Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, and in particular to a heat dissipation device for a cold heading forming machine. Background Technology

[0002] Cold heading machines are chipless cold working equipment commonly used for the production of standard parts such as bolts, screws, nuts, and rivets. During the operation of a cold heading machine, a large amount of heat is generated when the punch and die work together to form the product. To improve the heat dissipation effect, existing technologies, such as the utility model patent: a heat dissipation device for a fully automatic cold heading machine (publication number: CN215392312U), disclose a heat dissipation device that can dissipate heat from the cold heading machine. However, this heat dissipation device is not specifically designed for the cold heading machine; that is, it cannot efficiently dissipate heat from the area where the punch and die work together to generate a large amount of heat. The heat dissipation effect needs to be improved.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a heat dissipation device for a cold heading forming machine, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A heat dissipation device for a cold heading forming machine includes a frame, on which an air guide duct and a fan connected to the air guide duct are arranged. A first air outlet duct is horizontally arranged at the end of the air guide duct. A second air outlet duct is slidably inserted at each end of the first air outlet duct. A third air outlet duct with an end-sealed end is slidably inserted at the end of the second air outlet duct. A first air nozzle, a second air nozzle, and a third air nozzle are respectively connected to the first air outlet duct, the second air outlet duct, and the third air outlet duct. Two drive screws extending to both ends of the first air outlet duct are rotatably arranged on the outer wall of the first air outlet duct. The drive screws have a first threaded section and a second threaded section with a lead twice that of the first threaded section. A first drive block and a second drive block are fixedly connected to the second air outlet duct and the third air outlet duct, respectively, and screwed to the first threaded section and the second threaded section.

[0007] Preferably, each of the two drive screws is fixedly connected to a first bevel gear, and an operating handle is rotatably provided on the outer wall of the first air outlet pipe. The end of the operating handle is fixedly connected to a second bevel gear that meshes with the two first bevel gears.

[0008] Preferably, a first sealing ring is provided on the outer wall of the end of the second air outlet pipe that penetrates into the first air outlet pipe, and a second sealing ring is provided on the outer wall of the end of the third air outlet pipe that penetrates into the second air outlet pipe.

[0009] Preferably, the first air outlet, the second air outlet, and the third air outlet are screwed onto the first air outlet pipe, the second air outlet pipe, and the third air outlet pipe, respectively.

[0010] Preferably, the frame is provided with a sliding plate that is longitudinally slidably connected to a motor mounted on the frame, and the air duct and the fan are mounted on the sliding plate.

[0011] Preferably, the frame is provided with two vertical linear guide rails, the sliding plate is fixedly connected to the sliding seat of the linear guide rails, and a transmission screw is rotatably provided on the frame and screwed to the sliding plate, the end of the transmission screw being connected to the motor for transmission.

[0012] Preferably, the lower end of the frame is provided with rollers, and the side end of the frame is provided with a push-pull handle.

[0013] In summary, the beneficial effects of this utility model are as follows: By rotating the drive screw, the first and second drive seats are driven to slide the second and third air outlet pipes relative to the first air outlet pipe. The distance between the first, second, and third air outlets is adjusted to match the distance between the sets of dies in the cold heading machine, and each air outlet is moved above the sets of dies in the cold heading machine. When the cold heading machine is working, the fan pumps cooling airflow through the air duct. The cooling airflow enters the first, second, and third air outlet pipes through the air duct and flows out from the first, second, and third air outlets, blowing towards the sets of dies in the cold heading machine. This removes the heat generated when the punch and die are engaged, achieving a cooling effect. Because each air outlet specifically targets the area where the die and punch are engaged in the cold heading machine during the cooling process, a large amount of heat is removed, resulting in a better cooling effect.

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] As shown in the figure, a heat dissipation device for a cold heading forming machine includes a frame 1. The frame 1 is provided with an air guide pipe 2 and a fan 3 connected to the air guide pipe 2. The end of the air guide pipe 2 is connected to a horizontally arranged first air outlet pipe 4. A second air outlet pipe 5 is slidably inserted through each end of the first air outlet pipe 4. A third air outlet pipe 6 with an end-sealed end is slidably inserted through the end of the second air outlet pipe 5. A first air outlet nozzle 41, a second air outlet nozzle 51, and a third air outlet nozzle 61 are respectively connected to the first air outlet pipe 4, the second air outlet pipe 5, and the third air outlet pipe 6. Two drive screws 42 extending to both ends of the first air outlet pipe 4 are rotatably arranged on the outer wall of the first air outlet pipe 4. The drive screws 42 have a first threaded section 421 and a second threaded section 422 with a lead twice that of the first threaded section 421. A first drive block 52 and a second drive block 62 are respectively fixedly connected to the second air outlet pipe 5 and the third air outlet pipe 6 and screwed to the first threaded section 421 and the second threaded section 422.

