Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, and in particular to a high-speed extrusion aluminum alloy frame device and its processing method. Background Technology

[0002] In photovoltaic support structures, aluminum alloy frames are widely used due to their light weight, high strength and good corrosion resistance. Currently, the conventional processing method for such frame profiles is usually hot extrusion molding. A cylindrical aluminum rod is placed in an extrusion device, and then a hydraulic cylinder drives the extrusion shaft to apply a thrust to the aluminum rod, forcing the aluminum rod to be extruded from a specific forming channel of the extrusion die, and finally obtaining a continuous long strip frame profile with the same cross-sectional shape as the die.

[0003] Before entering the extrusion process, aluminum bars need to be heated to the required temperature by heating equipment and cut into billets of the corresponding length according to specifications. Then they are transferred into the extrusion equipment. However, during this transfer and loading process, because the temperature of the aluminum bars is much higher than the ambient temperature, their surface and the whole will quickly lose a lot of heat to the surrounding air, causing the die temperature to drop. The temperature drop not only makes the metal plasticity worse, but also increases the deformation resistance during extrusion, which in turn causes the extrusion pressure to rise and the fluidity to weaken, ultimately affecting the forming quality of the profile and the overall extrusion effect.

[0004] To address the aforementioned issues, this application proposes a high-speed extrusion aluminum alloy frame equipment and its processing method. Summary of the Invention

[0005] This invention proposes a high-speed extrusion aluminum alloy frame equipment and its processing method, which solves the problem in related technologies where, during the process of transferring heated aluminum bars to the extruder, the large temperature difference between the high-temperature bar and the environment leads to rapid heat dissipation on the surface and throughout the material, resulting in a drop in the die temperature. This reduces the plasticity of the metal, increases the deformation resistance, causes the extrusion pressure to rise, and reduces the fluidity, ultimately affecting the profile forming quality and extrusion effect.

[0006] The present invention proposes a high-speed extrusion aluminum alloy frame device, comprising a device support, a lifting bearing component, a pressing component, and a driving component;

[0007] An extrusion mold is installed at one end of the equipment support, the lifting support is installed in the middle of the equipment support for supporting the workpiece, and the pushing component is installed at the other end of the equipment support for pushing the workpiece on the lifting support to be extruded from the extrusion mold.

[0008] The equipment support is equipped with a heating box located above the lifting support component. The heating box contains a hollow cylinder, which is driven to rotate by a driving component. An arc-shaped groove is provided on the outer periphery of the hollow cylinder. A hopper communicating with the interior of the heating box and accommodating the workpiece is installed on the top of the heating box, and a discharge port is provided at the bottom.

[0009] A blower connected to the hollow cylinder is installed on one side of the hopper, and an exhaust fan is installed on the other side of the hopper. A heating fan is installed on the heating box to deliver hot air into the hollow cylinder. The hot air is blown into the hopper by the blower to blow the workpiece and is discharged through the exhaust fan.

[0010] As a further optimization of the present invention, the heating air component includes a rotary joint and a hot air pipe. Loading holes are provided at both ends of the heating box. Shaft tubes are connected to both ends of the hollow cylinder. The two shaft tubes are rotatably engaged with the two loading holes respectively. The shaft tube at one end extends out of the loading hole at one end of the heating box. The blower is connected to the loading hole at the other end of the heating box. The rotary joint is installed at one end of the heating box, and the rotating air outlet end of the rotary joint is connected to the shaft tube at one end. The hot air pipe is connected to the air inlet end of the rotary joint and is used to connect to a hot air blower.

[0011] As a further optimization of the present invention, the driving component includes a motor, a driving gear and a driven gear. The driven gear is fixedly mounted on a shaft tube at one end. The motor is installed at one end of the heating box, and the output end of the motor is connected to the driving gear that meshes with the driven gear.

[0012] As a further optimization of the present invention, the blowing component includes a blowing pipe, which is installed on one side of the hopper and arranged vertically. A plurality of blowing holes communicating with the inside of the hopper are opened on one side of the blowing pipe along its length. A guide pipe is connected to the other side of the blowing pipe, and the guide pipe is connected to the loading hole at the other end of the heating box. The hot air flowing in the hollow cylinder enters the guide pipe through the shaft tube at the other end.

