Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: Reference Figure 1-5The illustrated thermal fixture for a support tube includes a support frame 1. The support frame 1 provides a stable support base for the entire fixture, ensuring its stability during use and preventing vibration from affecting processing accuracy. A rotating disk 24 is rotatably connected to the side of the support frame 1. The rotating disk 24 can rotate around its connection point with the support frame 1, facilitating the adjustment of the position of the fixed disk 12. This improves the ease of operation for the installation, processing, and subsequent treatment of the support tube. A fixed disk 12 is provided on the side of the rotating disk 24, which is used to support the heated soft tube. The heating and softening components are provided with mounting surfaces to ensure that the relative positions of each component are fixed during operation, thus ensuring stable processing. A heating and softening component is provided on the side of the fixed disk 12; a forming component is also provided on the side of the fixed disk 12. The heating and softening component includes a pair of heating tubes 14 slidably connected to the side of the fixed disk 12. The heating tubes 14 can slide on the side of the fixed disk 12 to facilitate the heating and covering of the support tube. The heating tubes 14 are arranged in a semi-circular plate shape, and the pair of heating tubes 14 are symmetrically arranged. This structural design allows for heating of the support tube from both sides. Uniform heating ensures more even heating of the support tube, avoiding localized overheating or underheating. Multiple grooves 28 are formed on the inner wall of the heating tube 14. These grooves provide installation space for the resistance heating wire 18 and also concentrate heat to enhance the heating effect. The resistance heating wire 18 is installed on the inner wall of the groove 28, generating heat through current to provide a heat source for the softening and heating of the support tube. A copper plate 19, which is connected to the resistance heating wire 18, is fixedly connected to the inner wall of the groove 28. The copper plate 19 has good thermal conductivity, enabling rapid heating of the resistance wire. The heat generated by the wire 18 is transferred to the inner wall of the heating tube 14, and then to the support tube, improving heating efficiency and the uniformity of heat transfer. The forming assembly includes a pair of molds 13 slidably connected to the side of the fixed disc 12. The molds 13 can slide on the side of the fixed disc 12, facilitating the adjustment of the mold spacing and position according to different specifications of support tubes, realizing the forming process of support tubes of different sizes, and improving the versatility of the molds. The pair of molds 13 are symmetrically arranged, which can apply uniform pressure to the support tube during the forming process, ensuring the shape and dimensional accuracy of the support tube after forming. The side of the fixed disc 12 is fixedly connected to a positioning block 20 for positioning the support tube. The positioning block 20 can accurately limit the position of the support tube, preventing the support tube from shifting during heating and forming, and ensuring processing quality. Both ends of the positioning block 20 are provided with anti-slip textures, which increase the friction between the anti-slip textures and the support tube, further improving the stability of the support tube positioning and preventing it from sliding during processing.

