Automatic cutting process for steel structure pipe fittings

Abstract

The invention relates to an automatic cutting process for steel structure pipe fittings, and the process is mainly completed through the cooperation of an automatic cutting machine for the steel structure pipe fittings. The automatic cutting machine for the steel structure pipe fittings comprises a mounting frame, a pre-cutting sleeve piece and a punching sleeve piece, and the pre-cutting sleeve piece and the punching sleeve piece are sequentially arranged on the mounting frame from bottom to top. The automatic cutting process for the steel structure pipe fittings solve the problems that a, when an existing steel structure pipe fitting is subjected to cutting operation, the circumference of a super-tangent plane is often deformed when an existing steel pipe is cut, burrs appear on the cutplane, and then secondary machining needs to be conducted on the cut steel pipe in order to meet the use requirement, and therefore the workload of workers is greatly increased; and b, when the existing steel pipe is subjected to vertical cutting, the situation that the cutting position is not completely cut off often occurs, cutting needs to be conducted multiple times later, the production progress is greatly slowed down, and time is wasted.

Description

technical field [0001] The invention relates to the technical field of steel structure pipe fittings, in particular to an automatic cutting process for steel structure pipe fittings. Background technique [0002] A steel pipe is a steel with a hollow section whose length is much greater than its diameter or circumference. Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. Frames, pillars and mechanical supports can reduce weight and save 20-40% of metal, and can realize factory-like mechanized construction. Manufacturing highway bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area coated with protective layers and save energy. Investment and maintenance costs. When the existing steel structure pipe fittings are used in bridges, in order to meet the needs of use, it is often necessary to cut additional through holes on the pipe fittings to...

AI Technical Summary

Problems solved by technology

[0003] Existing steel structure pipe fittings often have the following problems when cutting operations: a: Existing steel pipes often cause deformation of the circumference of the super-cut surface when cutting, and burrs appear on the cutting surface, and often need to be repaired to meet the use requirements afterwards. The cut steel pipe is subjected to secondary processing, which greatly increases the workload of the employees b: when the existing steel pipe is cut vertically, the cutting part is often not completely cut off, and multiple cuts are required later , which greatly slows down the production schedule and wastes time
