20090071219 | APPARATUS AND METHOD FOR FORGING PREMIUM COUPLING BLANKS - A method and apparatus for forging a tubular forging stock to produce a forged product, preferably a premium coupling machining blank. The apparatus includes a holding die assembly defining a holding cavity for the forging stock and a press die apparatus including opposed first and second press dies movable within the holding cavity to forge the forging stock to produce the forged product. The holding die assembly may include opposed first and second holding dies defining respective portions of the holding cavity, wherein the holding dies are selectively relatively movable between a closed position for forging the forging stock and an open position for removal of the forged product. Alternately, the apparatus may include a knockout mechanism for dislodging the forged product from the holding cavity. Further, the apparatus may include a mechanism for controlling finning between the first and second press dies while the forged product is being produced. | 03-19-2009 |
