Description

Vertical arc welding device

The present invention relates to vertical arc welding device.

Traditional upright automatically to welding, as electrogas arc welding, electroslag welding, and gas shield welding torch weave bead welding connect, be mainly used in the steel wall welding of shipbuilding, cylindrical shape oil tank and steelframe, bridge, heavy electromechanical equipment, ironmaking equipment etc.

Though the former efficient height when weld high strength steel, because that heat is advanced in welding is big, can cause the notch toughness deterioration of weld metal and mother metal heat affected zone etc.And the latter is a target owing to the quality with the raising weld part, will sacrifice welding efficiency sometimes, owing to be to carry out the multilayer welding, the weld defect incidence of each interlayer is higher simultaneously.And use the Large Storage Tanks oil tank of high strength steel building in succession recently, under these circumstances, in order to guarantee the quality of heat affected zone, strong request is adopted and is hanged down into thermal weld, at this requirement, use thin diameter tube shape welding wire and make electrogas arc welding that electric arc point moves by vibration at high speed because can carry out the actively little groove welding of blocking of groove section expeditiously and be applicable to standing of steel wall to hang down into heat to welding at the thickness direction of plate.

Below briefly explain the device that carries out this electrogas arc welding, stand vertically and adjacent 2 block plates between groove (extending) inboard at vertical direction z, across glass tape the copper block of natural air cooling or water-cooled is fixed, then place the slip copper block of water-cooled in the table side, gone into to weld the flattened flex tip (tip member of welding torch) of usefulness by the spatial interpolation of groove of this slip copper block (relative) and groove encirclement with groove, make it make vibration at high speed at plate thickness direction x on one side and supply with thin footpath welding wire by crooked tip continuously to this space on one side, and on one side continuously to crooked tip (welding torch) and (z) driving upward of slip copper block, Yi Bian carry out the upright of groove to welding.

Welding torch, welding torch vibrating mechanism and slip copper block are loaded on the welding chassis, Yi Bian this chassis can automatically carry out speed control along with the carrying out of welding, are promptly switching at a high speed and between low speed, Yi Bian rise.Protective gas uses carbon dioxide, sends into the groove space from the nozzle of being located at slip copper block top, and welding torch vibrates at the thickness direction x of steel plate with 50-200 time/minute frequency.Like this, not only can carry out the zero defect welding to blocking groove, simultaneously, can obtain the welding bead outward appearance (Japanese patent of invention bulletin 1988-66634 communique, Japanese patent of invention are announced the 1989-22067 communique) of the very careful beauty of waveform because vibration at high speed combines with supplying with the two effect of thin footpath welding wire continuously.

But, in aforesaid electrogas arc welding, the groove shape be according to the plate thickness of the mother metal (steel plate) that will weld the asynchronous plate thickness of mother metal plate thickness is poor or welding after the purposes of finished product and fixed.In order to improve the intensity of seam (the former groove part after the welding), preferably according to the groove shape adjustment welding wire of 2 mother metals for groove and the copper block slot part relative with it enter angle (welding wire is at the residing homing position of pool of molten metal of space formation in the groove), and make the welding quality of seam cross section (x, y plane) each several part even.In the disclosed vertical arc welding method, the operator will carry out welding torch being fixed after the angular adjustment (regulating with the y axle is the angle of rotation at center) at plate thickness direction x with manual methods earlier before the welding beginning in the open 1979-148155 communique of Japan Patent.That is, preestablish the angle that enters of welding wire.Thus can according to the groove shape of groove shape and the slip copper block relative with it regulate welding wire plate thickness direction x enter angle (with the intersecting angle of z axle), and can determine that welding wire is to by the homing position of the pool of molten metal that forms in the space that groove surrounded of groove and copper block.So, just can dwindle the heat affected zone of mother metal, and the fusion penetration of groove each several part is fixed, can obtain evenly beautiful welding bead.

Yet disclosed method remains in following problem in the above-mentioned 1979-148155 communique, promptly can not change the enter angle of welding wire at mother metal width y (with the direction of plate thickness direction x and groove bearing of trend z quadrature).For example in the different occasion of mother metal plate thickness, if the fusion penetration unanimity that the welding torch heat affecting is caused in the different seam portion of plate thickness then can make plate thickness be lower than the weld part of the thicker mother metal of plate thickness than the weld part intensity of thin mother metal.Such seam portion is in the joint balance that can not obtain aspect the durability between 2 block plates, and mother metal one side that can the slave plate thinner thickness begins deterioration, and the result causes the durability decline of whole seam portion.As the intensity that will make seam be not subjected to the influence of plate thickness difference and accomplish whole evenly, then must make near the thin mother metal groove of plate thickness heat affected zone less than near the thicker mother metal groove of plate thickness, and reduce fusion penetration.

