- the press has eleven in the press longitudinal direction successively arranged rows of pressing cylinders, each row of turn four pressing cylinders composed.
- a constant problem is the inspection or maintenance of the individual components of the cycle press. This applies in particular to the press cylinder. For example, for maintenance work on the cylinder interior, it was generally necessary to completely remove the press cylinders from the press. Since such measures are relatively complex and can lead to a long standstill of the entire press, alternative solutions have been proposed in which the piston can be removed from the cylinder housing with built-in cylinder (see. DE 10 2004 033 484 B3 ).
- the invention has for its object to provide a cycle press, in particular short-cycle press for the production and / or coating of plate-shaped materials, in particular wood-based panels, which is constructed easy to install and maintain even with a design for high compression pressures.
- the invention teaches in a generic clock press of the type described above, that the press cylinders are fastened with engaging in recesses of the press frame frame bolts to the press frame.
- the press cylinders are biased with the frame bolts against the press frame.
- the invention is based on the finding that the press cylinder can be easily and reliably attached to the press frame when working with separate frame bolts, which (releasably) are inserted in suitable recesses of the press frame, so that the press cylinder against this frame bolt and so that it can be clamped against the press frame.

- slot-like recesses and / or other diameter reductions of the ends of the frame bolt causes the frame bolts - after loosening the clamping screws - relatively easy by appropriate tilting and / or twisting from the recesses and then between the press frame, z. B. away up, remove. Consequently, on the one hand a particularly reliable fixing of the cylinder to the press frame and on the other hand this fixation can be easily solved for maintenance purposes, so that a cylinder expansion with relatively simple measures is possible.
- the cylinders or their cylinder housings are themselves provided in a manner known per se in cross-section or in plan view with lateral flattenings, so that the cylinders have a larger diameter in cross-section in one direction than in the other direction oriented transversely thereto. Consequently, the cylinder housings can be fixed on the one hand place under the frame and on the other hand rotate for disassembly by 90 °, so that the cylinder housing or the entire cylinder can then be removed between two adjacent press frame up out of the press.
- the frame bolts can be used as solid frame bolts, z. B. as a steel bolt, be formed. Alternatively, however, the frame bolts may also be formed as tubular bolts and consequently pipe pieces. In both cases, it may be advantageous to bolt the frame bolts with the clamping screws with the interposition of additional power distribution plates.
- the force distribution plates can either be adapted to the shape of the bolts or deform themselves during the fixation. In any case, can be made available for the screws or nuts on the Kraftverteilplatten proper support surfaces, especially when working with frame bolts, which have a round diameter.
- the cylinders are placed in the frame windows under the press frame. It is therefore within the scope of the invention that the cylinders themselves do not engage with their cylinder housings in the space between the press frame. This embodiment is particularly useful when the cylinders are designed for very high pressing forces. For it is particularly preferred within the scope of the invention to provide a press which is designed for a specific pressing pressure of more than 600 N / cm 2 , more preferably 700 N / cm 2 and more.

- the press cylinders are usually designed as a single-acting hydraulic cylinder, which can be applied only in one direction pressing forces. To open the press additional return cylinders are usually provided. Basically, however, it is also within the scope of the invention, the press cylinder as a double-acting hydraulic cylinder, z. B. differential cylinder, form, so that then possibly can be dispensed with retraction cylinder.
- the invention includes of course also sub-piston presses, where the pressing cylinder work on the lower press plate.
- the figures show a short-cycle press as Amsterdamtagenpresse for the production or for the coating of wood-based panels.

- Fig. 7 The insulation is therefore not attached to the end face of the piston 9, but they are placed in the course of assembly in a suitable manner on top of the upper press plate 5 and then braced in the course of attachment of the piston 9 on the press plate 5 between the piston end and press plate.
- FIG. 6 and 7 show beyond that in addition to the mounting plates 17 and the insulation plates 23 also centering plates 26 are provided, which also engage in fastening grooves 18. These centering plates 26 are also fastened with fastening screws 27 on the press plates 5. These centering plates 26 serve for optimum positioning of the press plate 5 both in the longitudinal direction and in the transverse direction. This results in particular from Fig. 7 , because there it can be seen that in each case two centering plates 26 are provided for the positioning in the transverse direction on the one hand and for the positioning in the longitudinal direction on the other hand.
