Embodiment 1

[0035] refer to figure 1 , In this embodiment, a metal shell is provided, the exterior surface of the metal shell has a texture, and the texture includes a plurality of linear strip-shaped grooves 1, and the multiple linear strip-shaped grooves 1 are arranged parallel to each other. Wherein, the “linear strip-shaped groove 1 ” mentioned herein means that the linear strip-shaped groove 1 is a straight line when viewed vertically from the appearance surface of the metal shell 5 .

[0036] combine figure 1 and figure 2 , the cross section of each linear strip groove 1 includes two opposite oblique lines 2 and an arc 3 connecting the bottom ends of the two oblique lines 2, both oblique lines 2 and arcs 3 are related to the cross section The vertical center line A in is arranged symmetrically, and the distance between the two oblique lines 2 gradually increases from bottom to top, and the arc 3 protrudes downward. It can be understood that a plurality of the cross-sections exte...

Embodiment 2

[0045] refer to Figure 5 to Figure 7 , in this embodiment, a method for processing the metal shell appearance surface texture for processing the metal shell 5 in the first embodiment is provided. The method for processing the texture of the exterior surface of the metal shell comprises the following steps:

[0046] S1. Place the metal casing 5 in such a way that the appearance surface of the metal casing 5 is oriented vertically (refer to Figure 6 ), and keep the metal shell 5 fixed;

[0047] S2, using cutter 4 to sequentially process a plurality of horizontal linear strip grooves 1 on the appearance surface of metal shell 5 (refer to Figure 7 ).

[0048] The metal shell appearance surface texture processing method can process the above-mentioned texture on the surface of the metal shell 5, and then can form a bright appearance effect with vertical lines on the appearance surface, that is, obtain a vertical grating effect. , the bright vertical lines change accordingly,...

Embodiment 3

[0062] Can refer to Figure 6 and Figure 7 , In this embodiment, a tool 4 used in the method for processing the texture of the exterior surface of a metal shell in Embodiment 2 is provided. This cutter 4 comprises cutter bar 6 and blade 7, and blade 7 is connected to cutter bar 6 and is arranged perpendicular to cutter bar 6, and the cutting part of blade 7 comprises two opposite inclined-planes and the arcuate surface that connects the bottom of two inclined-planes; Wherein , when the arbor 6 is oriented vertically and the blade 7 is oriented horizontally, the two bevels and arc surfaces are arranged symmetrically with respect to the horizontal central plane of the cutting part, and the distance between the two bevels gradually becomes smaller along the horizontal outward direction , the arc surface protrudes outward, that is to say, the cutting portion tapers away from the tool holder 6 .

[0063] Through the tool 4, the texture of the above-mentioned embodiment can be pr...

Abstract

The invention relates to the technical field of metal shell processing, in particular to a metal shell, an appearance surface texture processing method, a cutting tool and electronic equipment. Texture on an appearance surface of the metal shell comprises multiple parallel linear strip-shaped grooves, wherein a cross section of each linear strip-shaped groove comprises two opposite oblique lines and an arc for connecting bottom ends of the two oblique lines, the two oblique lines and the arc are symmetrical about a vertical center line in the cross section, a distance between the two oblique lines is gradually increased in a direction from bottom to top, and the arc is bulged downwards. The appearance surface texture processing method for the metal shell is used for processing the metal shell, the cutting tool is applied to the appearance surface texture processing method for the metal shell, and the electronic equipment comprises the metal shell. The texture can produce a bright vertical line appearance effect on the appearance surface, bright vertical lines change with change of viewing angles, that is, the positions of vertical gratings change accordingly, and fineness of the appearance surface of the metal shell is improved.

Description

technical field [0001] The invention relates to the technical field of metal casing processing, in particular to a metal casing, a method for processing an appearance surface texture, a cutting tool and electronic equipment. Background technique [0002] Existing metal casings (such as the casings of mobile phones and tablet computers) are mostly made of aluminum alloys, and the surface treatment of aluminum alloys is usually done after CNC machining, grinding and sandblasting, and then anodizing. Among them, the appearance surface of the aluminum alloy after sandblasting has a certain roughness, mainly because the sandblasting uses zircon sand / iron sand to bombard the metal surface, forming uneven textures on the metal surface, and oxidation micropores are formed on the surface after oxidation. Scattering under conditions. Such a treatment method for the exterior surface of the metal casing causes the appearance effect of the existing metal casing to be basically assimilat...
