Description

Verfahren zur Herstellung von @reßteilen, insbesondere Knöpfen aus- Glas Die Herstellung von Glasknöpfen erfolgt üblicherweise aus Glasstangen. Bei der Verarbeitung dieser Stangen ist es jedoch bis jetzt noch nicht möglich gewesen, einkontinuierlichesArbeitsverfahren zu verwirklichen. Das erfindungsgemäß vorgeschlagene kontinuierliche Verfahren 'kann halb- oder ganzautomatisch ausgebildet werden und gestattet, unter jeweiliger Ausnutzung der dem Glasstab zugeführten Hitze, laufend und rasch den erhitzten Glasstab zu verarbeiten.Process for the production of cut parts, in particular buttons Glass Glass buttons are usually made from glass rods. at however, it has not yet been possible to process these rods to realize a continuous working process. The proposed according to the invention continuous process' can be trained semi-automatically or fully automatically and permitted, using the heat supplied to the glass rod, continuously and quickly process the heated glass rod.

Erfindungsgemäß wird vorgeschlagen, den zur Verarbeitung gelangenden Stab aus in der Hitze plastisch werdendem Material, insbesondere aus Glas, durch einen senkrecht angeordneten Erhitzungsofen, senkrecht von oben nach unten hindurchzuführen. Hierbei wird der Glasstab an seiner unteren Spitze einer besonders konzentrierten Hitzeeinwirkung ausgesetzt und nach oben hin allmählich vorgewärmt. Direkt unterhalb dieses Erhitzungsofens, der auch evtl. nur aus ein oder mehreren zweckmäßig ausgebildeten offenen Flammen, einem elektrischen Strahlungserhitzungsofen o. dgl., bestehen kann, wird eine Preß- und Formvorrichtung angeordnet, die von der auf die erforderliche Verformungstemperatur gebrachten Spitze des Stabes das für das Preßstück, z. B. Glasknopf, erforderliche Stück abschneidet und es zum fertigen Knopf ausprägt. Es ist zweckmäßig, hierbei dem Glasstab eine im Rhythmus des jeweiligen Prägevorgangs vor sich gehende, senkrechte Auf- und Abwärtsbewegung zu erteilen. Hierbei wird der Glasstab jeweils nach Abschneiden der Spitze in die erhitzte Zone zurückgezogen und dann wieder zum Abschneiden des nächsten Preßlings nach unten vorgeschoben. Bei entsprechend geschickter Ausbildung der Erhitzungsvorrichtung kann jedoch auch unter Umständen auf das jeweilige Zurückziehen des Glasstabes verzichtet werden.According to the invention, it is proposed to use the Rod made of material that becomes plastic in the heat, in particular made of glass a vertically arranged heating furnace through vertically from top to bottom. Here the glass rod becomes particularly concentrated at its lower tip Exposed to heat and gradually preheated towards the top. Right below this heating furnace, which may only consist of one or more appropriately designed open flames, an electric radiant heating furnace or the like, can exist, a pressing and forming device is arranged, which is from the to the required Deformation temperature brought tip of the rod for the pressed piece, z. B. Glass button, cut off the required piece and emboss it into the finished button. It It is advisable to place one on the glass rod in the rhythm of the respective embossing process to issue vertical up and down movement in progress. Here is the glass rod is withdrawn into the heated zone after the tip has been cut off and then advanced down again to cut off the next compact. With appropriately skilled training of the heating device can however, under certain circumstances, the respective withdrawal of the glass rod is dispensed with will.

Da für die gleichmäßige Ausbildung der Preßlinge das Abschneiden einer immer gleichen Werk= Stoffmenge erforderlich ist und die Werkstoffmenge von der Dicke des Stabes abhängig ist, kann an der Vorschubvorrichtung eine Verstellvorrichtung angebracht werden, die den Durchmesser des Stabes abtastet und die Größe des schrittweisen Vorschubs bei größerem Durchmesser verkleinert bzw. bei kleinerem Durchmesser vergrößert.As for the uniform formation of the compacts the cutting off a always the same work = amount of material is required and the amount of material of the Depending on the thickness of the rod, an adjustment device can be installed on the feed device attached, which senses the diameter of the rod and the size of the incremental Feed reduced with larger diameter or increased with smaller diameter.

Die Wärmevorrichtung für den senkrecht angeordneten Stab wird im allgemeinen mit Gasflammen ausgestattet sein, doch kann auch eine Erwärmung durch elektrische Erhitzung erfolgen.The heating device for the vertically arranged rod is generally be equipped with gas flames, but can also be heated by electrical Heating take place.
