PATENTANSPRUCH:PATENT CLAIM:Vorrichtung .zum Streckschmieden bildsamen, insbesondere metallischen Werkstoffes mit
Hilfe eines in Schwingungen versetzten Werkzeuges, das aus gegenläufig auf das Werkstück
wirkenden, durch Kurbel- oder Exzentertriebe symmetrisch angetriebenen Schwingerbacken besteht,
die während des wirksamen Teiles ihrer gegenseitigen Annäherung sich der Ausgangsseite
des Werkstückes zu bewegen, dieses dabei unter gleichzeitigem Verformen vorwärts schieben
und dann sich öffnend wieder zu dessen Eingangsseite •zurückschwingen, nach Patentanmeldung
ρ 41458 Ib/49h D, dadurch gekennzeichnet,
daß die Arbeitsflächen der Schwingerbacken wellen- oder sägezahnförmig- gerippt sind.Device .zum stretch forging with plastic, in particular metallic material
With the help of a tool that is set in vibration, which runs in opposite directions on the workpiece
active oscillating jaws, symmetrically driven by crank or eccentric drives,
those during the effective part of their mutual approach to the exit side
to move the workpiece, pushing it forward while simultaneously deforming it
and then swing back to the entrance side • after patent application
ρ 41458 Ib / 49h D, characterized in that
that the working surfaces of the rocker jaws are corrugated or sawtooth-shaped.
