Definitions
- the invention relates to a press for pressing plate-shaped workpieces with at least two pressure chambers the closer in the preamble of claim 1 marked art.
- each pressure chamber it is necessary for each pressure chamber to have one separate lifting table, i.e. separate pressure bar and associated lifting cylinder, i.e. Pressure cylinder with piston, be assigned.
- the invention is therefore based on the object of a press of the generic type in which two create each other neighboring pressure rooms alternately opened and can be closed.
- Lifting table has a double function in relation to the two press rooms to, because in the first cycle he presses the material to be pressed a pressure chamber against the first fixed press table, the remote pressure room is open, and in the second Working cycle is the material to be pressed in the second pressure chamber against the second fixed press table pressed while the first Print room is open.
- the lifting cylinder immediately above or below the Lift table adjacent fixed press table what shortens the path of the adhesion.
- the lift table can too from both upwards and downwards Lift cylinders are driven, which varies depending on the type of pressure forces to be applied. Since the pressure rooms of the lifting cylinders must not be impaired it conveniently on the side outside of the lifting table and the concerned press table.
- the press according to the invention is in the form of a modular system expandable. So can be above the upper press table or a third pressure chamber below the lower press table located from an above or below, driven via lifting cylinders mounted on the frame second lifting table is limited.
- Such a press with three pressure rooms or one with two neighboring pressure rooms, always two these pressure rooms open and close alternately, can be combined with each other and on top of each other being constructed. So each can be made up of two fixed ones Press tables with two by one arranged in between A first press room separate from each other Form press unit. A second press unit is obtained by having two of these fixed press tables with in between arranged two separated by a lifting table Press rooms around one arranged above or below third pressure chamber supplemented with a second lifting table.
- the on press units formed in this way can be any can be combined with each other, with the sides of the fixed press tables adjacent press units one each have only one press table in common at their interface can.
- the press according to the invention can, as far as the individual Pressure rooms, also as a so-called multi-daylight press be carried out at the relevant pressure rooms by means of intermediate plates in two or more floors are divided. These intermediate plates can be used as required be designed as heatable plates.
- FIG. 1 shows a machine frame 1, which has vertical columns, which over suitable Connection means 12 with an upper fixed press table 2 and a lower fixed press table 3 are connected. Between two fixed press tables 2 and 3 are in Height direction adjustable lift table 4, the top a first pressure chamber 5 and a second downwards Pressure chamber 6 limited. Since the distance between the fixed press tables 2 and 3 is constant, changes when the lifting table 4 moves between the two fixed press tables 2 and 3 the height of the Pressure rooms 5 and 6 depending on each other, so that how in the embodiment of Figure 1 in the pressing process in second, lower press room 6, the upper press room 5 is open.
- the material to be arranged in the press rooms 5 and 6 is in the Drawing not shown in detail, you can see in the Print rooms 5 and 6 only intermediate plates 8, which the Subdivide pressure rooms 5 and 6 into several floors.
- the lifting table 4 is driven by double-acting Lift cylinders 7, the side outside on the lifting table 4 and on upper press table 2 are articulated.

Abstract
Description
Die Erfindung bezieht sich auf eine Presse zum Verpressen von
plattenförmigen Werkstücken mit zumindest zwei Druckräumen
der im Gattungsbegriff des Patentanspruchs 1 näher
gekennzeichneten Art.The invention relates to a press for pressing
plate-shaped workpieces with at least two pressure chambers
the closer in the preamble of
Aus der DE-U-88 06 883 ist eine solche Vorrichtung zum Heißverpressen von plattenförmigen Werkstücken bekannt, bei der sich an einen festen Preßtisch, d.h. Mittelteil, oberhalb und unterhalb jeweils eine sogenannte Etagenheißpresse mit jeweils nach unten und nach oben hin beweglichen Druckbalken anschließt und beide Etagenheißpressen unabhängig voneinander durch Kolben aufweisende Druckzylinder betätigt werden können, so daß die beiderseites des festen Preßtisches bzw. des Mittelteils angeordneten Etagenheißpressen, d.h. Druckräume, unabhängig voneinander geöffnet und geschlossen werden können. Entsprechend kann jeder Druckraum bzw. jede Etagenheißpresse für sich beschickt oder aus ihr das Preßgut entnommen werden, weswegen man grundsätzlich für die beiden dem festen Preßtisch, d.h. dem Mittelteil benachbarten Etagenheißpressen unterschiedliche Arbeitszyklen vorsehen kann.From DE-U-88 06 883 such a device for Hot pressing of plate-shaped workpieces known, at which is attached to a fixed press table, i.e. Middle part, above and below each with a so-called hot plate press pressure beams movable downwards and upwards connects and both floor hot presses independently of each other are actuated by pressure cylinders having pistons can, so that the two sides of the fixed press table or of the central part of the stack hot presses, i.e. Pressure rooms, opened and closed independently of each other can be. Accordingly, each pressure room or each Floor hot press loaded for itself or the material to be pressed from it are taken out, which is why you basically for the two the fixed press table, i.e. the middle part adjacent Provide floor hot presses for different work cycles can.
