Explanation of the invention (2) When it is fixed, it cannot be bought with the current learned design and the invention, that is, the manufacturing method and concept are easy and the invention and its surface can be marketed. The "Aluminum alloy" situation is here, but the production of the invention produces a structural change of the invention, which reduces the front gap, but the consideration of the market demand is a dilemma. Its application in the low- and medium-priced bicycle market, aluminum alloys, and in this market segment, it seems that in terms of this market, items that can be felt at the price of iron are the best choice, but in fact, they must be selected. Mingren actively researched and improved the bicycle parts based on his many years of experience in bicycle parts, and finally aimed at providing a bicycle fork assembly system to obtain the appearance of the bicycle at a lower manufacturing cost. Before the provision of a bicycle and component manufacturing side, the plastic surface is covered with iron material and the skeleton is processed in the processing steps and the waste of man-hours. The technology, features, and effects used in the present invention will be described in detail with reference to the preferred embodiments and the accompanying drawings.

Description of the invention (3) Steps: a • Form a front fork skeleton 10 through processing of stamping, forging and welding of iron pipe fittings and plates; b. Initial burr of iron filings on the surface of the front fork skeleton 10 Clean it less, and then clean it with chemicals to remove oil breakage. C. As shown in the second figure, place the front fork skeleton 10 in the cavity 211, 221 of the injection molding mold 20 prepared in advance, and place it. D. As shown in the third figure, a plastic material of predetermined material and color is shot and covered on the outer surface of the front fork skeleton to form a plastic surface layer 40, so that the plastic surface layer 40 is integrally covered. Before that, the skeleton was 10; e • eject the mold and take out the finished product. For example, the first frame 30 is composed of components, and the shoulders are respectively placed in the rubber surface layer 40 as if they belong to the front wheel tube skeleton 50 to form a package of four, five, and sleeves 31, which are separated by injection. The OR part 34 is the sleeve 33 in the mold 20. The seventh and eight steering systems are separated from the plastic cover sleeve 33 with the special step described above, and the tube 31 is separated from the layer 40, such as the first layer 40. The first surface example, the shoulder 34, so I connect the plate 32, the fifth and the sixth figure, and finally can be transported with iron plus a plastic surface layer 40, the connection shown in the sixth figure The plate 32 and the components are combinable, such as separate sets, and then covered with a plastic watch and a shaft 35. As shown in the figure, the same handle bundle tube bundle tube skeleton 50 shape the beam tube step, which can be on the layer, the plastic and the shaft The rods 3, 5 and others can combine each of them as shown by _, which does not have to be covered with plastic. It can be used to make a bundle with the front. The iron front and skeleton surface can directly direct the surface of the front bone. Phase of each part

Description of the invention (4) Welding traces and sharp edges of the cutting position of each part are completely covered, so it can reduce the multiple processing steps such as grinding, polishing, and trimming necessary for the conventional iron forks, which can effectively save man-hours. In addition, the shape of the plastic surface layer depends on the design of the mold. There can be many different design designs under the same structure of the front fork skeleton. It is not necessary to prepare the raw materials of the front fork skeleton parts with different structural designs for different shapes like conventional ones, which can reduce The types of raw materials are prepared and the production control process is simplified, and the color pattern of the plastic surface can be arbitrarily changed. According to different customer needs and popular trends, different shapes and colors can be quickly changed under the same iron frame structure. Or, choose a plastic material with the same elasticity and density, which can quickly keep up with the popular steps and provide a bicycle with low manufacturing cost and beautiful and varied appearance. ^ In summary, the manufacturing method and structure of the bicycle front fork assembly of the present invention, which uses an injection molding method to directly cover the surface body of the iron fork skeleton with a plastic surface layer, effectively reducing the manufacturing process and manpower. — Waste ”can provide a bicycle front fork with a beautiful appearance and a change in shape at a lower cost, which is really industrially useful, and it has not been found in the relevant technical documents of the country and foreign countries. The same manufacturer took the lead first, so that the present invention has actually met the requirements of the invention patent, and has relied on the application. The method mentioned above is only one of the preferred feasible embodiments of the present invention. Therefore, the structural design for the application of this Maoming specification and the scope of patent application should be included in the patent scope of the present invention.
