Abstract

PURPOSE: To manufacture a holed member having a good sheared section by half-blanking a plate stock to form a projecting contour, then, piercing the member which is not separated yet from the plate stock, then, punching it and separating the holed member from the plate stock.
CONSTITUTION: The plate stock 21 is carried progressively to press a member 75 having a through hole 73. Consequently, the plate stock 21 is half-blanked by a punch 37 and a die 39 to form a projecting contour 55. Then, a through hole 73 is formed by a punch 45 at a half-blanked part. Thereafter, the holed member 75 is blanked by a punch 59 and a die 61. By this method, a holed member having a good sheared section can be manufactured.
