CNC machine tool for processing metal pipe fittings

Abstract

The invention provides a numerically controlled machine tool for processing metal pipes. The numerically controlled machine tool comprises a box body module, fixed devices, a steel pipe and a sprayingdevice. The invention can solve the problems that the spraying efficiency is low as the ranges of spray heads cannot be adjusted according to the diameters of large-diameter metal pipes with different diameters by existing spraying equipment in the current spraying process; meanwhile, as the diameters of the pipelines are inconsistent during spraying, the distances between the spray heads and thepipes are varied, the spraying strength is not uniform, a spraying agent cannot spray on the outer walls of the pipelines and further the spraying efficiency is affected; and in addition, a large amount of particulate matters are produced in the spraying process and are not attached to the outer walls of the pipes, so that the particulate matters disperse in air to influence the working environment of a workshop, or even body health of workers is affected in a serious situation, and the like.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a numerically controlled machine tool for processing metal pipe fittings. Background technique [0002] For some metal transportation pipelines, they are often buried in the ground when they are in use. The outer wall of the pipeline usually needs to be treated with anti-rust and anti-corrosion treatment. Protective layers such as spraying preservatives are adopted for its outer wall; but the existing spraying mainly has the following problems: [0003] 1. For large-diameter metal pipes with different diameters; the existing spraying equipment cannot adjust the nozzle range of the nozzle according to the diameter of the pipe fittings, resulting in low spraying efficiency. The intensity of the spraying is uneven, so that the spraying agent cannot be sprayed to the outer wall of the pipe fitting; it affects the spraying efficiency; [0004] 2. During the spraying ...

AI Technical Summary

Problems solved by technology

[0006] The present invention can be used for large-diameter metal pipes with different diameters in the existing spraying process; the existing spraying equipment cannot adjust the nozzle range of the nozzle according to the diameter of the pipe fittings, resulting in low spraying efficiency, and at the same time, due to the different diameters of the pipes during spraying, the nozzles are different from each other. The distance between the pipe fittings is not uniform, resulting in uneven spraying force, so that the spraying agent cannot be sprayed on the outer wall of the pipe fittings; it affects the spraying efficiency; and a large number of particles generated during the spraying process are not attached to the outer wall of the pipe fittings, resulting in dispersion in the air and affecting the work of the workshop environment; in severe cases, it will affect the health of workers and other issues
