Description

Die Erfindung betrifft eine mechanische Presse mit einem Doppelpleuelantrieb, der eine Antriebseinheit aus Schwung­rad, mit einer Kupplungswelle versehener hydraulischer Kupplungs/Bremseinheit, Planetengetriebe und Kurbelwelle aufweist.The invention relates to a mechanical press with a double connecting rod drive, which has a drive unit comprising a flywheel, a hydraulic clutch / brake unit provided with a clutch shaft, a planetary gear and a crankshaft.

Eine aus der Praxis bekannte, druckschriftlich nicht nä­her belegte Presse der genannten Art weist nur eine ein­zige Antriebseinheit auf, die seitlich an die Presse ange­setzt ist und die beide Pleuel betätigende Kurbelwelle antreibt. Nachteilig sind hierbei zunächst der lange Dreh­momentenweg und damit die geringe Drehsteifigkeit. Störend sind außerdem die einseitige Drehmomenteneinleitung und damit die unterschiedliche Drehsteifigkeit an den Pleuel­stellen. Außerdem wird erheblicher Bauraum nach der Seite hin beansprucht.A press of the type mentioned which is known from practice and is not documented in detail in writing has only a single drive unit which is attached to the side of the press and which drives the crankshaft that actuates both connecting rods. The disadvantage here is the long torque path and thus the low torsional rigidity. The one-sided introduction of torque and thus the different torsional stiffness at the connecting rod points are also disturbing. In addition, considerable space is required to the side.

Der Erfindung liegt die Aufgabe zugrunde, eine Presse der eingangs genannten Art bezüglich ihres Antriebes so weiter­zuentwickeln, daß dieser in den übrigen Bauraum der Presse integriert wird und besonders kurze Drehmomentenwege sowie damit extreme und gleichseitige Steifigkeit aufweist.The invention has for its object to develop a press of the type mentioned in terms of its drive so that it is integrated in the remaining space of the press and has particularly short torque paths and thus extreme and equilateral rigidity.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß zwischen den beiden Pleueln symmetrisch zur Pressen­mittelebene zwei bis auf ihre Spiegelsymmetrie identisch aufgebaute, zueinander koaxiale Antriebseinheiten ange­ordnet sind, deren Kupplungswellen an ihren einander zu­gewandten Wellenenden zu einer einzigen Welle miteinander vereinigt sind und deren Kupplungs/Bremseinheiten von einer gemeinsamen zentralen Hydraulikmittelzuführung ge­speist sind.The solution to this problem according to the invention is that between the two connecting rods, symmetrically to the press center plane, two identical coaxial drive units, apart from their mirror symmetry, are arranged, the coupling shafts of which are combined into a single shaft at their mutually facing shaft ends, and their clutch / brake units of are fed a common central hydraulic fluid supply.

Die Erfindung geht hierbei von der Überlegung aus, daß durch die symmetrische Drehmomenteneinleitung zu und zwi­schen den Pleuelstellen bei kompakten Pressenabmessungen die Gewähr für einen synchronen und gleichmäßigen Kraft­angriff gegeben ist.The invention is based on the consideration that the symmetrical introduction of torque to and between the connecting rods with compact press dimensions guarantees a synchronous and uniform application of force.