Erforderlich ist es dabei allerdings, daß jedem Druckraum ein gesonderter Hubtisch, d.h. gesonderte Druckbalken nebst zugehöriger Hubzylinder, d.h. Druckmittelzylinder mit Kolben, zugeordnet werden.However, it is necessary for each pressure chamber to have one separate lifting table, i.e. separate pressure bar and associated lifting cylinder, i.e. Pressure cylinder with piston, be assigned.
Bei einer aus der EP 0 384 958 B1 bekannten Presse schließt sich an einen festen Preßtisch jeweils nach unten und nach oben hin ein beweglicher Hubtisch an, und beide Hubtische können unabhängig voneinander durch Hubzylinder betätigt werden, so daß die beidseits des festen Preßtisches benachbarten Druckräume unabhängig voneinander geöffnet und geschlossen werden können. Entsprechend kann jeder Druckraum, der auch Druckkammer genannt wird, für sich beschickt oder aus ihm das Preßgut entnommen werden, weswegen man grundsätzlich für die beide dem festen Preßtisch benachbarten Druckräume unterschiedliche Arbeitszyklen vorsehen kann.Closes in a press known from EP 0 384 958 B1 down and down on a fixed press table a movable lifting table at the top, and both lifting tables can be operated independently of each other by lifting cylinders be so that the both sides of the fixed press table neighboring pressure rooms opened independently of each other and can be closed. Accordingly, every pressure room, which is also called the pressure chamber, loaded by itself or the pressed material can be removed from it, which is why basically for the two adjacent to the fixed press table Print rooms can provide different working cycles.
In der Praxis muß das in der Regel in Sandwich-Weise geschichtete Preßgut, das meist unter Einsatz von Wärme heiß zu verpressen ist, über eine vorbestimmte Zeitspanne unter Preßdruck gehalten werden kann, und man nutzt diese Verweilzeit in der Presse, um in dem jeweils benachbarten, geöffneten Druckraum das Preßgut auszutauschen. Durch entsprechende Peripherie-Geräte der Presse kann die Dauer für den Preßgutwechsel bei dem geöffneten Druckraum gleich lang oder sogar kürzer als die Zeitspanne eingerichtet werden, die zum, Verpressen des Preßgutes im geschlossenen Druckraum notwendig ist.In practice, this usually has to be done in a sandwich manner layered pressed material, which is usually hot using heat is to be pressed over a predetermined period of time Press pressure can be kept, and one uses this Time in the press to be in the neighboring, open pressure chamber to replace the material to be pressed. By corresponding peripheral devices of the press can last for the material to be pressed with the open pressure chamber the same length or even shorter than the amount of time that for pressing the material to be pressed in the closed pressure chamber necessary is.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Presse der gattungsbildenden Art zu schaffen, bei der zwei einander benachbarte Druckräume miteinander abwechselnd geöffnet und geschlossen werden können.The invention is therefore based on the object of a press of the generic type in which two create each other neighboring pressure rooms alternately opened and can be closed.
Diese Aufgabe wird bei einer gattungsgemäßen Presse durch die
kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This task is performed in a generic press by
characterizing features of
Für die erfindungsgemäße Presse ist wesentlich, jeweils zwischen zwei festen Preßtischen nur einen beweglichen Hubtisch zu benötigen, was den baulichen Aufwand vereinfacht, denn ein Hubtisch mit dem Hubwerk ist konstruktiv aufwendiger als ein gestellfest anzuordnender Preßtisch. So kommt dem Hubtisch bezogen auf die beiden Preßräume eine Doppelfunktion zu, denn im ersten Arbeitszyklus verpreßt er das Preßgut des einen Druckraums gegen den ersten festen Preßtisch, wobei der davon abgelegene Druckraum offen ist, und im zweiten Arbeitszyklus wird das Preßgut im zweiten Druckraum gegen den zweiten festen Preßtisch verpreßt, während der erste Druckraum geöffnet ist.It is essential for the press according to the invention, in each case only one movable between two fixed press tables To need a lifting table, which simplifies the construction effort, because a lifting table with the lifting mechanism is structurally more complex as a press table to be fixed to the frame. This is how it comes Lifting table has a double function in relation to the two press rooms to, because in the first cycle he presses the material to be pressed a pressure chamber against the first fixed press table, the remote pressure room is open, and in the second Working cycle is the material to be pressed in the second pressure chamber against the second fixed press table pressed while the first Print room is open.
