[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a heat dissipation fin punching device, including a workbench 1 and a connecting belt 17. A fixed frame 6 is fixedly connected to the front side of the top of the workbench 1. A servo motor 16 is fixedly connected to the front side of the fixed frame 6. The output end of the servo motor 16 penetrates through the fixed frame 6 and is fixedly connected to a driving pulley 15. The left end of the rear side of the fixed frame 6 is rotatably connected to a driven pulley one 19. The middle upper part of the rear side of the fixed frame 6 is rotatably connected to a driven pulley two 21. The driving pulley 15 is respectively in transmission connection with the driven pulley one 19 and the driven pulley two 21 through the connecting belt 17. A worm 22 is fixedly connected to the rear sides of both the driving pulley 15 and the driven pulley one 19. A worm gear 14 is meshed and connected to the right side of the worm 22. Threaded rods 18 are fixedly connected to both the upper and lower sides of the outer wall of the worm gear 14. A movable plate 20 is threadedly connected to the outer side of the threaded rod 18. A clamping plate 23 is fixedly connected to the rear side of the movable plate 20. A cooling mechanism 2 is arranged on the top of the workbench 1, and the cooling mechanism 2 is used for cooling the punching head and the punched part; A slider 3 is fixedly connected to the outer side of the movable plate 20. A limiting groove 12 is formed on the outer wall of the fixed frame 6, and the slider 3 is slidably connected to the limiting groove 12; An installation frame 13 is installed on the rear side of the top of the workbench 1, and a punching device 10 is installed on the top of the installation frame 13; A control button board 9 is installed in the middle upper part of the front side of the installation frame 13, and the control button board 9 is electrically connected to the punching device 10;

[0031] Specifically, when the servo motor 16 is started, it drives the driving pulley 15 to rotate; enabling the worm 22 to rotate synchronously; the meshing transmission design between the worm 22 and the worm gear 14 not only ensures the transmission efficiency, but also makes the entire transmission process more stable and reliable; the rotation of the worm gear 14 further drives the rotation of the threaded rod 18; the rotation of the threaded rod 18 is the key to driving the lifting movement of the movable plate 20; the movable plate 20 is driven by the threaded rod 18 to achieve precise lifting movement; at the same time, the movement of the movable plate 20 drives the slider 3 to slide in the limiting groove 12; the design of the limiting groove 12 cleverly plans the movement track of the slider 3, ensuring the stability and accuracy of the slider 3 during movement; as the movable plate 20 moves up and down, the clamping plate 23 also moves synchronously; it can firmly clamp both ends of the heat dissipation fin; this clamping method can not only effectively avoid the situation that both ends of the heat dissipation fin are warped due to strong punching pressure during the punching process, but also prevent the heat dissipation fin from being deformed; when the heat dissipation fin is clamped and fixed, the punching device 10 can be controlled to start through the control button board 9; the punching device 10 adopts advanced punching technology, which can ensure the punching accuracy and efficiency.

[0032] Refer to Figure 1 , Figure 2 and Figure 3, the cooling mechanism 2 includes a gear 201. The front side of the gear 201 is fixedly connected to the rear side of the second driven pulley 21. The upper rear end of the fixed frame 6 is fixedly connected with a slide rail 203. A sawtooth rack 202 is slidably connected inside the slide rail 203. The gear 201 is meshed with the sawtooth rack 202. The rear side of the sawtooth rack 202 is fixedly connected with a hollow tube 204. A plurality of atomizing nozzles 205 are equidistantly communicated with the rear side of the hollow tube 204. A connecting pipe 11 is communicated with the top of the hollow tube 204. A valve 7 is installed on the front side of the outer wall of the connecting pipe 11.

[0033] Specifically, when the punching operation is carried out, the valve 7 will be opened and connected to the external water source pipeline through the connecting pipe 11. At this time, the continuous water source will flow into the hollow tube 204 through the connecting pipe 11. At the same time, the atomizing nozzles 205 will be started synchronously to atomize and evenly spray the water source flowing into the hollow tube 204. The rotation of the second driven pulley 21 will drive the gear 201 to rotate synchronously. The precise meshing transmission between the gear 201 and the sawtooth rack 202 ensures the stable sliding of the sawtooth rack 202 in the slide rail 203. In this way, the moving track of the sawtooth rack 202 is accurately planned, so that it can move reciprocally along the predetermined path. As the sawtooth rack 202 moves, the hollow tube 204 and the atomizing nozzles 205 connected to it will also move synchronously. This movement not only increases the cooling coverage area, but also enables the atomizing nozzles 205 to spray water mist more evenly. Through this design, the comprehensive cooling of the stamping parts and the stamping head is successfully realized, the temperature is effectively reduced, and the service life of the equipment is thus extended. The model of the servo motor 16 is Parker SMH. The model of the punching equipment 10 is Amada AE2510NT.

[0034] Refer to Figure 1 , a limiting ring 8 is fixedly connected to the middle of the top wall of the fixed frame 6. The outside of the connecting pipe 11 is arranged inside the limiting ring 8. A stabilizing frame 4 is installed at the bottom of the workbench 1. Bottom pads 5 are installed at the four corners of the bottom of the stabilizing frame 4.

[0035] Specifically, the position of the connecting pipe 11 is limited by the limiting ring 8, and the cooperation between the stabilizing frame 4 and the bottom pads 5 increases the stability of the equipment during operation.

[0036] Working principle: When using the punching device for heat dissipation fins, place the heat dissipation fins between the two clamping plates 23. Turn on the servo motor 16 to drive the active pulley 15 to rotate. The rotation of the active pulley 15 drives the worm 22 to rotate synchronously, meshing with the worm gear 14 for transmission, thereby driving the threaded rod 18 to rotate synchronously. The rotation of the threaded rod 18 drives the movable plate 20 to move up and down. The movement of the movable plate 20 drives the slider 3 to slide in the limit groove 12, planning the movement track of the slider 3. Through the movement of the movable plate 20, the clamping plates 23 move synchronously, thereby clamping and fixing the two ends of the heat dissipation fins. Control the punching device 10 to start through the control button board 9 to perform the punching process on the heat dissipation fins;

[0037] And during the punching process of the heat dissipation fins, open the valve 7 to connect to the external water source pipeline through the connecting pipe 11. The water source is discharged into the hollow pipe 204 through the connecting pipe 11. At the same time, turn on the atomizing nozzle 205 to atomize and spray the water source. The rotation of the driven pulley two 21 drives the gear 201 to rotate synchronously. The rotation of the gear 201 meshes with the saw rack 202 for transmission, thereby driving the saw rack 202 to slide in the slide rail 203, planning the movement track of the saw rack 202. Through the movement of the saw rack 202, the hollow pipe 204 and the atomizing nozzle 205 move synchronously, thereby increasing the cooling range.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
