Abstract
The invention discloses a welding method for a flange plate on a tubular or tank container opening, and relates to a welding method of assembly products. After the opening of a tubular or tank container body is leveled, the flange plate is tightly attached to the opening of the container body, with the same axes as the body; then at least two welding spots are symmetrically welded on a peripheral seam between the flange plate and the opening, so as to fixedly connect the flange plate and the opening with a certain strength; the flange plate and the container body which are connected are clamped on a welding frame of a first and a second rotating chucks which have the same axial line, and the end to be welded is forward; then the height of the rotating chuck at the back end is risen to keep an angle of 39-52 degrees between the axial line and a horizontal plane; finally, parts to be clamped are rotated for continuously welding the peripheral seam. The connection dimension of the formed seam on two parts is more reasonable, which ensures higher welding firmness.
Description
Technical field
The present invention relates to a kind of welding processing of subassembly product, relate in particular to the welding method of pipe, pot container oral area ring flange.
Background technology
Aluminium matter bus pipe, hermetically sealed can port part need to arrange adpting flange.Add man-hour for this series products, ring flange generally is by being welded to connect.At present, when carrying out above-mentioned welding processing, generally be: Xian Qikou, again with the ring flange tack-weld at port, then, workpiece is prevented on turning rolls, drive the rotation of workpiece limit, side weld connects.But in the processing, we find, owing to there not being the clamping measure, the situation of " having climbed ", " beating " often appears in workpiece the rotation worker, and weld seam is inhomogeneous, plumb joint departs from weld seam so that workpiece exists, quality problems are not just being waited at the center.In addition, no matter be the horizontal positioned of long part, or short upright placement, during welding, welding pool is owing to the gravity reason, the section of weld joint that forms is the right angled triangle with long limit and minor face, and long limit/minor face is attached to respectively ring flange end face or mouth of pipe outer surface, so that inconsistent at the degree of being connected firmly of this two places welding.
Summary of the invention
The present invention is directed to above problem, provide a kind of rotational stabilization good, and even weld, thereby make that welding precision is high, the welding method of the measured pipe of matter, pot container oral area ring flange.
Technical scheme of the present invention is: behind pipe, the neat mouth of pot container body that ring flange is sturdy in the oral area of body, keep ring flange and body concentric; Two solder joints of spot welding at least symmetrically on both circumferential seams are fixedly linked both with having some strength again; Both that are connected as a single entity are clamped on rotating chuck one with coaxial line, two the weld holder, need an end of welding forward; Then, improve the height of rear end rotating chuck two, make described axis horizontal by 39-52 ° of angle; At last, rotation is held part, and the circumferential seam is carried out continuous welding.
Rotating chuck one on the described weld holder is hinged on the front portion of weld holder by a horizontal hinge shaft; Described rotating chuck two and a lowering or hoisting gear are movably connected; Described lowering or hoisting gear drives rotating chuck two actions, can change rotating chuck one, two axis and the angle of horizontal plane.
Rotating chuck one, two bottom are respectively equipped with the positioner that makes both initial bit axis coaxles and level.
The present invention has at first changed and has carried out this type of in the past and add man-hour, and workpiece is the situation of clamping not, behind workpiece elder generation spot welding one location, carry out clamping, thereby the workpiece seam is with respect to the positional precision of automatic welding gun when having guaranteed automatic welding again; Secondly, changed when welding in the past, workpiece is in the placement form of level or erectility, changes the position slant setting, and workpiece tilts 45 ° when placing, the liquid level energy maintenance level of welding pool, after solidifying, weld seam is isosceles right triangle, with respect to the weld seam of prior art, the weld seam that the present invention forms is more reasonable in the size that two parts connect, so that firm welding Du Genggao.Consider the difference of different-thickness part thermal stress, intensity etc., the angle of inclination is arranged in the scope, thereby makes adaptability of the present invention stronger.

The specific embodiment
The present invention as Figure 1-3, and is behind pipe, the pot container body 7 neat mouths that ring flange 5 is sturdy in the oral area of body 7, keeps ring flange 5 and body 7 concentrics; Two solder joints of spot welding at least symmetrically on both circumferential seams are fixedly linked both with having some strength again; Both that are connected as a single entity are clamped on the weld holder 1 of rotating chuck 1 with coaxial line, rotating chuck 28, need an end of welding forward; Then, improve the height of rear end rotating chuck 28, make described axis horizontal by 39-52 ° of angle; At last, rotation is held part, utilizes automatic welding gun 6 to carry out continuous welding to the circumferential seam.
After being soldered an end flanges dish, the workpiece of backing off repeats above-mentioned steps, welding other end ring flange.At this moment, the end that welding is good becomes the rear end, and having the cross section is the weld seam 11 that the right angled triangle rear end has welded, and wherein an acute angle is 39-52 ° of angle.As shown in Figure 3, has better quality of connection between rear end ring flange 12 and the body 7.
Rotating chuck 1 on the described weld holder 1 is hinged on the front portion of weld holder 1 by a horizontal hinge shaft 2; Described rotating chuck 28 and a lowering or hoisting gear 9 are movably connected; Described lowering or hoisting gear 8 drives rotating chuck 28 and does lifting action, can change the axis of rotating chuck 1, rotating chuck 28 and the angle of horizontal plane.
The bottom of rotating chuck 1, rotating chuck 28 is respectively equipped with the positioner that makes both initial bit axis coaxles and level.
