Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a continuous polishing device and method for the surface of die-cast radiator fins. Background Technology

[0002] As an indispensable heat transfer device in mechanical and electronic equipment, the heat dissipation efficiency of a radiator directly affects the stability and lifespan of the entire machine. Among the many radiator forming processes, die casting has become the mainstream technology for radiator production because it can form fins into thin, dense, irregular, and other complex structures, effectively increasing the heat exchange area and adapting to fan airflow requirements. Moreover, the process is relatively simple. However, during the die casting process, the molten aluminum liquid rapidly fills and solidifies in the mold cavity, making it difficult to avoid the formation of defects such as flow lines and oxide slag on the fin surface. These surface impurities will significantly increase thermal resistance and weaken the overall heat dissipation performance. Therefore, after die casting, the outer surface of the fins needs to be polished to remove the above defects, improve surface quality, and thus ensure its heat dissipation effect.

[0003] Patent document CN118386087B discloses a polishing device for surface treatment of die-cast radiator fins. This solution uses a lifting and transfer assembly in conjunction with the lifting action of a support plate to transfer the radiator within the same device during loading, polishing, and unloading, without interference between the stages. During operation, the rotating polishing assembly polishes the fins from both sides, and the feed rate is controlled by an electrically controlled telescopic cylinder. The jet polishing assembly uses jetted fluid abrasive particles to perform secondary polishing on the inner surface of the fin gaps. The combination of polishing and jet polishing compensates for the shortcomings of a single processing method. However, this device still has limitations in application: First, it adopts a serial operation mode of "single workpiece lifting and transfer," where the next workpiece can only enter after all the processes of the previous workpiece are completed and pushed out, resulting in a break in the process cycle and making it unsuitable for continuous production line requirements. Second, although the jet assembly can act inside the gaps, the jet angle is relatively fixed, and the penetration and scouring ability of the abrasive flow into the deep narrow gaps is limited, making it difficult to guarantee the polishing effect for deep dead corners.

[0004] Based on this, we now provide equipment and methods for continuous polishing of the surface of die-cast radiator fins, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

This allows processes such as feeding, double-sided grinding and polishing, end face grinding and polishing, chemical polishing and drying to be carried out simultaneously and in parallel, greatly shortening the single-piece processing cycle and enabling continuous polishing of heat sink fins.

[0016] 2. This invention introduces a chemical polishing process that integrates heating and ultrasonic vibration. It utilizes a mixture of phosphoric acid, sulfuric acid, and nitric acid, combined with constant temperature heating, to effectively activate the reaction. Then, with the help of the "cavitation effect" generated by ultrasound, strong micro-jets and shock waves are generated inside the narrow gaps, forcibly squeezing the chemical solution into every tiny gap and blasting off the attached substances. This composite treatment method can deeply remove stubborn oxide scale and residual abrasive particles, ensuring that the quality of the entire fin surface is uniform.

