the constant contact heat conduction efficiency and the accuracy of profile contour forming.

[0016] Optionally, the switching assembly includes a fifth cylinder, a third mounting frame, a first drive motor, and a rotating frame. The fifth cylinder is vertically mounted on the inner bottom wall of the fixed platform. The third mounting frame is mounted on the telescopic end of the fifth cylinder. The first drive motor is mounted on the side wall of the third mounting frame. The rotating frame is rotatably mounted on the third mounting frame. The output end of the first drive motor is fixedly connected to the rotating frame. Four sets of graphite disks are spaced apart on the rotating frame, and the four sets of graphite disks are circumferentially distributed along the rotation axis of the rotating frame. Four sets of graphite plates with different curvatures are mounted on the four sets of graphite disks. The placement groove and the wiring groove are opened in the middle of the side of the four sets of graphite plates away from the laser rangefinder. The negative electrode detection probe is installed in each of the four sets of placement grooves. The negative electrode first connector is installed in each of the four sets of wiring grooves, and one end of each connector is connected to the four sets of negative electrode detection probes.

[0017] By adopting the above technical solution, when graphite plate switching is required, the fifth cylinder is activated. The extension end of the fifth cylinder moves, causing the third mounting frame to descend. The descent of the third mounting frame causes the rotating frame to descend, which in turn causes the graphite disk and graphite plate to descend. Then, the first drive motor is activated. The output end of the first drive motor rotates, causing the rotating frame to rotate. The rotation of the rotating frame causes the four sets of graphite disks to rotate. When the required graphite plate is switched to the upper end, the first drive motor is turned off, and the fifth cylinder is activated. The extension end of the fifth cylinder rises, causing the third mounting frame, the moving frame, the graphite disk, and the graphite plate to rise. When the graphite disk abuts against the mounting groove, the fifth cylinder is turned off, thereby realizing the switching of four sets of graphite plates with different curvatures, improving equipment utilization, enhancing production flexibility, and improving the overall efficiency of the production system.

[0018] Optionally, one end of the lifting platform is provided with a water supply pipe for supplying water to the graphite disk, and the end of the water supply pipe away from the graphite disk is connected to a water supply pump. The end of the lifting platform away from the water supply pipe is provided with a drain pipe for draining water from the graphite disk, and the end of the drain pipe away from the graphite disk is connected to a water pump.

[0019] By adopting the above technical solution, the water supply pipe driven by the water supply pump and the drainage pipe driven by the water pump can adjust the water supply flow and drainage flow according to the process requirements, thereby achieving precise and uniform forced cooling of the graphite disk and the aluminum profile in contact with it. This ensures that the aluminum profile quickly passes through the critical phase change temperature range, improves the mechanical properties and dimensional stability of the product, and the pumping function ensures that the cooling medium can be discharged in time after use, eliminating problems such as local temperature difference, water stains, or equipment corrosion caused by liquid accumulation.

[0020] Optionally, each of the four placement slots is equipped with a temperature sensor, and each is located on one side of the negative electrode detection probe.

[0021] By adopting the above technical solution, the temperature sensor monitors the temperature of the graphite plate in real time, ensuring that the cooling and shaping process of the aluminum profile is carried out at a suitable temperature, thus improving the cooling and shaping effect of the aluminum profile. Secondly, the temperature signal can provide feedback for the adjustment of the water supply and drainage system, realizing dynamic and intelligent adjustment of the cooling intensity, ensuring that the thermal management of the cooling and shaping process is in the optimal state. Finally, continuous temperature monitoring can also be used for early warning. When the temperature rises abnormally, it indicates that the graphite plate wear is aggravated or the cooling water circuit is blocked, thereby realizing preventive maintenance of the equipment and improving the reliability of the overall system and the stability of product quality.

[0022] Optionally, a second drive motor is provided on the side wall of the second mounting frame, and a rotating shaft is rotatably provided on the second mounting frame and passes through the second mounting frame. One end of the rotating shaft is fixedly connected to the output end of the second drive motor, and multiple sets of scrapers with different scraping curvatures are provided at intervals on the outer peripheral wall of the rotating shaft.

