Description
Technical field
The present invention relates to welding technology field more particularly to a kind of dedicated welding robots of airconium alloy plates.
Background technology
Zirconium is a kind of corrosion resistant metal, belongs to rare non-ferrous metal material, and zirconium and zircaloy have excellent corrosion resistance, it is right
Most of organic acids, inorganic acid, highly basic and some fused salts have extraordinary corrosion resistance；And with preferable heat resistance, processing
Property, there is application in industries such as oil, chemical industry, nuclear energy.But zirconium metal welding when to welding procedure and welding condition requirement compared with
Height, Seam and heat effected zone is easily by the element pollutions such as oxygen, hydrogen, the nitrogen in air, the hard and crisp compound of generation, and generate brittleness
Acicular structure, improve the hardness of welding point, intensity, but plasticity declines, corrosion resistance also declines to a great extent.
The welding of traditional airconium alloy plates uses manual argon arc welding bottoming, and manual electric arc welding capping, this method is due to by people
Member, the influence of equipment, material, environment, weld seam be also easy to produce crackle, stomata, slag inclusion, incomplete fusion, it is lack of penetration the defects of, heat input
It is excessive, heat affected area increase；And this welding method efficiency is low, and operator's labor intensity is big, and there is also ginsengs in product quality
The shortcomings that difference is uneven, stability is poor.
Worker can be made to be freed from the manual labor of big intensity using welding robot welding, manpower be saved, during welding
The welding parameter of every weld seam can all be set, reduce welding quality is influenced by human factor, is reduced to worker
The requirement of operating technology improves welding quality and quality stability, although welding robot welding field have it is above-mentioned excellent
Gesture, but currently without a kind of welding robot dedicated for airconium alloy plates welding.
The present invention provides a kind of dedicated welding robot of airconium alloy plates, easy to operate, at low cost, not by environmental restrictions,
The degree of automation is higher, zirconium material is protected to prevent from polluting in entire technical process, and welding point has higher intensity and simultaneously
With excellent plasticity and toughness.
Invention content
In order to solve the above technical problem, the present invention provides a kind of dedicated welding robots of airconium alloy plates.
The present invention is realized with following technical solution：
A kind of dedicated welding robot of airconium alloy plates, the welding robot include welding gun, rack, linear module, servo electricity
Machine, wire reel, welding wire, wire feeder, argon tanks, appendix, control cabinet and special fixture.
Further, the servo motor is arranged on the end of the linear module, for driving the linear module, institute
Linear module is stated on the crossbeam of the rack；The argon tanks, control cabinet are arranged on the platform of the rack；It is described
Argon tanks are connected to by the appendix on the welding gun；The welding gun, wire reel, welding wire, wire feeder composition one are whole
Body is mounted on the slide unit of the linear module, realizes the horizontal rectilinear motion of welding gun；The special fixture is arranged on described
The underface of welding gun positions airconium alloy plates to be welded for fastening.
Further, the special fixture includes chassis, support column, L-type fixture, fastening bolt；The chassis is located at
On ground, the support column is arranged on chassis upper surface, is used to support airconium alloy plates, and the L-type fixture is arranged on the chassis
Both sides, and be provided with threaded hole, the fastening bolt and the corresponding threaded holes of the L-type fixture close, and compress the upper of airconium alloy plates
Surface, for fastening airconium alloy plates.
Further, the welding robot further includes a kind of combined type welding gun protective cover, and wherein welding gun protective cover is set
In the lower end of welding gun, the welding gun protective cover has the bending edges of opening upwards in the left and right sides；Two pieces of airconium alloy plates upper surfaces
Left protective cover and right protective cover are set respectively, and the left protective cover and right protective cover are fastened by bolts in rear and front end special
It on fixture, prevents from moving or coming off in welding process, the left protective cover and right protective cover are respectively provided with the bending edges that Open Side Down；
Left protective cover and right protective cover overlap respectively with welding gun protective cover.
Further, the process for using of the welding robot includes the following steps：
Step 1 needs the airconium alloy plates welded to be machined, and clear up airconium alloy plates discharge surface to two pieces, goes
Removing rust, grease and dust；
Two pieces of airconium alloy plates are fixed on special fixture by step 2, it is ensured that the relative position of two pieces of airconium alloy plates and its gap,
U-shaped groove is formed, while ensures the position relationship of weld seam and the welding gun；
Step 3, the welding gun slide, on U-shaped slope under the driving of the servo motor with the slide unit level of the linear module
Reciprocal welding in mouth welding bead, and do not stopped in the middle part of each welding bead.
Further, the argon tanks use the argon gas that quality purity is 99.99% to be used as protection gas, and range of flow is
10L/min-15L/min。
Further, the welding wire uses flux-cored wire, and the gage of wire is 1.2mm-2.0mm, and welding current is
80A-140A, weldingvoltage 15-25V, 10~20cm/min of speed of welding are not preheated before weldering, each welding bead interlayer temperature control
Below 100 DEG C.
Further, the width range for the U-shaped groove that two pieces of airconium alloy plates are formed is 5-15mm, two pieces of airconium alloy plates
Gap size be 1-3mm；During welding, welding bead is successively superimposed, and bottom is backing run, and middle part is filler pass, and top is lid
