Die Erfindung betrifft eine Abschneidevorrichtung für Strangpressen mit sowohl in Richtung des Stranges als auch quer zu ihm und parallel sich selbst nach einer Schablone zwangweise verschiebbarem Schneidrahmen. Bei diesen Abschneidevorrichtungen erfolgt die Bewegung des Schneidrahmens gemäß der Schablone durch einen zweiarmigen Hebel, von dessen Armen der eine am Schneidrahmen angreift, während der andere am Ende in der Schablone geführt ist. Die Drehung des Hebels erfolgt durch Rädergetriebe von der Schneidbügelwelle aus mittels senkrechter Welle, in deren Kopf der Hebel längsverschiebbar ist, um der Schablone folgen zu können. Bei dieser Art des Antriebes des den Schneidrahmen gemäß der Schablone bewegenden Hebels besteht, abgesehen von den Nachteilen, die das Rädergetriebe unterhalb der Strangbahnen nach sich zieht, der Übelstand, daß, infolge der Führung des Hebels in der Schablone an seinem freien Ende, ein Ecken und Klemmen der Führungsrolle in der Schablone eintritt, was den Gang erschwert und den Verschleiß der Schablone erhöht.The invention relates to a cutting device for extrusion with both in the direction of the strand as well as across it and inevitably parallel itself according to a template movable cutting frame. With these cutting devices the movement takes place of the cutting frame according to the template by a two-armed lever, from the arms of which one engages the cutting frame, while the other at the end in the Template is guided. The lever is rotated by means of a gear train from the Cutting frame shaft made by means of a vertical shaft, in the head of which the lever is longitudinally displaceable, to be able to follow the template. With this type of drive of the cutting frame according to the template moving lever consists, apart from the disadvantages, which the gear train below the strand tracks after the drawback that, as a result of the management of the lever in the template, attracts itself its free end, a corners and jamming of the guide roller occurs in the template, which makes the walk difficult and increases the wear and tear of the template.

Bei gewöhnlichen Dachziegelabschneidern ist es allerdings auch bekannt, durch den den Schneidbügel bewegenden Hebel auch die Bewegung des den Ziegel am anderen Ende abschneidenden Rahmens zu veranlassen. Hierbei sitzt aber der den Schneidbügel und den Schneidrahmen verbindende Hebel auf einem festen Drehzapfen am Rahmen. Eine Längsverschiebung des Verbindungshebels gemäß einer Schablone findet nicht statt. Es treten hier infolgedessen auch die Nachteile, welche durch den Erfindungsgegenstand beseitigt werden, nicht auf.With ordinary roof tile cutters, however, it is also known to use the Cutting bar moving lever also controls the movement of cutting the brick at the other end Frame. Here, however, the lever connecting the cutting frame and the cutting frame sits on one fixed pivot on the frame. A longitudinal displacement of the connecting lever according to a stencil does not take place. As a result, there are also the disadvantages here, which are eliminated by the subject matter of the invention.

Die Erfindung soll alle Nachteile des bisherigen Antriebes des Schneidrahmenhebels, insbesondere das Ecken und Klemmen der Führungsrolle, in der Schablone, dadurch beseitigen, daß der in der Schablone geführte Arm des zur Bewegung - des Schneidrahmens dienenden Hebels unmittelbar mit dem Schneidbügel gekuppelt ist, so daß er seine Bewegung unmittelbar durch diesen erhält.The invention is intended to remove all of the disadvantages of the previous drive of the cutting frame lever, In particular, eliminate the corners and jamming of the guide roller in the template, that the arm of the lever, which is guided in the template, is used to move the cutting frame directly with the cutting bow is coupled so that it receives its movement directly through this.

Zur Kupplung des in der Schablone geführten Armes des Schneidrahmenhebels mit dem Schneidbügel gemäß der Erfindung dient zweckmäßig eine radial am Schneidbügel und um ihre Längsachse drehbar angeordnete Schlitzführung, in die das freie Ende des Armes eingreift. Die eigenartige Anordnung der Schlitzführung gestattet breite Führungsflächen und der Dicke des Arm en des genau entsprechende Schlitzweite, so daß der Verschleiß zwischen den reibenden Teilen vermindert und toter Gang vermieden wird.For coupling the arm of the cutting frame lever that is guided in the template the cutting bracket according to the invention is expediently used radially on the cutting bracket and Slotted guide rotatably arranged about its longitudinal axis into which the free end of the Poor intervenes. The peculiar arrangement of the slot guide allows wide guide surfaces and the thickness of the arm en of the exactly corresponding slot width, so that the wear between the rubbing parts is reduced and dead gear is avoided.

In der Zeichnung ist eine Ausführungsform der Vorrichtung, die sich gleicherweise für ein, zwei oder mehr Stränge eignet, für zwei Stränge dargestellt, und zwar zeigenIn the drawing is an embodiment of the device, which is equally suitable for a, two or more strands suitable for two strands shown, namely show

Claims

Fig. 2 is a plan view and Fig. 3 is a front view seen against the cutting frame. 4 and 5 show a view and a cross section of the slot guide on the cutting bracket. The cutting frame α is displaceable on the guides b arranged on the side of the carriage w, both in the direction of the strand and across it. The cutting frame is guided parallel to itself by levers d, d 'swinging around fixed vertical pins c, c', which engage with rollers e, e 'in longitudinal slots f, f of the cutting frame α and are connected by a handlebar g to form a guide parallelogram are. The lever k, W used to move the cutting frame according to the template i engages with the arm k on a vertical pin h fixed to the cutting frame α, while the arm W guides itself in the template i with an adjustable guide roller I. The lever k, W is displaceable in a sleeve m, which is rotatable with a pin η about a vertical axis. As a result, the lever can move when it is turned. move hung in the sleeve m so that the guide roller I of the template i. can follow. According to the invention, the arm W is now provided with an extension k ″, which is used to couple the arm W to the cutting yoke 0 by engaging in a radial slot guide of the cutting yoke 0. In the exemplary embodiment, this slot guide f (see also Fig. 4 and 5) arranged and designed in a peculiar manner, insofar as it is rotatably mounted in the cutting yoke 0 with pin q about its longitudinal axis and consequently can follow the lever swinging in the horizontal plane even with wide guide surfaces k "correspond exactly, so that not only the wear is reduced, but also dead gear is avoided. As in the drawing, the cutting bow can be moved by means of a handle r attached to it or a special hand lever attached to its shaft s. The carriage advance can be automatic in a known manner. Ρλ tent claims:

1. Cutting device for extrusion presses with both in the direction of the strand and across it and parallel to itself according to a template forcibly movable cutting frame, characterized in that the in the template

(i) guided arm (W) of the lever (k, W) serving to move the cutting frame (a) is coupled directly to the cutting bow (0).

2. Cutting device according to claim i, characterized in that for coupling the cutting frame lever (k, W) with the cutting bracket (0) a slot guide (p) rotatable radially on the cutting bracket (0) and about its longitudinal axis, into which the end (W ') of the arm (W) engages.
