Abstract

PURPOSE:To automatically and accurately measure the pressing center of a stem, by detecting the relation between relative positions of a container and a stem by means of two detectors in extruding a pipe by press-hole-expanding a billet, put in the container, by using the stem. CONSTITUTION:A billet having a guide hole, put in a container 1, is extruded and formed into a pipe by press-hole-expanding by using a stem 21 having a mandrel equipped with an expansion nose. At this time, two detecting parts 4 and 4 of distance meters are provided to the container 1, in the direction of intersecting the axial centers of the stem 21 and a container liner at right angles, to detect the relation between the relative positions of the container 1 and stem 21 in the direction of crossing the axial centers of them. The relative distance between them is obtained by passing the detected value through a temp. correction- part 6, equipped with an amplifir 5 and a temp. sensor 7, to compute the center deviations and inclinations of them with the aids of an operating part 8 and a display part 9. Thus the pressing center is measured accurately and continuously.
