Thin-wall pipeline cutting device

Abstract

The invention provides a thin-wall pipeline cutting device which comprises a bidirectional driving assembly, clamping and cutting assemblies and a steel wire saw blade, two execution components of the bidirectional driving assembly are each provided with one clamping and cutting assembly, and each clamping and cutting assembly comprises a linear guide rail I, a supporting frame, a V-shaped clamping part, a motor I, a stepped shaft, a one-way bearing, a gear, a winding wheel and a rack. The two ends of the steel wire saw blade are wound around the winding wheels in the two clamping and cutting assemblies correspondingly. The thin-wall pipeline is rubbed in a reciprocating mode through the steel wire saw blade moving in a reciprocating mode, then the effect of friction cutting of the thin-wall pipeline is achieved, the supporting frame moves downwards through the one-way bearing II, the gear and the rack when the steel wire saw blade moves in a reciprocating mode, and then the steel wire saw blade moves downwards along the cylindrical face of the thin-wall pipeline to achieve cutting. And the U-shaped open cutting device can cut the pipeline at a fixed position, so that the cutting device can adapt to various cutting working conditions.

Description

technical field [0001] The invention relates to the technical field of pipe cutting, in particular to a thin-wall pipe cutting device. Background technique [0002] Publication No. CN112705785A provides a fully automatic cold cutting device for pipe cutting, including a guide mechanism and a frame, on which a crawling mechanism, a cutting mechanism and a cooling mechanism are installed, and a hydraulic control system is connected; the crawling The mechanism includes a walking hydraulic motor, a gear reducer, a chain tensioning assembly and a sprocket transmission assembly, and the frame is fixed on the pipeline to be cut through a toothed chain; the cutting mechanism includes a cutting hydraulic motor, a worm gear reducer and a cutting knife The side of the worm gear reducer is equipped with a screw elevator for adjusting the up and down movement of the cutting mechanism; the cooling mechanism uses a flow control valve, a cooling liquid delivery pipeline, a universal nozzle ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned prior art also cuts the pipeline by being clamped on the pipeline, but after the above-mentioned cutting device is clamped on the pipeline, the whole device needs to move along the toothed chain and the track, so when the device is matched with the pipeline, it is also necessary to move the The device cooperates with the toothed chain, which makes it difficult to operate
