Abstract
The invention relates to the field of a technique for producing a titanium-copper compound wire. The invention has the technical proposal that the technique comprises the following steps: selecting a titanium or titanium alloy pipe in proper dimensions meeting the national standard as a sleeve pipe (1); selecting a copper rod matching the dimensions of the titanium pipe as a rod material (2); penetrating the rod material (2) into the sleeve pipe (1), and attaching the rod material (2) to the sleeve pipe (1) by using an explosion compounding method to make a titanium-copper compound rod and form a titanium-base compound layer (3); and swaging the titanium-copper compound rod, and drawing to make the titanium-copper compound wire. The titanium-copper compound wire has the advantages of high bond strength, high surface smoothness and high quality of finished products. The invention changes the current unfavorable situation that the high-quality titanium-copper compound wire in China still highly depends on import, and enjoys favorable economic benefits.
Description
Technical field

Summary of the invention
The manufacturing process that provides a kind of titanium-copper composite wires to be solved by this invention, make layer of titanium metal and metal copper layer fit closely, the titanium copper bond strength is high and not easy to crack, can utilize existing equipment to realize the production domesticization that high-quality titanium-copper composite wires is produced, develop and expand the application market of titanium-copper composite wires rapidly, reach foreign exchange earning, obtain the effect of the stronger market competitiveness and good economic benefit.
The present invention is for solving the problems of the technologies described above, and the technical scheme of employing is:
The implementation process of manufacture method mainly is divided into the following step:
A) blank is prepared: select for use the certain size titanium alloy tube that meets national standard or titanium pipe as sleeve pipe (1); Select for use with the corresponding copper rod of casing inner diameter size as bar (2);
B) poling carries out sleeve pipe (1) inner surface and bar outer surface (2) the oil removing cleaning, cleans and refresh, then with in bar (2) threading (1);
C) blast is compound, and it is compound to adopt the blast composite algorithm that the sleeve pipe (1) that penetrates bar (2) is exploded, and makes sleeve pipe (1) and bar (2) fit together, and makes to form titanium copper composite bed (3) between sleeve pipe (1) and the bar (2), makes titanium and copper composite bar;
D) processing of swaging is heated to the processing of swaging after the uniform temperature with titanium and copper composite bar, is processed into the titanium and copper composite bar of certain diameter;
E) drawing will be heated to the titanium-copper composite wires that is drawn into required size after the uniform temperature through the titanium and copper composite bar after the processing of swaging;
F) finishing is removed burr to the titanium-copper composite wires outer surface that drawing is made, and reconditioning scratches, and excises two terminations, makes the titanium-copper composite wires finished product.
Wherein, step d) can adopt rolling, titanium and copper composite bar is heated to the titanium and copper composite bar that is rolled into certain diameter after the uniform temperature.
Be 600--720 ℃ for sleeve pipe (1) for the processing temperature of swaging of titanium alloy tube in the step d).
Be 600--650 ℃ for sleeve pipe (1) for the processing temperature of swaging of titanium pipe in the step d).
Step d) is 400-500 ℃ for sleeve pipe (1) for the rolling heating-up temperature of titanium alloy tube.
Step d) is 350-450 ℃ for sleeve pipe (1) for the rolling heating-up temperature of titanium pipe.
The invention has the beneficial effects as follows, the titanium-copper composite wires that adopts the present invention to make, the titanium copper metal level is fitted firmly, the yield rate height, the surface smoothness height, the titanium copper section is even, can utilize existing equipment to realize the production domesticization of titanium-copper composite wires as early as possible, both satisfy domestic market demand, and can export goods and earn foreign currency again, created good economic benefit.
