KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Preßköpfe von Matrizen - Präge- und -Trockenpressen werden in der Bodenplatte
zur Abführung der während des Pressens gebildeten Dämpfe mit einer größeren Anzahl
von Löchern kleineren Durchmessers versehen. Die Herstellung derartiger Platten erfordert
größeren Zeitaufwand und ist mit nicht unerheblichen Kosten verknüpft; außerdem wird
die Platte durch die Löcher erheblich geschwächt. Würde man zur Erzielung der
gleichen Saugwirkung Bohrungen größeren Durchmessers · in größerem Abstand anwenden,
so würde das Preßgut in unzulässiger Weise in diese Bohrungen hineingedrückt werden.
Um diesem Übelstand abzuhelfen, werden nun gemäß der Erfindung in solche Bohrungen
der Preßplatte längsgebohrte Stöpsel eingesetzt, deren Bohrungen auf der Druckseite
in sich kreuzende Saugschlitze übergehen. The press heads of dies, embossing and drying presses are provided with a larger number of smaller-diameter holes in the base plate to discharge the vapors formed during pressing. The production of such plates requires a great deal of time and is associated with not inconsiderable costs; in addition, the plate is considerably weakened by the holes. If, in order to achieve the same suction effect, bores with a larger diameter were to be used at a greater distance, the material to be pressed would be pressed into these bores in an impermissible manner.
In order to remedy this inconvenience, according to the invention, longitudinally drilled plugs are inserted into such bores in the pressure plate, the bores of which merge into intersecting suction slots on the pressure side.
Auf beiliegender Zeichnung ist eine Ausführungsform des Preßkopfes zur Darstellung gebracht, und zwar zeigt:The accompanying drawing shows an embodiment of the press head, namely shows:
Fig. ι einen Höhenschnitt,Fig. Ι a vertical section,
Fig. 2 einen Schnitt durch einen der Stöpsel für sich undFig. 2 is a section through one of the plugs for itself and
Fig. 3 einen Grundriß des Stöpsels.Figure 3 is a plan view of the plug.
Der Hohlraum des Preßkopfes α ist in zwei Kammern getrennt, wovon die untere b zum Absaugen der Dämpfe und die obere c zum Anheizen dient. Selbstverständlich kann auch der Preßkopf mit nur einem Hohlraum versehen sein, in welchem Falle die untere Platte i beheizt wird. In der Bodenplatte des Preßkopfes α sind Löcher vorgesehen, ί die zur Aufnahme der Saugstöpsel e (Fig. 2 und 3) dienen, welche der Länge nach bis auf einen kleinen Abstand von der Saugfläche durchbohrt sind und unten in sich kreuzende Schlitze f übergehen. Diese Einschnitte sind < ganz schmal gehalten, so daß die untere Fläche g des Stöpsels dem Preßgut den erforderlichen Widerstand bietet und kein Eindrücken des Preßgutes in die Bohrungen stattfindet. ■ . ' . ■The cavity of the compression head α is divided into two chambers, of which the lower b is used for sucking off the vapors and the upper c is used for heating. Of course, the press head can also be provided with only one cavity, in which case the lower plate i is heated. In the bottom plate of the compression head α holes are provided, ί which serve to accommodate the suction plugs e (Fig. 2 and 3), which are drilled lengthwise except for a small distance from the suction surface and merge into intersecting slots f below. These incisions are kept very narrow so that the lower surface g of the plug offers the required resistance to the material to be pressed and the material to be pressed is not pressed into the bores. ■. '. ■
An den Hohlraum b ist noch das Saugrohr h angeschlossen.The suction pipe h is also connected to the cavity b.