[0017] 3. This invention, by setting an adjustable grinding column mechanism and a dual-sided switching mechanism, enables the grinding fixture to flexibly adapt to different fin arrangement spacings and dual-sided surfaces, avoiding local over-cutting or under-polishing caused by a single grinding posture. At the same time, it adopts a multi-level progressive processing chain that combines grinding and deep chemical polishing, from macroscopic shape trimming to microscopic surface oxide layer removal, gradually eliminating various surface defects, effectively reducing surface thermal resistance, and significantly improving the appearance quality, surface precision and overall heat dissipation efficiency of the final product.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0033] In one embodiment, such as Figures 1-13As shown, the continuous polishing equipment for the surface of die-cast radiator fins includes a processing box 11. Conveyor belts 12 are symmetrically arranged inside the processing box 11. A plurality of supporting components 19 are arrayed between two of the conveyor belts 12. These supporting components 19 are used for continuous polishing and conveying of the radiator body 78. Inside the processing box 11, along the conveying direction of the conveyor belts 12, a first polishing component 20, a second polishing component 21, and a third polishing component are sequentially arranged. The first polishing component 20 is used to polish both sides of the upper fins of the radiator body 78. The second polishing component 21 is used to polish the upper end of the fins. The third polishing component is used to chemically impregnate and polish the fins on the radiator body 78. Each supporting component 19 includes a supporting seat 27, which is fixedly connected to the conveyor belt 12 via a connecting seat. A guide seat 32 is provided above the support seat 27. A movable seat 31 is slidably provided on the upper end of the guide seat 32. A clamping seat 28 is installed on the upper end of the movable seat 31. A push rod 34 is fixedly provided on the bottom end of the guide seat 32. A switching mechanism is provided on the guide seat 32 to facilitate double-sided polishing of the radiator body 78. The first polishing component 20 includes a transmission component 47. Several mounting seats 46 are arrayed on the bottom end of the transmission component 47. A grinding column 45 is installed at the end of the mounting seat 46. The input end of the transmission component 47 is fixedly connected to the output end of the second motor 48. An adjustment mechanism for adjusting the polishing spacing of the grinding column 45 is provided inside the processing box 11. The switching mechanism facilitates the grinding column 45 to polish both sides of the fins. The adjustment mechanism facilitates the polishing of fins with different arrangement spacings. Chains are fitted on both sides of the conveyor belt 12, and four sprockets 13 are fitted on the inner side of each chain. Four support rollers are fitted on the inner side of the conveyor belt 12. The support rollers and the sprockets 13 on both sides of the support rollers are all mounted on the same first mounting shaft. The coaxial first mounting shaft is mounted on the same first fixed frame 14, which is fixedly located inside the processing box 11. A driven gear ring 15 is provided in the middle of one of the support rollers on the inner side of the conveyor belt 12. Each driven gear ring 15 is meshed with a driving gear 16. Two driving gears 16 are fixedly mounted on a second mounting shaft, which is mounted on the first fixed frame 14. The end of the first mounting shaft corresponding to one driven gear ring 15 is fixedly connected to the output end of a reducer. The input end of the reducer is fixedly connected to the output end of a first motor 17. The first motor 17 is electrically connected to a control component 18. The reducer, the first motor 17, and the control component 18 are all mounted on one side of the processing box 11. The processing box 11 is provided with a feeding port near the end of the first motor 17. The bottom of the bearing seat 27 is symmetrically provided with support rods corresponding to the conveyor belt 12. When continuous processing of the radiator body 78 is required, the first motor 17 is started by the control component 18. The output end of the first motor 17 drives a first mounting shaft to rotate through a reducer. The first mounting shaft drives the corresponding driven gear ring 15, support roller and sprocket 13 to rotate. At the same time, the driven gear ring 15 meshes with the drive gear 16 to drive the second mounting shaft to rotate. The second mounting shaft drives the coaxially set first mounting shaft to rotate through another set of driven gear ring 15 and drive gear 16, so that the two conveyor belts 12 rotate synchronously. The conveyor belts 12 drive several bearing components 19 to move in a cycle. According to the processing needs, the output end of the first motor 17 drives the conveyor belt 12 to rotate intermittently. When a bearing component 19 moves to the feeding port and stops, the radiator body 78 to be polished can be installed on the upper end of the clamping seat 28.

[0034] The clamping seat 28 is symmetrically provided with first limiting frames at its upper end. A second limiting frame is provided between one end of the two first limiting frames. Both the first and second limiting frames have L-shaped cross-sections. A limiting frame 29 is provided between the other ends of the two first limiting frames. The limiting frame 29 is slidably disposed in the mounting groove inside the clamping seat 28. A first return spring 30 is symmetrically provided between the bottom end of the limiting frame 29 and the bottom end of the mounting groove. A handle is fixedly provided on one side of the limiting frame 29. The clamping seat 28 is symmetrically provided with sliding blocks at its bottom end. A first guide slide rod is slidably disposed in the sliding hole in the middle of each sliding block. A sliding plate is fixedly provided at the bottom end of the clamping seat 28. A second guide slide rod is slidably disposed in the sliding hole in the middle of the sliding plate. Both the first and second guide slide rods are fixedly disposed inside the guide seat 32. A second return spring 33 is fixedly disposed between one side of the sliding plate and one end inside the guide seat 32. The processing box 11 is aligned with the area below the transmission component 47. The device is equipped with a second electric cylinder 54. The telescopic end of the second electric cylinder 54 is at the same height as the upper clamping seat 28 of the conveyor belt 12. In use, when the conveyor belt 12 drives the radiator body 78 to move below the transmission component 47 and stops via the bearing seat 27, the end of the grinding column 45 descends to the upper end of the radiator body 78, so that multiple grinding columns 45 are respectively located on one side of the corresponding fin. Then, the control component 18 controls the second electric cylinder 54 to start. After the end of the second electric cylinder 54 is in close contact with the end of the clamping seat 28, the telescopic end of the second electric cylinder 54 pushes the clamping seat 28 to move along the length direction of the guide seat 32, so that the clamping seat 28 drives the radiator body 78 to move. When the radiator body 78 passes the end of the grinding column 45, the grinding column 45 can grind and polish one side of the fin. After the clamping seat 28 moves to the other end of the guide seat 32, the telescopic end of the second electric cylinder 54 retracts, so that the grinding column 45 performs secondary grinding and polishing on one side of the fin.

