Abstract
A kind of laser-arc weldering composite cladding of the present invention remanufactures the device of railway train wheel, propose the apparatus structure combined with swing arc weldering using broad band laser, arc welding makes cladding weld width consistent with laser bandwidth by yaw, protect to form inertia protection gas-bearing formation by argon gas, accelerate the speed of wire melting under laser action and weldering is deepened deeply, laser beam forms stirring to molten bath makes gas discharge and slag making abundant, avoid cladding defect and be mingled with generation, cladding layer forms stronger metallurgical binding with matrix simultaneously, effectively solve electric arc welding heat affected zone big, combination interface base material mechanical properties decrease, weld layer there is a problem of gas hole defect and to be mingled with many and laser melting coating efficiency low, realize the combination of double thermal source advantages, effectively reduce railway train wheel and remanufacture cost.
Description
Technical field
A kind of laser-arc weldering composite cladding of the present invention remanufactures the device of railway train wheel, using broad band laser and pendulum
Dynamic arc welding is combined, and effectively solves electric arc welding heat affected zone greatly, and combination interface base material mechanical properties decrease, weld layer is deposited
In gas hole defect and it is mingled with many and low problem of laser melting coating efficiency, realizes pair combination of thermal source advantages, effectively reduces iron
Road train wheel remanufactures cost.
Background technology
Railway train wheel mainly includes lorry, car and high ferro wheel, and the material of general rail is CL70 steel, wheel
Material be CL60 steel, the life-span that wheel would rather be sacrificed from the principle of design does not sacrifice life-span of rail, main cause yet
It is to change rail to influence train operation, upsets the running order and safety guarantee of whole railway, freight car wheel completes to transport
Can lower maintenance and replacing online after task.So the requirement to railway train wheel is can not be more more resistant than rail.In China
The wheel value of the annual offline replacing due to abrasion reaches 1,000,000,000 yuan or so, and the wheel changed is taken and melts down melting again
Use, so waste mass energy and unnecessary labour payment.As railway speed increase and a large amount of of high ferro are come into operation, wheel
Abrasion and change problem and more protrude, this has become the very big cost of railway operation, wheel to remanufacture demand urgent.
Conventional railway interests also took welding technology and repaired to the wheel scrapped, but due to quality it is difficult to ensure that,
High to operator's skill set requirements, along with batch is big, therefore the department for participating in is more, causes quality to ensure, so very big prestige
Safety of railway traffic and personal security are coerced, state-owned railroads office is forced to stopped the production of arc welding multiple wear wheel.High ferro
A large amount of operations, wheel remanufactures problem and is brought into schedule again.
Domestic other business research are crossed and use laser melting coating means multiple wear wheel, and by proving and analyzing, performance and index are all
The requirement of railway wheel technical conditions is reached, but they have met with practical application difficulty, railway train wheel new product price and car
Two-layer constraint of the wheel wearability no more than the wearability of rail.Laser melting coating remanufactures wheel cannot meet the limit of manufacturing cost
System, the price that laser melting coating remanufactures railroad train wheel cannot be received using department.
We develop that wheel that the weldering of broad band laser and swing arc combines is compound to remanufacture device, effectively solve sharp
The too high shortcoming that cannot ensure with arc-welding quality of light manufacturing cost.For railway train wheel high-quality, high efficiency, low cost are made again
Make there is provided possible.We propose the concept of special for automatic equipment simultaneously, further increase labor productivity, it is ensured that plus
Work process stabilization and complicated procedures of forming reduce further and added by production process thinking of the Function Decomposition by simple machining cell
Work cost improves quality stability.
The content of the invention
High efficiency, high-quality, low cost are three basic demands that railway train wheel is remanufactured, and me is required around this
Develop the composite cladding device that broad band laser combined with arc welding railway train wheel remanufactured, while developing
Special for automatic equipment is decomposed complicated processing process and forms productivity.
If Fig. 1 is the apparatus structure signal that laser-arc weldering composite cladding remanufactures railway train wheel, electric arc 11 passes through
Yaw 12 makes cladding weld width and the bandwidth of laser 13 about 13*1.5（mm）Unanimously, protected by argon gas 14 and form inertia protection gas
Layer, the burn-off rate of welding wire is accelerated under the effect of laser 13 and weldering is deepened deeply, and laser beam forms stirring to molten bath 15 makes gas
Hole is discharged and slag making is abundant, it is to avoid cladding defect and be mingled with generations, while cladding layer and matrix 10 form stronger metallurgical junction
Close.
The manufacture of railway train wheel performs TB/T449-2003《Locomotive car wheel flange tread profile》、TB/T2817-
1997《Rail truck rolling steel monolithic wheel technical conditions》, railway train wheel remanufacture must be fulfilled for standard specification will
Ask.
As Fig. 2 show railway train car wheel structure, due to high-speed cruising, load is big, therefore abrasion is very big, car for wheel
Wheel key wear hub surface 1 and wheel rim medial surface 2, the compound device that remanufactures of laser-arc weldering is mainly in hub surface and wheel rim
Processing is implemented in inner side, and wheel hub is general unilateral to need the cladding 6-10mm, wheel rim to need cladding 5mm or so.
The process of the device that laser-arc weldering composite cladding as shown in Figure 3 remanufactures railway train wheel is illustrated, weldering
Silk 6 by wire feeder be pushed to arc-welding it is first 5 output, due to welding wire 6 be arc-welding an electrode its produce electricity with rim faces 2
Arc discharge, wire melting, laser beam focal is acted in weldering beam molten bath 9, metal in layer molten bath is sufficiently stirred for, there is provided energy
Amount lifts welding wire feeding speed, and slag making and stomata are reduced, and heat affected area reduces, and improve effective energy utilization rate.Wig-wag 7 makes
Arc welding width is consistent with laser bandwidth degree, laser energy is fully used, and improves fuse amount.
