[0022] An embodiment of the present invention provides a method for processing a rear cover, combining figure 1 As shown, the processing method includes:

[0023] Step 101: Forging and pressing the metal plate to make a semi-finished back cover, the semi-finished back cover forms an accommodating space on the inner surface, and forms an appearance surface on the outer surface.

[0024] Wherein, the metal plate is made by extruding the metal blank. The metal sheet is preferably an aluminum alloy sheet. First, the metal sheet is forged and drawn according to the preset size to form the internal cavity size required by the rear cover, so as to form an accommodating space on the inner surface that can accommodate other components for installation and externally. The surface forms the exterior surface of the back cover semi-finished product.

[0025] Wherein, the manufacturing and forming process of the metal sheet is as follows: extruding the metal profile embryo to form a metal...

[0033] Further, combine image 3 As shown, a kind of processing method of back cover is provided in the present embodiment, and this method comprises:

[0034] Forging a metal plate to make a semi-finished back cover, the semi-finished back cover forms an accommodating space on the inner surface, and forms an appearance surface on the outer surface, wherein the metal plate is made by extruding a metal blank; The semi-finished back cover is subjected to aging treatment; the structural features and appearance features are processed on the semi-finished back cover after the aging treatment to form the back cover.

[0035] In the following, further descriptions will be made on the implementation steps further involved in the above method, and preferred implementation manners in the related steps.

[0036] Specifically, the structural features include antenna signal penetration slots for cooperating with the antenna installation and functioning. The back cover usually made of met...

Abstract

The invention provides a processing method for a back cover, the back cover and electronic equipment. The processing method comprises the steps of forging and pressing a metal sheet to prepare a semifinished product of the back cover, wherein an accommodating space is formed in the inner surface of the semifinished product of the back cover while an appearance plane is formed on the outer surface; the metal sheet is prepared by extrusion of an initial metal blank; performing aging treatment on the semifinished product of the back cover; and processing structural characteristics and appearance characteristics on the semifinished product of the back cover after the aging treatment is carried out so as to form the back cover. By adoption of the scheme, the raw materials can be reduced, the CNC (computer numerical control) processing time can be greatly shortened, and the cost can be lowered.

Description

technical field [0001] The invention relates to the field of preparation of electronic equipment components, in particular to a processing method for a back cover, the back cover and electronic equipment. Background technique [0002] With the continuous development of terminals (such as mobile phones), mobile phones become more and more fashionable. The aluminum alloy mobile phone back cover is more and more popular because of its rich anode color and good texture. How to reduce manufacturing costs while maintaining the expressive appearance of mobile phones has also become a problem for mobile phone manufacturers to consider. [0003] At present, this type of aluminum alloy mobile phone back cover is made of aluminum alloy sheet by rolling method, such as 5052 aluminum alloy profile series, after anodizing, there will be stripes on the surface of the sheet, which will affect the appearance of the mobile phone, and the product yield will be low. High, and the strength is ...
