Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing, specifically a radiator fin flanging device. Background Technology

[0002] Heat sink fins are sheet-like structures mounted on the heat sink body. They are usually made of metals with good thermal conductivity, such as aluminum and copper. By increasing the heat dissipation surface area, they accelerate airflow or liquid convection and improve heat exchange efficiency.

[0003] When processing radiator fins, aluminum, copper, or copper-aluminum composite materials are first selected and made into foil, strip, or plate. The metal material is then formed into the basic shape of the fins through stamping, rolling, extrusion, and other methods. After that, the edges of the fins are bent to enhance the strength of the fins, improve heat dissipation performance, or meet specific installation requirements.

[0004] Thinner heat sink fins are easier to dissipate heat, but if they are too thin, they will affect the strength of the fins. Therefore, people usually fold the fins to strengthen them. During the folding process, the heat sink fins may shift or tilt, which may lead to uneven pressure and breakage. Therefore, a heat sink fin folding device is proposed to address the above problems.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5As shown in the figure, a radiator fin flanging device according to an embodiment of the present invention includes a base 1; a placement platform 11 is fixedly connected to the surface of the base 1; a plurality of electric push rods 12 are fixedly connected to the inner side wall of the placement platform 11; the electric push rods 12 are correspondingly arranged; a clamping plate 13 is fixedly connected to the output end of a group of electric push rods 12; a cylinder 14 is fixedly connected to one side of the placement platform 11; a U-shaped frame 15 is fixedly connected to the surface of the base 1; the U-shaped frame 15 is fixedly connected to one side of the placement platform 11; and a rotatable connection is made to the middle of the U-shaped frame 15. A first clamping roller 16; a second clamping roller 17 is slidably connected to the middle of the U-shaped frame 15; the second clamping roller 17 is positioned above the first clamping roller 16; a set of hydraulic cylinders 18 is fixedly connected to the top of the U-shaped frame 15; a buffer device 19 is installed at the output end of the hydraulic cylinders 18; a pressure plate 110 is installed at the bottom of the buffer device 19; during operation, the heat dissipation fins are placed on the surface of the placement table 11, and the cylinder 14 is controlled to extend and retract its output end to push the heat dissipation fins to the required processing position, and then the middle of the placement table 11 is controlled... The electric actuator 12 extends and retracts, causing a set of clamping plates 13 to clamp both sides of the heat dissipation fins. Then, the second clamping roller 17 is controlled to slide in the middle of the U-shaped frame 15, causing the second clamping roller 17 and the first clamping roller 16 to clamp one end of the heat dissipation fins. Next, a set of hydraulic cylinders 18 extends and retracts, causing the pressure plate 110 to press downwards against the end of the heat dissipation fins, bending the end along the surface of the first clamping roller 16. After a period of pause, the hydraulic cylinders 18 are again extended and retracted to lift the pressure plate 110, completing the flanging of the heat dissipation fins. This is then achieved by the cylinder 14... When the fins reach the designated processing position, the flanging positions are aligned. The cooperation between the electric push rod 12, clamping plate 13, first clamping roller 16 and second clamping roller 17 fixes the two sides and ends of the heat dissipation fins to form a three-dimensional fixation, so that the flanging force is evenly transmitted to the entire fin. A set of clamping plates 13 clamps the two sides of the heat dissipation fins to reduce the lateral displacement of the heat dissipation fins, which would cause the flanging angle to be skewed. The first clamping roller 16 and the second clamping roller 17 reduce the vertical floating of the heat dissipation fins and reduce the inconsistent flanging height caused by the fins lifting up during flanging.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the top of the U-shaped frame 15 has multiple air outlets 2; a distributor 21 is fixedly connected to the top of the U-shaped frame 15; the air outlets 2 are connected to the distributor 21; the distributor 21 is connected to an air pipe 22; an air pump is installed at the end of the air pipe 22; during operation, the air pump is turned on so that the gas enters the distributor 21 through the air pipe 22 and is then dispersed into multiple streams and blown out from the multiple air outlets 2. By blowing the gas out from the multiple air outlets 2, the gas can cover the flanged area of ​​the fins, blowing away the burrs, debris, etc. generated during flanged operation, reducing their accumulation on the surface of the pressure plate 110 or the fin surface, thus preventing scratches on the fin surface.

