Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung bezieht sich auf einThe present invention relates to a

Verfahren zum Pressen von Glasröhren mit Hilfe eines Stempels mit Wasserkühlung und einem am unteren Ende ausmündenden Preßluftkanal. Method of pressing glass tubes using a die with water cooling and a compressed air duct opening out at the lower end.

Die doppelwandige Form I wird, wie üblich, mit der zu einem Rohr erforderlichen Menge Glas gefüllt, dann wird der Stempel 2 hineingesenkt. Das neue Verfahren besteht nunThe double-walled form I is, as usual, with the amount required to make a pipe Glass filled, then the stamp 2 is lowered into it. The new procedure now exists

ίο zunächst darin, daß Preßluft zwischen Stempel und Glas gedrückt wird, wodurch die Luftschicht 3 gebildet wird, welche am Austrittsspalt 5 bei dem Kegel 4 am größten ist und sich dann in der ganzen Länge des Stempels zwischen- diesem und dem Glase hinzieht. .ίο first in the fact that compressed air between Stamp and glass is pressed, whereby the air layer 3 is formed, which on Exit gap 5 at the cone 4 is largest and then extends over the entire length of the The stamp is drawn between this and the glass. .

Auf diese. Weise ist während der nun folgenden Kühlung von innen heraus eine isolierende Luftschicht zwischen Stempel und Glasröhre und zugleich eine ganz gleichmäßige Stempelkühlung hergestellt.To this. Wisdom is one during the cooling that follows from within insulating layer of air between the stamp and the glass tube and at the same time a very even one Stamp cooling produced.

Sowie nämlich mit dem Einblasen von Preßluft durch den Kanal 6 begonnen ist, wird auch der Kühlwasserstrom in Gang gesetzt, und zwar in der Weise, daß das frische Wasser durch das Rohr 7 in die Ringkammer 8 eintritt. Hier wird es durch die Rohre 9 nach der Spitze des Stempels geleitet, streicht an den Wandungen desselben hoch und geht zu dem Abfluß 10 hinaus.As soon as compressed air has started to be blown through channel 6, the cooling water flow is also set in motion, in such a way that the fresh Water enters the annular chamber 8 through the pipe 7. Here it is through the Pipes 9 passed to the tip of the punch, strokes the walls of the same up and goes out to the drain 10.

Man hat Preßstempel sowohl mit Preßluftkanal als auch mit innerer Kühlung durch die Stempelspitze hineinreichende Zu-You have press rams with both compressed air duct and internal cooling the punch tip reaching into

führungsröhren verwendet. Der Preßstempel nach vorliegender Erfindung vereinigt einen Preßluftkanal mit einer besonderen, möglichst gleichmäßige Kühlung bewirkenden Anordnung der Kühlleitungen.guide tubes used. The ram according to the present invention combines one Compressed air duct with a special, as uniform as possible cooling effecting arrangement the cooling lines.
