The invention relates to a roll forming device for roll forming sheet metal strips, comprising a frame (2) and a number of pairs of rolls (6, 7). These pairs of rolls are placed one behind the other in a strip advancing direction, are arranged opposite one another in a parallel manner while forming a profiled gap (S) therebetween, through which the sheet metal strip to be processed passes, and thy can be rotationally driven. Said rolls (6, 7) are subdivided in a manner that is transversal to the strip advancing direction into first roll segments (6a, 7a) and second roll segments (6b, 7b), and at least the second roll segments (6b) can be moved transversal to the strip advancing direction. The inventive device is characterized in that the roll segments (6a, 6b, 7a, 7b) each comprises a base body (10), which is provided in the form of a hollow shaft, is held in a rotationally fixed manner on a shaft (9) that is mounted on the frame (2), and which can be axially removed therefrom. Said roll segments also comprise a number of profiled elements (11), which define a roll profile (11a), are held in a rotationally fixed manner on the base body (10) while lying next to one another, and which are detachably joined thereto.

Description

Rollformeinrichtung zum Rollformen von Blechbändern und Rollensegment für eine solche RollformeinrichtungRoll forming device for roll forming sheet metal strips and roll segment for such a roll forming device
Die vorliegende Erfindung betrifft eine Rollformeinrichtung zum Rollformen von Blechbändern mit einem Gestell und mehreren, in einer Bandförderrichtung hintereinander angeordneten Paaren von Rollen, die in paralleler Ausrichtung einander gegenüberliegend unter Bildung eines dazwischen liegenden profilierten Spalts für die Durchführung des zu bearbeitenden Blechbandes angeordnet und rotierend antreibbar sind, wobei die Rollen jeweils quer zur Bandförderrichtung in erste Rollensegmente und zweite Rollensegmente unterteilt sind und zumindest die zweiten Rollensegmente quer zur Bandführungsrichtung bewegt werden können. Desweiteren betrifft die Erfindung ein Rollensegment für eine solche Rollenformeinrichtung.The present invention relates to a roll forming device for roll forming sheet metal strips with a frame and a plurality of pairs of rolls arranged one behind the other in a strip conveying direction, which are arranged in a parallel orientation opposite one another to form an intermediate profiled gap for the passage of the sheet metal strip to be processed and can be driven in rotation , wherein the rollers are divided transversely to the belt conveying direction into first roller segments and second roller segments and at least the second roller segments can be moved transversely to the belt guide direction. Furthermore, the invention relates to a roller segment for such a roll forming device.
Rollformeinrichtungen der vorgenannten Art sind beispielsweise aus dem US- Patent 4,811 ,587 bekannt und werden in der Praxis eingesetzt, um im Durchlaufverfahren Blechbänder, die von einem Coil abgewickelt werden, mit einem Profil zu versehen bzw. an den Randbereichen der Blechbänder aufrecht abragende Stege herzustellen. Dazu werden die Blechbänder zwischen den Rollenpaaren hindurch geführt, die an ihrem Außenumfang zueinander korrespondierende Rollprofile aufweisen, um das Blechband, wenn es zwischen den Rollen hindurchläuft, unter Druck zu verformen.Roll forming devices of the aforementioned type are known, for example, from US Pat. No. 4,811,587 and are used in practice to provide sheet metal strips which are unwound from a coil with a profile in a continuous process or to produce upright webs protruding from the edge regions of the sheet metal strips , For this purpose, the metal strips are passed between the pairs of rollers, which have corresponding rolling profiles on their outer circumference, in order to deform the metal strip under pressure when it runs between the rollers.
Bei den bekannten Rollformeinrichtungen werden die Rollen jeweils durch zwei Rollensegmente gebildet, die an seitlichen Trägern des Gestells drehbar gelagert und durch eine Übertragungswelle miteinander verbunden sind, so daß nur ein Rollensegment angetrieben zu werden braucht. Dabei kann einer der Gestellträger quer zur Bandförderrichtung der Rollformeinrichtung nach außen verfahren werden, so daß die Maschinenbreite an die Breite des zu bearbeitenden Blechbands angepaßt werden kann.In the known roll forming devices, the rolls are each formed by two roll segments, which are rotatably mounted on lateral supports of the frame and are connected to one another by a transmission shaft, so that only one roll segment needs to be driven. One of the frame supports can be moved outwards transversely to the belt conveying direction of the roll forming device, so that the machine width can be adapted to the width of the sheet metal strip to be processed.
Die bekannten Rollformeinrichtungen haben sich in der Praxis durchaus bewährt. Als problematisch wird jedoch teilweise angesehen, daß die Rollformeinrichtungen nur sehr schwer für die Herstellung unterschiedlicher Blechprofile umgerüstet werden können. Hierzu ist es nämlich erforderlich, die Rollensegmente als Ganzes auszutauschen.The known roll forming devices have proven themselves in practice. However, it is considered to be problematic in some cases that the roll forming devices can only be converted with great difficulty for the production of different sheet metal profiles. This is because it is necessary to replace the roller segments as a whole.
Aufgabe der Erfindung ist es daher, eine Rollformeinrichtung der eingangs genannten Art so auszubilden, daß ein Umrüsten auf unterschiedliche Blechprofile auf einfache Weise möglich ist. Diese Aufgabe ist bei einer Rollformeinrichtung der eingangs genannten Art dadurch gelöst, daß die Rollensegmente jeweils einen als Hohlwelle ausgebildeten Grundkörper, der auf einer am Gestell angeordneten Welle drehfest gehalten ist und von dieser axial abgezogen werden kann, und mehrere ein Rollprofil definierende Profilelemente, die nebeneinander liegend an dem Grundkörper drehfest gehalten und mit diesem lösbar verbunden sind, aufweisen. Entsprechend ist das erfindungsgemäße Rollensegment dadurch gekennzeichnet, daß es einen als Hohlwelle ausgebildeten Grundkörper und mehrere das Rollprofil definierende Profilelemente, die nebeneinander liegend an dem Grundkörper drehfest gehalten und mit diesem lösbar verbunden sind, aufweist. Erfindungsgemäß sind die Rollensegmente somit als Module ausgebildet, die auf fest am Gestell vorgesehene Wellen aufgeschoben werden können, so daß sie mit wenig Aufwand montiert und demontiert werden können. Hinsichtlich weiterer vorteilhafter Ausgestaltungen der Erfindung wird auf dieThe object of the invention is therefore to design a roll forming device of the type mentioned at the outset in such a way that a changeover to different sheet metal profiles is possible in a simple manner. This object is achieved in a roll forming device of the type mentioned above in that the roller segments each have a base body designed as a hollow shaft, which is held in a rotationally fixed manner on a shaft arranged on the frame and can be pulled off axially from it, and several profile elements defining a roll profile, which are arranged side by side horizontally held on the base body and releasably connected to it. Correspondingly, the roller segment according to the invention is characterized in that it has a base body designed as a hollow shaft and a plurality of profile elements defining the roller profile, which are held next to one another in a rotationally fixed manner on the base body and are detachably connected to it.
