Abstract

The invention relates to a welding pipe adjustable vertical roll tool comprising a welding torch, large vertical rolls, small vertical rolls, cantilevers and pull rods. The small vertical rolls include the first small vertical roll and the second small vertical roll, the cantilevers include the first cantilever, the second cantilever, the third cantilever and the fourth cantilever, the pull rods include the first pull rod and the second pull rod, two ends of the first small vertical roll are respectively mounted on the first cantilever and the second cantilever, two ends of the second small vertical rod are respectively mounted on the third cantilever and the fourth cantilever, two ends of the first pull rod are respectively mounted on the first cantilever and the third cantilever through screw pairs, two ends of the second pull rod are respectively mounted on the second cantilever and the fourth cantilever through screw pairs, a first roll shaft is arranged on the first cantilever and the second cantilever, a second roll shaft is arranged on the third cantilever and the fourth cantilever, and the first roll shaft and the second roll shaft are mounted on a pipe welding machine through the screw pairs respectively. By the arrangement, mechanical property of welding lines is improved, weld failure caused by subsequent bend machining or flaring machining is reduced, and rejection rate of products is decreased.

Description

technical field [0001] The invention relates to a welded pipe tool, in particular to an adjustable welded pipe vertical roller tool. Background technique [0002] At present, the argon arc welding pipe making machine (welding without wire filling, one-sided welding and two-sided forming), has two to three sets of vertical rollers at the welding place after the coiled material is rolled into a tubular shape to control the pipe seam for easy welding. When the welding torch 1 is placed on the rear side of the vertical roller group, the rebound tensile stress of the pipe wall after welding has an adverse effect on the crystallization of the weld seam. The existing welding vertical roller groups are far away from each other due to structural size restrictions, and it is difficult to Compressive stress is applied when the weld seam is crystallized, so the effect of the existing pipe-making weld seam is not good, and the mechanical properties are low. Contents of the invention ...
