Description

Bei- der dem Hauptpatent zugrunde liegenden Ausbildung der Schrottschere wird die hin und her gehende Schwungbewegung des pendelnd aufgehängten Rahmens, der als Führung für die beiden Messerträger dient, unter Zuhilfenahme von Gabeln und Exzentern, die auf der Antriebswelle angeordnet sind, herbeigeführt. Diese Ausführung soll erfindungsgemäß vereinfacht werden. Zu diesem Zwecke wird der Führungsrahmen nicht mehr unmittelbar pendelnd aufgehängt und ebenfalls nicht mehr unmittelbar von der Antriebswelle vermittels der obengenannten Exzenter hin und her bewegt. Das Neue besteht darin, daß bei Anwendung der an sich bekannten Maßnahme, das eine Messer am Gehäuse des Gegenmessers zu führen, der Träger des von der Pendelachse entfernter angeordneten Messers als eine um die genannte Achse schwingbare Kurbelschwinge ausgebildet ist, auf welcher der das der Pendelachse näherliegende Messer tragende Rahmen geführt ist.Both the scrap shear design on which the main patent is based is the reciprocating swinging movement of the pendularly suspended frame, which serves as a guide serves for the two knife carriers, with the help of forks and eccentrics, the are arranged on the drive shaft, brought about. This embodiment is intended according to the invention be simplified. For this purpose, the guide frame is no longer immediate suspended pendulum and also no longer directly mediated by the drive shaft the above eccentric moves back and forth. What is new is that when it is applied the known measure, the one knife on the housing of the counter knife to guide, the carrier of the knife arranged further away from the pendulum axis than one that can be pivoted about said axis Crank rocker is formed on which the knife closer to the pendulum axis load-bearing frame is performed.

In der Zeichnung ist die Ausführungsform der Erfindung schematisch dargestellt, und zwar zeigtIn the drawing, the embodiment of the invention is shown schematically, and although shows

Abb. 2 eine Draufsicht erkennen läßt.Fig. 2 shows a plan view.

Mit ι und 2 sind die Kreismesser der Saumschere bezeichnet, deren Ständer durch 3 angedeutet ist. Ebenso wie bei der dem Hauptpatent zugrunde liegenden Bauart dient ein geschlossener Kanal 17 zur Zuführung der Säume von der Saumschere zur Schrott schere, deren beide Messerg und 10 heißen. Das Messer 10 ist an der gabelförmigen Kurbelschwinge 16 ,angeordnet, die an die Kurbel ι s der Welle 11 angreift. Mit den Kurbeln 13' an der Welle 11 sind Zugstangen 13 verbunden, die bei 13" gelenkig mit dem Rahmen 7 verbunden sind. In dem Rahmen 7 ist die vorgenannte Kurbelschwinge 16 geradlinig geführt. Sie tritt bei 18 aus dem genannten Rahmen 7 heraus und ist pendelnd bei 6 aufgehängt. Das Messer 9 ist in dem Führungsrahmen 7 für die wiederholt genannte Kurbelschwinge 16 befestigt.With ι and 2 the circular knives of the hemming scissors are designated, the stand by 3 is indicated. As is the case with the design on which the main patent is based a closed channel 17 for feeding the hems from the hemming shears to the scrap shears, both of which are called Messerg and 10. The knife 10 is on the fork-shaped crank arm 16, which engages the crank ι s of the shaft 11. With the cranks 13 'on the shaft 11 tie rods 13 are connected, which are articulated to the frame 7 at 13 ". In the frame 7 is the aforementioned crank arm 16 out in a straight line. She kicks off the said at 18 Frame 7 and is suspended at 6 in a pendulum fashion. The knife 9 is in the guide frame 7 attached for the repeatedly mentioned crank arm 16.

Es ist ersichtlich, daß beim Drehen der Welle 11 die Kurbelschwinge 16 außer einer schwingenden Hinundherbewegung eine gerad- 5" linige Bewegung entgegen dem Messer 9 macht und daß vermittels der Zugstangen 3 der Rahmen 7 in entgegengesetzter Richtung bewegt wird. Während der Schneidbewegung der beiden Messer führen diese also gleich- S? zeitig die schwingende Hinundherbewegung aus, so daß beim Schneidhub der Messer beide in Richtung der Bewegung des Blechsaumes bewegt werden und daß während der Zurückbewegung der Messer diese sich öffnen, um daran anschließend den nächsten Schneidhub bei gleichzeitiger Bewegung in Richtung des bewegten Blechsaumes durchzuführen. It can be seen that when rotating the shaft 11, the crank arm 16 except for one oscillating back and forth movement a straight 5 "linear movement against the knife 9 makes and that by means of the tie rods 3 of the frame 7 in the opposite direction is moved. So during the cutting movement of the two knives, they lead equally - S? early the oscillating back and forth movement, so that during the cutting stroke of the knife both in the direction of the movement of the sheet metal seam are moved and that during the return movement of the knife this open in order to then start the next cutting stroke with simultaneous movement in In the direction of the moving sheet metal seam.
