Description
Die Erfindung betrifft-eine selbstspannende Vorrichtung mit balligen, schrägliegenden Rollen zum Einwalzen von Rohren in Kesselwände oder Flanschen. Die Erfindung selbst besteht darin, daß die Rollen einen Haltewulst haben, der sich auf die Rohrabschnittfläche auflegt. Der hieraus sich ergebende Vorteil gegenüber den bekannten Einwalzvorrichtungen besteht darin, daß die RollenThe invention relates to a self-tightening Device with spherical, inclined rollers for rolling pipes into boiler walls or flanges. The invention itself consists in that the rollers have a retaining bead that rests on the pipe section surface. The resulting advantage over the known rolling-in devices is that the roles
ίο mittels des Haltewulstes an der Einwalzstelle sich selbst festhalten, so daß der Rollenkäfig im weitesten Maße entlastet wird. Dieser kann daher als Gußstück hergestellt werden, so daß durch Fortfall verschiedener Bearbeitungsvorgänge eine wesentliche Verbilligung erzielt wird. Ferner bildet der Wulst einen sicheren Stützpunkt für die schrägliegende Rolle, wodurch eine zylindrische Einwalzung erreicht wird.ίο by means of the retaining bead at the rolling-in point hold yourself tight so that the roller cage is relieved to the greatest possible extent. This can therefore be manufactured as a casting, so that by eliminating various machining operations a substantial reduction in price is achieved. Furthermore, the bead forms a secure support point for the inclined Roll, whereby a cylindrical roll-in is achieved.

Abb. 2 einen senkrechten Schnitt der Vorrichtung in der Arbeitsstellung.Fig. 2 is a vertical section of the device in the working position.
In der Wandung des Käfigs 1 der Vorrichtung sind der Rollenzahl entsprechend schräge Schlitze 2 vorgesehen, in denen die Rollen 3 liegen. In dem Hohlraum 4 steckt der kegelige Teil 6 des Domes 5, der an seinem oberen zylindrischen Teil ein Vierkant 7 als Angriffspunkt der Drehkraft trägt. Die Rollen 3 sind an dem über die Abschnittfläche des Rohres 8 herausragenden Teil mit einem Haltewulst 9 versehen, dessen winklig zur Walzfläche der Rolle abgedrehte Auflagefläche 11 auf die Rohrabschnittfläche zu liegen kommt.In the wall of the cage 1 of the device, the number of rollers are inclined accordingly Slots 2 are provided in which the rollers 3 lie. In the cavity 4 is the conical Part 6 of the dome 5, which is a square 7 on its upper cylindrical part as Point of application of the torque carries. The rollers 3 are on the over the section surface of the Tube 8 protruding part provided with a retaining bead 9, which is angled to Rolling surface of the roller turned bearing surface 11 to lie on the pipe section surface comes.
