Abstract
The invention discloses a thin-wall pipe cutting system and relates to the technical field of cutting. A pipe locating device of the thin-wall pipe cutting system comprises at least three air cylinders. Locating rods are driven by piston rods of the air cylinders to move so that a pipe can be clamped. When pressure sensors on the locating rods detect that a pressure value reaches a preset valve, the piston rods of the air cylinders stop moving, and therefore the pipe is located. Due to the fact that the multiple air cylinders for localization work independently and the locating pressure is controllable, even though the shape of the outer wall of the pipe is not regular, the pipe wall can not be damaged, and the thin-wall pipe is accurately located. Multiple trapezoidal grooves and reversed trapezoidal grooves are formed in the outer circumference of an installation hole of a cutter head of a cutter and distributed alternately, by the adoption of the arrangement mode, vibration of the cutter in the cutting process can be effectively reduced, and the cutting accuracy is guaranteed. Multiple heat dissipating holes for heat dissipation are further formed in the cutter head, so that the cutter head is not prone to deformation and the service life of the cutter head is effectively prolonged.
