Arc surface casing manufacturing method

The present invention relates to a method for manufacturing a casing, and more particularly to a method for manufacturing a curved casing, which reduces the production time and avoids waste of material of the sheet, thereby reducing the manufacturing cost.

The manufacturing method of the conventional casing is usually made by means of a punching device or a CNC machine. However, if you want to make a one-piece molded case with a curved surface, it is usually done by using a CNC machine.

However, the CNC machine can make a sheet into a one-piece curved shell, but the production is very time consuming and waste material.

In order to achieve the above and other objects, the present invention provides a method for manufacturing a curved casing, comprising the steps of: (S1) providing a plate; (S3) performing a first drawing of the plate to enable the The sheet has a first shell shape; (S5) at least three times of shaping the sheet having the shape of the first shell to deform the first shell shape into a second shell shape; (S7) Performing a first milling machine on the outer surface and edge of the sheet having the shape of the second shell to remove the burrs; (S9) performing a second milling machine on the inner surface of the sheet having the shape of the second shell to remove a burr; (S11) performing a second drawing process on the sheet having the shape of the second shell to produce a first curved surface; (S13) performing a third on the sheet having the first curved surface a second drawing process, wherein the first arc surface is deformed into a second arc surface, the arc of the second arc surface being greater than the arc of the first arc surface; (S15) performing at least the sheet having the second arc surface a fourth extraction project to deform the second arc surface into a final arc surface, the final Arc surface is greater than the second arc of curvature; and (S17) of the arc of the final sheet having at least one integral construction, such that the final sheet molding having a curved surface is a curved surface of the housing.

In the above manufacturing method, the material of the plate material is aluminum alloy 6063-T6.

In the above production method, the first drawing project, the molding project, the second drawing project, the third drawing project, the fourth drawing project, and the integer engineering department It is carried out by a stamping device.

In summary, the manufacturing method of the curved surface casing of the present invention reduces the time for manufacturing the curved surface casing by the above steps, and avoids waste of the plate, thereby reducing the manufacturing cost.

In order to fully understand the objects, features and advantages of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings.

Please refer to FIG. 1 , which is a flow chart of a method for manufacturing a curved surface casing of the present invention, which comprises nine steps. Hereinafter, how the manufacturing method produces a curved face casing will be described with reference to Fig. 1 and the text.

First, in step S101, a sheet to a stamping apparatus is provided. Among them, the material of the plate is preferably aluminum alloy 6063-T6, in order to facilitate the drawing work of the stamping equipment.

Next, in step S103, the sheet material is subjected to a first drawing process by the punching device to make the sheet material have a first shell shape.

Next, in step S105, the sheet material having the first shell shape is subjected to at least three molding processes to gradually deform the first shell shape into a second shell shape, and more specifically, the second shell. The body shape is closer to the shape of a curved casing than the first casing shape.

Next, in step S107, the sheet material having the shape of the second shell is moved to a milling machine, and a first milling machine is performed on the outer surface and the edge of the sheet having the shape of the second shell to remove the sheet. The outer surface and the edge of the burr to improve the smoothness of the outer surface and edge of the sheet.

Next, in step S109, a second milling machine is performed on the inner surface of the plate having the shape of the second casing to remove the burrs of the inner surface of the plate to improve the smoothness of the inner surface of the plate.

Next, in step S111, the burred-removed sheet is again moved to the stamping apparatus, and the sheet is subjected to a second drawing process to cause the sheet to produce a first curved surface.

Next, in step S113, a third drawing process is performed on the sheet material having the first curved surface, so that the first curved surface is deformed into a second curved surface, and the arc of the second curved surface is greater than the first The curvature of the arc.

Next, in step S115, at least one fourth drawing process is performed on the sheet material having the second curved surface, so that the second curved surface is gradually deformed into a final curved surface, and the arc of the final curved surface is greater than the second The curvature of the arc. Thereby, the arc of the final arc surface is closest to the arc of the arc surface of the arc surface casing.

Finally, in step S117, the sheet material having the final curved surface is subjected to at least one type of engineering to form the sheet material having the final curved surface into a curved shell. More specifically, by the integer engineering, the arc of the final arc surface is the same as the arc of the arc surface of the arc surface casing.

Although not shown in the figure, if the accuracy of the arc surface of the arc surface casing is to be improved, the number of times of the fourth drawing project may be increased in step S115 to improve the precision of the arc of the final arc surface. The sheet having the final curved surface is then formed into the curved shell by step S117.

In addition, since the manufacturing method of the present invention uses only the milling machine in steps S107 and S109, it is less time-consuming than the conventional method of manufacturing the curved casing using the CNC machine.

Furthermore, in the manufacturing method of the present invention, the sheet material having the shape of the second casing is formed into the curved surface casing by the steps S111-S117, so that there is no problem that the material of the sheet material is wasted.

In summary, the manufacturing method of the arc-shaped casing of the present invention reduces the time for manufacturing the arc-faced casing by the above steps, and avoids waste of material of the plate, thereby reducing the manufacturing cost.

The invention has been described above in terms of the preferred embodiments, and it should be understood by those skilled in the art that the present invention is not intended to limit the scope of the invention. It should be noted that variations and permutations equivalent to those of the embodiments are intended to be included within the scope of the present invention. Therefore, the scope of protection of the present invention is defined by the scope of the patent application.
