Product Description

The screw welding roller uses a rocker-type handwheel to adjust the distance of the roller.

The working principle of the drive and idler welding rotator:

The center distance of the roller group is adjusted by grouping and matching between the moving wheel frame and the screw hole group reserved on the base to adapt to the needs of the work-piece diameter change.
In addition to acting on circular work-piece, it can also be equipped with corresponding auxiliary tooling (such as a special ring clamp) for welding some non-circular elongated work-piece.

The welding turning roller can be one drive with one idler, one drive with two idlers, or one drive with three idlers, according to the actual needs of customers.

Faults and solutions that are prone to occur during the use of the welding roller rotator:
 

No.	Phenomenon	Reasons	Measures
1	The motor does not turn and the indicator light does not light up	The three-phase voltage is not connected to the control box (or external problems)	Check for external factors
2	The motor does not turn, the indicator light is on	1. Inverter overload protection 2. Motor damage	1. Manually reset the inverter 2. Replace the motor
3	Offset to one side when the workpiece is turned	The drive/idler roller frame is not on the same plane, or the center diagonal of the master-slave roller frame is not corrected	Check the flatness and correct the center diagonal of the master-slave roller frame

 

Welding rotator lubrication and maintenance:
1. Worm gear reducer: Before operation, open the protective cover of the reducer and add lubricating oil to above the center point of the oil mark, replace it after 24 hours of first use, and replace it every 500-1000 hours after that, and remove the vent hole and then install the screw (Special warning: It is strictly forbidden to use without refueling!)
2. Slewing bearing: The bearing cover of the welding roller frame can be opened for regular lubrication. It is recommended to use lithium-based ester
3. Regular lubrication inspection: In order to ensure the performance of the self-adjusting pipe welding roller rotator and prolong the service life, all transmission parts should be regularly lubricated and inspected, and the reducer must be inspected every month to supplement the lubricating grease.
4. Add lubricating oil to the rotary adjustable welding turning rolls reducer and bearings.
