Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting machines, in particular to a steel pipe cutting machine. Background Art

[0002] The principle of the pipe cutting machine is that the air-oil pushes each other, and the electrical system controls the movement direction of the air pressure system, pushing the oil circuit to make a straight reciprocating motion. During the reciprocating motion, the signal detected from the drag plate limit is used as a basis to control and change the movement of the air and oil circuits, so as to achieve the expected cutting path. The pipe cutting machine greatly improves and alleviates installation safety and fire safety, and has precise cutting. After cutting, both sides of the pipe are flat, which is easy to connect. The cutting method is simple and fast, saving a lot of working time. It can provide a light working method and can design the cutting plan according to the workplace (on-site).

[0003] Steel pipe cutting machines are commonly used equipment in the mechanical field. Currently, many pipe cutting machines have complex structures. In order to put large steel pipes into the pipe cutting machines, the pipe cutting machines are large in size and cannot be carried lightly. In addition, the wall thickness of the cut pipes is different, and the cutting blades in the pipe cutting machines are not convenient for cutting the steel pipes. Utility Model Content
