An automatic welding machine for round pipe insulation nails

Abstract

The invention discloses an automatic welding machine for heat preservation nails for round pipes, which includes a frame, on which a heat preservation nail welding machine assembly and a clamping mechanism are arranged, and the clamping mechanism is used to clamp pipe pieces to be welded. The heat preservation nail welding machine assembly is used for welding heat preservation nails on the pipe to be welded, and the welding torch of the heat preservation nail welding machine assembly is perpendicular to the axis of the pipe to be welded. The heat preservation nail welding is carried out by adopting the present invention, the pipe fittings to be welded are fixed with a clamping mechanism, and the heat preservation nail welding is carried out through the heat preservation nail welding machine assembly, without the need for workers to hold the welding machine, avoiding the problem of inclination of heat preservation nails, and the heat preservation nail welding machine assembly The welding torch is set perpendicular to the axis of the pipe fittings to be welded, which avoids the problem of inaccurate welding positions of heat preservation nails caused by inaccurate marking positions. The invention greatly reduces manual operations, ensures accurate welding positions, and uniform welding parameters of each heat preservation nail. The quality is good, and the welding speed is fast, which improves the production efficiency and 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.
