Description
Technical field
the invention belongs to welding technology field, particularly relate to the automatic double-sided welder of steel welded tube.
Background technology
The weld seam of
big caliber, heavy wall steel welded tube generally all need adopt welding by both sides technology, to guarantee the quality of welded tube.At present, domestic steel welded tube welding by both sides technology is divided into manual welding and weldering automatically.Manual welding is that weldering welded tube out-seam welds inseam more earlier, and its welding work efficiency is low, and labour intensity is big, and welding quality is difficult to guarantee, and is unwell to the welded tube of the inaccessiable less caliber of human body.And automatically weldering is the skelp pipe straight ahead at the uniform velocity on device that makes the steel plate roll-forming through transmission mechanism; On device, be fixed with outer welding gun and the interior welding gun to skelp pipe weld seam simultaneously, wherein interior welding gun is to be installed on the long cantilever that can stretch in the steel pipe.Automatically the shortcoming of weldering internal welding device existence is, overall structure is bulky, controls trouble, and owing to temperature in the welded tube is high, poor radiation, welding gun scaling loss in often causing; In addition,, regulate interior welding gun real-time tracking weld seam deviation, so often be prone to take place the inclined to one side and welding undercut phenomenon of weldering and can't handle because of observing weldering situation in the welded tube.
Summary of the invention
the object of the invention, provide a kind of simple for structure, control convenient and the automatic double-sided welder of steel welded tube vertical masonry joint can the real-time tracking weld seam.
technical scheme of the present invention is: the automatic double-sided welder of a kind of steel welded tube vertical masonry joint; Comprise steel welded tube transmission device, outside weld welding gun, inside weld welding gun; And relative outside weld welding gun is provided with the welding protection gas hood in the steel welded tube, and said welding protection gas hood is installed on two disc holders; The inside weld welding gun is installed on the lateral surface of the preceding disk of said pair of disc holder through the movable link rod of two dimension; On the lateral surface of preceding disk the monitor to steel welded tube inside weld is installed also simultaneously, monitor all connects with electric controller with the inside weld welding gun mutually, and said pair of disc holder is connected with frame through horizontal link rod.
as preferred, said welding protection gas hood bottom is provided with spring supporting device.
as preferred, said welding protection gas hood bottom is provided with water-cooling apparatus.
as preferred, the preceding disk of said pair of disc holder, the bottom and the left and right side of rear disk are respectively equipped with flexible block.
as preferred, the material of said flexible block is a nylon.
as preferred, said outside weld welding gun is for adding metal filled silk plasma gun.
as preferred, said inside weld welding gun is the automatic tungsten anode argon arc welding welding gun.
as preferred, the monitor of steel welded tube inside weld is a video camera.
as preferred, the movable link rod of said two dimension is electronic cross sled mechanism.
the invention has the beneficial effects as follows: with traditional being controlled and stretched into and manage interior bulky interior welding gun cantilever by the outer mechanical transmission mechanism of pipe; Be improved to and directly be installed on the dexterous electronic cross sled mechanism on the gas shroud support in the pipe; Set up steel welded tube inside weld monitor simultaneously; According to the signal that monitor sends, control electronic cross sled mechanism action by electric control gear, welding gun is aimed at the inside weld of steel welded tube all the time in making; In addition, the water-cooling apparatus that is provided with in welding protection gas hood bottom effectively reduces temperature in the steel welded tube, has guaranteed the safety of interior welding gun, and it is identical that spring supporting device remains with the steel inner wall of welded pipe protection gas hood, improved the welding protection effect.The present invention organically assembles one with interior protection device of air, water cooling plant, interior welding gun adjusting device and supervising device, and its compact conformation, volume are little, operation automatically, reliable welding quality, efficient are high, are specially adapted to Φ 219～Φ 630 steel welded tubes.
