Abstract
The invention provides a method for forming a titanium alloy frame, comprising the following steps: providing a cylindrical titanium alloy rod. The titanium alloy rod is rolled to form the cylindrical titanium alloy rod into a flat titanium alloy. During rolling, the advancing direction of the titanium alloy rod is the longitudinal direction. The flat titanium alloy is divided to form a first material and a second material. The first material and the second material are respectively bent and machined for the first time to obtain the first frame and the second frame. The first frame and the second frame are assembled, and a second machining process is performed on the assembled first frame and the second frame to form a formed titanium alloy frame. Also provided are a titanium alloy frame and an electronic device. The titanium alloy frame forming method provided by the invention can solve the problem of material shrinkage during bending, reduce product waste loss, improve the quality of the titanium alloy frame, and ensure stable product quality under the condition of controlling low cost.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a titanium alloy frame, a forming method and an electronic device. Background technique [0002] The appearance of mobile phones is diversified, and the material of mobile phone frames is no longer limited to aluminum alloy, stainless steel, etc. Due to the advantages of low density, high strength, and corrosion resistance of titanium alloys, more and more manufacturers have begun to apply them to mobile phone frames. [0003] However, due to the poor plasticity of titanium alloys, in the process of bending and forming strip-shaped titanium alloy bars in the prior art, due to its poor fluidity, it has ductility during the bending process, and the material does not diffuse, resulting in There is a phenomenon of material shrinkage, which causes the product size to be out of tolerance, and even causes the product to be scrapped. Because of the high price of titanium alloy materi...
