Description of the invention: The field of technology street to which the invention belongs is particularly referred to as an aluminum ring casting. The present invention relates to a method for manufacturing a forging and spinning of an automobile. [Prior Art] As shown in the figure, the wall manufacturing process of the conventional rim generally includes the following steps: 1. Extrusion of a bar 1. The bar 1 is gradually formed into a shape by using different forging dies of the array - 2. Using a plurality of forging machines (Fig. 2, 3, 4 are not shown, multi-pass forging, rim coarse embryos 5. 2. Heat treatment) The rim rough embryo 5. The embryo 4, using a spinning device to form a crotch portion 501. 6 Spinning the rim rough embryo 5, making the rim coarse and mechanically milling the rim rough embryo 5 0 solid disk surface (_ _ 'spoon 4 small days T), and turning the rim wall of the rim rough embryo $ (time-consuming, 'spoon '3-5 minutes)' to make the rim rough embryo 5 It is a rim finished product 7 with several rib arms 701. Although this process can achieve the purpose of manufacturing the finished rim 7 of the rim, in the actual manufacturing process, the process has the following defects: It is directly forging the solid bar 1 into the wheel ^ 5 Therefore, this process requires multiple passes of forging to form the order: the rim of the rim 5' is forged in every pass, such a process Both the boring machine and the group forging die are required to forge the forging embryo, and, due to the rim of the ring 200906511, the disk surface of the embryo 5 is impervious from 昝m , , ~ Shape, so the final forging machine is more to produce the largest output of the large forging machine, in addition, the forging embryo between the passes also need to use multiple twisting ..., furnace to repeat heating 'and By using the wheeling equipment for transportation, it can be seen that such a process sheet requires a large amount of manufacturing equipment in the forging step, and the equipment investment cost is greatly increased. Second, the process needs to be formed by multi-pass forging. The rim of the rim is 5' and finally more "mechanical plus jade"! The rib arm of the rim of the rim of the rim is vacant (4 hours), so it will greatly increase the required Machining man-hours. 3. When forming large-size rims, if the material deformation is too large, it will exceed the allowable deformation of the material. Therefore, this process requires more heating and forging to form. Large-size rims make it difficult to form large-size rims. 4. The wrought plate surface of the rim rough blank 5 is generally solid or flat, so the process needs to be machined. Milling the rim The disk surface of the embryo 5 can be processed to produce the rib arms 7〇, which causes waste of milling material. However, if the rib arms of various patterns are to be formed by such a forging process, the shape of the disk is often caused by the shape of the disk. Too complicated, the material flow is restricted by the cavity during the forging process, resulting in insufficient filling defects and cannot be formed, or the forming load must be increased to overcome the predicament that the material flow is restricted by the acupoint. Therefore, this process will be required. The forging is completed by using a larger forging machine, and the equipment cost is increased. [Invention] Therefore, the object of the present invention is to provide a low investment cost of the equipment 200906511, a short processing time, and a large-sized aluminum ring and appearance can be manufactured. The invention relates to a method for manufacturing a forging and forging spinning of an aluminum ring with a flexible shape. The method for manufacturing a forging and spinning of an aluminum ring of the invention comprises: (A) preparing an alloy material comprising bismuth and magnesium. (B) casting the aluminum alloy material into an aluminum ring rough embryo, the aluminum ring rough embryo having a wheel disc formed with a plurality of rib arm rough shapes, and one connected to the end edge of the wheel disc and surrounding an axis The rim wall. (C) Forging the wheel of the thick ring of the ring, so that the rib arms are formed into a rib arm. (D) This solution is subjected to solution heat treatment. (E) Spinning the rim wall of the aluminum ring blank so that the rim wall forms a crotch around the axis. (F) aging heat treatment of the aluminum ring rough embryo. The above and other technical contents, features, and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments. 