Description

DEUTSCHESGERMAN

Zum Wenden von Werkstücken beim Schmieden bedient man sic'h in Anpassung an die hohe Arbeitsgeschwindigkeit neuzeitlicher Schmiedepressen im allgemeinen folgender Maßnahmen:For turning workpieces during forging, they are generally used in adaptation to the high working speed of modern forging presses the following measures:

Das Schmiedestück wird entweder in zwei an Schmiedekranen hängende Wendeketten eingelegt, von denen die eine motorisch angetrieben wird, oder in die Zange eines Schmiede-Manipulators genommen und entsprechend den Erfordernissen des Schmiedevorganges gehand'habt. Es ist auch bekannt, beide Enden des Schmiedestückes durch je einen Manipulator zu erfassen und das Werkstück zwischen den Zangen durch deren Drehantrieb zu wenden.The forging is either placed in two turning chains hanging from forged cranes, one of which is driven by a motor, or taken into the tongs of a forge manipulator and handled according to the requirements of the forging process. It is also known to both To grasp the ends of the forging by a manipulator each and the workpiece between the To turn the pliers through their rotary drive.

Manipulatoren haben bei kleineren Stücken bis etwa 10 t Gewicht den Vorteil großer Wendigkeit in bezug auf die Handhabung des Schmiedestückes. Sie werden aber bei größeren Schmiedestücken, welche die 50-t-Grenze überschreiten, schwer und besitzen bei der Längsbewegung des Schmiedestückes eine erhebliche Massenträgheit, so daß der Vorteil der größeren Beweglichkeit l>eim Wenden durch das trägere Arbeiten beim Verschieben in der Längsrichtung wieder verlorengeht. Das Schmiedestück in zwei Wendeketten einzulegen und dabei nur eine Wendekette anzutreiben, reicht wegen der erreichbaren geringen Arbeitsgeschwindigkeit nicht mehr aus.Manipulators have the advantage of great maneuverability for smaller pieces up to about 10 t in weight regarding the handling of the forging. But with larger forgings, which the Exceeding 50 t limit, heavy and have a considerable length when the forging moves longitudinally Mass inertia, so that the advantage of greater mobility when turning through the more inert Work is lost again when moving in the longitudinal direction. The forging in two Inserting turning chains and driving only one turning chain is sufficient because of the low achievable Working speed is no longer sufficient.

Erfindungsgemäß kann nun die Arbeitsgeschwindigkeit dadurch wesentlich gesteigert werden, daß beide Wendeflaschen angetrieben und gemeinsam gesteuert werden.According to the invention, the working speed can now be increased significantly that both Reversible bottles are driven and controlled together.

Die AVendeketten können dabei in bekannter Weise durch schaltbare Kupplungen wahlweise an einen durchlaufenden Antriebsmotor angekuppelt oder von diesem abgekuppelt werden.The AV end chains can optionally be connected to one in a known manner by switchable couplings be coupled or uncoupled from the drive motor running through it.

Statt des An- und Abkuppeins können die Wendeketten auch in ebenfalls bekannter Weise mit ihren Antriebsmotoren durch Rutschkupplungen verbunden werden. Weil das zum Wenden erforderliche Drehmoment auf zwei Wendeantriebe aufgeteilt ist, braucht die Rutschkupplung nicht auf ein so großes Moment eingestellt zu werden, als wenn nur eine Verfahren zum Wenden
schwerer Werkstücke beim SchmiedenInstead of coupling and uncoupling, the turning chains can also be connected to their drive motors in a known manner by slip clutches. Because the torque required for turning is divided between two turning drives, the slip clutch does not need to be set to such a large torque as if only one method for turning
