Description

Technical Field

[0001] This utility model relates to a heat sink processing equipment, and more specifically, it relates to a punch press for processing heat sinks of heat dissipation modules. Background Technology

[0002] A punch press for heat sink processing is a type of mechanical equipment specifically used to manufacture heat sinks (typically used for heat dissipation of electronic devices such as CPUs and GPUs in computers).

[0003] During the production process, the punch press needs to perform frequent stamping operations. Each stamping operation generates a certain amount of heat, which gradually accumulates, causing the punch temperature to rise. Overheating will cause the surface hardness of the punch to decrease, thereby accelerating its wear process and affecting the service life of the punch.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a punch press for processing heat sinks of heat dissipation modules, which aims to solve the technical problem of accelerated wear due to increased punch temperature.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punch press for processing heat sinks of a heat dissipation module, comprising a worktable and a lower die, the lower die being fixed to the upper end of the worktable, a fixed frame being fixedly installed at the upper end of the worktable, a hydraulic cylinder being fixedly installed at the top of the fixed frame, a movable frame being fixedly installed at the output end of the hydraulic cylinder, an upper die being fixedly installed at the lower end of the movable frame, a punch being fixedly installed at the lower middle side of the upper die, a cooling channel being U-shaped inside the punch, a liquid storage tank and a liquid pump being fixedly installed at the upper left side of the upper die, the liquid pump being internally connected to the liquid storage tank, an outlet pipe being fixedly installed at the output end of the liquid pump, the outlet of the outlet pipe being connected to the inlet of the cooling channel, a collection tank being placed at the upper right side of the upper die, a drain pipe being fixedly installed on the outer surface of the collection tank, the drain pipe being connected to the right outlet of the cooling channel.

[0007] The present invention is further configured such that: a limiting rod is fixedly installed on both the left and right sides of the upper end of the movable frame, and the limiting rod and the fixed frame are movably interlocked.

[0008] The present invention is further configured such that the punch is located above the lower die.

[0009] The present invention is further configured such that the fixing frame is U-shaped.

[0010] In summary, this utility model has the following beneficial effects: Coolant from the storage tank is pumped into the cooling channel inside the punch via a pump and outlet pipe. The coolant flows along the cooling channel, carrying away the heat generated by the punch, and then flows into the collection tank through the drain pipe, forming a closed cooling cycle system. This design effectively reduces the operating temperature of the punch, reduces wear caused by high temperature, and extends its service life. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] A punch press for processing heat sinks of a heat dissipation module, such as Figures 1 to 2As shown, the device includes a worktable 1 and a lower mold 2. The lower mold 2 is fixed to the upper end of the worktable 1. A fixed frame 3 is fixedly installed on the upper end of the worktable 1. A hydraulic cylinder 4 is fixedly installed on the top of the fixed frame 3. A movable frame 5 is fixedly installed on the output end of the hydraulic cylinder 4. An upper mold 6 is fixedly installed on the lower end of the movable frame 5. A punch 7 is fixedly installed on the middle side of the lower end of the upper mold 6. A cooling channel 8 is U-shaped inside the punch 7. A liquid storage tank 9 and a liquid pump 10 are fixedly installed on the upper left side of the upper mold 6. The liquid pump 10 and the liquid storage tank 9 are internally connected. The output end of the liquid pump 10... A liquid outlet pipe 11 is fixedly installed, and the outlet of the liquid outlet pipe 11 is connected to the inlet of the cooling channel 8. A collection tank 12 is placed on the upper right side of the upper mold 6. A drain pipe 13 is fixedly installed on the outer surface of the collection tank 12, and the drain pipe 13 is connected to the right outlet of the cooling channel 8. The drain pipe 13 is movably inserted through the right outlet of the cooling channel 8, and the collection tank 12 is movably placed on the upper mold 6. This design facilitates the user to quickly disassemble the collection tank 12 for liquid discharge, simplifying the maintenance process. The punch 7 is made of high-strength, wear-resistant materials, such as cemented carbide or ceramic materials. These materials not only have excellent hardness and wear resistance, but can also withstand high operating temperatures, ensuring that the punch 7 maintains high performance during long-term use.

[0018] like Figure 1 As shown, a limiting rod 14 is fixedly installed on both the left and right sides of the upper end of the movable frame 5. The limiting rod 14 and the fixed frame 3 are movably interlocked. The design of the limiting rod 14 is mainly to ensure that the movable frame 5 maintains stable and precise guidance when moving up and down. Through the movable interlocking connection with the fixed frame 3, the limiting rod 14 can restrict the movable frame 5 to move only in the vertical direction, avoiding any unnecessary lateral deviation or swing, which helps to ensure the accuracy and consistency of the stamping operation.

[0019] like Figure 1 As shown, the punch 7 is located above the lower die 2. The fact that the punch 7 is located directly above the lower die 2 means that when the hydraulic cylinder 4 drives the movable frame 5 to move downward, the punch 7 can directly align with and apply force to the workpiece placed on the lower die 2, thereby completing a precise stamping action.

[0020] The fixing frame 3 is U-shaped. The U-shaped structure can provide better support and stability, especially when subjected to pressure from the hydraulic cylinder 4, and can effectively prevent deformation or twisting.

[0021] Working principle: When the workpiece is placed on the lower die 2 and the punch press for processing the heat dissipation module is started, the hydraulic cylinder 4 drives the movable frame 5 to move downward. The movable frame 5 drives the upper die 6 and the punch 7 to apply pressure to the lower die 2, completing the stamping action. During this process, a large amount of heat is generated due to the high-pressure contact between the punch 7 and the metal sheet.

[0022] To prevent overheating of the punch 7, coolant in the storage tank 9 is pumped into the cooling channel 8 inside the punch 7 via the pump 10 and the outlet pipe 11. The coolant flows along the cooling channel 8, carrying away the heat generated by the punch 7, and then flows into the collection tank 12 through the drain pipe 13, forming a closed cooling circulation system. This design effectively reduces the operating temperature of the punch, minimizing wear caused by high temperatures. The cooling channel 8, directly located inside the punch 7, can quickly transfer the heat generated during operation to the flowing coolant. Thus, even during high-frequency, high-pressure punching operations, the temperature of the punch 7 can be effectively controlled. The U-shaped cooling channel 8 increases the flow path length of the coolant inside the punch 7, thereby extending the contact time between the coolant and the punch 7, improving heat exchange efficiency, ensuring a more uniform temperature distribution, and further enhancing the cooling effect.

[0023] By using the built-in cooling channel 8 and the coolant circulation system, the operating temperature of the punch 7 is significantly reduced, wear caused by overheating is reduced, and the service life of the punch 7 is greatly extended.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
