Technical Field

[0001] This utility model relates to the field of heat sink stamping technology, and more specifically, to a heat sink stamping die. Background Technology

[0002] In modern industrial fields such as electronics, communications, and automobiles, heat dissipation performance is one of the key factors ensuring the stable operation of equipment. As a core heat dissipation component, the structural design and manufacturing precision of heat sinks directly affect heat dissipation efficiency. With the miniaturization and high power of electronic devices, increasingly higher requirements are being placed on the structural complexity, dimensional accuracy, and production efficiency of heat sinks.

[0003] The existing publication number CN112605267A discloses a brake pad stamping die with good heat dissipation. The die includes a base plate, with supporting columns fixedly connected to the upper sides of both sides. A drive mechanism is fixedly connected to the lower part of the left supporting column, and a sector gear handle is rotatably connected to the drive mechanism. A fixed block is fixedly connected to the upper part of the middle of the base plate, and a sliding rack is slidably connected to the middle of the fixed block. A mounting bracket is fixedly connected to the upper end of the sliding rack. Fixed plates are fixedly connected to the lower sides of both sides of the mounting bracket. An electric push rod is fixedly connected to the upper part of one side of the fixed plate, and a swing plate is rotatably connected to the upper end of the electric push rod. The lower side of the swing plate is rotatably connected to a column fixedly connected to the upper part of the fixed plate. A connecting shaft is fixedly connected to the upper part of the swing plate. The electric push rod drives the swing plate to swing, which in turn drives the connecting shaft to swing, which in turn drives the cooler to swing, thereby fully cooling the interior of the mounting bracket and effectively avoiding a series of problems caused by excessive temperature. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: The existing heat sink stamping die has insufficient guiding mechanism precision, which can easily lead to misalignment of the upper and lower dies during heat sink stamping. This not only affects the dimensional accuracy of the product, but also aggravates die wear and shortens its service life. Therefore, a heat sink stamping die is proposed to address the above problems. Utility Model Content

[0023] Specifically: When punching holes in the heat sink, the heat sink is first placed on the top of the base plate 1 and then fixed by the fixing component 17. Then, the motor is started to make the slider 13 slide in the middle of the slide groove 12. At this time, the first support column 14 drives the mounting bracket 15 to move towards the base plate 1. Then, the punching head 16 passes through the heat sink to complete the punching.

[0024] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5As shown below, see details: In a preferred embodiment, the fixing assembly 17 includes a fixing block 2. When fixing the heat sink, the electric push rod 21 is first controlled to extend and retract. At this time, the electric push rod 21 pushes the top block 22 to move, and the end of the limiting rod 24 first contacts the surface of the heat sink. The electric push rod 21 is installed on the side wall of the fixing block 2. At this time, as the electric push rod 21 is extended and retracted, the spring 23 is squeezed and deformed, generating elastic potential energy. The end of the electric push rod 21 is fixed to the top block 22. The limiting rod 24 that does not contact the heat sink remains in its original position. Multiple springs 23 are fixed to the inner side wall of the top block 22. The end of the spring 23 is fixed to the limiting rod 24. The limiting rod 24 slides in the reserved hole in the side wall of the top block 22. The top plate 25 is fixed to the top of the bottom plate 1. At this time, the spring 23 can push the limiting rod 24 to fit tightly against the heat sink, and at the same time, the multiple limiting rods 24 limit the heat sink, pushing the other side of the heat sink to contact the top plate 25 for fixing.

[0025] In a preferred embodiment, square plates 3 are fixed to both sides of the top block 22; then the clamping plate 32 is slidable in the middle of the groove 31; the square plate 3 has a groove 31 in the middle; the clamping plate 32 is slidably connected in the middle of the groove 31; until the clamping plate 32 contacts the surface of the heat sink, the heat sink can be longitudinally fixed to prevent it from shifting during stamping.

[0026] In a preferred embodiment, a first rubber pad 4 is fixedly connected to the end of the limiting rod 24; when the limiting rod 24 contacts the heat sink, the first rubber pad 4 is squeezed and deformed, tightly adhering to the surface of the workpiece; a second rubber pad 41 is fixedly connected to the side wall of the clamping plate 32; by increasing the contact area and friction, the heat sink is prevented from slipping.

