Boiler Industries / Pressure Vessel Pipe Welding Rotator Self Aligned

1. Equipment instruction

        Welding manipulator can be composed of auto welding mechanical equipment via welding rotator, welding positioner. It is used for internal and external circular welding seam ,fillet weld and internal and external longitudinal welding seam it has functions of moving, rotating, elevating and traversing.

        Welding rotator is widely used in metal cylinder of transmission of automatic welding, is the indispensably special equipment for automatic welding of all kinds of pressure vessel. This equipment consists of power rotator and idler rotator. The tilt angle of roller group can be automatic adjusted by work-piece. It has advantages of reliable quality, superior performance, simple operation etc.

        Automatic welding center is mainly composed of welding manipulator, floor turntable positioner and welding source. When working, the fist is to make piece on the floor turntable positioner and turn welding rotator to make the work-piece stay to weld by process requirements. Then make welding torch adjust to a certain welding position through kinds of movement of welding manipulator. At the last ,start welding machine and rotate work-piece by positioner to realize automatic welding.

3. Performance feature

        Welding manipulator is composed of column, boom, nose and elevating. Column is rectangle, and on its top there is boom elevating mechanism which is dual beam. The motor drives worm gear and worm reducer and drives sprocket and chain . One end of chain is connected with boom guide device, and the other end is fixed on balance iron in column. There are eight groups of pulley block which is eccentric shaft structure on boom guide seat. Elevating and flexing of boom is controlled by AC variable frequency speed regulation which can be adjusted according to welding needs. Automatic welding machine head is fixed on front of the boom, and the nose can be trimming up and down, right and left.

        Conventional welding rotator is composed of power rotator and idler rotator. power rotator has advantage of driving rotator turning to make work-piece rotate. It has high load capacity ,and the line speed meets the requirements of welding ,adopting AC variable frequency speed regulation. Idler rotator is same as driven rotator, playing the supporting role but unpowered,and it turns by the work-piece friction. This Equipment consists of power rotator and idler rotator. The tilt angle of roller group can be manual adjusted by screw. It has advantages of reliable quality, superior performance, simple operation etc.

        The complete set of equipment adopts advanced trinity centralized control mode. It means that welding manipulator, welding positioner and functions of welding machine can be fused together organically to realize welding better. At the same time , it is also equipped with a remote control box which has all operation functions of this machine to operate conveniently.

4. Scope of supply

Welding manipulator: including column and boom, elevator mechanism, rotating mechanism, electronic control system

Welding rotator: usually one set rotator including one power rotator and one idler rotator, also you could match the amount according to your plan

Welding source: Lincoln welder series of provide by buyer

Flux recycle system is an option which is depends on customer, if you want you should buy it separately
