Abstract

The invention relates to a vibration compression system for compressing and shaping molding materials into shaped bodies having a circumference and a length. Said molding materials are shaped in mold recesses of molding boxes. An outer unbalanced body (1) and an inner unbalanced body (2) having the same kinetic momentum are arranged one inside the another in a sleeve-like manner. The centers of gravity of both unbalanced bodies (1, 2) lie in a rotational plane. An adjusting bushing (7) permits the angular position of the centers of gravity to vary in relation to one another, and the shaft (3) is not subjected to stresses caused by bending due to the centrifugal force of the unbalanced bodies (1, 2).

Description

VIBRATIONS-VERDICHTUNGSSYSTEM ZUM VERDICHTEN VON FORMMASSEN IN FORMKÄSTEN UNTER VERWENDUNG ZWEIER UNWUCHTKÖRPER VIBRATION COMPRESSION SYSTEM FOR COMPRESSING MOLDING MATERIALS IN MOLDING BOXES USING TWO BALANCERS
Die Erfindung betrifft ein Vibrations-Verdichtungssystem zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen zu Formkörpem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a vibration compression system for compressing and shaping molding compositions in mold recesses from molding boxes to moldings according to the preamble of claim 1.
Es ist bekannt, daß Verdichtungssysteme zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen zu Formkörpern aus mehreren Unwuchtmassen bestehen. Die Unwuchtmassen sitzen auf einer Welle, die eine Rotation dieser Unwuchtmassen erzeugt, wobei jede der Unwuchtmassen eine ungerichtete Einzelfliehkraft in Abhängigkeit von der Winkelgeschwindigkeit der Welle erzeugt. Die Summe dieser Einzelfliehkräfte ergibt eine resultierende Vibratorfliehkraft. Diese resultierende Vibra- torfliehkraft wird über eine Welle auf Lager übertragen und über ein Vibratorgehäuse und einen Formkasten an einen Formköφer abgegeben. Durch Änderung der Schwerpunktlage der Unwuchtmassen zueinander kann die Größe der resultierenden Vibratorfliehkraft geändert werden. Für bestimmte Einsatzfälle kann eine Verstellung von Null bis zur maximalen Fliehkraft bei laufendem Vibrator erforderlich sein. Die Wirkrichtung der resultierenden Vibratorfliehkraft ist dabei nicht einstellbar.It is known that compression systems for compressing and shaping molding compounds in molding recesses from molding boxes to shaped bodies consist of several unbalanced masses. The unbalanced masses sit on a shaft which produces a rotation of these unbalanced masses, each of the unbalanced masses generating an undirected centrifugal force depending on the angular velocity of the shaft. The sum of these individual centrifugal forces results in a resulting vibrator centrifugal force. This resulting vibratory centrifugal force is transmitted to a bearing via a shaft and delivered to a molded body via a vibrator housing and a molded box. By changing the center of gravity of the unbalanced masses relative to each other, the size of the resulting vibratory centrifugal force can be changed. For certain applications, adjustment from zero to the maximum centrifugal force with the vibrator running may be required. The direction of action of the resulting vibrator centrifugal force is not adjustable.
In der DE-AS 20 46 245 ist ein Vibrationsantrieb beschrieben, der eine an sich nicht gewünschte Bewegungskomponente eines Exzenterantriebes möglichst weitgehend durch einen Schwingungskörper auffangen und in eine gewünschte Bewegungsrichtung transformieren soll. Diese Aufgabe wird dadurch gelöst, daß der Exzenterantrieb mit verstellbarem Hub in einem Gleitkörper angeordnet ist, der radial zu einem Schwenkzapfen verschiebbar in einer Öffnung des Schwingungskörpers angeordnet ist. Ein solcher Vibrationsantrieb erzeugt eine gerichtete Schwingung in nur einer Achse und soll als Rammvibrator das Eindringen einer Vorrichtung in die Erdoberfläche erleichtern.DE-AS 20 46 245 describes a vibration drive which is intended to largely catch a movement component of an eccentric drive that is not desired per se by means of a vibrating body and to transform it into a desired direction of movement. This object is achieved in that the eccentric drive is arranged with an adjustable stroke in a sliding body which is arranged so as to be displaceable radially to a pivot pin in an opening of the vibrating body. Such a vibration drive generates a directional vibration in only one axis and is intended to facilitate the penetration of a device into the earth's surface as a ramming vibrator.
Eine solche Lösung ist für ein Vibrations-Verdichtungssystem zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen nur für flache Formkörper mit einer Oberseite und mit einer Unterseite, aber nicht für Formköφer mit einem Umfang und mit einer Länge geeignet.Such a solution is suitable for a vibration compression system for compressing and molding molding compounds in the mold recesses of mold boxes only for flat moldings with a top and a bottom, but not for moldings with a circumference and with a length.
