Claims

[Scope of utility model registration request]

A laser oscillator and a laser receiver are arranged to face each other in the diameter direction of the tube to be cut, a cutting torch is provided on a line connecting the laser oscillator and the laser receiver, and is located approximately at the center of the pipe, and the laser receiver is used for detection. and a drive system that moves the cutting torch up and down depending on whether or not a laser beam generated from the laser oscillator can pass through, and maintains a constant distance between the tip of the cutting torch and the cut portion on the surface of the pipe to be cut. A profiling device for a pipe cutting crosspiece, which is characterized by:
