Description of the invention: [Technical field to which the invention pertains] The present invention relates to an electronic product metal case and a method of manufacturing the same, 'particularly for forming a two-piece with a metal pipe member, and then forming the main body The shell member is cut to form a plurality of shell members (forming sheets = =) to form the electronic product metal shell member and a method of manufacturing the same. [Prior Art] #—Generally speaking, the manufacture of metal shell members of electronic products has conventionally been carried out by separately manufacturing each of the shell members, which may alternatively be manufactured by stamping, die casting or forging. The respective shell members usually include an upper casing cover, a lower casing, a battery casing, and the like. After the stamping, die-casting or forging process is completed, the shell parts which have been separately manufactured by _____ are subjected to general subsequent processing, such as burr processing, surface treatment, and the like. Finally, the processed shell members are sequentially assembled to form a finished metal shell. Although the electronic shell metal parts have been generally pre-manufactured separately, there are still many technical problems or technical disadvantages, so that the metal shell finished product still needs further improvement. The technical problems or technical disadvantages caused by the pre-existing manufacturing method of the conventional electronic product metal shell are detailed as follows. First of all, the conventional electronic product metal case must be assembled from pre-manufactured shell parts to complete the metal casing, so it inevitably creates technical problems with precision deviation between the various parts. In general, the precision deviation between the respective shell members includes the outer surface deviation, the inner surface deviation, the joint deviation, and the like. In particular, the surface deviation and joint deviation outside the shells seriously affect the appearance of the metal PKI0336 2007/S/lfi 5 — 1316429. The internal surface deviation of each shell may affect the assembly quality of the internal components. Therefore, the various parts of the metal parts of the conventional electronic products require additional processing operations to improve the technical problems of the accuracy deviation of the case parts. Thus, the manufacturing method of the various parts of the metal shell of the conventional electronic product has the disadvantages of making the complex, increasing the metal scrap and increasing the manufacturing cost. In addition, the traditional electronic product metal shell parts must be assembled from the pre-manufactured parts of the metal shell, so it is necessary to configure a sufficient set of technical problems to install; otherwise, it is not enough to strengthen the overall structure 'to decrease 16' It sounds its assembly quality. Therefore, the manufacturing method of each of the metal shell members of the conventional electronic product also has the disadvantage of being complicated in design. • In addition, the manufacturing methods of the various shell parts of the traditional electronic product metal shell parts must require the design, manufacture and subsequent processing of all the shell parts one by one. The processing may reduce the product yield of the final assembled product of the metal shell, so It also has the disadvantage that the process cannot be further simplified and the manufacturing cost cannot be further reduced. • As mentioned above, traditional electronic product metal parts require further improvements to improve the technical or technical shortcomings of their processes. In view of the above, in order to improve the above disadvantages, the present invention utilizes a metal pipe member for forming a main formed casing member, the main forming casing member comprising at least a forming unit, and then cutting the main forming casing member to form at least one forming member. The unit [shell unit], which is then formed into a metal shell. SUMMARY OF THE INVENTION The main object of the invention is to provide an electronic product metal shell and a manufacturing method thereof, which use a metal pipe to form a main forming shell, w 1 (1336 2007/4/lfi-6- 1316429 The main forming shell member is cut to form at least one forming unit, and the forming unit is a body-forming shell member, so that the turning has the effect of reducing the gold sample, improving the quality of the shell member and reducing the manufacturing cost. An electronic product metal shell member having a main housing and at least an assembly opening, the assembly opening being disposed on the main housing. The main housing $ is formed by a main forming housing member _ at least a forming unit, the main forming The wide piece has a connecting unit connected to the connecting pipe portion. The assembling opening is formed by cutting the connecting pipe portion. The main casing and the assembling opening are manufactured by the body forming method of the forming unit. In a preferred embodiment of the invention, the main casing is cut to form a lower casing cover and a battery casing cover. The step is as follows: (b) the good gold core is like the shirt making method, and the package element and the crucible: a 'the main forming shell Piece contains at least - forming sheet a connecting portion, the connecting tube portion is connected to the forming unit. The red silk shell member is cut, and the unit is made of at least one metal shell member. The early element is formed to be better than the present invention. Forming one less operating hole, in order to form the preferred embodiment, further cutting the formed single less than one cover. [Embodiment] In order to make the above and other objects of the present invention clear, the following adenoid BRIEF DESCRIPTION OF THE DRAWINGS The preferred embodiments of the present invention will be described in detail below, and will be described in detail with reference to Figure 1316429.

A metal hollow tube member is formed by forming a shape-domain shell member.丨, it is preferably a f-piece hydroforming (tube hydr〇f_ing) technique, a thermo-hydraulic forming process (w_f0rming), a tube hot-air pressure (-) forming technique, and an electromagnetic forming (EMFf〇rming) technique. When the pipe fitting hydroforming technology is adopted, a rolling fluid is added into the metal hollow pipe member, and the metal hollow and the pipe wall of the pipe member are expanded outward by the fluid pressure, and are inserted into the mold [body [not shown] to make the The main forming shell member 1. The cross-sectional shape of the metal hollow pipe member preferably includes a circular cross section, a square cross section, a rectangular opening/section, and other shape cross sections. Metal hollow tubulars can be extruded or welded. Hydraulic pressure required for forming metal hollow pipe fittings [I,000kg/Cm2]. ~ Tian (4) When shutting down the hydroforming technology, it is similar to the hydraulic forming of the pipe fittings. Only the high-pressure fluid (resistant to the Γ7 (nine) body) is added to the metal hollow pipe fittings, and the mold is heated. Pipe-to-temperature hydroforming operation 8 1316429 The temperature is formed by the metal material. At a temperature, a particular metal: again, for example, 300 C. At the same time, the two parts of the hollow tube are easily formed. The hydraulic pressure = shape technology required for the mold clamping pressure _ mold pressure is relatively lower than the pipe technology = with the ::::::: shape technology, it is formed with the tube side like air or inert gas == part of the high pressure gas [- ^ And the metal hollow pipe fittings and the mold are twisted.
