Abstract

PURPOSE: To prevent a chattering phenomenon and improve the operation efficiency of a sawing machine for cutting off a long pipe or the like, by providing two rotary clamps at both the sides of the cutting-off line of the machine, directly coupling the clamps to each other and synchronously driving them.
CONSTITUTION: A pipe 34 to be cut off is conveyed in so that it is located on an auxiliary rotary clamp 10 and a main rotary clamp 12. After the pipe 34 is adjusted for a cut-off length, hydraulic cylinders 28, 29 provided in the clamps 10, 12 are operated to clamp the pipe. After that, saws 15 driven by a motor 16 are operated by a cutting-in means 18 so that the saws cut into the pipe 34 in three directions different by 120° from each other. When the saws 15 have cut through the wall of the pipe 34, the pipe is rotated by a transmission means 23 so that the pipe is completely cut off. At that time, the pipe 34 is supported at both its ends on conveyor rollers and held by the clamps 10, 12 at both the sides of the saws 15 and synchronously rotated through direct connection. For that reason, the pipe 34 is cut off without causing a chattering phenomenon.
