Description
Beschreibung
Die bisher verwendeten Rollen erlauben nur das Biegen von Bögen mit einem Radius, müssen also für jeden verschiedenen Halbmesser ausgewechselt werden. Dann gibt es Geräte mit zwei verschiedenen Radien, mit denen aber einer der Bögen nur bis 450 gebogen werden kann.The roles used so far only allow the bending of arcs with a radius, so they have to be changed for each different radius. Then there are devices with two different radii, but with one of the arches can only be bent to 450.
Diese Geräte haben den Nachteil, daß Rolle sowie Festhaltebolzen und Mitnehmerbolzen beim Biegen eines einzigen Stabstahles mit vorgeschriebenen Radien ein-oder mehrmals ausgewechselt werden müssen, und zwar alle drei Teile. Das ist vor allem bei starken Stählen wegen der Schwere der Rollen sehr umständlich.These devices have the disadvantage that role as well as retaining bolts and Driving pins when bending a single steel bar with prescribed radii need to be replaced one or more times, all three parts. That is Particularly cumbersome with strong steels because of the weight of the rollers.
Die Neuerung dient dem Zweck, dieses Auswechseln zu vermeiden. Deshalb hat die Rolle (1) zwei in einem bestimmten Verhältnis zueinander stehende Bögen (2u. 3), die beide für eine Biegung von 1800 ausreichen. Drehpunkt ist Punkt (4).The purpose of the innovation is to avoid this replacement. That's why the role (1) has two arcs which are in a certain ratio to one another (2u. 3), both of which are sufficient for a bend of 1800. The pivot point is point (4).
Die Rolle wird durch einen Verbindungsbolzen (5) mit dem Biegearm der Maschine verbunden. Da der kleinere Radius (2) nur für Endhaken bestimmt ist, wird das Ende durch Einlegen in die Nut (6) der Walze mitgenommen. Es wird also nur für das Biegen der großen Bögen der übliche Mitnehmerbolzen (7) benötigt. Dieser braucht aber beim Biegen der kleinen Kurve nicht entfernt zu werden.The roller is connected to the bending arm by means of a connecting bolt (5) connected to the machine. Since the smaller radius (2) is only intended for end hooks, the end is taken along by inserting it into the groove (6) of the roller. So it will The usual driving pin (7) is only required for bending the large arches. This does not need to be removed when the small curve is bent.
Um das Auswechseln der Festhaltebolzen zu sparen, ist ein Schlitten (8) vorgesehen, der zwei Festhaltebolzen (9 u. lo) trägt, die in ihrem Abstand der Differenz der beiden Kurvenradien entsprechen.To save the need to change the retaining bolts, there is a slide (8) provided, which carries two retaining bolts (9 u. Lo), which in their distance of The difference between the two curve radii.
Die Nut (6) kann auf ganze Rollenlänge durchgeführt werden
