The dampers have a profiled, esp. triangular cross-section with one or more protuberances (10) or recesses (11) fitting into matching recesses or protuberances on the insert and/or frame.

Description

Die Erfindung betrifft eine Rüttelform, bestehend aus einem Einsatz mit einem oder mehreren Formnestern zur Aufnahme von rieselfähigen Massen, insbesondere Beton zur Herstellung von Formsteinen, wobei der Einsatz auf einem Rütteltisch der Formmaschine angeordnet und mit einem vertikal beweglichen Formrahmen der Formmaschine verbunden ist.The invention relates to a vibrating mold, consisting of an insert with one or more mold nests for receiving pourable masses, in particular concrete, for the production of molded blocks, the insert being arranged on a vibrating table of the molding machine and connected to a vertically movable molding frame of the molding machine.

Bei den bekannten Rüttelformen dieser Art, die zur Herstellung von Betonsteinen dienen, ist der Formrahmen mit dem Formeinsatz, der die Formnester enthält, fest verschraubt oder verschweißt. Der Formeinsatz wird zunächst mit Hilfe des Formrahmens, der an der Formmaschine vertikal beweglich gelagert und angetrieben ist, auf dem Rütteltisch der Formmaschine abgesetzt. Dann werden die Formnester des Formeinsatzes mit Betonmasse gefüllt. Anschließend wird der Rütteltisch durch einen Exzenter- oder Unwucht-Antrieb in Schwingungen versetzt, durch die die Betonmasse in den Formnestern gleichmäßig verteilt und verdichtet wird. Nachteilig hierbei ist, daß die Rüttelbewegungen des Formeinsatzes über den Formrahmen auch auf die Maschine übertragen werden. Dadurch kann es zu Beschädigungen des Formrahmens und anderer Maschinenteile der Formmaschine kommen. Die Folge davon sind teure Reparatur- und Ersatzleistungen sowie damit verbundene Ausfallzeiten der Maschine. Durch die feste Verbindung von Maschine und Formeinsatz geht schwingungstechnisch ein Teil der Rüttelenergie in der Maschine verloren. Dies führt dazu, daß die im Formeinsatz befindliche Betonmasse nicht gleichmäßig verdichtet wird, so daß die gewünschte Qualität der fertigen Formteile nur mit größerer Rüttelenergie erreicht wird. Durch diesen Verlust muß mehr Energie von den Rüttlern aufgebracht werden. Außerdem entstehen zusätzliche Lärmquellen, weil Teile (Maschine, Rahmen) unnötig in Schwingung gebracht werden.In the known vibrating molds of this type, which are used for the production of concrete blocks, the mold frame is firmly screwed or welded to the mold insert which contains the mold cavities. The mold insert is first placed on the vibrating table of the molding machine with the help of the molding frame, which is mounted and driven vertically on the molding machine. Then the mold nests of the mold insert are filled with concrete. The vibrating table is then set in motion by an eccentric or unbalance drive, through which the concrete mass is evenly distributed and compacted in the mold nests. The disadvantage here is that the shaking movements of the mold insert can also be transferred to the machine via the mold frame. This can damage the mold frame and other machine parts of the molding machine. The consequence of this are expensive repair and replacement services and the associated downtime of the machine. Due to the fixed connection between the machine and the mold insert, some of the vibrating energy in the machine is lost in terms of vibration. This leads to the fact that the concrete mass in the mold insert is not evenly compacted, so that the desired quality of the finished molded parts can only be achieved with greater vibration energy. As a result of this loss, more energy has to be applied by the vibrators. Additional sources of noise also arise because parts (machine, frame) are caused to vibrate unnecessarily.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und das Schwingungsverhalten der Form zu verbessern.The invention has for its object to avoid the disadvantages mentioned and to improve the vibration behavior of the mold.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß zwischen Formeinsatz und Formrahmen Dämpfungsmittel vorgesehen sind.According to the invention the object is achieved in that damping means are provided between the mold insert and the mold frame.

Weitere, wesentliche Merkmale und Einzelheiten der Erfindung sind den Patentansprüchen zu entnehmen.Further essential features and details of the invention can be found in the patent claims.