In addition, even in the variform occasion of groove, the big side in groove angle of inclination also needs more built-up welding, and the welding wire that will change the welding torch angle that comprises mother metal width y enters angle, also will increase groove angle of inclination big mother metal one side's heat affected zone.

On the other hand, there is other occasion of difference of height on the plane that forms 2 block plates of groove on the face of facing at welding torch, when the z direction of extending at groove when the steel plate face is uneven, be that near the groove steel plate face is when y direction or z direction not exclusively are the plane, slip copper block can be partly from steel plate face come-up in the face of the face of steel plate, and the motlten metal in the pool of molten metal when the worst in the space that the groove with groove and sliding block forms can drain to the block outside.Though generally this leakage can not take place, have nothing in common with each other at groove cross section each several part for the welding fusion penetration of mother metal, thereby destroyed the uniformity of welding quality.As previously mentioned, when there is the thickness of slab difference in mother metal, or the groove shape is when being asymmetric state for the z axle, preferably the homing position of welding wire for pool of molten metal staggered to the y direction according to degree of asymmetry, distribute with the heat that advances of regulating groove cross section each several part, yet when the parallel mobile adjusting of the y direction of making welding torch, crooked sometimes tip can be blocked in slip copper block place, thereby welding wire can not be determined in required homing position (posture).

In view of the foregoing, the 1st purpose of the present invention is to provide a kind of groove cross section each several part of can regulating more neatly to weld the into vertical arc welding device of heat, the 2nd purpose is to provide a kind of vertical arc welding device that makes slip copper block carry out reliable profiling driving fit to the welding object steel plate, and the 3rd purpose is to provide the vertical arc welding device of giving homing position of a kind of metering needle more neatly to the welding wire in groove and slip copper block space that groove surrounds.

To achieve these goals, the present invention by the following technical solutions, for the ease of understanding, in bracket, charged to drawings and Examples described later in the major part corresponding symbol.

(1) the present invention is a kind of vertical arc welding device, possesses track segment (127); This track segment (127) is fixed in steel plate (wL, wR) guide rail fixer on plane (120a) that stands vertically in fact and have the groove (α) that extends in vertical direction (z); Be loaded on track segment (127) and along track segment its bearing of trend (z) voluntarily, possess walking and drive chassis (100) with electro-motor (MD); Vertical position welding welding torch (T); Make this welding torch facing to described groove and the welding torch supporting mechanism that supported, supported simultaneously with prescribed form by described chassis (A, C-F); Copper block (P); The block supporting mechanism (G) that makes this block face toward described groove and be supported, supported by described chassis simultaneously with prescribed form; This block supporting mechanism can make described copper block around with Z direction quadrature and rotate freely with the parallel plane axis (g12a) of described steel plate in fact, and to the direction pressurization near described steel plate,

Its characteristics are, described block supporting mechanism (G) can also make the described copper block (P) of support rotate freely around the axis (g9) parallel with groove bearing of trend z, and make it can be free to advance or retreat with the x direction of above-mentioned axis (g9) quadrature.

So, since copper block (P) can the z axle and these 2 on y axle be that freely rotate at the center, so when there is the height difference on the plane of 2 block plates that form groove, or the steel plate face is when the z direction of groove extension is uneven, copper block (P) all can take to imitate the posture of steel plate face.Again since block supporting mechanism (G) near the direction of the steel plate of x direction to copper block (P) pressurization, so just posture and the driving fit of steel plate face of copper block (P) to imitate the steel plate face.Thereby copper block (P) can not float from the steel plate face, groove cross section each several part to advance heat more even, can improve welding quality.

See Fig. 2, on chassis 100, adorning the x direction driving mechanism B of copper block.X direction driving mechanism B is identical with the y direction adjustment organization A of welding torch T, supports splined shaft b3 and determines its y position.On splined shaft b3, fixing columnar support component b4, also supporting the hold-down mechanism G of copper block with support component b4 through support component b5.

