Description
Die vorliegende Erfindung betrifft eine Maschinenpresse, insbesondere Abkantpresse, mit einer Maschinenstruktur, einem in fester räumlicher Beziehung zu der Maschinenstruktur angeordneten unteren Werkzeugträger, einem oberen Werkzeugträger, der relativ zu dem unteren Werkzeugträger um einen Betriebshub linear auf und ab verfahrbar ist, und einem auf den oberen Werkzeugträger wirkenden, die abwärts gerichtete Bewegung des oberen Werkzeugträgers bewirkenden geschlossenen hydraulischen Antriebssystem, welches mindestens eine hydraulische Antriebseinheit aufweist, welche ihrerseits mindestens eine hydraulische Zylinder-Kolben-Einheit und mindestens ein diese beaufschlagendes, aus einem Vorratsbehälter versorgtes Hydraulikaggregat umfasst, wobei in dem Vorratsbehälter ständig ein über dem Umgebungsdruck liegender Basisdruck herrschtThe present invention relates to a machine press, in particular a press brake, having a machine structure, a fixed in a spatial relationship to the machine structure lower tool carrier, an upper tool carrier which is relative to the lower tool carrier linearly moved up and down by a power stroke, and one on the upper tool carrier acting, the downward movement of the upper tool carrier causing closed hydraulic drive system comprising at least one hydraulic drive unit, which in turn comprises at least one hydraulic cylinder-piston unit and at least one of these acting, supplied from a reservoir hydraulic unit, wherein in the reservoir constantly above the ambient pressure lying base pressure prevails

Die vor iegende Erfindung ist darauf gerichtet, eine hinsichtlich wesentlicher praxisrelevanter Aspekte optimierte Maschinenpresse der gattungsgemäßen Art bereitzustellen, wobei es insoweit namentlich um Aspekte der Baugröße und des baulichen Aufwands - und somit auch der Herstellungskosten - geht.The voriegende invention is directed to provide optimized in terms of essential practical aspects machine press of the generic type, which is so far in particular by aspects of the size and structural complexity - and thus the production costs - goes.
Gelöst wird die vorstehend bezeichnete Aufgabenstellung gemäß der vorliegenden Erfindung bei einer Maschinenpresse mit den Merkmalen des Anspruchs 1. Namentlich bei besonderes großen und leistungsfähigen Maschinenpressen lassen sich auf dieses Weise gegenüber dem Stand der Technik signifikante Vorteile erreichen; denn selbst bei Maschinenpressen mit einem vergleichsweise großen benötigten Wechselvolumen, welches bei erfindungsgemäßen Maschinenpressen durch die Differenz zwischen dem maximalen und dem minimalen Volumen des Hydraulikraums des Zylinderspeichers definiert ist, lässt sich mit einem vergleichsweise kleinen Hochdruck-Gasspeicher sicherstellen, dass in der mindestens einen hydraulischen Antriebseinheit ständig, d.h. über sämtliche Betriebsphasen der Maschinenpresse zuverlässig ein über dem Umgebungsdruck liegender Basisdruck herrscht. In diesem Sinne kann der nach der vorliegenden Erfindung vorgesehene Hochdruck-Gasspeicher mit einem Bruchteil jener Baugröße auskommen, die der gemäß der
In Abhängigkeit von den spezifischen Gegebenheiten lässt sich die vorliegende Erfindung in verschiedensten konstruktiven Ausführungsvarianten technisch umsetzen. In diesem Sinne zeichnet sich eine erste bevorzugte Weiterbildung der vorliegenden Erfindung dadurch aus, dass der Druckfluidraum - bevorzugt zentral - innerhalb der Kolbeneinheit angeordnet ist, und zwar dergestalt, dass er gegenüber der zylindrischen Außenfläche eines in ihn mehr oder weniger tief eindringenden Tauchrohres, das mit dem Hochdruck-Gasspeicher in Verbindung steht, abgedichtet ist. Der Hydraulikraum kann dabei insbesondere von der vollständigen Stirnfläche der Kolbeneinheit begrenzt werden. Gemäß einer Abwandlung kann der Druckfluidraum (als zylindrischer Hohlraum) innerhalb eines an der Kolbeneinheit vorgesehenen Vorsprungs, welcher in den Hydraulikraum hineinragt, vorgesehen sein, wobei der Druckfluidraum durch ein