Durch die erfindungsgemäße Anordnung von Dämpfungsmitteln zwischen Einsatz und Formrahmen ist der Verlust an Rüttelenergie, die im ungedämpften Zustand über den Formrahmen und die Formmaschine verloren geht, wesentlich geringer. Dadurch erhöht sich die Verdichtung der in den Formnestern befindlichen Formmassen. Die erforderliche Rüttelenergie wird geringer und damit auch die Lärmbelästigung. Außerdem wird der Verschleiß von Formrahmen und Einsatz reduziert, da in den Verbindungen zwischen Einsatz und Formrahmen keine Spannungsspitzen mehr auftreten. Das gleiche gilt auch für den Verschleiß der Formmaschine und den entsprechenden Maschinenteilen.Due to the arrangement of damping means between insert and mold frame according to the invention, the loss of vibrating energy is which is lost in the undamped state via the mold frame and the molding machine, much less. This increases the compression of the molding compounds in the mold pockets. The required vibrating energy is reduced and with it the noise pollution. In addition, the wear of the mold frame and insert is reduced, since there are no more stress peaks in the connections between the insert and the mold frame. The same also applies to the wear of the molding machine and the corresponding machine parts.

Auf einen Rütteltisch 1 einer Formmaschine 2 ist ein Einsatz 3 mit Formnestern 4 aufgesetzt. Zwischen Rütteltisch 1 und Einsatz 3 ist in bekannter Weise ein Brett 5 eingelegt. Der rechteckig ausgeführte Einsatz 3, dessen Längsseite in Fig. 1 dargestellt ist, wird von einem mit der Formmaschine 2 verbundenen Formrahmen 6 gehalten. Über seitliche Halterungen 7, die in der Formmaschine 2 vertikal beweglich und antreibbar gelagert sind, kann der Formrahmen 6 mit dem Einsatz 3 auf- und abbewegt bzw. auf den Rütteltisch 1 abgesetzt werden. Oberhalb des Rütteltisches 1 ist ein Formstempel 8 der Formmaschine 2 mit mehreren, den Formnestern 4 zugeordneten Druckplatten 9 in üblicher Weise vertikal beweglich angeordnet. Der Formrahmen 6 besteht aus zwei Längs- und zwei Querteilen, die miteinander verschraubt oder verschweißt sind.An insert 3 with mold nests 4 is placed on a vibrating table 1 of a molding machine 2. A board 5 is inserted between the vibrating table 1 and the insert 3 in a known manner. The rectangular insert 3, the long side of which is shown in FIG. 1, is held by a molding frame 6 connected to the molding machine 2. Via lateral brackets 7, which are mounted in the molding machine 2 so as to be vertically movable and drivable, the molding frame 6 can be moved up and down with the insert 3 or placed on the vibrating table 1. Above the vibrating table 1, a molding die 8 of the molding machine 2 with a plurality of pressure plates 9 assigned to the molding nests 4 is arranged to be vertically movable in the usual way. The form frame 6 consists of two longitudinal and two transverse parts which are screwed or welded together.

Wie aus Fig. 2 und 3 ersichtlich ist, weist der ebenfalls aus zwei Längs- und zwei Querteilen bestehende Einsatz 3 an seinen beiden kürzeren Querseiten einen dreieckförmigen Vorsprung 10 auf, der sich ohne Unterbrechung über die ganze Querseitenlänge des Einsatzes 3 erstreckt und in eine entsprechende Vertiefung 11 an den inneren Querseiten des Formrahmens 6 eingreift. Die Vertiefung 11 ist ebenfalls dreieckförmig mit nach innen divergierenden Seiten ausgebildet und erstreckt sich ebenfalls ohne Unterbrechung über die beiden inneren Querseiten des rechteckförmigen Formrahmens 6, der nur an seinen Querseiten über die Halterungen 7 mit der Formmaschine 2 verbunden ist.As can be seen from FIGS. 2 and 3, the insert 3, which also consists of two longitudinal and two transverse parts, has on its two shorter transverse sides a triangular projection 10 which extends without interruption over the entire transverse side length of the insert 3 and into a corresponding one Recess 11 engages on the inner transverse sides of the mold frame 6. The recess 11 is also triangular with inwardly diverging sides and also extends without interruption the two inner transverse sides of the rectangular mold frame 6, which is connected to the molding machine 2 only on its transverse sides via the holders 7.

