Abstract

The invention relates to a manufacturing method for an aluminum alloy shell. The manufacturing method specifically comprises the following steps that an aluminum alloy billet is processed into a blanking piece according to the preset size; the blanking piece is subjected to solid solution treatment, and a piece subjected to solid solution treatment is obtained; the piece subjected to solid solution treatment is subjected to forging forming, and a piece subjected to forging forming is obtained; and the piece subjected to forging forming is subjected to aging treatment, and the aluminum alloy shell is obtained. The temperature of solid solution treatment is 530+ / -5 DEG C, and the time is 2 h. The temperature of aging treatment is 200+ / -5 DEG C, and the time is 4 h. The temperature and time parameters of solid solution treatment and aging treatment are obtained after multiple-time cross-contrast tests, it can be ensured that the flatness and hardness of the aluminum alloy shell obtained through processing are good, and the yield strength of the aluminum alloy shell can also be improved; the aluminum alloy shell is not prone to deforming, and bad defects that stains occur after anodicoxidation can further be prevented; and the quality of the aluminum alloy shell obtained through the manufacturing method is good.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for manufacturing an aluminum alloy shell. Background technique [0002] With the rapid development of the digital electronics industry and the communication industry, the popularity of electronic products such as mobile phones, notebook computers, and digital cameras is increasing day by day, becoming necessary daily necessities for everyone.
