To provide a sequential forming apparatus that improves productivity of forming components by enhancing freedom of movement of a forming roller, and also to provide its method.
In the sequential forming apparatus 1, a component 2 to be formed is plastically deformed by a forming roller 5 to sequentially form a component of a rotation symmetry shape. The forming roller 5 includes a roller part 50 with a circular arc forming face 50a formed by which the component 2 to be formed is pressurized and a shaft part 51 on which the roller part 50 is rotatably supported axially. With the component 2 to be formed pressurized by the forming face 50a of the roller part 50, while the relative angle of the rotary axis S2 of the roller part 50 is varied against the rotary axis S1 of the component 2 to be formed, the roller part 50 is moved in the axial direction of the rotary axis S1 of the component 2 to be formed. Thus, the state of pressurized contact of the forming face 50a of the roller part 50 is varied for the component 2 to be formed.
