Abstract
PURPOSE:To mass-produce formed articles at a small pressing pressure and with a high accuracy by providing an unrestrained part longer than the length in the axial direction of an article to be ironed between a 1st ironing die and the inside ironing part of a 2nd ironing die following the 1st ironing die. CONSTITUTION:In an inside part of a guide spacer 45 is provided an unrestrained part P which does not restrain a stock of the article to be ironed in its thickness direction over the range longer than the length L2 of the article to be ironed 22. In ironing, a rounded article 22 is placed inside a guide 43, then, a punch 23 falls and the rounded article 22 is fitted on the external circumference of the punch, pushed by a stopper part 48 and ironed by an inside ironing part 44a of the 1st ironing die 44 together with the punch. The lower part of the rounded article, once, is released from restraining force in the unrestraining part P inside the guide spacer 45 and then ironed again by an ironing part 46a of the 2nd ironing die 46. These are performed continuously by one stroke to obtain a formed article.
