welding rollers for sale in China

Huafei CNC is the best welding roller manufacturer in China. Can accept the manufacture of various welding rollers, and provide pipeline automatic welding solutions.

The welding roller refers to the use of the friction between the weldment and the active roller to drive the circular weldment to rotate to complete the welding of the circular weld. The welding speed can be adjusted by the rotation speed of the active roller on the roller. The rollers should always be kept on the same axis so that the workpiece is not easy to deform and slip when rotating. The welding rollers are mainly divided into self-adjusting welding roller, adjustable welding roller, anti-channeling welding roller, walking welding roller, and long-axis welding roller.

The self-adjusting welding roller can automatically adjust the swing angle of the wheelset according to the diameter of the workpiece, and can automatically adjust the center. It is mainly used for the assembly or welding of cylindrical workpieces such as pipes, containers, boilers, and oil tanks. , When the welding power supply is matched, the inner and outer longitudinal seams and inner and outer circumferential seams of the workpiece can be welded.

The adjustable welding roller consists of a driving wheel and a driven wheel. The active roller operation is controlled and driven by two motors. Through the speed-regulating motor and the speed-regulating controller, the variable frequency speed regulation or electromagnetic speed regulation realizes step-less speed change. The rotation speed of the workpiece can be adjusted to 6-60 meters/hour, which can meet the requirements of manual Welding, automatic surfacing, automatic submerged arc welding, and other different welding needs. The adjustable welding roller can adjust the distance between the main and driven rollers through the screw or screw to meet the welding requirements of different specifications.

The principle of anti-movement welding roller holder is the axial movement of the weldment on the roller, and the weldment itself is in a spiral motion. If measures can be taken, the left-hand rotation of the weldment can be changed to right hand or right in time. The rotation is changed to left-handed until the weldment no longer makes a spiral movement. The anti-movement welding roller uses a photoelectric encoder to detect the movement amount of the workpiece, and the system controller controls the lifting of the driven roller. The displacement detection frame is placed on one end of the workpiece, and the detection wheel is pressed on the end face of the workpiece (the end face must be processed). The detection wheel can rotate with the workpiece. When the workpiece moves axially, the detection wheel will follow the workpiece, and the photoelectric coding The detector detects the movement amount and direction of the workpiece, and its signal is input to the system controller for processing. The controller will adjust the lifting stroke, lifting speed, and lifting interval time of the driven roller according to the amount of movement, and control up or down according to the direction of movement. The movement of the workpiece always fluctuates between -1.5mm and +1.5mm, so that the movement of the workpiece is limited to a certain range, which can meet the needs of welding.

long-axis welding roller

The long-axis welding roller is a piece of displacement equipment that uses the friction between the two long-axis rollers and the workpiece to drive the workpiece to rotate. It is suitable for the spot welding of thin-walled, small-diameter, multi-tube weldments and circumferential seams. The rollers are arranged along two parallel shafts, one row connected with the driving device is the driving roller, and the other row is the driven roller.
