Description
Technical field
The invention belongs to the processing and treating method technical field of titanium silk, is related to a kind of recrystallization annealing method of titanium silk, this
Invention further relates to the surface treatment method of titanium silk, further relates to the device for detecting titanium silk elasticity.
Background technology
The drawing of titanium silk material is machined with hot-working and cold working two ways, and hot-working blank is reached by the method for heating
To more than recrystallization temperature, the plasticity of material is good, then carries out drawing by stent, can obtain larger heat distortion amount,
Reach required size.Cold working blank carries out drawing by stent or roller die, is passed through in the presence of three-dimensional compressive stress
Mould, less cold deformation can be obtained, reach required size.No matter hot-working or cold working, after the process
The problem of material processing hardening all be present, cause that the grain structure of material is disorderly and unsystematic, aberrations in property is very big, it is general using heat at
The method of reason, by heating blank to more than higher recrystallization temperature, it is incubated the regular hour so that the crystal grain of material is replied
Recrystallization, crystal grain are also eliminated during annealing and added into isometric or other regular shapes martensites or austenitic state
Work is hardened, and the performance of material reaches unanimity.Made annealing treatment for turned blank, because the heat time lives forever thermal expansion chi after annealing
Very little increase " become fat " phenomenon, and oxide skin thickens, and causes size to be difficult to accurately control, has that annealing efficiency is low, energy consumption is big, behaviour
Make the problem of complicated.
Conventional black metal surface treatment technology is more ripe, but the process for treating surface difficulty of non-ferrous metal is very big,
Particularly titanium, it does not chemically react with general surface application agent, can not use conventional immersion coating processing side
Method；And most of physics coatings and titanium surface adhesion are also poor, it is easy to fall off in deformation after unloading process and rise not
To the effect of coating.
Titanium or titanium alloy material has good elasticity because modulus of elasticity is low, applied to commodity, sports goods, work
The various flexible members in the fields such as journey articles for use, make correcting shape of tooth, spectacle frame, earphone suspension member, adjustable spring, golf club head and hit
Beat the products such as panel.
The detection of titanium silk material elastic performance has two methods, and a kind of is the modulus of elasticity using special inspecting equipment to material
Detected, which testing result is accurate, but its costly, complex operation, the time is long, the personnel that need professional qualification enter
Row detection；Another kind be using hand vice it is one or many to titanium silk material sample break it is curved, break it is curved after and sample carry out contrast bending
Degree, small elastic good, the big explanation poor flexibility of degree of crook of explanation of degree of crook, which is easy to operate, differentiation directly perceived, efficiency
Height, but its operation is random, human factor influences greatly, it is impossible to elastic performance is accurately measured, is as a result also difficult to record and contrast.
The content of the invention
It is an object of the invention to provide a kind of recrystallization annealing method of titanium silk, solves thermal expansion present in prior art
The problem of size increases.
It is a further object of the present invention to provide a kind of surface treatment method of titanium silk, manages deposition with titanium surface formation and closes
System, is not chemically reacted with titanium, is not changed titanium chemical composition and mechanical performance.
Third object of the present invention is to provide a kind of elastomeric check device of titanium silk, and its is simple in construction, easy to operate.
The technical solution adopted in the present invention is the recrystallization annealing method of titanium silk, is divided into online annealing and individually annealing
Two ways, annealed suitable for the titanium silk material faster recrystallization of feed intake diameter or section thickness≤4mm；
For hot pull silk material, at the end of hot pull, using the lasting traveling of former wire drawing machine silk material, silk material is being sensed
Recrystallization annealing processing is carried out in heater online, sensing heating only carries out 0.3~0.5 second, about 100~250 DEG C fast
Speed heating thermal compensation, reaches blank technological temperature, obtains recrystal grain tissue；
For cold drawing silk material, the titanium silk material that cold drawing is completed is filled in sensing heating using independent take-up and pay-off device
Put inner traveling and individually carry out recrystallization annealing processing, silk material, induction heating apparatus carries out quick heating in 3~5 seconds, blank temperature
580~700 DEG C can be quickly raised, reaches blank technological temperature, obtains recrystal grain tissue.
Another technical solution adopted in the present invention is that the surface treatment method of titanium silk, above-mentioned again by the progress of titanium silk
Recrystallization annealing temperature, then surface acid-washing oil removing, is soaked in clear water and removes acid solution, is put into the composite coating agent prepared, heating
To 70-90 DEG C, 20-30 minutes are incubated, therebetween stirring coating agent, when the brown carbonized film of titanium silk table face appearance, are taken from coating agent
Go out, rinsed with 70-90 DEG C of clear water, remove sediment, cold water flush, hot blast drying.

Distilled water, 70-90 DEG C is heated to after mixing.
The third technical scheme of the present invention is the elastomeric check device of titanium silk, for by above-mentioned surface treatment
Titanium silk carries out elastomeric check, is mainly made up of fixing clip, clamp block, cylinder bearing, bend arm, dead man, the part of scale six；
Cylinder bearing axis are and coaxial with the center of rotation of bend arm perpendicular to plane of bending；Cylinder bearing is replaceable, cylinder bearing
Central shaft is adjustable so that sample contacts with the arc surface of cylinder bearing.
Preferably, 15~60mm of cylinder bearing diameter, the parallel distance 100mm of cylinder bearing axis to dead man center；It is suitable
For the detection that diameter or section thickness are 0.2mm~4mm titanium silk material room temperature elastic performances.
The invention has the advantages that the recrystallization annealing method of the titanium silk of the present invention, is detected using infrared thermometer
Preform surface temperature, infrared thermometer detection+induction heating equipment automation coordinated signals, silk material temperature can be with less than 50 DEG C
It is judged as cold drawing silk material, it is automatic that silk material recrystallization annealing temperature and speed are set, according to annealing temperature and the temperature of silk material temperature
Degree difference sets technological parameter, and quick heating carries out thermal compensation, reaches blank technological temperature.Because blank sectional dimension is smaller,
Less induction heating power can be utilized, induction heating equipment energy consumption, occupation of land are relatively little.At the surface of the titanium silk of the present invention
Reason method, there is non-reacted feature composite coating agent by the coating in titanium silk table face, can manage and deposit with titanium surface formation
Relation, do not chemically reacted with titanium, do not change titanium chemical composition and mechanical performance.A kind of drawing is can be used as to add
