Description

Technical Field

[0001] This invention relates to the field of aluminum extrusion radiator processing technology, and more particularly to an aluminum extrusion radiator substrate extrusion processing apparatus. Background Technology

[0002] Aluminum extruded heat sink substrates are heat dissipation structural components made from aluminum alloy through a one-time hot extrusion process. They have advantages such as excellent thermal conductivity, light weight, and high forming efficiency, and are widely used in new energy vehicles, power electronics, communication equipment, photovoltaic inverters, and industrial automation equipment. Aluminum extruded heat sink substrates typically have a large number of closely spaced heat dissipation teeth to increase the heat dissipation area and improve heat exchange efficiency. The production process generally requires sequential extrusion molding, quenching and cooling, traction stretching, and drying to ensure the product's mechanical properties, dimensional accuracy, and surface quality.

[0003] However, existing aluminum extruded radiator substrates are typically continuously stretched by a traction device after quenching. Due to the different cooling and shrinkage rates of the heat dissipation teeth and the base plate, large internal stresses are easily generated inside the profile. Traditional traction methods only clamp the sides of the substrate, lacking support and restraint for the inside of the heat dissipation teeth. Twisting and displacement are prone to occur during traction, affecting the dimensional accuracy of the product. At the same time, residual water mist after quenching easily adheres to the surface of the heat dissipation teeth and the inside of the tooth grooves, which not only reduces the frictional stability during traction, leading to slippage, inconsistent stretching, and dimensional deviations, but also causes surface corrosion, dark spots, and other defects due to long-term retention of residual water stains, affecting the appearance quality, corrosion resistance, and heat dissipation performance of the radiator substrate. Therefore, it is necessary to propose a stable conveying device for aluminum extruded radiator substrates after extrusion to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems existing in the prior art, and to propose an aluminum extrusion heat sink substrate extrusion processing apparatus.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum extrusion heat sink substrate extrusion processing device, including an extruder, a conveying base is placed on one side of the output end of the extruder, a mist cooling mechanism is provided on both sides of the conveying base near the extruder, and a displacement mechanism is installed on both sides of the conveying base away from the extruder. A rotatable first mounting housing is installed on the working end of the displacement mechanism, and a fifth electric telescopic rod is fixedly connected to the top of the first mounting housing through a special-shaped rod. A horizontally arranged silicone plate is fixedly connected to the telescopic end of the fifth electric telescopic rod. A second mounting housing is fixedly installed on the side of the first mounting housing near the extruder. Several second mounting blocks are installed inside the second mounting housing through a limiting mechanism. A T-shaped silicone plate is fixedly connected to the front end of the second mounting block. The conveying base is provided with two sets of mounting brackets at the upper end away from the extruder. The lower end of the front mounting bracket is provided with a first limiting mechanism, and a movable second limiting mechanism is installed between the two sets of mounting brackets. The conveying base has a support mechanism inside at the end away from the extruder, which is used to support the inclined heat sink substrate.

[0006] Preferably, the mist cooling mechanism includes a water tank, and the output end of the water tank is connected to a plurality of mist cooling nozzles, which are used to spray soft water onto the radiator substrate to complete the mist cooling quenching.

[0007] Preferably, the displacement mechanism includes a second lead screw mounted on the side of the transmission base, a first sliding block mounted on the moving end of the second lead screw, a third electric telescopic rod fixedly mounted on the top end of the first sliding block, a first mounting block fixedly mounted on the telescopic end of the third electric telescopic rod, and the first mounting housing located between the two first mounting blocks and driven to rotate by a first motor mounted on the first mounting blocks.

[0008] Preferably, the limiting mechanism includes spring telescopic rods installed on the upper and lower sides inside the second mounting housing. The telescopic ends of the spring telescopic rods are equipped with pressing rods. A plurality of second mounting blocks are placed between two pressing rods. Both the upper and lower ends of the second mounting blocks are provided with mounting grooves that cooperate with the pressing rods. A first electromagnet is installed inside the second mounting housing. The rear end of the second mounting block is provided with a magnetic block that cooperates with the first electromagnet.

