Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung von Betonformteilen.The invention relates to a device for producing concrete moldings.
Vorrichtungen zur Herstellung von Betonformteilen, wie z. B. Pflastersteinen werden typischerweise zur maschinellen Fertigung eingesetzt und enthalten eine Formmaschine mit einer Stempeleinheit und ein als Form ausgebildetes Formunterteil, in das die Stempeleinheit eingreifen kann. In dem Formunterteil sind üblicherweise ein oder mehrere Formnester ausgebildet, die nach oben und unten geöffnet sind. Das Formunterteil wird mit einer unteren Begrenzungsebene eines Steinfelds auf eine horizontale Unterlage aufgesetzt, die die unteren Öffnungen der Form verschließt. Durch die oberen Öffnungen werden die Formnester mit Betongemenge befüllt, das anschließend über an der Stempeleinheit angeordnete Druckplatten gepresst wird, in dem die Druckplatten durch die oberen Öffnungen in die Formnester eingesenkt werden. Anschließen erfolgt durch Rütteln typischerweise der Unterlage eine Verfestigung des Betongemenges zu formstabilen Betonformteilen. Diese werden durch die unteren Öffnungen der Formnester entformt.Devices for the production of concrete moldings, such. As paving stones are typically used for machining and contain a molding machine with a punch unit and a form of a molded mold base, in which the punch unit can intervene. In the lower mold part usually one or more mold cavities are formed, which are open up and down. The mold base is placed with a lower boundary plane of a stone field on a horizontal surface, which closes the lower openings of the mold. Through the upper openings, the mold nests are filled with concrete amount, which is then pressed through arranged on the stamp unit printing plates in which the printing plates are sunk through the upper openings in the mold cavities. Connecting is done by shaking typically the pad a solidification of the concrete amount to form-stable concrete moldings. These are removed from the mold through the lower openings of the mold cavities.
Die Stempeleinheit ist mit einer typischerweise hydraulisch betätigten Vertikalbewegungseinheit der Formmaschine verbunden und mittels dieser vertikal verfahrbar. Die Verbindung kann in gebräuchlicher Bauweise über eine Auflasteinheit gegeben sein, die gewöhnlich mit der Stempeleinheit ein Formoberteil als einheitlich handhabbare Baugruppe bildet. Mittels eines Anschlags an Stempeln der Stempeleinheit wird eine gleichmäßige Steinhöhe auch bei unterschiedlicher Verdichtung des Betongemenges erreicht.The stamp unit is connected to a typically hydraulically actuated vertical movement unit of the molding machine and by means of this vertically movable. The connection can be given in conventional construction via a Auflasteinheit, which usually forms with the stamp unit a Formoberteil as uniformly manageable assembly. By means of a stop on stamping the stamp unit a uniform stone height is achieved even with different compression of the concrete amount.
Bei der Konstruktion einer derartigen Vorrichtung zur Herstellung von Betonformteilen kommt insbesondere der Befestigung der Stempeleinheit an dem Formoberteil und an den Druckplatten besondere Bedeutung zu, da diese die Positionierung der Stempel und eine stabile Abstützung der Stempel gegen verkippend und/oder tordierend wirkende Kräfte ermöglichen muss.In the construction of such a device for the production of concrete moldings is in particular the attachment of the stamp unit to the Form top and on the printing plates of particular importance, since they must allow the positioning of the stamp and a stable support of the stamp against tilting and / or tordierend acting forces.
Aus dem allgemeinen Stand der Technik sind Vorrichtungen bekannt, bei denen ein Stempel mittels einer Schweißverbindung mit einer Anschraubplatte verbunden ist, an die eine Druckplatte zum leichteren Auswechseln angeschraubt ist.Devices are known from the general state of the art, in which a punch is connected by means of a welded connection to a screw-on plate, to which a pressure plate is screwed for easier replacement.
