Description

Nachgiebiger Grubenstempel Das Hauptpatent 703 o64 bezieht sich auf einen nachgiebigen Grubenstempel aus zwei ineinander verschiebbaren und gegeneinander durch einen ringförmigen, aus Segmenten bestehenden Bremskörper feststellbaren Rohren, der an seinen beiden Enden kegelförmige Angriffsflächen für den Außenstempel und einen besonderen A.npreßring hat. Der Außenstempel ist an seinem oberen Ende kegelförmig verjüngt und der ringförmige Bremskörper an seinem dem Außenstempel abgewandten Ende zu einem Hohlkegel @erweitert und von einem die Segmente umschließenden Ring umgeben.Resilient pit punch The main patent 703 o64 refers to a resilient pit punch made of two mutually displaceable and against each other by means of a ring-shaped brake body consisting of segments lockable tubes, the conical contact surfaces for the outer die and at both ends has a special compression ring. The outer die is conical at its upper end tapered and the annular brake body facing away from the outer punch End to a hollow cone @expanded by a ring surrounding the segments surround.

Vorliegende Erfindung betrifft nun eine weitere Ausgestaltung und Verbesserung des Grubenstempels nach dem Hauptpatent. Der Stempel nach der Erfindung kennzeichnet sich dadurch, daß nur ein,die Bremssegmente umschließender ringförmiger Körper vorgesehen ist, der ,als Schelle ausgebildet ist, deren nach außen abgebogene Enden durch einen Spannrahmen mit einer Öffnung von nach unten zunehmender Breite zusammenpreßbar sind. Durch zweckmäßige Bemessung der Rahmenöffnung läßt sich eine große Übersetzung zwischen den Verschiebewegen des Rahmens und den gegeneinandergerichteten Bewegungen der. vorstehenden Enden des ringförmigen Körpers verwirklichen, so daß man durch Ausübung verhältnismäßig geringer Kräfte auf den Rahmen die vorstehenden Enden der Schelle mit sehr großer Gewalt gegeneinanderziehen kann. Auf diese Weise kann durch den mit dem Setzen der Stempel befaßten Bergmann durch Schläge mit dem Hammer auf den Rahmen der notwendige Widerstand des Stempels gegen den Druck des Hangenden schnell und sicher herbeigeführt werden.The present invention now relates to a further embodiment and Improvement of the pit stamp according to the main patent. The stamp according to the invention is characterized in that only one, the brake segments enclosing annular Body is provided, which is designed as a clamp, the bent outward Ends by a tenter frame with an opening of increasing width downwards are compressible. Appropriate dimensioning of the frame opening can be a large translation between the displacement paths of the frame and those directed against each other Movements of the. Realize protruding ends of the annular body, so that the above by exerting relatively small forces on the frame Can pull the ends of the clamp against each other with great force. In this way can by the miner involved in setting the stamps by blows with the Hammer on the frame the necessary resistance of the stamp to the pressure of the Hanging walls can be brought about quickly and safely.

An - sich sind rohrförmige Schellen mit nach außen umgebogenen Enden und einem diesen Enden zugeordneten Rahmen mit einer Öffnung zunehmender Breite nicht mehr neu. Man hat solche Schellen mit Rahmen bereits bei Grubenstempeln der Bauart zur Anwendung gebracht, bei denen der ringförmige, als Schelle ausgebildete Körper unmittelbar auf den Innenstempel aufpreßbar ist und sich auf einer Stirnfläche des Außenstempels abstützt.Per se are tubular clamps with ends bent outwards and a frame associated with these ends and having an opening of increasing width not new anymore. Such clamps with frames are already used in the pit stamps Type applied in which the ring-shaped, designed as a clamp Body can be pressed directly onto the inner punch and is located on an end face the outer ram is supported.
