Without losing the appearance and structural stability, the structure of each part of the bicycle body is changed to carbon fiber composite. Material f production has become a trend. In the case of a crank made of carbon fiber composite material, the two ends of the crank need to be pivotally connected with the pedal and the five-way pipe, and the seedlings of the miscellaneous_combination cannot be used as a pivotal joint, so the addition is _ Convergence, miscellaneous f embedding metal (4) material to reinforce the lack of carbon fiber composite material 'metal pipe fittings and carbon fiber composite material f shouting both in the manufacturing process's way of using small pieces of carbon fiber one by one - fit together The size of the required size and size of the crank, in Qucheng bribe red metal parts, the most secret paint on the plastic assembly 20%; however, this kind of plum will cause a lot of manufacturing turn-around, and the lack of finished structure; 200846243 Due to the use of small-area carbon fiber patches to form the cranks one by one, the flat patches have to be formed into a three-dimensional crank, which is difficult to manufacture, not only wastes time but also requires more professional production personnel, so the cost The cost is not enough, and the interior of the crank needs to form part of the support block instead of a complete hollow structure. The cost of the material is heavier and heavier; When the metal material pipe fitting is used, the bonding strength between the pipe fitting and the crank does not reach the optimal stability point, so the stability is insufficient on the tip, so it is necessary to apply the adhesive to reinforce, which is more likely to be used due to the use of the glue. It is inconvenient to produce a card glue, and it is inconvenient to prepare, so it is quite unpractical, and it is still necessary to be improved. The present inventors have supervised the existence of the above-mentioned crank-forming structure. Desiring to the ideal, I deeply feel the need for improvement. I have researched and improved the experience in designing and manufacturing such products. After a long period of time, I have designed the experiment, and the invention has become more secret. The invention aims to provide a method for manufacturing a bicycle crank, which can improve the conventional bicycle crank miscellaneous, and the flat money is combined with the three-dimensional music to reduce the difficulty of the weight. Heavier, more expensive, and more difficult to record, such as the lack of strength of the combination of the traitor and the crank. To achieve the purpose of the invention described in the A, the present invention includes the following steps: & X carbon fiber The frame is used as a clutch for the shape of the crank, and at the end of the carbon fiber skeleton = the younger brother - the three sets of people - the first pipe; the blown skeleton is formed, and the hot air is blown into the skeleton, so that the pipe is fixed and tender; ·财细_The length of the shaft is cut 6 200846243 The moon frame 'touch the skeleton and the other end to form the H set; carbon fiber cloth ship: the second embedded part is inserted into the second pipe and wrapped with carbon fiber cloth And the second pipe; preliminary hot press forming: heating the skeleton to make the carbon fiber cloth and the skeleton high-temperature setting; carbon fiber patch: on the skeleton _ upper carbon fiber patch' so that the carbon fiber patch completely covers the skeleton; hot press forming: heating the skeleton to make the carbon fiber patch The high-temperature stereotype of the skeleton is completed by the bicycle of the present invention. The finished product of the bicycle is made of a carbon-based skeleton as a crank-riding/'soth-complete hollow structure, and the inside of the crank is lighter without a support block; Firstly, the first pipe member and the second pipe member are wrapped in the crank by using the skeleton as a prototype, and the bonding strength between the crank and the official member can be enhanced, and at the end of the carbon fiber shirt, the existing skeleton and the carbon fiber cloth are used. Three-dimensional Form, easier to patch to complete the crank, not only more efficient and can save professional labor, so the invention is a practical and progressive invention, worthy of promotion by the industry, and publicized to the public. [Embodiment] The present invention relates to a bicycle crank manufacturing method. Please refer to the first figure. The Φ bicycle crank manufacturing method mainly includes the following steps: δ and pipe fittings. Please refer to the first figure and the second figure. As shown, a carbon fiber skeleton (10) of a hollow structure is first used as a prototype of a crank, and a skeleton (i0) is formed at one end with a first embedded portion (11) and at the end of the carbon fiber skeleton (10). The first embedded portion (ii) is sleeved into a first tubular member (12) of a metal material; the blown skeleton is formed by blowing hot air from a blow inlet (13) at the bottom end of the skeleton (1〇) to make the first tubular member (12) Forming and combining with the embedded part of the skeleton (1〇); Waterjet cutting: Please refer to the fourth figure, according to the length of the required crank, use the waterjet to cut the skeleton (1〇) to blow the inlet. (13) end, and cut the skeleton (1〇) out of the 200846243 two embedded parts (14); carbon fiber cloth winding: please match the phase shown in the fifth to seventh, cut before the waterjet The second member of the second embedding unit (14) is the second tube (15) of metal material, and then one-way The fiber cloth winding frame (1)) and the first and second tube members (12, 15) are preferably structured by the unidirectional carbon fiber cloth (16) to increase (i ◦) with the first and second tube members (1), 15) Combination strength; preliminary hot pressing: heating and pressing skeleton (丄〇) to make carbon fiber cloth (i 6 ), pipe and skeleton (10) high temperature setting; slave fiber patch. The skeleton of most structures has been completed (i Q) The carbon fiber patch is attached to the outer surface. Since the skeleton (1〇) has been used to provide the crank shape, the carbon fiber patch is quite simple; the hot press molding. The heating skeleton (i Q ) makes the carbon fiber and the skeleton (^(6) The high-temperature setting, such as the completion of the bicycle crank manufacturing method of the present invention, and the completed curved phase (2)) finished the same as shown in the eighth to the tenth, the curved phase (2 〇) is a hollow structure, not only more Lightweight and the structural strength of the S and crank (20) is good, and the steps of the Qianwei patch are quite simple. Please refer to the tenth-riding indication, which is the same as the first embodiment, and the main method flow is the same as that of the first embodiment, and will not be described again, and the following only refers to different structures. In order to make the bicycle crank manufacturing method of the invention more convenient in the process, the step of setting the pipe fittings can be extended to 'form the bones of the unbrided pieces first, and then the carbon fiber cloths are wound to select the required specifications. In Guanxian County, the carbon-aged mixed parts and bones are carefully defined to increase the complexity of the process, and the New Zealand has its own power. The foregoing is merely illustrative of the preferred embodiments of the invention, and is not intended to be Any modification or change relating to the invention of the present invention 8 200846243 is included in the scope of the transfer. In summary, the bicycle crank manufacturing method of the present invention is completely in line with the development of the structure in terms of structural design, practicality and cost effectiveness, and the disclosed structural invention also has an unprecedented touch structure. The so-called "new carving" should be undoubtedly considered, and the invention can be more effective than the tu", so it is also "progressive", which fully complies with the requirements of the invention patents in the Chinese Patent Law. Please file a patent in accordance with the law, and please ask the fishing bureau to review it early and give it affirmation.