[0023] By adopting the above technical solution, the second drive motor is started, and the output end of the second drive motor rotates to drive the rotating shaft to rotate. The rotation of the rotating shaft drives multiple sets of scrapers with different scraping arcs to rotate, thereby realizing the switching of scrapers, enhancing the adaptability to different shaping needs and operational efficiency, and improving production continuity.

[0024] Optionally, each of the multiple sets of graphite disks has a locking groove at one end, a third drive motor is provided at the lower end of the lifting platform, a rotating groove is provided inside the lifting platform, a locking disk is rotatably arranged in the rotating groove, the locking disk is fixedly connected to the output end of the third drive motor, and rotates and abuts against the locking groove.

[0025] By adopting the above technical solution, the third drive motor is started, and the output end of the third drive motor rotates, causing the locking disc to rotate in the rotating groove and abut against the locking groove. The locking disc and the locking groove cooperate to lock the graphite disc, thereby preventing the graphite disc from moving during the cooling and shaping process and improving stability.

When the scraper descends to the appropriate height, the second cylinder is closed and the third cylinder is activated. The telescopic end of the third cylinder moves, causing the lower end of the second mounting frame to move. The movement of the second mounting frame causes the scraper to move, thereby scraping the curved surface of the graphite plate, improving scraping efficiency, extending the service life of a single graphite plate, reducing spare parts consumption and replacement frequency, and lowering overall production costs; 3.

Detailed Implementation

[0030] The present application will be further described in detail below with reference to Figures 1-4.

[0031] This application discloses an aluminum profile hot extrusion cooling and shaping device. Referring to Figures 1 and 2, the aluminum profile hot extrusion cooling and shaping device includes a fixed platform 1, a lifting platform 11 is installed at the upper end of the fixed platform 1, and an installation groove 12 is opened at the lower end of the lifting platform 11. A graphite disk 13 is installed in the installation groove 12. When the aluminum profile is cooled and shaped, the graphite disk 13 abuts against the installation groove 12 and does not move up or down. A graphite plate 14 is detachably installed at the middle of the inner bottom wall of the graphite disk 13. Multiple sets of fixing frames 15 are welded to the inner bottom wall of the graphite disk 13. A detection mechanism 2 and a scraping component 4 are installed on the lifting platform 11, and a switching component 5 is installed on the fixed platform 1.

[0032] When aluminum profiles need to be cooled and shaped, a graphite plate 14 with a suitable curvature is placed in a graphite disk 13 and fixed by a fixing frame 15. Then, the graphite disk 13 is raised into the mounting groove 12, and the height of the lifting platform 11 is adjusted at the same time to make the curved surface of the graphite plate 14 press against the aluminum profile, providing a precise forming surface. At the same time, the good thermal conductivity of graphite material is used to quickly absorb and dissipate the heat of the aluminum profile, so that it can be rapidly cooled, solidified and shaped under pressure, thereby ensuring that the aluminum profile obtains an accurate cross-sectional shape and stable dimensional accuracy. The detection mechanism 2 detects the thickness and curvature of the graphite plate 14 to ensure that the graphite plate 14 meets the requirements. The scraping component 4 scrapes the curved surface of the graphite plate 14 to repair or adjust the curved surface shape. The switching component 5 switches between different graphite plates 14 to improve production efficiency and adapt to different curved surface requirements. In this embodiment, four sets of fixing frames 15 are provided. The four sets of fixing frames 15 are located at the four corners of the graphite plate 14. Four sets are a preferred method in this embodiment, but other numbers of sets can also be used.

