In other words, the present invention is the division center body with above-mentioned rotation circle, assemble welding head and subsidiary machine thereof thereon after, constituted the outside automatic soldering device of pipe, inner automatic soldering device and inside and outside automatic soldering device.
Particularly, at the root of weld of pipe 2 rotation circles have been installed abreast, it is first-class to have assembled the welding machine more than 1 on each rotation circle, go up the welding head number of installing to the about 180 °/N(N of counter-rotation for each rotation circle mutually as long as make each rotation circle), can carry out the full week welding of pipe, thereby constitute High-Speed Automatic welder (inside and outside welding all can).
In addition, what be provided with by support ring, on the rotation circle parallel with the pipe weld root, at least assemble 1 welding head, simultaneously assemble several external clamps devices equidistantly, clamp the root of weld with the external clamps device after, available interior welds device carries out interior welds, after unclamping clamp, welding head is rotated along the root of weld can carry out outside weldings, thereby constitute inside and outside automatic soldering device of pipe.
The present invention and then may have such feature, on the rotation circle, welding head and subsidiary machine thereof can be installed simultaneously, also fit on preheat burner, abrasive machine and other machine respectively, can choose at random, carry out other processing when welding thereby be formed in, or weld the device with other processing respectively.
Also have such feature especially,, pipe is heated, can constitute the pressure-gas weld device of pipe by the burner nozzle that several pressure-gas welds are used is installed.
Of the present invention another be characterised in that, and be opposite with it except that the welder of said fixing pipe, also the rotation circle can be carried out suitably fixingly, by support ring pipe can be driven in rotation, thereby constitute the welder of rotation pipe.
Therefore, automatic soldering device of the present invention, particularly above-mentioned High-Speed Automatic welder and above-mentioned inside and outside automatic soldering device, optimum are made the on-the-spot weld job device of pipe laying engineering etc.It is characterized in that the device of the application of the invention can shorten weld interval 1/2nd to number/more than one, effect is remarkable.
Outside automatic soldering device in the past be outer disk at pipe around fixing metal band or chain, a chassis that is loaded with a welding head and subsidiary machine thereof is being supported to divide a word with a hyphen at the end of a line on the excircle of pipe and weld along the root of weld by this metal tape etc.
The welding of tube exterior will be carried out extremely several layers the welding of bonding layer (first welding bead), the second layer, in either case, because only be a welding head in the past, according to the layer number, it will carry out several repeatedly, for example, turn right about 180 ° from the summit of outside and to weld, get back to former starting point then, turn left again 180 ° and weld, get back to the full week welding that former starting point is just finished ground floor at last, so its shortcoming is to need the long activity duration, efficient is not high.
The present invention is for above-mentioned this point, at first be not use metal tape or chain etc., can rotate freely the support ring that the rotation circle is installed drivingly and be to use, this rotation circle can freely be driven in rotation, secondly, be not that welding machine is first-class that it is divided a word with a hyphen at the end of a line on metal tape in assembling on the chassis, but the rotation circle that can freely be driven in rotation be installed, and erection welding is first-class on this rotation circle by support ring.

In above-mentioned example, be respectively one because count N at each rotation circle welding head, so respectively rotating about 180 °, they just can finish circumference welding.
(5). following, when general description uses the invention described above device (on parallel rotation circle A, A ' 1 welding head C, C ' being installed respectively) to implement inside and outside welding of pipe once, the program of a welding interval.(with reference to the 6th figure, the 8th figure)
1. the opening of pipe P termination processing (being processed into special X opening).
2. the inner automatic soldering device of the present invention is set in fixing pipe P.
3. the single tube P that engages with need involutory (the present invention, the root gap of weld is 0)
4. the external clamps device is installed.
5. enforcement interior welds
6. unclamp external clamps
7. at pipe P outer setting outside automatic soldering device of the present invention
8. enforcement outside weldings.
Lifting an example, is that 771mm, thickness of slab are the steel pipe of 12.7mm concerning diameter, and all conditions of its inside and outside weldings are as follows:
The welding kind: CO2 welding connects
Cladding carbon dioxide: CO 2100%/ArO%
Cable size: 0.9mm
Welding condition speed of welding arc voltage welding current
(mm/min) (V) (A)
Bonding layer (interior welds) 750 26 260
The 2nd layer (outside weldings) 2,000 28 280
The 3rd layer of (outside weldings) 500 25 250
The 4th layer of (outside weldings) 350 22 220
Final layer (outside weldings) 330 21 180
When implementing welding with above-mentioned all conditions, the required arc duration of welding holostrome adds up to 21.7 minutes.And when using apparatus of the present invention because two rotation circles A, A ' rotate about 180 ° in the opposite direction and weld, thus arc duration only need its 1/2, got final product in about 11 minutes.
Promptly use apparatus of the present invention to implement inside and outside welding, than single-sided welding in the past, significantly improved efficient really.
So, bigger at the pipe bore, in the time of can carrying out the inside and outside welding, in the operation of for example pipe laying engineering etc., particularly at the scene in the operation, as using apparatus of the present invention, then can bring into play it and be several times as much as in the past high efficiency, and can bring into play the speciality of high-quality welding.
Use outside (single face) automatic soldering device, only pipe is carried out being necessary to form root completely under the situation of outside weldings.For this reason, root run only is suitable for the welding condition of little electric current low velocity, and welding efficiency is all very low usually.The scene welding of pipe laying engineering in the past mainly adopts the method to carry out, the efficient extreme difference.
