Description
Technical field
The present invention relates to a kind of wire feed system of welding equipment, relate in particular to a kind of other wire feed system for automatic plasma arc welding and argon tungsten-arc welding.
Background technology
At present, along with the development of solder technology, engineering welding quality has proposed requirement better, and traditional welding method can not adapt to modern project demand.Argon tungsten-arc welding and plasma arc welding method, because arc length keeps stable, easily obtain the stable weldquality of high-quality, and face of weld is attractive in appearance, level and smooth and evenly, can be applicable to vitals as in nuclear power, aerospace industry.In plate sheet welding, argon tungsten-arc welding and plasma arc welding (PAW), all without filler wire, still, in thick plates process, need filler wire.The wire feed system of argon tungsten-arc welding and plasma arc welding (PAW) and welding current, voltage etc., without direct relation, are called other wire feed system.In welding process, can, as MIG or CO2 welding because the droplet transfer causes that arc voltage and curent change produce and splashes, not cause surface weld surface not attractive in appearance.
In argon tungsten-arc welding and the other wire feed of plasma, inappropriate other wire feeding mode easily causes the mode with bridging transition that welding wire cannot be uniform and stable to be transitioned in metal bath.Other wire feed to welding wire enter molten bath angle, with respect to plan-position and the locus in molten bath, all have higher requirement, higher to operator's specification requirement.When mated not at that time with welding procedure wire feed angle and position, easily occur: wire feed front end touches still unfused mother metal, there is jackscrew phenomenon; Wire feed front end directly inserts in electric arc, and now welding wire is most advanced and sophisticated has a segment distance at electric arc on axially with metal bath, and the sectional quick-fried disconnected phenomenon of welding wire easily occurs, or goes in a section the molten bath of transition of welding wire.Above-mentioned two kinds of modes all can cause silk filling speed unstable, suddenly neglect soon slow wire feed and produce rugged weld reinforcement, and when serious, welding wire cannot be transitioned in metal bath and go.The stable molten bath that simultaneously different welding conditions produces varies in size, and required silk filling position just needs difference, and when arc length is different, required wire feed angle just needs difference.Therefore high-quality appearance of weld needs suitable wire feed angle and position.And common wire feed Jia Chi mechanism cannot meet position and the wire feed angle problem of the wire feed that regulates welding wire in the market simultaneously, to operator, many troubles have been brought.
Summary of the invention
For above-mentioned prior art, in order to overcome general wire feed Jia Chi mechanism, in welding process, easily occur that wire-feeder resistance is large, the welding wire of fusing cannot be transitioned into molten bath, the problem that wire feed angle and position cannot regulate in real time in welding process, the invention provides the other wire feed Jia Chi of a kind of welding mechanism, Ci Jiachi mechanism can be very easily in both direction adjusted wire feed position and rotation wire feed angle, especially in welding process, also can regulate at any time position and the angle of wire feed, without stop welding when wire feed is unstable, go to regulate wire feed position and angle, improve welding quality simultaneously to operator's part that brings a lot of convenience.
In order to solve the problems of the technologies described above, the other wire feed Jia Chi of a kind of welding of the present invention mechanism, comprises wire feeding guiding tube, welding gun cramping body, cross skid and wire feed angle adjustment mechanism; Described cross skid is connected with described welding gun cramping body, and described wire feed angle adjustment mechanism is connected with described cross skid with described wire feeding guiding tube respectively; Described cross skid consists of A one-way sliding mechanism and B one-way sliding mechanism, described A one-way sliding mechanism comprises base for supporting, roller screw, feed rod, rotary handle and slides table top, described A one-way sliding mechanism is identical with the structure of described B one-way sliding mechanism, the base for supporting in table top Shang，Liang Tao one-way sliding mechanism of sliding that the base for supporting of described B one-way sliding mechanism is fixed on A one-way sliding mechanism is and is arranged vertically; Described wire feed angle adjustment mechanism comprises bracing frame, the table top that slides in one end of support frame as described above and described B one-way sliding mechanism is fixed, the middle part of support frame as described above is through a screw rod, one end of described screw rod is provided with handle, on the other end of described screw rod, be set with a compression spring, between described screw rod, support frame as described above and described wire feeding guiding tube, be provided with a T font frame, the cross bar two ends of described T font frame are connected with the other end of support frame as described above and the other end of described screw rod respectively, and the montant end of described T font frame is connected with described wire feeding guiding tube.
Compared with prior art, the invention has the beneficial effects as follows:
As shown in Figure 1, in technical solution of the present invention, be that to take the tip of tungsten electrode 1 subpoint on weldment 2 be initial point, make X and Y-axis.Welding wire 13 has apart from dx and Y-axis and has apart from dy with respect to X-axis with the intersection point of weldment 2, there is a suitable wire feed angle [alpha] simultaneously, and good wire feed position will have rational dx, dy and α, weld other wire feed Jia Chi mechanism by the present invention and can regulate easily dx, dy distance and welding wire 13 with respect to the angle [alpha] of weldment 2.
Utilize the preparatory stage of the present invention before welding can be very easily adjusting wire feed position and wire feed angle on a large scale.Different welding conditions obtains different molten bath sizes, the wire feed position needing is different, the present invention can under the situation that does not need to stop welding, solve welding process in angle and position problem when incorrect, real-time adjusting wire feed angle and position, thus avoided in prior art due to degradation situation under the weldquality that constantly starting the arc receipts arc test silk filling position and angle cause.In addition, by changing the cramping body of different size and the ignition tip of different-diameter, the present invention is applicable to welding gun and the welding wire of any specification.