[0033] Referring to Figures 1, 2, and 4, the graphite plate 14 needs to undergo curvature and thickness testing within a specified period during its use. Therefore, the testing mechanism 2 in this embodiment includes a lifting frame 21, a first mounting frame 22, a first cylinder 23, a laser rangefinder 24, and a roughness testing component 3. The lifting frame 21 is lifted and mounted on the lifting platform 11. The first mounting frame 22 is slidably mounted on the lower end of the lifting frame 21. The first cylinder 23 is bolted to the side wall of the lifting frame 21, and its telescopic end is fixedly connected to the side wall of the first mounting frame 22. Multiple sets of laser rangefinders 24 are provided, and the multiple sets of laser rangefinders 24 are vertically fixedly mounted on the first mounting frame 22 at intervals. The middle set of laser rangefinders 24 is located directly above the highest point of the curvature surface of the graphite plate 14, and the other sets of laser rangefinders 24 are located on both sides of the highest point of the curvature surface of the graphite plate 14. The roughness testing component 3 is mounted on the first mounting frame 22.

[0034] When it is necessary to detect the curvature and thickness of the graphite plate 14, the first cylinder 23 is activated. The telescopic end of the first cylinder 23 moves, causing the first mounting frame 22 to move at the lower end of the lifting frame 21. The movement of the first mounting frame 22 causes multiple sets of laser rangefinders 24 to move. When the movement reaches the designated position, the first cylinder 23 is deactivated and the multiple sets of laser rangefinders 24 are activated simultaneously. The multiple sets of laser rangefinders 24 synchronously scan the curved surface of the graphite plate 14, thereby achieving high-precision and high-efficiency identification of the curvature of the graphite plate 14. Furthermore, by comparing the data from the two ends of the laser rangefinders 24 with the data from the highest point of the curved surface, the thickness of the graphite plate 14 can be accurately measured, realizing the detection of the curvature and thickness of the graphite plate 14. The quantitative monitoring of the wear of the graphite plate 14 means that when the curvature of the graphite plate 14 exceeds the allowable deviation, scraping is required; when the thickness of the graphite plate 14 approaches the minimum usable thickness, the graphite plate 14 needs to be switched. This transforms the entire maintenance process from periodic experience-based maintenance to condition-based predictive maintenance, ensuring that the graphite plate 14 is always in optimal working condition. While ensuring product quality consistency, it also optimizes the service life and replacement cycle of the mold, achieving a balance between production efficiency and cost control. In this embodiment, the laser rangefinder 24 is provided with five groups. Five groups are a preferred method in this embodiment, but other numbers of groups can also be used.

[0035] Referring to Figures 2 and 4, in order to detect the roughness of the curved surface of the graphite plate 14, the roughness detection component 3 in this embodiment includes an electric telescopic rod 31, a mounting plate 32, a positive electrode detection probe 33, a negative electrode detection probe 34, a negative electrode first connector 35, and a negative electrode second connector 36. The electric telescopic rod 31 is vertically bolted onto the first mounting frame 22, and the mounting plate 32 is welded to the telescopic end of the electric telescopic rod 31. Multiple sets of positive electrode detection probes 33 are provided, and the multiple sets of positive electrode detection probes 33 are vertically fixed at intervals. On the mounting plate 32, a placement groove 37 is provided in the middle of the side of the graphite plate 14 away from the laser rangefinder 24. The negative electrode detection probe 34 is fixedly installed in the placement groove 37. Both the graphite disk 13 and the lifting platform 11 are provided with wiring grooves 38. The negative electrode first connector 35 is fixedly installed in the wiring groove 38 of the graphite disk 13, and one end is connected to the negative electrode detection probe 34. The negative electrode second connector 36 is fixedly installed in the wiring groove 38 of the lifting platform 11, and is movably abutted against the end of the negative electrode first connector 35 away from the negative electrode detection probe 34.