[0009] Preferably, both sides of the T-shaped silicone sheet are provided with flame-retardant and water-absorbing cloth, and a cavity is opened inside the T-shaped silicone sheet. A sponge block is slidably installed inside the cavity, and a silicone mounting block is installed at one end of the sponge block outside the cavity. The silicone mounting block has a through groove running vertically through it.

[0010] Preferably, the first limiting mechanism includes a first electric telescopic rod rotatably mounted on the lower end of the front mounting bracket. An L-shaped mounting plate is fixedly connected to the telescopic end of the first electric telescopic rod. The L-shaped mounting plate is inverted and an L-shaped mounting block is fixedly connected to the lower end of the L-shaped mounting plate. The L-shaped mounting block has a drainage groove that runs through the front and back.

[0011] Preferably, the second limiting mechanism includes a first lead screw installed between two sets of mounting brackets. A second sliding block is installed at the moving end of the first lead screw. A second electric telescopic rod is installed at the lower end of the second sliding block through a rotating connector. A second electromagnet is fixedly installed at the telescopic end of the second electric telescopic rod. Several magnetic rods are magnetically attracted below the second electromagnet. The outer diameter of the magnetic rods is adapted to the inner diameter of the through groove inside the silicone mounting block.

[0012] Preferably, the support mechanism includes two sets of sixth electric telescopic rods installed inside the conveyor base. The telescopic end of the front sixth electric telescopic rod is rotatably mounted with a second mounting plate via a U-shaped mounting block, and the telescopic end of the rear sixth electric telescopic rod is rotatably mounted with a first mounting plate via a U-shaped mounting block. A first protrusion is mounted on the top of the first mounting plate, and an insertion groove that mates with the first protrusion is provided on the bottom wall of the first mounting housing. A second protrusion is mounted on the top of the second mounting plate.

[0013] Preferably, the conveying base has an inclined guide groove inside, and the end of the guide groove has a water outlet.

[0014] Preferably, a first fan and a second fan are arranged in sequence behind the water tank. The first fan blows out low-pressure, room-temperature, dry air, and the second fan blows out high-pressure, cold air. Both of them act on the surface of the radiator substrate.

[0015] Compared with existing technologies, the advantages of this invention are: 1. After the heat sink substrate is extruded, the present invention uses a mist cooling nozzle for continuous mist cooling quenching, and uses first limiting rollers with adjustable spacing on both sides to guide and limit the profile. While ensuring uniform cooling, it effectively suppresses the left and right swing and torsional deformation of the profile. It can be adapted to heat sink substrates of different widths, and ensures that the extruded profile always maintains a stable conveying state. It provides a reliable posture basis for subsequent clamping, cooling and drying processes, and improves the consistency of product size and the stability of continuous production.

[0016] 2. This invention constructs an internal and external combined clamping structure through a second limiting roller, a silicone plate, and a T-shaped silicone plate. The T-shaped silicone plate penetrates deep into the heat dissipation tooth groove to form internal elastic support, while external clamping is simultaneously implemented from above and to the side. This ensures that the heat sink substrate is reliably restricted in all directions during the conveying process. At the same time, the flame-retardant absorbent cloth has the functions of absorbing water, increasing friction, and providing cushioning protection, which can prevent the heat dissipation teeth from being indented, deformed, scratched, or slipped during the clamping process, thus greatly improving the conveying stability and the quality of the finished product.

[0017] 3. This invention adopts a replaceable T-shaped silicone plate structure. Through the pre-limiting of the extrusion rod and the electromagnetic adsorption locking, the T-shaped silicone plate can be quickly disassembled and finely adjusted in position. Different specifications of heat sink base plates can be adapted by simply replacing the T-shaped silicone plate of the corresponding size. It can also be accurately calibrated according to the position of the tooth groove, which not only shortens the downtime for changing models, but also avoids the parts falling off or shifting during the adjustment process. At the same time, it supports independent replacement after a single piece is damaged, reducing maintenance costs and improving the versatility of the equipment and production efficiency.

[0018] 4. This invention adopts a staged drying method. First, a first fan outputs low-pressure, room-temperature air to remove water accumulated over a large area on the surface, allowing the temperature of the radiator substrate to drop gradually and avoiding thermal shock caused by sudden cooling. Then, a second fan outputs high-pressure cold air for deep drying and rapid cooling. This not only improves the overall drying efficiency but also effectively reduces the risk of deformation of the profile due to excessive temperature difference, resulting in a more uniform and stable cooling effect for the radiator substrate and improving product quality stability.

