Description
Technical field
The invention belongs to metal material processing technical field, is related to a kind of preparation method of high-precision titanium copper composite bar.
Background technology
The manufacture method of titanium and copper composite bar is mainly using being the manufacture methods such as explosion composite method, hot extrusion method at present, titanium copper
The standard GB/T of compound bar/T 12769-2003 are exactly that a diameter of 20-60mm circles titanium is manufactured using above-mentioned manufacture method
Copper compound bar, 20mm small-dimension titanium and copper composite bar is less than for diameter, China there is no corresponding national standard, technology not into
Ripe and prepared titanium and copper composite bar precision is not high.
The surface treatment of titanium tube, there are three different technologies at present：When annealing and pickling, the heat-treatment of annealing after cold rolling, then
Hydrofluoric acid and nitric acid acidwashing are carried out, allows its surface to lose silvery white gloss；Second, vacuum annealing, carries out vacuum annealing after cold rolling
Processing, and after being straightened, make its surface that there is metallic luster；Third, decorative pattern extrudes, on the basis of annealing and pickling, machinery is utilized
The mode of extrusion molding, the tangible decorative pattern of various bumps is formed in tube surfaces.Current so-called mirror finish, there is polishing, electricity
Two kinds of solution polishing, polishing are with the sand paper on polishing wheel, tube surfaces is formed minute surface, this method at a high speed on polishing mechanical
Waste time and energy, and surface roughness is very high, more than 8 μm, minute surface is relatively fuzzy；Electrobrightening is to be carried out on the basis of polishing at electrolysis
Reason, can form glossy surface in the short time, single pair large area part, to realize that uniform mirror finish is hardly formed, because titanium is easy
Oxidation, it is therefore necessary to apply high pressure, electrolyte can form oxide-film in moment in addition, and relatively hazardous, so typically seldom adding
Work sector application.
The content of the invention
It is an object of the invention to provide a kind of preparation method of high-precision titanium copper composite bar, solves titanium and copper composite bar material
The problem of surface accurate degree is low, roughness is insufficient.
The technical solution adopted in the present invention is a kind of preparation method of high-precision titanium copper composite bar, specifically according to
Lower step is implemented：
Step 1, from meet the titanium tube of standard requirement, red copper bar is as blank；
Step 2, copper rod is through in titanium tube；
Step 3, graphite is uniformly applied to titanium tube outer wall and dried；
Step 4, titanium copper rod is put into electric furnace and heated, temperature is ensured between 700 DEG C -800 DEG C, is incubated 1 hour, supporting
Suitable mould carries out drawing；
Step 5, burr, the crackle for removing titanium copper rod surface, cut off the position of titanium copper two end face out-of-flatnesses of rod；
Step 6, polishing processing is carried out, until the surface roughness of titanium copper rod is 8 μm or so.
The features of the present invention also resides in：
Equadag coating thickness is 0.2-0.4mm；
Drawing passes sizing reduction is 1.4-1.8mm；
Polishing processing is that bar is roughly ground and refined using grinding machine, reaches finished size requirement.
The beneficial effects of the invention are as follows by the titanium tube surface of titanium and copper composite bar coat graphite linings, in titanium and copper composite bar table
Face forms layer oxide film, can improve the combination property of tubing, by strictly choosing blank, titanium and copper composite bar outer surface is entered
The operations such as row heats, finishing and polishing processing, obtained titanium and copper composite bar precision is high, and roughness is good, up to 0.8 μm with
Under.
