Abstract

Bei einem Antrieb für einen in einem Stößel (6) einer mechanischen formpresse verschieblich gelagerten, patrizenseitigen Auswerfer mit einem in dem Stößel (6) schwenkbar gelagerten Winkelhebel (15), des­ sen einer Schenkel (14) auf das von der Patrize abgewandte Ende des Auswerfers wirkt und dessen anderer Schenkel in Antriebsverbindung mit einem Lenker (17) steht, der an einem Antriebspleuel (5) für den Stößel (6) angelenkt ist und auf den Winkelhebel (15) taktweise An­ triebsbewegungen überträgt, besteht die Aufgabe, in der Antriebsver­ bindung linienförmige Berührungen zu vermeiden und eine Anpassung an unterschiedliche Höhen von Matrize und Patrize zu ermöglichen. Die Lösung besteht darin, die Antriebsverbindung möglichst weitgehend als Gelenkkette auszubilden, wobei der an dem Antriebspleuel angelenkte Lenker (17) annähernd rechtwinkelig zu der Bewegungsrichtung des Stös­ sels (6) liegt und der daran angelenkte eines zweiarmigen Hebels (19) sich annähernd parallel zu der Bewegungsrichtung des Stößels (6) erstreckt. In a drive for one in a plunger (6) of a mechanical molding press with movably mounted, ejector on the patrix side one in the plunger (6) pivotally mounted angle lever (15), the sen a leg (14) on the end facing away from the male Ejector acts and its other leg in drive connection with a handlebar (17) on a connecting rod (5) for the Tappet (6) is articulated and on to the angle lever (15) at intervals transmits drive movements, the task is in the Antriebsver Avoid binding linear touches and adapt to allow different heights of die and patrix. The The solution is to use the drive connection as much as possible Form link chain, the articulated on the drive rod Handlebar (17) approximately at right angles to the direction of movement of the push sels (6) and that of a two-armed lever (19) approximately parallel to the direction of movement of the plunger (6) extends.