So wird zum Beispiel in der
Es ist daher Aufgabe der Erfindung, eine Vorrichtung zur Herstellung von Betonformteilen zu schaffen, die auf einfache und vorteilhafte Weise herstellbare Druckstempel aufweist, die darüber hinaus auch ohne materialbearbeitende Eingriffe austauschbar sind.It is therefore an object of the invention to provide an apparatus for producing concrete moldings, which has in a simple and advantageous manner manufacturable plunger, which are also interchangeable without material-processing operations.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind jeweils Gegenstand der Unteransprüche. Diese können in technologisch sinnvoller Weise miteinander kombiniert werden. Die Beschreibung, insbesondere im Zusammenhang mit der Zeichnung, charakterisiert und spezifiziert die Erfindung zusätzlich.This object is solved by the features of
Gemäß der Erfindung wird eine Vorrichtung zur Herstellung von Betonformteilen in einer Formmaschine geschaffen, die ein Formoberteil mit einer Druckplattenanordnung mit mehreren jeweils einer Öffnung eines Formnests zugewandten Druckplatten umfasst, wobei jede der Druckplatten mit einer Zwischenplatte verschraubt ist, wobei die Zwischenplatte auf der dem Formoberteil zugewandten Seite über wenigstens einen Druckstempel mit einer Stempelplatte am Formoberteil verbunden ist, dadurch gekennzeichnet, dass die Zwischenplatte mit der Stempelplatte verspannt ist, in dem durch eine Aufnahme auf der Zwischenplatte wenigstens ein Bolzen geführt ist, der in die Stempelplatte lösbar eingreift, wobei der Druckstempel einen Hohlkörper umfasst, der zwischen der Zwischenplatte und der Stempelplatte den Bolzen umschließt.According to the invention there is provided an apparatus for producing concrete moldings in a molding machine comprising a mold top having a pressure plate assembly having a plurality of pressure plates each facing an opening of a mold cavity, each of the pressure plates being bolted to an intermediate plate, the intermediate plate facing on the mold top Side is connected via at least one plunger with a stamp plate on the upper mold, characterized in that the intermediate plate is clamped to the stamp plate in which by a recording on the intermediate plate at least one bolt is guided, which releasably engages the stamp plate, wherein the plunger a Hollow body includes, which surrounds the bolt between the intermediate plate and the punch plate.
Somit besteht ein Grundgedanke der Erfindung darin, den Druckstempel als Hohlkörper auszuführen, in dessem inneren ein Bolzen geführt ist. Der Bolzen ist einerseits lösbar mit der Zwischenplatte, beispielsweise über eine Verschraubung verbunden. Andererseits wird der Bolzen durch eine Aufnahme in der Zwischenplatte geführt, so dass zwischen der Zwischenplatte und der Stempelplatte eine eine Verspannung erzeugende mechanische Verbindung besteht, wobei der Hohlkörper zur Kraftübertragung zwischen der Stempelplatte und der Zwischenplatte vorgesehen ist. Demnach wird die bisher im Stand der Technik vorherrschende Verschweißung von Druckstempeln vermieden, so dass eine lösbare Befestigung zwischen den einzelnen Komponenten einer Formmaschine geschaffen wird. Dies ermöglicht eine kostengünstige Fertigung von Formmaschinen und erlaubt darüber hinaus Verschleißteile oder in Folge einer Umrüstung auf andere Steinformen erforderliche Nachrüstungen auf einfache Weise durch Austausch der entsprechenden Komponenten vorzunehmen.Thus, a basic idea of the invention is to make the plunger as a hollow body, in whose inner a bolt is guided. The bolt is on the one hand releasably connected to the intermediate plate, for example via a screw. On the other hand, the bolt is guided by a receptacle in the intermediate plate, so that between the intermediate plate and the punch plate is a stress-generating mechanical connection, wherein the hollow body is provided for transmitting power between the punch plate and the intermediate plate. Accordingly, the previously prevailing in the art welding of stamps is avoided, so that a releasable attachment between the individual components of a molding machine is created. This allows a cost-effective production of molding machines and also allows wearing parts or retrofit required by retrofitting to other stone shapes retrofitting in a simple manner by replacing the corresponding components.
