Description
Vorrichtung zum Härten von Glasgegenständen Die Erfindung bezieht sich auf solche Vorrichtungen zum Härten von Glasgegenständen, bei welchen ein gasförmiges Kühlmittel, wie Luft, Gas oder Dampf, durch Austrittsöffrinngen von Rohren, Hohlplatten 'o. dgl. auf den vorher erhitzten Glasgegenstand zwecks plötzlicher Abkühlung desselben. geblasen wird.. Um. eine in allen Teilen des Glases gleichmäßige Spannung zu erzeugen, werden die Blasöffnungen, welche die-,Form von_ Löcbern;, -. Schlitzen, konischen Düsen haben, in <regelmäßiger Verteilung zum Glasgegenstand- an= geordnet. Zur Erhöhung der Gleichmäßigkeit der Abkühlung werden die._Blasöffnungen bzwr , die mit ihnen versehenen Rohrrähmen während des Kühlens auch vielfach m eine kreisende oder ähnliche Bewegung versetzt. Man kann aber ,auch die Kühlvorrichtungen stillstehen lassen und den zu härtenden Glasgegenstand bewegen.Apparatus for tempering glass objects The invention relates to refer to such devices for hardening glass objects in which a gaseous Coolants, such as air, gas or steam, through outlet channels in pipes, hollow plates 'O. Like. On the previously heated glass object for the purpose of sudden cooling of the same. is blown .. Um. to create an even tension in all parts of the glass, become the blow holes, which the-, Form von_ Löcbern ;, -. Slots, conical Nozzles are arranged in <regular distribution to the glass object. To the Increasing the uniformity of the cooling will die._Blassöffnungen or die with them provided pipe frames during cooling also often m a circular or similar movement. But you can also stop the cooling devices and move the glass object to be hardened.
Mit diesen Mitteln wurden bereits sehr gute Erfolge erzielt. Unter schwierigen . Verhältnissen, besonders bei dünnen Gläsern, genügen aber die bekannten Maßnahmen. nicht, um eine ausreichende Härtung zu erzielen.Very good results have already been achieved with these funds. Under difficult. However, the well-known conditions are sufficient, especially for thin glasses Measures. not to achieve sufficient hardening.
Versuche haben nun ergeben, daß. durch Erhöhung der Austrittsgeschwindigkeit des Kühlmittels die Abkühlung wesentlich wirksamer gestaltet und die Härtung- entsprechend vervollkommnet werden kann. Zur Erzielung einer hohen, Austrittsgeschwindigkeit wird erfindungsgemäß vorgeschlagen, die Austritts-' öffnungen für das Kühlmittel in Form von Entspannungsdüsen ,auszubilden. Dabei kann die Ausbildung derart sein, daß die Düsen dem Kühlmittel bei einem bestimmten Druck eine Strömungsgeschwindigkeit .erteilen, die über die Schallgeschwindigkeit hinausgeht.Tests have now shown that. by increasing the exit speed of the coolant makes the cooling much more effective and the hardening accordingly can be perfected. To achieve a high exit speed is proposed according to the invention, the outlet 'openings for the coolant in the form of expansion nozzles. The training can be that the nozzles give the coolant a flow velocity at a certain pressure .share that goes beyond the speed of sound.
In der Zeichnung ist als beispielsweise Ausführungsform des Erfindungsgegenstandes ein Blasrohr i, mit Austrittsöffnungen 2 in Form Lävalscher Düsen m einem Schnitt dargestellt.In the drawing is an example of an embodiment of the subject matter of the invention a blowpipe i, with outlet openings 2 in the form of Läval nozzles m one section shown.