[0036] When the surface roughness of the graphite plate 14 needs to be tested, the electric telescopic rod 31 is activated. The telescopic end of the electric telescopic rod 31 descends, causing the mounting plate 32 to descend. The descent of the mounting plate 32 causes multiple sets of positive electrode detection probes 33 to descend. When the positive electrode detection probes 33 elastically contact the surface of the graphite plate 14, the multiple sets of positive electrode detection probes 33 are energized sequentially. Combined with the negative electrode detection probes 34 pre-embedded in the graphite plate 14 and the movable contact of the first negative electrode connector 35 and the second negative electrode connector 36, a detection circuit is automatically formed. After energization, multiple sets of resistance values ​​are recorded sequentially. Since surface roughness directly affects the actual contact area, the difference in contact area will be converted into a change in contact resistance. By comparing the resistance change rate with standard data, the roughness level of the graphite plate 14 arc surface can be measured. Multi-point measurement ensures the comprehensiveness and representativeness of the evaluation, thereby realizing rapid, accurate and automated measurement of the roughness of the graphite plate 14 arc surface, improving the stability and repeatability of the detection, effectively preventing aluminum profile quality defects caused by excessive surface roughness, reducing equipment downtime and manual intervention, lowering maintenance costs, and enhancing the intelligent control of the production process and the consistency of product quality. In this embodiment, the positive electrode detection probe 33 is provided with three sets. Three sets are a preferred method in this embodiment, but other numbers of sets can also be used.

[0037] Referring to Figures 1 and 2, the curved surface of the graphite plate 14 may not be able to abut against the aluminum profile after a period of use. Therefore, the scraping assembly 4 in this embodiment includes a second cylinder 41, a second mounting frame 42, a third cylinder 43, a scraper 44, and a lifting component. The second cylinder 41 is vertically bolted to the upper end of the lifting platform 11, and its telescopic end is fixedly connected to the lifting frame 21. The second mounting frame 42 is slidably mounted on the lower end of the lifting frame 21 away from the first mounting frame 22. The third cylinder 43 is bolted to the side wall of the lifting frame 21 away from the second cylinder 41, and its telescopic end is fixedly connected to the second mounting frame 42. The scraper 44 is fixedly mounted on the second mounting frame 42, and the lifting component is mounted on the fixed platform 1.

[0038] When the curvature of the graphite plate 14 exceeds the allowable deviation or has defects, the second cylinder 41 is activated. The telescopic end of the second cylinder 41 descends, causing the lifting frame 21 to descend. The descent of the lifting frame 21 causes the second mounting frame 42 to descend, which in turn causes the scraper 44 to descend. When the scraper 44 descends to the appropriate height, the second cylinder 41 is deactivated and the third cylinder 43 is activated. The telescopic end of the third cylinder 43 moves, causing the second mounting frame 42 to move at the lower end of the lifting frame 21. The movement of the second mounting frame 42... The movable scraper 44 moves to scrape the curved surface of the graphite plate 14, thereby improving scraping efficiency, extending the service life of a single graphite plate 14, reducing spare parts consumption and replacement frequency, and lowering overall production costs. In this embodiment, two sets of second cylinders 41 are symmetrically arranged. The two sets of second cylinders 41 can improve the stability of the lifting frame 21 during its rise and fall, and also improve the accuracy of the detection of the curved surface of the graphite plate 14 and the accuracy of scraping the curved surface of the graphite plate 14, thereby improving the cooling and shaping effect of the aluminum profile.

[0039] Referring to Figures 1 and 2, the lifting component in this embodiment includes a fourth cylinder 45. Multiple sets of fourth cylinders 45 are provided, each set vertically bolted to the fixed platform 1, with its telescopic ends fixedly connected to the lower end of the lifting platform 11. After scraping the graphite plate 14, the fourth cylinder 45 is activated. The telescopic ends of the fourth cylinder 45 rise, causing the lifting platform 11 to rise. The rising of the lifting platform 11 then causes the graphite disk 13 and the graphite plate 14 to rise, thereby dynamically compensating for the thickness loss of the graphite plate 14 caused by the scraping repair. This continuously ensures the close contact required for cooling and shaping, ensuring constant contact heat conduction efficiency and the accuracy of profile contour forming. In this embodiment, four sets of fourth cylinders 45 are vertically arranged, with the telescopic ends of the four sets fixedly connected to the four corners of the lower end of the lifting platform 11. Four sets are a preferred embodiment, but other numbers of sets can also be used.