[0035] The switching mechanism includes a cam lift divider 55, which is located below the first polishing component 20 and fixedly installed inside the processing box 11. The working end of the cam lift divider 55 is located below the push rod 34. Each end of the push rod 34 is fixedly provided with a docking seat 38. The working end of the cam lift divider 55 is fixedly provided with a first mating joint. Each push rod 34 is slidably provided with a limiting tube 35, which is fixedly installed within the inner ring of a bearing 36. The bearing 36 is installed inside a fixed box, which is fixedly installed on a bearing... At the upper end of the seat 27, a third return spring 37 is provided between the bottom end of the limiting tube 35 and the upper end of the docking seat 38. A first limiting ring 39 is fixedly provided at the bottom end of the guide seat 32. A second limiting ring 40 is provided below the first limiting ring 39. The second limiting ring 40 is fixedly provided at the upper end of the bearing seat 27 and is coaxially arranged with the bearing 36. A first support seat 41 is symmetrically provided at the bottom end of the guide seat 32. A second support seat 43 is provided at the upper end of the bearing seat 27 at a position corresponding to the first support seat 41. A first magnet 42 is installed at the bottom end of each first support seat 41. The second support base 43 is equipped with a second magnet 44 at its upper end. During use, after the grinding column 45 completes the single-sided secondary polishing of the fins, the control component 18 controls the cam lifting divider 55 to start. The working end of the cam lifting divider 55 first extends, allowing the first connector of the working end of the cam lifting divider 55 to insert into the bottom end of the docking seat 38. Then, the working end of the cam lifting divider 55 pushes the guide seat 32 upwards via the push rod 34, causing the first limiting ring 39 to separate from the second limiting ring 40. Subsequently, the working end of the cam lifting divider 55 drives the guide seat 32 to rotate 180 degrees. After the switching is complete, the first… The connector separates from the mating seat 38. Under the action of the third return spring 37, the guide seat 32 is reset. The first magnet 42 and the second magnet 44 attract each other, thereby helping to fix the guide seat 32. At the same time, the first limit ring 39 and the second limit ring 40 cooperate to prevent the guide seat 32 from deflecting. Then, the control component 18 starts another second electric cylinder 54, so that the extension end of the second electric cylinder 54 pushes the clamping seat 28 to slide again, thereby performing secondary grinding and polishing on the other side of the fin. Then, the cam lifting divider 55 is started again, thereby resetting the position of the clamping seat 28.

[0036] The adjusting mechanism includes a first mounting box 49, and the transmission component 47 is installed inside the first mounting box 49. A third mounting shaft is fixedly mounted on the upper end of the first mounting box 49, and a worm gear 50 is fixedly mounted on the third mounting shaft. A worm 51 is meshed on the worm gear 50. The worm 51 is rotatably mounted inside a connecting box, and one end of the worm 51 is fixedly connected to the output end of a third motor 52. The third motor 52 is fixedly mounted on one side of the connecting box, and the connecting box is fixedly mounted on the telescopic end of a first electric cylinder 53. The first electric cylinder 53 is fixedly mounted inside the upper end of the processing box 11. During use, it is necessary to adjust different arrangements... When the fins are being polished, the third motor 52 is started by the control component 18. The output of the third motor 52 drives the worm 51 to rotate. The worm 51 meshes with the worm wheel 50 to drive the third mounting shaft to rotate. The third mounting shaft drives the transmission component 47 to rotate through the first mounting box 49, thereby adjusting the horizontal working angle of the transmission component 47. Since the fins are arranged vertically, the transmission component 47 is set at an angle relative to the fins, thereby adjusting the working angle of the polishing column 45. At the same time, the transmission component 47 has a transmission structure inside, so that the second motor 48 can drive several mounting seats 46 to rotate synchronously.

[0037] The second polishing component 21 includes a polishing belt 56, with transmission rollers at both ends. The transmission rollers are rotatably mounted inside the second mounting box. One end of the transmission roller is fixedly connected to the output end of the fourth motor 57. The fourth motor 57 is fixedly mounted on one side of the second mounting box. The second mounting box is fixedly mounted on the telescopic end of the third electric cylinder 58. The third electric cylinder 58 is fixedly mounted inside the upper part of the processing box 11. The upper part of the second mounting box is fixedly connected to the telescopic ends of two telescopic rods 59. The telescopic rods 59 are fixedly mounted inside the upper part of the processing box 11. In use, after the polishing column 45 polishes the fins, the conveyor belt 12 moves the radiator body 78 to below the polishing belt 56. Then, the telescopic end of the third electric cylinder 58 drives the polishing belt 56 to descend, so that the bottom end of the polishing belt 56 is in close contact with the upper end of the fins. The fourth motor 57 is started, and the output end of the fourth motor 57 drives the transmission rollers to rotate, thereby driving the polishing belt 56 to rotate, thus polishing the upper end of the fins.

