Dress, this frock includes bracing frame and the relative two bend pipe folder being arranged at bracing frame both sides, first divides two bend pipes during welding
It is not clamped in each self-corresponding bend pipe folder and so that its weld port is docked, the top of spot welding fixed bending tube, on advanced line pipe body
The welding in portion, then welder lie in and under bend pipe, bend pipe welded in the overhead position；This kind of method exists：1st, bend pipe overhead welding is not only operated
Difficulty and potential safety hazard height, and high labor intensive, inefficiency；2nd, when welding various sizes of bend pipe, need to manufacture
Go out various various sizes of frocks, the quantity of frock is many, frock construction cost is high, the problem of inconvenience management.
Content of the invention
The technical problem to be solved is to provide a kind of elbow pipe welding method, and this method can solve existing curved
During pipe overhead welding, potential safety hazard is high, inefficiency and the many construction cost of frock quantity are high, the problem of inconvenience management.
In order to solve the above problems, the technical solution adopted in the present invention is：This elbow pipe welding method, curved using one kind
Sealing of tube frock, this frock includes base plate, a pair of supporting being arranged on this base plate and passes through its shaft set respective
On corresponding support frame as described above and be located at corner bracket between this pair of supporting, the outside of support frame as described above is equipped with identical and moves
Power machine, the output shaft of described engine is all connected with each self-corresponding described rotating shaft；Described corner bracket is provided with opposite two
Workpiece supporting plate, described workpiece supporting plate one end is all hinged with each self-corresponding described corner bracket, its other end all be fixed on
Adjustable plate on described corner bracket is flexibly connected；Workpiece clamping card is equipped with described workpiece supporting plate；
Described corner bracket includes horizontal part and vertical portion, and two described workpiece supporting plates are respectively arranged at the institute of two corner brackets
State horizontal part, described rotating shaft is installed on the described vertical portion of two corner brackets respectively, and is connected with the output shaft of engine respectively
Connect；
Described Workpiece clamping card includes all offering the upper and lower of V-groove thereon, and described upper and lower sets relatively
Put, its one end is connected by hinge, the other end is provided with mutually corresponding lock；
Its operating procedure is as follows：
A, the groove being 53 degree by the bend loss angle of release degree needing welding；
B, the described workpiece of the relative arranged on left and right sides being placed in described base plate of bend loss groove that step a is held successfully groove prop up
On fagging, and make between described groove, to reserve 1.5 millimeters of gap, then tighten described Workpiece clamping card respectively；
C, start described engine simultaneously, tack welding is carried out to described bend loss and is fixed, recycle argon arc welding to it
Carry out bottoming welding；
D, complete the welding of whole bend pipe with arc welding.
Due to employing technique scheme, the present invention compared with prior art has the advantages that：
1st, due to being provided with the corner bracket that its rotating shaft is connected with bracing frame between a pair of supporting, corner bracket is provided with phase
To two workpiece supporting plates, workpiece supporting plate one end is all hinged with each self-corresponding corner bracket, its other end all be fixed on
Adjustable plate on each self-corresponding corner bracket is flexibly connected, and workpiece supporting plate is equipped with Workpiece clamping card；And bracing frame is outer
Side is equipped with identical engine, and the output shaft of engine is all connected with the rotating shaft of each self-corresponding corner bracket；During welding first
Adjust the gradient of two workpiece supporting plates according to Design Requirement Drawing, then two bend pipes are respectively placed in corresponding workpiece support
On plate, so that weld port is docked, and clamp, then activate switch makes two engines rotate simultaneously, welded it is not necessary to
Workman welds in the overhead position, the bend pipe board size being simultaneously welded into is not accurately overproof, it is to avoid phenomenon of doing over again, and has saved production time and production
Cost.
2nd, because the gradient of two workpiece supporting plates is all adjustable, adapt to weld the curved of various different curvature radius sizes
Pipe, conveniently manages and reduces production cost.
