Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber bicycle manufacturing and processing, and particularly relates to a local heating device for carbon fiber bicycles without baking. Background Art

[0002] Carbon fiber bicycles, with their unique lightweight and high-strength characteristics, have become the leaders in the modern bicycle manufacturing field. However, in the complex process of manufacturing and processing, carbon fiber bicycles face a severe challenge. Due to process requirements, the product needs to undergo multiple heating treatments, and carbon fiber materials are prone to thermal stress damage in high-temperature environments, which undoubtedly poses a serious threat to the overall performance and lifespan of the bicycle.

[0003] Carbon fiber materials have been widely used in the bicycle manufacturing field due to their excellent mechanical properties and corrosion resistance. However, this material appears to be extremely fragile in high-temperature environments. When a carbon fiber bicycle is subjected to overall heating during processing, due to the uneven temperature difference and stress distribution within the carbon fiber material, thermal stress damage is likely to occur. This damage not only reduces the mechanical properties of the carbon fiber material but also shortens the service life of the bicycle.

[0004] To address this problem, we propose a local heating device for carbon fiber bicycles without baking. The core idea of this method is to decompose the carbon fiber bicycle into multiple local areas and perform targeted heating treatments on each area. Specifically, we first divide the carbon fiber bicycle into several key areas, such as the frame, handlebars, wheels, etc., according to its structural and functional characteristics. Then, different heating methods and temperature parameters are adopted for each area to achieve precise control. Content of the Utility Model

[0005] The utility model provides a local heating device for carbon fiber bicycles without baking to make up for the deficiencies in the prior art.

[0006] A local heating device for carbon fiber bicycles without baking includes two symmetric heating devices on the left and right. Its characteristics are as follows:

[0007] The two symmetric heating devices on the left and right are heating devices with an aluminum block structure. Four adjustable bolts are symmetrically arranged on the upper and lower sides of one heating device. The adjustable bolts are respectively connected to adjustable clamping plates arranged inside the heating device. A heating aluminum plate is provided at the middle position of the heating device. A product clamping position is opened at the center line position after the two heating devices are combined. The upper and lower contact surfaces of the product clamping position are the heating aluminum plate and the adjustable clamping plate.

[0008] Furthermore, to better implement the present utility model, the four adjustable bolts include two left adjusting nuts and bolts at the upper and lower positions on the left side and two right adjusting nuts and bolts at the upper and lower positions on the right side. By adjusting the four bolts, the position of the adjustable clamping plate is controlled.

[0009] Furthermore, to better implement the present utility model, a temperature sensor is embedded at the central position of the heating device, a left temperature sensor is embedded at the center of the heating device on the left side, and a right temperature sensor is embedded at the center of the heating device on the right side.

[0010] Furthermore, to better implement the present utility model, left temperature heaters are installed on both the upper and lower sides of the left temperature sensor, and right temperature heaters are installed on both the upper and lower sides of the right temperature sensor.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By improving the heating method and location, the present utility model realizes local heating of the vehicle frame, thereby reducing the negative impacts brought by vehicle frame heating. First, during the wrapping operation, local areas of the vehicle frame are heated to make the carbon fiber material better adhere to the vehicle frame, improving the performance of the composite material. Second, the method of local heating can reduce the influence of thermal stress on the vehicle frame and extend the service life of the vehicle frame. In addition, during the operation on-site, personnel can use the auxiliary device for shaping, reducing labor intensity and improving production efficiency. Description of the Drawings

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0019] Figure 1 - Figure 2 For a specific embodiment of the present invention, this embodiment is a local heating device for a carbon fiber bicycle without baking, which includes two heating devices on the left and right. There are four adjustable bolts symmetrically arranged up and down on a single heating device, and the bolts are respectively connected to adjustable clamping plates 9. The middle heating part of the heating device is a heating aluminum plate 8, and a temperature sensor is embedded in the aluminum block. Heating devices are installed at the upper and lower positions of the sensor. The upper and lower contact surfaces of the clamping position 7 where the product is located are the heating aluminum plate 8 and the adjustable clamping plate 9.

[0020] In the manufacturing process of carbon fiber frames and rear forks, wrapping yarn is a key step. After this step is completed, we need to strictly protect the glued parts. After this process is normally completed with reinforcing materials, forming and fixing are achieved by using opp materials, and then fixed with high-temperature tapes to ensure the stability of the yarn parts.

[0021] After completing the above steps, we need to heat the carbon fiber frame to form the wrapped yarn material, and this process requires the use of the heating device of this patent. First, place the frame at the clamping position 7 where the product of the heating device is located, which is a position specially designed for the frame. Then, according to the size and structure of the frame, adjust the bolts and nuts 1 and 2 so that the central part of the heating device exactly aligns with the yarn part. In this way, it can ensure a uniform heating process and avoid unnecessary damage to the frame.

[0022] After adjusting the bolts and nuts, we check that the temperature sensor and the temperature heater are normal and then can start the operation panel to heat the frame. During the heating process, it is necessary to ensure that the frame is stable, without shaking, and without gaps. When these conditions are met, it can be considered that the heating process is proceeding normally. Through this local heating method, we can effectively heat the carbon fiber workshop and avoid problems such as fatal damage that may be caused by overall baking heating.

[0023] In summary, the proposal of the local heating device for carbon fiber bicycles in this embodiment provides an effective solution to solve the problem of thermal stress damage of carbon fiber materials in the process of mechanical processing under high-temperature environments. We believe that with the continuous improvement and popularization of this technology, carbon fiber bicycles will show a broader development prospect in the future. At the same time, we also look forward to more researchers being able to join this field to jointly promote the innovation and development of carbon fiber bicycle technology.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