[0038] A baffle 60 is provided inside the processing box 11 and below the first polishing component 20 and the second polishing component 21. The baffle 60 is inclined. A first waste residue box 61 is provided inside the processing box 11 and at the end of the baffle 60. A second waste residue box 62 is provided at the bottom of the processing box 11 and below the end of the conveyor belt 12. Both sides of the guide seat 32 are provided with slag discharge ports. In use, when the fins are polished, the generated debris falls onto the upper end of the baffle 60. Since the baffle 60 is inclined, the first waste residue box 61 can collect the debris. Subsequently, when the support seat 27 moves to the end of the conveyor belt 12, the support seat 27 is set at 90 degrees, so that the debris inside the guide seat 32 is discharged through the slag discharge port, and the second waste residue box 62 can collect the debris.

[0039] The third polishing component includes a first cleaning tank 22, a chemical polishing tank 23, a collection tank 24, a second cleaning tank 25, and a drying tank 26. These components are arranged sequentially along the rotation direction of the conveyor belt 12.

During use, when the radiator body 78 passes sequentially through the first cleaning box 22, chemical polishing box 23, collection box 24, second cleaning box 25, and drying box 26, the corresponding extension end of the fourth electric cylinder 75 drives the second connector 73 to move, causing the second connector 73 to insert into the end of the push rod 34, positioning the radiator body 78 on one side of the first rinsing seat 63. Subsequently, the output end of the fifth electric motor 74 can drive the radiator body 78 to rotate, causing the first rinsing seat 63 to rotate relative to the radiator body. The radiator body 78 undergoes multi-angle cleaning, followed by repeated operation, immersing it in a mixture of phosphoric acid, sulfuric acid, and nitric acid inside the chemical polishing tank 23. The heater 66 heats the chemical mixture, while the immersion ultrasonic vibrating box 65 utilizes the ultrasonic cavitation effect to generate micro-jets and shock waves within the fin gaps, forcibly squeezing the chemical agents into every tiny crevice and blasting off attached bubbles and reaction residues. This significantly improves the treatment effect on stubborn impurities and micropores, ensuring a high degree of consistency in surface quality. After the radiator body 78 moves above the collection box 24, excess chemical agents can be discharged into the collection box 24. After the radiator body 78 moves into the second cleaning tank 25, the second rinsing seat 69 can rinse the radiator body 78.The chemicals on the radiator body 78 are then rinsed off. Afterward, the radiator body 78 is moved into the drying chamber 26, where hot air is expelled from the drying base 70, and the radiator body 78 rotates, thus accelerating the drying process. Example 2

[0040] The difference from Embodiment 1 is that: the bearing seat 27 is symmetrically provided with fixed columns at both ends, and the fixed columns are rotatably provided with support rollers 76. The processing box 11 is provided with support rails 77 that cooperate with the support rollers 76 at the upper and lower ends of the conveyor belt 12. In use, the support rollers 76 cooperate with the support rails 77 to support the bearing seat 27, thereby preventing the conveyor belt 12 from undergoing large deformation.

