The welding roller frame has a self-adjusting welding roller frame, an adjustable welding roller frame, and an anti-smashing welding roller frame.
Self-adjusting welding roller frame: It is a displacement device that uses the friction between the active roller and the weldment to drive the workpiece to rotate. The welding positioner can automatically adjust the swing angle of the wheel set according to the diameter of the workpiece, and can automatically adjust the heart. When matching, it can realize the inner and outer longitudinal joints of the workpiece and the inner and outer circumferential seam welding. Luoyang Bota Heavy Industry This product is widely used in wind power, pressure vessel, petrochemical, pipeline, steel structure, boiler, shipbuilding, surfacing repair and other industries.
Adjustable welding roller frame: consists of one active and one passive. The driving of the active roller is driven by two motors respectively. Through the speed regulating motor, the speed controller realizes stepless speed change through frequency conversion speed regulation or electromagnetic speed regulation. The linear speed of the workpiece rotation is 6-60 m / h, which can meet the needs of various welding such as manual welding, automatic surfacing, automatic submerged arc welding, and various riveting of the workpiece. The roller spacing can be adjusted by the screw or the splitting gear to meet the welding requirements of different specifications of the workpiece.
Anti-smashing welding roller frame: On the basis of the adjustable roller frame, the roller of the driven frame is made to be liftable, the photoelectric encoder is used to detect the amount of movement of the workpiece, and the system controller controls the lifting of the driven roller. The displacement detecting frame is placed at one end of the workpiece, the detecting wheel is pressed on the end surface of the workpiece (the end surface must be processed), the detecting wheel can rotate with the workpiece, and when the workpiece moves axially, the detecting wheel will follow the workpiece, photoelectric coding The device detects the amount of turbulence and the direction of the workpiece, and its signal is input to the system controller for processing. The controller adjusts the lifting stroke, lifting speed and lifting interval of the driven roller according to the amount of the swaying amount, and controls the raising or lowering according to the swaying direction. The turbulence of the workpiece always fluctuates between -1.5mm and +1.5mm, so that the turbulence of the workpiece is limited to a certain range, which can meet the needs of welding.
