Description
Technical field
The present invention relates to a kind of titanium alloy wire material processing method, be specifically related to a kind of spectacle frame beta-titanium alloy silk material processing method.
Background technology
Beta-titanium alloy is the focus of titanium alloy area research in recent years, and the outstanding advantage of this class alloy is to have good cold formability under solid solution condition, is easy to be processed into a material, bar and sheet material etc.Beta-titanium alloy not only processing characteristics is good, have also that corrosion resistance is strong, good biocompatibility, in light weight, elasticity is high and the characteristics of excellent weldability, thereby both at home and abroad usually with the preferred material of beta-titanium alloy silk material as the high-grade spectacle frame of preparation.
Beta-titanium alloy silk material for the preparation of spectacle frame must have high-quality surface quality and good cold formability.Silk material surface requirements light has not allowed defectives such as crackle, scuffing, hole point, oxide skin.In order to guarantee good cold-forming property, the beta-titanium alloy spectacle frame is supplied with the solution treatment attitude with the silk material usually.The purpose of solution treatment is in order to be retained in the metastable phase that the high-temperature region obtains, and this tissue has moderate strength and higher plasticity, and cold forming is good.
Present domestic spectacle frame be mainly the fixed die hot-drawn with beta-titanium alloy silk material processing method or fixed die cold drawn.The hot drawn operation of fixed die is that kicker strips off the skin, oxidation, fixed die hot-drawn (graphite lubrication), atmosphere annealing and alkali pickling, and the titanium alloy wire materials surface contamination at high temperature of this kind processing method is serious, and the energy consumption height of tubular heater.The cold drawn operation of fixed die is that kicker strips off the skin, oxidation, silk base surface-coated lubricant, fixed die are cold drawn, atmosphere annealing and alkali pickling, and the work hardening of this processing method titanium alloy material is serious, needs constantly annealing in order to prevent fracture of wire, and production efficiency is low.Above-mentioned two kinds of processing methods all can produce thicker oxide layer on silk material surface, and the rough surface of silk material after the alkali pickling can not satisfy spectacle frame with the requirement of titanium alloy wire materials to great surface quality, and alkali acid production scene is abominable, causes environmental pollution.
Summary of the invention
The purpose of this invention is to provide a kind of spectacle frame with beta-titanium alloy silk material processing method, solved existing processing method and had that silk material surface quality is poor, production efficiency is low and environmental pollution problems.
The technical solution adopted in the present invention is, spectacle frame is with beta-titanium alloy silk material processing method, and beta-titanium alloy silk base is cold drawn through carrying out after the surface treatment, when working modulus during for 50-60% through cleaning laggard interline vacuum annealing, continuing to be cold drawn to diameter then is
After carry out solution treatment, polish again, namely obtain spectacle frame with beta-titanium alloy silk material.
Characteristics of the present invention also are:
Middle vacuum annealing is carried out in vacuum drying oven, and its technical process is: vacuum drying oven is vacuumized, and vacuum reaches 5 * 10
-2Be warming up to 750-800 ℃ after Pa is above, behind the insulation 30-60min immediately in the vacuum drying oven applying argon gas force cooling.
Solution treatment is to be with diameter
Beta-titanium alloy silk material successively by damping unwrapping wire, argon shield tubular heater, furnace temperature is a little more than transformation temperature, recirculated water cold trap and the adjustable admission machine of beta-titanium alloy, realizes the solution treatment of non-oxidation formula.
Surface treatment is that beta-titanium alloy silk base is not stripped off the skin and carries out surface finish at a Chiba wheel silk material polishing machine behind scale removal, rolling crack and the fold defect through being in the mood for lathe, removes strip off the skin detritus and spiral lamination.
Cold drawn is to carry out at the roller die wire drawing machine, and with wire drawing oil the roller die mould is lubricated.
Cleaning is in supersonic wave cleaning machine, is that washing agent and the composite cleaning fluid of hot water of 1:20 cleans beta-titanium alloy silk material with volume ratio, carries out rinsing with clear water, oven dry after removing surface and oil contaminant.
Polishing is carried out at belt sander, removes blemish and improves surface gloss.
The invention has the beneficial effects as follows:
1. spectacle frame of the present invention is with beta-titanium alloy silk material processing method; proceed cold drawn then by vacuum annealing in the middle of carrying out once after the beta-titanium alloy silk material after the surface treatment is cleaned when the roller die wire drawing machine is cold drawn to working modulus for 50-60%; every time working modulus can reach 20%-30%; total working modulus can reach 60%; the production efficiency height is easily accomplished scale production.
2. through cold drawn, intermediate annealing processing and solution treatment, oxidation does not take place in beta-titanium alloy silk material in the whole process, has avoided the alkali pickled surface to handle, and has avoided the pollution to environment with beta-titanium alloy silk material processing method for spectacle frame of the present invention.
The beta-titanium alloy silk material dimensional accuracy height that obtains with beta-titanium alloy silk material processing method processing of spectacle frame of the present invention, surface quality is good, elasticity is high and cold-forming property is good, satisfy spectacle frame fully with the requirement of beta-titanium alloy silk material, and with the spectacle frame of its preparation have corrosion-resistant, in light weight, elasticity is high and advantage such as excellent weldability.