Vorteilhaft werden für den Antrieb des Hubtisches doppelt wirkende Hubzylinder eingesetzt, die sich beim Hubtisch aus entweder nach oben oder nach unten hin zum entsprechenden Gegenlager am Maschinengestell erstrecken. Zweckmäßig sind die Hubzylinder unmittelbar am oberhalb oder unterhalb des Hubtisches benachbarten festen Preßtisch gegengelagert, was den Weg des Kraftschlusses verkürzt. Der Hubtisch kann auch von sowohl nach oben als auch nach unten hin angeordneten Hubzylindern angetrieben werden, was sich je nach Art der aufzubringenden Druckkräfte richtet. Da die Druckräume von den Hubzylindern nicht beeinträchtigt werden dürfen, sitzen sie zweckmäßig seitlich außen am Hubtisch und dem betreffenden Preßtisch.Double are advantageous for the drive of the lifting table acting lifting cylinders used, which are at the lifting table either up or down to the corresponding one Extend the counter bearing on the machine frame. Are expedient the lifting cylinder immediately above or below the Lift table adjacent fixed press table, what shortens the path of the adhesion. The lift table can too from both upwards and downwards Lift cylinders are driven, which varies depending on the type of pressure forces to be applied. Since the pressure rooms of the lifting cylinders must not be impaired it conveniently on the side outside of the lifting table and the concerned press table.
Die erfindungsgemäße Presse ist nach Art eines Baukastens ausbaufähig. So kann sich oberhalb des oberen Preßtisches oder unterhalb des unteren Preßtisches ein dritter Druckraum befinden, der von einem darüber bzw. darunter angeordneten, über gestellfest gegengelagerte Hubzylinder angetrieben zweiten Hubtisch begrenzt ist.The press according to the invention is in the form of a modular system expandable. So can be above the upper press table or a third pressure chamber below the lower press table located from an above or below, driven via lifting cylinders mounted on the frame second lifting table is limited.
Eine solche Presse mit drei Druckräumen oder auch diejenige mit zwei benachbarten Druckräumen, wobei sich immer zwei dieser Druckräume alternierend öffnen und schließen lassen, können beliebig miteinander kombiniert und übereinander aufgebaut werden. So läßt sich jeweils aus zwei festen Preßtischen mit dazwischen angeordneten zwei durch einen Hubtisch voneinander getrennten Preßräumen eine erste Presseneinheit bilden. Eine zweite Presseneinheit erhält man dadurch, daß man zwei dieser festen Preßtische mit dazwischen angeordneten zwei durch einen Hubtisch voneinander getrennten Preßräumen um einen darüber oder darunter angeordneten dritten Druckraum mit einem zweiten Hubtisch ergänzt. Die auf diese Weise gebildeten Presseneinheiten können beliebig miteinander kombiniert werden, wobei mit den Seiten der festen Preßtische benachbarte Presseneinheiten jeweils einen einzigen Preßtisch an ihrer Nahtstelle gemeinsam haben können.Such a press with three pressure rooms or one with two neighboring pressure rooms, always two these pressure rooms open and close alternately, can be combined with each other and on top of each other being constructed. So each can be made up of two fixed ones Press tables with two by one arranged in between A first press room separate from each other Form press unit. A second press unit is obtained by having two of these fixed press tables with in between arranged two separated by a lifting table Press rooms around one arranged above or below third pressure chamber supplemented with a second lifting table. The on press units formed in this way can be any can be combined with each other, with the sides of the fixed press tables adjacent press units one each have only one press table in common at their interface can.
Die erfindungsgemäße Presse kann, soweit es die einzelnen Druckräume betrifft, auch als sogenannte Mehretagenpresse ausgeführt werden, bei der die betreffenden Druckräume mittels Zwischenplatten in zwei oder mehreren Etagen unterteilt sind. Je nach Bedarf können diese Zwischenplatten als heizbare Platten ausgebildet sein.The press according to the invention can, as far as the individual Pressure rooms, also as a so-called multi-daylight press be carried out at the relevant pressure rooms by means of intermediate plates in two or more floors are divided. These intermediate plates can be used as required be designed as heatable plates.

beiden festen Preßtischen 2 und 3 befindet sich ein in
Höhenrichtung verstellbarer Hubtisch 4, der nach oben hin
einen ersten Druckraum 5 und nach unten hin einen zweiten
Druckraum 6 begrenzt. Da der Abstand der festen Preßtische 2
und 3 konstant ist, ändert sich bei Bewegung des Hubtisches 4
zwischen den beiden festen Preßtischen 2 und 3 die Höhe der
Druckräume 5 und 6 in Abhängigkeit voneinander, so daß wie
beim Ausführungsbeispiel nach Fig.1 beim Preßvorgang im
zweiten, unteren Preßraum 6 der obere Preßraum 5 offen ist.
Das in den Preßräumen 5 und 6 anzuordnende Preßgut ist in der