[0023] In the above structure, two second air outlet pipes 5 are respectively inserted through and connected to the first air outlet pipe 4, and two third air outlet pipes 6 are respectively inserted through the ends of the two second air outlet pipes 5 and connected to the second outlet branch pipes. One first air outlet 41, two second air outlets 51 and two third air outlets 61 are arranged horizontally. When cooling the cold heading forming machine, the frame 1 is moved to move the first air outlet 41, the second air outlet 51 and the third air outlet 61 to be located on the upper part of each set of dies of the cold heading forming machine. In the cold heading machine, when the punch and die are engaged in the forming process, the fan 3 is activated to pump cooling airflow through the air duct 2. This cooling airflow enters the first air outlet 4 through the air duct 2 and is then distributed to the second air outlet 5 and the third air outlet 6. The airflow is then blown from the first air outlet 41, the second air outlet 51, and the third air outlet 61 towards each set of dies, carrying away the heat generated during the engagement of the punch and die, thus achieving a cooling effect. During the aforementioned cooling process of the cold heading machine, each air outlet... Targeted heat dissipation is implemented in the working areas of each set of dies and punches in the cold heading machine to remove the large amount of heat generated, thus achieving better heat dissipation. To better adapt to the heat dissipation of different cold heading machines, the spacing of each set of dies varies in cold heading machines processing different products. By rotating the drive screw 42, the drive screw 42 drives the first drive block 52 and the second drive block 62 through the screwed engagement of the first threaded section 421 with the first drive block 52 and the second threaded section 422 with the second drive block 62. This drives the second air outlet 5 and the third air outlet 6 to move relative to the first air outlet 4. Since the lead of the second threaded section 422 is twice that of the first threaded section 421, the moving speed of the third air outlet is twice that of the second air outlet 5. This ensures that the spacing between the first air outlet 41 and the second air outlet 51, and between the second air outlet 51 and the third air outlet 61, remains consistent, thereby achieving the adjustment of the spacing of each air outlet to suit the heat dissipation of different cold heading processes, thus providing better applicability.

[0024] Additionally, each of the two drive screws 42 is fixedly connected to a first bevel gear 43. An operating handle 44 is rotatably mounted on the outer wall of the first air outlet pipe 4. A second bevel gear 45, which meshes with the two first bevel gears 43, is fixedly connected to the end of the operating handle 44. By rotating the operating handle 44, the second bevel gear 45 is driven to rotate. The second bevel gear 45, through meshing with the two first bevel gears 43, simultaneously drives the two drive screws 42 to rotate, thereby synchronously driving the second air outlet pipe 5 and the third air outlet pipe 6 located at both ends of the first air outlet pipe 4 to move, making the spacing adjustment of each air outlet more convenient and accurate.

[0025] In addition, a first sealing ring 53 is provided on the outer wall of the end of the second air outlet pipe 5 that penetrates into the first air outlet pipe 4, and a second sealing ring 63 is provided on the outer wall of the end of the third air outlet pipe 6 that penetrates into the second air outlet pipe 5. The first sealing ring 53 and the second sealing ring 63 respectively enhance the sealing between the second air outlet pipe 5 and the first air outlet pipe 4 and between the third air outlet pipe 6 and the second air outlet pipe 5, reduce the loss of heat dissipation airflow and ensure the efficiency of heat dissipation for the cold heading forming machine.

[0026] In addition, the first air outlet 41, the second air outlet 51, and the third air outlet 61 are screwed onto the first air outlet pipe 4, the second air outlet pipe 5, and the third air outlet pipe 6, respectively. The above connection method facilitates the disassembly and assembly of the first air outlet 41, the second air outlet 51, and the third air outlet 61. According to the number of dies of the cold heading forming machine, the number of air outlets can be matched with the number of dies by disassembling and assembling each air outlet. The air outlet of the air outlet pipe where the air outlet is removed is sealed by screwing on a cap, thereby reducing the loss of heat dissipation airflow and ensuring the efficiency of heat dissipation for the cold heading forming machine.

[0027] Additionally, a sliding plate 7, which is longitudinally slidable and connected to a motor 8 mounted on the frame 1, is provided on the frame 1. The air duct 2 and the fan 3 are mounted on the sliding plate 7. Specifically, two vertical linear guide rails 11 are provided on the frame 1. The sliding plate 7 is fixedly connected to the sliding seat of the linear guide rails 11. A transmission screw 12, which is screwed onto the sliding plate 7, is rotatably mounted on the frame 1. The end of the transmission screw 12 is connected to the motor 8. The motor 8 drives the transmission screw 12 to rotate. The transmission screw 12, through its screw connection with the sliding plate 7, drives the sliding plate 7 to slide longitudinally on the linear guide rails 11. The sliding plate 7 drives the air duct 2 and the fan 3 to slide longitudinally, thereby adjusting the horizontal height of each air outlet to adapt to cold heading forming machines of different sizes. This ensures that each air outlet is accurately positioned above each set of dies in the cold heading forming machine, thus guaranteeing the heat dissipation effect of the cold heading forming machine and providing better applicability.

[0028] Additionally, the lower end of the frame 1 is provided with a roller 13, which is a locking roller 13. The side end of the frame 1 is provided with a push-pull handle 14. By using the push-pull handle 14 in conjunction with the roller 13, the heat dissipation device can be moved more conveniently to adjust the position of each air outlet and the die of the cold heading forming machine, ensuring the heat dissipation effect of the cold heading forming machine and facilitating the use of this heat dissipation device.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
