Self aligned welding rotator technical requirements

- Jun 30, 2019-

 (1) Automatically adjust the swing angle of the wheel set according to the diameter of the workpiece, and can automatically adjust the center. When the self aligned welding rotator is matched with the welding operation machine and the welding power source, the inner and outer longitudinal joints of the workpiece and the inner and outer circumferential seam welding can be realized.


(2) Appropriate adjustment of the height of the main and driven rollers, as well as assembly and welding of cones and segmented unequal-diameter rotors.

The transmission noise is low and the workpiece rotates smoothly. The process of welding, polishing, lining and assembly of the cylindrical cylinder can be realized. The rotation speed of the roller should be stable and uniform. No crawling is allowed.


(3) It must have over-voltage protection, self-protection function, fault display and storage function, automatic air switch short-circuit protection, and preset parameters.


(4) For some non-circular long-shaped weldments, they are stuck in a special annular clamp, and can also be welded on the welding roller frame.


(5) Self aligned welding rotator adopts digital adjustment and display technology for the rotation speed of the roller. The setting of welding speed is very intuitive and accurate, which reduces the difficulty of operation of workers.


(6) The manufacturing and assembly accuracy of the roller frame should meet the accuracy requirements of class 8. The roller frame should be made of high-quality steel, such as a pedestal with a welded structure, which must be subjected to stress-relieving heat treatment.


(7) The roller frame must be equipped with a reliable conductive device that does not allow the welding current to flow through the bearings of the roller frame.


(8) When the cylinder-like workpiece is welded on the anti-axial rolling roller frame, the axial movement of the workpiece during the whole welding process shall be ≤ ± 3 mm.


(9) The center distance of each pair of rollers of the roller frame must be adjusted according to the diameter of the cylinder-like workpiece to ensure that the wrap angle of the two rollers is 45° larger than 110°.


(10) Roller frame with 15m control cable, roller positive and negative switch, near control, remote control switch.
