During the operation of the welding turning roll, the transmission device drives the active roller, and the friction between the driving roller and the cylindrical workpiece is used to drive the workpiece to realize the displacement during use, and the inner and outer annular seams of the workpiece and the inner and outer parts can be realized. The horizontal position of the longitudinal seam is welded, and the automatic welding equipment can be used for automatic welding.
Welding roller frame application
The welding roller frame is mainly used for cylindrical assembly and welding. If the heights of the main and driven rollers are properly adjusted, the assembly and welding of the vertebral bodies and the segments can also be performed. For some non-circular long weldments, if they are installed in a special annular clamp, the welding work can also be carried out on the welding roller frame. The welding roller frame can also be used with manual welding as a device for detecting and assembling cylindrical workpieces. The use of the welding roller frame can greatly improve the quality of the weld, reduce the labor intensity and improve the work efficiency.
The adaptive control of the welding roller frame has the ability to modify its own characteristic parameters to accommodate changes in the dynamic characteristics of the controlled object and the disturbance. In adaptive systems, the algorithm we use is the "parameter tracking algorithm." That is, the computer automatically tracks and presets the threshold of the sent signal, and these parameters are not fixed during the control process. To put it bluntly, let the computer remember the shape of the end face of the weldment and then distinguish the true amount of turbulence. In this way, the problem is simple, as long as the control of the momentum is controlled and the end face error is ignored.
