Problems solved by technology

The method of manufacturing honeycomb small-hole shell in the prior art is mainly to open the hole with a hand drill, which repeatedly drills the honeycomb small holes on the metal shell through a hand electric drill. However, the method of hand drill opening is mainly controlled by hand. operation, so the opening is not accurate, there are many burrs, and the speed is slow and cannot be mass-produced

Embodiment Construction

[0007] In this embodiment, the method of manufacturing the porous housing is specifically described by taking the manufacturing of a porous housing of a portable electronic device as an example. Please refer to figure 1 The porous shell 1 includes a base 2 with a honeycomb-shaped through hole 3, and the through hole 3 is circular. The substrate 2 is a metal substrate with an anodic oxide film on its surface. The anodic oxide film can be colored in various colors as needed, and patterns can also be formed on the surface.

[0008] Manufacturing the above-mentioned porous shell 1 mainly includes the following steps:

[0009] (1) Punching;

[0010] (2) Stamping and forming;

[0011] (3) Grinding;

[0012] (4) Anodizing.

[0013] Among them, step (1) is to continuously punch the metal sheet through several punching stations. Each station is provided with at least one punching machine, each punching machine is provided with at least one punching die, and the upper die of each punching d...

Abstract

A method of making porous casing body comprising the steps of , perforating, forming by punching, grinding and anodic oxidation. The method provided by the invention can be applied onto the manufacture of porous housings for miscellaneous installations.

Description

【Technical Field】 [0001] The invention relates to a method for manufacturing a porous shell, in particular to a method for manufacturing a shell with a honeycomb-shaped small through-hole structure. 【Background technique】 [0002] Metal materials are widely used as the shells of various devices, such as the shells of mobile phones, personal digital assistants (Personal Digital Assistants), because of their easy processing, heat resistance, chemical resistance, wear resistance, higher surface hardness and better decorative effects. Digital Assistant, PDA) shell and portable calculator shell, etc. In order to satisfy consumers’ pursuit of visual effects, many manufacturers currently anodize the surface of the metal shell and color it into various colors, or spray various paints on the surface of the metal shell to form a color pattern, so that the metal shell has a better appearance. The decorative effect. If honeycomb-shaped small holes are formed on the surface of the metal shell...