Gemäß einer Ausführungsform der Erfindung ist die Aufnahme als Einsenkung gebildet, die entlang einer Richtung senkrecht zur Oberfläche der Zwischenplatte einen stufenförmigen Querschnitt aufweist.According to one embodiment of the invention, the receptacle is formed as a depression which has a step-shaped cross-section along a direction perpendicular to the surface of the intermediate plate.
Der stufenförmige Querschnitt kann insbesondere dazu vorgesehen sein, eine Befestigungsmöglichkeit für den Bolzen zu schaffen, so dass sich der Bolzen in axialer Richtung von der Seite der Druckplatte her gegen die Zwischenplatte abstützen kann. Dies ermöglicht es, auf der gegenüber liegenden Seite im Bereich der Stempelplatte ein entsprechendes Gegenelement vorzusehen, so dass die Verspannung zwischen der Zwischenplatte und der Stempelplatte erreicht wird, wobei der Abstand zwischen den beiden Platten durch den Hohlkörper festgelegt ist.The step-shaped cross-section may in particular be provided to provide a possibility for fastening the bolt, so that the bolt can be supported against the intermediate plate in the axial direction from the side of the pressure plate. This makes it possible to provide a corresponding counter element on the opposite side in the region of the stamp plate, so that the clamping between the intermediate plate and the stamp plate is achieved, wherein the distance between the two plates is fixed by the hollow body.
Gemäß einer weiteren Ausführungsform der Erfindung weist der stufenförmige Querschnitt auf der der Stempelplatte zugewandten Seite der Zwischenplatte eine erste Innenabmessung auf, die einer Außenabmessung des Bolzens entspricht.According to a further embodiment of the invention, the step-shaped cross-section on the stamp plate facing side of the intermediate plate on a first inner dimension, which corresponds to an outer dimension of the bolt.
Um den Bolzen durch die Zwischenplatte führen zu können, ist es demnach vorgesehen, den stufenförmigen Querschnitt der Aufnahme so zu wählen, dass der Bolzen durch die Zwischenplatte durchführbar ist.In order to be able to guide the bolt through the intermediate plate, it is therefore provided to choose the step-shaped cross section of the receptacle so that the bolt can be performed by the intermediate plate.
Gemäß einer weiteren Ausführungsform der Erfindung weist der stufenförmige Querschnitt auf der der Druckplatte zugewandten Seite der Zwischenplatte eine zweite Innenabmessung auf, die größer als die erste Innenabmessung gewählt ist.According to a further embodiment of the invention, the step-shaped cross-section on the pressure plate facing side of the intermediate plate on a second inner dimension, which is selected to be larger than the first inner dimension.
Der stufenförmige Querschnitt setzt sich nun in Richtung der Druckplatte so fort, dass eine Aufweitung des Querschnitts erfolgt, die durch eine zweite Innenabmessung charakterisiert wird.The stepped cross-section is now continued in the direction of the pressure plate so that an expansion of the cross-section is carried out, which is characterized by a second inner dimension.
Gemäß einer weiteren Ausführungsform der Erfindung ist im Bereich der zweiten Innenabmessung in der Zwischenplatte ein am Bolzen angebrachter Schraubenkopf einbringbar, der auf der der Druckplatte zugewandten Seite unterhalb der Oberfläche der Zwischenplatte angeordnet ist.According to a further embodiment of the invention, a bolt head mounted on the bolt can be introduced in the region of the second inner dimension in the intermediate plate, which is arranged on the pressure plate facing side below the surface of the intermediate plate.
