Description

Die Erfindung betrifft eine Biegewange für Abkantmaschinen, die in den beiden Biegewangenhebeln in der Höhenrichtung verstellbar und zur vertikalen Achse abdrehbar befestigt ist. Durch diese Anordnung der Biegewange wird der Arbeitsbereich der Abkantmaschinen bedeutend erweitert. So können z. B. langschenklige Bleche mit niedrigen Stufen ohne besondere Vorrichtungen gebogen werden. Bei ähnlichen Konstruktionen ist dies zwar auch möglich, doch ist hier die Biegewange in waagerechter Richtung verschiebbar angeordnet. Dies hat den Nachteil, daß die Biegewange wesentlich langer gebaut ts werden muß als bei normalen Maschinen. Ferner werden die Druck- und Drehmomente von den Biegewangenhebeln viel ungünstiger aufgenommen, als dies bei normalen Abkantmaschinen der Fall ist. Diese Übelstände sind bei vorliegender Erfindung behoben.The invention relates to a bending beam for folding machines, which are in the two bending beam levers is adjustable in the height direction and attached rotatable to the vertical axis. This arrangement of the bending beam The working range of the folding machines is significantly expanded. So z. B. long-legged sheets with low Steps can be bent without special devices. With similar constructions this is also possible, but here the bending beam can be moved in the horizontal direction arranged. This has the disadvantage that the bending beam is built much longer ts than with normal machines. Furthermore, the pressure and torque absorbed by the bending beam levers much less favorably than with normal folding machines the case is. These inconveniences are remedied in the present invention.

In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigen:The subject of the invention is shown in the drawing, namely show:

Abb. ι die Biegewange in normaler Stellung im Querschnitt,Fig. Ι the bending beam in the normal position in cross section,

Abb. 2 die Biegewange in der zur senkrechten Achse abgedrehten Stellung,Fig. 2 the bending beam in the turned position to the vertical axis,

Abb. 3 die Gesamtanordnung in der Ansicht von vorn,Fig. 3 shows the overall arrangement from the front,

Abb. 4 einen Schnitt durch den Biegewangenhebel der Biegewange· und die Abdrehmutter im Grundriß nach Abb. 1.Fig. 4 shows a section through the bending beam lever of the bending beam · and the twist-off nut in plan according to Fig. 1.

Die Biegewange A ist in den beiden Biegewangenhebeln B T-förmig geführt. Die Verstellung der Biegewange in der Höhenrichtung erfolgt in bekannter Weise durch die Spindeln C und die Muttern D. Die Muttern D sind zylindrisch ausgeführt und prismatisch in den Biegewangenhebeln B geführt, so daß beim Drehen der Biegewange die Spindeln entlastet sind. Die Biegewange A kann um die Muttern D gedreht werden. Der Drehung entsprechend sind die Führungen abgeschrägt. Der Grad der Abschrägung begrenzt die Abdrehbewegung. Die Abdrehung der Biegewange erfolgt durch die Spindeln E und die ebenfalls zylindrisch ausgebildeten Muttern F. Durch die Muttern G wird die Biegewange A festgestellt. Bei jeder Verstellung müssen vorher die Mutter G gelöst werden. Für die Höhenverstellung sind in den Biegewangenhebeln B entsprechende Langlöcher H vorgesehen. The bending beam A is guided in a T-shape in the two bending beam levers B. The height direction of the bending beam is adjusted in a known manner by the spindles C and the nuts D. The nuts D are cylindrical and prismatically guided in the bending beam levers B so that the spindles are relieved when the bending beam is rotated. The bending beam A can be rotated around the nuts D. The guides are beveled according to the rotation. The degree of bevel limits the turning movement. The bending cheek is turned by means of the spindles E and the nuts F, which are also cylindrical. With the nuts G, the bending cheek A is fixed. The nut G must be loosened before each adjustment. Corresponding elongated holes H are provided in the bending beam levers B for height adjustment.
