DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method for manufacturing a pinch wheel, and more particularly to an innovative manufacturing method that utilizes cold forging to increase productivity, quality, and material cost. Method. [Prior Art] Basin pressing, in daily life, is often used in the use of a pinch wheel, especially in the key ring. The general method for manufacturing a bolting wheel includes a casting molding method and a stamping molding method; wherein: the casting molding method is to mold a molten metal into a sand mold, and according to the molding method, the casting method is required to be Turning the sand mold, then liquefying the metal, and then through the injection molding and mold opening process, the system = quite slow, and the finished product has many pores, so that the quality of 'not smooth enough is missing. In addition, the stamping method will produce sharpness at the punching and shearing, and this will cause the user's fingers to be vulnerable to cuts, which will generate a lot of waste after punching and also result in material cost. waste. In the case of Fuxiyuan, the inventors of the present invention have developed the present invention in view of the lack of the above-mentioned molding method, which has been assisted by years of manufacturing experience in related industries, and has been ingeniously researched and improved. SUMMARY OF THE INVENTION The present invention relates to a method for manufacturing a pinch wheel, which is an array die of a main forging machine, which is forged by a thin bolting wheel to shape its appearance, and then formed by stamping and forming. The through hole is combined with other components, thereby designing, making the selection faster and more convenient, enabling the effective increase of the production capacity, and the product quality is better = and the material can be charged during the molding process. According to this manufacturing method, the company has greatly improved the competitiveness of the industry. [Embodiment] First, please refer to the first to second figures, the implementation steps of the present invention (the plug rotor substrate (1) is placed on the cold forging machine, the lower mold (2), and The upper and lower molds (2) are provided with a cavity (21) for matching the outer shape of the bolting wheel, and after forging, the bolting wheel substrate (1) can be forged into a shape of a bolting wheel. The rough embryo (3) [as shown in the first step of the first figure and the first and second steps of the second figure]. @戽The coarse embryo formed with the shape of the pinch wheel is placed in another cold forging In the lower mold (4) above, the recess portion (31) is forged on both sides of the coarse embryo (3) (as shown in the second step of the first figure and the third step of the second figure). Following the blanking of the blank (3) of the recessed portion (31) into the stamping die (5), the opening (32) is punched out at the recess (31) of the blank (3) [eg The third step of the first figure and the fourth step of the second figure are shown as 0 (2) placing the rough blank (3) in another stamping die (6) to set the opening (32). The bottom end of the coarse embryo (3) punches out the through hole (33) to form the pin wheel The product (as shown in the fourth step of the first figure and the fifth step of the second figure). By the implementation of the above processing steps, the manufacturing process of the pin wheel can be made simpler and faster, and not only the generation of no air holes. The strength is better, and the occurrence of anti-waste of stamping burrs can be greatly reduced; thereby, the substantial benefits of product molding can be effectively improved. According to the above structure and embodiment, the author has the following advantages: The invention mainly utilizes the cold forging method to form the bolting wheel, and the bolting wheel blanking system can be effectively utilized in the process, and the stamping forming method is not used, and a lot of wastes are generated, so the cost of the material cost is incurred. The invention can be greatly saved. 2. The invention mainly adopts the cold-forging method, and the raw material of the pick-up wheel is forged by a plurality of sets of molds in sequence, so the manufacturing process is quite fast and convenient, and contributes to the improvement of the production capacity. 3. The invention mainly uses the cold forging method to form the finished product of the bolting wheel, so the finished product of the bolting wheel has the appearance of cold forging, and the appearance of the burrs of the casting method or the burrs of the stamping method is increased. In summary, the embodiments of the present invention can achieve the intended use efficiency, and the specific structure disclosed therein has not been seen in the same product. Fully in compliance with the requirements and requirements of the Patent Law 'Ling's application for invention patents according to law, requesting oxygen for review, and granting patents, it is really sensible. 1272144 [Simplified illustration] First: The second schematic of the invention Fig.: Flow chart of the molding process of the present invention [Description of main component symbols] (1) Substrate (2) Mold (21) Mold hole (3) Coarse embryo (31) Pocket portion (32) Opening (33) Through hole (4) ) Mold (5) Stamping Die (6) Stamping Die