- FIG. 6 shows Fig. 6 in that locking cylinders 28 are fastened to the cylinder housings 8 of the press cylinders 7 on the underside or end.
- These locking brackets 28 serve to lock the piston 9 in the retracted position or in another position. This lock is required in order to expand the entire pressure cylinder, ie cylinder housing 8 together with cylinder piston 9 after releasing the hot plate from the press without the piston 9 falling down out of the cylinder housing.
- Particularly advantageous is the fact that the locking brackets 28 can remain "permanently" mounted on the cylinder housing.
- the press is additionally equipped with retraction cylinders 31.

Die Presszylinder, welche auch als Zylinderkolbenanordnungen bezeichnet werden, sind in der Regel in mehreren in Pressenlängsrichtung hintereinander angeordneten Reihen angeordnet, wobei jede Reihe eine Mehrzahl von Zylinderkolbenanordnungen aufweist. Die Presszylinder sind bevorzugt als Hydraulikzylinder ausgebildet. Eine solche Presse, die auch als Einetagenpresse bezeichnet wird, arbeitet taktweise, d. h. das Ausgangsmaterial wird taktweise in die Presse (zwischen oberer Pressenplatte und unterer Pressenplatte) eingeführt und die Presse öffnet und schließt taktweise. Die das Pressengestellt bildenden Pressenrahmen sind z. B. aus Stahlblechzuschnitten in Fensterbauweise und folglich mit Rahmenfenstern ausgebildet.The invention relates to a cycle press, in particular short-cycle press, for the production and / or coating of plate-shaped materials, in particular wood-based panels, with a press frame, with several aligned in the press longitudinal direction press frame and with an upper press plate and a lower press plate, wherein the upper press plate or the lower Press plate are loaded with pressing cylinders, which are supported on the press frame. - The press plates are designed as heatable press plates and consequently hot plates. The press cylinders, which are also referred to as cylinder piston arrangements, are generally arranged in a plurality of rows arranged one behind the other in the press longitudinal direction, each row having a plurality of cylinder piston arrangements. The pressing cylinders are preferably designed as hydraulic cylinders. Such a press, which is also referred to as a one-floor press, works in cycles, d. H. the starting material is fed cyclically into the press (between upper press plate and lower press plate) and the press opens and closes intermittently. The press frame forming press frame are z. B. made of sheet steel blanks in window construction and consequently formed with frame windows.
Taktpressen der eingangs beschriebenen Art sind in verschiedensten Ausführungsformen bekannt (vgl. z. B.
Ein ständiges Problem bereitet die Inspektion bzw. Wartung der einzelnen Komponenten der Taktpresse. Dieses gilt insbesondere für die Presszylinder. So war es beispielsweise für Wartungsarbeiten am Zylinderinnenraum in der Regel erforderlich, die Presszylinder vollständig aus der Presse auszubauen. Da derartige Maßnahmen verhältnismäßig aufwändig sind und zu einem langen Stillstand der gesamten Presse führen können, wurden Alternativlösungen vorgeschlagen, bei welchen die Kolben bei eingebautem Zylinder aus dem Zylindergehäuse ausgebaut werden können (vgl.
Die aus der Praxis bekannten Taktpressen haben sich grundsätzlich bewährt. Sie sind jedoch weiterentwicklungsfähig. Es besteht insbesondere das Problem, dass die Konstruktion bei der Auslegung der Presse für besonders hohe Pressdrücke so aufwändig wird, dass Reparatur- und Wartungsarbeiten nur noch mit enormem Aufwand möglich sind. ― Hier setzt die Erfindung ein.The known from practice tact presses have basically proven. They are, however, capable of further development. In particular, there is the problem that the construction in the design of the press for particularly high compression pressures becomes so complex that repair and maintenance work is possible only with enormous effort. - This is where the invention starts.
