Abstract

The spheres are produced by inducing sphere formation of the molten starting material by its exposure to the forces exerted by a molten medium having high surface tension, pref. molten glass. Snipped lengths of metal wire are dropped into the molten glass, where they melt and form perfect spheres.

Description

Kugelherstellung Die Erfindung betrifft ein Verfahren zur Herstellung von Stahl-oder Metallkugeln0 Stahlkugeln werden für Kugellager benutzte Die bisherigen Verfahren beschränzen sich auf eine Gestaltung des Ausgangswerkstoffes in Formens wobei keine ideale Kugelgestalt des Schleifrohlinges erreicht wird0 Die Folgen sind vermehrte Nacharbeit und erhöhter Werkstoff- und Zeitverlust.Ball production The invention relates to a method for production of steel or metal balls0 Steel balls are used for ball bearings The previous ones Processes are limited to shaping the starting material in the form of molding whereby no ideal spherical shape of the grinding blank is achieved0 The consequences are increased rework and increased material and time loss.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung von Stahl-und Metallkugeln zu vereinfachen0 Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß vorbestimmte Mengen des Ausgangswerkstoffes einer Glasschmelze zugeführt werden und durch die hohe Oberflåchenspannung des flüssigen Glases die Gestalt einer idealen Kugel annehmen.The invention is based on the task of producing steel and To simplify metal balls 0 This object is achieved according to the invention by that predetermined amounts of the starting material are fed to a glass melt and due to the high surface tension of the liquid glass, the shape of an ideal one Accept ball.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß sich die Nacharbeit der erzeugten Kugeln auf ein luinimum beschränkt und ein chleifen der Kugeln nicht erforderlich isto In der Zeichnung ist eine mögliche Ausführung der Vorrichtung dargestellt, Der z,B. als Draht 1 zugeführte Ausgangswerkstoff wird durch eine Schere 2 in vorbestimmten Mengen abgetrennt und fällt in einen Behälter 3 mit flüssigem Glas 4 Die führung des Glasgranulates zur Ergänzung des Behälterinhaltes und die Beheizung erfolgen in geeigneter Weise, Durch die hohe Temperatur des flüssigen Glases 4 wird der eingeführte metallische Ausgangswerkstoff 1 flüssig und nimmt Kugelgestalt an. Damit sinkt er zur Auslaßöffnung 5 und verfestigt sich durch die zum Auslaß 5 des Behälters 3 fallende temperatur des flüssigen Glases 4 Der Glasstrang 6 mit de eingeschlossenen Kugeln wird fortlaufend einem Wasserbehälter 7 zugeführt und das Granulat mit den Kugeln aus der Offnung 8 ausgetragen0 Die Trennung von Granulat und Stahl- oder Metallkugeln erfolgt durch bekannte Maßnahmen.The advantages achieved by the invention are that the reworking of the balls produced is limited to a minimum and grinding of the balls is not required o The drawing shows a possible version the device shown, The z, B. as wire 1 supplied starting material separated by scissors 2 in predetermined amounts and falls into a container 3 with liquid glass 4 The guide of the glass granulate to supplement the contents of the container and the heating is done in a suitable manner, due to the high temperature of the liquid Glass 4, the introduced metallic starting material 1 becomes liquid and takes Spherical shape. So that it sinks to the outlet opening 5 and solidifies through the to the outlet 5 of the container 3 falling temperature of the liquid glass 4 the glass strand 6 with the enclosed balls is continuously fed to a water container 7 and the granulate with the balls discharged from the opening 80 The separation of Granules and steel or metal balls are made using known measures.
