Description

The built-in bonding pad roll device of middle steel pipes with straight outside weld
Technical field:
The utility model relates to the built-in bonding pad roll device of steel pipe outside weld.
Background technology:
Existing bonding pad roll device uses when being applicable to weldering in steel pipe, namely when carrying out interior weldering submerged-arc welding to steel pipe, bonding pad roll is placed in the bottom of steel pipe, its weak point is the interior weldering submerged-arc welding process that cannot be applicable to more than two, it easily causes solder flux to stop and produces open arc in addition, need manual repair after producing open arc, add the labour intensity of workman.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of outside weld submerged-arc welding process being applicable to more than two, solder flux can not be caused to stop and produce the built-in bonding pad roll device of middle steel pipes with straight outside weld of open arc.
Above-mentioned purpose is achieved in that it comprises oil cylinder, cylinder base and the backing roll roll stand of oil cylinder are connected and fixed, before, latter two backing roll is arranged in backing roll roll stand respectively by respective axle, bonding pad roll roll stand is fixed on the cylinder bar of oil cylinder, bonding pad roll is contained in bonding pad roll roll stand by axle, also comprise connecting rod, connecting rod one end is fixed on the cylinder body of oil cylinder, the other end of connecting rod is fixed on the crossbeam of steel pipe precisive shaped frame, two registration rollers are provided with between bonding pad roll and steel pipe precisive shaped frame, two registration rollers are contained in registration roller roll stand respectively by respective axle, registration roller roll stand is connected with one end of positive left-hand thread screw mandrel, the other end of positive left-hand thread screw mandrel is connected with bonding pad roll roll stand.
The utility model has the advantages that: be placed in steel pipe by this device during use, adjustment oil cylinder, makes two registration rollers heal up with steel pipe respectively two the tube wall ends contact located, and bonding pad roll and steel pipe heal up and locate lower surface and contact, and then carry out weld job.It is applicable to the outside weld submerged-arc welding process of more than two, solder flux can not be caused to stop and produce open arc, without the need to manual repair, alleviating the labour intensity of workman.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model, and in figure, 9 is steel pipes, and 10 is crossbeams of steel pipe precisive shaped frame, and 11 is steel pipe precisive shaped frames;
Fig. 2 is the A direction view of Fig. 1, and in figure, 9 is steel pipes;
Fig. 3 is the B direction view of Fig. 1, and in figure, 9 is steel pipes.
Detailed description of the invention:
With reference to Fig. 1-3, it comprises oil cylinder 1, cylinder base and the backing roll roll stand 2 of oil cylinder are connected and fixed, before, latter two backing roll 3 is arranged in backing roll roll stand respectively by respective axle, bonding pad roll roll stand 4 is fixed on the cylinder bar of oil cylinder, bonding pad roll 5 is contained in bonding pad roll roll stand by axle, also comprise connecting rod 6, connecting rod one end is fixed on the cylinder body of oil cylinder, the other end of connecting rod is fixed on the crossbeam of steel pipe precisive shaped frame, two registration rollers 7 are provided with between bonding pad roll and steel pipe precisive shaped frame, two registration rollers are contained in registration roller roll stand respectively by respective axle, registration roller roll stand is connected with one end of positive left-hand thread screw mandrel 8, the other end of positive left-hand thread screw mandrel is connected with bonding pad roll roll stand.