Für die weitere Ausgestaltung bestehen im Rahmen der Er­findung mehrere Möglichkeiten. So sind die beiden Antriebs­einheiten vorzugsweise in einem gemeinsamen Antriebsge­häuse untergebracht. Dabei ist dann eine besonders gute Zugänglichkeit beispielsweise für Reparatur- und Wartungs­zwecke gegeben, wenn das Antriebsgehäuse horizontal in zwei Gehäuseteile geteilt ist, die mittels Zuganker mit­einander verspannt sind. Das Antriebsgehäuse wird man ggf. zweckmäßigerweise vom Pressenständer oder -gehäuse bilden. In der Ausführungsform als Kurbel- und Exzenterpresse ist es ohne weiteres möglich, das z. B. vom Ständer gebildete Antriebsgehäuse in einem Hohlraum des Stößels vorzusehen. In konstruktiver Hinsicht ergeben sich darüber hinaus be­sonders überschaubare Verhältnisse, wenn die Kupplungs/­Bremseinheiten ein gemeinsames Kupplungsgehäuse aufweisen, welches die Schwungräder trägt. Die Hydraulikmittelzufüh­rung ist dabei mit einer berührungslosen, verschleißfreien Labyrinthdichtung im Kupplungsgehäuse versehen. Konstruk­tiv besonders einfach ist weiterhin die Anordnung, bei der die Kupplungswellen mit ihrem Außenende im zugewandten Innenende der jeweils zugeordneten Kurbelwelle gelagert sind. Das gleiche gilt dann, wenn die Kupplungswellen im Bereich ihrer Außenenden Verzahnungen als Sonnenräder der Planetengetriebe aufweisen. Die Planetenräder der Plane­tengetriebe sind zweckmäßigerweise auf Zapfen gelagert, die an Innenwangen der Kurbelwellen angeformt oder in diese eingesetzt sind. Zur Gewährleistung einer gleich­mäßigen Getriebebelastung sollten die Hohlräder der Pla­netengetriebe in ortsfeste Stützringe mittels einer Ver­zahnung verdrehsteif, aber radial beweglich gelagert sein. Im übrigen läßt sich die Kompaktheit erhöhen, wenn die Kurbelwellen auf ihren beiden Wangen gelagert sind.There are several possibilities for the further configuration within the scope of the invention. The two drive units are preferably housed in a common drive housing. This provides particularly good accessibility, for example for repair and maintenance purposes, if the drive housing is horizontally divided into two housing parts which are clamped together by means of tie rods. If necessary, the drive housing will expediently be formed by the press stand or housing. In the embodiment as a crank and eccentric press, it is easily possible that the z. B. provided by the stator drive housing in a cavity of the plunger. In terms of design, there are also particularly manageable conditions if the clutch / brake units have a common clutch housing which carries the flywheels. The hydraulic fluid supply is provided with a non-contact, wear-free labyrinth seal in the coupling housing. The arrangement in which the coupling shafts with their outer ends face in is particularly simple in terms of construction Inner end of the associated crankshaft are mounted. The same applies if the coupling shafts have teeth in the area of their outer ends as sun gears of the planetary gear. The planet gears of the planetary gears are expediently mounted on pins which are formed on the inner cheeks of the crankshafts or are inserted into them. To ensure a uniform load on the gearbox, the ring gears of the planetary gearboxes should be mounted in a fixed support ring by means of toothing in a torsionally rigid but radially movable manner. In addition, the compactness can be increased if the crankshafts are supported on their two cheeks.

Die in den Figuren dargestellten Pressen sind mechanische Pressen mit einem Doppelpleuelantrieb. Der Doppelpleuel­antrieb ist aus jeweils zwei Antriebseinheiten 1 aufge­ baut, deren jede aus einem Schwungrad 2, einer mit einer Kupplungswelle 3 versehenen hydraulischen Kupplungs/Brems­einheit 4, einem Planetengetriebe 5 und einer Kurbelwelle 6 aufgebaut ist. Diese beiden Antriebseinheiten 1 sind zwischen den beiden Pleueln 7 symmetrisch zur Pressenmit­telebene angeordnet und bis auf ihre Spiegelsymmetrie identisch aufgebaut sowie zueinander koaxial angeordnet. Die Kupplungswellen 3 sind an ihren einander zugewandten Wellenenden 8 zu einer einzigen Welle miteinander verei­nigt. Die Kupplungs/Bremseinheiten 4 sind von einer gemein­samen zentralen Hydraulikmittelzuführung 9 gespeist, deren Einzelheiten aus Fig. 7 deutlicher ersichtlich sind.The presses shown in the figures are mechanical presses with a double connecting rod drive. The double connecting rod drive is made up of two drive units 1 each builds, each of which is constructed from a flywheel 2, a hydraulic clutch / brake unit 4 provided with a clutch shaft 3, a planetary gear 5 and a crankshaft 6. These two drive units 1 are arranged symmetrically to the plane of the press between the two connecting rods 7 and, apart from their mirror symmetry, are constructed identically and are arranged coaxially with one another. The coupling shafts 3 are combined to form a single shaft at their mutually facing shaft ends 8. The clutch / brake units 4 are fed by a common central hydraulic medium feed 9, the details of which can be seen more clearly from FIG. 7.

