Description of the invention: [Technical field to which the invention belongs] The present invention relates to a bicycle pedal, and more particularly to a method for manufacturing a special pedal element for a bicycle. 5 [Prior art] As shown in the first figure, it is a special pedal (10) for a bicycle, including two clamping elements (11) (12), pivoted on a shaft (13), and a torsion spring篑 (14) keeps the two clamping elements (11) (12) in a stationary state at a set angle. The pedal (10) can be used for stepping on a bicycle-specific shoe. A sole of the shoe is provided with a metal piece (not shown). When the pedal is stepped on the pedal (10), the two clamping elements (Π) of the pedal (10) ) (12) The metal piece can be held quickly and easily, so that the rider can step on the pedal more stably, and less likely to miss it. As shown in the second figure, the component numbered (11) in the figure is formed by precision scale manufacturing, and its manufacturing process includes injection into a wax mold, dipping with sand, sticking and washing, pouring 15 slurry, casting, removing the finished product, repairing Steps such as grinding, which are cumbersome and time-consuming, lead to increased manufacturing costs and man-hours. As shown in the third figure, the pedal (20) is improved for the lack of precise abdomen production method. As shown in the fourth figure, the same components corresponding to the number 11 in the second figure are indicated by the number (21). , The woodwork (21) does not adopt the dewaxing casting method 20 production, and instead uses a die to go through multiple stamping procedures. As shown in the fifth and sixth figures, the component (22) in the fourth figure is produced, and the fourth is made by a lathe. The parts labeled (23) (24) in the figure are then joined together by welding (22) (23) (24). This production method has a short working time and can be produced quickly in accordance with the order. The disadvantage is that, as shown in the third figure (25) (26), the component (23) (24) -4- the component (22) is joined. There will be a gap in the part 此 'This: The gap (25) (26) ::: The lubricating grease sealed in the pedal (20), the pedal (20) is pressed at high speed and the temperature is warm, so that the lubricating grease is dazzling. When this happens, the gap ⑼⑽% is lost, which causes poor lubrication and affects product quality. SUMMARY OF THE INVENTION The object of the present invention is to provide a method for manufacturing a pedal component of a bicycle, which can be easily and quickly produced, and the component will not cause the pedal to leak oil, and can improve the quality of the product. In order to achieve the purpose of disclosure, according to a method for manufacturing bicycle pedals disclosed in the present invention, the method includes the following steps: a prefabricated two-end part, each of which has a round tube-shaped body and a larger outer diameter End, each side is provided with a joint surface; b. Prefabricated two-arm component, each end of the two-arm component has a joint surface; C. the two-end component is placed on the same axis line, sub-two The arm members are respectively attached to the two-end members by the joint surfaces of the two ends, and then welded and fixed into one body. Mouth surface [Embodiment] As shown in Figures 7-9, the embodiment of the present invention includes the following steps. Step A: Prefabricated two-end parts (31) (32) are made of metal vehicles, each of which has a circular tube shape. The body portion (311) (321) and an end portion (312) (322) having a larger outer diameter are provided on both sides of the end portion at an interval of 180 degrees-access (313) (323). Oral surface step B. Prefabricated two-arm part (33) (34) is formed by metal die, slightly -5- 1237611 has a gate shape, and the two ends of the two-arm part (33) (34) each have a joint surface (331) (341) ○ Step C: Place the two end members (31) and (32) on the same axis line, and respectively set the two arm members (33) and (34) with the joint surfaces (331) of the two ends thereof. 341) is in contact with the joint surfaces (313) and (323) of the 5 two-end component, and then it is welded and fixed into one body. This embodiment uses a set of special jigs (40) for operation, including: a first jig (41) 'is a long strip, and its cross-section is υ-shaped; A number of L-shaped notches (412) for the end components 10 (31) (32) to be placed; a second jig (42), in the shape of a long bar, with a number of grooves (421) The two-arm component (33) (34) is embedded so that the two joint surfaces thereof are opposed; the first jig (42) is placed between the two wall surfaces (411) of the first jig (41), so that the two-arm component (33) ) (34) of the joint surface (331) (341) and the two ends (31) (32) of the joint surface (313) (323) automatically guide the contact (because the end parts (31) (32) can be in situ Turn, 15 and the arm parts are embedded setting position, so the two end parts can be automatically guided by the joint surface of the two arm parts), and then a positioning member (43) (a bead in this embodiment) is used to cooperate with a plurality of locking members ( Bolts) to lock it in place, and then place a soldering material above the abutting joint surface of the two end parts (31) (32) and the two arm parts (33) (34) (in this embodiment, brazing is used), and then It is placed in a heating furnace and heated for 20 minutes, so that the welding material is heated and melted. Automatically moisten penetrating between the joint surface, then removed from the oven, let it cool down, i.e. fixed integrally element which as shown in the ninth icon number 30 structure. The manufacturing process of the invention is simple and fast, and the product quality is good, and there is no problem of oil leakage after assembling to the pedal of the bicycle, which indeed solves many shortcomings of the previous manufacturing process.