[0019] 5. The present invention is equipped with a flip-up flow guiding mechanism, which simultaneously lifts and tilts the heat sink base plate during the blowing process, so that the water accumulated inside the heat sink grooves flows quickly along the grooves to the end under the action of gravity, and is discharged in a concentrated manner through the flow guiding structure. This effectively solves the problem that traditional blowing methods are difficult to remove deep groove water, while avoiding wastewater dripping everywhere and causing equipment pollution and water accumulation. It achieves efficient discharge of water accumulated inside the heat sink base plate, improves the subsequent drying effect and the cleanliness of the production environment.

[0020] 6. After the accumulated water is drained, the invention drives the silicone mounting block to move via a magnetic rod, causing the sponge block to slide synchronously along the inside of the heat dissipation groove. This allows for comprehensive absorption and removal of water from the inner wall, corners, and gaps of the groove, which are difficult to reach by air blowing. This further removes residual trace water stains, preventing long-term residual water from causing oxidation, corrosion, and spot defects on the aluminum profile surface. It also improves the corrosion resistance, appearance quality, and service life of the radiator substrate, while further ensuring the quality of the product upon leaving the factory.

[0021] In summary, this invention optimizes the entire process of conveying, clamping, changing, cooling, draining, and dewatering of the radiator substrate after extrusion. Through the coordinated use of multi-level limiting support, rapid changing mechanism, staged cooling and drying, gravity-guided drainage, and deep sponge water absorption, it not only improves the stability of conveying and production efficiency, but also effectively reduces the risks of product deformation, scratches, water accumulation, and corrosion.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1 to 12An aluminum extrusion radiator substrate extrusion processing device includes an extruder 1. The extruder 1 is existing technology, and its specific structural design will not be described in detail here. A conveyor base 3 is placed on one side of the output end of the extruder 1. A transmission roller 17 is laid on the top of the conveyor base 3. The transmission roller 17 is used to convey the radiator substrate 2 produced by the extruder 1. A fourth electric telescopic rod 22 is fixedly installed on both sides of the discharge port of the extruder 1. A first limiting roller 15 is fixedly connected to the telescopic end of the fourth electric telescopic rod 22. The first limiting roller 15 is designed vertically and limits the radiator substrate 2 from both sides to prevent the radiator substrate 2 from twisting left and right and to correct its twisting trend. Water tanks 4 are provided on both sides of the conveyor base 3 near the extruder 1. Several mist cooling nozzles 5 are connected to the output end of the water tank 4. The mist cooling nozzles 5 are used to spray soft water on the radiator substrate 2 to complete the mist cooling quenching.

[0026] A second lead screw 13 is installed on both sides of the conveyor base 3 away from the extruder 1. A first sliding block 18 is installed on the moving end of the second lead screw 13. A third electric telescopic rod 19 is fixedly installed on the top of the first sliding block 18. A first mounting block 14 is fixedly installed on the telescopic end of the third electric telescopic rod 19. A first mounting housing 21 located above the conveyor base 3 is provided between the two first mounting blocks 14. The first mounting housing 21 is driven to rotate by a first motor 20 installed on the first mounting block 14. A second motor 33 is fixedly installed on both the left and right sides of the first mounting housing 21. A second limiting roller 46 is installed on the output end of the second motor 33 through a connecting rod. The second limiting roller 46 is used to center the radiator base plate 2. A fifth electric telescopic rod 25 is fixedly connected to the top of the first mounting housing 21 through a special-shaped rod. A horizontally arranged silicone plate 26 is fixedly connected to the telescopic end of the fifth electric telescopic rod 25. The vertical height of the silicone plate 26 can be adjusted by the fifth electric telescopic rod 25.