Der Erfindung liegt die Aufgabe zugrunde, eine Taktpresse, insbesondere Kurztaktpresse für die Herstellung und/oder Beschichtung von plattenförmigen Werkstoffen, insbesondere Holzwerkstoffplatten, zu schaffen, welche auch bei einer Auslegung für hohe Pressdrücke montage- und wartungsfreundlich aufgebaut ist.The invention has for its object to provide a cycle press, in particular short-cycle press for the production and / or coating of plate-shaped materials, in particular wood-based panels, which is constructed easy to install and maintain even with a design for high compression pressures.
Zur Lösung dieser Aufgabe lehrt die Erfindung bei einer gattungsgemäßen Taktpresse der eingangs beschriebenen Art, dass die Presszylinder mit in Ausnehmungen der Pressenrahmen eingreifenden Rahmenbolzen an den Pressenrahmen befestigt sind. Bevorzugt sind die Presszylinder mit den Rahmenbolzen gegen die Pressenrahmen vorgespannt.To solve this problem, the invention teaches in a generic clock press of the type described above, that the press cylinders are fastened with engaging in recesses of the press frame frame bolts to the press frame. Preferably, the press cylinders are biased with the frame bolts against the press frame.
Die Erfindung geht dabei von der Erkenntnis aus, dass sich die Presszylinder einfach und zuverlässig an den Pressenrahmen befestigen lassen, wenn mit separaten Rahmenbolzen gearbeitet wird, welche (lösbar) in geeigneter Ausnehmungen der Pressenrahmen eingesetzt werden, so dass die Presszylinder dann gegen diese Rahmenbolzen und damit gegen die Pressenrahmen verspannt werden können. Jeder einzelne Rahmenbolzen greift dabei besonders bevorzugt in zwei fluchtende Ausnehmungen zweier unmittelbar benachbarter Pressenrahmen ein, wobei an diesen beiden benachbarten Pressenrahmen gemeinsam ein Presszylinder abgestützt ist. Auf diese Weise lassen sich die Presszylinder einfach gegen die Pressenrahmen vorspannen, so dass eine einwandfreie Zylinderbefestigung realisiert ist. Dieses ist insbesondere dann vorteilhaft, wenn die Presse für sehr hohe Pressdrücke ausgelegt ist. Denn auf die erfindungsgemäße Weise gelingt eine einwandfreie Befestigung von Presszylindern mit hohem Gewicht, großem Durchmesser und großer Wandstärke.The invention is based on the finding that the press cylinder can be easily and reliably attached to the press frame when working with separate frame bolts, which (releasably) are inserted in suitable recesses of the press frame, so that the press cylinder against this frame bolt and so that it can be clamped against the press frame. Each individual frame bolt engages particularly preferably in two aligned recesses of two immediately adjacent press frame, wherein a pressing cylinder is supported together on these two adjacent press frame. In this way, the press cylinder can easily bias against the press frame, so that a perfect cylinder mounting is realized. This is particularly advantageous if the press is designed for very high compression pressures. Because in the inventive way succeeds a perfect attachment of pressing cylinders with high weight, large diameter and large wall thickness.
Die Presszylinder sind vorzugsweise mittels mehrerer in die Zylindergehäuse eingeschraubter und die Rahmenbolzen durchgreifender Spannschrauben gegen die Pressenrahmen vorgespannt. So können die Zylindergehäuse beispielsweise endseitig mehrere Gewinde, z. B. über den Umfang vier verteilte Gewinde aufweisen, in welche jeweils eine Spannschraube bzw. eine Spannstange eingreift. Bevorzugt wird jeder Zylinder mit mehreren Rahmenbolzen befestigt, z. B. mit zwei Rahmenbolzen, wobei jedem Rahmenbolzen wiederum mehrere Spannschrauben, z. B. jeweils zwei Spannschrauben zugeordnet sein können.The pressing cylinders are preferably biased by means of several screwed into the cylinder housing and the frame bolts by cross clamping screws against the press frame. For example, the cylinder housing, the end more thread, z. B. over the circumference four distributed threads, in which each engages a clamping screw or a tie rod. Preferably, each cylinder is fastened with a plurality of frame bolts, z. B. with two frame bolts, with each frame bolt turn several clamping screws, z. B. in each case two clamping screws can be assigned.
