[0002] Welded steel pipe refers to a steel pipe with seams on the surface that is formed by bending steel strips or steel plates into round, square and other shapes and then welding them. Welded steel pipes have lower costs and higher production efficiency than seamless steel pipes. The blanks used are steel plates or strips. Welded steel pipes have strong corrosion resistance in acidic environments. Among them, straight seam welded pipes are characterized by simple production process, high production efficiency and low cost.
[0003] In the production process of seam welded pipes, the uncoiled steel strip needs to be pre-bent by a forming machine. After passing through multiple forming frames, the steel strip is curled into a "C shape" and finally curled into an "O shape". However, during the pre-bending process, due to the improper adjustment of the seam pressure roller, the welding equipment cannot be correctly aligned with the open seam, and the misalignment of the steel strip welding is large, resulting in empty welds in the open seam of the pipe blank after welding, and the welded pipe is not completely closed.

[0009] As a preferred solution of the utility model, the bottom ends of the oblique sides of the linkage rods are rotatably connected to the second round rods, and the bottom ends of the brackets are fixedly connected to the base.
[0010] Compared with the prior art, the beneficial effect of the straight seam welded pipe forming misalignment correction device of the utility model is: the utility model supports and squeezes the two sides of the steel pipe through two clamping rings, so that the unclosed position of the top end of the steel pipe moves toward the middle at the same time, and the two pressure rings squeeze the unclosed position of the top end of the steel pipe, so that the unclosed position of the steel pipe moves toward the middle along the bottom wall of the pressure ring at the same time, and finally the unclosed position of the steel pipe is connected together, thereby playing the role of misalignment correction and preventing the problem of empty welding in seamless steel pipes, and the utility model is relatively strong.
