Abstract

Provided is a welding device capable of double-side automatic welding for a pipe and a flange. The welding device comprises an inner welding device and an outer welding device. The inner welding device and the outer welding device are each provided with a support which stands on a base, a sleeve pipe I and a fastening bolt which are used for fixing a beam on the support, a welding gun sleeve pipe which is used for fixing a welding gun on the beam, and a welding gun swing machine which is installed on the sleeve pipe. The welding gun sleeve pipes are connected with sleeve pipes II on the beams. The inner welding device and the outer welding device are welded to an interior angle welding line of the flange and an exterior angle welding line of the pipe respectively. The pipe is fixed on a compressing roller dislodgement machine. According to the welding device, the structure is simple, the simple structured inner welding device and outer welding device is only needed to be added onto the whole welding device on the basis of the original compressing roller dislodgement machine, and the operation of a worker is flexible and convenient. The welding method adopts a carbon dioxide gas shield welding method, so that the application range is wide, a synchronously symmetrical automatic welding is achieved on the interior angle welding line and the exterior angle welding line, the welding deformation is reduced, the welding efficiency is improved, the work load of the worker is reduced without needing a huge amount of capital investment, and the production efficiency is improved.

Description

The welder of a kind of pipe and the two-sided automatic welding of flange
Technical field
The present invention relates to the welder of the two-sided automatic welding of outside fillet (weld) in a kind of pipe and flange.
Background technology
There is a large amount of tube structures in boats and ships ocean engineering industry, in these tube structures, considerable part is made up of pipe and Flange joint.Therefore be one of groundwork of piping construction at tube end welded flange.The main welding method of current employing is artificial or utilizes positioner to be rotated by pipe, implements welding of interior angle and outside fillet (weld) by artificial respectively at two ends to pipe and flange connections, and the workload of this method workman is large, production efficiency and quality lower.
Very large achievement in research is achieved through unremitting effort at present for the problems referred to above China scientific research personnel.Publication number is the patent documents such as CN2327493, CN101733593, CN201841391, invent the machine of automatic welding flange, substantially solve workman and weld tedious problem, but machine welds nobody's work, and welding is flexible and changeable, and the complicated high cost of device structure, general enterprises is difficult to accept.Publication number is the patent of CN102728938, has invented the inside and outside two-sided welding device of a kind of steel pipe and flange, mainly the hoop butt weld of welded flange and steel pipe, and be not suitable for welding corner connection weld seam, and take submerged-arc welding method, flexibility ratio is poor.
Summary of the invention
The object of the present invention is to provide one can reduce workman's flange welding amount of labour, facilitate workman's welding job, improve the pipe of welding efficiency and the welder of the two-sided automatic welding of flange.
The technical solution used in the present invention is:
The welder of a kind of pipe and the two-sided automatic welding of flange, comprise internal welding device and outer welder, described internal welding device and outer welder include with the pillar stood on base, make crossbeam be fixed on the sleeve pipe I of pillar and fastening bolt, make welding gun be fixed on welding gun sleeve pipe on crossbeam, install and oscillator of welding gun on sleeve pipe, described welding gun sleeve pipe connects with the sleeve pipe II on crossbeam, the inside fillet of described internal welding device and outer welder difference welded flange and pipe and outside fillet (weld), described pipe is fixed on pinch rollers positioner.
When using welding pipe of the present invention and flange, take carbon dioxide gas shielded welding method, use internal welding device to weld with outside fillet (weld) in flange pipe with outer welder respectively simultaneously.First pipe lifting is fixed to level on pinch rollers positioner, flange and pipe spot welding are fixed, internal welding device and outer welder lay respectively at pipe both sides, the sleeve pipe on column and crossbeam and fastening bolt is utilized to regulate the position of welding gun, by sleeve pipe adjustment angle of welding gun on swing bolster, bottom the welding gun alignment flange of internal welding device and the inside fillet of pipe, by the welding gun alignment flange of outer welder and the outside fillet (weld) top of pipe, compress pipe by pinch rollers positioner to rotate, press interior weldering, the welding gun starting the arc button of outer welder, the swing of welding gun is controlled by oscillator of welding gun, can realize the synchronous symmetrical automatic welding of pipe with outside fillet (weld) in flange.
Advantage of the present invention: structure is simple, a whole set of welder only need increase the simple internal welding device of structure and outer welder on the basis of original pinch rollers positioner, operative is flexible, the welding method that welding method takes specialized for carbon dioxide gas protection to weld, applied widely, the synchronous symmetrical automatic welding of interior outside fillet (weld), reduce welding deformation, improve welding efficiency, do not need a large amount of capital to drop into and just can reach the reduction workman amount of labour, the beneficial effect of enhancing productivity.

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the structural representation of welder of the present invention;
Fig. 2 is the angle welding structural representation of pipe and flange welding.
In figure: 1, internal welding device; 2, outer welder; 3, base; 4, column; 5, crossbeam; 6, sleeve pipe I; 7, fastening bolt; 8, welding gun sleeve pipe; 9, welding gun; 10, pinch rollers positioner; 11, pipe; 12, flange; 13, oscillator of welding gun; 14, inside fillet; 15, outside fillet (weld); 16, sleeve pipe II.
Detailed description of the invention
As Fig. 1, shown in 2, the welder of a kind of pipe and the two-sided automatic welding of flange, comprise internal welding device 1 and outer welder 2, described internal welding device and outer welder include and the pillar 4 stood on base 3, crossbeam 5 is made to be fixed on sleeve pipe I 6 and the fastening bolt 7 of pillar, welding gun 9 is made to be fixed on welding gun sleeve pipe 8 on crossbeam, install and the oscillator of welding gun 13 on sleeve pipe, described welding gun sleeve pipe connects with the sleeve pipe II 16 on crossbeam, the inside fillet 14 of described internal welding device and outer welder difference welded flange 12 and pipe 11 and outside fillet (weld) 15, described pipe is fixed on pinch rollers positioner 10, structure of the present invention is simple, a whole set of welder only need increase the simple internal welding device of structure and outer welder on the basis of original pinch rollers positioner, operative is flexible, the welding method that welding method takes specialized for carbon dioxide gas protection to weld, applied widely, the synchronous symmetrical automatic welding of interior outside fillet (weld), reduce welding deformation, improve welding efficiency, do not need a large amount of capital to drop into and just can reach the reduction workman amount of labour, the beneficial effect of enhancing productivity.