As previously mentioned, can be formed in the High-Speed Automatic welder of inside and outside portion according to the present invention, as use this device to implement the inside and outside welding, its efficient will have tremendous raising.
Be welded as example with covered electrode arc welding, the MIG that carried out outside weldings in the past, bonding layer (ground floor at welding pipe, the 1st welding bead) and when the 2nd layer (the 2nd welding bead), its arc speed being compared as follows shown in the table with inside and outside carbon dioxide welding arc speed using apparatus of the present invention.
The present invention one
The inside and outside portion of welding kind (outside in the past) (outside in the past))
Arc speed coating electric welding TIG or MIG carbon dioxide
The welding of millimeter/itemize arc welding welding arc
First welding bead (bonding layer) 5-30 5-20 500-1200
(interior welds)
Second welding bead (the 2nd layer) 15-50 15-30 1000-2000
(outside weldings)
As previously mentioned, the reason that the velocity contrast of the previous methods that the speed of welding of apparatus of the present invention compares is bigger is, previous methods is because have only outside (single face) welding, so need to form root, this must set suitable root gap of weld, and to change various welding conditions according to various situations, cautiously implement welding.
And, carry out interior welds during then owing to beginning for device of the present invention, and do not need to form root, thus also needn't set the root gap of weld, and in welding, do not change welding condition, thus can weld in realization of High Speed with higher electric current, higher voltage.
Consequently carrying out inside and outside weld part that welds formation with apparatus of the present invention is demonstrating by abundant weldering to live in wholecircle week.Because speed of welding is fast, can not produce burning and drip phenomenon of motlten metal, so can obtain high welding precision and quality.
Apparatus of the present invention are opposite with conventional art, and mouth of pipe footpath is big more, and welding efficiency can improve more.
In the present invention promptly, the part of assembling welding head is rotated, so can assemble several welding heads on the rotation circle of large-diameter pipe.
When for example pipe diameter was 1 meter, if respectively assemble 2 welding heads on each the rotation circle that is parallel to each other, whole device was totally 4 welding heads, and then each welding head (i.e. rotation circle) is just rotation about 180 °/2 can be finished full week welding.In this case, the speed of welding of the 1st welding bead is as being 700 millimeters/minute, finishes the required time of the 1st welding bead to be about 1.5 minutes.It is 1/4 time of about previous methods.(with reference to the 9th figure)
Secondly, in inside and outside of the present invention automatic soldering device (with reference to the embodiment of the 10th, 11 figure), having assembled among at least one welding head C(figure on rotation circle A is 2) and several (being 6 among the figure) external clamps device D.
(ⅰ) rotation circle A has the structure of opening mode, is that fulcrum formation left and right sides open configuration hangs onto on the pipe with its top, with regulating nut the bottom is pinned then, it is installed on the support ring, and rotation is free.
(ⅱ) catch the butt joint pipe with the 12C of pressure apparatus portion, the 12b of clamp portion of external clamps device D then,, correct mouth of pipe dislocation with holding up the 12a of portion that its traction is come, and then with two Tube vices together.
(ⅲ) manage the bonding layer welding of internal weld seams root the inside with the interior welds machine.
After (ⅳ) interior welds is finished, unclamp the clamp (12b of clamp portion being risen) of external clamps device D with the pressure apparatus 12c of portion.
(ⅴ) rotate rotation circle A, welding head C is rotated along the root of weld, carry out outside weldings.
In the drawings, assembling 2 welding heads on the basic symmetrical position up and down, top welding head C rotates and welds, finish when welding to the pipe bottom, bottom welding head C ' is in the position at pipe top, along with rotation circle to counter-rotation, just from top to bottom the opposite side of pipe is welded, thereby finishes the full week welding of pipe.
(ⅵ) as mentioned above, owing to can implement outside clamping, interior welds and outside weldings continuously, saved the loading and unloading of special-purpose external clamps device in the past and miscellaneous work such as loading and unloading of special external welder, thereby the whole weld job time is obviously shortened.
(ⅶ) in addition, when using special external gripping mechanism holder tube in the past, differing is positioned on the clamp brake shoe the bigger place of dislocation surely, therefore can't bring into play its usefulness effectively.This is a shortcoming.
In the present invention, external clamps device D is assemblied on the rotation circle A, thereby can freely rotate rotation circle A clamping is carried out in the optimum position that external clamps device D moves on to necessity, thereby can effectively, rapidly and critically correct dislocation.
Be that the result of the pipeline welding field conduct of 720mm shows (ⅷ) at diameter, the loading and unloading, the mobile operating that are equivalent to 1 weld seam, need 20 minutes with in the past special external gripping mechanism and special external welder, and use device of the present invention only to get final product with about 10 minutes.
Facts have proved, requiring than significantly shortening under the situation of time in the past,, when carrying out the interior external welding of pipe, use apparatus of the present invention and have better effect as the weld job of laying long-distance pipe and submarine pipeline.
In addition, as previously mentioned, the present invention also has such characteristics, the machine of installing on the rotation circle is except that welding head and subsidiary machine thereof, also can assemble preheat burner, abrasive machine and other corresponding machine, thereby a kind of device is provided, perhaps in welding, carry out other processing, perhaps weld respectively and other processing, can choose at random.
And, by several burner nozzles of fit on pipe is heated, also can provide the pressure-gas weld device.
And then the rotation circle that is equipped with welding head can be carried out suitably fixing, and suitably rotation drives support ring and pipe, constitutes the automatic soldering device of swivelling pipe etc.Can so bring into play its multiple good speciality.
