Pipe Positioners Pipe Rotators for Welding , Rotary Welding Table

Quick Detail:

Positioners provide steel fabrication shops with the most up-to-date equipment for placing bulky fabrications in the ‘downhand’ position in the shortest possible time without the use of cranes and manpower. The positioners tables rotate at accurate and constant variable speeds and tilt through 135° with a high C.G. load rating covering almost all anglers for welding any angular job placed on it. Positioners can be supplied for interfacing with Column and Boom Manipulator.


Description:

The equipment mainly consists of drive rotator, idler rotator and electrical control system etc. Drive rotator

is made up of base, pedestal, rollers and drive device, idler rotator without drive device.

1:pedestal and roller base are welded structure, all the strength of the weld seam according to

requirements such as welding, heat treatment after welding were annealed to remove internal stress and

effective prevention of welding deformation.

2:Drive device located on the two roller beds of the droved rotator, Drive device are consist of reducer

and motor. The reducer adopts the special design gear and wheel reducer and which made by our

company, with high transmission efficiency, large output moment. Drive unit droved by AC frequency

conversion motor, and through reducer, thus drive the roller turning. The turning speed is VFD, and the

speed can be adjusted in the range of 100-1000mm/min, and it can realize different welding requirement

of different size work piece. Both drive and idler rotator equipped with traveling unit, easy for operating,

and the idler unit with manual lock device, it can quick lock rotator on the rail. On the base of drive rotator

equipped with a set of traveling motor, and traveling consists by two bevel gear reducer and two 1.5 KW

motor, gear and wheel couple, and the drive and idler rotator droved on the rail by bevel gear reducer and

gear and rack couple, traveling smoothly and convenient operating.

3:The rollers are all Polyurethane material and without metal. Roller center distance can be adjusted to

realize different size workpiece. When adjusting, just move the position of symmetrical roller seat, then

fixed by bolts, easy and convenient, also with large anti-wallop strength..

4:The equipment side of the idler rotator fitted with a mechanical gear wheel, gear wheel fixed in the holder

with the rotating cylinder, while the rotation of power, to meet the welding requirements of different size

cylinder workpiece, to prevent the shifting of the workpiece in the welding process holder behind the

installation of a locking device to prevent the roller frame roll.

5:Electric control system mainly consists of electric control box and remote panel. There are inverter, relay,

terminal etc in the control box. Power switch is mounted on the door of electric control box. The alarm

indication, alarm clear button on the panel of control box; the remote panel has roller forward, backward,

stop button.

Applications:

This bolt adjustable welding rotator is produced according to MMBEI Standard ZBJ33003-1990.

Self-design and manufacture combined the advantages of oversea competitors and requirements of

domestic and overseas customers. It is suitable for automatic welding of circular seam cylinder, with

advantages of practical, reliable, stable and easily operates etc. It is widely used in the range of job

cutting, polishing, assemble etc.. It is one of ideal equipments of improve automaticity and efficiency.
