Abstract

PURPOSE:To contrive incorporation of delivery in sequential press processing by putting in before the bending process of a base body portion a cutting process by means of a press shaving off a punch-processed surface at the bending starting point of a cutter base body portion and a blade portion. CONSTITUTION:The 1st holes 25, 26 are punched into a material 23 at the two places of a portion with becomes the side surface 24 of the bending starting point of a cutter base body portion and a retaining portion, and at the same time, material delivery holes 31, 32 are provided at an equal pitch at spaces between every process upward and downward in the width direction of the material 23. With the 1st holes 25, 26 as centers, intermediate holes 27, 28 which are a little large diametered, and next, finishing holes 29, 30 which are slightly larger, are opened on the same shaft core by means of a shaving processing. Next, the outline of a blade portion 33 is punched by a press on the side surface 24 of the bending starting point of the blade portion 33 in such a way that portions of finishing holes 29, 30 remain. Afterward, bending is done. The side surface 24 which has a clean surface as a hardening layer is gone, is finished by means of this process, and a shaving processed surface remains at the bending starting point, even if punched with an ordinary press, and a crack does not occur at the time of bending.
