Description
Hydraulischer Grubenstempel Die Erfindung betrifft einen hydraulischen Grubenstempel, der einen Innenstempel und einen ihm gegenüber axial geführten Außenstempel aufweist. Dabei ist der Innenstempel unten mit Fuß, der Außenstempel oben mit dem Kopf des Grubenstempels versehen.Hydraulic pit ram The invention relates to a hydraulic one Pit punch, the one inner punch and one opposite to it axially guided outer punch having. The inner stamp is at the bottom with the foot, the outer stamp is at the top with the Head of the pit stamp provided.
Die Erfindung besteht darin, daß am Innenstempel am Einsteckende und in einem geeigneten Abstand vom Einsteckende Führungsringe befestigt sind, die auf der Innenfläche des Außenstempels gleitend geführt sind. Durch diese Anordnung ändert sich der Abstand der -Führungsringe während der Hubbewegung des Grubenstempels nicht; die beiden gegeneinander verschiebbaren Teile erfahren also ständig die gleiche Abstützung gegeneinander. Außerdem liegen die Führungsringe bei jeder Hublänge im Außenstempel geschützt.The invention consists in that on the inner punch at the insertion end and at a suitable distance from the insertion end guide rings are attached, which on the inner surface of the outer punch are guided in a sliding manner. This arrangement changes the distance between the guide rings does not change during the lifting movement of the pit punch; the two mutually displaceable parts thus constantly experience the same thing Support against each other. In addition, the guide rings are in the Outside stamp protected.
In der Zeichnung ist eine Ausführungsform des Erfindungsgedankens dargestellt.In the drawing is an embodiment of the inventive concept shown.
Man erkennt das Gehäuse 1 des Kopfteiles mit dem Deckelteil 1 a und dem Bodenteil 1 b. Die Ausführung dieses Kopfteiles ist für die Erfindung ohne Bedeutung. Der Kopfteil sitzt auf dem Außenstempel 2. In diesem ist der Innenstempel 3 mit dem Bodenteil 3 a angeordnet. Auf dem Innenstempel 3 sind die Führungen 3 d und 3 e befestigt. Die Führung 3 d liegt am Einsteckende des Innenstempels, die Führung 3 e in einem geeigneten Abstand davon, der so groß bemessen ist, daß auch bei voll ausgezogenem Grubenstempel eine sichere Führung zwischen Außenstempel und Innenstempel gewährleistet ist. Die Führungen 3 d und 3 e gleiten auf der Innenfläche 2 b des Außen-Stempels. Am unteren Ende des Außenstempels kann eine Dichtung 2a vorgesehen sein.You can see the housing 1 of the head part with the cover part 1 a and the bottom part 1 b. The design of this head part is of no importance for the invention. The head part sits on the outer punch 2. The inner punch 3 is in this with the bottom part 3 a arranged. On the inner punch 3, the guides 3 d and 3 e attached. The guide 3 d is at the insertion end of the inner punch, the guide 3 e at a suitable distance from it, which is dimensioned so large that even when fully With the pit punch pulled out, a safe guide between the outer punch and the inner punch is guaranteed. The guides 3 d and 3 e slide on the inner surface 2 b of the Outside stamp. A seal 2a can be provided at the lower end of the outer die be.
