Abstract
A forging device capable of producing a high-quality forged article while simplifying the structure is provided. The forging device of the present invention includes a punch, a diehaving a shaping holeand a helical blade portionformed on an inner peripheral surface of the shaping hole, a back pressure generation mechanism, and a back pressure transmission mechanism. The back pressure transmission mechanism includes a rotation-side transmission member having a back pressure plateand a non-rotation-side transmission member. The back pressure plateis arranged in the shaping holein a fitted manner. When a forging material Wis driven into the shaping holeand the back pressure plateis pressed downward by the metallic material, the back pressure plateis guided by the blade portionof the shaping holeand thereby descends while rotating about the axis and a back pressure by the back pressure generation mechanismis applied to the metallic material via the back pressure transmission mechanism.
