[0006] Optionally, there are two punching blocks, which are mirror-imaged, and there are two sliders, which are mirror-imaged. The two punching blocks can punch downwards at the same time and force the two sliders to slide toward each other synchronously.

[0007] Optionally, a pressing plate is further included, which is slidably arranged on the base along a vertical direction, and the two punching blocks are fixed at the left and right ends of the pressing plate.

[0008] Optionally, a guide column extending in a vertical direction is provided on the base, the pressure plate is sleeved on the guide column, and the guide column is configured to provide guidance for the sliding of the pressure plate.

[0009] Optionally, a first compression spring is provided between the middle portion of the pressure plate and the base.

[0010] Optionally, the limiting insert is detachably mounted on the base, and the base is provided with a loading channel extending in a front-to-rear direction, and the radiator can slide onto the base along the loading channel.

[0015] During processing, the radiator to be punched can be placed on the base. Initially, the slider is in the initial position. During the downward punching process of the punching block, the punching block will gradually move downward until the first inclined surface fits the second inclined surface. At this time, the punching block that continues to punch downward will push the slider to move horizontally to the punching position. Since the downward punching speed of the punching block is often very fast, the horizontal movement speed of the slider will also be very fast, which enables the punching rod on the slider to punch the heat sink to be punched on the radiator. By setting a limiting tooth between the heat sink to be punched and the heat sink adjacent to the heat sink to be punched, a supporting force can be provided for the heat sink, so that the impact force of the punching rod will not damage the heat sink.

[0033] like Figures 1 to 3 As shown, the present invention provides a heat sink 200 punching device, including a base 100, a punching block 310, a slider 400 and a limiting insert 600.

[0034] The base 100 can support the radiator 200 and position the radiator 200. The stamping block 310 is slidably arranged on the base 100 in the vertical direction. The lower portion of the stamping block 310 is provided with a first inclined surface 311. The slider 400 is provided on the base 100 and can slide between the initial position and the stamping position in the horizontal direction. The slider 400 is provided with a second inclined surface 411. The first inclined surface 311 and the second inclined surface 411 are parallel to each other. The slider 400 has a horizontally arranged stamping rod 500. The stamping rod 500 is provided with a second inclined surface 411. The position of 0 corresponds to the position of the hole to be punched on the radiator 200, the limiting insert 600 is inserted between the heat sink 210 to be punched and another heat sink 210 adjacent to the heat sink 210 to be punched on the radiator 200, and an avoidance hole 610 is opened on the limiting insert 600. The avoidance hole 610 is coaxially arranged with the punching rod 500. When the punching block 310 punches downward, the punching block 310 can push the slider 400 to slide from the initial position to the punching position through the cooperation of the first inclined surface 311 and the second inclined surface 411.

[0035] It is understood that during processing, the heat sink 200 to be punched can be placed on the base 100. Initially, the slider 400 is located at Figure 2 As shown in the initial position, during the downward pressing process of the punching block 310, the punching block 310 will gradually move downward until the first inclined surface 311 is in contact with the second inclined surface 411. At this time, the punching block 310 that continues to press downward will push the slider 400 to move horizontally to the position shown in the initial position. Figure 3 In the punching position shown, since the downward punching speed of the punching block 310 is often very fast, the horizontal movement speed of the slider 400 is also very fast, which enables the punching rod 500 on the slider 400 to punch the heat sink 210 to be punched on the radiator 200. By providing a limiting insert 600 between the heat sink 210 to be punched and another heat sink 210 adjacent to the heat sink 210 to be punched, a supporting force is provided for the heat sink 210, so that the impact force of the punching rod 500 will not damage the heat sink 210. The present invention can punch the heat sink 210 while ensuring the quality of the radiator 200, thereby improving product quality and punching efficiency.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, two stamping blocks 310 are provided, and the two stamping blocks 310 are mirror-set, and two sliders 400 are provided, and the two sliders 400 are mirror-set. The two stamping blocks 310 can punch downward at the same time and force the two sliders 400 to slide toward each other synchronously, and punching can be achieved on the left and right sides of the radiator 200 at the same time. The two sliders 400 sliding toward each other at the same time can improve the overall operating stability of the punching equipment of the present invention and prevent uneven force on the equipment caused by single-sided punching.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a pressing plate 300 is further included. The pressing plate 300 is vertically slidably disposed on the base 100, and two punching blocks 310 are fixedly disposed on the left and right ends of the pressing plate 300. The movement of the pressing plate 300 can drive the two punching blocks 310 to move up and down synchronously. Specifically, the up and down movement of the pressing plate 300 can be achieved by a mechanism such as a cylinder or a cam.

[0038] Reference Figure 2 and Figure 3 In some embodiments of the present invention, a guide column 110 extending in a vertical direction is provided on the base 100, and the pressure plate 300 is sleeved on the guide column 110. The guide column 110 is configured to provide guidance for the sliding of the pressure plate 300. Specifically, the guide column 110 can be designed to be multiple, and the multiple guide columns 110 can be arrayed in a horizontal plane.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a first compression spring 700 is provided between the middle of the pressure plate 300 and the base 100, and the two ends of the first compression spring 700 can be connected to the pressure plate 300 and the base 100 respectively, so that when the pressure plate 300 is not subjected to a downward force, it can move upward and return to its original position.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the limiting insert 600 is detachably mounted on the base 100, so that the corresponding limiting insert 600 can be replaced when processing different models of heat sinks 200. In addition, the base 100 is provided with a loading channel 120 extending in the front-to-back direction. The heat sink 200 can slide into the base 100 along the loading channel 120. The limiting insert 600 can extend in the front-to-back direction. As the heat sink 200 enters the loading channel 120 in the front-to-back direction, the limiting insert 600 can be inserted between the corresponding two heat sinks 210.

[0041] In some embodiments of the present invention, a limiting plate (not shown) is further included. The limiting plate is detachably mounted on the base 100. The limiting plate is used to fix the position of the heat sink 200 relative to the base 100 after being connected to the base 100. Specifically, after the heat sink 200 enters the base 100 along the loading channel 120 and is placed in place, the limiting plate can be connected to the base 100 so that the limiting plate restricts the heat sink 200 to a fixed position on the base 100.

[0042] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, the slider 400 includes a main body 410 and a cover plate 420, the second inclined surface 411 is arranged on the main body 410, the cover plate 420 is detachably arranged on one end of the main body 410 facing the limiting tooth 600, and the punching rod 500 is passed through the cover plate 420. When the cover plate 420 is connected to the main body 410, the position of the punching rod 500 can be limited between the cover plate 420 and the main body 410. The above structure can facilitate the replacement of the punching rod 500, so that the punching equipment in the present invention can process radiators 200 with different apertures.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a second compression spring 800 is provided between the slider 400 and the base 100. The second compression spring 800 is configured to make the slider 400 always have a tendency to slide toward the initial position. When the stamping block 310 moves upward, the slider 400 can be prompted to return to the initial position under the action of the elastic restoring force of the second compression spring 800, so as to facilitate the next stamping action.

[0044] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