in dem besagten zylindrischen Hohlraum dichtend geführtes Kolbenelement begrenzt ist. Der Druckfluidraum kann dabei ggf. ringförmig ausgeführt sein.Depending on the specific circumstances, the present invention can be technically implemented in a wide variety of design variants. In this sense, a first preferred embodiment of the present invention is characterized in that the pressure fluid chamber - preferably centrally - is disposed within the piston unit, in such a way that it with respect to the cylindrical outer surface of him more or less deeply penetrating immersion tube with the high-pressure gas storage is in communication, is sealed. The hydraulic space can be limited in particular by the complete end face of the piston unit. According to a modification, the pressure fluid space (as a cylindrical cavity) may be provided within a projection provided on the piston unit which projects into the hydraulic space, the pressure fluid space being delimited by a piston element sealingly guided in said cylindrical cavity. The pressure fluid space can optionally be designed annular.
Weiterhin besteht insoweit ein erheblicher Gestaltungsspielraum, als das in dem Hochdruck-Gasspeicher komprimierte Gas entweder direkt auf die Kolbeneinheit wirken kann, oder aber - durch Zwischenschaltung eines flüssigen Wirkmediums - mittelbar. Mit anderen Worten, in dem Druckfluidraum des Zylinderspeichers kann sich als Druckfluid entweder das Gas des Hochdruck-Gasspeichers befinden oder aber ein flüssiges Druckfluid, welches der Übertragung des in dem Hochdruck-Gasspeicher herrschenden Drucks auf den Druckfluidraum und der entsprechenden Beaufschlagung der Kolbeneinheit dient.Furthermore, there is a considerable scope for design insofar as the gas compressed in the high-pressure gas reservoir acts either directly on the piston unit can, or - by interposition of a liquid active medium - indirectly. In other words, either the gas of the high-pressure gas reservoir can be in the pressure fluid chamber of the cylinder reservoir, or a liquid pressure fluid which serves to transmit the pressure prevailing in the high-pressure gas reservoir to the pressurized fluid chamber and the corresponding pressurization of the piston unit.
Die anspruchsgemäße Angabe, wonach der die Kolbeneinheit des Zylinderspeichers beaufschlagende Druckfluidraum mit einem Hochdruck-Gasspeicher in Verbindung steht, darf im Übrigen nicht dahingehend verstanden werden, dass es sich bei dem Druckfluidraum und dem Hochdruck-Gasspeicher um zwei räumlich abgegrenzte Volumina handelt. Vielmehr ist eine konstruktive Umsetzung der vorliegenden Erfindung durchaus auch dergestalt möglich, dass der Druckfluidraum innerhalb des Zylinderspeichers auf der funktional dem Hydraulikraum abgewandten Seite der Kolbeneinheit - ggf. in dieser räumlich untergebracht - vorgesehen ist und zugleich das Volumen des Hochdruck-Gasspeichers (oder zumindest einen Teil hiervon) bildet bzw. mit diesem einen gemeinsamen gasgefüllten Hohlraum bildet. Insoweit ist - wegen baulicher Details - auf die Erläuterung eines der in der Zeichnung veranschaulichten Ausführungsbeispiele zu verweisen.The claim according to which the pressurized fluid chamber acting upon the piston unit of the cylinder reservoir is associated with a high-pressure gas accumulator may not otherwise be understood to mean that the pressure fluid chamber and the high-pressure gas accumulator are two spatially delimited volumes. Rather, a constructive implementation of the present invention is also quite possible in such a way that the pressure fluid space within the cylinder memory on the side facing away from the hydraulic chamber of the piston unit - possibly accommodated in this spatially - is provided and at the same time the volume of the high-pressure gas storage (or at least one Part thereof) forms or forms with this a common gas-filled cavity. In that regard - due to structural details - to refer to the explanation of one of the illustrated in the drawings embodiments.
