Abstract

The invention relates to a pair of double trimming shears, with a fixed lower blade and an upper blade which is driven in such a way that it can be raised and lowered by means of eccentric shafts together with connecting rods, wherein each connecting rod is arranged on an eccentric shaft of its own and, on account of different crank radii, their offset and different connecting rod lengths, the upper blade performs a rolling cutting motion, which is guided by a sliding block; the length of the connecting rods is variable.

Description

Doppelbesäυmschere Doppelbesäυmschere

Die Erfindung betrifft eine Doppelbesäumschere, mit einem ortsfesten Untermesser und einem durch Exzenterwellen über Pleuelstangen heb- und senkbar angetriebenen Obermesser, wobei jede Pleuelstange auf einer eigenen Exzenterwelle angeordnet ist und das Obermesser aufgrund unterschiedlicher Kurbelradien, deren Versatz und unterschiedlicher Pleuelstangenlängen eine Rollschnittbewegung ausführt, die durch einen Kulissenstein geführt wird.The invention relates to a Doppelbäumschere, with a stationary lower blade and a raised by eccentric shafts over connecting rods and lowerable driven upper blade, each connecting rod is arranged on a separate eccentric shaft and the upper blade due to different crank radii whose offset and different connecting rod lengths executes a rolling cut movement by a sliding block is led.

Blech- oder Besäumscheren dieser Art sind beispielsweise aus der DE 23 29 096 A1 oder der DE 25 10 881 A1 bekannt.Sheet metal or Besäumscheren this type are known for example from DE 23 29 096 A1 or DE 25 10 881 A1.

Die zurzeit eingesetzten Doppelbesäumscheren, die über Kurbelwellen angetrieben werden, sind nicht variabel im Bezug auf die Schnittbewegung.The currently used double trimming shears, which are driven by crankshafts, are not variable with respect to the cutting movement.

Der Obermesserschlitten, der mittels starren Pleuels mit den Exzenterwellen gekoppelt ist, lässt keinerlei Veränderung der Anlenkpunkte zu.The upper knife carriage, which is coupled by means of rigid connecting rod with the eccentric shafts, allows no change in the articulation points.

Das Bogenmesser vollzieht eine Rollschnittbewegung, die sich aus den unterschiedlichen Kurbelradien, deren Versatz und den unterschiedlichen Pleuellängen zusammensetzt. Geführt wird das Messer in Schnittrichtung mittels drehbar gelagerten Kulissenstein.The bow knife performs a rolling cut movement, which is composed of the different crank radii, their offset and the different conrod lengths. The knife is guided in the cutting direction by means of rotatably mounted sliding block.

Bei der jetzigen Konstruktion lässt sich die Schnittdicke nicht beliebig vergrößern.In the current construction, the section thickness can not be increased arbitrarily.

Ebenso ist es nicht möglich die Schnittgeometrie zu ändernIt is also not possible to change the cut geometry

Hieraus ergibt sich, dass die Schnittbewegung des Obermessers immer gleich ist, so dass beispielsweise die Blechdicke des zu teilenden Bleches ohne jeglichen Einfluss auf den Schneidvorgang ist, aber auch nicht berücksichtigt werden kann. Damit wird die Schnittdicke, die die Maschine zulässt auch begrenzt.It follows that the cutting movement of the upper blade is always the same, so that, for example, the sheet thickness of the sheet to be divided without any influence on the Cutting process is, but also can not be considered. This also limits the cutting thickness that the machine allows.

Andererseits ist auch der Materialvorschub durch die größte Blechdicke bestimmt, so dass bei dünnen Blechen nur ein geringerer Durchsatz möglich ist.On the other hand, the material feed is determined by the largest sheet thickness, so that with thin sheets only a lower throughput is possible.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Doppelbesäumschere zu schaffen, deren Schnittbewegung veränderbar ist, so dass eine Anpassung an unterschiedliche Schnittdicken, größere Blechdicken und ein veränderbarer Materialdurchsatz möglich sind.The invention is therefore an object of the invention to provide a Doppelbäumschere whose cutting movement is variable, so that an adaptation to different cutting thicknesses, larger sheet thicknesses and a variable material throughput are possible.

