Problems solved by technology

[0006] However, the CNC machining margin is reserved for the blank size in Scheme 1, which will lead to: 1. Increased cost of raw materials; 2. Increased tonnage of forging equipment and increased energy consumption; 3. Added a CNC clamping process, increasing processing costs
The use of recrystallization annealing in scheme 2 will reduce the strength of aluminum alloy

Embodiment 1

[0040] Please refer to figure 1 , which is a method flow chart of the first embodiment of a method for manufacturing an aluminum alloy battery cover provided in the specific embodiments of the present invention. As shown in the figure, the preparation method includes:

[0041] Step S101: forging and pressing the aluminum alloy plate to obtain a blank of the aluminum alloy battery cover.

[0042] Preferably, the aluminum alloy plate is a 7-series aluminum alloy material. The alloy composition of 7 series aluminum alloy materials is mainly zinc, but sometimes a small amount of magnesium and copper are also added. Among them, superhard aluminum alloys contain zinc, lead, magnesium and copper alloys close to the hardness of steel. 7005 and 7075 are the highest grades in the 7 series, which can be strengthened by heat treatment. The application range includes aviation (aircraft load-bearing components, landing gear), rockets, propellers, aerospace vehicles, etc.

Embodiment 2

[0051] Please refer to figure 2 , which is a method flow chart of the second embodiment of a method for manufacturing an aluminum alloy battery cover provided in the specific embodiments of the present invention. This embodiment is realized on the basis of Embodiment 1. As shown in the figure, the preparation method includes:

[0052] Step S201: Forging and pressing the aluminum alloy plate to obtain a blank of the aluminum alloy battery cover.

[0053] Step S202: performing incomplete recrystallization annealing on the forged blank in a vacuum environment.

[0054] Step S202 includes step S2021 and step S2022.

[0055] Step S2021: Start vacuuming when the temperature of the vacuum heat treatment furnace reaches the preset temperature.

[0056] Because the heat transfer mode of the vacuum heat treatment furnace in the vacuum state is only heat radiation, the efficiency is low, so, in order to improve the efficiency, the vacuum heat treatment furnace starts to vacuum when t...

Embodiment 3

[0063] Please refer to image 3 , which is a method flow chart of the third embodiment of a method for manufacturing an aluminum alloy battery cover provided in the specific embodiments of the present invention. This embodiment is realized on the basis of embodiment two, as shown in the figure, the preparation method includes:

[0064] Step S301: forging and pressing the aluminum alloy plate to obtain a blank of the aluminum alloy battery cover.

[0065] Step S302: performing incomplete recrystallization annealing on the forged blank in a vacuum environment.

[0066] Step S3021: Start vacuuming when the temperature of the vacuum heat treatment furnace reaches the preset temperature.

[0067] Step S3022: When the vacuum degree reaches the preset vacuum degree and the temperature reaches the preset incomplete recrystallization annealing temperature, perform incomplete recrystallization annealing on the forged blank.

[0068] Step S303: Carry out numerical control machine tool...

Abstract

The invention discloses a preparation method of an aluminum alloy battery cover, an aluminum alloy battery cover and electronic equipment. The preparation method comprises: forging an aluminum alloy plate to obtain a blank of an aluminum alloy battery cover; performing incomplete recrystallization annealing on the forged blank; The bit is processed by a CNC machine tool; the blank processed by the CNC machine tool is subjected to surface treatment to obtain an aluminum alloy battery cover. The invention realizes one-time forming of the appearance surface of the aluminum alloy battery cover by performing vacuum incomplete recrystallization annealing on the blank after forging, and saves the numerical control machine tool processing process of the appearance surface while ensuring the anodic oxidation performance of the aluminum alloy battery cover. , and retain the strength properties of aluminum alloy to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of electronic equipment accessories, in particular to a method for preparing an aluminum alloy battery cover, an aluminum alloy battery cover and electronic equipment. Background technique [0002] With the popularization of electronic equipment, especially smart phones, the spare parts industry has exploded. Stimulated by huge profits, various manufacturers have accelerated to seize the market share of spare parts. In such a situation, parts processing enterprises are required to update their own technologies, optimize processes and production tools, and reduce processing costs to gain a competitive advantage. [0003] At present, the preparation methods of aluminum alloy battery covers to avoid anode discoloration include the following two options: [0004] Scheme 1: Forging - stress relief annealing - CNC machine tool processing (Computer numerical control, CNC) including appearance surface, inner cavity...
