Description

Grubenstempel Es sind Grubenstempel bekannt, die aus einem parallelflächigen Außen- und Innenstempel bestehen. Es ist des weiteren bekannt, den Innenstempel mittels Exzenters gegen den Außenstempel anzupressen. Die sog. Exzenterstempel -,weisen den Nachteil auf, daß sich die Exzenter mit steigendem Gebirgsdruck derart festdrücken, daß sie nur schwierig gelöst und geraubt werden können.Pit stamps Pit stamps are known which consist of a parallelepiped Outside and inside stamp exist. It is also known, the inner stamp to be pressed against the outer punch by means of an eccentric. The so-called eccentric stamps - point the disadvantage that the eccentrics press so tight with increasing rock pressure, that they are difficult to solve and steal.

Die Erfindung betrifft einen Grubenstempel, dessen parallelflächiger Innenstempel mittels Exzenters gegen den Außenstempel preßbar ist, und besteht darin, daß zwischen Exzenter und Innenstempel eine parallelflächige Rutschplatte angeordnet wird, die im Abstand von dem Exzenter durch einen im Außenstempel vorgesehenen Schraubenbolzen ebenfalls gegen den Innenstempel anpreßbar ist.The invention relates to a pit punch, the parallelepiped Inner punch can be pressed against the outer punch by means of an eccentric, and consists in that a parallel slide plate is arranged between the eccentric and the inner punch at a distance from the eccentric by a screw bolt provided in the outer punch can also be pressed against the inner punch.

Die Vorteile der Erfindung sind darin zu sehen, daß der Grubenstempel nach der Erfindung aus parallelflächigen Ober- und Unterstempeln besteht, deren Exzentervorrichtung zum Rauben der Stempel lösbar ist. Hierbei kann das Lösen im Abstand vom Stempel aus .einer unfallsicheren Stellung heraus erfolgen. Der Lösevorgang kann dabei erschütterungsfrei vor sich gehen, zumal die Schraube nur auf Druck und nicht auf Abscherung beansprucht wird sowie mehrere Gewindegänge besitzen kann. Durch die Lokkerung der Schraube erfolgt ein Schwenken der Druckplatte um den Exzenterscheitel und dadurch eine Lockerung des Stempels, die durch den Gebirgsdruck zum vollkommenen Lösen führen kann, wenn der Exzenter durch die Schwenkbewegung der Druckplatte über den Scheitelpunkt geschoben wird.The advantages of the invention can be seen in the fact that the pit punch according to the invention consists of parallel upper and lower punches, their Eccentric device for stealing the stamp is releasable. Here, the solving in Distance from the stamp from .ein an accident-proof position. The solving process can be vibration-free, especially since the screw only applies pressure and is not subject to shear stress and can have several threads. Loosening the screw causes the pressure plate to pivot around the apex of the eccentric and thereby a loosening of the stamp, which is perfected by the pressure of the mountains Loosening can result if the eccentric is over due to the pivoting movement of the pressure plate the vertex is pushed.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt. Es zeigen Fig. i einen Längsschnitt des Außenstempels.In the drawing is an embodiment of the subject matter of the invention shown. FIG. 1 shows a longitudinal section of the outer die.

Fig. z einen Querschnitt des Außenstempels, Fig. 3 eine Ansicht des Außenstempels. Der parallelflächige Außenstempel i ist mit dem. schwenkbar gelagerten Exzenter q. und im Abstand hiervon angeordnetem Schraubengewinde für die Schraube 6 versehen. Das Andrücken des ebenfalls parallelflächigen Innenstempels 2 erfolgt durch den Exzenter q.. Zwischen Exzenter und Innenstempel ist die Rutschplatte 3 angeordnet, die im Abstand von dem Exzenter q. ebenfalls gegen den Innenstempel angepreßt wird. Steht der Stempel unter Druck und soll er geraubt werden, so wird zunächst die Schraube 6 gelöst, worauf die Rutschplatte 3 eine Schwenkbewegung ausführt und hierdurch den Stempel löst.Fig. Z is a cross section of the outer die, Fig. 3 is a view of the Outside stamp. The parallel outer punch i is with the. pivoted Eccentric q. and at a distance therefrom arranged screw thread for the screw 6 provided. The inner punch 2, which is also parallel-faced, is pressed on through the eccentric q .. between the eccentric and the inner punch is the slide plate 3 arranged, which q at a distance from the eccentric. also against the inner stamp is pressed. If the stamp is under pressure and should it be stolen, it will first loosened the screw 6, whereupon the slide plate 3 executes a pivoting movement and thereby releases the stamp.
