Abstract

PURPOSE: To provide the titled pipe expanding apparatus which makes a large-sized casing subjected to receiving reaction force of jack unnecessary, by carrying out pipe expansion utilizing the mutual approach, that is, mutual pulling force against each other, of a couple of driving parts by the jack for pipe expansion and reasonably treating the internal force by a simple means.
CONSTITUTION: Pressure oil is supplied to the jack for pipe expansion and the rod for driving 24 is moved in a fixed direction placed each shoe for pipe expansion 5 of this pipe expansion apparatus at the reduction position of the figure. As a result of it, the first driving parts 2 and the second driving parts 3, are moved mutually approaching in the axis direction of the steel pipe 4 and also, the inner end parts of the first link 39 and the second link 41, are moved approaching in the axis direction of the pipe 4 by each parts 2, 3 through the inside link support metal fittings 33, 34. Accordingly, the shoe 5 is moved in the pipe expansion direction, that is, radial direction by the outer end part of each link 34, 41.
