Abstract

Eine Rundknetmaschine (1) umfaßt in radialen Ausnehmungen (4) eines um die Durchlaufachse (A) dreh- und antreibbar gelagerten Schmiedekastens (3) hubbewegbar geführten Hämmereinheiten (5) und sich an einem den Schmiedekasten (3) umgebenden koaxialen Stützring (8) abstützende Druckglieder, wobei der Schmiedekasten (3) und/oder der Stützring (8) relativ zueinander umlaufend antreibbar sind und die Druckglieder auf die mit einem Kopfteil in die Umlaufbahn der Druckglieder vorragenden Hämmereinheiten (5) beim jeweiligen Vorbeibewegen im Sinne eines einwärts gerichteten Druckimpulses einwirken.
Um einen robusten, verschleißarmen Hubantrieb zu erreichen, bestehen die Druckglieder aus einer Druckplatte (10), die wippenartig um eine zur Durchlaufachse (A) parallele Wippachse (B) anschlagbegrenzt verschwenkbar an einem im Stützring (8) drehfest sitzenden Druckstempel (9) angelenkt ist, und weisen die Hämmereinheiten (5) als Kopfteil eine den Druckplatten (10) zugeordnete, wippenartig um eine zur Durchlaufachse (A) parallele Wippachse (C) anschlagbegrenzt verschwenkbare Gegendruckplatte (13) auf, wobei Druckplatten (10) und Gegendruckplatten (13) zusammenwirkende Gleitflächen (16, 17) bilden und über Rückstellfedern (18, 19) in Richtung einer bezüglich der jeweiligen Relativverdrehung (R) von Schmiedekasten (3) und Stützring (8) vorwärts geneigten Ausgangsstellung druckbeaufschlagbar sind.