Zwischen der Vertiefung 11 des Formrahmens 6 und dem Vorsprung 10 des Einsatzes 3 ist an der Oberseite und an der Unterseite je eine Dämpfungsplatte 12 bzw. 13 eingelegt, die sich über die ganze Länge der beiden Querseiten erstrecken. Zur Befestigung der Dämpfungsplatten 12 und 13 ist an der Unterseite des Formrahmens 6 eine Aussparung 14 für ein Druckstück 15 vorgesehen, das mit Schrauben 16 an den Formrahmen 6 angeschraubt wird (Fig. 3). Dabei werden die Dämpfungsplatten 12 und 13 über das Druckstück 15, das mit einer abgeschrägten Fläche 17 auf die untere Dämpfungsplatte 13 drückt, zwischen Formrahmen 6 und Einsatz 3 eingespannt. Die abgeschrägte Fläche 17 des Druckstücks 15 bildet zusammen mit der oberen, ebenfalls abgeschrägten Innenfläche des Formrahmens 6 die dreieckförmige Vertiefung 11, in welche die Dämpfungsplatten 12 und 13 eingelegt sind. Die Verspannung mit Hilfe der Druckstücke 15 sorgt für eine einwandfreie Halterung der Dämpfungsplatten 12, 13 und gewährleistet gleichzeitig eine feste, lösbare Verbindung zwischen Formrahmen 6 und Einsatz 3. Zur oberen Abdeckung des Formrahmens 6 und der Dämpfungsplatte 12 ist ein Verschleißblech 18 auf die Oberseite des Formrahmens 6 aufgeschraubt.Between the recess 11 of the mold frame 6 and the projection 10 of the insert 3, a damping plate 12 or 13 is inserted on the top and on the bottom, which extend over the entire length of the two transverse sides. For fastening the damping plates 12 and 13, a recess 14 for a pressure piece 15 is provided on the underside of the mold frame 6, which is screwed onto the mold frame 6 with screws 16 (FIG. 3). The damping plates 12 and 13 are clamped between the mold frame 6 and insert 3 via the pressure piece 15, which presses on the lower damping plate 13 with a bevelled surface 17. The bevelled surface 17 of the pressure piece 15 forms, together with the upper, likewise bevelled inner surface of the mold frame 6, the triangular depression 11, in which the damping plates 12 and 13 are inserted. The bracing with the help of the pressure pieces 15 ensures proper mounting of the damping plates 12, 13 and at the same time ensures a firm, detachable connection between the mold frame 6 and insert 3. For the upper cover of the mold frame 6 and the damping plate 12, a wear plate 18 is on the top of the Form frame 6 screwed on.

Für die beiden Längsseiten des Formrahmens 6 und des Einsatzes 3, die im Gegensatz zu den beiden Querseiten keine Kräfte beim Hochfahren der Form übertragen müssen, genügt es, wenn lediglich auf der Oberseite des Vorsprungs 10 und der Vertiefung 11 eine Dämpfungsplatte 12 eingelegt ist (Fig. 4). Damit werden die Kräfte zum Aufspannen des Einsatzes 6 auf den Rütteltisch 1 über die Dämpfungsplatten 12 auf den Einsatz 6 und die Halterung 7 übertragen. In diesem Fall ist es auch nicht erforderlich, den Vorsprung 10 und die Vertiefung 11 wie an den Querseiten dreieckförmig auszubilden. Es genügt, wenn die Oberseite des Vorsprungs 10 und der Vertiefung 11 eine schräge Fläche 19 aufweist, die der Oberseite des dreieckförmigen Vorsprungs 10 und der Vertiefung 11 an den Querseiten von Einsatz 3 und Formrahmen 6 entspricht. Der untere Bereich des Vorsprungs 10 und der Vertiefung 11 wird durch je eine vertikal verlaufende Fläche 20 gebildet, die sich an die schrägen Flächen 19 anschließen. Die Befestigung mittels Druckstücke 15 und Schrauben 16 kann an den beiden Längsseiten entfallen. Dadurch können Material- und Herstellungskosten eingespart werden. Durch Abschrauben der Druckstücke 15 an den Querseiten des Formrahmens 6 kann der Einsatz 3 nach unten aus dem Formrahmen 6 herausgenommen werden.For the two long sides of the mold frame 6 and the insert 3, which, in contrast to the two transverse sides, do not have to transmit any forces when the mold is raised, it is sufficient if only a damping plate 12 is inserted on the top of the projection 10 and the recess 11 (FIG 4). The forces for clamping the insert 6 on the vibrating table 1 are thus transmitted via the damping plates 12 to the insert 6 and the holder 7. In this case, it is also not necessary to form the projection 10 and the depression 11 as triangularly as on the transverse sides. It is sufficient if the top of the projection 10 and the recess 11 has an inclined surface 19 which corresponds to the top of the triangular projection 10 and the recess 11 on the transverse sides of the insert 3 and the mold frame 6. The lower region of the projection 10 and the depression 11 is formed by a vertically running surface 20, which adjoin the inclined surfaces 19. The attachment by means of pressure pieces 15 and screws 16 can be omitted on the two long sides. This can save material and manufacturing costs. By unscrewing the pressure pieces 15 on the transverse sides of the mold frame 6, the insert 3 can be removed downward from the mold frame 6.

