Abstract

A press die assembly includes a lower die, an upper die, a stripper plate provided between the lower die and the upper die, and a coupling member that couples the upper die and the stripper plate to each other such that the upper die and the stripper plate are movable relative to each other. The upper die includes a punch, an upper die main body, and an elastic member. The punch includes a first large-diameter portion and a second large-diameter portion. The upper die main body includes a restricting portion that restricts downward movement of the punch by contacting the second large-diameter portion. The elastic member is configured to urge the punch toward the restricting portion and to allow the upper die main body to approach the punch by being compressively deformed in a state in which the first large-diameter portion is in contact with the stripper plate.