In besonders bevorzugter Weiterbildung der Erfindung ist vorgesehen, dass die Rahmenbolzen und die Ausnehmungen in den Pressenrahmen derart aufeinander abgestimmt sind, dass die Rahmenbolzen zwischen den betreffenden beiden Pressenrahmen ausbaubar sind. Dazu können die Ausnehmungen z. B. als langlochartige Ausnehmungen ausgebildet sein, so dass sie z. B. in der vertikalen Richtung eine größere Erstreckung aufweisen als der Durchmesser der Rahmenbolzen selbst. Alternativ oder ergänzend können die Enden der Rahmenbolzen oder zumindest ein Ende mit einer Durchmesserreduzierung versehen sein. Bei dieser Durchmesserreduzierung kann es sich z. B. um eine Abschrägung des Rahmenbolzens an einem stirnseitigen Ende handeln. Diese Ausgestaltung mit einerseits langlochartigen Ausnehmungen und/oder andererseits Durchmesserreduzierungen der Enden der Rahmenbolzen führt dazu, dass sich die Rahmenbolzen ― nach dem Lösen der Spannschrauben ― verhältnismäßig einfach durch entsprechendes Verkippen und/oder Verdrehen aus den Ausnehmungen entfernen und dann zwischen den Pressenrahmen, z. B. nach oben weg, entfernen lassen. Es gelingt folglich einerseits eine besonders zuverlässige Fixierung der Zylinder an den Pressenrahmen und andererseits lässt sich diese Fixierung einfach zu Wartungszwecken lösen, so dass ein Zylinderausbau mit verhältnismäßig einfachen Maßnahmen möglich wird.In a particularly preferred embodiment of the invention, it is provided that the frame bolts and the recesses in the press frame are matched to one another such that the frame bolts between the respective two press frame are removable. For this purpose, the recesses z. B. be formed as slot-like recesses so that they z. B. in the vertical direction have a greater extent than the diameter of the frame bolts themselves. Alternatively or additionally, the ends of the frame bolts or at least one end may be provided with a diameter reduction. With this diameter reduction, it may, for. B. may be a bevel of the frame bolt at a front end. This embodiment, on the one hand slot-like recesses and / or other diameter reductions of the ends of the frame bolt causes the frame bolts - after loosening the clamping screws - relatively easy by appropriate tilting and / or twisting from the recesses and then between the press frame, z. B. away up, remove. Consequently, on the one hand a particularly reliable fixing of the cylinder to the press frame and on the other hand this fixation can be easily solved for maintenance purposes, so that a cylinder expansion with relatively simple measures is possible.
Dabei sind die Zylinder bzw. deren Zylindergehäuse selbst in an sich bekannter Weise im Querschnitt bzw. in der Draufsicht mit seitlichen Abflachungen versehen, so dass die Zylinder im Querschnitt in der einen Richtung einen größeren Durchmesser aufweisen, als in der quer dazu orientierten anderen Richtung. Die Zylindergehäuse lassen sich folglich einerseits zur Fixierung unter die Rahmen unterstellen und andererseits zur Demontage um 90° drehen, so dass die Zylindergehäuse bzw. die gesamten Zylinder dann zwischen zwei benachbarten Pressenrahmen nach oben aus der Presse entfernt werden können.The cylinders or their cylinder housings are themselves provided in a manner known per se in cross-section or in plan view with lateral flattenings, so that the cylinders have a larger diameter in cross-section in one direction than in the other direction oriented transversely thereto. Consequently, the cylinder housings can be fixed on the one hand place under the frame and on the other hand rotate for disassembly by 90 °, so that the cylinder housing or the entire cylinder can then be removed between two adjacent press frame up out of the press.
Die Rahmenbolzen können als massive Rahmenbolzen, z. B. als Stahlbolzen, ausgebildet sein. Alternativ können die Rahmenbolzen aber auch als rohrförmige Bolzen und folglich Rohrstücke ausgebildet sein. In beiden Fällen kann es vorteilhaft sein, die Rahmenbolzen mit den Spannschrauben unter Zwischenschaltung zusätzlicher Kraftverteilplatten zu verschrauben. Die Kraftverteilplatten können entweder an die Form der Schraubenbolzen angepasst sein oder sich im Zuge der Fixierung selbst verformen. Jedenfalls können über die Kraftverteilplatten einwandfreie Auflageflächen für die Schrauben bzw. Muttern zur Verfügung gestellt werden, und zwar insbesondere dann, wenn mit Rahmenbolzen gearbeitet wird, die einen runden Durchmesser aufweisen.The frame bolts can be used as solid frame bolts, z. B. as a steel bolt, be formed. Alternatively, however, the frame bolts may also be formed as tubular bolts and consequently pipe pieces. In both cases, it may be advantageous to bolt the frame bolts with the clamping screws with the interposition of additional power distribution plates. The force distribution plates can either be adapted to the shape of the bolts or deform themselves during the fixation. In any case, can be made available for the screws or nuts on the Kraftverteilplatten proper support surfaces, especially when working with frame bolts, which have a round diameter.
