Abstract

PURPOSE:To manufacture the tubular body with highly accurate inside/outside diameters and with a polygonal head, by forming as follows; a through-hole is pierced in the metal blank, the mandrel is inserted into this through-hole, and the ironing work is applied to this metal blank so as to form a large head, and then, this head is formed into a polygon.
