preparation example Construction

[0058]The preparation method in the embodiment of the present application improves the existing deformation processing and heat treatment process, so that the whole or part of the surface of the aluminum alloy workpiece forms aluminum alloy grains that are visible to the naked eye and uniformly distributed; the surface of the workpiece is etched by a strong acid corrosion process , improve the contrast between different grains on the surface of the workpiece, so that the grain boundaries between aluminum alloy grains stand out. Using this method, the surface of the workpiece can form a "camouflage" texture locally or as a whole, thereby producing a novel appearance effect.

[0059] See image 3 , image 3 It is a schematic flowchart of one implementation of the workpiece preparation method of the present application. The method may include the following steps from S100 to S600.

[0060] S100: deforming the aluminum alloy billet to obtain a first aluminum profile.

[0061] ...

Embodiment 1

[0104] (a) The 6-series aluminum alloy 6013 is used as the raw material, that is, the aluminum alloy billet. Reverse extrusion is performed on the aluminum alloy billet to obtain the first aluminum profile. The process conditions of reverse extrusion are shown in Table 1.

[0105] (b) Putting the first aluminum profile into an aluminum alloy heat treatment furnace, and performing heat treatment according to the set conditions to obtain the second aluminum profile. The process conditions of heat treatment are shown in Table 1.

[0106] (c) Using the full CNC method, the second aluminum profile is pressed into the designed shape of the mobile phone back cover, and the mobile phone back cover is polished.

[0107] (d) soaking the back cover of the mobile phone in step (c) in a strong acid solution for etching. The etching process conditions are shown in Table 1.

[0108] (e) After the etching is completed, the back cover of the mobile phone is anodized. Anodizing treatment i...

Embodiment 2

[0110] The steps of Example 2 are basically the same as those of Example 1, only the specific process conditions of reverse extrusion, heat treatment, and etching are different, as shown in Table 1.

Abstract

The embodiment of the invention provides a workpiece of electronic equipment and a preparation method thereof. The workpiece can be applied in a shell body of the electronic equipment such as a coverplate or a mid-frame of a cell phone. The workpiece is made of an aluminum alloy material, wherein the surface of the workpiece is provided with at least one texture area, a plurality of texture plateblocks visible to the naked eye are uniformly distributed in the texture area, each texture block corresponds to one aluminum alloy crystal particle, and the color depth or gloss between the two adjacent texture blocks is different, so that a "camouflage" texture is formed. Such a workpiece surface may form a new appearance texture, thus avoiding the appearance of the workpiece or the electronicequipment applying the workpiece being too single in visual effect.

Description

technical field [0001] The present application relates to the technical field of material surface treatment, in particular to a workpiece of electronic equipment, a method for preparing the workpiece of electronic equipment, and an electronic equipment. Background technique [0002] In the field of electronic products (such as mobile phones, etc.), product appearance has become one of the important factors that determine whether consumers can purchase the electronic product. Electronic product casings made of aluminum alloy materials usually use sandblasting + anodizing, wire drawing + anodizing, bright polishing + anodizing to achieve the appearance effect. [0003] First, the aluminum alloy material is extruded to obtain an aluminum profile. Then, the aluminum profile is heat treated to improve the processing performance and mechanical properties of the aluminum profile. Then use the CNC machine tool to process the heat-treated aluminum profile into the shape of the pre-...
