Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Abstechen des Randes von ovalen Blechdosen, die an jeder Drehbank angewendet werden kann und Sondermaschinen überflüssig macht.The invention relates to a device for parting the edge of oval tin cans that can be used on any lathe and special machines makes redundant.

Die Vorrichtung besteht im wesentlichen in der besonderen Ausbildung der Drehbank- und Reitstockspindel zu einer der Dosenform angepaßten Einspannvorrichtung für das Werkstück, die dann auch gleichzeitig die Zwangsführung für den Stahlhalter nach Art von Unrunddrehbänken bildet.The device consists essentially in the special design of the lathe and tailstock spindle to a jig adapted to the can shape for the Workpiece, which then also has the positive guidance for the steel holder after Kind of non-circular lathes.

In der Zeichnung ist die Vorrichtung beispielsweise unter Fortfall der bekannten Einrichtungen einer Drehbank dargestellt. Abb. 1In the drawing, the device is, for example, omitting the known devices shown on a lathe. Fig. 1

zeigt eine Aufsicht und Abb. 2 eine Stirnansicht. Die Einspannvorrichtung für die Dosen wird von der Drehbank- und Reitstockspindel gebildet.shows a plan view and Fig. 2 is a front view. The jig for the cans is formed by the lathe and tailstock spindle.

Auf der Drehbankspindel α einer Drehbank ao ist ein zylindrischer Körper aufgeschraubt, dessen Kopf b einen ovalen Querschnitt und eine gleichartige, zur Aufnahme der Blechdose c dienende Aussparung bt besitzt. Der untere Support d, der in bekannter Weise auf dem Längsschlitten e der Drehbank angeordnet ist, ist quer zur Bank verschiebbar und trägt eine Gleitrolle f, die auf dem Kopf b gleitet. Um dieses zu ermöglichen, wird zunächst die bekannte Schaltspindel im Sup-A cylindrical body is screwed onto the lathe spindle α of a lathe ao, the head b of which has an oval cross-section and a similar recess b t serving to accommodate the tin can c . The lower support d, which is arranged in a known manner on the longitudinal slide e of the lathe, is displaceable transversely to the bench and carries a roller f which slides on the head b. To make this possible, the known switching spindle in the sup-