[0027] In a preferred embodiment, a second support column 5 is fixedly connected to the bottom of the mounting bracket 15; firstly, the end of the water supply pipe 53 is connected to the water pump, at which time the water pump can transmit liquid to the middle of the spray ring 51 through the water supply pipe 53; the spray ring 51 is installed at the bottom of the second support column 5; multiple spray holes 52 are opened at the bottom of the spray ring 51; then the liquid can be sprayed out from the spray holes 52; the top of the second support column 5 is fixedly connected to the water supply pipe 53; the water supply pipe 53 is connected to the middle of the spray ring 51; at this time, the sprayed liquid can quickly carry away the large amount of heat generated by friction during the stamping process, avoid the stamping head 16 from decreasing in hardness and aggravating wear due to high temperature, and effectively extend its service life.

[0028] In a preferred embodiment, a high-pressure nozzle 6 is fixedly connected to the bottom of the spray hole 52; the spray hole 52 sprays liquid to the middle of the high-pressure nozzle 6; the high-pressure nozzle 6 is connected to the middle of the spray ring 51; the punch head 16 is located in the middle of the spray ring 51; at this time, the flow guide cavity in the middle of the high-pressure nozzle 6 guides the water to the constricted flow channel of the nozzle, and the water flow velocity increases sharply as the cross-sectional area decreases, forming a high-speed jet that is sprayed out onto the punch head 16.

[0029] In a preferred embodiment, a square groove 7 is provided on the top of the base plate 1; a collection box 71 is installed at the bottom of the square groove 7; the collection box 71 is located at the bottom of the base plate 1; waste and liquid generated during stamping are discharged from the square groove 7 to the middle of the collection box 71.

[0030] In a preferred embodiment, the side wall of the collection box 71 is provided with a concave groove 8; when the middle of the collection box 71 needs to be cleaned, the protruding strip 81 is pushed and then slides in the middle of the concave groove 8, so that the collection box 71 can be removed; the protruding strip 81 is slidably connected in the middle of the concave groove 8; the protruding strip 81 is fixedly connected to the bottom of the base plate 1; otherwise, the collection box 71 can be installed.

[0031] In this embodiment, the electric actuator 21, the stamping head 16, etc. are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here.

[0032] The working process of this utility model is as follows: When the heat sink is to be punched and opened, the heat sink is first placed on the top of the base plate 1, and the electric push rod 21 is controlled to extend and retract. At this time, the electric push rod 21 pushes the top block 22 to move. The end of the limiting rod 24 first contacts the surface of the heat sink. As the electric push rod 21 extends and retracts, the first rubber pad 4 is squeezed and deformed, tightly adhering to the surface of the workpiece. At the same time, the spring 23 is squeezed and deformed to generate elastic potential energy. The limiting rod 24 that does not contact the heat sink remains in its original position. Multiple limiting rods 24 limit the heat sink, push the other side of the heat sink to contact the top plate 25 for fixation, and then make the clamping plate 32 slide in the middle of the groove 31 until the clamping plate 32 contacts the surface of the heat sink. The heat sink can be longitudinally fixed to prevent it from shifting during punching, thus completing the fixation.

[0033] Then connect the end of the water supply pipe 53 to the water pump. At this time, the water pump can transmit the liquid to the middle of the spray ring 51 through the water supply pipe 53. Then the liquid can be sprayed from the spray hole 52 to the middle of the high pressure nozzle 6. At this time, the flow guide cavity in the middle of the high pressure nozzle 6 guides the flow to the constricted flow channel of the nozzle. The water flow velocity increases sharply as the cross-sectional area decreases, forming a high-speed jet that sprays out onto the stamping head 16. The sprayed liquid can quickly carry away a large amount of heat generated by friction during the stamping process. Then the motor is started to make the slider 13 slide in the middle of the slide groove 12. At this time, the first support column 14 drives the mounting bracket 15 to move towards the base plate 1. Then the stamping head 16 passes through the heat sink and completes the stamping. The waste and liquid generated during the stamping are discharged from the square groove 7 to the middle of the collection box 71. When the middle of the collection box 71 needs to be cleaned, push the protrusion 81. At this time, the protrusion 81 slides in the middle of the concave groove 8, and the collection box 71 can be removed. Conversely, the collection box 71 can be installed. The above is the working principle of this heat sink stamping die.
