When utilizing the conveying supporting body of pipeline as medium stream, the reason of Chang Yinwei landform wants bending, being welded to each other of what the bending of usual pipeline adopted is joint or two different directions pipelines, existing elbow pipe welding method adopts a kind of bend welding tool, this frock includes bracing frame and two the relative bend pipe folders being arranged at bracing frame both sides, first two bend pipes to be clamped in respectively during welding in respective bend pipe folder and its weld port is docked, the top of spot welding fixed bending tube, the welding on advanced line pipe body top, then welder welds in the overhead position to bend pipe under lying in bend pipe; This kind of method also exists: 1, to weld in the overhead position not only operating difficulties and potential safety hazard is high to bend pipe, and labour intensity is large, inefficiency; 2, when welding the bend pipe of different size, need the frock producing various different size, the quantity of frock is many, and frock construction cost is high, the problem of inconvenience management.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of elbow pipe welding method, this method can solve existing bend pipe overhead welding time, potential safety hazard is high, inefficiency and the many construction cost of frock quantity high, inconvenience management problem.
In order to solve the problem, the technical solution adopted in the present invention is: this elbow pipe welding method, adopt a kind of bend welding tool, this frock includes base plate, be arranged at pair of supporting on this base plate and by the corner bracket of its shaft set on respective support frame as described above and between this pair of supporting, the outside of support frame as described above is equipped with identical engine, and the output shaft of described engine is all connected with respective described rotating shaft; Described corner bracket is provided with two workpiece supporting plates in opposite directions, and described workpiece supporting plate one end is all hinged with respective described corner bracket, and its other end is all flexibly connected with the adjustable plate be fixed on described corner bracket; Described workpiece supporting plate is equipped with Workpiece clamping card;
Described corner bracket includes horizontal part and vertical portion, and two described workpiece supporting plates are all arranged on respective described horizontal part, and described rotating shaft is all installed on respective described vertical portion and is connected with the output shaft of respective described engine;
Described Workpiece clamping card comprises the upper and lower it all offering V-type groove, and described upper and lower is oppositely arranged, and its one end is connected by hinge, and the other end is provided with mutually corresponding snap close;
Its operating procedure is as follows:
A, will the bend loss angle of release degree of welding be needed to be the groove of 53 degree;
B, bend loss groove step a being held successfully groove are placed on the described workpiece supporting plate of the arranged on left and right sides of described base plate relatively, and make the gap of between described groove reserved 1.5 millimeters, then tighten described Workpiece clamping card respectively;
C, start described electric power machine simultaneously, carry out tack welding be fixed to described bend loss, recycling argon arc welding carries out bottoming welding to it;
D, complete the welding of whole bend pipe by arc welding.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to being provided with the corner bracket that its rotating shaft is connected with bracing frame between pair of supporting, corner bracket is provided with two workpiece supporting plates in opposite directions, workpiece supporting plate one end is all hinged with respective corner bracket, its other end is all flexibly connected with the adjustable plate be fixed on respective corner bracket, workpiece supporting plate is equipped with Workpiece clamping card; And the outside of bracing frame is equipped with identical engine, the output shaft of engine is all connected with the rotating shaft of respective corner bracket; First adjust the gradient of two workpiece supporting plates according to Design Requirement Drawing during welding, again two bend pipes are placed on corresponding workpiece supporting plate respectively, weld port is docked, and clamp, then starting switch makes two engines rotate simultaneously, welds, workman is not needed to weld in the overhead position, the bend pipe board size be simultaneously welded into is accurately not overproof, avoids phenomenon of doing over again, has saved production time and production cost.
2, the gradient due to two workpiece supporting plates is all adjustable, adapts to the bend pipe of the various different curvature radius size of welding, conveniently manages and reduce production cost.
