Abstract

PURPOSE: To forge the titled article to a good shape by a small capacity forging machine by fitting a die holder to a tapered outside peripheral surface of a split die, forming a both end flange part by forging an inserted stepped heating blank, and forming a drum part flange by pressing in a punch.
CONSTITUTION: A split die 1 is tightened up by fitting an inclined inside peripheral surface 1A of a die holder 2 to an inclined outside peripheral surface 1A whose diameter is enlarged in the press direction of the split die 1. A stepped heating blank 3 is inserted into a hole in the split die 1 so that a stepped part 3A conforms with the upper flange formed part 2B, and forged, by which the upper and lower flange parts 6A, 6B are formed. Subsequently, by pressing a punch 5 into the center of an upset anvil 4, a drum flange part 6C is formed. By tightening the split die 1 by the tapered die holer 2, its tightening mechanism is simplified and the tightening is executed exactly, and by a two step forging system, the titled good shape and precise article is forged by a small capacity press.
