Abstract

PURPOSE:To surely subject a product with a boss to pressing even in case of a long boss by drawing a projecting part at the vicinity of the hole for metal drawing-up after punching it on a metal plate stock and punching it in the specified shape after burring it. CONSTITUTION:The hold 25 for metal drawing-up is formed by punching at the vicinity of the boss 23 working part of a metal plate stock 21. This hole 25 for metal drawing-up is preferably formed in the semicircular arcuated shape surrounding the boss 23 working part. A projecting part 27 is then formed at said boss working part by drawing. The metal plate stock 21 of between the hole 25 for metal drawing-up and boss working part is thus easily flowed into the projecting part 27. A prepared hole 29 is then pierced at the center of the projecting part 27 and a specified through hole 31 is formed. The boss 23 is then formed by executing burring on this projecting part 27. The product with a boss of the specified shape is thereafter punched from the metal plate stock 21 and a bell crank, etc., are obtd.
