Abstract

Eine Schmiedemaschine (1) weist wenigstens zwei gegeneinander wirkende, längsgeführte und mechanisch antreibbare Schmiedestempel (2) auf, die aus zwei Teilen, einem antriebsseitigen Oberteil (8) und einem werkzeugseitigen Unterteil (7), bestehen und zwischen dem Oberteil (8) und dem mittels einer Druckfeder (6) gegen den Oberteil (8) druckbeaufschlagbaren Unterteil (7) einen an eine Hydraulikanlage (11) angeschlossenen Hydraulikpolster (9) aufnehmen.A forging machine (1) has at least two counteracting, longitudinally guided and mechanically drivable forging stamps (2) on two parts, a drive-side upper part (8) and a tool-side Lower part (7) exist and between the upper part (8) and by means of a Compression spring (6) against the upper part (8) pressurizable lower part (7) Pick up hydraulic pads (9) connected to a hydraulic system (11).

Um die Schmiedemaschine (1) auch zum Schmieden mit geringen Verformungsgeschwindigkeiten einsetzen zu können, ist die Hydraulikanlage (11) als zusätzlicher Hubantrieb für die Schmiedestempel (2) ausgelegt, über den bei angehaltenem oder hubbewegungsunwirksamem mechanischem Hubantrieb durch Hydraulikmittelbeaufschlagung der Hydraulikpolster (9) jeweils der Unterteil (7) der Schmiedestempel (2) im Sinne einer vom Oberteil (8) unabhängigen Hubbewegung antreibbar ist.

Figure 00000001
In order to be able to use the forging machine (1) also for forging at low deformation speeds, the hydraulic system (11) is designed as an additional lifting drive for the forging punches (2), via which the hydraulic cushion (9) acts upon the hydraulic cushion when the mechanical cushioning is stopped or when the stroke movement is ineffective Lower part (7) of the forging stamp (2) can be driven in the sense of a lifting movement independent of the upper part (8).