Darüber hinaus wird die Welle nicht nur durch die Übertragung der Rotationskräfte, sondern auch durch die Fliehkräfte der Unwuchtkörper beansprucht. - 2 -In addition, the shaft is not only stressed by the transmission of the rotational forces, but also by the centrifugal forces of the unbalance bodies. - 2 -
Aufgabe der in den Patentansprüchen 1 bis 3 angegebenen Erfindung ist die Entwicklung eines Vibrations-Verdichtungssystems zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen zu Formkörpern mit einem Umfang und mit einer Länge, überwiegend für ringförmige, runde oder ovale Formkörper oder vielkantige, komplexe Profile, bei dem die Welle zudem nicht durch die Fliehkräfte der Unwuchtkörper auf Biegung beansprucht wird.The object of the invention specified in claims 1 to 3 is the development of a vibration compression system for compressing and molding molding compounds in mold recesses from molded boxes to shaped bodies with a circumference and a length, predominantly for annular, round or oval shaped bodies or polygonal, complex profiles , in which the shaft is also not subjected to bending by the centrifugal forces of the unbalance bodies.
Diese Aufgabe wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst. In dem erfindungsgemäßen Vibrations-Verdichtungssystem zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen zu Formkörpern mit einem Umfang und mit einer Länge, überwiegend zu ringförmigen, runden oder ovalen Formkörpern, sind ein äußerer Unwuchtkörper 1 und ein innerer Unwuchtkörper 2 mit gleichem kinetischen Moment hülsenförmig so ineinander angeordnet, daß die Massenschwerpunkte beider Unwuchtkörper 1 , 2 in einer Rotationsebene liegen und die Änderung der Winkellage der Massenschwerpunkte zueinander mit einer Verstellbuchse 7 erfolgt und daß die Welle 3 frei von Biegebeanspruchungen durch die Fliehkraft der Unwuchtkörper 1 , 2 ist.This object is achieved by the features listed in claim 1. In the vibration compression system according to the invention for compressing and shaping molding compounds in mold recesses from molded boxes to shaped bodies with a circumference and with a length, predominantly annular, round or oval shaped bodies, an outer unbalance body 1 and an inner unbalance body 2 with the same kinetic moment are sleeve-shaped arranged so that the center of gravity of both unbalance bodies 1, 2 lie in a plane of rotation and the change in the angular position of the center of gravity relative to one another is carried out with an adjusting bush 7 and that shaft 3 is free of bending stresses due to the centrifugal force of unbalance bodies 1, 2.
Die Verstellbuchse 7 wird dabei entweder mit einem Gewinde und einer formschlüssigen Verbindung ausgeführt, wobei durch eine achsiale Verschiebung der Verstellbuchse 7 eine Relativbewegung der Unwuchtkörper 1 , 2 zueinander erreicht wird oder mit zwei- gegenläufigen Gewinden ausgeführt, so daß eine Relativbewegung der Unwuchtkörper 1 , 2 zueinander in der Art erzwungen wird, daß die Richtung der resultierenden Vibratorfliehkraft im Bezug auf die Welle 3 immer konstant bleibt.The adjusting bushing 7 is either carried out with a thread and a positive connection, whereby an axial movement of the adjusting bushing 7 achieves a relative movement of the unbalanced bodies 1, 2 to one another or is carried out with two opposite threads, so that a relative movement of the unbalanced bodies 1, 2 is forced towards each other in such a way that the direction of the resulting vibratory centrifugal force with respect to the shaft 3 always remains constant.
Zum Formen von langgestreckten Formkörpern wird in vorteilhafter Ausgestaltung der Erfindung einer Serie von mehreren Vibratoren durch Kopplung der Wellenenden 8, 8' hintereinander angeordnet und zentral angetrieben, wobei dann noch an jedem einzelnen Vibrator eine andere Fliehkraft einstellbar und jede Fliehkraft einzeln verstellbar ist.In an advantageous embodiment of the invention, a series of several vibrators is arranged one behind the other by coupling the shaft ends 8, 8 ′ and is driven centrally for forming elongate shaped bodies, a different centrifugal force then being adjustable on each vibrator and each centrifugal force being individually adjustable.