Gemäß einer wiederum anderen bevorzugten Weiterbildung der vorliegenden Erfindung bedient der Hochdruck-Gasspeicher noch eine weitere Funktion der erfindungsgemäßen Maschinenpresse, namentlich indem er mit einem Feder-Gasspeicher identisch ist, welcher einen Rückhub-Arbeitsraum der zugeordneten Antriebseinheit beaufschlagt. Durch eine solche Integration mehrerer Funktionen in eine einzige bauliche Komponente des Antriebssystems lässt sich nicht nur - im Sinne eines besonders kompakten Antriebssystems - der erforderliche Platzbedarf reduzieren; vielmehr lassen sich auf diese Weise auch Kosten einsparen.According to yet another preferred embodiment of the present invention, the high pressure gas storage operates Yet another function of the machine press according to the invention, namely by being identical to a spring gas storage, which acts on a return stroke working space of the associated drive unit. Such integration of multiple functions in a single structural component of the drive system not only - in the sense of a particularly compact drive system - can reduce the space required; rather, costs can be saved in this way.
Im Folgenden wird die vorliegende Erfindung anhand von vier in der Zeichnung beispielhaft, mehr oder weniger schematisch veranschaulichten hydraulischen Antriebseinheiten, wie sie Bestandteil bevorzugter Ausführungsformen erfindungsgemäßer Maschinenpressen sein können, erläutert. Dabei zeigt

Die Zeichnung verzichtet darauf, die Maschinenpresse als ganzes abzubilden, und beschränkt sich auf die Widergabe der für die vorliegende Erfindung maßgeblichen, sich auf das jeweilige Antriebssystem beziehenden Aspekte. So können die Maschinenpressen, für die die nachstehend näher erläuterten Ausführungsbeispiele der Antriebssysteme bestimmt sind, hinsichtlich ihres grundsätzlichen Aufbaus insbesondere dem Stand der Technik (vgl. z.B.
Das auf den oberen Werkzeugträger der Maschinenpresse, um dessen abwärts gerichtete Bewegung zu bewirken, wirkende geschlossene hydraulische Antriebssystem umfasst jeweils mindestens eine hydraulische Antriebseinheit 1. Typischerweise umfasst das betreffende Antriebssystem jeder Maschinenpresse jeweils zwei der veranschaulichten Antriebseinheiten, so dass in der folgenden Beschreibung hierauf abgestellt wird.The closed hydraulic drive system acting on the upper tool carrier of the machine press to effect its downward movement comprises at least one hydraulic drive unit 1. Typically, the respective drive system of each machine press comprises two of the illustrated drive units, so that will be described in the following description ,
Jede der beiden Antriebseinheiten 1 umfasst ihrerseits eine hydraulische Zylinder-Kolben-Einheit 2 - es können ggf. auch mehrere Zylinder-Kolben-Einheiten 2 vorgesehen sein - mit einem Zylinder 3 und einem darin geführten Kolben 4, dessen Kolbenstange 5 mit dem oberen Werkzeugträger der Maschinenpresse fest verbunden ist, und ein die hydraulische Zylinder-Kolben-Einheit 2 beaufschlagendes Hydraulikaggregat 6 mit einer durch einen (hinsichtlich der Drehrichtung umschaltbaren) Elektromotor 7 angetriebenen, als Reversierpumpe ausgeführten Hydraulikpumpe 8.Each of the two drive units 1 in turn comprises a hydraulic cylinder-piston unit 2 - it may optionally be provided more cylinder-piston units 2 - with a
