Description of the Invention (/) The present invention relates to a method for manufacturing a counterweight base, especially a type of processing ® with a small volume, short processing time, which is conducive to mass production, and only requires partial turning, so it is suitable for Manufacturing method of base with irregular shape substrate. As shown in the third picture, it is a kind of La. A support frame for eight speakers includes a base (7 0) and a support rod (7 1) screwed on the aforementioned base (7 0); wherein: the upper end of the support rod (7 1) is connected to the speaker (7 2) . It is proposed here that the discussant is the aforementioned base (70). Because the shell of high-quality speakers (7 2) is mostly wooden, and the internal speakers, the weight is very considerable, and the current popular multi-channel audio, because multiple speakers are used at the same time, and to emphasize stereo, some speakers are The aforementioned support frame is used for elevated. Under this condition, the base (70) of the aforementioned support frame must have a considerable weight, in order to ensure that the loudspeaker (7 1) at the upper end of the support rod (7 1) does not shake or fall due to the unstable center of gravity. Therefore, the aforementioned base (70) is mostly made of heavy metal, and the further specific structure is as shown in the fourth figure. The surface of its base (70) is convex arc shape, and its inner bottom surface is relatively concave arc shape. And the base (70) contacts the ground only with a ring-shaped structure around the bottom. As for the manufacturing method of the base with the aforementioned space type, it can be roughly divided into two types at present: Casting: Design and manufacture the mold for the shape of the base to be produced first. Demolition of the base mold in the mold, followed by "cutting repair", "molding" and other steps, and finally complete the car repair, surface treatment and other final processing procedures to complete. Hot forging (Forging): It is formed by cutting and sawing rod-shaped substrates. 3 paper sizes are applicable to China National Standard (CNS) A4 (210 X 297 mm) ---------- --- t (Please read the notes on the back before filling this page) Order · --------- line, 512644

Description of the invention (a) The blank is sent to a heating furnace to be heated to a certain high temperature. After preliminary shaping, it is sent to the hot forging machine for forming. After the forming is completed, Γ is cut and repaired. " , "Forming" and other steps, and finally after the comprehensive car repair and other processing steps to complete. Taking casting as an example, it is one of the oldest manufacturing methods of metal models. The disadvantages of this technology are that the process is complicated, and the hardness or grain structure of the metal has not changed during the casting process. No improvement effect. The prototype after washing and casting must be fully repaired, and its processing area is large, which results in long processing time and difficulty in mass production. The advantage of hot forging compared to casting is that it can make the grains of the material change with the shape, so the strength of its corners and thinner areas can be improved. Under the action of oscillation and pulse motion, it has a better recovery. force. However, upsetting forging still has the same disadvantages as casting. For example, the base material prototype after hot forging has a large processing area and a long processing time. For large-scale production, the efficiency is difficult to be greatly improved, so Lack of competitiveness. In addition, due to the large processing area, in addition to circular shapes, such as oval or other irregularly shaped chicks, its overall turning has significant difficulties. From the above, it can be known that the base of the existing speaker support frame can be made by the existing casting or forging methods, but both have problems such as complicated processes, large processing area, long processing time, and difficult mass production. The method of making the U of the base needs to be further reviewed and a feasible solution is sought. Therefore, the main object of the present invention is to provide a base manufacturing method that can reduce the production of processed surface and shorten the processing time to facilitate mass production.