Die mit der Erfindung erreichten Vorteile bestehen insbesondere darin, daß die Masseschwerpunkte der Unwuchtkörper 1 , 2 damit in einer Rotationsebene liegen und eine mehrachsige Biegebeanspruchung der gelagerten Bauteile entfällt und daß die Welle 3 frei von Biegebeanspruchungen durch die Fliehkraft der Unwuchtkörper 1 , 2 ist. Die Ausführung der Verstellbuchse 7 mit 2 gegenläufigen Gewinden nach Patentan- - 3 - spruch 2 ermöglicht es, durch achsiale Verschiebung der Verstellbuchse 7 eine Relativbewegung der Unwuchtkörper 1 , 2 zueinander so zu erzwingen, daß die Richtung der resultierenden Vibratorfliehkraft im Bezug auf die Welle 3 immer konstant bleibt. Eine zusätzlich vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 3 angege- ben. Durch Kopplung der Wellenenden können mehrere Vibratoren hintereinander angeordnet werden und gleichzeitig betrieben werden. An jedem dieser Vibratoren ist eine andere Fliehkraft einstellbar und verstellbar. In Verbindung mit den Merkmalen nach Anspruch 2 ist es zum erstenmal möglich, die Richtung der resultierenden Vibratorfliehkraft im Bezug auf die Welle konstant einzustellen.The advantages achieved with the invention consist in particular in that the center of gravity of the unbalance bodies 1, 2 thus lie in a plane of rotation and there is no multi-axis bending stress of the mounted components and that the shaft 3 is free of bending stresses due to the centrifugal force of the unbalance bodies 1, 2. The design of the adjusting bush 7 with 2 counter-rotating threads according to patent - 3 - Say 2 makes it possible to force a relative movement of the unbalance bodies 1, 2 to one another by axial displacement of the adjusting bush 7 so that the direction of the resulting vibratory centrifugal force with respect to the shaft 3 always remains constant. An additional advantageous embodiment of the invention is specified in claim 3. By coupling the shaft ends, several vibrators can be arranged one behind the other and operated simultaneously. A different centrifugal force can be set and adjusted on each of these vibrators. In connection with the features of claim 2, it is possible for the first time to set the direction of the resulting vibratory centrifugal force with respect to the shaft constant.

Im Betrieb des Vibrations-Verdichtungssystems zum Verdichten und Formen von Formmassen in Formausnehmungen von Formkästen zu Formkörpern mit einem Umfang und mit einer Länge nach Fig. 1 und Fig. 2 wird ein Wellenende der Welle angetrieben und überträgt die Rotationsbewegung über das Vielkeilprofil der Welle formschlüssig an die Verstellbuchse. Die Verstellbuchse wiederum überträgt die Rotation über die beiden gegenläufigen Gewinde auf ihrer Außenfläche an beide Rotationskörper. Durch die achsiale Verschiebung der Verstellbuchse mittels der Versteileinrichtung nach Fig. 1 wird eine Relativbewegung der Unwuchtkörper und damit eine Änderung der Lage der Massenschwerpunkte zueinander erzwungen.In the operation of the vibration compression system for compressing and molding molding compounds in mold recesses from molding boxes to shaped bodies with a circumference and with a length according to FIGS. 1 and 2, a shaft end of the shaft is driven and transmits the rotational movement via the multi-spline profile of the shaft in a form-fitting manner the adjustment bush. The adjusting bush in turn transmits the rotation to the two rotating bodies via the two opposing threads on its outer surface. The axial displacement of the adjusting bush by means of the adjusting device according to FIG. 1 forces a relative movement of the unbalanced bodies and thus a change in the position of the center of gravity relative to one another.
Die Lage der Unwuchtkörper zueinander und die Relativbewegung der Unwuchtkörper beim Verstellvorgang sind unabhängig von der achsialen Lage und der Winkelgeschwindigkeit der Welle. Die Welle ist durch den Vibrator durchtreibend. Durch Kopplung der Wellenenden können mehrere Vibratoren hintereinander angeordnet werden. Sie können gleichzeitig betrieben werden. An jedem dieser Vibratoren ist eine andere Fliehkraft einstellbar und verstellbar.The position of the unbalanced bodies relative to one another and the relative movement of the unbalanced bodies during the adjustment process are independent of the axial position and the angular velocity of the shaft. The vibrator drives the shaft. By coupling the shaft ends, several vibrators can be arranged one behind the other. They can be operated at the same time. A different centrifugal force can be set and adjusted on each of these vibrators.
In einem typischen Anwendungsfall der Erfindung werden zur Herstellung von Betonrohren Vibrationskerne verwendet. Es werden nun mehrere der oben beschriebenen Vibratoren zu einem Zentralvibrator zusammengebaut. Die Vibration der Kerne wird durch diesen Zentralvibrator erzeugt, der aus mehreren einzelnen Vibratoren besteht, die miteinander verbunden sind und zentral angetrieben werden. In Anpassung an das herzustellende Produkt und in Abhängigkeit von dem jeweiligen Fertigungszeitpunkt, der Betonzusammensetzung, der Vibratordrehzahl (Erregerfrequenz) und des Feder-Dämpfer-Systems der Formeinrichtung/Maschine, wird während der Produktion eines Rohres die Vibratorfliehkraft jeder einzelnen Vibratoretage eingestellt bzw. verstellt. In a typical application of the invention, vibration cores are used for the production of concrete pipes. Several of the vibrators described above are now assembled to form a central vibrator. The vibration of the cores is generated by this central vibrator, which consists of several individual vibrators that are connected to each other and driven centrally. In adaptation to the product to be manufactured and depending on the respective time of manufacture, the concrete composition, the vibrator speed (excitation frequency) and the spring-damper system of the molding device / machine, the centrifugal vibratory force of each vibrator level is adjusted or adjusted during the production of a tube.
