1. The welding roller rack can be divided into two different forms, one is self-adjustable welding roller rack, the other is adjustable welding roller rack. The four rollers on the active rack are driven by full gear meshing, which effectively realizes the four-wheel drive. One of them belongs to the active roller rack, and the other belongs to the driven roller rack. Both of them can be directly fixed on the position, of course, can also be directly installed on the track.

2. Under normal conditions, the welding roller rack is used in combination. According to the size of the workpiece in diameter, the swing angle of the roller group can be automatically adjusted, so there is no need for manual adjustment.

3. Lastly, because the imported frequency converter is used in the welding roller rack to adjust the speed steplessly, it is relatively wide in the whole range of adjustment, and the starting moment is very large. The most important thing is that the accuracy is high, and there is a linkage interface in the position of the electric box, which can be connected with the control system such as the operating machine, and effectively realize the linkage. Operation.
