Description

Technical Field

[0001] This utility model relates to the field of carbon fiber tube processing technology, specifically to an adjustable auxiliary device for carbon fiber tube curing and molding. Background Technology

[0002] In the production of carbon fiber products, the curing and molding of carbon fiber tubes is one of the key processes. Typically, this process involves placing the resin-wound carbon fiber preform onto a specific support structure and curing it under constant temperature or heating conditions to ensure shape stability and meet material performance standards. To improve production efficiency, batch curing is now commonly used, where multiple carbon fiber tubes are simultaneously placed on a support structure for synchronous curing.

[0003] Existing carbon fiber tube curing auxiliary support devices mostly adopt a fixed bracket structure, in which the carbon fiber tube is placed directly on the horizontal support frame for curing. Due to the fixed structure, the carbon fiber tube cannot be heated evenly during the curing process, which can easily cause product deformation or uneven strength. At the same time, such devices can usually only be adapted to carbon fiber tubes of a single length. When it is necessary to process products of different lengths, different support structures need to be changed, which is cumbersome, has poor adaptability, and affects production efficiency and equipment flexibility.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: this easily adjustable carbon fiber tube curing and molding auxiliary device enables rapid adaptation and uniform heat curing of carbon fiber tubes of different lengths and specifications, improving equipment versatility and product quality.

[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. 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: an adjustable carbon fiber tube curing and molding auxiliary device, including a support frame 1. The support frame 1 has an overall U-shaped frame structure. Adjustable support shaft assemblies, consisting of fixed sleeves 2 and extension shafts 3, are provided on the inner sides of both sides of the support frame 1. The outer end of the adjustable support shaft assembly is connected to a disc base 4. The fixed sleeves 2 are horizontally fixed to the inner side wall of the support frame 1, and the inner end of the extension shaft 3 extends movably into the fixed sleeves 2. A pin is inserted at the connection point of the fixed sleeves 2 and the extension shaft 3. A rotating guide ring 5 is provided on the outer side of the disc base 4. The rotating guide ring 5 is connected to a built-in ring... The annular guide rail 6 is connected to the inner wall of the disc base 4. The annular guide rail 6 is made of existing high-temperature resistant alloy steel material, and its surface is hardened, giving it good wear resistance and thermal stability. Multiple locking rings 7 are sequentially welded and fixed along the circumferential direction on the outer circumferential surface of the rotating guide ring 5. These locking rings 7 are used to engage and fix the ends of the carbon fiber tube. This structure allows for the alignment of the two ends of the carbon fiber tube with the corresponding locking rings 7 on both sides. Then, the adjustable support shaft assembly, consisting of the fixed sleeve 2 and the extension shaft 3, is adjusted according to the length of the carbon fiber tube. By changing the depth of the extension shaft 3 inserted into the fixed sleeve 2, different specifications of carbon fiber tubes can be accommodated. Pins are used to secure the tubes. Position and lock the carbon fiber tube according to the hole positions until both ends are fully embedded in the locking ring 7 and firmly clamped. At the same time, the disc base 4 moves synchronously with the support shaft assembly and remains horizontal and stable. The rotating guide ring 5 on its outer side forms a rotatable connection with the disc base 4 through the built-in annular guide rail 6, allowing the carbon fiber tube to rotate smoothly around the axis during the curing process, thereby achieving uniform heating and stress distribution. The overall structure is reasonably designed and the linkage between the components is strong. It not only improves the versatility and ease of operation of the equipment, but also effectively solves the problems of poor adaptability, cumbersome replacement, and product variation caused by uneven heating due to the non-adjustable structure of traditional fixed brackets. To address the issue of inconsistent shape and strength, a positioning ring 401 is fixedly fitted at the center of the disc base 4, and the positioning ring 401 is sleeved on the outer end of the extension shaft 3. A locking bolt is threaded onto the positioning ring 401. This structure allows the disc base 4 to slide axially along the extension shaft 3 via the positioning ring 401 for position adjustment. After position adjustment, the locking bolt is tightened on the positioning ring 401 to press against the outer wall of the extension shaft 3, thus achieving a stable fixation of the disc base 4 on the extension shaft 3. This further ensures the flexibility and adaptability of the disc base 4 in adjusting its position. Elastic clamping elements 701 are symmetrically fixed inside the locking ring 7.Furthermore, the inner wall of the elastic clamping member 701 is an arc-shaped surface structure. This elastic clamping member 701 is made of spring steel sheet material with high elasticity and structural strength. Its inner wall is an arc-shaped surface structure that matches the end of the carbon fiber tube. During the clamping process, it achieves flexible clamping of the end of the carbon fiber tube through elastic deformation, which not only ensures clamping stability but also avoids damage to the tube surface. This not only improves the safety and reliability of the clamping process but also enhances the device's adaptability to carbon fiber tubes of different specifications. The bottom plate of the support frame 1 is provided with a heat-conducting bulge 8, and multiple vertical heat-conducting ribs 801 are arranged at intervals on the top of the heat-conducting bulge 8. This structure of the heat-conducting bulge 8 is an arc-shaped bulge structure, used to increase the heat conduction area in the contact area with the bottom of the carbon fiber tube. The heat-conducting ribs 801 are all made of metal material with good thermal conductivity. Materials such as aluminum alloy or copper alloy can be coated with anti-oxidation or anti-stick coatings to improve heat conduction efficiency and prevent direct adhesion to the carbon fiber tube. This allows for uniform heat conduction from the bottom during the carbon fiber tube curing process, effectively improving problems such as product deformation and inconsistent curing caused by uneven heating in traditional support methods. This further enhances the overall heating uniformity and molding quality of the device. The disc base 4 is located at the same horizontal position inside the support frame 1, and the bottom height of the disc base 4 is higher than the top height of the heat-conducting protrusion 8. This structure of the disc base 4 ensures that the carbon fiber tube is horizontal after installation, and that the carbon fiber tube does not interfere with the heat-conducting protrusion 8 after being installed on the rotating guide ring 5. This ensures that the rotating guide ring 5 can drive the carbon fiber tube to rotate smoothly around the axis, providing sufficient space for the rotation of the carbon fiber tube.

[0018] Working principle: When using this easily adjustable carbon fiber tube curing and molding auxiliary device, firstly, according to the length of the carbon fiber tube to be cured, adjust the adjustable support shaft assembly consisting of the fixed sleeve 2 and the extension shaft 3 on both sides of the support frame 1. The required length is adapted by changing the depth of the extension shaft 3 inserted into the fixed sleeve 2, and the pin is inserted into the appropriate hole for positioning and locking. Then, the disc base 4 is fitted onto the outer end of the extension shaft 3 through the positioning ring 401, and after sliding along the extension shaft 3 to the appropriate position, the locking bolt is tightened to complete the fixation until both ends of the carbon fiber tube are aligned with the locking rings 7 on both sides and pushed into them. The elastic clamping member 701 undergoes elastic deformation during the clamping process to achieve clamping. When multiple carbon fiber tubes are installed on the support frame 1 and placed in the curing equipment, the rotating guide ring 5 drives the carbon fiber tube to rotate slowly with the internal transmission structure of the equipment to complete the entire curing process, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
