ことを特徴とする鍛造型。 In a forging die that presses and constrains the material with an upper die and a lower die to form it into a predetermined shape, one of the upper die and the lower die is used as an inner punch that presses and constrains the center of the material. , pressurize the outer edge of the material.
The outer punch contacts the other die from the early stage of molding to form a sealed product space, while the outer punch separates from the other mold at the end of molding to form a sealed product space. A forging die, characterized in that it is elastically supported to be slidable with respect to the inner punch so as to allow generation of excess thickness between the die and the other die.
