Technical Field

[0001] The invention relates to the technical field related to bicycles, and in particular to a green and environment-friendly production process for bicycle rims. Background Art

[0002] A bicycle is a two-wheeled land vehicle driven by human pedals, commonly known as a free vehicle, bicycle or bike. Since its birth in the 18th century, bicycles have been deeply loved by people. It has become the best choice for people to exercise and travel in an environmentally friendly way. Bicycles are noiseless, pollution-free, light in weight, simple in structure, inexpensive, easy to use and maintain. They can be used as a means of transportation and transporting goods, as well as for physical exercise. Therefore, they are widely used by people. In the process of bicycle production, the rims need to be processed while ensuring their environmental protection. Therefore, a green and environmentally friendly production process for bicycle rims is particularly needed.

[0003] Because the existing bicycle rim production process still has shortcomings in terms of environmental protection. For example, during the production process, the materials used may not be environmentally friendly, or differences in operating procedures may cause pollution, thereby affecting the environment, and practicality still needs to be ensured. Summary of the invention

[0004] The purpose of the present invention is to provide a green and environmentally friendly production process for bicycle rims to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides a green and environmentally friendly production process for bicycle rims, which is carried out according to the following steps: S1. Choose the right manufacturing materials: Bicycle production needs to start with various raw materials, such as carbon fiber and aluminum alloy. These materials will be processed into prepregs or semi-finished products for frames and rims. In the production plant, these raw materials are processed and pretreated through professional equipment.

[0006] S2. After the material selection is completed, the various parts of the bicycle will be processed.

[0007] S3. The quality inspection standards for bicycle rims mainly include appearance quality, dimensional accuracy, and strength. Appearance quality includes whether the rim surface is flat, free of bubbles and cracks. Dimensional accuracy requires that the diameter, thickness, and roundness of the rim meet certain standards. For strength, tensile tests and impact tests are required to ensure the strength and durability of the rim.

[0008] S4. After the bicycle is manufactured, it needs to be inspected to see if the quality of each component meets the requirements, including the quality of the frame, the smoothness of the gear speed, and the sensitivity of the brake system.

[0009] S5. Bicycles that pass the finished product inspection need to be packaged.

[0010] Preferably, the processing flow in S2 includes a frame molding process, a wheel molding process, a transmission system molding process, a brake system molding process, a seat molding process and a pedal molding process.

[0011] Preferably, the S4 assembly process includes welding process, painting process and quality control.

[0012] Preferably, the frame forming process is generally made of aluminum alloy and carbon fiber. The forming process of the aluminum alloy frame generally adopts extrusion forming or welding forming. Extrusion forming is to extrude the aluminum alloy pipe through a mold, then weld it, and finally perform surface treatment. The forming process of the carbon fiber frame is mainly to put the carbon fiber cloth into a mold and form it by hot pressing or vacuum forming.

[0013] Preferably, the wheel forming process generally consists of a hub, a rim and a tire. The forming of the rim mainly includes riveting, welding and casting. For example, riveting is to connect the foot nails on the rim with the hub to fix them together. The forming process of the hub mainly includes cold forging, casting and CNC processing. The forming process of the tire mainly includes pressing and molding a rubber tire through a mold.

[0014] Preferably, the quality of the welding process will directly affect the strength and durability of the rim. Therefore, during the welding process, attention should be paid to the welding temperature, welding time, and welding current to ensure the welding quality.

[0015] Preferably, the coating process can improve the corrosion resistance and aesthetics of the rim.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By using aluminum alloy and carbon fiber and optimizing the molding process, not only the weight of the rim is reduced and riding efficiency is improved, but also the energy consumption and emissions in the production process are reduced, which is in line with the green and environmentally friendly production concept. Secondly, the improvement of the wheel molding process, especially the molding method of the hub and rim, enhances the strength and durability of the rim and improves the overall performance and safety of the bicycle. Then, the welding process is controlled to ensure the welding quality, further guaranteeing the stability and service life of the rim.

[0031] Working principle: First of all, bicycle production needs to start with various raw materials, such as carbon fiber and aluminum alloy. These materials will be processed into prepregs or semi-finished products of frames and rims. In the production plant, these raw materials are processed and pre-treated by professional equipment. Then, the frame will be further processed and formed by mold forming, cutting, welding or bonding.

[0032] During processing, the required materials of the bicycle are processed, such as the rims. The rims are generally composed of hubs, rims and tires. The molding of the rims mainly includes riveting, welding and casting. Riveting is to connect the foot nails on the rim with the hub to fix them together. When welding, the two ends of the rim are connected by welding. Casting is to pour liquid metal into the rim mold, and the rim is obtained after cooling and solidification. The molding process of the hub mainly includes cold forging, casting and CNC processing. The molding process of the tire mainly involves pressing the rubber tire into a mold, and then processing and assembling the remaining parts.

[0033] Then the bicycle rims are inspected after processing. The inspection standards mainly include appearance quality, dimensional accuracy and strength. Appearance quality includes whether the rim surface is flat, free of bubbles and cracks. Dimensional accuracy requires that the diameter, thickness and roundness of the rim meet certain standards. Strength requires tensile tests and impact tests to ensure the strength and durability of the rims. At the same time, the following technical points need to be noted: 1. Welding process: The quality of welding process will directly affect the strength and durability of the rim. Therefore, during the welding process, attention should be paid to welding temperature, welding time and welding current to ensure welding quality.

[0034] 2. Painting process: The painting process can improve the corrosion resistance and aesthetics of the rims. During the painting process, attention should be paid to the uniformity and thickness of the painting.

[0035] 3. Quality control: The quality of the rims needs to be strictly controlled during the production process, including appearance quality, dimensional accuracy, and strength, to ensure that the produced rims meet quality standards.