Besonders bevorzugt sind die Zylinder in den Rahmenfenstern unter die Pressenrahmen untergestellt. Es liegt folglich im Rahmen der Erfindung, dass die Zylinder selbst nicht mit ihren Zylindergehäusen in den Zwischenraum zwischen den Pressenrahmen eingreifen. Diese Ausführungsform ist insbesondere dann zweckmäßig, wenn die Zylinder für sehr hohe Presskräfte ausgelegt werden. Denn besonders bevorzugt wird im Rahmen der Erfindung eine Presse geschaffen, die für einen spezifischen Pressdruck von mehr als 600 N/cm2, besonders bevorzugt 700 N/cm2 und mehr ausgelegt ist.Particularly preferably, the cylinders are placed in the frame windows under the press frame. It is therefore within the scope of the invention that the cylinders themselves do not engage with their cylinder housings in the space between the press frame. This embodiment is particularly useful when the cylinders are designed for very high pressing forces. For it is particularly preferred within the scope of the invention to provide a press which is designed for a specific pressing pressure of more than 600 N / cm 2 , more preferably 700 N / cm 2 and more.
Nach einem weiteren Vorschlag ist vorgesehen, dass die Presse zumindest zwei Hydrauliktanks aufweist, die nicht zentriert auf das Pressengestell aufgesetzt sind, sondern bevorzugt in Seitenbereichen der Presse und folglich seitlich versetzt zur senkrechten Mittelebene der Presse angeordnet sind, besonders bevorzugt seitlich versetzt zu den Presszylindern. Eine solche Ausführungsform hat gegenüber einer herkömmlichen Ausführungsform mit einem zentralen Hydrauliktank den Vorteil, dass der Bauraum oberhalb der Zylinder frei zugänglich ist, sodass die Presszylinder insgesamt nach oben aus dem Pressengestell entfernt werden können. Dieses kann beispielsweise mit ohnehin vorhandenen Hebezeugen, z. B. einen Hallenkran oder Deckenkran erfolgen. Es liegt jedoch auch im Rahmen der Erfindung, dass eine spezielle Hebevorrichtung auf das Pressengestell aufgesetzt wird oder im Bereich der Presse montiert wird. Jedenfalls wird im Rahmen der Erfindung eine Konstruktion realisiert, bei welcher sich die Presszylinder ohne weiteres vollständig aus der Presse ausbauen lassen, und zwar vorzugsweise, indem die Presszylinder nach Lösen der Fixierung und nach Lösen der Befestigung von der jeweiligen Heizplatte nach oben aus dem Pressengestell entfernt werden.According to another proposal, it is provided that the press has at least two hydraulic tanks which are not centered on the press frame, but preferably in lateral areas of the press and thus laterally offset from the vertical center plane of the press are arranged, particularly preferably laterally offset to the pressing cylinders. Such an embodiment has over a conventional embodiment with a central hydraulic tank the advantage that the space above the cylinder is freely accessible, so that the pressing cylinder can be removed altogether upwards out of the press frame. This can, for example, with already existing hoists, z. B. a hall crane or overhead crane done. However, it is also within the scope of the invention that a special lifting device is placed on the press frame or mounted in the press. Anyway, in the context of the invention, a construction is realized in which the pressing cylinder can be easily completely removed from the press, preferably by removing the press cylinder after loosening the fixation and after loosening the attachment of the respective heating plate up out of the press frame become.
