Abstract

Eine Schmiedemaschine (1) weist wenigstens zwei gegeneinander wirkende, in einem Maschinengestell (2) längsgeführte Schmiedestempel (5) auf, die jeweils eigene Hubantriebe (9) und Hublagenverstelleinrichtungen (10) besitzen. Um die Schmiedemaschine (1) bei einfachem Aufbau für einen großen Schmiedebereich zu eignen, sind jeder Schmiedestempel (5) samt Längsführung (8) und Hublagenverstelleinrichtung (10) und der zugehörige Hubantrieb (9) zu einer Schmiedeeinheit (3) zusammengefaßt und in einem eigenen Gehäuse (7) angeordnet, das im Maschinengestell (2) verschwenkbar oder verschiebbar lagert und sich zum Verstellen an einem Stelltrieb (11) abstützt.

Figure 00000001
A forging machine (1) has at least two forging dies (5) which act in a longitudinal direction in a machine frame (2) and each have their own lifting drives (9) and stroke position adjustment devices (10). In order to make the forging machine (1) suitable for a large forging area with a simple construction, each forging punch (5) together with the longitudinal guide (8) and stroke position adjustment device (10) and the associated lifting drive (9) are combined to form a forging unit (3) and in their own Housing (7) is arranged, which is pivotably or displaceably mounted in the machine frame (2) and is supported for adjustment on an actuator (11).
