[0002] Heat pipes are highly efficient heat transfer elements widely used in electronic equipment cooling, air conditioning systems, industrial heat exchangers, and other fields. Heat pipes utilize an internal working fluid that absorbs heat and turns into vapor in the evaporation section, and releases heat and turns back into liquid in the condensation section, thus achieving efficient heat transfer from high-temperature to low-temperature regions. Pneumatic pipe bending machines are specialized mechanical devices used to bend straight pipes into specific angles or shapes, and are particularly suitable for processing high-precision and high-quality pipe fittings such as heat pipes.

[0003] Based on the above, the inventors have discovered the following problems: There are many types of heat pipes available now.

[0033] Please see Figures 1-5This utility model provides a technical solution: a pneumatic tube bending machine for heat pipe production, including a tube bending assembly 1. The tube bending assembly 1 includes a base 101, a tube bending frame 103, and two sliding blocks 104. An installation rod 105 is fixedly installed at the top of one end of each of the tube bending frame 103 and the two sliding blocks 104. A fixing head 106 is fixedly installed at the top of the installation rod 105. A fixing groove 107 is formed on the outer side of the fixing head 106. A replacement component 2 is sleeved on the outer side of the installation rod 105.

The quick-release fixing piece 3 includes... A fixing sleeve 301 is fitted onto the outside of the fixing head 106. A pressure plate 302 is fixedly installed at the bottom of the fixing sleeve 301. The pressure plate 302 facilitates the clamping and fixing of the replacement component 2. Several ball holes 303 are opened on the side of the fixing sleeve 301. Fixed balls 304 are provided inside the ball holes 303. A handle glove 307 is fitted onto the outside of the fixing sleeve 301. The handle glove 307 pushes the fixed balls 304 away from the handle glove 307, so that the fixed balls 304 are engaged in the fixing groove 107.

[0036] The replacement component 2 includes a pipe bending die 201, a bending die 202, and a clamping die 203. Each of the pipe bending die 201, the bending die 202, and the clamping die 203 has a mounting hole 205 in the middle. The mounting hole 205 is sleeved on the outside of the mounting rod 105.

[0038] The clamping mold 203 has a clamping groove 206 and a fixed frame 207 is fixedly installed on one side. The fixed frame 207 has a clamping block 209 inside. The clamping block 209 is designed to work with the clamping mold 203 to clamp and fix the heat pipe, thus preventing slippage during the bending process.

[0039] The clamping block 209 has guide grooves 210 at both the top and bottom. The guide grooves 210 are slidably connected to the fixed frame 207. A second threaded rod 211 is fixedly installed on one side of the clamping block 209 and is slidably connected to the fixed frame 207 through the guide grooves 210, which facilitates the guidance and limitation of the sliding of the clamping block 209.

[0040] The fixed frame 207 has a rotating seat 208 on one side, and the rotating seat 208 is rotatably connected to a clamping knob 212. The clamping knob 212 is threadedly connected to the second threaded rod 211. The connection between the clamping knob 212 and the second threaded rod 211 makes it easy to adjust the position of the clamping block 209 by rotating the clamping knob 212.

[0041] The base 101 has a pneumatic telescopic rod 102 fixedly installed at one end, and two limiting sleeves 108 fixedly installed at the other end. The output end of the pneumatic telescopic rod 102 is fixedly connected to the bending frame 103. The fixed connection between the output end of the pneumatic telescopic rod 102 and the bending frame 103 facilitates the operation of the pneumatic telescopic rod 102 to control the bending frame 103 to drive the bending mold 201 to bend the heat pipe.

[0042] The limiting sleeve 108 is slidably connected to the sliding block 104. A threaded sleeve 109 is fixedly installed on the top of the limiting sleeve 108. The threaded sleeve 109 is threadedly connected to a first threaded rod 110. A hexagonal block 111 is fixedly installed on the top of the first threaded rod 110. A locking block 112 is fixedly installed on the bottom of the first threaded rod 110. By fixing the locking block 112 on the bottom of the first threaded rod 110, the position of the sliding block 104 can be adjusted according to actual needs. Rotating the hexagonal block 111 causes the locking block 112 to press and fix the sliding block 104.

[0043] Specifically, the working principle of this pneumatic tube bending machine for heat pipe production is as follows: During use, a locking block 112 is fixedly installed at the bottom of the first threaded rod 110, allowing for adjustment of the sliding block 104 position as needed. Rotating the hexagonal block 111 causes the locking block 112 to press and fix the sliding block 104. A replacement component 2 is sleeved on the outside of the mounting rod 105, allowing for selection of a suitable replacement component 2 as needed. This facilitates bending the heat pipe in conjunction with the tube bending assembly 1. The mounting hole 205... The bending die 201 and the mounting rod 105 at the top of the bending frame 103 are rotatably connected. The bending die 202 and the clamping die 203 are rotatably connected to the mounting rod 105 at the top of the sliding block 104. The tube groove 204 and the clamping groove 206 facilitate the positioning of the heat-conducting pipe. The clamping block 209, in conjunction with the clamping die 203, facilitates the clamping and fixing of the heat-conducting pipe, preventing slippage during the bending process. The pressure plate 302 facilitates the replacement component 2. The clamping and fixing are achieved by a handle glove 307 fitted on the outside of the fixing sleeve 301. This handle glove 307 pushes the fixing ball 304 away from the handle glove 307, causing the fixing ball 304 to engage in the fixing groove 107. This secures the quick-release fixing member 3 to the fixing head 106, allowing the quick-release fixing member 3 to fix the replacement component 2. Furthermore, the quick-release fixing member 3 can be easily disassembled when the handle glove 307 moves upward away from the ball hole 303, facilitating the replacement of the replacement component 2. This is achieved via the guide rod 3. A limiting block 306 is fixedly installed at the top of 05 to limit the sliding of the handle glove 307. The top of the push spring 309 is fixedly connected to the bottom of the limiting block 306, so that the push spring 309 can provide elastic force to push the handle glove 307 downward. Thus, the handle glove 307 can be kept outside the ball hole 303 during use. The output end of the pneumatic telescopic rod 102 is fixedly connected to the bending frame 103, so that the pneumatic telescopic rod 102 can control the bending frame 103 to drive the bending mold 201 to bend the heat conduction pipe.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