Es liegt grundsätzlich im Rahmen der Erfindung, die Hydrauliktanks oben auf die Pressenrahmen aufzusetzen. Besonders bevorzugt werden die Hydrauliktanks jedoch nicht unmittelbar auf die Pressenrahmen aufgesetzt, sondern auf Verbindungsbolzen oder -stangen, welche die Pressenrahmen untereinander verbinden. Denn besonders bevorzugt werden die einzelnen Pressenrahmen mit in Pressenlängsrichtung verlaufenden Verbindungsbolzen oder -stangen miteinander verbunden. Auf diese Verbindungsbolzen können die Hydrauliktanks mit geeigneten Tankträgern aufgesetzt werden, so dass eine Entlastung der einzelnen Rahmenbleche gewährleistet und eine Beschädigung vermieden wird.It is basically within the scope of the invention to set up the hydraulic tanks on top of the press frame. However, the hydraulic tanks are not particularly preferably placed directly on the press frame, but on connecting bolts or rods which connect the press frame with each other. For particularly preferably, the individual press frame are connected to each other with extending in the press longitudinal direction connecting bolt or rods. On these connecting bolts, the hydraulic tanks can be placed with suitable tank carriers, so that a relief of the individual frame plates ensures and damage is avoided.
Die Presse ist bevorzugt als Vielkolbenpresse ausgebildet. Das bedeutet, dass die einzelnen Presszylinderreihen nicht nur lediglich zwei Presszylinder aufweisen, sondern zumindest drei, besonders bevorzugt zumindest vier Presszylinder. In Pressenlängsrichtung können dann z. B. zehn Reihen von Presszylindern oder mehr hintereinander angeordnet sein. Eine solche Vielkolbenpresse mit 40 Presszylindern oder mehr erlaubt eine variable Anpassung der Presse an unterschiedlich zu verpressende Plattenformate. Dazu können die vielen Presszylinder auch unterschiedlich ansteuerbar sein. So können beispielsweise mehrere unabhängig von einander einstellbare Hydrauliksysteme bzw. Presssysteme realisiert sein, z. B. sechs unabhängig voneinander einstellbare Presssysteme oder mehr.The press is preferably designed as a multi-piston press. This means that the individual press cylinder rows not only have two press cylinders, but at least three, more preferably at least four press cylinders. In the press longitudinal direction z. B. ten rows of press cylinders or more can be arranged one behind the other. Such a multi-piston press with 40 press cylinders or more allows a variable adjustment of the press to different to be pressed plate formats. For this purpose, the many press cylinders can also be controlled differently. For example, can be implemented independently of each other adjustable hydraulic systems or pressing systems, for. B. six independently adjustable pressing systems or more.
Insgesamt wird eine Kurztaktpresse geschaffen, welche für besonders hohe Pressdrücke von 700 N/cm2 und mehr ausgelegt ist. Die Presse ist insbesondere für die Kurztaktbeschichtung von Holzwerkstoffplatten mit z. B. Dekorpapieren geeignet. Diese Kurztaktbeschichtung kommt beispielsweise bei der Herstellung von Laminatböden, Wandpanelen, Möbeln oder Türen zum Einsatz.Overall, a short-cycle press is created, which is designed for particularly high compression pressures of 700 N / cm 2 and more. The press is especially for the short-cycle coating of wood-based panels with z. B. decorative papers suitable. This short-cycle coating is used, for example, in the production of laminate flooring, wall panels, furniture or doors.
Besonders bevorzugt ist die erfindungsgemäße Presse als Oberkolbenpresse ausgeführt, d. h. die Presszylinder arbeiten auf die obere Heizplatte, während die untere Heizplatte (ortsfest) auf den unteren Querholmen der Pressenrahmen aufliegt. Die Presszylinder sind dabei in der Regel als einfach wirkende Hydraulikzylinder ausgebildet, mit denen sich lediglich Presskräfte in einer Richtung aufbringen lassen. Zum Öffnen der Presse sind in der Regel zusätzliche Rückzugzylinder vorgesehen. Grundsätzlich liegt es jedoch auch im Rahmen der Erfindung, die Presszylinder als doppelt wirkende Hydraulikzylinder, z. B. Differentialzylinder, auszubilden, so dass dann ggf. auf Rückzugzylinder verzichtet werden kann. Im Übrigen umfasst die Erfindung selbstverständlich auch Unterkolbenpressen, bei denen die Presszylinder auf die untere Pressenplatte arbeiten.Particularly preferably, the press according to the invention is designed as an upper-piston press, ie the pressing cylinder work on the upper heating plate, while the lower heating plate (stationary) rests on the lower crossbars of the press frame. The press cylinders are usually designed as a single-acting hydraulic cylinder, which can be applied only in one direction pressing forces. To open the press additional return cylinders are usually provided. Basically, however, it is also within the scope of the invention, the press cylinder as a double-acting hydraulic cylinder, z. B. differential cylinder, form, so that then possibly can be dispensed with retraction cylinder. Incidentally, the invention includes of course also sub-piston presses, where the pressing cylinder work on the lower press plate.

