Description

Bei Grubenstempeln ist es bekannt, eine bewegliche Kronenplatte vorzusehen und diese mit dem Stempeldruckstück kugelpfannenartig zu verbinden, damit die Druckübertragung vom Hangenden auf den Stempel zentrisch herbeigeführt werden. kann und ein Ausknicken des Stempels vermieden wird. Auch wurde bereits vorgeschlagen, zwischen Kronenplatte und Stempel Gummieinlagen anzuordnen. Da die direkte Belastung von Gummieinlagen indessen zu Beanspruchungen dieses Werkstoffes führt, denen er auf die Dauer nicht gewachsen ist, haben sich diese Ausführungen nicht allgemein eingeführt. Sind Kronenplatte und Druckstück in weiterhin bekannter Weise nur in ihrem mittleren Teil durch Kugelflächen miteinander verbunden, so ist die Einstellung des Stempels .auch bei durch Verschmutzung vergrößerter Reibung noch sichergestellt.In the case of pit punches, it is known to provide a movable crown plate and to connect these with the stamp pressure piece in the manner of a ball socket, thus transferring the pressure be brought about centrically from the hanging wall on the punch. can and a buckling of the stamp is avoided. It has also already been suggested between the crown plate and to arrange stamp rubber inserts. Because the direct load on rubber inserts however, it leads to stresses on this material which it does not in the long term has grown, these explanations have not become generally established. Are crown plate and pressure piece in a known manner only in its central part by spherical surfaces connected to each other, the setting of the ram is also possible when it is dirty increased friction still ensured.

Der Erfindung liegt die Aufgabe zugrunde, die Lagerflächen zwischen Kronenplatte und Stempeldruckstück vor Verschmutzung zu schützen, stets eine auf die Rückführung der Kronenplatte in ihre Mittellage wirkende Kraft auf diese auszuüben und sie .gleichzeitig vor Verlust zu schützen. Erfindungsgemäß erfolgt dies dadurch, daß auf gegenüberliegenden Ringflächen von Kronenplatte und Druckstück ein ,diese verbindender, durch. Vulkanisation oder auf andere Weise befestigter Gummiring angeordnet ist. Dieser Gummiring kann zur zusätzlichen Druckaufnahme herangezogen werden und führt die Kronenplatte stets in die Mittelstellung zurück. Die Qualität des Gummis wird man so bemessen, daß er bei hohen Beanspruchungen seitlich ausweicht, also nicht zerstört wird. Er schließt die kugelpfannenartigen Lagerflächen vollständig nach außen hin ab, so daß diese gegen das Eindringen von Fremdkörpern sicher sind und auch das gegebenenfalls auf die Lagerflächen gebrachte Schmiermittel vor Verschmutzung geschützt wird.The invention is based on the object, the bearing surfaces between To protect the crown plate and the punch pressure piece from contamination, always have one on the return of the crown plate to its central position to exert a force acting on it and at the same time to protect them from loss. According to the invention, this is done by that on opposite annular surfaces of the crown plate and pressure piece one, this connecting, through. Vulcanization or otherwise attached rubber ring arranged is. This rubber ring can be used for additional pressure absorption and always returns the crown plate to the middle position. The quality of the rubber one is dimensioned in such a way that it gives way to the side under high loads, that is is not destroyed. It completely closes the spherical socket-like bearing surfaces towards the outside, so that they are safe against the ingress of foreign bodies and also the lubricant that may be applied to the bearing surfaces to prevent contamination is protected.

Um den Verlust der Kronenplatte und des Gummiringes bei einem Lösen der Vulkanisationsverbindung auszuschließen, kann zusätzlich zwischen Kronenplatte und Oberstempel ein Drahtnetz vorgesehen sein, das durch Punktschweißung oder ähnliche Maßnahmen mit diesen beiden Teilen verbunden ist: In der Zeichnung ist der Gegenstand der Erfindung in einer Abbildung im Querschnittdargestellt. Die Kronenplatte i ist in ihrem Mittelteil gallig ausgeführt und ruht kugelpfannenartig in einer entsprechenden Ausnehmung der Druckplatte :2 des Grubenstempels. In einer umlaufenden Ausnehmung von Kronenplatte und Druckstück ist ein Gummiring 3 gelagert, der mit beiden Teilen durch Vulkanisationoder auf ähnliche Weise verbunden ist. Um eine gute Bewegungsmöglichkeit zwischen Kronenplatte und Druckstück zu erreichen, wird man die kugelpfannenartige Lagerfläche im Durchmesser klein halten und durch Härtung der Auflagerungsstellen die erforderliche Kraftaufnahmefähigkeit sicherstellen. Der Gummiring 3 schützt die Lagerstellen vor Verschmutzung, die Kronenplatte vor Verlust und führt letztere stets in ihre Mittellage zurück. Als weiterer Schutz vor Verlust und Verschmutzung ist zwischen Kronenplatte i und Druckstück ein Drahtnetz 4 vorgesehen, das vorteilhafterweise durch Punktschweißung seit Kronenplatte und Oberstempelrohr 5 verbunden ist.About the loss of the crown plate and the rubber ring in the event of loosening Exclude the vulcanization connection, can also be placed between the crown plate and upper punch a wire mesh can be provided by spot welding or the like Measures associated with these two parts: In the drawing is the object of the invention shown in a figure in cross section. The crown plate i is executed biliously in its middle part and rests like a ball socket in a corresponding one Recess of the pressure plate: 2 of the pit punch. In a circumferential recess of the crown plate and pressure piece, a rubber ring 3 is mounted, which with both parts by vulcanization or the like. To be able to move freely To achieve between crown plate and pressure piece, one becomes the spherical socket-like Keep the diameter of the bearing surface small and harden the support points ensure the necessary force absorption capacity. The rubber ring 3 protects the bearings from contamination, the crown plate from loss and leads the latter always back to their central position. As further protection against loss and contamination a wire mesh 4 is provided between the crown plate i and pressure piece, which advantageously is connected by spot welding since the crown plate and upper punch tube 5.