[0040] Referring to Figures 1, 2, and 3, in order to switch between multiple sets of graphite plates 14 with different curvatures, the switching component 5 in this embodiment includes a fifth cylinder 51, a third mounting frame 52, a first drive motor 53, and a rotating frame 54. The fifth cylinder 51 is vertically bolted to the inner bottom wall of the fixed platform 1. The third mounting frame 52 is fixedly mounted on the telescopic end of the fifth cylinder 51. The first drive motor 53 is bolted to the side wall of the third mounting frame 52. The rotating frame 54 is rotatably mounted on the third mounting frame 52. The output end of the first drive motor 53 is connected to the rotating frame 54. The moving frame 54 is fixedly connected. Four sets of graphite disks 13 are spaced apart on the rotating frame 54 and are distributed around the rotation axis of the rotating frame 54. Four sets of graphite plates 14 with different curvatures are detachably installed on the four sets of graphite disks 13. Each set of graphite plates 14 has a placement groove 37 and a wiring groove 38 at the center of the side away from the laser rangefinder 24. A negative electrode detection probe 34 is fixedly installed in each of the four placement grooves 37 and a negative electrode first connector 35 is fixedly installed in each of the four wiring grooves 38, and one end of each connector is connected to the four negative electrode detection probes 34.

[0041] When switching of graphite plate 14 is required, the fifth cylinder 51 is activated. The telescopic end of the fifth cylinder 51 moves, causing the third mounting frame 52 to descend. The descent of the third mounting frame 52 causes the rotating frame 54 to descend. The descent of the rotating frame 54 causes the graphite disk 13 and graphite plate 14 to descend. Then, the first drive motor 53 is activated. The output end of the first drive motor 53 rotates, causing the rotating frame 54 to rotate. The rotation of the rotating frame 54 causes the four sets of graphite disks 13 to rotate. When the required graphite plate 14 is switched to the upper end, the first drive motor 53 is turned off, and the fifth cylinder 51 is activated. The telescopic end of the fifth cylinder 51 rises, causing the third mounting frame 52, the moving frame, the graphite disk 13, and the graphite plate 14 to rise. When the graphite disk 13 abuts against the mounting groove 12, the fifth cylinder 51 is turned off. This achieves the switching of four sets of graphite plates 14 with different curvatures, improving equipment utilization, enhancing production flexibility, and improving the overall efficiency of the production system.

[0042] Referring to Figures 1 and 2, in this embodiment, a water supply pipe 6 is fixedly installed at one end of the lifting platform 11. A water supply pump is connected to the end of the water supply pipe 6 away from the graphite disk 13. A drain pipe 61 is fixedly installed at the end of the lifting platform 11 away from the water supply pipe 6. A water pump is connected to the end of the drain pipe 61 away from the graphite disk 13. The water supply pipe 6 driven by the water supply pump and the drain pipe 61 driven by the water pump can adjust the water supply flow and drainage flow according to process requirements, thereby achieving precise and uniform forced cooling of the graphite disk 13 and the aluminum profile in contact with it. This ensures that the aluminum profile quickly passes through the critical phase change temperature range, improves the mechanical properties and dimensional stability of the product, and the pumping function ensures that the cooling medium can be discharged in time after use, eliminating the problems of local temperature difference, water stain pollution or equipment corrosion caused by liquid accumulation.

[0043] Referring to Figure 4, in order to monitor the temperature of the graphite plate 14 in real time, temperature sensors 7 are fixedly installed in all four sets of placement slots 37 in this embodiment, and are all located on one side of the negative electrode detection probe 34. The temperature sensors 7 monitor the temperature of the graphite plate 14 in real time, ensuring that the cooling and shaping process of the aluminum profile is carried out at a suitable temperature, thereby improving the cooling and shaping effect of the aluminum profile. Secondly, the temperature signal can provide feedback for the adjustment of the water supply and drainage system, realize the dynamic and intelligent adjustment of the cooling intensity, and ensure that the thermal management of the cooling and shaping process is in the optimal state. Finally, continuous temperature monitoring can also be used for early warning. When the temperature rises abnormally, it indicates that the wear of the graphite plate 14 is aggravated or the cooling water circuit is blocked, thereby realizing preventive maintenance of the equipment and improving the reliability of the overall system and the stability of product quality.

