KAISERLICHES A IMPERIAL A

PATENTAMT.PATENT OFFICE.

Profileisenbiegemaschinen mit Biegerollen, die mit gegeneinander verstellbaren, zwischen sich Profilteile führenden Ringen versehen sind, sind bekannt, jedoch liegt der Vorteil der Neuerung in der eigenartigen Anordnung und Formung der verstellbaren Ringteile, die es ermöglichen, die meisten gebräuchlichen Profile fest und sicher einzuspannen.Profile iron bending machines with bending rollers, which are adjustable with one another, between are provided with profile parts leading rings are known, but the advantage lies the innovation in the peculiar arrangement and shape of the adjustable ring parts, the make it possible to clamp most common profiles firmly and securely.

Wie aus Fig. ι und 2 ersichtlich, bestehenAs can be seen from Fig. Ι and 2, exist

ίο die zwei feststehenden, angetriebenen Biegewalzen α aus drei in achsialer Richtung beliebig gegeneinander verstellbaren Rollen c, d, f, während die mittlere, verschiebbare und lose laufende Biegewalze g aus zwei achsial gegeneinander verstellbaren Rollen h und i besteht. Die Biegewalze g könnte auch dreiteilig, ähnlich wie die Biegewalze a, ausgeführt werden. Die Abbildungen Fig. 3 bis 7 zeigen verschiedene Beispiele, wie die Rollen sich einstellenίο the two fixed, driven bending rollers α from three axially adjustable rollers c, d, f, while the middle, movable and loosely running bending roller g consists of two axially mutually adjustable rollers h and i . The bending roller g could also be designed in three parts, similar to the bending roller a . Figures 3 to 7 show various examples of how the roles adjust

ao lassen, und es ist ohne weiteres daraus zu ersehen, daß die Biegerollen sich für alle in Frage kommenden Profile gleich gut eignen.ao, and it can be seen without further ado that the bending rollers are suitable for everyone in Question coming profiles are equally well suited.

Die Verstellung der Rollen ist leicht zuAdjusting the roles is easy too

bewerkstelligen, die Vereinfachung der Arbeitsweise,beim Ringbiegen ist dadurch eine erhebliche. accomplish the simplification of the way of working when This makes ring bending a significant one.

Fig. 3 zeigt, wie ein Winkeleisenring mit seinem Schenkel nach innen gebogen wird. Fig. 4 und 5 veranschaulichen das Biegen von T-Eisenringen mit dem Schenkel nach außen bzw. nach innen; bei Fig. 6 liegt der T-Eisenschenkel senkrecht, und in Fig. 7. endlich wird dargestellt, wie Z-Eisen gebogen bzw. eingespannt wird. In jedem Falle wird das betreffende Profil in der vollkommensten Weise eingespannt und geführt.Fig. 3 shows how an angle iron ring is bent with its leg inward. Figures 4 and 5 illustrate the bending of T-iron rings with the leg out or inwards; in Fig. 6 the T-iron leg is perpendicular, and in Fig. 7 it becomes finite shows how Z-iron is bent or clamped. In any case, this will be the case Profile clamped and guided in the most perfect way.

Patent-Ansprüche:Patent Claims: 1. Profileisenbiegemaschinen mit Biegerollen, die aus einem Grundring, einem gegen diesen verschiebbaren zweiten Ring und einer über letzteren übergreifenden verschiebbaren Glocke von gleichem oder annähernd gleichem Außendurchmesser des Grundringes bestehen, dadurch gekennzeichnet, daß der Grundring (d), gegen dessen Stirnfläche sich die Profileisen mit ihrer , unteren Kante legen, achsial verstellbar ist.1. Profile iron bending machines with bending rollers, which consist of a base ring, a second ring displaceable against this and a movable bell over the latter overlapping of the same or approximately the same outer diameter of the base ring, characterized in that the base ring (d), against its end face, the profile iron with its, lower edge, is axially adjustable. 2. Profileisenbiegemaschinen nach Anspruch i, dadurch gekennzeichnet, daß die Gegenbiegerolle (g) nur aus zwei verschiebbaren Ringen (i, h) gleichen Durchmessers besteht.2. Profile iron bending machine according to claim i, characterized in that the counter-bending roller (g) consists of only two displaceable rings (i, h) of the same diameter.
