Abstract
Description
Die Erfindung bezieht sich auf eine Brückenstanze, deren Druckbalken durch ein mechanisches Hebelsystem hydraulisch bewegt wird.The invention relates to a bridge punch, their pressure bars by a mechanical lever system is moved hydraulically.
Bekannt sind bei hydraulisch angetriebenen Pressen bzw. Stanzen, z. B. durch die OS 19 64 133, OS 20 15 342, OS 30 11 281, die trotz aufwendiger Gleichlaufsteuerungen für den parallelen Antrieb mit Schutzkolben nur eine ungenügende Parallelität zwischen Stanzfläche und Gegenfläche erzielen.Are known in hydraulically driven presses or Punching, e.g. B. by OS 19 64 133, OS 20 15 342, OS 30 11 281, which despite complex synchronization controls for the parallel drive with protective piston only insufficient parallelism between the punching surface and Achieve counter surface.
Das weniger aufwendige Erzielen der besseren Parallelität zwischen Druckbalken und Gegenbalken bei der Bewegung nach oben wird erfindungsgemäß dadurch gelöst, daß durch ein mechanisches Hebelsystem und die Einwirkung von fünf Druckkräften auf den Druckbalken eine Parallelführung bei unterschiedlichen Stanzkräften und Kraftangriffspunkten erreicht wird.The less complex achievement of better parallelism between pressure bar and counter bar during movement is solved according to the invention in that through a mechanical lever system and the action parallel guidance of five pressure forces on the pressure beam with different punching forces and force application points is achieved.
Die Erfindung soll an nachfolgendem Ausführungsbeispiel erläutert werden. In den zugehörigen Zeichnungen zeigen:The invention is based on the following embodiment are explained. In the accompanying drawings:
Fig. 1 die Vorderansicht der Brückenstanze im Teilschnitt, Fig. 1 is a front view of the bridge punch in partial section,
Fig. 2 eine vergrößerte Schnittdarstellung eines im Druckbalken gelagerten Exzenters, Fig. 2 is an enlarged sectional view of a pressure bar mounted in the eccentric,
Fig. 3 eine Seitenansicht nach Fig. 1 im Teilschnitt, Fig. 3 is a side view of FIG. 1 in partial section,
Fig. 4 eine Draufsicht nach Fig. 1 im Schnitt. Fig. 4 is a plan view of FIG. 1 in section.
In der Fig. 1 ist die Anordnung der aus Druckbalken, Schubkolbenbetrieb, Lagergabel, Ausgleichskoppel, Hebel, Schubstangen usw. bestehenden erfindungsgemäßen Vorrichtung gezeigt. In FIG. 1, the arrangement of the so consisting of the pressure beam, thrust piston operating, storage fork, compensation coupling, levers, thrust rods device of the invention is shown.
Für den im Gestell 1 geführten Druckbalken 2 ist ein hydraulischer Schubkolbentrieb 3 vorgesehen, der so im Druckbalken 2 gelagert ist, daß die Anlenkung des Schubkolbentriebes 3 an die Hebel 4 für die Krafteinleitung eine Geradführung darstellt.For the pressure beam 2 guided in the frame 1 , a hydraulic thrust piston drive 3 is provided, which is mounted in the pressure beam 2 in such a way that the articulation of the thrust piston drive 3 to the lever 4 for the introduction of force represents a straight line.
Die Kolbenstange 5 ist mit einer Lagergabel 6 versehen, auf deren Bolzen 7 die zur Kraftübertragung auf die Hebel 4 erforderliche Ausgleichkoppel 8 gelagert ist. Eine Verbindung der Ausgleichskoppel 8 und den Hebeln 4 erfolgt durch die Bolzen 9.The piston rod 5 is provided with a bearing fork 6 , on the bolt 7 of which the compensation coupling 8 required for power transmission to the lever 4 is mounted. The compensating coupling 8 and the levers 4 are connected by the bolts 9 .
Die im Gestell 1 fest angeordneten Lager 10; 11 halten die Achsen 12, auf denen die Hebel 4 drehbar gelagert sind, an deren Enden mittels Bolzen 13 vier Schubstangen 14; 15 angelenkt werden, die im Druckbalken 2 gelagert sind.The fixedly arranged in the frame 1 bearing 10; 11 hold the axles 12 on which the lever 4 are rotatably supported at the ends by means of bolts 13, four push rods 14; 15 are articulated, which are mounted in the pressure beam 2 .
Die oberen Enden der Schubstangen 14; 15 sind mit in Fig. 2 dargestellten Exzentern 16 versehen, mit denen die Parallelität zwischen Druckbalken 2 und Gegenbalken 17 durch eine einmalige Einstellung hergestellt wird und beim Arbeitshub des Druckbalkens 2 immer exakt eingehalten wird.The upper ends of the push rods 14 ; 15 are provided with eccentrics 16 shown in FIG. 2, with which the parallelism between the pressure beam 2 and counter beam 17 is established by a single adjustment and is always exactly maintained during the working stroke of the pressure beam 2 .
Beim Auslösen des Arbeitshubes wird der Schubkolbentrieb 3 oberhalb des Kolbens 18 hydraulisch mit Druck beaufschlagt, die Kolbenstange 5 bewegt sich nach unten und überträgt die Kolbenkraft über das Hebelsystem auf den Druckbalken 2.When the working stroke is triggered, the thrust piston drive 3 is hydraulically pressurized above the piston 18 , the piston rod 5 moves downward and transmits the piston force to the pressure beam 2 via the lever system.
Die Kolbengegenkraft wirkt direkt auf den Druckbalken 2 und führt somit zu einer Verdopplung der Antriebskraft.The piston counterforce acts directly on the pressure beam 2 and thus leads to a doubling of the driving force.
Wirken während des Stanzhubes auf den Druckbalken 2 unterschiedliche Stanzkräfte durch z. B. ungleichmäßige Verteilung der Schnittflächen, bleibt aufgrund des für die Krafteinteilung vom Schubkolbentrieb 3 wirkenden geschlossenen Hebelsystems die Parallelität zwischen Druckbalken 2 und Gegenbalken 17 gewährleistet.Act during the punch stroke on the pressure beam 2 different punching forces by z. B. uneven distribution of the cut surfaces, the parallelism between the pressure beam 2 and counter beam 17 remains ensured due to the lever system acting for the force distribution from the thrust piston drive 3 .
