Title:
TUBE CLAMP DEVICE OF TRAVELLING CUTTING MACHINE
Document Type and Number:
Japanese Patent JP3831106
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To clam and unclamp a pipe even in a case where the pipe shape is different like a circular tube or an angular tube without exchanging a clamp piece, and to perform a travelling cut work efficiently and safely.
SOLUTION: A clamp piece 15 installed on a pressurizing mechanism 14 is formed with a shoe 27 for a circular pipe and a shoe 28 for an angular pipe, and one of the shoe 27 for the circular pipe or the shoe 28 for the angular pipe is projected selectively by a shoe switching means 35 according to a shape of a pipe 11 formed, so that the clamping face thereof is allowed to abut with a peripheral face of the pipe 11. Therefore, although a pipe shape is different, the pipe 11 is clamped surely by the same pressurizing mechanism 14 in travelling cut without changing the clamp piece 15.
