Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing fixture technology, and in particular to a fixing fixture for heat pipe sintering. Background Technology
[0002] In the heat pipe manufacturing process, sintering is a crucial step that determines the heat pipe's thermal conductivity and structural stability. It requires specialized fixtures to position the heat pipe and, in conjunction with a heating device, to achieve precise sintering. Currently, most commonly used heat pipe sintering fixtures in the industry are simple frame structures, only meeting basic load-bearing and positioning requirements. With increasing heat pipe production efficiency and higher quality standards, existing fixtures are gradually revealing numerous technical shortcomings and are ill-suited for modern production environments.
[0003] Existing fixtures have significant shortcomings in structural stability and service life. During sintering, the fixture needs to frequently connect and disconnect the upper and lower components to complete the placement and sealing of the heat pipe. However, when the upper and lower components are in direct contact and collision, there is a lack of effective protective structure, which can easily lead to wear, deformation, or even cracking of the components after long-term use. This not only increases the frequency of fixture replacement and raises production costs, but also causes the connection gap to widen due to component deformation, making it easy for heat to leak during sintering and making it impossible to maintain a stable sintering temperature environment. This, in turn, affects the sintering quality of the heat pipe and reduces the product qualification rate. To solve the above problems, this application proposes a fixing fixture for heat pipe sintering. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixture for heat pipe sintering. The new fixture effectively buffers the impact force generated by frequent contact and collision of components by adding a reinforcing structure to the outside of the core docking component, reducing the probability of component wear, deformation or cracking, and significantly reducing the replacement frequency of the fixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixture for heat pipe sintering includes a base with a sintering port through its center. Four columns are fixedly connected to the top of the base, and a heat-conducting iron plate is fixedly connected to all four columns. A first inner liner is fixedly connected to the top of the heat-conducting iron plate, and a first fixing ring is fixedly connected to the outer wall of the first inner liner. A liftable second inner liner is located above the first inner liner, and a second fixing ring is fixedly connected to the outer wall of the second inner liner. A lifting plate is fixedly connected to the top of the second inner liner. A C-shaped reinforcing plate is fixedly connected to the side wall of the base, and a hydraulic rod is fixedly connected to the C-shaped reinforcing plate. The output end of the hydraulic rod is fixedly connected to the lifting plate.
[0006] Preferably, the base has four support legs fixedly connected to its bottom, and each of the four support legs is equipped with a locking caster wheel, which are arranged in a rectangular pattern.
[0007] Preferably, a ventilation cavity is formed between the base and the heat-conducting iron plate, and the sintering port is connected to the ventilation cavity.
[0008] Preferably, a sintering cavity is formed in the center of the first inner liner.
[0009] Preferably, the bottom of the first fixing ring is fixedly connected to the top of the heat-conducting iron plate, and the top of the second fixing ring is fixedly connected to the bottom of the lifting plate.
[0010] Preferably, the first fixing ring and the second fixing ring are provided with a plurality of through grooves, and the plurality of through grooves are distributed at equal intervals.
[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The new fixture effectively buffers the impact force generated by frequent contact and collision of components by adding a reinforcing structure to the core docking components, reducing the probability of component wear, deformation or cracking, and significantly reducing the replacement frequency of the fixture.
[0012] 2. The evenly distributed channels in the reinforced structure of the fixture, together with the ventilation space reserved between the base and the heat-conducting components, form an efficient air circulation path.
[0013] In summary, the new fixture effectively buffers the impact force generated by frequent contact and collision of components by adding a reinforcing structure to the core docking components, reducing the probability of component wear, deformation or cracking, and significantly reducing the replacement frequency of the fixture.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figures 1-3 A fixture for heat pipe sintering includes a base 1, which serves as the basic load-bearing structure for the entire device, providing stable support for the components above. A sintering port 2 is provided through the center of the base 1, providing a channel for the flame of the external combustion device to ensure that heat can be transferred to the sintering area. Four support legs are fixedly connected to the bottom of the base 1, raising the base 1 to reserve installation space. Locking casters 3 are installed at the bottom of the four support legs, enabling flexible movement and fixation of the device and improving ease of use. The four locking casters 3 are arranged in a rectangular pattern.
[0018] Four columns 4 are fixedly connected to the top of the base 1. The columns 4 support the heat-conducting iron plate 5 and maintain the distance between it and the base 1. The heat-conducting iron plate 5 is fixedly connected to the four columns 4 together. The heat-conducting iron plate 5 can evenly conduct heat to the sintering component above. A ventilation cavity 6 is opened between the base 1 and the heat-conducting iron plate 5. The ventilation cavity 6 ensures air circulation, which helps with complete combustion and heat circulation. The sintering port 2 is connected to the ventilation cavity 6, allowing the flame to enter the ventilation cavity 6 through the sintering port 2 and act on the heat-conducting iron plate 5. The top of the heat-conducting iron plate 5... A first inner liner 7 is fixedly connected, providing bottom support and positioning for the heat pipe. A sintering cavity 8 is opened in the center of the first inner liner 7, providing space for the heat pipe and serving as the main working area for heat pipe sintering. A first fixing ring 9 is fixedly connected to the outer wall of the first inner liner 7, enhancing the structural strength of the first inner liner 7 and reducing its loss in collisions. The bottom of the first fixing ring 9 is fixedly connected to the top of the heat-conducting iron plate 5, further stabilizing the position of the first inner liner 7 through the connection with the heat-conducting iron plate 5.
[0019] Above the first inner liner 7 is a liftable second inner liner 10. The second inner liner 10, through its lifting mechanism, cooperates with the first inner liner 7 to open and close the sintering chamber 8. A second fixing ring 11 is fixedly connected to the outer wall of the second inner liner 10, providing protection and reinforcement. The top of the second fixing ring 11 is fixedly connected to the bottom of the lifting plate 12, enabling synchronous lifting and lowering of the second inner liner 10. The top of the second inner liner 10 is fixedly connected to the lifting plate 12, which acts as a load-bearing structure to drive the second inner liner 10 and the second fixing ring 12. The ring 11 moves as a whole. A C-shaped reinforcing plate 13 is fixedly connected to the side wall of the base 1. The C-shaped reinforcing plate 13 provides a stable installation support for the hydraulic rod 14. The hydraulic rod 14 is fixedly connected to the C-shaped reinforcing plate 13. The hydraulic rod 14 provides power output for the lifting of the lifting plate 12. The output end of the hydraulic rod 14 is fixedly connected to the lifting plate 12. The precise drive of the lifting plate 12 is achieved through direct connection. Multiple through slots 15 are opened on the first fixed ring 9 and the second fixed ring 11. The through slots 15 are used for ventilation and heat dissipation to avoid excessive local temperature. The multiple through slots 15 are distributed at equal intervals.
[0020] In this invention, the operator places the heat pipe to be sintered into the sintering chamber 8, and activates the hydraulic rod 14 to move the lifting plate 12, the second inner liner 10, and the second fixing ring 11 downwards until the bottom of the second inner liner 10 abuts against the top of the first inner liner 7, thus sealing the sintering chamber 8. An external combustion device burns flames to the bottom of the heat-conducting iron plate 5 through the sintering port 2, which can perform sintering operations on the heat pipes in the sintering chamber 8. During the frequent contact and collision between the first inner liner 7 and the second inner liner 10, the first inner liner 7 and the second inner liner 10 are prone to damage. By adding the first fixing ring 9 and the second fixing ring 11 to the outer wall of the first inner liner 7 and the second inner liner 10, the internal first inner liner 7 and the second inner liner 10 can be protected, extending the service life of this device.
