Description
Stell- und Liftvorrichtung für zweiteilige Grubenstempel Die vorliegende Erfindung betrifft eine Stell- und Liftvorrichtung für zweiteilige Grubenstempel ;nach Patent 484017. Die Vorrichtung nach dem Hauptpatent ist insbesondere bei solchen Stempeln zu verwenden, die aus Profileisen bestehen. Die Verwendung dieser Vorrichtung auch bei runden Stempeln, die z. B. aus nahtlosen Rohren bestehen, zu ermöglichen, ist der Zweck der vorliegenden Erfindung. Bei dieser neuen Stell- und Lüftvorrichtung ist die Wälzfläche der durch Federdruck in Pr.eßstellung gehaltenen Walze konkav, entsprechend der Rundung des aus einem Rohr bestehenden. Stempelteils, ausgebildet, wobei zur Führung dieser Walze auf der "geneigt stehenden Innenfläche des Schlosses, welche als Gegendruckfläche dient, ein wulstartiger Vorsprung von. rundem Querschnitt vorgesehen ist.Adjusting and lifting device for two-part pit punches The present one The invention relates to an adjusting and lifting device for two-part pit punches ; according to patent 484017. The device according to the main patent is particularly in those To use punches that consist of profile iron. The use of this device even with round stamps, the z. B. consist of seamless tubes to enable is the purpose of the present invention. With this new actuating and ventilating device the rolling surface of the roller held in the press position by spring pressure is concave, corresponding to the rounding of the existing tube. Stamp part, trained, whereby to guide this roller on the "inclined inner surface of the lock, which serves as a counterpressure surface, a bead-like projection of. round cross-section is provided.
In der Zeichnung ist ein Ausführungsbeispiel des Erfin3ungsgegenstandes in einem senkrechten Mittellängsschnitt (Abb. i) und im Grundriß (Abb.2) dargestellt.The drawing shows an embodiment of the subject matter of the invention shown in a vertical central longitudinal section (Fig. i) and in the plan (Fig. 2).
Auf dem aus einem 'Rohr bestehenden Unterstemp,ela ist der ebenfalls rohrförmige Oberstempel b verschiebbar und wind vorn dem Schloß c getragen. In dem Schloß iGt die als Pneßelement .dienende Walzed angeordnet, welche mit ihren Zapfen'! durch Schlitze k in .der Schloßwandung geführt ist. Die Wälz-Fläche dieser Walze ist konkav ausgebildet, so daß sie sich fest an den runden Unterstempel a anpaßt. Auf der als Gegendruckfläche -dienenden Innenwandung des Schlossfes ist ein wulstartiger Vorsprunge von rundem Querschnitt vorgesehen, welcher zur Führung der Walze dient. Vorteilhafberweise wird die Richtung der Schlitze wie auch der Innenwandung des Schlosses bzw. des Führungswulstes nach oben hin gegen den Unterstempel geneigt sein. Die Walze wird von Bäckchen f getragen, die durch Federn lz gegen die untere abnehmbare Wand g des Schlosses abgestützt sind.On the lower stamp, ela, which consists of a tube, the upper stamp b, which is also tubular, is displaceable and is carried at the front of the lock c. In the lock iGt the "serving as a Pneßelement Walzed" is arranged, which with its pin '! through slots k in .der lock wall is performed. The rolling surface of this roller is concave so that it adapts firmly to the round lower punch a. A bead-like projection of round cross-section is provided on the inner wall of the lock base, which serves as a counter-pressure surface and serves to guide the roller. Advantageously, the direction of the slots as well as the inner wall of the lock or of the guide bead will be inclined upwards towards the lower punch. The roller is carried by cheeks f , which are supported by springs lz against the lower removable wall g of the lock.
