Description

Walzeinrichtung zum Herstellen von Kugeln aus vorgeballten, warmen Stangenabschnitten mittels verschiedenen Durchmesser aufweisender Rillenwalzen Die Erfindung bezieht sich auf eine Walzeinrichtung zur Herstellung von Kugeln aus vorgebauten warmen Stangenabschnitten mittels verschiedenen Durchmesser aufweisender Rillenwalzen.Rolling device for the production of balls from pre-balled, warm Rod sections by means of grooved rollers having different diameters The invention relates to a rolling device for producing balls from prebuilt warm rod sections by means of grooved rollers of different diameters.

Es ist bekannt, durch zwei in gleicher Richtung sich drehende Walzen, die mit Rippen versehen sind, einen zwischen sie eingebrachten Stab bei Verschiebung einer Walze gegen die andere in einzelne Stücke zu zerteilen und diese Stücke, die durch eine besondere Einrichtung beliebig lange zwischen den Walzen. gehalten werden können, zu Kugeln auszuwalzen. Hierbei ist jedoch eine Zapfenbildung an den Werkstücken nicht zu vermeiden, weil diese stets in einer Ebene sich bewegen.It is known, by two rollers rotating in the same direction, which are provided with ribs, a rod inserted between them when displaced one roller against the other to cut into individual pieces and these pieces that thanks to a special device, for any length of time between the rollers. being held can roll out into balls. In this case, however, there is a peg formation on the workpieces unavoidable because they always move in one plane.

Es ist weiter bekannt, vorgeballte Werkstücke der Einwirkung zweier in gleicher Richtung sich drehenden Walzen auszusetzen, die verschiedene Umfangsgeschwindigkeiten haben und deren Rillen einen solchen Verlauf haben, daß die Werkstücke in Achsrichtung der Walzen wandern, so daß eine Kugelform erzielt werden kann. Bei dieser Walzeinrichtung kann man jedoch die Ausgestaltung der Walzen im voraus nicht mit solcher Sicherheit bestimmen, daß eine einwandfreie Kugelform sich ergibt, weil die Werkstücke aus den Walzen herausfallen, sobald sie die waagerechte Walzmittelebene, wo die endgültige Formgebung stattfindet, erreicht haben.It is also known that preballed workpieces are exposed to the action of two exposing rollers rotating in the same direction at different peripheral speeds have and the grooves have such a course that the workpieces in the axial direction of the rollers move so that a spherical shape can be achieved. With this rolling device however, one cannot design the rolls in advance with such certainty determine that a perfect spherical shape results because the workpieces from the rollers fall out as soon as they reach the horizontal center plane where the final Shaping takes place, have achieved.

Zur Vermeidung dieser Nachteile sind gemäß der Erfindung drei Walzen mit senkrecht zur Achse verlaufenden Rillen vorgesehen, von denen die eine; 3, zwischen den beiden anderen, z, 2, unterhalb der Walzebene liegt, eine Aussparung zur Aufnahme der fertigen Kugel hat und mit solcher Geschwindigkeit angetrieben wird, daß ein zu frühes Heraustreten der jeweilig dem Walzvorgang unterworfenen Kugel aus dem Kaliber verhindert wird, und eine der beiden anderen Walzen in bekannter Weise etwas geneigt zur senkrechten Walzmittelebene angeordnet ist, damit die zu walzende Kugel zur Vermeidung einer Zapfenbildung nicht stets in einer Ebene umläuft.To avoid these disadvantages, there are three rollers according to the invention provided with grooves perpendicular to the axis, one of which; 3, between the other two, z, 2, is below the rolling plane, a recess for receiving of the finished ball and is driven at such a speed that a too early emergence of the respective ball subjected to the rolling process from the Caliber is prevented, and one of the other two rollers in a known manner something is arranged inclined to the vertical rolling center plane, so that the ball to be rolled does not always revolve in one plane to avoid pin formation.

Aus der Zeichnung ist die Anordnung der Walzen erkennbar. Die geneigte Lage der Walze z ist aus dem Grundriß ersichtlich.The arrangement of the rollers can be seen from the drawing. The inclined The position of the roller z can be seen from the plan.
