Description of invention: [Technical field to which the invention belongs] :: Ming:: Subordinate to the two-extrusion technology of bicycle hubs - Sub-formation of peripheral decoration ί Economic benefits. Name material to enhance its [pre-existing technology of the invention], such as the first -, and the same private -. In the second round of the number of two wheels (1) the main group "where _ two:; == two: the plural spray The engaging teeth (12) are embedded and the blade is formed with a peripheral edge portion (20) to fit the fitting holes of the corresponding gear teeth (22) of the two hub projections j 1 ) so that the flanges of the two sides are flanged Department (2〇)) Both ends; and in order to improve the rim n-wheeled car and the shaft part (10) looking at the wheel hn Λ of Wu Guan, some of the industry will hope that the hole (15) disk edge nfn circumference formation Special Shaped Product Promotions Table 6) 'To absorb the attention of consumers, the tradition has three for the above-mentioned special shape wheel: one of them is drilled and formed. The second line is made by the clothing & method. In the case of the first type of drilling, the three types of forging are cut from the long round rod according to the required length, and the first step is to use the multi-head drilling machine to drill the plurality of decorative parts at the periphery to be equal angles and then drill the other royals. Zhou ^ 200827195 = (15) After drilling, and then the hub shaft (1 〇) two 钿 (〗 1) and the meshing teeth (12), and finally according to the two # V lose the axis Internode length, material waste problem, and the yield in the high port F Aberdeen, nor uniform sizes, so the processing efficiency; " ::: good 咼, uneconomical. The ugly cost plus the second model of molding, the system is, for example, after molding, it will be decorated with holes. 5) The trough shaft part (1 figure shows the embryo pulling, because the hub shaft part (1)) is thick (four) edge ^ 丄: This requires secondary processing to trim the mold line and the hair i, = into /, bit. The shaft end (丨丨) of the tooth (12), a cow's eve: the finished shaft part of the hub (10), making it a ‘transformer==electric: just just) by _. It has small pores and is easy to oxidize and damage. As for the third type of forging, it is shown in the fifth figure. After the long round rod is cut according to the required length, Xiang Forging molds and pushes one by one. 'Because it cannot be formed at one time, it needs to be forged by multiple forgings and formed at the circumference of the hub shaft (1〇).) Then, eight teeth D are formed at both ends of the hub shaft (1〇). (12) The shaft end (11) is finally processed to form a finished product with a decorative edge (16). Therefore, the processing efficiency is poor. Each of the aforementioned manufacturing technologies has different problems, and the production efficiency of 200827195 is extremely poor, and it is not economical: a large number of special-shaped decorative holes and costs are produced, and the bicycle can be improved and the sales volume can be improved. Xiu Yan attracts shoulder-payers. Pro: ί 深ί:: Human needle! The above-mentioned shaped wheel hubs are manufactured and experienced, and actively seek solutions. = 2 Research and development, and finally succeeded in the research of the times to overcome the poor manufacturing efficiency and high cost. [Summary of the Invention] 2 This invention is mainly for providing hunting to increase the speed of the process, and the yield is included, and the opening and closing of the vehicle is reduced. ... 'Akolang Province Materials' and the main body is composed of the following technical means, and the hub shaft part and the two-wheel valley flange part: the car...the wheel-wheel part of the hub shaft system uses the Ming extrusion molding technology Synchronizing with the circumference of the hub shaft portion to form an axially extending ornament and further improving the system by means of the following technical means, the hub shaft portion can be subjected to a secondary machining curve or a taper edge to allow the hub The shaft is made into various shapes of holes. (4) The weight loss of the shaft is further formed. The axial cross section of the 'valley shaft part can be various shapes. 200827195 It is the largest inner edge of the shaft of the hub. The diameter of the wheel can be the width of the opening of the circumference of the wheel. The groove of the hub can be separated from the shaft portion of the hub. The two ends of the hub shaft are machined to form a flange portion with a meshing tooth. The fitting hole of the tooth. The two cars are attached to the hub flange portion, and the hub flange portion can be formed in a body shape. Thus, by the specific implementation of the above technical means, the hub shaft portion can form various axial directions. Decorative hole, speed and yield of manufacturing And can save materials, and drop: = cost of production, further increase its added value, and can enhance the competitiveness and economic value of the product. With the following description of the pattern and the number of the figure, the period can make you expensive Review Committee 2: The scope of the invention's intention to protect. The fork white should still belong to this [Embodiment] If the second formation of the hole is the extrusion of the wheel, the valley shaft (10) and the two rounds of the valley ^ ^ (1) contain Yes - the hub flange portion (20) can be: "where /, the rim shaft portion (10) is separated or a 200827195 body shape; the features of the present invention are as follows, sixth, seventh and eighth As shown in the figure, the hub shaft portion (10) of the hub (1) is formed at one time by aluminum extrusion molding, and is formed at the periphery of the hub shaft portion (10) once to form an axially extending hole (15). 15) The section can be of various shapes, and the maximum diameter of the inner edge of the decorative hole (15) can be smaller than the opening width of the circumference of the opposite hub (J), and the shaft portion of the trough (1G) is formed by adding jade to the ends. 12) the shaft end (11), and the wheel flange portion (2) is also formed with a matching hole corresponding to the meshing tooth (22) 21), and = the shaft portion (10) can be secondarily machined to form various curves or 'X's decorative edge (16), so that the circumference of the hub shaft portion (1〇) further forms a special shaped decorative hole (15) ^ 'Combination constitutes a fast process, and the material-saving aluminum extrusion has the following advantages. The invention is practically manufactured and practical value: The process is fast. · Due to the integration of the extrusion technology, the axial direction is integrated. The hole (15) is not only required to form the hub shaft portion (1〇) one by one, but can be cut after the forming of the hub shaft portion (10), so the processing speed is fast and the synchronization is synchronized. The hole (1 5 ) can also reduce the process time, so it has the effect of improving production efficiency compared with the formula. 2. Reduce the cost: the hub shaft part (1〇) of the invention adopts the chipless aluminum extrusion molding technology, so It will not waste materials, the same, 200827195 =,: need, with high-cost equipment 'thus can significantly reduce, clothing costs, improve economic value. , Liang ΐ ΐ : Its size specifications _ forming molds 4 顼 right: not only uniform specifications, and high yield, compared to the existing 'village to improve production and financial efficiency. More shapes: as long as the extrusion molding die can be designed and shaped, the axial hole of the hub shaft portion (10) can form a corresponding shape, which is not easily restricted: it can meet the needs of different users and further enhance Product diversification and competitiveness. This is the above-mentioned numerous practical value 'Because === product is publicly used, so the invention has been in accordance with the invention patent.