[0026] Example 2: Reference Figure 1-5Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a positioning frame 11 is fixedly connected to the outer side of the support frame 1. The positioning frame 11 plays a role in positioning and supporting, ensuring that the fixed disk 12 maintains an accurate position during operation and does not shift. The fixed connection between the positioning frame 11 and the fixed disk 12 further enhances the stability of the fixed disk 12. The rotating disk 24 is rotatably connected to the fixed disk 12, allowing the rotating disk 24 to rotate flexibly relative to the fixed disk 12, providing a basis for the equipment to achieve different working states. A pair of symmetrically arranged guide grooves 25 are provided on the inner side of the rotating disk 24. The guide grooves 25 provide guidance for the guide rod 29, allowing the guide rod 29 to slide along a specific direction during movement, ensuring the accuracy of the movement. The guide rod 29 is slidably connected to the inner wall of the guide groove 25. The guide rod 29 slides within the guide groove 25, realizing the guidance and constraint of the relative movement between the rotating disk 24 and the fixed disk 12. The inner side of the fixed disc 12 is provided with a pair of sliding grooves 30 that are adapted to the guide rod 29. The sliding grooves 30 cooperate with the guide rod 29 to further restrict the movement trajectory of the guide rod 29 and ensure the stability and reliability of the rotating disc 24 when it rotates. A guide block 27 is fixedly connected to the outer side of the guide rod 29. The guide block 27 cooperates with the slide groove 26 to prevent the guide rod 29 from disengaging during sliding and to enhance the stability of the guide rod 29 during sliding. The inner wall of the slide groove 30 is provided with a slide groove 26 that matches the guide block 27. The slide groove 26 provides sliding space for the guide block 27, ensuring the smooth connection and movement between the guide rod 29 and the fixed disc 12. A fixed plate 2 is fixedly connected to the outer side of the support frame 1. The fixed plate 2 provides the mounting base for components such as the mold 13 and also plays a certain supporting and fixing role, ensuring the stability of related components during operation. A feed port 7 is provided on the inner side of the fixed plate 2. The feed port 7 is used for material input, which facilitates the material to enter the equipment for processing. A motor 3 is fixedly connected to the side of the fixed plate 2. The motor 3 provides rotational power for the bidirectional threaded rod 4 and is the power source for moving the mold 13.A bidirectional threaded rod 4 is fixedly connected to the output end of motor 3. The bidirectional threaded rod 4, through its own rotation, converts the rotational motion of motor 3 into the linear motion of slider 5, thereby adjusting the position of mold 13. Slider 5s are threadedly connected to the outer ends of both ends of the bidirectional threaded rod 4. The slider 5s cooperate with the bidirectional threaded rod 4, achieving linear movement under the drive of the bidirectional threaded rod 4, thus moving mold 13. A pair of sliders 5 are fixedly connected to a pair of molds 13, allowing mold 13 to move with the movement of sliders 5, meeting different working requirements, such as adjusting the spacing between molds 13 to accommodate materials of different sizes. The side of the fixing plate 2 is fixedly connected to... A positioning plate 6 supports and positions the bidirectional threaded rod 4, ensuring its stability during rotation and preventing wobbling or displacement. The bidirectional threaded rod 4 is rotatably connected to the side of the positioning plate 6, ensuring its flexible rotation and effective power transmission. A slot 15 is provided on the inner side of the support frame 1, providing installation space for components such as the vent pipe 16, making efficient use of the internal space and resulting in a more compact structure. An air pump 21 is fixedly connected to the bottom of the support frame 1. The air pump 21 serves as the air source, providing high-pressure gas to the entire jet system and is the core component for enabling the high-pressure nozzle 17 to jet. A guide pipe 22 is fixedly connected to the output end of the air pump 21, transmitting the high-pressure gas from the air pump 21 to the vent pipe 16. One end of the guide pipe 22 is fixedly connected to the vent pipe 16, which distributes the high-pressure gas from the guide pipe 22, ensuring even distribution to each high-pressure nozzle 17. Multiple interconnected high-pressure nozzles 17 are fixedly connected to the outside of the vent pipe 16. The high-pressure nozzles 17 spray out high-pressure gas to cool and shape the formed support tube.

[0027] The working principle of this utility model is as follows: The support tube is inserted into the outside of the positioning block 20 through the feed port 7. The motor 9 drives the gear 23 and the rotating disk 24 to rotate through the gear 10. Through the cooperation of the guide groove 25 and the sliding groove 30, a pair of guide rods 29 drive the corresponding pair of heating tubes 14 to move closer to each other, so that multiple copper plates 19 are in contact with the support tube. The resistance heating wire 18 is energized, and the support tube is heated and softened by the multiple copper plates 19. The motor 9 is reversed to move the pair of heating tubes 14 away from each other to avoid obstructing the mold 13. The motor 3 drives the bidirectional threaded rod 4 to rotate, and the slider 5 drives the pair of molds 13 to move closer to each other to shape the support tube. The air pump 21 is controlled to introduce high-pressure gas into the air pipe 16 through the air guide pipe 22, and spray it out through multiple high-pressure nozzles 17 to cool the support tube.
