Abstract

PURPOSE: To eliminate the need for costly dies provided with precision hole sizes by making use of the hole of the previously blanked metal plate in place of dies in the case of blanking the metal products of a fixed shape from a metal plate by means of a die and a punch.
CONSTITUTION: A metal plate 12 being "slug" which has a previously blanked hole 14 is placed on a base 11 and the hole 14 and a punch 3 are so set as not to have any position deviation. With this metal plate 12 being utilized as a die, a material plate 13 is placed thereon. The punch 3 is forced down to blank the metal plate 13 and the blanked product 15 is held in place in the hole 14 of the metal plate 12. Next, the punch is reset, the metal plate 12 is drawn out and the product 15 in the hole 14 is pushed out and is recovered. The blanked metal plate 13 serves as a die and the operation similar to before is repeated, whereby the blanked product is made. There is no need for any particularly precise dies and there is no need for repair of the dies, thus this is extremely economical.
