Description

Bei Grubens:tempaln aus Metall, die aus teleskopärtig ineinander geführten 'Rohren bestehen, ist esnotwendig, einen Anschlag vorzusehen:, der das Herausziehen des Oberstempels aus dem Unter-. stempel verhindert. Zu diesem Zweck wurde bereits vorgeschlagen, eine im Oberstempel eingeschweißte Bodenplatte und eine im Zwischenrohr oder Ünterstempcl eingeschweißte Platte durch eine Sicherungsstange zu verbinden, die für die größte ausziehbare Länge als Begrenzung dient. Ausführunr gen dieser Art sind schwer und teuer.At Grubens: tempaln made of metal, those made of telescopically guided one into the other 'Pipes exist, it is necessary to provide a stop: that allows pulling out of the upper stamp from the lower. stamp prevented. To this end it has already been proposed a base plate welded into the upper punch and one in the intermediate tube or to connect the welded plate with a locking bar, which serves as a limit for the greatest extendable length. Executions of this Kind are heavy and expensive.

Die Erfindung betrifft demgegenüber eine Sicherung zum Festhalten des Erreichung seiner größten Ausziehlänge, die sich durch Einfachheit, geringe Kosten. und geringen Gewichtsaufwand auszeichnet. Erfindungsgemäß - ist: der: Oberstempel, vorzugsweise am Ende des Gewindes, mit einer Eindrehung versehen, in die ein unter Federdruck stehender Bolzen einrastet. Eindrehung und Bolzen können gegebenenfalls auch zwei- oder mehrfach vorgesehen sein. Der Bolzen besitzt eine solche Breite, daß er ohne Hemmung über die Gewindevorsprünge des Oberstempedrohres zu gleiten vermag. Er kann sowohl im Führungsring des Stempels als auch am oberen Ende des -Unterstempelrohres angeordnet sein.In contrast, the invention relates to a securing device for holding on des achievement of its greatest extension length, which is characterized by simplicity, low Costs. and low weight. According to the invention - is: the: upper punch, preferably at the end of the thread, provided with a recess in which a lower The spring-loaded bolt engages. Turning and bolts can if necessary also be provided two or more times. The bolt has such a width that it can slide over the thread projections of the upper temp tube without any inhibition able. It can be placed in the guide ring of the punch as well as at the upper end of the Be arranged lower stamp tube.

In der Zeichnung ist eine beispielsweise- Ausführungsform des Erfindungsgegenstandes dargestellt. Abb. i zeigt einen Grubenstempel im Längsschnitt; Abb. z ist ein Schnitt nach der Linie A-B in Abb. .i, Abb. 3 eine vergrößerte Darstellung der Bolzenanordnung-irri Querschnitt.In the drawing is an example embodiment of the subject matter of the invention shown. Fig. I shows a pit punch in longitudinal section; Fig.z is a section according to the line A-B in Fig. .i, Fig. 3 an enlarged representation of the bolt arrangement-irri Cross-section.

Wie aus den. Abbildungen ersichtlich ist, besitzt das Oberstempelrohr i am Ende seines Außen-'gewändes eine Eindrehung a, während im Führungsring 3 ein Bolzen 4 angeordnet ist, der unter der Wirkung einer Schraubenfeder 5 steht, die ihn gegen das Oberstempelrohr i drückt. Die Breite des Bolzens 4 ist so gewählt, daß er ohne Hemmung über das Gewinde des Oberstempelrohres gleitet. Ist düse größte Ausziehlänge des Stempels erreicht, so rastet der Bolzen. 4 unter dem Druck der Feder 5 in die Eindrehung z und hält damit den Oberstempel fest. Die Eindrehung ist an ihrem oberen Ende konisch ausgebildet, so daß der Bolzen beim Rauben -des- Stempels ohne Schwierigkeit zurückgedrückt werden kann.As from the. As can be seen in the figures, the upper punch tube has i at the end of its outer-'gewändes a recess a, while in the guide ring 3 a Bolt 4 is arranged, which is under the action of a coil spring 5, the presses it against the upper punch tube i. The width of the bolt 4 is chosen so that it slides over the thread of the upper punch tube without inhibition. Is nozzle largest When the plunger has reached the pull-out length, the bolt engages. 4 under the pressure of Spring 5 into the recess z and thus holds the upper punch in place. The turning is conical at its upper end, so that the bolt when stealing -the- Stamp can be pushed back without difficulty.
