Description
Technical field
The invention belongs to metal material Field of Heat-treatment, more particularly to a kind of processing side of titanium or titanium alloy Bar Wire Product
Method.
Background technology
At present, the titanium or titanium alloy Bar Wire Product processing of diameter of phi≤10mm is general is all made Ф using continuous multistage hot deformation
The raw material bar stock of 10 ~ Ф 15.Main production process has following several：
<1>Stent drawing hot-working：The raw material bar stock removing oxide layer that strips off the skin eliminates hot rolling defect and bright metal watch is presented
Face, first with heating furnace heated oxide surface（Oxide layer is conducive to coat lubricant）, lubricated using heating stove heat, lubricant,
The stick silk material of different-diameter is produced by the fixing mould of different shaped jet holes, wire drawing machine drawing.Product basis in process
The size of working modulus, which needs to anneal repeatedly, eliminates machining stress hardening, and the surface surface eliminated and generated in drawing process that strips off the skin lacks
It falls into.Final finished needs its surface strip off the skin grinding or soda acid washes away lubricant contamination layer or oxygen except stick silk material surface
Change layer, can just produce bright stick silk material finished product
<2>Roller die cold drawing is processed：Mainly for Φ≤10mm raw material bar stock strip off the skin removing oxide layer eliminate hot rolling defect be in
Existing bright metal surface, using roller die and wire drawing machine, wire drawing machine drawing bar silk material drives roller die rotation to draw production different-diameter
Stick silk material.Product needs to move back vacuum fire elimination machining stress hardening next life repeatedly in process according to the size of working modulus
Produce bright stick silk material finished product
<3>More advanced finishing mill of high-speed wire rod mill uses big specification bar stock（Diameter of phi >=100mm）It is continuously rolled by hot worked mode
System is completed plus titanium or titanium alloy stick silk material, and which, which machines stick silk material and need to add using machine, to strip off the skin（Remove surface scale
And defect）, grinding, polishing, soda acid the finished product of processes completion surface-brightening such as wash, be surface-treated.
Chinese patent application No. is 201310096580.4, is related to a kind of titanium or titanium alloy rod hot rolling, wire rod high warm
Hubbing method.This method by blank heating to 950 DEG C -980 DEG C, rectify by hot rolling titanium or titanium alloy Bar material blank, cooling, peeling, heat
Directly, grinding prepares titanium or titanium alloy bar；Pyrographite stove lubricates, and hot pull is carried out by fixing mould under the conditions of 800 DEG C,
Drawing titanium silk, annealing, pickling, washing prepare titanium or titanium alloy silk.This method also belongs to fixing mould hot-pull technique scope.
Fixing mould hot pull needs heating furnace laser heating to improve material temperature（Not less than 700 DEG C）, blank surface connect
Continuous coating lubricant medium lubrication.There are lubricant mediums in drawing process to lubricate uneven phenomena such as causing surface tear, fracture of wire.Add
The pieces of bar stock surface oxidation of heat is serious, lubricant medium attaches seriously.Follow-up needs machine the scale removal that strips off the skin, pickling removes
Lubricant medium.Product surface inhales poor hydrogen, high energy consumption, execute-in-place environment, labor intensity height, low production efficiency.
Roller die drawing stick silk material, roller die cold drawing process principle are to draw stick in the pass of roll composition being freely rotated
Wire rod.By disk wire drawing machine drawing Bar Wire Product one end during cold drawing, by by blank frictional force drives roll rotation, roll hole
Type compressive deformation Bar Wire Product is molded.During the cold-drawn Bar Wire Product of roller die, due to want stress side based on molding Bar Wire Product, with drawing
Deflection is small in journey, the shortcomings of easily breaking silk material, low production efficiency, while also wants mating disk wire drawing machine.
Finishing mill of high-speed wire rod mill input is big（Apparatus value crosses hundred million yuan）, it is suitble to the public metal wire material silk material such as steel, applied to titanium
And this rare metal production of titanium alloy is very uneconomical.It also belongs to a kind of thermal processing method simultaneously, can not directly produce
Bright free of contamination finished product stick silk material.
Invention content

Source is lost, and reduces production cost；
It is 2. pollution-free：The present invention does not need to lubricant, cooling agent in process, and process does not need to heat, non-oxidation
Skin generates, and does not generate the influential pollutant on environment；
3. manual operation changes improvement：Existing hot-pull technique, blank drawing need to be heated to 700-800 DEG C, easily scorch or scald
Operating personnel.The present invention is cold working process, and there is no the above problems；
4. reduce corollary equipment：The present invention by from driving roller die cold rolling stick silk material, the operation of rolling do not need to as stent or
Existing roller die needs mating disk wire drawing machine to be drawn.
5. microscopic structure is good, more tiny than hot-working titanium or titanium alloy product grains, tissue is evenly.Cold working process is eliminated
Dynamic recrystallization in hot procedure is conducive to crystal grain refinement, improves structural homogenity, makes the metal microstructure more excellent.
6. the cold rolling titanium or titanium alloy stick silk material in a manner that motor drives roll, the operation of rolling do not need to disk wire drawing
Machine.
7. being heat-treated by the way of vacuum heat to stick silk material intermediate products and finished product, light extraction can be directly produced
Bright final finished.
8. the present invention can directly produce the finished product of surface smoothness Ra≤3.2 μm, finished product does not need to soda acid and washes, and will not produce
Raw the problem of product quality is influenced due to suction hydrogen.
