Problems solved by technology

Usually, after the steel plate or strip is bent and welded, the weld seam of the steel pipe must be processed to make the weld seam position smooth and the structure regular. For the welding connection between different steel pipes, it is To ensure the smoothness and regular structure of the weld position, post-processing of the weld position is also required. During the processing, the existing leveling device cannot meet the processing requirements of high precision and high efficiency

Abstract

The invention belongs to the technical field of steel pipe machining, and particularly relates to a welding seam leveling device of steel pipe welding. The leveling device comprises a rack, a first worktable and a second worktable, wherein the first worktable and the second worktable are arranged on the rack, and the second worktable is located above the first worktable; the leveling device further comprises a first driving motor, a second driving motor and a mounting frame, wherein an output shaft of the first driving motor is connected with an expansion rod, and the output shaft of the second driving motor is connected with a screw rod; and a pressing roller and a nut are installed on the mounting frame, the nut is matched with the screw rod and is driven by the second driving motor, thepressing roller close to or away from the expansion rod, and the welding seam of a steel pipe sleeving the expansion rod is subjected to leveling treatment when the pressing roller is close to the expansion rod. According to the welding seam leveling device, the supporting and bearing are carried out from the inside of a pipe core, a steel pipe is rotated, and is matched and extruded with the pressing roller to achieve the leveling of the position of the welding seam, and the leveling efficiency of the welding seam is improved.

Description

technical field [0001] The invention belongs to the technical field of steel pipe processing, and in particular relates to a weld seam leveling device for steel pipe welding. Background technique [0002] Welded steel pipe refers to a steel pipe with welded seams on the surface that is welded after bending and deforming a steel strip or steel plate into a circular or square shape. The blank used for the welded steel pipe is steel plate or strip steel. Usually, after the steel plate or strip is bent and welded, the weld seam of the steel pipe must be processed to make the weld seam position smooth and the structure regular. For the welding connection between different steel pipes, it is To ensure the smoothness and regular structure of the weld position, post-processing of the weld position is also required. During the processing, the existing leveling device cannot meet the processing requirements of high precision and high efficiency. Contents of the invention [0003] T...
