[0042] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0043] The words expressing positions and directions described in this utility model are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of this utility model.

[0044] Referring to Figures 1 to 7 , this application provides a heat pipe processing die, including: a circular heat pipe 1, a first die body 2, a moving press tool, and a second die body 3.

[0045] Specifically, the first die body 2 is used for placing the circular heat pipe 1. The first die body 2 is preferably a fixed die, that is, when the first die body 2 and the second die body 3 are closed, the first die body 2 is preferably in a static state. Of course, in other embodiments, the first die body 2 can also be in a moving state and the second die body 3 can be in a static state, which is not uniquely limited herein.

[0046] The moving press tool is slidably arranged on the first die body 2 and is used for extruding the circular heat pipe 1. As a preferred mode, the moving press tool includes two moving blocks 4. The two moving blocks 4 are slidably arranged on the first die body 2, and the two moving blocks 4 are respectively provided with first inclined chutes 401; the first inclined chutes 401 are preferably inclined surfaces arranged on the opposite sides of the two moving blocks 4. The second die body 3 is provided with two receiving grooves 301, and second inclined chutes 302 are arranged inside the receiving grooves 301; the second inclined chutes 302 are preferably inclined surfaces arranged on the inner sides of the two receiving grooves 301 away from one side. The two moving blocks 4 can enter the receiving grooves 301, and the two inclined surfaces preferably adopt the same inclination angle, so that the two inclined surfaces can be mutually attached and interact when the two die bodies approach each other, causing the two moving blocks 4 to approach each other. Among them, the circular heat pipe 1 is placed between the two moving blocks 4. When the second die body 3 moves relative to the first die body 2, the second inclined chutes 302 interact with the first inclined chutes 401, causing the two moving blocks 4 to enter the inside of the receiving grooves 301 respectively while approaching each other and extruding the opposite two sides of the circular heat pipe 1, deforming the circular heat pipe 1 into a heat pipe with a pair of parallel surfaces.

[0047] It should be noted that the length of the circular heat pipe 1 is not greater than that of the moving block 4, so as to ensure that the entire pipe body of the circular heat pipe 1 along its length direction can be squeezed by the moving block 4, preventing the situation where the length of the moving block 4 is less than that of the circular heat pipe 1 and the circular heat pipe 1 needs to be moved multiple times, ensuring the squeezing effect of the circular heat pipe 1. The length of the accommodating groove 301 is not less than the length of the moving block 4, ensuring that the top of the moving block 4 can smoothly enter the accommodating groove 301.

[0048] The second die body 3 can move relative to the first die body 2 to contract the moving press tool and cooperate with the first die body 2 to squeeze the circular heat pipe 1; among them, the moving press tool contracts to squeeze the circular heat pipe 1. As a preferred method, the first die body 2 is provided with a moving groove 201 for accommodating the moving block 4. The moving block 4 can slide inside the moving groove 201 and squeeze the circular heat pipe 1 within the moving groove 201. An extrusion part 305 is formed between the two accommodating grooves 301 for squeezing the circular heat pipe 1. During the process that the second die body 3 moves relative to the first die body 2 to make the two moving blocks 4 approach each other to squeeze the circular heat pipe 1, the distance between the second die body 3 and the first die body 2 decreases, thereby squeezing the other two opposite sides of the circular heat pipe 1. The extrusion part 305 of the second die body 3 and the cooperation between the first die body 2 and the two moving blocks 4 can squeeze the circular heat pipe 1 into a heat pipe with a square structure.

[0049] It should be noted that the minimum distance between the two moving blocks 4 is equal to the width of the extrusion part 305, that is, the two moving blocks 4 can squeeze the circular heat pipe 1 into a square heat pipe with a pair of sides equal to the width of the extrusion part 305; the extrusion part 305 is set to a structure flush with the lower surface of the second die body 3. When the first die body 2 and the second die body 3 are closed, the surfaces of the two die bodies are mutually attached. The surface of the extrusion part 305 in contact with the circular heat pipe 1 is in the same plane as the closing surface of the first die body 2, that is, the extrusion part 305 can squeeze the circular heat pipe 1 into a square heat pipe with another pair of sides equal to the depth of the moving groove 201.

