Description

Technical Field

[0001] This utility model relates to the field of aluminum plate punching technology, specifically to an aluminum plate punching device. Background Technology

[0002] The one-piece molded aluminum heat sink fins used in graphics card PCBs need to be punched by a punching machine so that heat dissipation components can be installed later. They are widely used in the heat dissipation modules of electronic devices such as graphics cards.

[0003] Existing aluminum plate punching devices suffer from the following technical defects: the aluminum heat sinks used in graphics card PCBs are typically thin, and aluminum itself has high ductility and low hardness. During high-pressure punching, the aluminum plate is prone to plastic deformation, causing the heat sink fins to become misaligned or twisted. This deformation disrupts the uniformity of the heat dissipation airflow, disturbs airflow organization, and reduces heat dissipation efficiency. When such heat dissipation modules are actually installed in graphics cards, their inadequate heat dissipation performance often affects the stable operation and overall performance of the graphics card. Utility Model Content

[0004] This utility model provides an aluminum plate punching device, which has the advantage of preventing the aluminum plate from deforming during punching. This solves the problem that in the prior art, aluminum plate heat sinks are mostly used for heat dissipation of graphics cards, etc. Because the aluminum fins of the heat sinks installed on the graphics card PCB are relatively thin and aluminum has high ductility and low hardness, the heat sink is easily deformed when high pressure punching is used. This causes the heat sink fins to bend and the heat dissipation channel to be uneven, resulting in poor working condition when installed on graphics cards and other equipment.

[0005] To prevent deformation of aluminum plates during punching, this utility model provides the following technical solution: an aluminum plate punching device, including a machine base and a punching device, wherein a punching component is installed on the top surface of the machine base, the punching component includes a first platform, the first platform is installed at one end of the top surface of the machine base, a first guide block is slidably connected to the top surface of the first platform, and a second guide block is fixedly connected to the top surface of the first guide block.

[0007] As a preferred technical solution of this utility model, a functional component is provided on one side of the drilling assembly.

[0016] 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 protection scope of the present utility model. Example 1

[0017] Please see Figures 1-2 This utility model discloses an aluminum plate punching device, a machine base 1, a punching assembly 2 mounted on the top surface of the machine base 1, a functional component 3 disposed on one side of the punching assembly 2, and an mounting assembly 4 disposed on the upper part of the functional component 3, wherein: The punching assembly 2 includes a punching device 24, which is slidably connected to the top surface of the machine base 1; The functional component 3 includes a mounting frame 30, the bottom of which is provided with an electric telescopic rod 31, and the top surface of the electric telescopic rod 31 is rotatably connected to a base plate 34 for driving the aluminum plate to rotate. The mounting assembly 4 includes an extension rod 40, on the bottom surface of which an mounting plate 41 is mounted. A slotted plate 44 is inserted into the bottom surface of the mounting plate 41, and an insertion block 45 for preventing deformation of the aluminum plate during punching is installed on the inner wall of the slotted plate 44.

[0018] It is important to note that the bottom surface of the insertion block 45 is designed to accommodate different spacing of the heat dissipation fins on the aluminum heat dissipation plate. Its material is either relatively hard and smooth, and lubricant or cooling oil residue may remain on its surface during the aluminum heat dissipation plate processing, making insertion and removal easy. The insertion block 45 is also designed to be detachable, facilitating the insertion of aluminum plates of different sizes and with varying fin spacing. The holes in the insertion block 45 are pre-drilled according to the openings in the aluminum heat dissipation plate to maintain the insertion position during punching.

[0019] Furthermore, the drilling assembly 2 also includes a first platform 20, which is mounted on one end of the top surface of the machine base 1. A first guide block 21 is slidably connected to the top surface of the first platform 20, and a second guide block 23 is fixedly connected to the top surface of the first guide block 21.

[0020] Furthermore, the top surface of the second guide block 23 is slidably connected to the second platform 22, the top surface of the second platform 22 is fixedly connected to the bottom surface of the drilling device 24, and the drilling end of the drilling device 24 corresponds to the mounting component 4 and the functional component 3.

[0021] It should be noted that a controller is installed on one side of the machine tool 1 and is electrically connected to the first guide block 21, the second guide block 23, the drilling device 24, the electric telescopic rod 31, and the servo motor 33 respectively, for controlling the operation of these spaces.

[0022] The controller automatically calculates the height of the electric telescopic rod 31, the movement trajectory of the first guide block 21 and the second guide block 23, and presets the rotation angle of the servo motor 33. Based on the input heat dissipation fin spacing parameters, it selects the corresponding bottom-designed insertion block 45 from the tool library. The insertion block 45 is inserted into the inner wall of the slot plate 44 and locked in place by the fixing block 42 and fixing bolt 43, ensuring the insertion block 45 is secure. The pre-drilled hole in the insertion block 45 is confirmed to be aligned with the target punching position on the aluminum plate. The aluminum plate with pre-processed heat dissipation fins is placed flat on the top surface of the base plate 34, allowing the heat dissipation fins to embed into the limiting groove 35 on the surface of the base plate 34. The aluminum plate is naturally fitted using the side wall of the limiting groove 35 or gravity, ensuring no horizontal displacement. The first guide block 21 and the second guide block 23 are fine-tuned to align the punch center with the first punching position on the aluminum plate. The punching equipment 24 is started to punch holes; the controller controls the electric telescopic rod 31 to rise, and the insertion block 45 is simultaneously embedded in the area around the hole. Its hard surface and the contact surface of the aluminum plate form a local rigid support to disperse the punching stress. Example 2

[0023] Based on the above embodiment 1, please refer to Figures 3-6The functional component 3 also includes a support plate 32. The electric telescopic rods 31 are arranged in a rectangular array at the lower part of the mounting frame 30 and their bottom surfaces are fixedly connected to the top surface of the machine base 1. The extended ends of the four electric telescopic rods 31 are fixedly connected to the bottom surface of a support plate 32.

