A steel pipe rounding and butt joint tooling

Abstract

The invention discloses a steel tube roundness correcting and butt joint tool. The steel tube roundness correcting and butt joint tool comprises first half rings, second half rings, ear plates and a locking piece, the two ends of the first half rings and the two ends of the second half rings are connected with the ear plates, and the ear plates are bent outwards, and the first half rings and the second half rings are both matched with the outer wall of the steel tube; and first strip-shaped holes and second strip-shaped holes are formed in the first half rings and the second half rings correspondingly, the length directions of the first strip-shaped holes and the length directions of the second strip-shaped holes are perpendicular to the axial direction of the steel tube, and the first half rings and the second half rings are connected and locked through locking pieces arranged on the ear plates. The tool is connected with a deformed steel tube port through the first half rings and thesecond half rings in a locked mode, and a deformed steel tube port can be forcibly restored to be round; the tool is simple in structure, convenience and fast are achieved, the problem that the two opposite butt jointing pipes are located at the same center can be solved, the problem of the steel pipe port deformation can be solved as well, the problems of pipe port deformation and pipe centeringare solved very effectively, the tool is convenient to use by field workers, and the utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe assembly tooling, in particular to a steel tube rounding and docking tooling. Background technique [0002] During the shipbuilding construction process, a large amount of stainless steel construction is involved, but on site, large-diameter steel pipes generally suffer from deformation problems and the problem that the alignment and gap between steel pipes cannot be guaranteed. During the first construction, it took a worker one day to assemble a piece of 325 stainless steel. It was difficult to guarantee the efficiency and quality, and the pass rate of the calibration was low. How to ensure the assembly quality and efficiency of the two joints was an important factor in the construction process.

Problems solved by technology

[0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a steel pipe rounding, convenient and fast, which can not only solve the problem of the same center position of the two butt joint nozzles, but also solve the deformation problem of the steel pipe nozzles. Butt tooling

When the problem of concentricity cannot be guaranteed due to the deformation of the pipe, this tool is used to fit the first half ring and the second half ring to the deformed steel pipe mouth, and adjust the gap between the butt pipes so that the gap between the butt pipes is in the shape of a bar. The position of the hole is tightened by the locking piece, and the deformed steel pipe mouth can be forced to return to a circular shape, and then the butt pipe is fixed by spot welding at the position of the strip hole
