Introduction to the technical development requirements when the roller frame is operated

1. The roller frame automatically adjusts the swing angle of the wheel group according to the diameter of the workpiece, and can automatically adjust the center. When matched with the welding manipulator and welding power supply, it can complete the welding of the inner and outer longitudinal seams and inner and outer circular seams of the workpiece. The special welding auxiliary equipment for the positioner is suitable for the welding displacement of the reverse operation, so as to obtain the ideal processing position and welding speed. The roller stand is a device that drives the cylindrical (or conical) weldment to rotate by virtue of the friction between the weldment and the automatic roller. The welding manipulator is generally composed of columns, beams, reversing mechanisms, trolleys and other components. A device that sends the welding head or welding torch to and maintains the position to be welded, or moves the flux along a prescribed track at a selected welding speed.
2. The noise of the transmission system is low, and the reverse movement of the workpiece is stable. It can complete the construction operations of welding, polishing, rubber lining and installation of a cylindrical cylinder. The speed of the roller control should be stable and uniform. Creeping education is not allowed.
3. There must be overvoltage protection, self-management and maintenance system functions, and fault data display and storage service functions, automatic control of air switch short circuit protection, and preset parameters.
4. The height of the main drum and the driven drum can be adjusted appropriately, and the installation and welding of the cone and segmented unequal diameter inverting body can be carried out.
5. For some non-circular long weldments, use a special ring clamp to clamp, or perform installation and welding operations on a welding wheel frame.
6. The speed of the rollers of the self-adjusting roller frame can adopt China's digital economy adjustment and display information technology. The setting of the welding speed is very intuitive and accurate, which reduces the difficulty of operation and management for workers. The manufacturing and installation accuracy of the roller frame should meet the standard 8-level accuracy requirements. The drum frame should be made of high-quality steel. If a welded structure base is selected, stress relief heat treatment should be carried out after welding.
8. The roller frame must be equipped with reliable conductive equipment, and the welding current is not allowed to flow through the bearing of the roller frame.
9. When the cylindrical workpiece is welded on the anti-axial movement roller structure frame, the axial movement of the workpiece should be ≤ ± 3mm during the welding operation of the whole system. 10. The center distance of each pair of rollers of the roller frame must be adjusted according to the diameter of the cylindrical workpiece, so as to ensure that the wrapping angle of the two rollers to the simplified body is greater than 45° and less than 110°. Kill well. Equipped with a 15-meter control cable, drum reversing switch, close-range control, and remote control switch. The rollers are made of polyurethane or neoprene.