[0024] Furthermore, a servo motor 33 is fixedly connected to the bottom center of the support plate 32, and the output end of the servo motor 33 is fixedly connected to the bottom surface of the base plate 34. The base plate 34 is disposed on the top surface of the support plate 32 and a limiting groove 35 is formed on the top surface.

[0025] It should be noted that the extended end of the servo motor 33 extends from the inner wall of the bottom surface of the support plate 32 to its top surface. The servo motor 33 drives the base plate 34 to rotate. The bottom surface of the base plate 34 is equipped with balls to reduce resistance and share the weight. The balls are arranged in a ring array and contact the top surface of the support plate 32.

[0026] Furthermore, the mounting assembly 4 also includes fixing blocks 42 and fixing bolts 43. The fixing blocks 42 are four in a rectangular array and fixedly installed on the bottom surface of the mounting plate 41. The fixing bolts 43 are symmetrically installed on the top surface of the mounting plate 41.

[0027] Furthermore, the insertion block 45 is machined into the inner wall of the slot plate 44 and is fixed by the fixing block 42 and the fixing bolt 43. The slot plate 44 is fixedly connected to the mounting plate 41 by the fixing block 42 and the fixing bolt 43.

[0028] The residual lubricating oil or cooling oil on the aluminum plate surface forms a lubricating film on the surface of the insertion block 45, reducing frictional resistance and ensuring that the insertion block 45 does not get stuck. After punching, the punch resets, and the insertion block 45 automatically detaches from the aluminum plate due to its smooth surface and the effect of the oil film, without sticking or scratching. If other angle holes need to be processed, the controller starts the servo motor 33, which drives the base plate 34 to rotate through its output end. The ball bearings in the annular array on the bottom surface of the base plate 34 contact the top surface of the support plate 32, reducing rotational resistance and dispersing the weight of the aluminum plate. The controller automatically triggers the laser positioning instrument to check the hole position. After confirming that it is correct, step 5 is repeated to complete the remaining punching. After processing, the controller drives the electric telescopic rod 31 to descend to the lowest position to release the aluminum plate. The aluminum plate is removed manually or by a robotic arm from the limiting groove 35 to check the hole position accuracy and surface quality. The first guide block 21 and the second guide block 23 return to the zero position, the punch of the punching device 24 resets, and the servo motor 33 drives the base plate 34 back to the zero position, ready for the next processing.

[0029] The working principle and usage process of this utility model are as follows: Start the controller and input the parameters of the heat dissipation aluminum plate through the human-machine interface: thickness, heat dissipation fin spacing, punching hole diameter, hole layout and processing quantity.

[0030] The controller automatically calculates the height of the electric telescopic pole 31, the movement trajectory of the first guide block 21 and the second guide block 23, and presets the rotation angle of the servo motor 33.

[0031] Insertion block 45 matching and installation: Based on the input heat sink fin spacing parameters, select the corresponding bottom-side design of the insertion block 45 from the tool library. Insert the insertion block 45 into the inner wall of the slot plate 44 and lock it in place using the fixing block 42 and fixing bolt 43, ensuring that the insertion block 45 is not loose. Confirm that the pre-drilled hole of the insertion block 45 is aligned with the target punching position of the aluminum plate.

[0032] Aluminum plate clamping and anti-displacement fixing: Place the aluminum plate with heat dissipation fins flat on the top surface of the base plate 34, so that the heat dissipation fins are embedded in the limiting groove 35 on the surface of the base plate 34. The aluminum plate is naturally attached by the side wall of the limiting groove 35 or by gravity, ensuring that there is no displacement in the horizontal direction.

[0033] Start the fine adjustment of the first guide block 21 and the second guide block 23 to align the center of the punch with the first punch position of the aluminum plate.

[0034] Punching and Deformation Prevention Control: The punching equipment 24 is started to punch holes; the controller controls the electric telescopic rod 31 to rise, and the insertion block 45 is simultaneously embedded in the area around the hole. Its hard surface and the contact surface of the aluminum plate form a local rigid support to disperse the punching stress.

[0035] During the punching process, the lubricating oil or cooling oil remaining on the surface of the aluminum plate forms a lubricating film on the surface of the insertion block 45, reducing frictional resistance and ensuring that the insertion block 45 does not get stuck. After punching is completed, the punch is reset, and the insertion block 45 automatically detaches from the aluminum plate due to the smooth surface and the effect of the oil film, without sticking or scratching.

[0036] Multi-angle machining: If other angle holes need to be machined, the controller starts the servo motor 33, which drives the base plate 34 to rotate through its output end. The ball bearings in the annular array on the bottom surface of the base plate 34 contact the top surface of the support plate 32, reducing rotational resistance and dispersing the weight of the aluminum plate.

[0037] After the hole is rotated into position, the controller automatically triggers the laser positioning instrument to check the hole position. Once confirmed to be correct, step 5 is repeated to complete the remaining punching.

[0038] Unloading and Equipment Reset: After processing, the controller drives the electric telescopic rod 31 to descend to the lowest position, releasing the aluminum plate from its fixation. The aluminum plate is then manually or via a robotic arm removed from the limiting groove 35 to check the hole accuracy and surface quality. The first guide block 21 and the second guide block 23 return to their zero positions, the punch of the drilling equipment 24 resets, and the servo motor 33 drives the base plate 34 back to its zero position, preparing for the next processing cycle.
