Abstract
Flexible welding gun for congumable electrode is used for arc welding, particularly the welding gun in the melting pole semi-automatic welding.The adapter part that connects nozzle and handle in the welding gun is made up of many segment sleeve pipes (1).The tube ends left and right sides is the circular arc of marginal belt small stair, and both sides are for slidably inlaying shape up and down.Seizing wire passes sleeve pipe inner arc center latch (6) hole, and sleeve pipe is bound up, and the fixing shape of taking over guarantees good contact conduction.Sleeve-barrel roollr (2) is arranged in the sleeve pipe, and the guiding welding wire advances.The characteristics of this flexible pipe are: operating angle is variable, and wire-feeder resistance is little, process stabilization.
Description
Flexible welding gun for congumable electrode is used for arc welding, particularly the welding gun in the melting pole semi-automatic welding.Welding gun is a vitals in the melting pole semi-automatic welding.It determines on the one hand to a great extent whether the semiautomatic welding operation is flexible, or difficultly awkward, even can not use at all, also affects the stability of wire feed process on the other hand, affects welding quality.
For the joint of different spatial different types, wish that all electrode keeps the relative angle of some the bests in welding process.In the coated electrode manual electric arc welding, accomplish what difficulty this point does not have, the clamping angle of welding rod in electrode holder is just passable as long as change.And in the melting pole semi-automatic welding of continuous wire feed, welding gun generally is unyielding, this hand that just have to require the welder to hold welding gun is deacclimatized this requirement, in welding process, remain a certain relative posture, and this posture often is not that nature is comfortable, and the time is a length slightly, and it is tired that the workman will feel, fail to promote more widely so this also is a semiautomatic welding, replace one of reason of manual electric arc welding.
Patent (1) is the flexible welding gun of argon tungsten-arc welding.This commodity are promoted at present existing advertisement.But, also there is not similar data to consumable electrode.
In the various forms of melting pole guns, gooseneck type is because lightly simply use the most extensively.But welding wire can be subjected to certain resistance by the gooseneck corner.It is provable that welding wire is carried out theory analysis by the suffered resistance of bend pipe: when bend pipe one end has resistance F
0The time, must apply directed force F at the other end, and F
1=Fe
μ θμ is the coefficient of friction of bend pipe herein, and θ is an angle of bend.Because μ is forever greater than zero, F is inevitable greater than F
0That is to say that must apply bigger active force at bend pipe one end just can overcome a certain resistance of the other end.Far away more from wire-feed motor, θ is big more, and is also just big more for overcoming the required power that applies of certain resistance, also just big more to the influence of wire feed and arc burning stability.The gooseneck corner of welding gun just in time is place so in the semiautomatic welding system.This point is particularly evident when using thicker welding wire.
Patent (2) has proposed a kind of wire convey soft pipe that sleeve-barrel roollr is housed.Be rolling friction owing to become sliding friction, wire-feeder resistance significantly reduces.Mentioned a kind of flexible pipe of transverse curvature variable rigidity in the document (3).Flexible pipe is built up by the nahlock series connection of many band centre bores, and welding wire is sent in the heart hole hereinto.Be with aperture outside around the nahlock, steel wire penetrating is arranged in the aperture.Nahlock can freely relatively rotate in certain limit, makes the flexible pipe transverse curvature.But after certain limit, limited by rope capacity, can not be further crooked again.Can avoid forming the too small dead folding of radius of curvature like this, produce excessive local resistance.
But on melting pole gun, all adopt the helix tube of spring steel wire coiled to guide welding wire, also do not see and be the trial that replaces sliding friction with rolling friction.
Purpose of the present invention is the melting pole semi-automatic welding welding gun of little, the variable-angle of a kind of wire-feeder resistance of development, reliable operation.The essence of this welding gun is the wire convey soft pipe that has improved to be extended in the welding gun go.
Fig. 1 is each part of welding gun.(1) be nozzle, welding wire (2) stretches out from nozzle, and (3) are handle, and for connecting the adapter of handle and nozzle, (5) are the wire convey soft pipe that drags behind the welding gun (4).The above-mentioned composition of this welding gun is identical with general gooseneck type welding gun commonly used.Different is that adapter (4) part is flexible, and it is fixing securely taking over shape to take out the seizing wire that is right after in the pipe by eccentric wheel (6).
Fig. 2 has shown the structure of this adapter.(1) is sleeve pipe among the figure, is made of copper, and plays the effect of conduction welding current simultaneously.Sleeve-barrel roollr (2) is arranged in the sleeve pipe.Two pairs of rollers are arranged in every joint sleeve pipe shown on the figure.The roller periphery is fluted, and welding wire (3) promptly advances along this groove.The axle of all rollers (4) all is parallel to each other.The Roller Shaft diaxon also is with spile (5).The length of spile is slightly larger than casing wall thickness, therefore with the roller both sides of tapering not can with the casing wall direct friction, only contact with spile near axis, do like this and can reduce the suffered moment of friction of roller, and avoid the wearing and tearing of casing wall, spile and axle are all lived with the casing wall weldering, to play the bracing reinforcement effect.The tube ends left and right sides is a circular arc.There is small stair the circular arc both sides.Adjacent two sleeve pipe circular arcs one protruding are recessed, can relatively rotate, and keep good contact.Sleeve pipe both sides up and down becomes slidably to inlay shape.Sleeve pipe can relatively rotate in certain limit like this, but after reaching this limit, owing to be subjected to the restriction of circular arc step small in ends, and can not be further crooked, in order to avoid form local dead folding.Sleeve pipe can not move mutually perpendicular to flexible in-plane, to guarantee the stability of the formed welding gun integral body of sleeve pipe.There is latch (6) at sleeve pipe left and right sides center of arc place, lives with Socket welding.Seizing wire (7) passes pin hole along the sleeve pipe two side sleeve pipe is associated in together.Because latch is in center of arc, therefore when sleeve pipe relatively rotates, the latch invariant positionization, steel wire rope all the time with the sleeve pipe central lines.Distance is constant between latch, and rope capacity is constant, and wherein tension force is also constant.Steel wire rope one end is fixed, and the other end can be regulated and take over into needed shape after taking out tightly slightly by the eccentric wheel among Fig. 1 (6).Further take out tight steel wire rope this shape is fixed securely, in whole welding process, remain unchanged, and keep well contact between sleeve pipe, guarantee passing through of welding current.
Whole adapter overcoat sebific duct (not expression on the figure) is to guarantee air guide and electric insulation.Nearer because of distance electric arc, sebific duct should be able to be heat-resisting.
This welding gun characteristics are that operating angle is variable, and wire-feeder resistance is little, process stabilization.
Weld the joint of various diverse location different types with automatic weldering, be difficult to the place, in-position at some especially, also can utilize the extension of the present invention, make the wire feed conduction of consumable electrode or the usefulness that fills silk, handpiece structure is simplified as head.
