Abstract

The invention discloses a processing method for beta titanium alloy wires used for glass frames. The processing method includes performing cold drawing on beta titanium alloy wire blanks after surface treatment, performing center vacuum annealing after cleaning when processing rate is 50-60%, then carrying out cold drawing until the diameter is phi2.0-phi5.0, performing solution treatment, polishing, and finally obtaining the beta titanium alloy wires used for the glass frames. With the processing method, production efficiency is high, mass manufacturing is easy to realize, the beta titanium alloy wires are not oxidized during the whole processing procedure, acid and alkali treatment is omitted, and pollution on environment is avoided. The beta titanium alloy wires obtained from the processing procedure are high in accuracy, excellent in surface quality, high in elasticity and good in cold processing performances, and can completely meet the requirements on beta titanium wire used for the glass frames; the glass frames prepared with the beta titanium wires have the advantages of corrosion resistance, light weight, high elasticity and excellent weldability.

Description

technical field [0001] The invention relates to a processing method for a titanium alloy wire, in particular to a processing method for a beta titanium alloy wire for spectacle frames. Background technique [0002] β-titanium alloy is a research hotspot in the field of titanium alloy in recent years. The outstanding advantage of this type of alloy is that it has good cold formability in solid solution state and is easy to process into wire, rod and plate. β titanium alloy not only has excellent processing performance, but also has the characteristics of strong corrosion resistance, good biocompatibility, light weight, high elasticity and excellent weldability. Therefore, β titanium alloy wire is usually used as the first choice for preparing high-grade spectacle frames at home and abroad. Material. [0003] The β-titanium alloy wire used in the preparation of spectacle frames must have high-quality surface quality and excellent cold formability. The surface of the wire mat...
