[0002] Aluminum-magnesium alloy heat sinks are components used for heat dissipation, commonly found in electronic devices, computer hardware, LED lighting, and other fields. Due to their excellent thermal conductivity, lightweight nature, and corrosion resistance, aluminum-magnesium alloy heat sinks are widely used in various fields and are an ideal choice for efficient heat dissipation.

[0003] Currently, existing aluminum-magnesium alloy heat sinks are generally bent manually or semi-automatically, resulting in slow bending speeds. This not only severely affects the processing efficiency of aluminum-magnesium alloy heat sinks but also makes it difficult to guarantee the quality of finished products. Furthermore, it poses a safety hazard of accidental injury from the equipment. Therefore, it is necessary to design a lightweight, rapid bending device for aluminum-magnesium alloy heat sinks. Summary of the Invention

[0004] To address the aforementioned issues, and to resolve the problem that existing aluminum-magnesium alloy heat sinks are typically bent manually or semi-automatically, resulting in slow bending speeds, which severely impacts processing efficiency and quality, and poses safety hazards such as accidental injury, this invention provides a lightweight, rapid bending device for aluminum-magnesium alloy heat sinks. This device effectively enables rapid and automatic bending of the heat sink, allowing it to move quickly in and out of the bending area before and after bending. This not only ensures product quality but also eliminates the safety hazards associated with manual handling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight aluminum-magnesium alloy heat sink rapid bending device, comprising a support assembly, the support assembly being used for a linear drive assembly and a linear pressing assembly, the linear drive assembly being used to drive a heat sink limiting assembly to move linearly to a position directly below the linear pressing assembly, the heat sink limiting assembly being used to receive and limit the aluminum-magnesium alloy heat sink to be bent, and the linear pressing assembly being used to perform a pressing bending operation on the aluminum-magnesium alloy heat sink to be bent received by the heat sink limiting assembly.

[0006] The aforementioned lightweight aluminum-magnesium alloy heat sink quick bending device includes a support assembly comprising a support plate, one end of a support rod being provided on the outer wall of the bottom surface of the support plate, and the other end of the support rod being connected to a base.

[0007] The aforementioned lightweight aluminum-magnesium alloy heat sink quick bending device includes a linear drive assembly comprising a support base, the support base being detachably connected to the upper surface of a support plate, an electric cylinder being detachably connected to the upper surface of the support base, one end of a pneumatic telescopic rod being slidably connected to the inner wall of the electric cylinder, and a slider being detachably connected to the other end of the pneumatic telescopic rod, a slide rail being detachably connected to the upper surface of the support base, the inner wall of the slider being slidably connected to the outer wall of the slide rail, and an auxiliary support block being provided on the upper surface of the support base.

[0008] The aforementioned lightweight aluminum-magnesium alloy heat sink quick bending device includes a heat sink limiting component comprising a limiting plate, wherein the bottom outer wall of the limiting plate is detachably connected to the upper surface of the slider, and a limiting groove is formed on the upper surface of the limiting plate, the limiting groove being used to limit the aluminum-magnesium alloy heat sink to be bent.

[0009] The aforementioned lightweight aluminum-magnesium alloy heat sink quick bending device includes a linear pressing assembly comprising a vertical rod, one end of which is detachably connected to the upper surface of a support plate, and the other end of which is detachably connected to an end plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes an electric cylinder to drive a pneumatic telescopic rod to extend and slide, thereby causing a slider to slide linearly along a slide rail. This, in turn, causes a limiting plate to slide linearly to a position below the pressure plate. Then, an electric hydraulic cylinder drives a hydraulic telescopic rod to extend and slide, causing the pressure plate to move linearly downwards. This allows the outer wall of the bottom surface of the pressure plate to fit against the upper surface of the limiting plate, enabling the aluminum-magnesium alloy heat sink to be bent into a finished aluminum-magnesium alloy heat sink inside the limiting groove. Simultaneously, the sliding action of the sliding hole along the vertical rod ensures the stability of the pressure plate's downward pressure. The auxiliary support block provides longitudinal support to the limiting plate, preventing damage between the slider and the slide rail. This device effectively enables rapid and automatic bending of aluminum-magnesium alloy heat sinks, allowing the heat sink to move quickly in and out of the bending area before and after bending. This not only ensures the quality of the finished heat sink but also eliminates the safety hazards associated with manual handling of heat sinks. Attached Figure Description

Example

[0023] Depend on Figures 1-5 This invention discloses a lightweight aluminum-magnesium alloy heat sink rapid bending device, comprising a support assembly 1. The support assembly 1 is used for a linear drive assembly 2 and a linear pressing assembly 4. The linear drive assembly 2 drives a heat sink limiting assembly 3 to move linearly to a position directly below the linear pressing assembly 4. The heat sink limiting assembly 3 is used to receive and limit the aluminum-magnesium alloy heat sink to be bent. The linear pressing assembly 4 is used to press down and bend the aluminum-magnesium alloy heat sink to be bent received by the heat sink limiting assembly 3. This invention achieves the function of rapid and automatic bending of the aluminum-magnesium alloy heat sink to be bent, and the heat sink can quickly move in and out of the bending area before and after bending. This not only ensures the product quality of the finished heat sink, but also eliminates the safety hazards of manual handling of heat sinks.

