Title:
NOVEL PIPE CUTTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/172539
Kind Code:
A1
Abstract:
Disclosed is a pipe cutting machine, comprising a frame (100), a power device (110), a cutting device (140) and at least one transmission shaft (132), wherein the power device (110) and the cutting device (140) are both mounted on the frame (100); the power device (110) can drive the cutting device (140) via the transmission shaft (132); and a one-way bearing (150) is mounted on the transmission shaft (132), so that the transmission shaft (132) can only rotate in one way. With such a structure, the rebound force generated during cutting the pipe will be absorbed by the one-way bearing mounted on the transmission shaft, rather than acting on the cutting device, so that the cutting device will not bear the acting forces in forward and reverse directions simultaneously. With respect to the prior art, the pressure on the cutting device can be greatly reduced, thereby effectively prolonging the service life of the cutting device.