Die Pressenrahmen 2 sind im Ausführungsbeispiel aus Stahlblechzuschnitten gefertigt, und zwar in "Fensterbauweise", d. h. die einzelnen Pressenrahmen 2 weisen jeweils ein Rahmenfenster 3 auf, welches oben vom oberen Querholm 2a und unten vom unteren Querholm 2b begrenzt wird. Die einzelnen Pressenrahmen 2 sind mit Verbindungsstangen 4 miteinander verbunden, welche in Pressenlängsrichtung orientiert sind. Zwischen die Rahmen 2 sind dazu Distanzrohre auf die Verbindungsstangen 4 aufgesteckt. Die Presse weist eine obere Pressenplatte 5 und eine untere Pressenplatte 6 auf. Diese Pressenplatten 5, 6 sind als beheizte Pressenplatten und folglich Heizplatten ausgebildet. Die Presse ist in einer Vielzahl von Presszylindern 7 ausgerüstet, welche im Ausführungsbeispiel als einfach wirkende Hydraulikzylinder 7 ausgebildet sind. Jeder Presszylinder 7 weist einerseits ein Zylindergehäuse 8 und andererseits einen Zylinderkolben 9 auf. Die Presse ist als Oberkolbenpresse ausgeführt, d. h. die Presszylinder 7 sind mit Ihrem Zylinderkolben 9 an die (bewegliche) obere Pressenplatte 5 angeschlossen, während die untere Pressenplatte 6 im Wesentlichen ortsfest auf den unteren Querholmen 2b der Pressenrahmen 2 aufliegt. Die Presszylinder 7 sind in die Rahmenfenster 3 eingestellt und unter die oberen Querholme 2a der Pressenrahmen 2 untergestellt, d. h. sie stützen sich im Zuge der Aufbringung der Presskraft mit ihren oberen stirnseitigen Enden an den oberen Querholmen 2a der Pressenrahmen ab (vgl.

Die Rahmenbolzen 10 sind im Ausführungsbeispiel als massive Bolzen ausgebildet. Die Länge der Bolzen entspricht dem äußeren Abstand zweier benachbarter Pressenrahmen. Die Rahmenbolzen 10 sind mit den Spannschrauben 12 unter Zwischenschaltung von Kraftverteilplatten 14 verschraubt. Diese gewährleisten eine einwandfreie Abstützfläche der Muttern bzw. Spannschrauben auf den Rahmenbolzen 10, welche im Ausführungsbeispiel einen runden Querschnitt aufweisen. An den Rahmenbolzen 10 sind Sicherungen 32 in Form von Sicherungsplatten befestigt, z. B. mittels Schrauben. Diese dienen der Sicherung des Bolzens 10 in axialer Richtung, so dass der Bolzen 10 im montierten Zustand nicht aus den Ausnehmungen gleiten kann. Dazu sind die Platten 32 breiter als die Ausnehmungen 11. Sie liegen innen gegen die Pressenrahmen 2 an. Zum Entfernen der Rahmenbolzen 10 müssen dann zuvor die Platten 32 gelöst werden.The
Um die Presszylinder 7 zum Zwecke der Wartung oder zum Zwecke des Austauschs einfach nach oben aus der Presse ausbauen zu können, wird bei dem dargestellten Ausführungsbeispiel auf den sonst üblichen zentralen Hydrauliktank verzichtet. Stattdessen ist gleichsam ein Doppeltank realisiert. So zeigt