[0027] A second mounting housing 23 is fixedly mounted on the side of the first mounting housing 21 near the extruder 1. Spring telescopic rods 29 are installed on both the upper and lower sides of the interior of the second mounting housing 23. Extrusion rods 28 are installed at the telescopic ends of the spring telescopic rods 29. The spring telescopic rods 29 can adjust the distance between the upper and lower extrusion rods 28. Several second mounting blocks 30 are placed between the two extrusion rods 28. Both the upper and lower ends of the second mounting blocks 30 are provided with mounting grooves that mate with the extrusion rods 28, allowing the extrusion rods 28 to extend from the upper part of the second mounting blocks 30. The lower two ends are limited. The first electromagnet 27 is installed inside the second mounting housing 23. The rear end of the second mounting block 30 is provided with a magnetic block 31 that cooperates with the first electromagnet 27. The front end of the second mounting block 30 is fixedly connected to a T-shaped silicone plate 44. Both sides of the T-shaped silicone plate 44 are provided with flame-retardant and water-absorbing cloth 24. The T-shaped silicone plate 44 has a cavity inside. A sponge block 45 is slidably installed inside the cavity. A silicone mounting block 32 is installed at one end of the sponge block 45 outside the cavity. The silicone mounting block 32 has a through groove running vertically inside.

[0028] Two sets of mounting brackets 8 are provided above the end of the conveyor base 3 away from the extruder 1. The lower end of the front mounting bracket 8 is equipped with a first electric telescopic rod 10 through a rotating connector. The telescopic end of the first electric telescopic rod 10 is fixedly connected to an L-shaped mounting plate 37. The L-shaped mounting plate 37 is inverted and the lower end of the L-shaped mounting plate 37 is fixedly connected to an L-shaped mounting block 38. The L-shaped mounting block 38 has a drainage groove that runs through the front and back. A first lead screw 9 is installed between the two sets of mounting brackets 8. A second sliding block 36 is installed at the moving end of the first lead screw 9. The lower end of the second sliding block 36 is equipped with a second electric telescopic rod 11 through a rotating connector. A second electromagnet 34 is fixedly installed at the telescopic end of the second electric telescopic rod 11. Several magnetic rods 35 are magnetically attracted below the second electromagnet 34. The outer diameter of the magnetic rods 35 is adapted to the inner diameter of the through groove inside the silicone mounting block 32, so that the magnetic rods 35 can be inserted into the corresponding through groove.

[0029] Behind the water tank 4, there are a first fan 6 and a second fan 7. Both the first fan 6 and the second fan 7 are existing technologies, and their specific structural design will not be described in detail here. The first fan 6 blows out low-pressure, room-temperature dry air to gently blow away the floating water on the surface of the radiator substrate 2, and the second fan 7 blows out high-pressure cold air to deeply cool and dry the radiator substrate 2.

[0030] Below each of the two sets of mounting brackets 8, there is a sixth electric telescopic rod 40 installed inside the conveyor base 3. The telescopic end of the front sixth electric telescopic rod 40 is rotatably mounted with a second mounting plate 41 via a U-shaped mounting block 43. The telescopic end of the rear sixth electric telescopic rod 40 is rotatably mounted with a first mounting plate 16 via a U-shaped mounting block 43. A first protrusion 39 is installed at the top of the first mounting plate 16. An insertion groove that mates with the first protrusion 39 is opened on the bottom wall of the first mounting housing 21. A second protrusion 42 is installed at the top of the second mounting plate 41.

[0031] The conveyor base 3 has an inclined guide channel inside, and the end of the guide channel has a water outlet 12.

[0032] In use, the heated and heat-insulated aluminum rod is fed into the extruder 1. Under the extrusion pressure, the metal is uniformly formed through the die. The extruded radiator substrate 2 is continuously conveyed by the transmission roller 17 and simultaneously sprayed with soft water by the mist cooling nozzle 5 to complete the mist cooling quenching. First limiting rollers 15 are installed on both sides of the discharge port to prevent the radiator substrate from twisting left and right and to correct its twisting tendency. The fourth electric telescopic rod 22 can adjust the distance between the first limiting rollers 15 on both sides, thereby adapting to radiator substrates 2 of different sizes.