[0050] Thus, this heat pipe processing die uses the existing circular heat pipe 1, and through the relatively movable first die body 2 and second die body 3 and driving the contraction of the moving press tool, it squeezes the outer shape of the circular heat pipe 1 into a square heat pipe with adjacent sides perpendicular to each other and opposite sides parallel to each other. The production process is simple. Without the need for an enterprise to set up a separate manufacturing production line, it can produce a square heat pipe with a smaller width compared to the circular heat pipe 1, which can reduce the production cost of the enterprise to a certain extent and has stronger practicability.

[0051] In a specific implementation manner, referring to Figure 2 and Figure 3, at least two guiding channels 402 are formed inside the moving block 4, a guiding member 5 is arranged inside the moving slot 201, the guiding member 5 penetrates through the guiding channels 402 respectively, and the moving block 4 slides along the guiding member 5, thereby guiding the running track of the moving block 4 inside the moving slot 201 and preventing the moving block 4 from shifting or the like. As a preferred mode, a limiting member 501 is provided at the top of the guiding member 5 to prevent the moving block 4 from falling off the guiding member 5, improve the stability of the moving block 4 sliding along the guiding member 5, and keep the processing die with high precision. In this embodiment, a fixing hole 202 is formed in the moving slot 201, and the fixing hole 202 is detachably connected to the guiding member 5, so that the guiding member 5 can be removed from the first die body 2, and further, the detachable assembly between the moving block 4 and the first die body 2 can be realized, which is convenient for the replacement and maintenance of structures such as the moving block 4 in the later stage.

[0052] In a practical application, the guiding member 5 is a bolt with a smooth surface arranged on the outer wall near the top, the moving block 4 moves along the smooth surface of the bolt, the limiting member 501 is an adjusting end of the bolt, and the fixing hole 202 is a threaded hole adapted to the above bolt. Wherein, a receiving channel 403 is formed at the top of the moving block 4 for accommodating the limiting member 501; the adjusting end is in a round cake shape, and an adjusting groove 502 is formed on the upper surface of the adjusting end. The adjusting groove 502 is preferably a regular polygon groove, such as an equilateral triangle groove, a square groove, a regular hexagon groove, etc. The bolt can be rotated to be separated from the threaded hole by a wrench adapted to the adjusting groove 502, and then the moving block 4 can be detached from the moving slot 201.

[0053] It should be noted that both the guiding channel 402 and the receiving channel 403 are kidney-shaped holes. The guiding channel 402 is a kidney-shaped hole with the same diameter as the smooth surface of the bolt, and the receiving channel 403 is a kidney-shaped hole with the same diameter as the adjusting end. During the process of the first die body 2 and the second die body 3 being closed to drive the moving block 4 to move, the guiding member 5 and the limiting member 501 move from one end of the kidney-shaped holes of the guiding channel 402 and the receiving channel 403 to the other end respectively.

[0054] In a specific embodiment, referring to Figures 1 to 4 , first transition fillets 404 are arranged at the top of the side walls of the moving block 4 on both sides of the circular heat pipe 1, which can reduce the inner edge of the moving block 4 from scraping the circular heat pipe 1 during the process of placing the circular heat pipe 1 in the moving slot 201; a second transition fillet 405 is arranged at the top of the first inclined slideway 401, and during die closing, the second transition fillet 405 helps the second inclined slideway 302 to smoothly transition to the surface of the first inclined slideway 401.

[0055] In a specific embodiment, referring to Figures 5 to 7, a first mating fillet 303 is provided at the connection between the extrusion part 305 and the two accommodating grooves 301, and a second mating fillet 304 is provided at the top of the second inclined slideway 302. When the first die body 2 is attached to the second die body 3, the top of the moving block 4 is attached to the inside of the accommodating groove 301, the first transition fillet 404 is attached to the first mating fillet 303. At the same time, the first inclined slideway 401 is in close contact with the second inclined slideway 302, and the second transition fillet 405 is attached to the second mating fillet 304.

[0056] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principles and purposes of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