[0013] As a further optimization of the present invention, the exhaust component includes an exhaust hood, which is installed on the other side of the hopper. One side of the exhaust hood has an opening that communicates with the inside of the hopper, and the other side is connected to an exhaust pipe, which is used to connect to an exhaust device.

[0014] As a further optimization of the present invention, the lifting support includes a cylinder and a support seat. The support seat is located in the middle of the equipment support and below the heating box. The bottom of the support seat is connected to the cylinder, and the support seat is driven by the cylinder to move up and down. A semi-circular groove for placing the workpiece is provided on the support seat.

[0015] As a further optimization of the present invention, the extrusion die is provided with a forming channel for extruding and forming the workpiece.

[0016] As a further optimization of the present invention, the pressing component includes a hydraulic cylinder, which is installed at the other end of the equipment support, and the driving end of the hydraulic cylinder is connected to a pusher head, which is driven by the hydraulic cylinder to push the workpiece out of the forming channel.

[0017] A method for processing aluminum alloy frames by high-speed extrusion, using the aforementioned high-speed extrusion aluminum alloy frame equipment, includes the following steps:

[0018] Step 1: Hot air is delivered into the hollow cylinder through the heating air supply component, blown into the hopper through the blower component, and then discharged through the exhaust component.

[0019] Step 2: Place the aluminum rod workpieces into the hopper one by one and stack them. The bottom layer of aluminum rod workpieces falls into the arc groove on the hollow cylinder to achieve heating.

[0020] Step 3: Raise the lifting support to the bottom of the heating box. The drive unit drives the hollow cylinder to rotate the aluminum rod workpiece in the arc groove to correspond with the material discharge port at the bottom of the heating box. The aluminum rod falls onto the lifting support through the material discharge port. The lifting support drives the aluminum rod down to correspond with the extrusion die.

[0021] Step 4: The pushing component pushes the aluminum rod workpiece on the lifting support component into the extrusion die, where it is extruded and shaped.

[0022] Step 5: Continue to raise the lifting support to the bottom of the heating box, and the drive unit will drive the hollow cylinder to continue rotating. Repeat the above actions.

[0023] The above-described technical solution of the present invention has the following beneficial technical effects:

[0024] 1. The aluminum rod workpiece is heated by blowing hot air onto its surface using a blower, while the hot air passing through the hollow cylinder heats the aluminum rod workpiece in the arc groove through contact heat transfer. Combined with the heat preservation field formed in the heating box, multi-stage heat preservation heating of the aluminum rod workpiece is achieved during the transfer and loading process. This effectively suppresses heat loss from the aluminum rod surface and the whole to the surrounding air, keeping the aluminum rod temperature within the required range for the process. This ensures good plasticity of the metal, reduces deformation resistance, and improves the forming quality and overall extrusion effect of the profile. At the same time, the exhaust fan removes blown debris in a timely manner, preventing impurities from entering the extrusion process and further improving the finished product qualification rate.

[0025] 2. After one of the aluminum rods is extruded, the lifting support is raised to the bottom of the heating box, and the drive unit drives the hollow cylinder to continue rotating. This process is repeated to achieve rapid and automatic loading and unloading of the aluminum rods, improving the efficiency of the extrusion operation. Meanwhile, while waiting for extrusion, the stacked aluminum rods are continuously heated and kept warm by the hot air in the hopper, effectively preventing heat loss caused by prolonged static placement. This ensures that each aluminum rod maintains a stable process temperature before entering the extrusion die, thereby maintaining the continuity of the extrusion process and further ensuring the consistency of the profile forming quality.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0035] like Figure 1-7 As shown, the present invention proposes a high-speed extrusion aluminum alloy frame device, which includes a device support 1, a lifting bearing 2, a pushing component 3 and a driving component 6.

