Title:
PIPE CUTTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/052069
Kind Code:
A1
Abstract:
[Problem] To provide a pipe cutting machine, which is capable of efficiently cutting even large diameter pipes in a short time, the structure of which is simple, small, lightweight and economical, and which has excellent durability. [Solution] A pipe cutting machine for cutting a pipe 10 at a right angle to the center line thereof is provided with: a pair of rotating saw blades 20, 20 disposed, when a plane at a right angle to the center line of the pipe 10 to be cut is the x-y plane and the center of the pipe 10 is the origin of the coordinates, opposite each other on the two sides of the y-axis so that the tool edges overlap in the x-axis direction; a rectilinear drive mechanism 50 for rectilinearly driving the pair of rotating saw blades 20, 20 in opposite directions in the y-axis direction so that the pair of rotating saw blades 20, 20 pass by each other on and near the x-axis; and motive power direction-changing mechanisms 46 and 47 for moving the pair of rotating saw blades 20, 20 outward from the y-axis by changing a portion of the rectilinear driving force in the y-axis direction to the x-axis direction in order to avoid interference of the tool edges when the pair of rotating saw blades 20, 20 pass each other on and near the x-axis.
