KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Speiseapparate für Pilgerwalzwerke, deren Dornspindel, auf welcher das Walzgut sitzt, immer ruckweise um 900 weiter gedreht werden muß. Diese Drehung findet zumeist in ein und derselben Richtung ruckweise um 90 ° statt, zu welchem Zweck durch eine mechanische Drehvorrichtung eine Feder, welche auf der Dornspindel sitzt, gespannt wird. Nach Loslassen des Walzgutes von Seiten der Arbeitswalzen entspannt sich dann diese Feder wieder upd schleudert so das Walzgut um 90 ° vor und so fort.The invention relates to apparatus for feeding rocker mills whose stem Spindle on which the rolling stock is located, must always be jerks further rotated by 90 0th This rotation usually takes place in one and the same direction jerkily by 90 °, for which purpose a spring, which sits on the mandrel spindle, is tensioned by a mechanical rotating device. After the rolling stock has been released from the work rolls, this spring then relaxes again and so throws the rolling stock forward by 90 ° and so on.
Gemäß der Erfindung wird die ruckweise Drehung in ein und derselben Richtung überflüssig, und das Walzgut wird nur um einen bestimmten, für das Rundwalzen des Walzgutes erforderlichen Winkel hin und zurück gedreht. Das Walzgut wird dadurch für jeden Arbeitshub der Arbeitswalzen immer wieder auf die hohe Kante gestellt. Die Art dieses Antriebes ermöglicht die genaue Begrenzung des Schwingungswinkels des Walzgutes. According to the invention, the jerky rotation in one and the same direction is superfluous, and the rolling stock is only back and forth through a certain angle required for the rolling of the rolling stock turned. As a result, the rolling stock is always put on the high edge for each working stroke of the work rolls. The kind this drive enables the precise limitation of the oscillation angle of the rolling stock.
Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Drehvorrichtung dargestellt. Die Dornspindel α soll um einen bestimmten Winkel hin und zurück gedreht werden.In the drawing, an embodiment of the new rotating device is shown. The mandrel spindle α should be rotated back and forth through a certain angle.
Dieser Zweck wird erreicht durch den zweiseitig wirkenden Zylinder b, der zwangläufig von den Arbeitswalzen so gesteuert wird, daß der darin befindliche Kolben seine Hubbewegungen beginnt, sobald das Walzgut von den. Arbeitswalzen losgelassen wird. Als Antriebsmittel sind Dämpfe oder gespannte Luft oder gespannte Gase vorgesehen. Ferner wird dieser Zweck erreicht durch einen Elektromagneten, der ebenfalls von den Arbeitswalzen oder deren Antrieb gesteuert wird. Der Hub des Kolbens und des Elektromagneten oder auch der Drehwinkel des letzteren, wenn er wie in der Zeichnung als Skizze s ausgebildet wird, wird so gewählt, daß der für das Rundwalzen erforderliche Schwingungswinkel erreicht wird. This purpose is achieved by the double acting cylinder b, which is inevitably controlled by the work rolls so that the piston located therein begins its stroke movements as soon as the rolling stock of the. Work rolls is released. Vapors or compressed air or compressed gases are provided as drive means. This purpose is also achieved by an electromagnet, which is also controlled by the work rolls or their drive. The stroke of the piston and the electromagnet or the angle of rotation of the latter, if it is designed as a sketch as in the drawing, is chosen so that the oscillation angle required for round rolling is achieved.
