| 摘要 |
The present invention is directed to a method of producing a series of individual forged articles from a feedstock produced on a continuous rotary extrusion machine from metal powder supplied thereto; comprises repeating a cycle of steps, the steps being characterised by comprising, in any appropriate sequence:- i) extruding the feedstock into a tooling chamber 10 initially to form a blank in a mould chamber 12 comprising part of the tooling chamber, the mould chamber being moveable between a first position and a second position to separate the material in the mould chamber from the feedstock; ii) stopping extrusion of the feedstock; iii) moving the mould chamber 12 from the first position to the second position; iv) with the mould chamber in the second position, ejecting the material from the mould chamber; v) forging the blank to produce an article; and vi) moving the then hollow mould chamber from the second position to the first position. |
