Magnetic pipeline cutting machine

Abstract

The invention provides a magnetic pipeline cutting machine, and relates to the field of pipeline cutting. The magnetic pipeline cutting machine comprises a box body, a connecting pipe, a spray head and rotating mechanisms; the connecting pipe communicates with the outer wall of one side of the box body, an air inlet is formed in the connecting pipe, a fixing base is arranged on the outer wall of one side of the box body, a reversing head is arranged on the outer wall of one side of the fixing base, and the spray head is connected with the outer wall of one side of the reversing head; and the rotating mechanisms are connected with the outer wall of the bottom end of the box body, each rolling wheel comprises an inner wheel body, a fixing ring, a buffering mechanism, an elastic piece and an outer wheel body, and a groove is formed in the axis of each inner wheel body. According to the magnetic pipeline cutting machine, the vibration amplitude of the outer wheel bodies passing through protrusions is reduced, so that the spray head is more stable, broken scrap iron clamped in grooves a can be ejected out, uneven vibration generated by the broken scrap iron is reduced, and the problem that when the spray head passes through the uneven outer wall of a pipeline, a cut opening is uneven and has burrs due to vibration are effectively solved.

Description

technical field [0001] The invention relates to the technical field of pipe cutting, in particular to a magnetic pipe cutting machine. Background technique [0002] The magnetic pipe cutting machine is suitable for cutting and bevel cutting of various seamless steel pipes in factories and mines such as petroleum, chemical industry, shipbuilding, power generation machinery construction and installation. The magnetic pipe cutting machine has two sets of four permanent magnetic wheels, which can automatically cut around the steel pipe through the transmission mechanism. The cutting process can use oxy-acetylene flame or oxy-propane flame. It is suitable for cutting and beveling seamless steel pipes of various specifications with a diameter above 108mm. Due to the adsorption force of the magnetic wheel, the cutting machine can also perform full-position multi-directional cutting in various spatial positions of flat, vertical, horizontal, and upward. Cutting and beveling can be ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a magnetic pipe cutting machine, which solves the problem that when the rollers rotate along the outer wall of the pipe to be cut, in order to cut a relatively smooth cut and bevel, it is necessary to first The pipe is smoothed, but due to the oxidation reaction of the outer wall of the pipe in long-term contact with the outside world or the inadequacy of the existing technology, some of the outer wall of the pipe will have uneven cuts, which cannot be completely smooth and flat, resulting in the nozzle being in the cutting process. There will also be unevenness and burrs at the cutting edge due to vibration, which will affect the effect of pipe cutting