2 is a preferred embodiment of a method for manufacturing a forging and spinning of an aluminum ring according to the present invention. The manufacturing method comprises the following steps: Step 1: As shown in FIG. 2, an aluminum alloy material (not shown) is prepared. The alloy material comprises 3~6wt% by weight of bismuth, 0.4% to 0.7wt% by weight of magnesium, no more than 〇lwt% of copper, and no more than 0.12% by weight of iron, and the weight percentage is not more than 〇〇5 The percentage of % of heavy and heavy bismuth is not more than 〇〇5wt% of zinc, the weight percentage is not more than 0.05wt% of nickel, and the weight percentage is not more than 〇25% of the titanium. The remaining weight percentage of the aluminum alloy material is determined by aluminum. composition. In the present embodiment, the more the bismuth component, the better the aluminum alloy 200906511 fluidity (i.e., the ease with which the aluminum liquid is filled in the mold) and the compensatory properties (i.e., the aluminum product is solidified). When the aluminum liquid is replenished, and has a better surface thickness after casting, the higher the magnesium content, the more the alloy phase (MgaSi) precipitated after the heat treatment of the aluminum alloy material, and the more High strength. Step 2: As shown in FIGS. 2, 3 and 4, the aluminum alloy material is cast into an aluminum ring rough blank 10, so that the aluminum ring rough blank 1 has a wheel 11 formed with a plurality of rib arms 13 . And a rim wall 12 connected to the end edge of the wheel u and surrounding an axis X. In the present embodiment, the aluminum ring rough blank is cast in a low pressure manner or a gravity casting manner, and a disk surface ln of the wheel 11 of the aluminum ring rough blank is cast into a complex shape approximate to the final product. However, there is still enough forging deformation. Step 3: As shown in Figures 2, 5 and 6, the wheel 11 of the aluminum ring rough blank is forged, so that the rib arms 13 (see Figs. 3 and 4) are respectively formed into a rib arm 14' The forging ratio of forging is 3〇%~7〇%, and the forging temperature is 43〇C~480〇C. Step 4: As shown in Figure 2, the rough ring of the aluminum ring is 1〇 (see Figure 5, 6) After solution heat treatment, the aluminum ring rough embryo can be heated to 52 〇 1~54 〇 it and held for 4 hours to 8 hours, then water quenched. Step 5: As shown in Figures 2, 7, and 8, the rim wall 12 of the aluminum ring has been spun, so that the rim wall 12 is formed with an 环绕 环绕 around the axis Η. In the present embodiment, the rim wall 12 is spun by a spinning device 1 (illustrated by only one roller in the drawing), so that the rim wall 12 is plastically deformed and has a forging flow. Line, to strengthen the mechanical strength of the material (for example, tensile strength 200906511 step eight. As shown in Figure 2, the aluminum ring rough embryo j 〇 (see Figures 7, 8) is heat treated by heat treatment, which can be thick i 〇 口 mouth to heat (10). C ~ lake. c, and hold the temperature for 1 hour ~ 7 hours, then air-cooled. #itb 9' 1〇 shown 'after the above steps are completed, you can in the circle of the rough embryo A plurality of locking holes and a nozzle hole are formed in the wheel 11 of the 1 turn, and the wheel wall 12 is turned (usually takes only 3 to 5 minutes), so that the final product of the wheel can be produced. The ''seat from the above description' can further summarize the advantages of the present invention as follows: - This S is the first to cast the alloy material into a hollow ring of rough embryos, which is the day of the wheel 11 The disk surface (1) has been cast into a complex shape similar to the final product, and is vacant. Therefore, the present invention can greatly reduce the thickness of the ring 1G in the ring.

Second, the invention is to first (4) alloy material into a hollow ring of the original ring 1 〇 ' and then the wheel 11 of the touch rough embryo 1G • Therefore, the present invention only needs to perform the forging of the pass, and the forging of the rough blank of the running circle can be completed, and the present invention does not require time-consuming machining to machine the rib arms, so that According to the prior art, the invention can effectively reduce the processing man-hours required for manufacturing. = The first is to cast the (4) alloy material into a shape near the W circle rough embryo 10'. Thus, the invention only needs to be built to complete the cycle. Forging force m of coarse embryo 1G 2 200906511 The problem that the amount of material deformation exceeds the allowable deformation amount of the material does not occur at the time of forging', and it is suitable for manufacturing a large-sized aluminum ring. 4. The present invention first casts the aluminum alloy material. Become a hollow aluminum ring rough embryo 1〇, so that the disk surface ln of the wheel 11 produces a complex shape that approximates the final product. Therefore, the present invention can form the shape required for the disk surface 111 as needed during casting, and thus, the aluminum manufactured by the present invention. The finished product can not only have the quality of the forged product, but also have various appearances and modeling flexibility of the cast product. 5.
