Pipe cutting device

Abstract

The invention discloses a pipe cutting device. The pipe cutting device comprises an upper machining base and a lower machining base, wherein the lower machining base is provided with a cutting module with a first through hole, a first inner support pipe with magnetism, and a magnetic body for adjusting axial position of the first inner support pipe; the upper machining base is provided with a punch bonded with the cutting module and provided with a second through hole, and an elastic ejector rod for pushing a second inner support pipe; and during cutting, the first inner support pipe and the second inner support pipe are respectively positioned on two sides of a cutting port. During cutting by the pipe cutting device, as the inner support pipes are arranged in a pipe, and the two inner support pipes are respectively positioned on two sides of the cutting port, when the punch downwards moves to cut off the pipe, the deformation of the cutting port of the pipe is lower, and the yield of the pipe is improved; and when the punch is acted on the pipe, the pipe is cut off mainly through shearing force, so that the pipe material wear and loss can be reduced, and the pipe material utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of cutting, and more specifically, relates to a pipe cutting device. Background technique [0002] Copper tubes are widely used in many fields, especially in secondary wiring. When producing copper tubes, cutting the copper tubes is a very important and necessary step. After the cutting operation, the copper tubes whose length meets the production requirements can be obtained. [0003] When cutting the existing copper pipes, it is mainly to directly cut the hollow copper pipes. You only need to move the copper pipes to the cutting position, and then you can use the sawtooth to cut the copper pipes. When cutting, because the copper pipes are hollow, so It is easy to produce a large amount of deformation, which affects the forming rate of the copper pipe; and the saw teeth are prone to loss during the sawing process, resulting in waste of copper pipe material. [0004] To sum up, how to provide a pipe fittin...
