Document Type and Number:
Japanese Patent JP2019171439
Kind Code:
A
Abstract:
To provide a pipe end machining device that can reduce friction force at the time of machining and further enhance a degree of freedom of a folding-back angle of a pipe end.SOLUTION: A pipe end machining device 100 comprises: a rotationally driving source 12 that rotationally drives a base 12; a shaft 13 fixed to a tip part of a base 11; a slide base 17 that can slide along an axis of the shaft 13; a roller guide member 18 fixed to the slide base 17; a slide base driving member 20 that converts rotational movement of the base 11 to straight movement and slidably drives the slide base 17 together with the roller guide member 18; and a roller 21 that is pressed against an inner surface of a pipe end to fold the pipe end outward in a pipe diameter direction.SELECTED DRAWING: Figure 1