[0033] After sufficient fog cooling, the yield strength of the aluminum profile is greatly improved. When the heat sink substrate 2 continues to move away from the extruder 1, the position of the second limiting roller 46 is first adjusted by the third electric telescopic rod 19. Then, the second motor 33 is started to drive the second limiting rollers 46 on both sides of the first mounting housing 21 to rotate simultaneously towards the heat sink substrate 2. The heat sink substrate 2 is first positioned laterally in the center. During this stage, the second limiting roller 46 limits the heat sink substrate 2 to positioning without applying clamping pressure. As the radiator substrate 2 continues to move, the T-shaped silicone plate 44 will engage with the heat dissipation teeth of the radiator substrate 2. Once the T-shaped silicone plate 44 is fully engaged, the fifth electric telescopic rod 25 drives the silicone plate 26 to press against the upper surface of the radiator substrate 2. At the same time, the second limiting roller 46 continues to rotate, thereby clamping the two sides of the radiator substrate 2. The internal grooves of the radiator substrate 2 are supported by the T-shaped silicone plate 44, forming a combined limiting with the external upper and lateral clamping, ensuring no vertical or horizontal movement during transport, greatly improving the stability of transport. Moreover, the height of the T-shaped silicone plate 44 is consistent with the heat dissipation teeth, thus forming an elastic support inside the grooves, evenly distributing the clamping pressure from above and both sides, and preventing deformation, indentation, or twisting of the heat dissipation teeth caused by compression. The outside of the T-shaped silicone plate 44 is wrapped with a flame-retardant absorbent cloth 24, which can absorb residual water in the heat dissipation grooves, increase frictional resistance to prevent slippage, and also act as a buffer to prevent scratches caused by rubbing against the grooves during engagement.

[0034] This device is adaptable to heat sink substrates 2 of different specifications and heat dissipation slots of different widths. By replacing the corresponding T-shaped silicone plate 44 and adjusting the installation position of the T-shaped silicone plate 44 inside the second mounting housing 23, precise engagement with the heat dissipation slots can be achieved. The T-shaped silicone plate 44 is fixedly connected to the second mounting block 30, and a magnetic block 31 is fixedly installed on the second mounting block 30. The pressing rod 28 limits the second mounting block 30 through the spring telescopic rod 29, and the first electromagnet 27 uses electromagnetic attraction to the magnetic block 31 to complete the fixation of the T-shaped silicone plate 44. When it is necessary to replace the T-shaped silicone plate 44, first disconnect the first electromagnet 27 to release the magnetic constraint, and then forcefully pull out all the original T-shaped silicone plates 44. Then, insert multiple T-shaped silicone plates 44 that match the width of the tooth grooves of the new heat sink substrate 2 into the second mounting housing 23. At this time, the second mounting block 30 of the replaced T-shaped silicone plate 44 will be limited and clamped by the extrusion rod 28, but the second mounting block 30 can still slide along the extrusion rod 28 inside the second mounting housing 23. At this time, the operator can fine-tune the position of the replaced T-shaped silicone plate 44 according to the position of the tooth grooves of the new heat sink substrate 2. After the position is calibrated, the first electromagnet 27 is activated to fix the replaced T-shaped silicone plate 44, completing the switching of the T-shaped silicone plate 44. This device adopts a dual fixing method of pre-limiting with the extrusion rod 28 and locking with the first electromagnet 27. Unlocking and locking can be completed by simply turning the first electromagnet 27 on and off. The newly installed T-shaped silicone plate 44 can slide freely and finely adjust its position to accurately align with the tooth grooves. After calibration, it can be locked by powering on, which greatly shortens the production line downtime. The spring telescopic rod 29 and the compression rod 28 can also prevent the T-shaped silicone plate 44 from falling off during replacement and adjustment. Electromagnetic adsorption ensures that the T-shaped silicone plate 44 does not shift or deviate during clamping, guaranteeing stable and reliable toothed support. In addition, when a single T-shaped silicone plate 44 is damaged, it can be removed and replaced individually without the need for overall disassembly, reducing downtime losses.

