Description

Die Abkantmaschine dient zum Biegen von Blechen aller Metalle mit bleibenden vorstehenden Flächen in der Biegerichtung durch seitliches Verschieben der Biegewange.The folding machine is used for bending sheet metal of all metals with permanent protruding Surfaces in the bending direction by moving the bending beam sideways.

ίο gehoben und gesenkt werden kann, und aus der Biegewange e. Diese ist in einem durchgehenden offenen Lager f gelagert (Fig. ι und 2). Die Neuerung an der Maschine besteht darin, daß die Biegewange nicht, wie bei Maschinenίο can be raised and lowered, and from the bending beam e. This is stored in a continuous open camp f (Fig. Ι and 2). The innovation on the machine is that the bending beam is not, as is the case with machines

Auf Maschinen alter Konstruktion war es bisher nur möglich, Bleche in der ganzen eingespannten Breite abzukanten. Soll aber nur ein Teil des Bleches abgekantet werden, so mußte das geradebleibende Stück mitgebogen und nachher zunickgehämmert werden, was den Arbeitsgang verlängerte und die fertige Arbeit unsauber machte. Kommen jetzt solche Arbeiten vor, so wird die Biegewange e nur nach links oder nach rechts verschoben. (Fig. 3), bis die Wange die abzukantende Fläche trifft, so daß das übrige vorstehende Blech gerade bleibt. Ebenso ist es möglich, beliebig breite Biegewangen in das Lager f einzuführen (Fig. 4), um Ecken an Bleche zu biegen, die an beiden Seiten gerade bleiben und nur in der Mitte oder an mehreren Stellen des Bleches abgekantet werden sollen.Up until now, it was only possible to bend sheet metal in the entire clamped width on machines of old construction. But if only part of the sheet is to be folded, the piece that remained straight had to be bent and then hammered down, which lengthened the process and made the finished work unclean. If such work occurs now, the bending beam e is only shifted to the left or to the right. (Fig. 3), until the cheek meets the beveled surface so that the rest of the protruding sheet remains straight. It is also possible to insert any width of bending cheeks into the bearing f (Fig. 4) in order to bend corners on sheets that remain straight on both sides and are only to be folded in the middle or at several points on the sheet.

Es lassen sich auch alle anderen Arbeiten ausführen, die auf den Maschinen alter Konstruktion ausgeführt werden. Der Fortfall der Gegengewichte wird durch Anbringung entsprechend langer Hebel an der Biegewange e ausgeglichen, die aber in der Zeichnung als nebensächlich weggelassen wurden. Ebenso ist nur der rechte Teil der Maschine gezeichnet (Fig. 2), da die linke Seite ebenso gearbeitet ist.All other work can also be carried out on the machines of the old construction are executed. The elimination of the counterweights is achieved by attaching appropriately long levers to the bending beam e compensated, which, however, were left out in the drawing as irrelevant. Likewise, only the right part of the machine is drawn (Fig. 2), since the left side is the same is worked.