[0028] like Figures 4 to 5As shown, a heating wire 3 is installed in the middle of the first clamping roller 16; a heating wire 3 is installed in the middle of the second clamping roller 17. During operation, the switch of the heating wire 3 is turned on, so that the heat emitted by the heating wire 3 is transferred to the contact surface of the heat dissipation fins through the first clamping roller 16 and the second clamping roller 17 for heating. By installing the heating wire 3 inside the first clamping roller 16 and the second clamping roller 17, the heat dissipation fins can be heated, increasing their ductility, so that they can undergo better plastic deformation during the flanging process, reducing the generation of wrinkles and twists, and reducing the risk of breakage.

[0029] like Figures 4 to 5 As shown, the buffer device 19 includes a spring telescopic rod 4; the spring telescopic rod 4 is fixedly connected to the output end of the hydraulic cylinder 18; the output end of the spring telescopic rod 4 is fixedly connected to the pressure plate 110; the spring telescopic rod 4 is arranged between the hydraulic cylinder 18 and the pressure plate 110; during operation, when the output end of a set of hydraulic cylinders 18 extends and retracts to make the pressure plate 110 contact the surface of the heat dissipation fins, the spring telescopic rod 4 extends and retracts to reduce part of the pressure of the hydraulic cylinder 18. By setting the spring telescopic rod 4, after the pressure plate 110 contacts the fins, the spring telescopic rod 4 will be compressed, thereby reducing the instantaneous pressure transmitted to the fins, making the pressure more uniform and slow to be applied, reducing the deformation and cracking of the fins due to excessive force, and also reducing the wear of the pressure plate 110, increasing the integrity and quality of the fins.

[0030] like Figures 4 to 5 As shown, a silicone pad 5 is fixed to the surface of the buffer device 19; the silicone pad 5 is disposed on the side that contacts the heat dissipation fins; during operation, the silicone pad 5 is placed between the heat dissipation fins and the pressure plate 110, and adapts to the shape and surface characteristics of the heat dissipation fins. The silicone pad 5 can fill the micro gap between the pressure plate 110 and the fins. At the moment of contact between the pressure plate 110 and the heat dissipation fins, the silicone pad 5 absorbs the impact force through its own deformation, reducing the damage such as indentations, cracks or tears on the fin surface caused by the pressure plate 110.

[0031] like Figures 1 to 2 As shown, multiple rollers 6 are rotatably connected to the surface of the placement platform 11; the rollers 6 are arranged between a set of clamping plates 13; during operation, when the output end of the cylinder 14 extends and retracts to adjust the position of the heat dissipation fins, the contact surface between the rollers 6 and the heat dissipation fins generates friction, causing the rollers 6 to rotate, making it easier for the output end of the cylinder 14 to adjust the position of the heat dissipation fins. By setting multiple rollers 6, the friction between the output end of the cylinder 14 and the surface of the placement platform 11 when pushing the heat dissipation fins to move can be reduced, allowing the cylinder 14 to adjust the position of the heat dissipation fins more quickly and improving the flanging efficiency. The rollers 6 can reduce the direct contact between the placement platform 11 and the heat dissipation fins, maintain the integrity of the heat dissipation fins, and increase the service life of the placement platform 11.

