Description

Rotierende Scheren- mit- großen. Messerkreisen haben den Vorteil, daß das Messerpaar erst nach zwei oder mehr Umdrehungen der Messerträger zum Schnitt gebracht werden kann; sie bieten deshalb die Möglichkeit, die. Messer-" geschwindigkeit erheblich zu steigern, d. h. auch bei hohen Walzgutgeschwindigkeiten noch einwandfreie Schnitte zu erzielen.Rotating scissors - with - large. Knife circles have the advantage that the pair of knives only after two or more revolutions of the knife carrier to cut can be brought; they therefore offer the possibility of. Knife "speed to increase significantly, d. H. still flawless even at high rolling stock speeds To achieve cuts.

Der praktische Betrieb derartiger Scheren bringt Schwierigkeiten mit sich, weil die Messer nacheinander auch dann die Bewegungsbahn des Walzgutes durchlaufen, wenn sie nicht zum Schnitt kommen; dabei sind Beschädigungen der Walzader oder der Messer besonders infolge der hohen Geschwindigkeiten unvermeidlich.The practical operation of such scissors presents difficulties because the knives also follow the path of the rolling stock one after the other, if they don't get to the cut; this includes damage to the rolling vein or the Knives inevitable, especially due to the high speeds.

Erfindungsgemäß soll diesen Schwierigkeiten' durch eine in Abhängigkeit von den Messerträgern gesteuerte, in vertikaler Ebene schwenkbare Führung begegnet werden, die das Walzgut im Augenblick des Messerdurchlaufes durch die Bahn der Walzader anhebt und so aus dem Bereich- des Messers herausbringt. Diese Führung kann entweder mit entsprechender Abstimmung auf die .Umläufe des anderen Messers von einem Messerträger gesteuert werden oder von beiden gemeinsam-:- Es werden dabei sowohl Steuerungen mechanischer als auch elektrischer Art als in den Rahmen der Erfindung fallend angesehen.. Das in ,der -Zeichnung schematisch dargestellte Ausführungsbeispiel des Erfindungsgedankens stellt eine- Steuerung mechanischer Art dar, die voneinem Messerträger beeinflußt wird. Auf der Welle i des Messerträgers z ist.. eine Exzenterstange 3 angeordnet, die bei 4 an die Führung 5 angelenkt die Ader 6 taktmäßig nach oben bzw. nach unten aus dem Bereich der Messer 7 und 7' herausbringt.According to the invention these difficulties' by a dependent encountered a guide controlled by the knife carriers and pivotable in a vertical plane that the rolling stock at the moment the knife passes through the path of the rolling wire lifts and thus brings it out of the area of the knife. This guided tour can either with appropriate coordination with the .Umaps of the other knife from a knife carrier be controlled or by both together -: - There are both controls mechanical as well as electrical kind as falling within the scope of the invention .. The embodiment of the inventive concept shown schematically in the drawing represents a control of a mechanical type, which is influenced by a knife carrier will. An eccentric rod 3 is arranged on the shaft i of the knife carrier z, hinged at 4 to the guide 5, the core 6 clockwise upwards or downwards brings out of the area of the knives 7 and 7 '.
