Billet manipulator

摘要

Apparatus for rotating a billet. A frame presents an upwardly facing surface to support a billet, the surface having a slope so that the rectangular billet presents a surface which slopes toward an operator for the purpose of grinding and the like. The frame supports a plurality of lift arms having L-shaped ends which are adapted to engage a corner of a billet and lift the billet to cradle it for corner grinding and then to lower the billet to present a new surface for grinding. The frame also carries a plurality of clamp arms for engaging one side of a billet and pushing it against an abutment projecting above the surface of the frame to clamp it there during the grinding operation. The frame also supports a plurality of eject arms mounted on a common shaft for discharging a billet from the frame.
