Description
Technical Field
The utility model relates to the technical field of steel pipe rounding, in particular to a large-caliber steel pipe duplex intelligent rounding device.
Background
In the field of industrial manufacturing or construction engineering of large chemical containers, large conveying pipelines, bridge steel pipe arches or steel pipe lattice pier columns and the like, large-caliber steel pipe structures are often used. Because the steel plate width and the pipe coiling equipment capacity are limited, the single pipe manufacturing cannot be too long, and the length of the single pipe cannot meet the actual requirements, the single pipe can only be formed by adopting a mode shown in fig. 1 and adopting a plurality of single pipe assembly welding.
The conventional production flow of large-caliber steel pipe splicing is as follows: steel plate blanking, steel plate coiling, steel pipe longitudinal seam welding, steel pipe rounding, steel pipe pairing assembly and pairing girth welding. After welding the longitudinal seam of the rolled short steel pipe, the rolled short steel pipe is subjected to re-rounding through a plate bending machine, but ovality and diameter deviation still exist. Therefore, when two short steel pipes are assembled in a butt joint way, due to the problems of ovality and diameter deviation of the steel pipes, local misalignment or ovality of adjacent pipe orifices of the two steel pipes is out of tolerance, and the welding quality or geometric dimension of a butt joint weld joint is unqualified due to the misalignment of larger deviation, so that a large amount of repair treatment work is brought.
In the prior art, when the steel pipes are assembled in a pairing way, the circumferential offset and ellipticity of adjacent ports between the steel pipes are required to be controlled within a reasonable tolerance range. The common practice is to carry out matching measurement on adjacent pipe orifices of the steel pipes, radially press the lower part or the part with the ovality exceeding the standard by using a manual jack in the part with larger misalignment, enable the lower part or the part to be flush with the inner surface and the outer surface of the adjacent steel pipes or have the ovality, then carry out section welding and fixing, and fix the temporary support replacing jack in the corresponding part in the pipe. And similarly, the overlapping and ellipticity of the whole circumference are adjusted and matched, and the working procedures of steel pipe assembly butt joint and girth welding are completed.
Therefore, the traditional pairing matching method is operated manually and is carried out through the cooperation of tools such as a jack, a temporary support and a measuring instrument, the workload is huge, the working efficiency is very low, and the pairing precision is often not satisfactory and needs to be reworked, so that the problem is needed to be solved.
