High-speed high-stability high-frequency straight seam pipe unit

Abstract

The present application relates to the technical field of straight seam welding, and particularly relates to a high-speed high-stability high-frequency straight seam pipe welding unit, which comprises a supporting base, the back end of the supporting base is fixedly connected with a back supporting frame, the top of the back supporting frame is fixedly connected with a supporting plate, the bottom of the supporting plate is provided with a straight seam welding unit, and the top of the straight seam welding unit is slidably connected with the bottom of the supporting plate through sliding rails; a speed cooling nozzle is connected with the straight seam welding unit through a mounting plate and slides synchronously, the cooling device follows the movement of the weld for cooling, the arc of the arc-shaped frame or the position of the arc-shaped frame is quickly adjusted, the welding joint ensures that the straight seam welding unit is always aligned with the weld, the inner supporting mechanism is arranged to support from inside to outside, the welding station is further supported and fixed, deformation is prevented, welding stability is improved, the high thermal conductivity of copper is utilized, the effect of auxiliary heat dissipation is achieved, the temperature rise inside the pipe is further reduced, and the pipe is prevented from overheating.