Der stufenförmige Querschnitt ist somit geeignet, einen am Ende des Bolzens angebrachten Schraubenkopf, der beispielsweise als Sechskant, Schlitzschraubenkopf oder dergleichen ausgeführt sein kann, so unterzubringen, dass die darüber liegende Druckplatt diesen vollständig überdeckt und auf der Oberfläche der Zwischenplatte aufliegt. Die Verwendung eines Schraubenkopfes am Ende des Bolzens stellt eine einfache Möglichkeit dar, die gewünschte Verspannung zwischen der Zwischenplatte und der Stempelplatte zu erzeugen.The step-shaped cross-section is thus suitable for accommodating a screw head attached to the end of the bolt, which may be designed, for example, as a hexagon, slotted head or the like, such that the overlying pressure plate completely covers it and rests on the surface of the intermediate plate. The use of a screw head at the end of the bolt provides an easy way to create the desired tension between the intermediate plate and the stamp plate.
Gemäß einer weiteren Ausführungsform der Erfindung ist im Bereich der zweiten Innenabmessung in der Zwischenplatte eine in ein Außengewinde des Bolzens eingreifende Mutter einbringbar, die auf der der Druckplatte zugewandten Seite unterhalb der Oberfläche der Zwischenplatte angeordnet ist.According to a further embodiment of the invention in the region of the second inner dimension in the intermediate plate, an engaging in an external thread of the bolt nut can be introduced, which is arranged on the pressure plate facing side below the surface of the intermediate plate.
Im Gegensatz zum vorherigen Ausführungsbeispiel wird hier der Bolzen nicht mit einem Schraubenkopf versehen sondern kann beispielsweise als Gewindestange bereit gestellt werden, in die im Bereich der zweiten Innenabmessung eine Mutter in Eingriff gebracht wird. Auch gemäß dieser Vorgehensweise ist eine Verspannung zwischen Stempelplatte und Zwischenplatte möglich.In contrast to the previous embodiment, the bolt is not provided here with a screw head but can be provided for example as a threaded rod, in which in the region of the second inner dimension, a nut is brought into engagement. Also according to this procedure, a tension between the punch plate and intermediate plate is possible.
Gemäß einer weiteren Ausführungsform der Erfindung ist der Hohlkörper als Hohlzylinder ausgebildet, dessen Oberkante und dessen Unterkante in axialer Richtung planparallel zueinander ausgerichtet sind.According to a further embodiment of the invention, the hollow body is designed as a hollow cylinder, the upper edge and the lower edge are aligned plane-parallel to each other in the axial direction.
Um eine möglichst gleichförmige und spannungsfreie Kraftübertragung der Auflasteinheit zu den Druckplatten zu ermöglichen, ist es vorteilhaft, dass die Seitenflächen des Hohlzylinders planparallel zueinander ausgerichtet sind, wobei es im Rahmen der Erfindung auch vorgesehen sein kann, die Seitenflächen an der Oberkante bzw. der Unterkante lediglich abschnittsweise parallel zueinander auszurichten, so dass beispielsweise einzelne Vorsprünge gebildet werden, deren Lücken nicht notwendigerweise parallel ausgebildet sein müssen.In order to enable the most uniform and stress-free power transmission of Auflasteinheit to the printing plates, it is advantageous that the side surfaces of the hollow cylinder are aligned plane-parallel to each other, and it may also be provided in the invention, the side surfaces on the upper edge or the lower edge only Align sections in parallel to each other, so that, for example, individual projections are formed, the gaps do not necessarily have to be formed in parallel.
Gemäß einer weiteren Ausführungsform der Erfindung ist der Bolzen mit einem kreisrunden Querschnitt ausgebildet.According to a further embodiment of the invention, the bolt is formed with a circular cross-section.