Die beiden Antriebseinheiten 1 sind in einem gemeinsamen Antriebsgehäuse 10 untergebracht. Die Schwungräder 2 wer­den über verbundene Kettenräder und Ketten 22, die durch Schlitze in das Antriebsgehäuse geführt sind, von einem Antriebsmotor angetrieben. In allen Fällen ist dieses An­triebsgehäuse 10 horizontal in zwei Gehäuseteile geteilt, die mittels Zuganker 11 miteinander verspannt sind. Bei allen Ausführungsformen ist das Antriebsgehäuse 10 vom Pressenständer bzw. -gehäuse 12 gebildet. Bei der Aus­führungsform nach den Fig. 5 und 6 ist das Antriebsgehäuse teilweise in einem Hohlraum des Stößels 13 angeordnet.The two drive units 1 are accommodated in a common drive housing 10. The flywheels 2 are driven by a drive motor via connected chain wheels and chains 22, which are guided through slots in the drive housing. In all cases, this drive housing 10 is horizontally divided into two housing parts which are clamped together by means of tie rods 11. In all embodiments, the drive housing 10 is formed by the press stand or housing 12. In the embodiment according to FIGS. 5 and 6, the drive housing is partially arranged in a cavity of the plunger 13.

Wie man aus den Fig. 1, 3 und 5 ohne weiteres erkennt, weisen die Kupplungs/Bremseinheiten 4 ein gemeinsames Kupplungsgehäuse 14 auf, welches die Schwungräder 2 trägt. Die Hydraulikmittelzuführung 9 ist mit einer berührungs­losen, verschleißfreien Labyrinthdichtung 23 im Kupplungs­ gehäuse 14 versehen (vgl. Fig. 7), d. h. die Einführung des Hydraulikmittels in die beiden hydraulischen Kupp­lungs/Bremseinheiten 4 vom Kupplungsgehäuse 14 her in den Mittelteil der Kupplungswelle 3 erfolgt durch die Laby­rinthdichtung 23. Die Kupplungswellen 3 sind mit ihrem Außenende im zugewandten Innenende der jeweils zugeordne­ten Kurbelwelle 6 gelagert. Im übrigen weisen die Kupp­lungswellen 3 im Bereich ihrer Außenenden Verzahnungen 15 als Sonnenräder der Planetengetriebe 5 auf. Die Plane­tenräder 16 der Planetengetriebe 5 sind auf Zapfen 17 ge­lagert, die an Innenwangen 18 der Kurbelwellen 6 angeformt oder in diese eingesetzt sind. In diesen Innenwangen 18 sind auch die Kupplungswellen 3 gelagert. Die Hohlräder 19 der Planetengetriebe 5 sind in ortsfesten Stützringen 20 mittels einer Verzahnung verdrehsteif, aber radial be­weglich gelagert.1, 3 and 5, the clutch / brake units 4 have a common clutch housing 14 which carries the flywheels 2. The hydraulic medium supply 9 is with a non-contact, wear-free labyrinth seal 23 in the coupling Housing 14 provided (see FIG. 7), ie the introduction of the hydraulic fluid into the two hydraulic clutch / brake units 4 from the clutch housing 14 into the central part of the clutch shaft 3 is carried out through the labyrinth seal 23. The outer end of the clutch shafts 3 is in the inner end facing associated crankshaft 6. Otherwise, the coupling shafts 3 have teeth 15 in the area of their outer ends as sun gears of the planetary gear 5. The planet gears 16 of the planetary gear 5 are mounted on pins 17 which are formed on the inner cheeks 18 of the crankshafts 6 or are inserted into them. The coupling shafts 3 are also supported in these inner cheeks 18. The ring gears 19 of the planetary gear 5 are torsionally rigid but radially movable in fixed support rings 20 by means of teeth.

Bei der Ausführungsform nach den Fig. 1 bis 4 handelt es sich jeweils um eine Kniehebelpresse, bei der die Pleuel 7 auf Kniehebel 21 arbeiten, die zwischen Rahmen und Stös­sel 13 angeordnet sind. Bei der Ausführungsform nach den Fig. 1 und 2 ist der Doppelpleuelantrieb unten angeordnet, bei der Ausführungsform nach den Fig. 3 und 4 dagegen oben.