[0041] The above embodiments disclose a continuous polishing equipment for the surface of die-cast radiator fins. When continuous processing of the radiator body 78 is required, the control component 18 controls the start of the first motor 17. The output end of the first motor 17 drives a first mounting shaft to rotate through a reducer. The first mounting shaft drives the corresponding driven gear ring 15, support roller and sprocket 13 to rotate. At the same time, the driven gear ring 15 meshes with the drive gear 16 to drive the second mounting shaft to rotate. The second mounting shaft drives the coaxially arranged first mounting shaft to rotate through another set of driven gear rings 15 and drive gear 16, so that the two conveyor belts 12 rotate synchronously. The conveyor belts 12 drive several bearing components 19 to move in a cycle. According to the processing needs, the output end of the first motor 17 drives the conveyor belt 12 to rotate intermittently. When a bearing component 19 moves to the loading port and stops, the radiator body 78 to be polished can be installed on the upper end of the clamping seat 28. The radiator body 78 is placed between the first limit frame and the second limit frame. Finally, the radiator body 78 is fixed by the limit frame 29. When the conveyor belt 12 moves the radiator body 78 to below the transmission component 47 via the carrier seat 27 and stops, the end of the grinding column 45 descends to the upper end of the radiator body 78, so that multiple grinding columns 45 are respectively located on one side of the corresponding fins. Then, the control component 18 controls the second electric cylinder 54 to start. After the end of the second electric cylinder 54 is in close contact with the end of the clamping seat 28, the telescopic end of the second electric cylinder 54 pushes the clamping seat 28 to move along the length direction of the guide seat 32, so that the clamping seat 28 drives the radiator body 78 to move. When the radiator body 78 passes the end of the grinding column 45, the grinding column 45 can grind and polish one side of the fins. After the clamping seat 28 moves to the other end of the guide seat 32, the telescopic end of the second electric cylinder 54 retracts, so that the grinding column 45 performs secondary grinding and polishing on one side of the fins. Then, the control component 18 controls the cam lifting divider 55 to start. The working end of the cam lifting divider 55 first extends, so that the cam lifts... The first connector of the working end of the cam lift divider 55 is inserted into the bottom end of the docking seat 38. Then, the working end of the cam lift divider 55 pushes the guide seat 32 up through the push rod 34, causing the first limit ring 39 to separate from the second limit ring 40. Then, the working end of the cam lift divider 55 drives the guide seat 32 to rotate 180 degrees. After the switching is completed, the first connector separates from the docking seat 38. Under the action of the third return spring 37, the guide seat 32 is reset. The first magnet 42 and the second magnet 44 attract each other, thereby helping to fix the guide seat 32. At the same time, the first limit ring 39 and the second limit ring 40 cooperate to prevent the guide seat 32 from deflecting. Then, the control component 18 starts another second electric cylinder 54, causing the extension end of the second electric cylinder 54 to push the clamping seat 28 to slide again, thereby performing secondary grinding and polishing on the other side of the fin. Then, the cam lift divider 55 starts again, thereby resetting the position of the clamping seat 28. The conveyor belt 12 moves the radiator body 78 to below the polishing belt 56. Then, the extension end of the third electric cylinder 58 drives the polishing belt 56 to descend, so that the bottom end of the polishing belt 56 is in close contact with the upper end of the fins. The fourth motor 57 is started, and the output end of the fourth motor 57 drives the transmission roller to rotate, which in turn drives the polishing belt 56 to rotate, thereby polishing the upper end of the fins. During the polishing of the fins, the generated debris falls onto the upper end of the baffle 60. Since the baffle 60 is inclined, the first waste bin 61 can collect the debris. Then, when the support seat 27 moves to the end of the conveyor belt 12, the support seat 27 is set at 90 degrees, so that the debris inside the guide seat 32 is discharged through the slag discharge port, and the second waste bin 62 can collect the debris. Subsequently, the conveyor belt 12 moves the radiator body 78 below the conveyor belt 12. As the radiator body 78 passes sequentially through the first cleaning box 22, the chemical polishing box 23, the collection box 24, the second cleaning box 25, and the drying box 26, the corresponding fourth electric cylinder 75's telescopic end moves the second connector 73, causing the second connector 73 to insert into the end of the push rod 34, positioning the radiator body 78 on one side of the first flushing seat 63. Then, the output end of the fifth motor 74 can drive the radiator body 78 to rotate, causing the first flushing seat 63 to clean the radiator body 78 from multiple angles. This process is repeated, immersing the radiator body 78 in the mixture of phosphoric acid, sulfuric acid, and nitric acid inside the chemical polishing box 23. The heater 66 heats the mixed chemical solution, while the immersion ultrasonic transducer 65 utilizes the ultrasonic "cavitation effect" to generate micro-cavitation within the fin gaps. The jet and shockwave forcefully squeeze the chemical agent into every tiny crevice, blasting away attached bubbles and reaction residues, greatly improving the treatment effect on stubborn impurities and micropores, ensuring a high degree of consistency in surface quality. After the radiator body 78 moves above the collection box 24, excess chemical agent can be discharged into the collection box 24. After the radiator body 78 moves into the second cleaning box 25, the second rinsing seat 69 can rinse the radiator body 78, thereby rinsing off the chemical agent on the radiator body 78. Subsequently, after the radiator body 78 moves into the drying box 26, the drying seat 70 discharges hot air, and the radiator body 78 rotates, thereby accelerating the drying of the radiator body 78. When the radiator body 78 moves to the loading port, the operator removes the polished radiator body 78 and reloads it, thus completing the continuous polishing process.
