Description
Es ist bekannt, Ampullen, Glühlampen oder ähnliche Gegenstände aus Glas durch Aufblasen eines erhitzten Rohrteiles herzustellen, wobei das Ausgangsrohr entsprechend dem kleinsten Durchmesser des Gegenstandes gewählt wurde. Wenn aus einem engen Rohr ein verhältnismäßig weiter Körper aufgeblasen werden soll, so muß das enge Rohr sehr starkwandig sein, damit der weite Teil noch genügend Wandstärke besitzt. Hieraus ergeben sich große Schwierigkeiten, denn wenn das Ausgangsrohr zu starkwandig ist, sind die nachfolgenden Arbeitsvorgänge, wie Zuschmelzen von Ampullen oder Einschmelzen der Tellerröhren in Glühlampen, überhaupt nicht oder nur sehr schwer durchführbar.It is known to make ampoules, light bulbs or similar items Manufacture glass by inflating a heated pipe part, the starting pipe was chosen according to the smallest diameter of the object. When out a relatively wide body is to be inflated in a narrow tube, so must the narrow pipe must be very thick-walled so that the large part still has sufficient wall thickness owns. This creates great difficulties because when the exit pipe is too thick-walled, the subsequent operations, such as melting Ampoules or melting the plate tubes in incandescent lamps, not at all or very difficult to implement.
Man mußte deshalb bisher auf die Herstellung einer Menge von Gegenständen-verzichten, die durch Aufblasen aus Glasröhren erzeugt werden sollten. Durch die Erfindung werden die zuerst angeführten Nachteile beseitigt, und darüber hinaus wird die Möglichkeit gegeben, eine ganze Anzahl von Gegenständen herzustellen, die bisher nicht hergestellt «-erden konnten.So up to now one had to forego the production of a multitude of objects, which should be produced by inflation from glass tubes. Through the invention the disadvantages listed first are eliminated, and furthermore the possibility given to manufacture a number of items that were not previously manufactured «- could earth.
Das Verfahren nach der Erfindung besteht darin, daß Ampullen, Glühlampen od. ä. Gegenstände aus Glasröhren hergestellt werden, deren Durchmesser etwa in der Mitte zwischen dem größten und dem kleinsten Durchmesser des Fertigerzeugnisses liegt, deren Wandstärke in Abhängigkeit von der gewünschten Wandstärke des Fertigerzeugnisses bemessen wird, wobei das Erweitern - wie an sich bekannt - durch Aufblasen und das Verengen -wie ebenfall,-an- sich bekannt -. mittels Werkzeuge erfolgt.The method according to the invention consists in that ampoules, incandescent lamps od. Ä. Objects are made from glass tubes, the diameter of which is approximately in the middle between the largest and smallest diameter of the finished product whose wall thickness depends on the desired wall thickness of the finished product is measured, whereby the expansion - as known per se - by inflation and the Narrow -as also, -an known -. by means of tools.
Dadurch wird es möglich, ohne die Verwendung übermäßig großer Wandstärken im engen Teil doch eine genügende Wandstärke im weiten Teil zu erzielen.This makes it possible without the use of excessively large wall thicknesses to achieve a sufficient wall thickness in the large part in the narrow part.
Bei der Herstellung von Glühlampen wird am verengten Halsteil erfindungsgemäß ein Innen- oder Außengewinde angeformt, wodurch eine vorteilhafte Befestigung des Sockels gegeben ist.In the manufacture of incandescent lamps, the invention is carried out on the narrowed neck part an internal or external thread formed, whereby an advantageous attachment of the Base is given.
Die Erfindung ist aus der Zeichnung ersichtlich. In Abb. i und 2 wird aus dem Rohr mittleren Durchmessers der weite Teil aufgeblasen und in Abb. 3 der enge Teil durch Werkzeuge zusammengedrückt.The invention can be seen from the drawing. In Fig. I and 2 is from the tube of medium diameter the large part is inflated and in Fig. 3 the tight part compressed by tools.
Dabei ist es gleichgültig, welcher der beiden Arbeitsvorgänge zuerst ausgeführt wird. In Abb. .1, 4a und 4b ist die fortlaufende Arbeitsmöglichkeit dargelegt, indem der aufgeblasene Körper von dem Vorratsrohr abgetrennt wird, ähnlich wie es bei der Erzeugung von Ampullen geschieht.It does not matter which of the two work processes comes first is performed. In Fig. 1, 4a and 4b the continuous working possibility is shown, by severing the inflated body from the supply tube, similar to that happens in the production of ampoules.
Dabei kann das Verengen vor dem Abtrennen erfolgen, oder aber der Körper wird auf einer besonderen Maschine verengt.The narrowing can take place before the separation, or the Body is narrowed on a special machine.
In Abb. 5 wird die Anformung eines Innen- oder Außengewindes gezeigt.In Fig. 5 the molding of an internal or external thread is shown.