[0044] Referring to Figures 1 and 2, in order to scrape the graphite plate 14 with different curvatures, a second drive motor 8 is bolted to the side wall of the second mounting frame 42 in this embodiment. A rotating shaft 81 is rotatably mounted on the second mounting frame 42 and extends through the second mounting frame 42. One end of the rotating shaft 81 is fixedly connected to the output end of the second drive motor 8. Multiple sets of scrapers 44 with different scraping curvatures are fixedly mounted at intervals on the outer peripheral wall of the rotating shaft 81. When the second drive motor 8 is started, the output end of the second drive motor 8 rotates, driving the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 drives the multiple sets of scrapers 44 with different scraping curvatures to rotate, thereby realizing the switching of scrapers 44, enhancing the adaptability to different shaping needs and operational efficiency, and improving production continuity.

[0045] Referring to Figure 3, in this embodiment, each of the multiple graphite disks 13 has a locking groove 91 at one end. A third drive motor 9 is bolted to the lower end of the lifting platform 11. A rotating groove 92 is provided inside the lifting platform 11. A locking disk 93 is rotatably installed in the rotating groove 92. The locking disk 93 is fixedly connected to the output end of the third drive motor 9 and rotates against the locking groove 91. When the third drive motor 9 is started, the output end of the third drive motor 9 rotates, causing the locking disk 93 to rotate in the rotating groove 92 and abut against the locking groove 91. The locking disk 93 and the locking groove 91 cooperate to lock the graphite disk 13, thereby preventing the graphite disk 13 from moving during the cooling and shaping process and improving stability.

[0046] The implementation principle of the aluminum profile hot extrusion cooling and shaping device in this application embodiment is as follows: A graphite plate 14 with a suitable curvature is placed in a graphite disk 13 and fixed by a fixing frame 15. Then, the graphite disk 13 is raised into the mounting groove 12, and the height of the lifting platform 11 is adjusted at the same time so that the curved surface of the graphite plate 14 is pressed against the aluminum profile, providing a precise forming surface. At the same time, the good thermal conductivity of graphite material is used to quickly absorb and dissipate the heat of the aluminum profile, so that it is rapidly cooled, solidified and shaped under pressure, thereby ensuring that the aluminum profile obtains an accurate cross-sectional shape and stable dimensional accuracy. The second cylinder 41 is activated, and the telescopic end of the second cylinder 41 descends, driving the lifting frame 21, the second mounting frame 42 and the scraper 44 to descend. When the scraper 44 descends to a suitable height, the third cylinder 43 is activated, and the telescopic end of the third cylinder 43 moves, driving the second mounting frame 42 and the scraper 44 to move, thereby realizing the shaping of the graphite plate 14. The arc surface of the graphite plate 14 is scraped, which improves scraping efficiency, extends the service life of a single graphite plate 14, and reduces the consumption and replacement frequency of spare parts. The fifth cylinder 51 is started, and the extension end of the fifth cylinder 51 moves to drive the third mounting frame 52, the rotating frame 54, the graphite disk 13 and the graphite plate 14 to descend. Then the first drive motor 53 is started, and the output end of the first drive motor 53 rotates to drive the rotating frame 54 and the four sets of graphite disks 13 to rotate. When the required graphite plate 14 is switched to the upper end, the first drive motor 53 is turned off and the fifth cylinder 51 is started. The extension end of the fifth cylinder 51 rises to drive the third mounting frame 52, the moving frame, the graphite disk 13 and the graphite plate 14 to rise. When the graphite disk 13 abuts against the mounting groove 12, the fifth cylinder 51 is turned off, thereby realizing the switching of four sets of graphite plates 14 with different arcs, improving equipment utilization, enhancing production flexibility and improving the overall efficiency of the production system.
