Description

Spiral pipe welder with adjustable pipe diameter Technical Field The utility model relates to a pipe diameter adjustable spiral pipe welder, in particular to a pipe diameter adjustable spiral pipe welder, and belongs to the technical field of spiral pipe welders. Background The spiral pipe welder is used for manufacturing spiral seam welded pipes, steel pipes with different diameters can be produced by using strip steel with the same width, steel pipes with the same diameter can be produced by using strip steel with different widths, and the spiral pipe welder meets the production requirements of large-caliber steel pipes through flexible forming, efficient welding and intelligent detection technologies and is a key device in industries such as petroleum, chemical industry and the like. The device drives the first screw rod to rotate through the first motor in the Chinese patent application publication CN222059228U, so that the first sliding block moves up and down along the first sliding groove, the first collecting box is driven to move inside the pipeline through the movement of the first sliding block, the fan is started when welding is carried out, smoke dust generated during welding inside the pipeline is sucked from the first collecting box, and the smoke dust is discharged after being purified in the filtering box, so that the influence on workers is reduced. However, in the technical scheme of the patent, the pipe diameter of the steel pipe welded by the spiral pipe welder is inconvenient to adjust, the existing spiral pipe welder is used for welding after the strip steel is spirally formed into the steel pipe by conveying the strip steel, and the spiral of the strip steel is realized by the cylindrical forming guide frame, so that the pipe diameter of the steel pipe is determined by the diameter of the cylindrical forming guide frame, when steel pipes with different pipe diameters are required to be welded, the forming guide frame needs to be replaced, more forming guide frames with different diameters need to be prepared for standby, and the mode of adjusting the pipe diameter of the steel pipe by replacing the forming guide frame is also inconvenient.