[0024] Specifically, the support assembly 1 includes a support plate 101, one end of a support rod 102 is provided on the outer wall of the bottom surface of the support plate 101, and the other end of the support rod 102 is connected to a base 103. The support plate 101 can provide stable support for the linear drive assembly 2, the heat sink limiting assembly 3 and the linear pressing assembly 4.

[0025] Specifically, the linear drive assembly 2 includes a support base 201, which is detachably connected to the upper surface of the support plate 101. An electric cylinder 202 is detachably connected to the upper surface of the support base 201. One end of a pneumatic telescopic rod 203 is slidably connected to the inner wall of the electric cylinder 202, and the other end of the pneumatic telescopic rod 203 is detachably connected to a slider 205. A slide rail 204 is detachably connected to the upper surface of the support base 201. The inner wall of the slider 205 is slidably connected to the outer wall of the slide rail 204. An auxiliary support block 206 is also provided on the upper surface of the support base 201. By operating the electric cylinder 202, the pneumatic telescopic rod 203 is extended and slid, thereby driving the slider 205 to slide linearly along the slide rail 204, which in turn drives the limiting plate 301 to slide linearly to the position below the pressure plate 405.

[0026] Specifically, the heat sink limiting assembly 3 includes a limiting plate 301. The bottom outer wall of the limiting plate 301 is detachably connected to the upper surface of the slider 205. A limiting groove 302 is provided on the upper surface of the limiting plate 301. The limiting groove 302 is used to limit the aluminum-magnesium alloy heat sink to be bent. The limiting groove 302 can stably limit the aluminum-magnesium alloy heat sink.

[0027] Specifically, the linear pressing assembly 4 includes a vertical rod 401. One end of the vertical rod 401 is detachably connected to the upper surface of the support plate 101, and the other end of the vertical rod 401 is detachably connected to an end plate 402. An electric hydraulic cylinder 403 is detachably connected to the upper surface of the end plate 402. One end of a hydraulic telescopic rod 404 is slidably connected to the inner wall of the electric hydraulic cylinder 403, and the other end of the hydraulic telescopic rod 404 is detachably connected to a pressure plate 405. A sliding hole 406 is provided on the upper surface of the pressure plate 405. The inner wall of the sliding hole 406 is slidably connected to the outer wall of the vertical rod 401. The operation of the electric hydraulic cylinder 403 drives the hydraulic telescopic rod 404 to extend and slide, thereby driving the pressure plate 405 to move linearly downward. This allows the outer wall of the bottom surface of the pressure plate 405 to fit against the upper surface of the limiting plate 301, so that the aluminum-magnesium alloy heat sink to be bent inside the limiting groove 302 can be bent into a finished aluminum-magnesium alloy heat sink.

[0028] Specifically, there are two slide rails 204, and the two slide rails 204 are symmetrically distributed on the upper surface of the support plate 101. The number of slide rails 204 makes the linear movement of the slider 205 more stable.

[0029] Specifically, there are multiple limiting grooves 302, and the multiple limiting grooves 302 are evenly distributed on the upper surface of the limiting plate 301. The multiple limiting grooves 302 enable the pressure plate 405 to mass-produce multiple aluminum-magnesium alloy heat sinks in a single movement.

[0030] Specifically, there are four vertical rods 401, and the four vertical rods 401 are symmetrically distributed on the upper surface of the support plate 101. The stability of the pressure plate 405 is ensured by the sliding action of the sliding hole 406 along the vertical rods 401.

[0031] In use, the electric cylinder 202 first drives the pneumatic telescopic rod 203 to extend and slide, thereby causing the slider 205 to slide linearly along the slide rail 204. This, in turn, causes the limiting plate 301 to slide linearly to a position below the pressure plate 405. Then, the electric hydraulic cylinder 403 drives the hydraulic telescopic rod 404 to extend and slide, thereby causing the pressure plate 405 to move linearly downward. This allows the outer wall of the bottom surface of the pressure plate 405 to fit against the upper surface of the limiting plate 301, thus allowing the aluminum-magnesium alloy heat sink inside the limiting groove 302 to be bent into a finished aluminum alloy heat sink. The magnesium alloy heat sink, along with the sliding hole 406 sliding along the vertical rod 401, ensures the stability of the pressure plate 405 pressing down. The auxiliary support block 206 provides longitudinal support to the limiting plate 301, thus preventing damage between the slider 205 and the slide rail 204. This effectively enables the device to quickly and automatically bend the aluminum-magnesium alloy heat sink, and the heat sink can quickly move in and out of the bending area before and after bending. This not only ensures the product quality of the finished heat sink, but also eliminates the safety hazards of manual handling of the heat sink.