9. the hold-down mechanism G of copper block

The hold-down mechanism G of copper block is supported in the support component b5 of copper block x direction driving mechanism B.Fig. 6 is the longitudinal section of the hold-down mechanism G that sees in the arrow 6A of Fig. 2 direction, and Fig. 7 represents the 6B-6B line section along Fig. 6.Inserted wheel hub g5 among the sleeve g1 with support component b5 support, and be fixed as one with sleeve g1.In wheel hub g5 splined hole is arranged, inserted the support arm g4 that outer peripheral face is cut spline in this hole, this support arm g4 can move freely in the y direction relative to wheel hub g5, but can not rotate.What screwed in sleeve g1 that band handles knob g3 stretches out regulating sleeve g2.With the compression helical spring g6 that stretches out regulating sleeve g2 support support arm g4 is pushed to the direction that makes sleeve g2 near groove.Screwed in the threaded rod g4a that connects sleeve g2 and compression helical spring g6 in support arm g4, the head of this threaded rod g4a can prevent that support arm g4 from coming off from sleeve g1.

At the tip of support arm g4, being equipped with the pin g9 that extends in the z direction is that back-up block g11 is freely rotated at the center.Back-up block g11 is that the center rotation is keeping copper block P freely with the pin g12a that extends in the y direction.Thereby copper block P can rotate relative to support arm g4 for the center with the y axle by the z axle.With the z axle is that the rotation at center can make copper block P simultaneously and 2 block plate wL, WR driving fit, and is that the rotation at center can make copper block P that the x direction of 2 block plate wL, wR is tilted or the profiling driving fit is done in bending with the y axle.

When the g3 clockwise direction of handling knob was rotated, regulating sleeve g2 entered the inside of sleeve g1, and by compression helical spring g6 support arm g4 is pushed away to left, makes copper block P and 2 block plate wL, WR driving fit therefrom.And in a single day further turn clockwise handling knob, then copper block P is pushed into the just reinforcement of thrust of 2 block plate WL, WR.And when the g3 inhour of handling knob was rotated, this thrust just weakened, if further do the inhour rotation, copper block P just breaks away from from 2 block plate WL, WR.When the place ahead did not have steel plate WL, WR, the g3 clockwise direction rotated to the screw-in limit of the relative sleeve g1 of regulating sleeve g2 even handle is handled knob, and the head g4b of threaded rod g4a can not extract from regulating sleeve g2 yet, so support arm g4 can not come off from wheel hub g5.In addition, length about threaded rod g4a, in the present embodiment, be when the right side of the right side of head g4b and the g3 that handles knob is in same plane, the length when being 2kg through the support arm g4 of compression helical spring g6 and the thrust that copper block P is pushed into 2 block plate WL, WR.Regulate the g3 that handles knob by rotation, make the right side of the head g4b of its right side and threaded rod g4a be in same plane, can remain the thrust that copper block P is applied 2kg.

10. copper block P

At groove face (surface) the restricted cap bead shape relative of copper billet p1, that extend in the z direction with steel plate WL, WR.With surperficial opposing backside surface, 2 of linking to each other with cooling water channel p1a in the copper billet p1 (water filling with and draining usefulness) hose couplings are arranged, wherein 1 hose coupling jwa shows in Fig. 6.The opening p2a that on the groove that the formation welding bead on copper billet p1 surface is used, has protective gas supply pipe p2 to be communicated with.This air supply pipe p2 tilts to be fixed on the copper billet p1.In the side of air supply pipe p2, adorning hose coupling jg, supply with protective gas by this to air supply pipe p2.

In the embodiment of above explanation, copper block P is that rotate freely at the center with z axle and y axle, push copper block P to 2 block plate WL, WR because of its elastic force when compression helical spring g6 is flat, so as 2 block plate WL, when there is thickness difference in WR, even or when the z direction exists crooked or tilts, copper block P also can with 2 block plate WL, WR driving fit, and can not produce come-up.Thereby pool of molten metal is surrounded fully by copper block and groove, and it is even that heat is advanced in the welding of groove cross section each several part.

In addition, even not simultaneously at the plate thickness of vertical steel plate WL, WR, because available left and right sides angle adjusting mechanism F regulates the skew angle of rotation of welding torch T in left and right sides y direction, so and compare in the occasion of the parallel mobile adjusting welding torch T of y direction merely, wider from the welding wire that crooked tip x2 sends in the homing position adjustable range of y direction.That is it is higher that, the homing position of y direction is regulated flexibility.When the thickness of 2 block plates not simultaneously, can make the groove of the heat affected zone of thin vertical steel plate one side, and reduce fusion penetration less than thicker vertical steel plate one side.Like this, the joint strength that can suppress thin vertical steel plate unilaterally worsens, and makes joint strength not be subjected to the influence of thickness of slab difference and accomplishes evenly whole.In addition, even the variform occasion of groove the occasion of レ type groove (for example), also can regulate the welding torch deviation angle of the width y of vertical steel plate, vertical steel plate one side big at the groove angle of inclination increases heat affected zone (fusion penetration), and can increase built-up welding.The result can improve the durability of seam integral body.
