  • Patent number: 6151948
    Abstract: Methods and apparatuses for near net warm forging relatively small, complex shaped parts, such as automotive rocker arms, is disclosed. Die and punches are provided, which collectively have surfaces corresponding to the surfaces of the as-forged parts. Centralized workpieces, e.g., a transverse cylinders having a length-to-diameter ratio of approximately 1:1, are placed in cavities of the dies, and the punches are cycled through forging strokes to form the as-forged parts. The as-forged parts may have draft angles of 0-2.degree. and surface-to-surface transitions with radii of less than or equal to about 1mm, and may also have substantially parallel side surfaces.