[0032] like Figures 1 to 3As shown, a collection baffle 7 is fixedly attached to the surface of the base 1; multiple air intakes 71 are provided on one side of the collection baffle 7; a collection channel 72 is connected to one side of the collection baffle 7; the air intakes 71 and the collection channel 72 are connected; an air intake device is installed at the end of the collection channel 72; during operation, the collection baffle 7 prevents the debris generated during the processing of the pressure plate 110 from being blown away by the gas blown out of the air outlet 2, causing the debris to accumulate in the middle of the collection baffle 7. Then, the air intake device is turned on, and the debris on the surface of the base 1 enters the collection channel 72 through the air intakes 71 and is then sucked out. By sucking out the debris generated during the processing of the pressure plate 110, the debris on the surface of the base 1 can be reduced from being blown away by the gas blown out of the air outlet 2 and adsorbed on the pressure plate 110, which would scratch the surface of the heat dissipation fins. In conjunction with the air outlet 2, the airflow can be accelerated, so that the heat dissipation fins can be cooled and shaped after the edge is turned over, reducing the rebound of the edge.

[0033] like Figures 1 to 3 As shown, a set of sliding grooves 8 are provided on the inner side wall of the placement platform 11; the set of sliding grooves 8 are arranged correspondingly; a slider 81 is slidably connected in the middle of the sliding groove 8; a connecting plate 82 is fixed between the set of sliders 81; a brush 83 is fixedly connected to the bottom of the connecting plate 82; the brush 83 is in contact with the base 1; during operation, the set of sliders 81 slides in the middle of the set of sliding grooves 8, so that the connecting plate 82, along with the brush 83, pushes the debris on the surface of the base 1 to the side close to the collection baffle 7. By sliding the sliders 81 in the middle of the set of sliding grooves 8, the accumulation of debris under the placement platform 11 can be reduced, the cleaning dead corner of the air intake 71 can be reduced, and the centralized collection can directly transport the debris to the recycling device for subsequent unified processing or recycling.

[0034] Working principle: By placing the heat dissipation fins on the surface of the placement table 11, the output end of the cylinder 14 is extended and retracted to push the heat dissipation fins to the required processing position. Then, the electric push rod 12 in the middle of the placement table 11 is extended and retracted, so that a set of clamping plates 13 clamps both sides of the heat dissipation fins. Subsequently, the second clamping roller 17 is controlled to slide in the middle of the U-shaped frame 15, so that the second clamping roller 17 and the first clamping roller 16 clamp one end of the heat dissipation fins. Then, a set of hydraulic cylinders 18 is extended and retracted, so that the pressure plate 110 presses down on the end of the heat dissipation fins, so that the end bends along the surface of the first clamping roller 16. After a period of time, the hydraulic cylinder 18 is extended and retracted again to lift the pressure plate 110, completing the flanging of the heat dissipation fins. The air pump is turned on, so that the air enters the distributor 21 through the air pipe 22 and is then dispersed into multiple streams and blown out from multiple air outlets 2. The heating wire 3 is turned on, so that the heat emitted by the heating wire 3 is transferred to the contact surface of the heat dissipation fins through the first clamping roller 16 and the second clamping roller 17. Heating is performed on the upper part. When the output end of a set of hydraulic cylinders 18 extends and retracts to make the pressure plate 110 contact the surface of the heat dissipation fins, the spring extension rod 4 extends and retracts to reduce part of the pressure of the hydraulic cylinder 18. The silicone pad 5 is placed between the heat dissipation fins and the pressure plate 110 and adapts to the shape and surface characteristics of the heat dissipation fins. When the output end of the cylinder 14 extends and retracts to adjust the position of the heat dissipation fins, the contact surface between the roller 6 and the heat dissipation fins generates friction, which drives the roller 6 to rotate, making it easier for the output end of the cylinder 14 to adjust the position of the heat dissipation fins. The collecting baffle 7 prevents the debris generated during the processing of the pressure plate 110 from being blown away by the gas blown out of the air outlet 2, so that the debris gathers in the middle of the collecting baffle 7. Then the suction device is turned on, and the debris on the surface of the base 1 enters the collecting channel 72 through the suction port 71 and is sucked out. A set of sliders 81 slides in the middle of a set of sliding grooves 8, so that the connecting plate 82 with the brush 83 pushes the debris on the surface of the base 1 to the side close to the collecting baffle 7.
