Description
The present invention relates to a kind of continuous coated welding bar that is specifically designed to welds, particularly can realize the plane reciprocating continuous welding torch that high-current plasma arc welding connects.
All relate to the heavy current continuous transmission gun that aims at the supporting design of continuous coated welding bar in number of patent application is two patent application documents of 93 1 12594.4 and 94 2 26460.6, its purpose all is to be to realize the continuous wire feed of welding rod and transmission of electricity continuously.Both all adopt the chain type space circulation kind of drive, are driven chain and then driven by sprocket wheel to be installed on many on the chain electrode at a distance of pitch position between the welding rod electric contact is pinched welding rod and carries out continuous welding in the upset of chain transmission space, circulation.Different is that the former adopts the Dual chain belt moving electrode to send in the horizontal space upset, and the latter is strand, sends in the vertical space upset.
Because the electrode in the chain type welding gun carries out 360 ° shuttling movement with chain in the space, inevitable zone, front and back at two sprocket wheels forms one for being installed in the upset space of the electrode assembly on the chain.And the existence in this space, the conductiving point that certainly will increase welding gun electrode is to the distance between the arc region, thereby reduced welding current significantly.Welding rod with present diameter of phi 2.0mm, electric contact pitch 38.1mm is an example, adopts the welding of chain type welding gun, and electrodes conduct is put to the minimum average B configuration distance in arc district and reached 10cm, and the maximum weld electric current can't be broken through 200A, and this is the defective of a serious welding characteristic aspect.
On the mechanical electric structure of welding gun, also have following three shortcomings in addition:
1, along with the prolongation of welding gun useful life, driving-chain is loose because of wearing and tearing, causes the accumulation gradually of pitch error between conductiving point, has had a strong impact on welding quality;
2, the chain type welding gun must occupy two upset spaces between the sprocket wheel, has increased the volume and weight of welding gun;
3, the space of 360 ° of chain type welding guns upset has limited conductive cross-sectional area between busbar and the electrode, often makes the electrode temperature of welding gun too high.
The problems referred to above at existing chain type welding gun existence, the invention provides a kind of novel plane reciprocating continuous welding torch, use this welding gun, can overcome all drawbacks of chain type welding gun, thereby can carry out the common electrical arc-welding of continuous coated welding bar, can realize high-current plasma arc welding again.
The present invention is achieved in that
This welding gun of flatness and reciprocator comprises casing, movement, power input line, electronic-controlled installation and control cable, it is characterized in that described welding gun movement by a buncher and gear thereof, one form wire feeder assembly, a welding rod automatic clamping device and a plurality of electric conductor that a plurality of electric conductor flatness and reciprocator pinch welding rod and form, comprise the electric conductor tracks in addition.
This tracks is divided two sections: wire feed track and return the track that resets promptly advances.
The wire feeder assembly is realized the planar reciprocating of a plurality of electric conductors on tracks, comprise that a continuous wire feeder of electric conductor sends welding rod on the wire feed track that advances, electric conductor intermittently response agency withdraws from the wire feed track that advances at electric conductor, enters and it is resetted after returning the track that resets, and one moves into the track that resets, another electric conductor move into the wire feed track from the track quick plane that resets swing mechanism at intermittence with an electric conductor from wire feed track quick plane simultaneously.Time intermittently is the time of a pitch of advancing just.
Be distributed in a plurality of electric conductors on the track and be mutually independently pitch electric conductor, its length is pitch between the welding rod electric contact; It is made up of upper and lower seat, and conductive contact of each embedding is convenient to clamp welding rod and transmission of electricity; Following bottom of pitch electric conductor is a tooth bar, and the wire feed track that advances is provided with the wire feed gear, and both intermesh.
During welding, the pitch electric conductor meshes in turn by the wire feed gear in its following bottom tooth bar and the wire feed track under the effect of continuous wire feeder, and the last pitch electric conductor that successively incremeantal launching method is adjacent in track advances; The pitch electric conductor of this moment is in locking state under the effect of welding rod automatic clamping device, guarantee that electric conductor can clamp welding rod and send to and transmit electricity in self continuous motion.When the pitch electric conductor moves to the welding gun head on the wire feed track, break away from locking, unclamp welding rod automatically, and then under the effect of swing mechanism at intermittence, the pitch electric conductor is moved to the track that resets by the wire feed track by quick plane; Synchronization is delivered to pitch electric conductor that the welding gun afterbody waits for also under the snap action of swing mechanism at this by the response agency at intermittence on the track that resets at intermittence, moves to the wire feed track by the track quick plane that resets, and with the wire feed gears engaged.In the whole circulation motion process, the front and back position direction of pitch electric conductor does not change all the time, as 360 ° upset, has not so just realized electric conductor flatness and reciprocator continuous motion on tracks.
The invention has the advantages that:
1. adopt plane reciprocating continuous welding torch, need not to consider electrode upset space, conductiving point to the average distance in arc district is reduced to conductive contact on the pitch electric conductor, and (P is a pitch between the welding gun conductiving point to the minimum distance+P/2 in arc district, it is pitch between the welding rod electric contact, for purposes of the invention, pitch electric conductor length just), because this modular construction is simple, conductive contact can be designed to almost near the welding gun front end shell.Welding rod with diameter of phi 2.0mm, pitch 38.1mm is an example, adopts the welding of this welding gun, has only 4cm to the average distance in arc district, only is 2/5 of chain type welding gun.
2. since conductiving point to the arc offset from shortening, welding current rises significantly.Still the continuous welding rod with Φ 2mm, pitch 38.1mm is an example, uses this welding gun, and welding current can reach 270A~300A, can once penetrate the thick steel plate of 16mm, has realized the plasma arc welding (PAW) under the big electric current.
3. because sending to of pitch electric conductor is tooth bar and the motion of wire feed gears engaged that shapes by its bottom, so pitch is influenced by the electric conductor machining accuracy only between conductiving point, in use be not subject to the interference of extraneous factor, loss is low, keep the good precision of sending to, no accumulated error.
4. lean on mutual jacking campaign between each pitch electric conductor, its both sides and bottom rack flange all can become the transmission of electricity contact plane, and the sectional area of therefore transmitting electricity is very big, and corresponding area of dissipation also increases.
5. conductive contact and pitch electric conductor up and down seat fixedly connected, changed chain type welding gun conductive contact movable state in electrode tip holder, reduce contact resistance, improve welding gun heating situation.