Die Dämpfungsplatten 12 und 13 können aus Gummi oder Kunststoff oder einem anderen elastischen Material bestehen. Anstelle der Dämpfungsplatten 12 und 13 können auch andere Dämpfungsmittel, beispielsweise Federn verwendet werden, die lösbar oder fest am Einsatz 3 und/oder am Formrahmen 6 befestigt oder geklemmt sind.The damping plates 12 and 13 can be made of rubber or plastic or another elastic material. Instead of the damping plates 12 and 13, other damping means, for example springs, can be used, which are detachably or firmly attached or clamped to the insert 3 and / or to the mold frame 6.

In einer anderen Ausführungsform der Erfindung kann sich selbstverständlich der dreieckförmige Vorsprung 10 und die dreieckfömige Vertiefung 11 sowohl an den Querseiten als auch an den Längsseiten des Einsatzes 3 und des Formrahmens 6 über deren gesamten Umfang ohne Unterbrechung erstrecken. Dabei können an allen Seiten des Formrahmens 6 die Druckstücke 15 zum Einspannen der Dämpfungsplatten 12, 13 vorgesehen sein. Anstelle der Druckstücke 15 kann die dreieckförmige Vertiefung 11 auch in die Innenseiten des Formrahmens 6 eingearbeitet sein. In diesem Falle muß der Formrahmen 6 zur Aufnahme des Einsatzes 3 durch Schraubverbindungen lösbar sein.In another embodiment of the invention, the triangular projection 10 and the triangular depression 11 can of course extend without interruption over their entire circumference both on the transverse sides and on the longitudinal sides of the insert 3 and the mold frame 6. The pressure pieces 15 can be provided on all sides of the mold frame 6 for clamping the damping plates 12, 13. Instead of the pressure pieces 15, the triangular depression 11 can also be worked into the inside of the mold frame 6. In this case, the mold frame 6 for receiving the insert 3 must be detachable by screw connections.

Anstelle des dreieckförmigen Querschnitts des Vorsprunges 10 und der Vertiefung 11 können auch andere geometrische Querschnittsformen wie z.B. rechteckförmige, halbkreisförmige und andere Klemmquerschnitte verwendet werden. Wesentlich dabei ist, daß die Querschnitte zwei oder mehr Seiten aufweisen, die bei Krafteinwirkungen durch den Rüttelantrieb oder bei Krafteinwirkungen durch das Hochfahren der Form (Ausschalen des Betonteils) die entstehenden Kräfte vom Einsatz auf den Formrahmen und ungekehrt in der X-, Y- und Z-Richtung übertragen können.Instead of the triangular cross-section of the projection 10 and the recess 11, other geometric cross-sectional shapes such as e.g. rectangular, semicircular and other clamping cross-sections can be used. It is essential that the cross-sections have two or more sides, the forces arising from the use of the form frame and inversely in the X-, Y- and Z direction can transmit.
