Description
Technical field
Field is remanufactured the invention belongs to machinery, and in particular to one kind strengthens repairing mine mechanical surface using optical-fiber laser
Method.
Background technology
China still faces resource constraint reinforcing, the situation that reply climate change pressure is increased, it is necessary to reduce resource from source
Consumption and waste discharge, realize resources effective utilization and recycle, and drive Green Development, low-carbon (LC) to send out by cycle development
Exhibition.With the peak period that China scraps into mechanized equipment, remanufacturing industry is excellent the aspects such as society, resource, environmental benefit
Gesture determines that development remanufacturing industry is imperative, remanufactures as national strategy new industry, carries out in a deep going way to remanufacture skill
Art research is increasingly urgent.Efforts To Develop is remanufactured and the research of correlation technique meets fundamental state policy, is benefited the nation and the people.
Mining machinery surface remanufactures successively has developed the method such as arc surfacing, plating, laser surface intensified.Arc surfacing
Generally welded using stick electrode or TIG, this method is simple to operate, flexibly, be relatively adapted to scene local damage reparation；But its
Low production efficiency, and electric arc thermal weld stress is larger, case hardness, wearability and corrosion resistance larger to matrix heat affecting
Can be restricted, it is limited that mining machinery remanufactures life-span raising.Although composite plating improves the performance of coating by some measures,
But similar with metal chromium coating, coating is still physical bond with matrix, and " bulge " and full wafer occurs in coating during use
Break-off is still present, and produces large quantity of exhaust gas, waste water in electroplating process in addition, causes larger environmental pollution, big with current
The green manufacturing that power is advocated runs in the opposite direction.And be then that effective solution is done using advanced high-tech laser fabrication technology
Method.
Laser processing technology shows as comprehensive integration laser technology, new material technology, computer and a Numeric Control Technology
For advanced manufacturing technology, the attention of countries in the world important research mechanism, university and enterprise and widely studied is obtained always.
Surface Hardening Treatment based on laser is to form certain thickness process layer in material surface using LASER HEATING, is changed
Mechanical property, metallurgical performance, the physical property of kind material surface, so as to improve part, the wear-resisting, anti-corrosion of workpiece, endurance etc.
A series of performances.Laser surface treating technology mainly includes laser hardening, laser melting coating, laser surface alloying, laser-impact
Hardening and lam etc., with advantages below：Energy transmission is convenient, can be selectively local to processed workpiece surface
Reinforcing；In energy active set, process time is short, and heat affected area is small, and workpiece deformation is small；The complicated workpiece for the treatment of surface configuration, and
And easily realize automatic production line；Modified effect is more notable than commonsense method, and speed is fast, efficiency high, low cost.At present, swash
Optical surface reinforcement technique has obtained relatively broad application in industries such as Ferrous Metallurgy, automobile, machineries.
At present, CO2Laser and YAG laser have obtained different degrees of application in every profession and trade, have embodied laser
The unrivaled advantage that technology has in the field such as processing and manufacturing and material surface treatment.But CO2Laser and YAG laser
The deficiency that device exists in itself also seriously limits its application in high-precision field, cannot also meet modern manufacturing industry and height is collected
Into, increasingly automated, efficient requirement.Optical-fiber laser as third generation laser technology representative, with other lasers without
Analogous technological merit, certainly will will substitute global major part high power CO2Laser and most YAG lasers.
The content of the invention
The technical problems to be solved by the invention are directed to the deficiency of prior art presence, there is provided one kind utilizes optical-fiber laser
The method for strengthening repairing mine mechanical surface.
In order to achieve the above object, the present invention uses following technical scheme.
A kind of method that utilization optical-fiber laser strengthens repairing mine mechanical surface, is in the waste and old hydraulic support column in colliery
Surface using optical fiber laser transmitting laser beam, fusing laser melting coating alloy powder carried out forming laser cladding layer
Surface reconditioning, specifically includes following steps：
(1) optical-fiber laser multifunction flexible system of processing working terminal builds
Using system integration technology, with reference to robot flexiblesystem, software communication coordinate system, safety shading guard rail,
Quality detection apparatus and optical fiber laser, set up laser multichannel export structure, set multioperation operating point, and structure is a set of can
Realize the security system work station of laser melting coating, laser roughening, Laser Surface Treatment, laser welding and laser cutting multiple function
Point, the software communication coordinates system and utilizes corresponding programming software, according to material surface performance, selectes surface treatment functional station
And technological parameter is formulated, realize conversion application of the laser between difference in functionality；It is multiple using dense wave division multipurpose and light time-division
Strengthen multi-wavelength optical-fiber laser with technology to export, so that modulation optical fiber laser output waveform, realizes the dense wavelength division of optical-fiber laser
Multiplexing and Optical Time Division Multiplexing transmission；The optical fiber laser power is 10kW, and its working optical fibre has 2000 μm, 1800 μm, 1500 μ
M, 1200 μm, 1000 μm, 800 μm, 600 μm, 400 μm of each 1 of core diameters, 20 meters of each length；
(2) optical-fiber laser cladding is prepared with alloy powder
Raw material neodymium 1-2%, vanadium 0.05-0.15%, chromium 5-8%, nickel 3-6%, molybdenum 0.1- are first chosen by weight percentage
0.2%th, silicon 0.1-0.3%, titanium 0.1-0.2%, aluminium 0.1-0.3%, carbon 0.1-0.2% and balance iron, are mixed to get iron-based conjunction
Bronze end；Then the poly- methyl hydrogen silicon for accounting for that iron(-)base powder total weight percent is 0.3-0.5% is chosen by weight percentage
The stearic acid of oxygen alkane, 0.5-1%；The polymethyl hydrogen siloxane and stearic acid of selection are added in appropriate absolute ethyl alcohol again, then
Stirring and dissolving, obtains organic liquid；Then by iron(-)base powder addition organic liquid, stirring obtains mixed slurry, heats
