Description

Pipeline cutting machine

Technical Field

The invention belongs to the technical field of cutting machines, and relates to a pipeline cutting machine.

Background

Because the displacement pipe is bent and the pipe wall is thin, deformation is easily caused in each cutting process, and the displacement pipe is scrapped. In order to ensure that the used part does not deform during processing and cutting, the waste part of the exhaust pipe is clamped at the three-grab chuck, the chuck is required to be opened back and forth for each clamping, and the clamping is inconvenient. When cutting, the whole exhaust pipe using part falls from the three-jaw chuck after cutting to cause collision, so that the outer surface of the exhaust pipe is easy to be damaged, the three-jaw chuck is required to be opened to take out waste materials, and the waste materials are also troublesome to take out. When cutting, the workpiece rotates, the blade is manually controlled to advance, the waste force is generated during operation, the edge of a knife after cutting is not uniform, burrs are longer, the subsequent processing is not facilitated, and the blade is easy to damage during processing, so that the cost is increased.

Disclosure of Invention

The invention aims at solving the problems in the prior art, and provides a pipeline cutting machine, which aims at solving the technical problems that: the manual labor intensity is reduced through automatic cutting and feeding.

The aim of the invention can be achieved by the following technical scheme:

The utility model provides a pipeline cutting machine, contains the base, is equipped with cutting device and controlling means on the base, its characterized in that, cutting device contains the fixed block, be equipped with the cutter on the fixed block, the cutter outside has inclined plane one, controlling means contains the cover that compresses tightly of cover on locating the fixed block, compresses tightly the cover inboard and has the inclined plane two corresponding with cutter outside inclined plane one, the cutting machine still is equipped with the actuating source that drives the cover motion that compresses tightly.