Ein möglichst einfacher Aufbau der Vorrichtung wird erreicht, in dem der Bolzen mit einem kreisrunden Querschnitt bereit gestellt wird. Im Rahmen der Erfindung ist es aber auch möglich, den Bolzen zumindest abschnittsweise mit einzelnen vom kreisrunden Querschnitt abweichenden Segmenten auszustatten, die beispielsweise als Führung in dem Hohlkörper verwendet werden können.The simplest possible structure of the device is achieved, in which the bolt is provided with a circular cross-section. In the context of the invention, it is also possible to equip the bolt at least in sections with individual deviating from the circular cross-section segments, which can be used for example as a guide in the hollow body.
Gemäß einer weiteren Ausführungsform der Erfindung ist der Bolzen im Bereich seines der Stempelplatte zugewandten Endes mit einem Außengewinde versehen.According to a further embodiment of the invention, the bolt is provided in the region of its end facing the stamp plate with an external thread.
Diese Vorgehensweise ist insbesondere dann vorteilhaft, wenn auf der Zwischenplatte der Bolzen mit einem Schraubenkopf ausgeführt ist. Demnach kann auf Seiten der Stempelplatte an dem Außengewinde eine Mutter befestigt werden, so dass die Zwischenplatte sich über den Hohlkörper abstützend an der Stempelplatte mittels einer Verschraubung befestigt wird. Wie bereits erwähnt, ist es aber auch möglich, auf der Seite der Zwischenplatte eine Mutter vorzusehen und den Schraubenkopf beispielsweise von Seiten der Stempelplatte einzuführen, sofern die Auflasteinheit in diesem Bereich genügend Platz für eine Durchführung einer Schraube ermöglichen sollte.This procedure is particularly advantageous if the bolt is designed with a screw head on the intermediate plate. Accordingly, a nut can be attached to the outer thread on the side of the stamp plate be, so that the intermediate plate is attached to the hollow body supporting the stamp plate by means of a screw. However, as already mentioned, it is also possible to provide a nut on the side of the intermediate plate and to introduce the screw head, for example, from the side of the stamp plate, provided that the loading unit in this region should allow sufficient space for a screw to pass through.
Gemäß einer weiteren Ausführungsform der Erfindung sind für jede Zwischenplatte eine Vielzahl von Bolzen und Hohlkörpern vorgesehen.According to a further embodiment of the invention, a plurality of bolts and hollow bodies are provided for each intermediate plate.
Diese Vorgehensweise ermöglicht eine stabile Befestigung der Zwischenplatte an der Stempelplatte, wobei die Anzahl der Bolzen und Hohlkörper je nach zu erwartender mechanischer Beanspruchung entsprechend gewählt wird. So kann es beispielsweise vorgesehen sein, die Zwischenplatte mit einer im Wesentlichen rechteckigen Grundfläche auszuführen, wobei an den beiden längeren Seiten jeweils zwei oder mehr Bolzen und Hohlkörper angeordnet sind.This procedure allows a stable attachment of the intermediate plate to the stamp plate, wherein the number of bolts and hollow body is selected according to the expected mechanical stress accordingly. Thus, it may be provided, for example, to carry out the intermediate plate with a substantially rectangular base, wherein two or more bolts and hollow bodies are arranged on the two longer sides.
Gemäß einer weiteren Ausführungsform der Erfindung umfasst die Zwischenplatte Öffnungen, über die ein Befestigungselement durchführbar ist, um eine Verschraubung mit der Druckplatte durchzuführen.According to a further embodiment of the invention, the intermediate plate comprises openings, via which a fastening element can be carried out in order to carry out a screw connection to the pressure plate.
Um die Druckplatte mit der Zwischenplatte zu befestigen, wird gemäß dieser Vorgehensweise ein Befestigungselement durch entsprechende Öffnungen durchgeführt, um eine Verschraubung vornehmen zu können. Dabei kann das Befestigungselement beispielsweise als Gewindestange mit dazu gehöriger Mutter ausgeführt sein.In order to secure the pressure plate with the intermediate plate, a fastener is performed by appropriate openings according to this procedure in order to make a screw. In this case, the fastening element may for example be designed as a threaded rod with associated mother.
