[0022] Specifically, the preparation method of titanium alloy wire of the titanium alloy rivet material can be used, including the following steps:
[0023] A. After the surface of the φ8.0 ~ 12.0mm titanium alloy initial wire is treated, the vacuum-soluble retreat is carried out, and then enter the rotary and forged press, ceping forion to φ6.5 ± 0.2 mm;
[0024] B, then use the laminated roller mode brigadier, the wire for wound to φ6.5 ± 0.2 mm is used to φ2.0mm ≤ specifications <φ6.3mm, and the titanium alloy wire;
[0025] Among them, step A: When φ10.2mm <φ φ 12.0 mm, the initial wire is ≤ φ12.0mm, respectively, in a rotary forged amount to φ8.0 ± 0.2mm and a rotary water to φ6.5 ± 0.2mm When the vacuum solid removal treatment is carried out; when φ8.2mm <φ 10.2mm, when the initial wire is ≤ φ 10.2mm, the vacuum is performed at a rotary forged amount to φ6.5 ± 0.2mm, respectively. Treatment of dissolution; when φ8.0mm ≤ initial wire ≤ φ 8.2mm, when the rotary forged water is...

[0041] Prepare TB14 titanium alloy wires as follows:
[0042] A, the φ10.0mmTB14 initial wire produced on the direct high-speed wire roller is surface treated by the polishing manner, and the vacuum-soluble retreat is performed; the initial wire taper is then 60 ° at the inlet of the rotary force. , Low-speed enters the rotary force, rotate to φ8.0mm at 12 m / min, then vacuum-soluble retreat; then continued to rotate to φ6.5mm from 12 m / min, then vacuum solid Soluble retreat;
[0043] B, using a lifting roller mode brigadier to the φ6.5mm wire after the vacuum-soluble retraction, a reduction of 50 m / min to φ4.8 mm, then vacuum-soluble retreat; then continue to be reduced to Φ3.2mm, TB14 titanium alloy wire;
[0044] Among them, the conditions of vacuum solid solution in each stage are: vacuum annealing furnace, in the vacuum, no more than 3 × 10 -2 At PA, the wire is heated to 780 ° C, and the temperature is 5 h, and then the charge rate is 4Pa / h during annealing.

[0047] Preparation of TC4 titanium alloy wires as follows:
[0048] A. After the φ10.0mmTC4 initial wire produced on the direct high-speed wire rolling machine is used to surface treatment, the vacuum solid solution is performed; the initial wire is then fixed at one end card of the initial wire taper at the inlet of the rotary and forging machine. In the low speed enter the rotary force, rotate to φ8.0mm at 14 m / min, then vacuum-soluble retreat; then continued to rotate to φ6.5mm from the outlet speed of 14 m / min, then vacuum solid Soluble retreat;
[0049] B, using a lifting roller mode briger to the φ6.5mm wire after the vacuum-soluble retreat is reduced to φ4.8 mm at 48 m / min, then vacuum-soluble retraction; then proceed Φ4.0mm, TC4 titanium alloy wire;
[0050] Among them, the conditions of vacuum solid solution in each stage are: vacuum annealing furnace, in the vacuum, no more than 3 × 10 -2 Under the PA, the wire is heated to 760 ° C, and the temperature is 4 h, and ...
