Abstract

The invention relates to a method for producing building bricks, in particular sand-lime bricks, in a press having an upper and lower ram, between which the filling mass is filled into the mould, in which method spikes penetrate into the mould through one ram so as to form cavities in the green brick. The spikes move into the mould only after it has been completely filled with filling mass. Thereafter, the rams produce the pressing force.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Bausteinen insbesondere von Kalksandsteinen in einer Presse mit Ober- und Unterstempel, zwischen denen die Füllmasse in die Form gefüllt wird, wobei durch einen Stempel hindurch Dorne in die Form dringen, um Hohlräume im Formling zu bilden.The invention relates to a method for producing Building blocks in particular of sand-lime bricks in a press with upper and lower stamp, between which the filling compound is filled into the mold, using a stamp penetrate thorns into the mold to create cavities in the Form to form.

Bei hydraulischen Pressen zum Herstellen von Bausteinen ist es bekannt, durch den Unterstempel hindurch Dorne in die leere Form fahren zu lassen und danach die verbleibenden Räume zwischen den Dornen mit Füllmasse auszufüllen und dann die Stempel den Preßdruck erzeugen zu lassen. Dies kann dazu führen, daß die oft recht engen Zwischenräume zwischen den Dornen nicht immer ausreichend verfüllt werden und damit nach dem Verpressen unerwünschte Hohlräume oder Stellen geringerer Dichte im Baustein verbleiben.With hydraulic presses for the production of building blocks it is known to thorn in through the lower stamp to let the empty form go and then the remaining spaces between the thorns with filling compound fill out and then the stamp generate the pressure allow. This can lead to the often very tight Gaps between the thorns are not always sufficient be filled and thus undesirable after pressing Cavities or places of lower density in the block remain.

Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art so zu verbessern, daß ein gleichmäßiges Verfüllen der Form gewährleistet ist. The object of the invention is a method of the beginning to improve the type mentioned so that a uniform Filling the form is guaranteed.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Dorne erst nach dem vollständigen Verfüllen der Form mit Füllmasse in die Form einfahren und danach die Stempel den Preßdruck erzeugen.This object is achieved in that the Spikes only after the mold has been completely filled with Insert the filling compound into the mold and then the stamp Generate pressure.

Da während des Verfüllens die Dorne noch nicht oder nur zum Teil in die Form eingefahren sind, kann eine sehr gleichmäßige Füllung bei hohem Füllgrad erreicht werden. Die danach einfahrenden Dorne erzeugen dann eine erste Verdichtung und dann wird der Preßdruck durch den oder die Stempel erzeugt.Because during the filling the thorns are not or only partially retracted into the mold can be very uniform filling with a high degree of filling can be achieved. The the mandrels that then move in create a first one Compression and then the pressing pressure by the or Stamp created.

Damit wird dem Fachmann ein Verfahren an die Hand gegeben, das zu Bausteinen hoher und gleichmäßiger Dichte führt. Besonders vorteilhaft ist es, wenn die Dorne über einen Trägerrahmen hydraulisch eingefahren werden. Auch können die Dorne in Relativbewegung zum Unter- bzw. Oberstempel in die Form eingefahren werden.This gives the person skilled in the art a method that leads to building blocks of high and uniform density. It is particularly advantageous if the spikes over a Carrier frame can be retracted hydraulically. Can too the mandrels in relative movement to the lower or upper stamp be retracted into the mold.

Ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens wird im folgenden näher beschrieben:An embodiment of the method according to the invention is described in more detail below:

Das Verfahren wird vorzugsweise auf einer hydraulischen Presse durchgeführt, die einen Oberstempel und Unterstempel besitzt, zwischen denen ein Formtisch die Form bildet. Der senkrecht bewegliche Unterstempel ist von senkrechten Dornen durchdrungen, deren Anzahl und Größe den gewünschten Hohlräumen in den Bausteinen insbesondere aus Kalksandstein oder Yali entsprechen.The process is preferably carried out on a hydraulic Press carried out an upper stamp and lower stamp has, between which a molding table forms. The vertically movable lower stamp is of vertical Pierced thorns, the number and size of which you want Cavities in the building blocks, in particular made of sand-lime brick or Yali.

Die Form wird verfüllt, während die beiden Stempel noch auseinandergefahren sind und die Dorne in die Form noch nicht oder nur zum Teil eindringen und somit ihr oberes Ende mit der Oberseite des Unterstempels abschließen oder etwas vorstehen. Danach werden die Dorne über einen Trägerrahmen hydraulisch hochgefahren, um in die noch nicht verdichtete Masse einzudringen. Erst darauf erzeugen beide Stempel den erforderlichen Preßdruck. Die Dorne können in Relativbewegung zum Unter- bzw. Oberstempel in die Form eingefahren werden.The mold is filled in while the two stamps are still there have come apart and the mandrels are still in shape not or only partially penetrate and thus their upper end finish with the top of the lower stamp or something protrude. Then the mandrels are placed over a support frame hydraulically ramped up to the not yet compressed  Penetrate mass. Only then do both stamps generate the required pressure. The thorns can be in Relative movement to the lower or upper stamp in the form be retracted.

Die so hergestellten Rohlinge werden aus der Presse herausgebracht und dann noch einer Dämpfhärtung unterzogen.The blanks produced in this way are removed from the press brought out and then subjected to steam curing.
