Automatic welding machine for round pipe heat preservation nail

Abstract

The invention discloses an automatic welding machine for a round pipe heat preservation nail. The automatic welding machine comprises a rack, wherein a heat preservation nail welding machine assemblyand a clamping mechanism are arranged on the rack, the clamping mechanism is used for clamping a to-be-welded pipefitting, the heat preservation nail welding machine assembly is used for welding the heat preservation nail on the to-be-welded pipefitting, and a welding gun of the heat preservation nail welding machine assembly is perpendicular to the axis of the to-be-welded pipefitting. The preservation nail is welded by using the automatic welding machine. The to-be-welded pipefitting is fixed by the clamping mechanism, and the heat preservation nail is welded by the heat preservation nail welding machine assembly without holding the welding machine manually, so that the problem that the heat preservation nail inclines is avoided. Furthermore, the welding gun of the heat preservation nailwelding machine assembly is arranged perpendicular to the axis of the to-be-welded pipefitting, so that the problem that the welding position of the heat preservation nail is inaccurate as a lineation position is inaccurate is avoided. The automatic welding machine reduces the manual operations greatly and guarantees the accurate welding position. The heat preservation nails are uniform in welding parameter and good in quality. The automatic welding machine is high in welding speed and improves the production efficiency and the production quality.

AI Technical Summary

Problems solved by technology

The most commonly used and very effective and simple method for pipeline insulation is to weld the insulation nails on the surface of the pipeline and then wrap the insulation layer. Use insulation nails to prevent deformation and displacement of the insulation layer. The welding of insulation nails is basically carried out by workers with hand-held stud welding machines. For the welding method, it is necessary to draw a line on the pipe to determine the position of the welding stud before welding. Since the pipe is an arc-shaped round surface, it is difficult to ensure the accurate position by simple manual marking. The direction is often tilted. At the same time, the pressure and arc striking time of manual stud welding cannot be accurately consistent due to human operation. Manual welding often causes burns and other accidents.