Gelöst wird diese Aufgabe erfindungsgemäß bei einer Doppelbesäumschere, mit einem ortsfesten Untermesser und einem durch Exzenterwellen über Pleuelstangen heb- und senkbar angetriebenen Obermesser, wobei jede Pleuelstange auf einer eigenen Exzenterwelle angeordnet ist und das Obermesser aufgrund unterschiedlicher Kurbelradien, deren Versatz und unterschiedlicher Pleuelstangenlängen eine Rollschnittbewegung ausführt, die durch einen Kulissenstein geführt wird dadurch, dass die Länge der Pleuelstangen veränderbar ist.This object is achieved according to the invention in a double trimming, with a stationary lower blade and a raised by eccentric shafts over connecting rods and lowerable driven upper blade, each connecting rod is arranged on a separate eccentric shaft and the upper blade performs due to different crank radii whose offset and different connecting rod lengths a rolling cut movement , which is guided by a sliding block in that the length of the connecting rods is changeable.

Dies kann auf verschiedene Weise erfolgen.This can be done in different ways.

So ist es möglich, dass jede Pleuelstange durch eine Mutter/Spindel-Verbindung unterteilt ist und die Veränderung der Länge der Pleuelstange durch relatives Verdrehen der Mutter gegenüber der Spindel erfolgt.Thus, it is possible that each connecting rod is divided by a nut / spindle connection and the change in the length of the connecting rod by relative rotation of the nut relative to the spindle.

Eine andere Möglichkeit ist, dass jede Pleuelstange durch eine Kolben/Zylinder-Verbindung unterteilt ist und die Veränderung der Länge der Pleuelstange durch relative Verschiebung des Kolbens zu dem Zylinder erfolgt.Another possibility is that each connecting rod is divided by a piston / cylinder connection and the change in the length of the connecting rod is effected by relative displacement of the piston to the cylinder.

Alternativ kann auch jede Pleuelstange durch eine Exzenterverbindung unterteilt sein und die Veränderung der Länge der Pleuelstange erfolgt durch relatives Verdrehen der Exzenterverbindung.Alternatively, each connecting rod can be subdivided by an eccentric connection and the change in the length of the connecting rod is effected by relative rotation of the eccentric connection.

Der Kerngedanke der Erfindung besteht somit darin, dass die Pleuellängen durch Einbau von Stellgliedern in ihrer effektiven Länge verändert werden können.The core idea of the invention thus consists in that the connecting rod lengths can be changed by incorporating actuators in their effective length.

Damit kann einerseits durch gleichmäßiges Verstellen die Höhe des Obermessers und somit die Eintauchtiefe verändert werden.Thus, on the one hand by uniform adjustment, the height of the upper blade and thus the immersion depth can be changed.

Andererseits kann auch durch ungleichmäßiges Verstellen die Obermesserbewegung und somit der Schnittverlauf und Schnittwinkel geändert werden. Diese Verstellung ermöglicht eine Anpassung auf unterschiedliche Blechdicken und Materialgüten. Es können auch größere Blechdicken mit dem Rollschnitt geschnitten werdenOn the other hand, by uneven adjustment, the upper blade movement and thus the cutting profile and cutting angle can be changed. This adjustment allows adaptation to different sheet thicknesses and material grades. It can also be cut larger sheet thicknesses with the roll cut

Im Sinne der gestellten Aufgabe ermöglicht die erfindungsgemäße Lösung somit ein Schneiden über einen größeren Dickenbereich. Damit ist auch eine Anpassung des Materialvorschubes möglich, und zwar dickenabhängig, so dass wiederum bei dünneren Blechen höhere Durchsätze erzielbar sind.In the sense of the stated object, the solution according to the invention thus enables cutting over a greater thickness range. Thus, an adaptation of the material feed is possible, namely thickness-dependent, so that in turn higher throughputs can be achieved with thinner sheets.