[0036] An extrusion die 101 is installed at one end of the equipment support 1, a lifting bearing 2 is installed in the middle of the equipment support 1 for bearing the workpiece, and a pushing component 3 is installed at the other end of the equipment support 1 for pushing the workpiece on the lifting bearing 2 to be extruded from the extrusion die 101.

[0037] A heating box 4 is installed on the equipment support 1 above the lifting support 2. A hollow cylinder 5 is installed inside the heating box 4 and is driven to rotate by the driving component 6. An arc groove 51 is opened on the outer periphery of the hollow cylinder 5. A hopper 41 that communicates with the inside of the heating box 4 and accommodates the workpiece is installed on the top of the heating box 4, and a discharge port 42 is opened at the bottom.

[0038] A blower 8 connected to the hollow cylinder 5 is installed on one side of the hopper 41, and an exhaust fan 9 is installed on the other side of the hopper 41. A heating air supply 7 is installed on the heating box 4 to deliver hot air into the hollow cylinder 5. The hot air is blown into the hopper 41 by the blower 8 to blow the workpiece and is discharged through the exhaust fan 9.

[0039] Hot air is delivered into the hollow cylinder 5 via the heating air supply component 7 and blown into the discharge hopper 41 via the blower component 8. The air is then discharged via the exhaust component 9. Aluminum rods are then stacked in the discharge hopper 41. During this process, hot air blows across the surface of the aluminum rods, providing insulation and heating. Debris blown off the aluminum rods is promptly discharged via the exhaust component 9. The bottom layer of aluminum rods falls into the arc-shaped groove 51 on the hollow cylinder 5. Because of the hot air passing through the hollow cylinder 5, heat is transferred to the aluminum rods for further heating. An insulation field is also formed within the heating chamber 4 to increase the subsequent extrusion speed. The lifting support component 2 is then raised to the bottom of the heating chamber 4. The drive component 6 drives the hollow cylinder 5 to rotate the aluminum rods in the arc-shaped groove 51 until they align with the discharge port 42 at the bottom of the heating chamber 4. The aluminum rods then fall onto the lifting support component through the discharge port 42. 2. The lifting support 2 lowers the aluminum rod to correspond with the extrusion die 101. Then, the pushing component 3 pushes the aluminum rod on the lifting support 2 into the extrusion die 101 and is extruded into shape. The above design uses the blowing component 8 to blow hot air to keep the surface of the aluminum rod workpiece warm. At the same time, the hot air passing through the hollow cylinder 5 is used to conduct contact heat transfer heating on the aluminum rod workpiece in the arc groove 51. Combined with the heat preservation field formed in the heating box 4, the multi-stage heat preservation heating of the aluminum rod workpiece is realized during the transfer and loading process. This effectively suppresses the heat loss of the aluminum rod surface and the whole to the surrounding air, keeps the temperature of the aluminum rod entering the die within the range required by the process, thereby ensuring the good plasticity of the metal, reducing the deformation resistance, and thus improving the forming quality of the profile and the overall extrusion effect. At the same time, the exhaust component 9 removes the blown debris in time to prevent impurities from entering the extrusion process and further improve the finished product qualification rate.

[0040] After one of the aluminum rods is extruded, the lifting support 2 is raised to the bottom of the heating box 4, and the driving component 6 drives the hollow cylinder 5 to continue rotating. By repeating the above actions, the subsequent aluminum rods can be processed. This achieves a rapid and automatic loading and unloading cycle for the aluminum rods, improving the efficiency of the extrusion operation. At the same time, while waiting for extrusion, the stacked aluminum rods are continuously heated and kept warm by the hot air in the hopper 41. This effectively prevents the aluminum rods from losing heat due to prolonged static placement, ensuring that each aluminum rod can maintain a stable process temperature before entering the extrusion die 101. This maintains the continuity of the extrusion process and further ensures the consistency of the profile forming quality.

