Description of the invention: • Technical field to which the invention pertains: The present invention relates to a bicycle crank manufacturing method, and in detail, a method for manufacturing different crank sizes and being light in weight. [Prior Art] According to the bicycle, the bicycle has the characteristics of being able to travel far and environmentally friendly. In the future, which is focused on leisure life, it is called to engage in outdoor activities to experience the comfort of nature, the most suitable and the most suitable for sports health. It is a bicycle ride, and the bicycle ride can not only forge the chain late, but also enjoy the nature, is the most suitable for modern sports, and in the case of the implementation of the two days of the week, and the establishment of the bicycle patent road, people have added a lot of rest. With time and movement space, the bicycle market in today's living environment has been paid more and more attention. Modern people's requirements for bicycles are not only sturdy and durable, but also pay attention to the light and comfortable function. When the structure is stable, the structure of each part of the bicycle body is changed to a carbon fiber composite material, which has become a trend. 9 In the case of a carbon fiber composite crank, the two ends of the crank need to be pivotally connected to the pedal and the five-way pipe, and the characteristics of the carbon-dimensional composite material are too hard and brittle to be an effective pivot joint, so Increase the structural strength of the pivot joint, the bridge joint needs to be embedded with metal pipe fittings to reinforce the shortage of carbon fiber composite material. Both the metal pipe fitting and the carbon fiber composite material crank are in the manufacturing process, and the conventional method is to use a small area. Carbon fiber patches are pieced together one by one to form the shape of the crank of the required size. After the crank is formed, the metal parts are inserted, and finally the adhesive is applied to complete the assembly; however, this method causes a lot of troubles in the manufacturing steps. , and the structure; the lack of structure; 5 1363725 The use of a small area of carbon fiber patch one by one to synthesize the production of the crank, the flat patch to form a three-dimensional crank has its production difficulty, not only a waste of time It also requires more professional production staff, so the cost is not expensive, and the interior of the crank needs to form part of the support block because of the fit, instead of The whole hollow structure, the cost of the material is more heavy and heavier; and after the completion of the crank, the metal pipe fitting is additionally inserted, the joint strength of the pipe fitting and the crank does not reach the ideal stability point. Stable @sexual wealth is insufficient, so it is necessary to re-adhesive glue to reinforce, and it is more inconvenient to make the glue or finishing and preparation, so on the whole, it can be said that it does not have read. It is necessary to improve it. In view of the above-mentioned unsatisfactory features of the crank structure of the above-mentioned conventional use, the present inventors deeply felt that there is a change of improvement, and the research and improvement of the product of the product is studied, and the design and modification are designed for a long time. The invention is more practical and promotes the progress of the industry. [Summary of the Invention]
