Processing technology of titanium alloy mobile phone frame

Abstract

The invention discloses a processing technology for a titanium alloy mobile phone frame, which includes rolling and heat-treating a titanium alloy bar for twelve consecutive cycles to form a strip-shaped mobile phone frame semi-finished profile; the rolling process adopts at least one pair of rollers For producing titanium alloy rods, the rolling surface of the roll is provided with annular protrusions and / or annular depressions, the annular protrusions and annular depressions are concentrically arranged with the corresponding rolls, and the annular protrusions and annular depressions are consistent with each rolling The shape of the finished profile is similar to that of the shape; the heat treatment adopts a tube furnace, the heat treatment temperature is 600±20°C, the length of the tube furnace is 6 meters, and the speed of the titanium alloy bar passing through the tube furnace is 3m / min. The present invention abandons the previous method of CNC machining and uses rolling instead, which saves labor, material, time, materials, and has a good material-to-weight ratio. The method of multiple rolling and heat treatment solves the problem that TC4 titanium alloy is difficult to process and difficult to form. Rolling forms the semi-finished profile of the mobile phone frame, reducing the amount of subsequent engraving and processing into the mobile phone frame.

Description

technical field [0001] The invention relates to a processing technology of a titanium alloy mobile phone frame. Background technique [0002] The metal material used in traditional mobile phone cases is mostly aluminum alloy. With the advent of the 5G era and the improvement of people's requirements for the aesthetics of mobile phones, metal aluminum can no longer meet the functional design requirements of mobile phones due to factors such as signal interference and poor texture. And the psychological needs of consumers, so a new alternative material must be sought to make mobile phone cases. Titanium alloy has become the most important metal material for mobile phone cases in the 5G era because of its high specific strength, biophilicity, good sound permeability and good metal texture, and also symbolizes high-end atmosphere and other identity characteristics. [0003] The mobile phone case has complex shapes, small specifications and high dimensional accuracy. From the p...
