Description
Die Erfindung stellt eine Vorrichtung dar, die es ermöglicht, den Grubenstempel nach dem Setzen mit möglichst großer Last gegen das Hangende zu treiben. Sie besteht aus einem im Oberstempel axial verschiebbaren Stempelkopf, der durch einen in vertikaler Ebene gebogenen Keil gespannt wird.The invention provides a device that makes it possible to To drive the pit ram against the hanging wall with the greatest possible load after setting. It consists of an axially displaceable punch head in the upper punch a wedge bent in a vertical plane is clamped.
Es ist bekannt, im Stempelkopf Vorspannkeile anzuordnen. Beim Durchbiegen oder Zusammenquetschen der Kappe erleidet ein gerader Keil eine Belastung durch die Kappe. Auch wird das Antreiben des geraden Keiles durch die Kappe erschwert bzw. verhindert.' Zur Vermeidung dieser Nachteile schlägt die Erfindung die Verwendung eines gebogenen Keiles vor. Bei der Anwendung eines solchen Keiles bleibt dieser trotz verformter Kappe immer leicht zugänglich.It is known to arrange prestressing wedges in the punch head. When bending or squeezing the cap, a straight wedge is stressed the cap. The cap also makes it difficult to drive the straight wedge or prevented. ' To avoid these disadvantages, the invention proposes the use of a curved wedge. When using such a wedge, it remains Always easily accessible despite the deformed cap.
In der Zeichnung ist die Erfindung an einem Beispiel erläutert. Sie zeigt einen Stempelkopf mit Spannkeil in Seitenansicht, teilweise im Schnitt.The invention is explained using an example in the drawing. she shows a punch head with clamping wedge in side view, partially in section.
Die Vorlastvorrichtung besteht aus einem Aufsatzstück oder Rohr i, das an dem Oberstempel befestigt wird. Hierdurch wird erreicht, daß sich die Vorlastvorrichtung einfach und zweckmäßig zusammenbauen läßt, unabhängig vom Grubenstempel, und eine wahlweise Herstellung von Grubenstern= peln mit oder ohne Vorlastvorrichtung möglich ist.The preload device consists of a top section or tube i, which is attached to the upper punch. This ensures that the preload device can be assembled easily and appropriately, regardless of the pit stamp, and one Optional production of pit stars with or without preload device possible is.
In dem Rohr i ist der Stempelkopf 3 axial verschiebbar angeordnet. Beide Teile i und 3 werden .von dem gekrümmten Keil 4 durchdrungen und gegeneinander verspannt. Sie sind untereinander ohne Zuhilfenahme von Ketten o. dgl. so verbunden, daß sie nicht verlorengehen können. Dies kann z. B. so geschehen, daß der Stempelkopf 3 aus zwei Teilen, z. B. der Kopfplatte 3' und der Führung 3", zusammengesetzt ist. Die Kopfplatte 3' und die Führung 3" werden nach Einlegen des Keiles 4 fest miteinander verbunden, z. B. durch eine Schweißnaht 5. Durch Ansätze 6 am Rohr i, welche in die Schlitze der Führung 3" für den Keil 4 eingreifen, wird die Ausschiebbarkeit des Stempelkopfes begrenzt.In the tube i, the punch head 3 is arranged to be axially displaceable. Both parts i and 3 are penetrated by the curved wedge 4 and against each other tense. They are connected to one another without the aid of chains or the like in such a way that that they cannot be lost. This can e.g. B. done so that the punch head 3 in two parts, e.g. B. the head plate 3 'and the guide 3 "is composed. The head plate 3 'and the guide 3 "are firmly together after inserting the wedge 4 connected, e.g. B. by a weld 5. By lugs 6 on the pipe i, which in the slots of the guide 3 ″ engage for the wedge 4, the extensibility becomes of the punch head limited.
