Claims

[Claims for Utility Model Registration] (1) A pair of punch and die, and an ejector pin that has a molding surface that matches the cavity of the die at its upper end and a swollen portion at its lower end, and is capable of receiving pressure. A forging device in which a spacer is interposed between a plate and the lower end of the ejector pin, characterized in that the ejector pin and the spacer are connected by a removable coupling element across the enlarged diameter portion. Device. (2) The above-mentioned coupling element is constituted by a needle-shaped member which goes around the part directly above the above-mentioned expanded diameter part and whose both ends are inserted into the small holes of the spacer.
Apparatus described in section. (3) The device according to claim 1, wherein the coupling element is constituted by a plate-like member that is fitted directly above the expanded diameter portion and holds the stepped shoulder portion of the spacer.
