Description

Technical Field

[0001] The invention relates to the technical field of production of diesel engine pipe systems, and in particular to a profiling tool and a profiling method thereof applied to diesel engine pipe systems. Background Art

[0002] The construction cycle of marine diesel engines is getting shorter and shorter, which requires that the production and assembly cycle of related components must also be shortened accordingly. The assembly of diesel engine piping system belongs to the later process. When the large components of the main engine are installed in place, the assembly of diesel engine piping system begins. However, the time left for the assembly of diesel engine piping system is very limited, so the diesel engine piping system is required to have higher production precision.

[0003] The diesel engine piping system is generally assembled from multiple pipe fittings, each of which is made up of a pipe and flanges welded at both ends. The bending direction of the pipe, in line with the requirements of the diesel engine piping system layout, is mostly a three-dimensional structure, and the flange angles at both ends are also diverse, which increases the difficulty of pipe production.

[0004] At present, when producing corresponding pipe fittings, the template flanges are first welded on the platform, that is, the two flanges are placed at the required positions according to the technical drawings, and then welded to the platform through steel plates. The two template flanges are used as positioning references when making pipe fittings. This template method can only produce a single pipe fitting, and the rotation angle and height of the flange cannot be effectively adjusted according to the relevant requirements of the pipe fitting, and the versatility is poor. When it is necessary to produce pipe fittings required by different drawings, the template flanges need to be welded separately, but manpower and material resources are wasted, and the overall accuracy of the produced pipe fittings is low, which brings great inconvenience to the production of diesel engine pipe systems. Summary of the invention

Through this profiling tool, pipe fittings of various specifications can be produced. The profiling tool can effectively adjust the rotation angle and height of the flange according to the relevant requirements of the pipe fitting, and has good versatility. When it is necessary to produce pipe fittings required by different drawings, it is only necessary to adjust the profiling angle, height and opening of the corresponding flange to the required angle and size through the profiling tool, which not only saves manpower and material resources, but also effectively improves the production accuracy of the pipe fittings, bringing great convenience to the production work of the diesel engine piping system.
