Abstract

Eine Schmiedemaschine (1) umfaßt wenigstens zwei gegeneinander wirkende, in einem Schmiedekasten (3) längsgeführte Schmiedestempel (3), die jeweils eigene mechanische Hubantriebe und vorzugsweise Hublagenverstelleinrichtungen aufweisen. Um bei hohen Maschinensteifigkeiten und vereinfachter - Bauweise einen robusten Hubantrieb zu erreichen, bestehen die Hubantriebe aus einem Taumelscheibentrieb (5) mit einer im Schmiedekasten (1) um eine zur jeweiligen Schmiedestempelachse (S) parallel versetzte Taumelachse (T) dreh- und antreibbar, aber verschiebefest gelagerten Taumelscheibe (6) und einer der Taumelscheibe (6) zugeordneten, kugelgelenkartig an der taumelscheibenzugewandten Stirnseite des zugehörenden Schmiedestempels (3) abgestützten Druckscheibe (9), wobei vorzugsweise die Schmiedestempel (3) über Druckfedern (11) im Sinne einer kraftschlüssigen Verbindung von Taumelscheiben (6) und Druckscheiben (9) druckbeaufschlagbar sind.

Figure 00000001
A forging machine (1) comprises at least two forging punches (3) which act counter to one another and are longitudinally guided in a forging box (3), each of which has its own mechanical lifting drives and preferably stroke position adjustment devices. In order to achieve a robust stroke drive with high machine stiffness and simplified construction, the stroke drives consist of a swash plate drive (5) with a swash axis (T) offset in the forging box (1) around a swash axis (T) which is offset parallel to the respective forging punch axis (S), but Swashplate (6) with a fixed displacement and a swashplate (6) assigned to the swashplate (6) and supported on the swashplate end facing the associated forging punch (3) Swash plates (6) and pressure plates (9) can be pressurized.
