Description
Die Erfindung bezieht sich auf mehrteilige eiserne Grubenstempel, bei denen ein mit zwei oder mehreren durchgehenden Schlitzen versehener Oberstempel mittels Reibungsschlusses mit einem Unterstempel derart verbunden ist, daß die Klemmbacken durch einen in vertikaler Richtung sich bewegenden selbsthemmenden oder nicht selbsthemmenden Keil gespannt werden, der wiederum durch einen den Ober- und Unterstempel durchdringenden selbsthemmenden Querkeil verriegelt bzw. gelöst wird.The invention relates to multi-part iron pit punches, in which an upper punch provided with two or more continuous slots is connected by means of frictional engagement with a lower punch in such a way that the clamping jaws by a self-locking or non-self-locking one moving in the vertical direction Wedge are clamped, which in turn by the upper and lower punch penetrating self-locking cross wedge is locked or released.
Gegenüber den bekannten Grubenstempeln wird nach dem Hauptpatent das Keilgetriebe so angeordnet, daß der unmittelbare Kraftfluß vom Oberstempel in den Unterstempel nicht unterbrochen wird und der Querkeil stets von der Stützlast entlastet bleibt.Compared to the well-known pit punches, according to the main patent, the Wedge gear arranged so that the direct power flow from the upper punch into the The lower punch is not interrupted and the cross wedge is always relieved of the vertical load remain.
Die Erfindung gibt eine weitere Ausführungsform dieses Grundgedankens wieder und besteht darin, daß der zum Spannen und Lösen dienende Keil seine Widerlager einerseits an den Klemmbacken, andererseits an dem die Klemmbacken auseinandertreibenden Keil hat.The invention provides a further embodiment of this principle again and consists in the fact that the wedge used for tensioning and releasing is its abutment on the one hand on the clamping jaws, on the other hand on the one driving the clamping jaws apart Has wedge.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Es zeigt Abb. i einen lotrechten Schnitt einer Ausführungsform gemäß der Erfindung nach der Linie I-I der Abb. 3, Abb. 2 einen lotrechten Schnitt der gleichen Ausführungsform nach Linie II-II der Abb. 3, . Abb. 3 einen Querschnitt nach Linie III-III der Abb. i.In the drawing is an embodiment of the inventive concept shown. It shows Fig. I a vertical section according to an embodiment of the invention along the line I-I of Fig. 3, Fig. 2 is a vertical section of the same embodiment according to line II-II of Fig. 3,. Fig. 3 is a cross section according to line III-III of Fig. i.
An dem aus einem - Rohr bestehenden Unterstempel i ist die Schloßhülse 9 mit der Brücke 3 angeschweißt. Auf der Brücke 3 ruhen die beiden Klemmbacken 7, die den aus zwei Winkeleisen bestehenden Oberstempel 8 gegen die Schloßhülse 9 pressen, und zwar über den Keil 5 und den Querkeil q.. Der Querkeil q. wird zwischen den Keil 5 und die Ansätze 3o der Klemmbacken 7 getrieben. Durch diese Anordnung wird der Kraftfluß vom Oberstempel über die Klemmbacken 7 unmittelbar auf die Brücke 3 und den Unterstempel i geleitet. Nur ein geringer Teil der Kraft, die auf den Keil 5 wirkt, wird von dem Querkeil 4 aufgenommen.The lock sleeve is on the lower punch i, which consists of a tube 9 welded to the bridge 3. The two clamping jaws 7 rest on the bridge 3, which press the upper punch 8, which consists of two angle irons, against the lock sleeve 9, namely over the wedge 5 and the cross wedge q .. The cross wedge q. is between the Wedge 5 and the approaches 3o of the jaws 7 driven. This arrangement will the power flow from the upper punch via the clamping jaws 7 directly to the bridge 3 and the lower punch i. Only a small part of the force exerted on the Wedge 5 acts, is taken up by the transverse wedge 4.
