The strength of the teeth. ^ The above method is that the bicycle sprocket handles the two sides at a time, and the semi-finished material needs to be processed once to the enamel, which cannot be processed in a modular manner, and the cost of the inventory is relatively increased. The toothed disc of the bicycle formed by the powder metallurgy method of aluminum powder, because the bicycle changes the speed of the vehicle, the chain will move up or down on the toothed disc', and the side teeth of the tooth on the toothed disc generate a side pulling force, which makes the tooth tooth direction easy. The side crashes. The above-mentioned conventional bicycle toothed disc manufacturing method has the advantages of relatively low raw material cost, unevenness of the teeth, and the inability to modularize, and the lack of the side friction and wear resistance. 201221246 The present inventors have in view of this, that is, in the spirit of creation, thinking of different technical methods, and improving the present invention which is lacking in the present invention, and then applying. SUMMARY OF THE INVENTION The main object of the present invention is to directly forge and process aluminum blocks with low raw material cost, so that the strength of the teeth can be uniform 1 匕 1 and have modularity to reduce inventory. Cost and improve product wear resistance, and have uniform tooth side tension. In order to achieve the above object, the present invention provides a method for manufacturing a bicycle chainring, as follows: First, a relatively low cost aluminum block material is subjected to a hot forging process to make the relative stress of each tooth of the bicycle toothed disc relatively Uniformly, after an annealing treatment, the hardness is reduced, and then a stamping and blanking is performed, and the f-shaped region is further removed by the punching, and the ring-shaped region is retained, and then the annular region is given. The surface treatment forms a protective layer on the surface, and is subjected to a cold forging treatment, a heat treatment, a cold forging treatment, a heat treatment, forming a semi-finished product, and finally processing a finished product to improve the precision of the finished product. value. [Embodiment] Pre-step! The technical means for the construction and operation of the present invention will be described with reference to a few preferred embodiments and in conjunction with the drawings. It is believed that the objects, features and other features of the present invention are believed to be intensive and specific. 201221246 Please refer to the first to second figures. The method for manufacturing the toothed disc of the present invention includes: ',, the type of self-boring - hot forging treatment (1 〇): first hot-forging processing (10) Pressing the center outward diffusion method, (12), the hot forging treatment can use a lower cost aluminum block material to save cost, and the hot forging treatment (1〇) (More uniform, with the German system # ψ + + β J should be 以后 以后 以后 以后 “ “ 以后 以后 之 之 之 之 成品 成品 成品 成品 成品 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 Abrasiveness: An annealing treatment (20): through the heat treatment (2〇), the (= finished product hardness is reduced. 丄Ζ) 袈 a stamping blank (3 〇): will be 兮$ + 奋 ough (12) process ΛΓ 20 (20) after: "The stamping blank (30) is removed, retaining an annular area (3 a surface treatment (4 〇): the annular area of the stamping (3 2 ) 仏 ,, the lower part (3 0 ) after the layer protective layer.) ... surface treatment 'to make the surface formation = cooking (50): the surface treatment (4 〇) into a number of teeth, such as Self The gear teeth (52) of the toothed disc (51) have the effect of model setting. Heat treatment (60): The 201221246 process after the cold forging treatment (5 〇) is printed to form a solid solution after solid solution treatment. Method of treatment: A cold forging treatment (7 〇): After the heat treatment (6 〇), the finished product is subjected to the cold forging treatment (7 〇), which has the effect of shaping processing. A heat treatment (80): the cold forging After the treatment (7 〇), the finished product is treated by artificial aging after solution treatment. A finished product processing (9 〇): CNC machining is used to process the precision of one side of the finished product after the heat treatment (8 ◦). To increase the density value. 11 π Using the above processing method, a lower cost aluminum block (work 1) is processed through the above various processes to form a bicycle chain plate (5 1 ), since the aluminum block is Ii) Direct processing, the raw material cost is lower than that of the above-mentioned conventional calendering sheet processing. 8. The aluminum block (1 1 ) of the present invention is treated by the hot forging (1 〇) method, and the bicycle chainring can be used. (51) The teeth (52) are relatively uniform in relative stress and Homogenizing the side tension and improving the wear resistance of the product, it is not the same as the above-mentioned conventional extrusion treatment, the strength of a certain section of the teeth is less than the strength of the other section of the teeth, and the powder is not as conventional Metallurgical method, the round, not afraid of the key bar moving up or down on the toothed disc 5 movement =; force 'the tooth (5 2) is not easy to side collapse. And the invention is subjected to the hot forging treatment (1 〇 ), the annealing treatment (20) and the stamping blanking (3 〇) and the surface treatment (4 〇) are processed to form a semi-finished product, and then processed according to different specifications and sizes, and thus have a mold Grouped a total of 201221246 usability to reduce the cost of inventory. In summary, the present invention is in line with the provisions of the Patent Law, and is filed in accordance with the law, and is expected to grant patents as soon as possible.
