Abstract (en)

[origin: EP1025925A1] The deforming process involves clamping the metal part (2) in a clamping device (4) to form a forging cavity (13) in the swage (5) with the part clamped to take forging forces directly; applying a forging hammer (7) to force metal into the forging cavity, exerting pressure on the hammer so that the mechanical stress is within the Hooke elastic region, applying a pulse with the hammer so that the metal passes into the flowing region and repeating the last two stages.
