Description

Vorrichtung zum gleichzeitigen Zerteilen von Glasrohren Die vorliegende Erfindung bezieht sich auf eine Vorrichtung, um Glasröhren an einer Anzahl von Stellen gleichzeitig zu zerteilen.Apparatus for the simultaneous cutting of glass tubes The present Invention relates to an apparatus for moving glass tubes at a number of locations to be divided at the same time.

Die Erfindung besteht darin, daß das Glasrohr, auf zwei parallelen, in gleichem Sinne umlaufenden, glatten. Metallwalzen liegend, an den zu zerteilenden Stellen von scharfen Stichflammen tangential bestrichen wird. Infolge der Umdrehung des. Glasrohres auf den Metallwalzen kommen die von den Flammen erhitzten Stellen unmittelbar darauf mit der kalten Metalloberfläche in Berührung, und es tritt schon nach ein- bis zweimaliger Umdrehung an den erhitzten Stellen ein glatter ringförmiger Sprung ein. Durch passende Wahl der Anzahl und der Stellung der Flamnien kann das Rohr in so viele Teile von vorgeschriebener Länge wie gewünscht in einem .Arbeitsgang zerlegt werden. Es wird nach der Erfindung also davon abgesehen, das Glasrohr an einem Ende in ein-Futter einzuspannen, wie es nach einem bekannten Vorschlage der Fall sein soll, was aber den Nachteil finit sich bringen würde, daß sich nur vollkommen gerade Glasrohre verarbeiten lassen, während eine gewisseKriimmung der üblichen Glasrohre die Regel ist. Die Erfindung schließt sich vielmehr an den. ebenfalls bekannten Vorschlag an, die zu zerteilenden Glasrohre zwischen Gruppen von. Scheiben zu lagern, wendet jedoch statt der Scheiben glatte- Walzen an und erzielt so gleichzeitig mit einer geeigneten Lagerung ein Abschrecken der Glasrohre durch die Lagerwalzen an denienigen Stellen. an denen ein Sprengen erfolgen soll.The invention consists in that the glass tube, on two parallel, in the same sense circumferential, smooth. Metal rollers lying on the one to be cut Sharp jets of flame are swept tangentially. As a result of rotation of the. Glass tube on the metal rollers come the places heated by the flames immediately afterwards in contact with the cold metal surface, and it already kicks off after turning once or twice a smooth ring-shaped one on the heated areas Jump in. This can be achieved through a suitable choice of the number and position of the flames Pipe into as many parts of the prescribed length as required in one operation be disassembled. According to the invention, therefore, the glass tube is not connected one end to be clamped in a chuck, as it was proposed by the Should be the case, which, however, would bring the disadvantage finite that only perfect Let straight glass tubes be processed, while a certain curvature of the usual Glass tubing is the rule. Rather, the invention follows the. Likewise known proposal to divide the glass tubes between groups of. Discs To store, however, uses smooth rollers instead of the discs and thus achieves at the same time with suitable storage, quenching of the glass tubes by the bearing rollers in some places. where blasting is to take place.

Die Vorrichtung nach der Erfindung besteht aus zwei parallelen glatten 'Metallwalzen, die auch in mehreren abwechselnd wirksam werdenden Paaren vorhanden sein können, die eine Rinne zur Aufnahme des zu schneidenden Glasrohres bilden und die, in gleichem Sinne umlaufend, das Glasrohr in Umdrehung versetzen. Um auch nicht ganz gerade Glasrohre verarbeiten zu können, befindet sich oberhalb der Walzen eine Anzahl von federnden Rollen, die das Glasrohr gegen das Walzenpaar drücken und geraderichten. An den zu trennenden Stellen sind Brenner mit scharfen Stichflammen, und zwar am besten Knallgasflammen vorteilhaft aus Brennerdüsen von kapillarer Weite, angebracht, die das Glasrohr tangential treffen und bei der Drehung auf einer ringförmigen Linie erhitzen. Die jeweils von der Flamme getroffene Stelle kommt unmittelbar darauf mit den kalten Metallwalzen in Berührung, so daß ein glatter Sprung erzeugt wird.The device according to the invention consists of two parallel smooth 'Metal rollers, which also exist in several alternating pairs can be that form a channel for receiving the glass tube to be cut and which, rotating in the same sense, set the glass tube in rotation. To not either To be able to process straight glass tubes, there is one above the rollers Number of resilient rollers that press the glass tube against the pair of rollers and straighten it. There are burners with sharp flames at the points to be cut, namely at the best oxyhydrogen flames advantageously from burner nozzles of capillary width, attached, which meet the glass tube tangentially and when rotating on an annular line heat. The point hit by the flame comes immediately afterwards in contact with the cold metal rollers so that a smooth crack is produced.