[0035] Subsequently, the second lead screw 13 drives the first sliding block 18 to move, thereby uniformly pulling the heat sink base plate 2. The moving heat sink base plate 2 will pass through the first fan 6 and the second fan 7 in sequence. The first fan 6 blows out low-pressure, room-temperature dry air to gently blow away the floating water on the surface of the heat sink base plate 2. It does not aim to dry it instantly, but only blows away large areas of flowing water, allowing the temperature of the heat sink base plate 2 to drop slowly and gradually, avoiding sudden cooling shock. After the temperature of the heat sink base plate 2 has dropped evenly, the second fan 7 blows out high-pressure cold air to deeply cool and dry the heat sink base plate 2.

[0036] While the second fan 7 is deeply cooling and drying the radiator substrate 2, the magnetic rod 35 is connected to the second electromagnet 34 via electromagnetic attraction. The operator can adjust the position of the magnetic rod 35 on the second electromagnet 34 according to the position of the T-shaped silicone plate 44 inside the second mounting housing 23. When the T-shaped silicone plate 44 moves above the first mounting plate 16, the end of the radiator substrate 2 is located on the second mounting plate 41. The first electric telescopic rod 10 is activated to move the L-shaped mounting plate 37 downward until it stops moving when it touches the radiator substrate 2. At the same time, the second electric telescopic rod 11 is activated to move the second electromagnet 34 downward, thereby causing the magnetic rod 35 to insert into the silicone mounting block 32. Subsequently, the sixth electric telescopic rod 40 is activated to move the first mounting plate 16 and the second mounting plate 41 upward. At this time, the first protrusion 39 on the first mounting plate 16 will be inserted into the first mounting housing 21, and the second protrusion 42 on the second mounting plate 41 will abut against the end of the radiator substrate 2. Subsequently, the sixth electric telescopic rod 40 continues to extend, causing the radiator base plate 2 to move upward to a certain height. Then, the sixth electric telescopic rod 40 connected to the second mounting plate 41 stops extending, while the sixth electric telescopic rod 40 connected to the first mounting plate 16 continues to extend. At the same time, the first motor 20 drives the first mounting housing 21 to rotate, thereby driving the radiator base plate 2 to rotate. Since the first mounting plate 16 and the second mounting plate 41 are both rotatably connected to the sixth electric telescopic rod 40 through the U-shaped mounting block 43, and the first electric telescopic rod 10 is rotatably connected to the mounting bracket 8, and the second electric telescopic rod 11 is rotatably connected to the second sliding block 36, during the rotation of the radiator base plate 2, the first mounting plate 16 and the second protrusion 42 can always support the bottom of the radiator base plate 2, and the magnetic rod 35 and the L-shaped mounting plate 37 also always limit the upper part of the radiator base plate 2. During the tilting process of the radiator base plate 2, water accumulated inside the grooves of the radiator base plate 2 will flow out from the end of the radiator base plate 2 under the action of gravity. It will then flow through the ramp on the L-shaped mounting block 38 into the conveying base 3. The conveying base 3 has an inclined guide channel inside, and the water flowing into the conveying base 3 will flow along the guide channel and finally be discharged from the outlet 12. This device utilizes the principle of gravity guidance to prevent water hidden deep inside the radiator grooves from accumulating and stagnating. It allows water to flow quickly from the end along the groove structure, effectively solving the problem that air blowing can only remove surface water from the radiator base plate 2 and cannot penetrate to clean deep water inside the grooves. Furthermore, this device can collect and direct the water flow, ultimately discharging it in an orderly manner through the outlet 12, preventing water from dripping indiscriminately and causing water accumulation and dirt buildup on the equipment platform.

[0037] After the water flows out from inside the radiator base plate 2, the first lead screw 9 is activated to move the second sliding block 36, which in turn moves the magnetic rod 35. At this time, the magnetic rod 35, which has been inserted into the silicone mounting block 32, will move the silicone mounting block 32. During the movement of the silicone mounting block 32, the sponge block 45, which was originally inserted into the T-shaped silicone plate 44, will be pulled out from the T-shaped silicone plate 44. As the silicone mounting block 32 continues to move, the sponge block 45 will slide along the inside of the heat dissipation groove, directly adhering to the inner wall of the groove, corner gaps and other blind spots, and absorbing the trace water stains remaining in the groove in all directions. This effectively avoids quality defects such as surface oxidation and spot corrosion caused by long-term residual moisture in the aluminum profile, and greatly improves the corrosion resistance and service life of the radiator base plate 2.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