[0041] In this embodiment, the heating air component 7 includes a rotary joint 71 and a hot air pipe 72. Loading holes are provided at both ends of the heating box 4. Shaft tubes 52 are connected to both ends of the hollow cylinder 5. The two shaft tubes 52 are rotatably engaged with the two loading holes respectively. The shaft tube 52 at one end extends out of the loading hole at one end of the heating box 4. The blower 8 is connected to the loading hole at the other end of the heating box 4. The rotary joint 71 is installed at one end of the heating box 4, and the rotating air outlet end of the rotary joint 71 is connected to the shaft tube 52 at one end. The hot air pipe 72 is connected to the air inlet end of the rotary joint 71, and the hot air pipe 72 is used to connect to the hot air blower.

[0042] Hot air duct 72 is connected to an external hot air blower. Hot air enters the air inlet of rotary joint 71 through hot air duct 72, and is then delivered from the rotating air outlet of rotary joint 71 to the interior of hollow cylinder 5 connected to one end of shaft tube 52. Subsequently, hot air flows out through shaft tube 52 at the other end of hollow cylinder 5 and is fed into hopper 41 by blower 8, thereby blowing hot air onto the aluminum rod workpiece in hopper 41. At the same time, the hot air fully exchanges heat with the cylinder wall when passing through the inner cavity of hollow cylinder 5, raising the cylinder wall temperature and providing a heat source for subsequent contact conduction heating of aluminum rod in arc groove 51, thus realizing the utilization and directional delivery of hot air.

[0043] In this embodiment, the driving component 6 includes a motor 61, a driving gear 62 and a driven gear 63. The driven gear 63 is fixedly mounted on a shaft tube 52 at one end. The motor 61 is mounted at one end of the heating box 4. The output end of the motor 61 is connected to the driving gear 62 that meshes with the driven gear 63.

[0044] During operation, the motor 61 drives the drive gear 62 to rotate the driven gear 63. The driven gear 63 drives the shaft tube 52 and the hollow cylinder 5 connected to it to rotate inside the heating box 4. By controlling the rotation speed of the motor 61, the arc groove 51 on the outer circumference of the hollow cylinder 5 can be rotated sequentially to the receiving position corresponding to the discharge hopper 41, and to the unloading position corresponding to the discharge port 42 at the bottom of the heating box 4, so as to realize the automatic loading and unloading of aluminum rod workpieces.

[0045] In this embodiment, the blower 8 includes a blower pipe 81, which is installed on one side of the hopper 41 and arranged vertically. A plurality of blower holes 83 communicating with the inside of the hopper 41 are opened on one side of the blower pipe 81 along its length direction. The other side of the blower pipe 81 is connected to a guide pipe 82, and the guide pipe 82 is connected to the loading hole at the other end of the heating box 4. The hot air flowing in the hollow cylinder 5 enters the guide pipe 82 through the shaft tube 52 at the other end.

[0046] Hot air flowing out from the shaft tube 52 at the other end of the hollow cylinder 5 is guided into the blowing pipe 81 through the air guide pipe 82. The blowing holes 83 on the blowing pipe 81 are directly facing the inside of the hopper 41. Therefore, the hot air will be blown out from the blowing holes 83 and sweep across the surface of the aluminum rods stacked in the hopper 41. This porous vertically arranged blowing structure allows the hot air to cover aluminum rods at different heights and blow on the surface of each aluminum rod. On the one hand, the heat is transferred to the aluminum rods through forced convection, which plays a role in heat preservation or auxiliary heating and prevents the aluminum rods from cooling down during the waiting period. On the other hand, the high-speed airflow can blow away the oxide scale, debris and other impurities that adhere to the surface of the aluminum rods during heating or handling. With the cooperation of the exhaust fan 9 on the opposite side, the dust-laden airflow is discharged, thereby ensuring the cleanliness of the aluminum rod surface and preventing impurities from entering the extrusion die 101 with the aluminum rods and affecting the quality of the frame profile.

[0047] In this embodiment, the exhaust component 9 includes an exhaust hood 91, which is installed on the other side of the hopper 41. One side of the exhaust hood 91 has an opening that communicates with the inside of the hopper 41, and the other side is connected to an exhaust pipe 92, which is used to connect to an exhaust device.

