Patent Number: 7,131,311

Title: Method of and apparatus for forming forging blank

Abstract: When an actuator is operated, an upper die is displaced downwardly, pressing a lower surface of a workpiece against a forming surface. After the upper die is displaced upwardly, an ejecting member is displaced upwardly to push the workpiece upwardly by a lower die. As the workpiece is displaced upwardly, an outer circumferential surface of the workpiece is squeezed by a squeezer projecting radially inwardly from an inner circumferential surface of an outer ring.
