特徴とするクランクプレス。A bolster to which the lower mold is attached is constituted by one or more members, and an upper surface portion of the bolster to which the lower mold is directly attached is a convex portion, and an upper surface side groove is formed around the convex portion, and an upper side groove is formed around the convex portion, and the upper surface groove corresponds to the convex portion. A lower surface side groove is formed around the periphery of the screen by using the lower surface portion ``as a recessed portion'', and the upper and lower side grooves are arranged to face each other, and the distance between the bottoms of the grooves is a predetermined thickness dimension. A crank press characterized in that shear damage occurs between side grooves on the upper and lower surfaces of the bolster only when a force exceeding a predetermined load is applied when the upper mold is applied to the lower mold.
