Abstract

Gemäß der Erfindung werden
a) das Werkstück (10) in eine vorgegebene oder vorgebbare Uinfortnlage in wenigstens einen Arbeitsbereich wenigstens einer Umformmaschine zwischen zwei zugehörigen Werkzeugen (12,13) positioniert,
b) während wenigstens eines Umformschrittes die Werkzeuge der Umformmaschine relativ aufeinander zu bewegt und das Werkstück zwischen den Werkzeugen umgeformt,
c) während jedes Umformschrittes das Werkstück von wenigstens zwei Handhabungsgeräten (2,2') in seiner Umformlage festgehalten,
d) die Bewegungen und Positionen der Handhabungsgeräte von wenigstens einer Kontrolleinrichtung (43) automatisch und aufeinander abgestimmt gesteuert oder geregelt,
e) als Werkzeuge (12,13) der Umformmaschine formgebende Gesenkwerkzeuge zum gebundenen Umformen des Werkstückes vorgesehen; und
f) als Umformmaschine eine schlagende Umformmaschine, insbesondere ein Schmiedehammer oder eine Spindelpresse, oder eine Kurbelfresse vorgesehen.
