Problems solved by technology

Existing steel pipe cutting machines usually cut from the outside of the steel pipe. This operation requires the thickness of the cutting piece to be greater than the diameter of the steel pipe or to rotate the steel pipe for cutting. The cutting debris splashes heavily, and the burrs are mostly located on the inner surface, which is not easy to polish

Abstract

The invention discloses a building steel pipe cutting device, and belongs to the technical field of building cutting machinery. The building steel pipe cutting device aims to solve the problems that an existing steel pipe cutting machine usually cuts from the outside of the steel pipe, the operation requires that the thickness of a cutting sheet is larger than the diameter of the steel pipe or thesteel pipe is rotated for cutting, so that chippings are seriously splashed, and burrs are mostly located on the inner side surface and are not easy to polish. The technical key points of the building steel pipe cutting device are characterized by comprising a cutting machine tool, a feeding base, a first positioning base, a second positioning base, a mounting frame and the cutting sheet; the feeding base, the first positioning base, the second positioning base and the mounting frame are sequentially arranged on the cutting machine tool along the same axis, and the cutting sheet with the diameter smaller than that of the steel pipe is arranged on the mounting frame; and a cutting motor drives the cutting sheet to rotate at a high speed, the cutting sheet is also driven by an eccentric wheel to cut the steel pipe from inside to outside, so that splashing of the chippings is effectively inhibited, moreover, the burrs of the cut steel pipe are mostly located on the outer side surface, and therefore the later grinding operation of a steel pipe cut can be more easily carried out.

Description

technical field [0001] The invention relates to the technical field of building cutting machinery, in particular to a cutting device for building steel pipes. Background technique [0002] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save metal by 20-40%, and realize factory-like mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. Especially in building construction, it has been widely used. [0003] The steel pipe cutting machine is used for cutting steel pipes, and the existing steel pipe cutting machines are generally by placing the steel pipes on the cutting table, and then c...