[0048] When the blower 8 blows hot air into the hopper 41, the hot air carries the debris and excess heat peeled off from the surface of the aluminum rod. Under negative pressure, it is drawn in by the opening of the exhaust hood 91 and discharged to the external collection system through the exhaust pipe 92.

[0049] It should be noted that the air extraction device in this embodiment can be a chip extraction pump.

[0050] In this embodiment, the lifting support 2 includes a cylinder 21 and a support seat 22. The support seat 22 is located in the middle of the equipment support 1 and below the heating box 4. The bottom of the support seat 22 is connected to the cylinder 21, and the support seat 22 is driven by the cylinder 21 to move up and down. A semi-circular groove for placing workpieces is provided on the support seat 22.

[0051] The cylinder 21 is used to drive the support seat 22 to move up and down. When the support seat 22 rises to the highest position, its top is close to the bottom of the heating box 4 and located directly below the discharge port 42. It is used to receive the heated aluminum rod workpiece falling from the discharge port 42. The semi-circular groove opened on the support seat 22 is adapted to the cylindrical shape of the aluminum rod, so that the aluminum rod can sit in it. When the aluminum rod falls onto the support seat 22, the cylinder 21 drives the support seat 22 to descend to a position coaxially aligned with the entrance of the extrusion die 101. At this time, the pusher 3 can push the aluminum rod axially to enter the extrusion die 101 for extrusion molding.

[0052] In this embodiment, the extrusion die 101 is provided with a forming channel 102 for extruding and forming the workpiece;

[0053] When the pusher 3 pushes the heated aluminum rod into the extrusion die 101, the aluminum rod is forced into the forming channel 102 inside the extrusion die 101 under the action of axial thrust. The cross-sectional shape of the forming channel 102 is consistent with the cross-sectional profile of the required aluminum alloy frame. When the aluminum rod passes through the forming channel 102, it is constrained by the channel wall and plastically deformed, gradually changing from a cylindrical blank into a continuous long strip profile with the same cross-sectional shape as the forming channel 102, and is extruded from the outlet end of the extrusion die 101.

[0054] In this embodiment, the pressing component 3 includes a hydraulic cylinder 31, which is installed at the other end of the equipment support 1. The driving end of the hydraulic cylinder 31 is connected to a push head 32, which is driven by the hydraulic cylinder 31 to push the workpiece out of the forming channel 102.

[0055] During operation, the hydraulic cylinder 31 drives the pusher head 32 to move forward. The pusher head 32 pushes the aluminum rod workpiece on the bearing seat 22 forward along its axial direction, so that the front end of the aluminum rod enters the forming channel 102 of the extrusion die 101, forcing the aluminum rod to pass through the forming channel 102 and finally be continuously extruded from the outlet of the extrusion die 101.

[0056] A method for processing aluminum alloy frames by high-speed extrusion, using the aforementioned high-speed extrusion aluminum alloy frame equipment, includes the following steps:

[0057] Step 1: Hot air is delivered to the hollow cylinder 5 through the heating air supply component 7, and blown into the material hopper 41 through the blower component 8, and then discharged through the exhaust component 9.

[0058] Step 2: Place the aluminum rod workpieces into the hopper 41 one by one and stack them. The bottom aluminum rod workpieces fall into the arc groove 51 on the hollow cylinder 5 to achieve heating.

[0059] Step 3: Raise the lifting support 2 to the bottom of the heating box 4. Drive the hollow cylinder 5 to rotate the aluminum rod workpiece in the arc groove 51 to correspond with the material discharge port 42 at the bottom of the heating box 4. The aluminum rod falls onto the lifting support 2 through the material discharge port 42. The lifting support 2 drives the aluminum rod down to correspond with the extrusion die 101.

[0060] Step 4: The pushing component 3 pushes the aluminum rod workpiece on the lifting support component 2 into the extrusion die 101, where it is extruded and shaped.

[0061] Step 5: Continue to raise the lifting support 2 to the bottom of the heating box 4, and drive the hollow cylinder 5 to continue rotating, repeating the above actions.

[0062] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
