The invention discloses a pure titanium wire material for spectacle frame and a manufacturing method thereof. In the smelting process of pure titanium ingot, O element with weight percentage of 0 ~ 0.20 and Fe element with weight percentage of 0 ~ 0.26 are added. According to the strength σ0 of the original titanium sponge, the amount of Fe and O elements needed to be added for reinforcement is obtained, and then the amount of Fe and TiO2 added in the smelting process of pure titanium material is determined. After forging, rolling, drawing and annealing, pure titanium wire with controllable strength is prepared, which can meet the requirements of titanium wire properties for different parts of glasses frame. The invention adds the exact amount of Fe and O elements in the smelting process of the preparation of pure titanium material, controls the chemical element content in the pure titanium wire, thus realizing the accurate control of the strength of the pure titanium wire, controls the strength deviation of TA2 pure titanium wire produced in different batches within 40MPa, and produces the pure titanium wire with specific strength requirements.
Titanium materials due to high strength, corrosion resistance and other advantages and widely used in aerospace, aviation, medical and other fields, in recent years with the development of titanium production technology and the price has been greatly reduced, titanium materials gradually applied to civil industry, which the use of titanium preparation of glasses frame has entered the life of ordinary people. At present, the titanium materials used in glasses frames are mainly pure titanium and titanium alloy, due to the high strength of titanium alloy, processing and forming difficulties, and ordinary people's trust in the purity of precious metals, pure titanium wire in the application of eyeglass frames still accounts for more than 70% of the share.
In order to meet the requirement of mechanical properties of pure titanium wire for components of pure titanium frames and solve the problem of large fluctuation of mechanical properties of materials in the existing market products, the invention provides a pure titanium wire for spectacle frames and a manufacturing method thereof.
The technical scheme of the invention is to add O element with a weight percentage of 0 ~ 0.20 and Fe element with 0 ~ 0.26 in the smelting process of pure titanium ingot. The O element is added in the form of titanium dioxide powder, and the Fe element is added in the form of granular or clastic pure iron. The titanium ingot is forged, rolled, drawn, annealed and other processes according to the technology of the invention, and pure titanium wire with controllable strength is prepared, which can meet the requirements of titanium wire properties of different parts of the glasses frame.