Der obere Werkzeugträger ist mittels einer Federeinrichtung in seine obere Endlage vorgespannt. Die Federeinrichtung ist dergestalt in die hydraulischen Zylinder-Kolben-Einheiten 2 der beiden Antriebseinheiten 1 integriert, dass jeweils der Kolbenstangenarbeitsraum 9 der hydraulischen Zylinder-Kolben-Einheiten 2 hydraulisch mit einem zugeordneten, unter einer Gas-Vorspannung stehenden externen Druckspeicher 10 verbunden ist.The upper tool carrier is biased by means of a spring device in its upper end position. The spring device is integrated into the hydraulic cylinder-
Der Hydraulikantrieb der Maschinenpresse ist zwischen einem Eilgang und einem Pressgang umschaltbar. Dabei erfolgt - nachdem die aufwärts gerichtete Kraft der (vorstehend beschriebenen) Federeinrichtung ständig in einer solchen Höhe auf den oberen Werkzeugträger wirkt, dass dessen Gewicht und das aller mit ihm gekoppelten bewegbaren Komponenten der Maschinenpresse sowie die Schließkraft, welche durch den in den beiden hydraulischen Antriebseinheiten herrschenden Basisdruck impliziert wird (s.u.), überkompensiert und der obere Werkzeugträger in seine oberste Stellung vorgespannt wird - auch im Eilgang eine aktive Bewegung des oberen Werkzeugträgers durch den Hydraulikantrieb, nicht indessen eine freie Bewegung aufgrund der Schwerkraft. Erreicht wird dies, indem in die Kolben 4 der beiden hydraulischen Zylinder-Kolben-Einheiten 2, nämlich jeweils eine darin eingebrachte Bohrung 11 jeweils ein Hilfskolben 12 eintaucht. Näheres hierzu ist der
Für den Pressgang wird das Ventil 18 umgeschaltet, so dass das Hydraulikaggregat 6 parallel den Kolbenarbeitsraum 17 und den Hilfsarbeitsraum 15 beaufschlagt. Am Ende der Schließbewegung, d.h. typischerweise wenn der obere Werkzeugträger eine vorgegebene Position erreicht, wird die Förderung des Hydraulikaggregats 6 heruntergefahren und gestoppt, so dass der obere Werkzeugträger anhält. Das Werkzeug hält dann kurze Zeit inne, bevor der sog. "Dekompressionshub" einsetzt, d.h. das langsame, kontrollierte Abheben des oberen Werkzeugs und Öffnen der Presse über einen geringen Hub (z.B. 2-3 mm) durch Förderrichtungsumkehr des Hydraulikaggregats. Am Ende des Dekompressionshubes, d.h. wenn der hohe Druck in der Zylinder-Kolben-Einheit 2 zumindest im Wesentlichen abgebaut ist, werden das Ventil 18 und das Nachsaugventil 19 umgesteuert, so dass der Kolben 4 unter der Einwirkung der Federeinrichtung einfährt. Das Einfahren des Kolbens 4 erfolgt dabei im Eilgang kontrolliert (gebremst), indem der Hilfsarbeitsraum 15 über das weiterhin mit gegenüber dem Schließen der Presse umgekehrter Förderrichtung betriebene Hydraulikaggregat 6 kontrolliert und gesteuert entleert wird. Insoweit ist bei dieser hydraulischen Antriebseinheit die Förderleistung des Hydraulikaggregats 6 um- und einstellbar.For the pressing operation, the
Das Hydrauliksystem ist hermetisch abgeschlossen. Hierzu ist ein Vorratsbehälter 20 für die Hydraulikflüssigkeit vorgesehen, welcher einen volumenveränderlichen Hydraulikraum (Vorratsraum) 21 umfasst, wobei die maximale Volumendifferenz des Vorratsraumes 21 auf das Wechselvolumen der hydraulischen Zylinder-Kolben-Einheit 2 abgestimmt ist.The hydraulic system is hermetically sealed. For this purpose, a
