Description of the invention (1) The present invention relates to a bicycle frame. More specifically, it is said that: it is simpler to manufacture, can effectively reduce the processing process and reduce production: cost and beautiful appearance. Changing bicycle frame manufacturing method and 1 structure. According to the current market, all the frames on the market are made of metal materials, and the cheaper ones are made of iron. When using iron materials, the pipes, plates and pre-casted pipe joints (such as Wutong) are used. (Tube) Finished by stamping, forging and welding processing steps. Because the iron material has concerns about rust, the surface of the frame skeleton must be repaired in advance: detail processing: then 1 the frame skeleton electric ore or "Ground, so, has a more colorful appearance and is more durable, however, due to structural and processing constraints of the iron material frame, the traces of the welding parts of the frame are quite conspicuous, making it beautiful; In addition, after the cutting position of each part, it needs to be polished and polished, such as A, to complete the trimming process on the frame of the frame. The labor-intensive and labor-intensive platform does not have the competitive advantage in the industry. The advantage is only that the raw material price === higher quality frames are used more; of: the advantages of 2 pipe fittings and pipe joints == heavy = 'so, in addition to the shape, so in the shape: d: Have Some parts are cast to have no welding traces of the iron frame. The appearance is smoother and smoother, but you are also obedient to look at it. &Amp;, ... 3 aesthetic troubles. However, Ming Alloy etc. 480231 Explanation (2) Of course, the higher unit price aluminum alloy car will be applied to the low and medium price bicycles ^: 疋 market segmentation, but the aluminum alloy frame in this market segmentation looks like :: The consideration makes it possible to go at the price of an iron frame, and the market demand is the best choice, but the fact is: there are aluminum alloy frame texture options. In the present situation, the present situation is a dilemma. In view of this, the inventor of this case is actively based on his accumulated experience in manufacturing and manufacturing. Two: The car parts have the invention. After researching and improving, finally, the main purpose of the present invention is to provide a method and a structure that can be cheaper: the manufacturer of the book can easily change the shape of the shape to create a beautiful appearance and another object of the present invention In providing one: constructing the plastic surface layer: covering; and ^ can reduce the processing steps of the frame of the frame, effectively reducing = waves related to the technology, features and functions of the present invention, and an example of a good example, with detailed illustrations in conjunction with the drawings. . The invention is used in a bicycle frame, and the shape required by the frame is opened in advance, and it includes a male mold ^ according to the plate 22 'which is provided with a predetermined shape of a cavity 2U, 22m. First, please refer to the first figure, the present invention generally includes the following steps: a. Pipes and plates made of iron material are stamped, forged and welded, plus 480231. 5. Description of the invention (3) Formed by the process-frame skeleton 10, as mentioned above, the tube 12, the down tube 13, the sitting tube 14, and the rear upper = components, according to the different models, there may be differences between the components can be "connected into a body, and some shafts are movable; b. Clean the surface of the frame skeleton 丨 chemical to remove oil rupture; preliminary ... Then c. As shown in the third figure, the frame skeleton 10J glue is shot out of the mold 2. Mold In the holes 211, 221, and = = except for the solid coating: = open material: and the color of the plastic raw material is injected into the rubber surface layer 3. It is-a plastic surface layer 30, so that the plastic defect is covered on the frame skeleton 1 E. Withdraw the mold and take out the finished product. Because the volume of the frame is relatively large, in order to make it possible, the detachable part of the frame is divided into two parts in advance: I do n’t put it in the relevant mold. As shown in the fifth figure, the car I is covered with a plastic surface layer 3Q = injection ?: Shih 6! Step, which can be used in the The surface of the frame of the frame is “kneaded on the rubber surface.” This plastic surface layer can connect the frame bones to reduce the complete covering of the conventional iron edges. Due to the work steps, it can be effectively polished and trimmed, etc. Depending on the design of the mold, In η. ^ ^ The shape of the earthen clothing layer can have many types under the structure of the frame of the frame of the frame.