Gemäß einer weiteren Ausführungsform der Erfindung ist die Zwischenplatte einstückig gebildet.According to a further embodiment of the invention, the intermediate plate is integrally formed.
Die Zwischenplatte wird vorteilhafterweise zusammen mit den Öffnungen bzw. den Aufnahmen für die Bolzen aus einem Stück gefertigt, so dass zum einen Fertigungskosten reduziert werden können, aber zum anderen auch ein stabiler Aufbau erreicht wird.The intermediate plate is advantageously made together with the openings or the receptacles for the bolts in one piece, so that on the one hand manufacturing costs can be reduced, but on the other hand, a stable construction is achieved.
Gemäß einer weiteren Ausführungsform der Erfindung bildet der Außenumfang der Zwischenplatte zusammen mit Innenflächen der Aufnahmen und den Öffnungen eine geschlossene Kurve.According to a further embodiment of the invention, the outer periphery of the intermediate plate together with inner surfaces of the receptacles and the openings forms a closed curve.
Demnach ist es vorgesehen, dass die Aufnahmen bzw. die Öffnungen in der Zwischenplatte nicht als isolierte Löcher ausgebildet werden, sondern entlang des Außenumfangs entlang einer einzigen geschlossenen Kurve abgefahren werden können. Dies ermöglicht es, die Zwischenplatte gemäß der Erfindung in einem einzigen Bearbeitungsschritt beispielsweise durch ein Laserschneidverfahren, aus einem plattenförmigen Grundkörper herzustellen. Nach Beendigung des Ausbildens der Außenkontur der Zwischenplatte muss anschließend lediglich eine Nachbearbeitung zur Ausbildung des stufenförmigen Querschnitts vorgenommen werden, wobei dieser Bearbeitungsschritt jedoch keine großen Anforderungen an die einzuhaltenden Fertigungstoleranzen stellt, da der Abstand zwischen der Zwischenplatte und der Stempelplatte durch die Hohlkörper gegeben ist und im Bereich der zweiten Innenabmessungen lediglich Platz für einen Schraubenkopf bzw. eine Mutter geschaffen werden muss.Accordingly, it is provided that the receptacles or the openings in the intermediate plate are not formed as isolated holes, but can be traveled along the outer circumference along a single closed curve. This makes it possible to produce the intermediate plate according to the invention in a single processing step, for example by a laser cutting process, from a plate-shaped base body. After completion of the formation of the outer contour of the intermediate plate then only a post-processing for the formation of the stepped cross-section must be made, but this processing step makes no great demands on the tolerances to be observed, since the distance between the intermediate plate and the stamp plate is given by the hollow body and in the Area of the second internal dimensions only space for a screw head or a nut must be created.
Gemäß einer weiteren Ausführungsform der Erfindung sind die Aufnahmen und die Öffnungen in der Zwischenplatte vom Außenrand der Zwischenplatte nach innen versetzt, wobei die Aufnahmen und die Öffnungen in Richtung des Außenrands weisende Aussparungen aufweisen.According to a further embodiment of the invention, the receptacles and the openings in the intermediate plate are offset inwardly from the outer edge of the intermediate plate, wherein the receptacles and the openings in the direction of the outer edge facing recesses.
Die in Form von Bohrlöchern vorgesehenen Aufnahmen bzw. Öffnungen können zum einen direkt am Außenrand der Zwischenplatte gebildet sein, wobei es mit dem soeben beschriebenen Laserschneidverfahren auch vorgesehen ist, die entsprechenden Löcher für die Aufnahmen und Öffnungen weiter vom Außenrand der Zwischenplatte entfernt auszubilden, in dem vom Außenrand zu den Öffnungen bzw. Aufnahmen entsprechende Aussparungen gebildet werden. Dies ermöglicht es, die Querschnittsfläche der Hohlkörper zu vergrößern, so dass der über die Hohlkörper und Bolzen gebildete Druckstempel eine hohe Stabilität aufweist.The receptacles or openings provided in the form of boreholes may be formed directly on the outer edge of the intermediate plate, wherein it is also provided with the laser cutting method just described to form the corresponding holes for the receptacles and openings further away from the outer edge of the intermediate plate, in which from the outer edge to the openings or recordings corresponding recesses are formed. This makes it possible to increase the cross-sectional area of the hollow body, so that the pressure stamp formed over the hollow body and bolt has a high stability.

