Claims

[Scope of utility model registration request]

an upper mold body is installed so as to be movable toward and away from the lower mold body; a die sliding body is mounted on the lower mold body so as to be swingable in a plane transverse to the direction of the relative approach and departure; A die into which the bottomed part side of a cylindrical workpiece with a bottom is fitted is fixed to the die rocking body, and a support plate provided so as to be movable toward and away from the upper mold body cooperates with the die. a punch that shears the workpiece in a plane perpendicular to the cylindrical surface of the workpiece, and restricts relative approaching movement of the punch after the upper die body approaches the lower die body by a predetermined distance. A distance is provided between the support plate and the lower mold body, and the die oscillating body prevents the upper mold body from moving toward the lower mold body in a state where the relative approaching movement of the punch is restricted. A press die in which a drive cam that converts into rocking motion is fixed to the upper die body, and a nest that supports the workpiece is fixed to the lower die body.
