ABSTRACT:
This invention relates to apparatus for forming shaped pieces. One embodiment useful in forming metal parts, such as fins for use in the compressor section of gas turbines, comprises apparatus for use with a flat-surfaced die having a forming die depression in the upper surface, which has a pair of cylindrical rolls oriented with their axes parallel and positioned one above the other between the flat surface of the die and the lower surface of a downward acting hydraulic press, with the rolls simultaneously moveable horizontally and in rolling contact with each other, the upper surface of the die, and the lower surface of the hydraulic press platen, by a horizontally oriented hydraulic ram. The platen and the die are limited as to how close they may come to each other, and the rolls are free to "float" away from the die and toward the platen as the lower roll comes into contact with the work piece. Stock may be positioned atop the die and rolled in successive reduction passes into the desired shape and dimensions as determined by the depression in the die.