In axialer Richtung ist der Hohlkörper HO zwischen seiner Oberkante OK und seiner Unterkante UK mit einer Länge ausgeführt, die kürzer als die des Bolzens BO gewählt ist. Demnach ist es möglich, dass der Bolzen sowohl über die Oberkante OK als auch die Unterkante UK hinaus ragt, so dass ein dort angebrachtes Außengewinde AG zur Verschraubung mit der Stempelplatte ST bzw. der Zwischenplatte ZW genutzt werden kann.In the axial direction of the hollow body HO between its upper edge OK and its lower edge UK is designed with a length which is shorter than that of the bolt BO. Accordingly, it is possible for the bolt to protrude beyond both the upper edge OK and the lower edge UK, so that an external thread AG mounted there can be used for screwing to the stamp plate ST or the intermediate plate ZW.
Demnach werden die Druckstempel DS in der Ausführungsform der
Um die Übertragung der Druckkräfte beim Absenken des Formoberteils FB möglichst gleichmäßig auf die Druckplatten DP übertragen zu können, ist es insbesondere vorgesehen, dass die Seitenflächen der Hohlkörper HO im Bereich der Oberkante OK und der Unterkante UK planparallel zueinander ausgeführt sind, so dass eine über die Auflasteinheit AE von oben eingeführte senkrecht wirkende Kraft spannungsfrei an die Druckplatten DP übertragen wird.In order to transfer the transfer of compressive forces when lowering the upper mold FB as evenly as possible on the printing plates DP, it is provided in particular that the side surfaces of the hollow body HO in the region of the upper edge OK and the lower edge UK are performed plane-parallel to each other, so that one on the Auflasteinheit AE introduced from above vertically acting force is transmitted stress-free to the printing plates DP.

Dazu kann insbesondere ein entsprechend vorbearbeiteter Metallkörper verwendet werden, der über entsprechende planparallele Hauptflächen verfügt und mittels eines Laserschneidverfahrens in einem einzigen Arbeitsschritt mit den entsprechenden Aufnahmen AN bzw. den Öffnungen OE versehen wird. In einem Nachbearbeitungsschritt wird anschließend der stufenförmige Querschnitt der Aufnahme AN in der Zwischenplatte ZW gebildet, so dass auf der der Druckplatte DP zugewandten Seite der Zwischenplatte ZW eine zweite Innenabmessung IA2 entsteht, die größer als die erste Innenabmessung IA1 gewählt ist. Somit kann im Bereich dieser stufenförmigen Einsenkung ein Schraubenkopf oder eine Mutter eingebracht werden, mit der der Bolzen BO an seinem Außengewinde AG verschraubt wird, um die Zwischenplatte ZW gegen die Hohlkörper HO zu verspannen.For this purpose, in particular a correspondingly pre-machined metal body can be used, which has corresponding plane-parallel main surfaces and is provided by means of a laser cutting process in a single step with the corresponding recordings AN or the openings OE. In a post-processing step, the step-shaped cross section of the receptacle AN in the intermediate plate ZW is subsequently formed so that a second inner dimension IA2, which is greater than the first inner dimension IA1, is formed on the side of the intermediate plate ZW facing the pressure plate DP. Thus, a screw head or a nut can be introduced in the region of this stepped depression, with which the bolt BO is screwed to its external thread AG in order to clamp the intermediate plate ZW against the hollow body HO.
