Embodiment 1

[0030] refer to figure 1 , In this embodiment, a metal piece 5 is provided, the surface of the metal piece 5 has a texture. Wherein, the texture includes a plurality of spaced strip corrugations 1, and each strip corrugation 1 is arc-shaped as a whole and the plurality of strip corrugations 1 protrude toward the same direction, or each strip corrugation 1 is linear in shape and multiple The strip corrugations are 1 parallel. Also, as is known, the corrugations consist of alternately arranged grooves and protrusions.

[0031] to combine figure 1 and figure 2 , in this embodiment, each strip corrugation 1 includes a plurality of grooves 2, and each groove 2 includes two opposite first slopes 3 and a first circle connecting the bottom ends of the two first slopes 3 The arc surface 4, the two first slopes 3 and the first arc surface 4 are symmetrically arranged with respect to the vertical center plane A of the groove 2, and the horizontal distance between the two first slope...

Embodiment 2

[0037] refer to Figure 4 to Figure 6 , in this embodiment, a method for processing the surface texture of the metal part for processing the metal part 5 in the first embodiment is provided. The metal surface texture processing method comprises the following steps:

[0038] S1, rough machining the surface of the metal part 5;

[0039] S2, finishing the surface of the metal part 5, processing the surface into a flat bright surface;

[0040] S3, the workbench 6 that is fixed with a plurality of metal pieces 5 rotates around its rotation center o (each metal piece 5 all does the revolution around the rotation center o of the workbench 6), and simultaneously the cutter 7 moves up and down on each metal piece An arc-shaped strip corrugation 1 is processed on the surface of 5, wherein a plurality of metal parts 5 are symmetrically arranged around the rotation center o, and the cutter 7 only moves up and down without rotation and revolution;

[0041] S4. The workbench 6 moves horizo...

Embodiment 3

[0052] In this embodiment, an electronic device is provided. The electronic device includes the metal part 5 of the first embodiment above, and the metal part 5 is a metal casing of the electronic device. The surface of the electronic device forms an appearance effect with bright vertical lines, and as the viewing angle changes, the bright vertical lines also change accordingly, thereby improving the fineness of the surface of the electronic device.

[0053] Preferably, the electronic device can be a mobile phone, a tablet computer and the like.

[0054] Preferably, the metal part 5 is an aluminum alloy battery cover of a mobile phone. Both sides of the aluminum alloy battery cover include curved surfaces. The above-mentioned texture can extend to the curved surface area to ensure the consistency of the overall surface effect of the aluminum alloy battery cover and improve the fineness of appearance.

Abstract

The invention relates to the technical field of machining of metal pieces, in particular to a metal piece, a machining method for surface veins of the metal piece and electronic equipment. The surface veins of the metal piece include multiple spaced strip-shaped ripples; each strip-shaped ripple is overally arched; the multiple strip-shaped ripples are projected in the same direction; a groove of each strip-shaped ripple includes two first inclined surfaces, and a first arc surface for connecting the two first inclined surfaces; the two first inclined surfaces and the first arc surface are symmetrically arranged about a vertical center surface; the horizontal distance between the two first inclined surfaces is gradually increased from bottom to top; and the first arc surface is downwards projected. The veins are set to form a bright vertical line appearance effect on a metal surface; and along with change of an observing angle, bright vertical lines are changed, so that the surface fineness of the metal piece is improved. The machining method for the surface veins of the metal piece for machining the metal piece can machine out the veins on the surface of the metal piece. The electronic equipment comprises the metal piece.

Description

technical field [0001] The invention relates to the technical field of metal part processing, in particular to a metal part, a method for processing the surface texture of the metal part and electronic equipment. Background technique [0002] The surface (especially for its appearance) of existing metal parts (such as mobile phone, tablet computer, etc.) is mostly made of aluminum alloy. The surface treatment of aluminum alloy is usually done after CNC machining, grinding and sandblasting, and then do Anodized. 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 surface of the metal part leads to the appearance effect of the existing metal part basically tending towards the assimilation sta...
