ABSTRACT:
There is disclosed a punch for forging a metallic plate member. A first die is adapted to be opposed to a first face of the plate member. A second die is adapted to be opposed to a second face of the plate member. A plurality of first projections are provided on the first die and arranged in a first direction with a fixed pitch. Each of the first projections is elongated in a second direction perpendicular to the first direction. A plurality of second projections are provided on the second die and arranged in the first direction with the fixed pitch. Each of the second projections is elongated in the second direction and provided with a concave portion extending in the second direction at a distal end portion thereof. The plate member is sandwiched between the first die and the second die so that the first projections and the second projections are cut into the plate member in a third direction orthogonal to the first direction and the second direction, to perform a first forging work.