Die Hydraulikflüssigkeit ist in dem Hydrauliksystem dergestalt eingespannt, dass in diesem ständig und überall - und somit insbesondere in dem Vorratsraum 21 - zumindest ein über dem Umgebungsdruck liegender Basisdruck herrscht. Bei sämtlichen Ausführungsbeispielen ist hierzu, in konstruktiver Umsetzung der vorliegenden Erfindung, der Vorratsbehälter 20 als Zylinderspeicher 22 mit einem durch einen Zylinder 23 und einer darin verschiebbar geführten Kolbeneinheit 24 begrenzten Vorratsraum (Hydraulikraum) 21 ausgeführt. Die Kolbeneinheit 24 wird auf ihrer dem Hydraulikraum 21 funktional gegenüberliegenden Seite von einem Druckfluidraum 25 beaufschlagt. Dieser steht seinerseits mit einem Hochdruck-Gasspeicher 26 in Verbindung. Die Wirkfläche 27 des Druckfluidraumes 25 an der Kolbeneinheit 24 ist klein gegenüber der Wirkfläche 28 des Hydraulikraumes 21 an der Kolbeneinheit 24.The hydraulic fluid is clamped in the hydraulic system in such a way that it constantly and everywhere - and thus in particular in the reservoir 21 - at least one above ambient pressure base pressure prevails.

Es ist zur Klarstellung darauf hinzuweisen, dass aus der Veranschaulichung der vorstehend erläuterten Ausführungsbeispiele mit diversen Detailmerkmalen keinesfalls auf eine dementsprechend beschränkte Offenbarung der vorliegenden Erfindung geschlossen werden darf, und zwar schon gar nicht dergestalt, dass die jeweiligen Einzelmerkmale jeweils nur einer solchen Kombination miteinander offenbart seien. Vielmehr sind auch andere Detailmerkmale und/oder andere Merkmalskombinationen von der vorliegenden Erfindung erfasst. Beispielsweise ist die spezifische (hydropneumatische) Ausführung der Einrichtung für den Rückhub des oberen Werkzeugträgers in keiner Weise zwingend. Vielmehr können sämtliche bekannten sonstigen, beispielsweise hydraulisch, mechanisch, elektrisch pneumatisch oder auf sonstige Weise funktionierenden Rückhubeinrichtungen vorgesehen sein. Ebenso wenig ist zwingend, dass der obere Werkzeugträger der Maschinenpresse überhaupt mit zwei unterschiedlichen Geschwindigkeiten, d.h. in einem Eingang und einem Pressgang abgesenkt werden kann, und falls ja, dass hierfür ein kombinierter Hydraulikzylinder gemäß der veranschaulichten Bauweise dient. Diverse sonstige bekannte Ausgestaltungen, die eine zweistufige Absenkbewegung des oberen Werkzeugträgers zulassen, sind ersichtlich ebenfalls im Rahmen der vorliegenden Erfindung einsetzbar.It is to be pointed out for the sake of clarification that from the illustration of the above-explained exemplary embodiments with various detail features, a correspondingly limited disclosure of the present invention may under no circumstances be concluded, certainly not in such a way that the respective individual features of only one such combination are disclosed to one another , Rather, other detail features and / or other feature combinations are covered by the present invention. For example, the specific (hydropneumatic) design of the device for the return stroke of the upper tool carrier is in no way mandatory. Rather, all known other, for example, hydraulically, mechanically, electrically pneumatically or otherwise be provided working return devices. Nor is it imperative that the upper tool carrier of the machine press can be lowered at all at two different speeds, ie in an input and a press gear, and if so, that a combined hydraulic cylinder according to the illustrated construction is used for this purpose. Various other known embodiments, which allow a two-stage lowering movement of the upper tool carrier, can also be used in the context of the present invention.
