Description
Es sind Vorrichtungen zum Anrollen der Enden von Rohren bekannt, bei denen der Werkzeugkopf einen in das zylindrische Werkstück hineinpassenden Ansatz aufweist, der den Rand des Werkstückes zwangläufig zu ; den Bördelrollen führt. jThere are devices for rolling the ends of pipes are known in which the Tool head has a fitting in the cylindrical workpiece approach, the the edge of the workpiece inevitably closed; the flanging rollers. j
Werden dünnwandige Blechzargen von ! großem Durchmesser mit solchen Bördelköpfen bearbeitet, so tritt der Nachteil auf, daß derAre thin-walled sheet metal frames from! large diameter with such crimping heads edited, the disadvantage arises that the
ίο durch das Anrollen erweiterte Rand der Zarge j unrund wird, was auch nicht durch die mehrfache Anordnung von Bördelrollen auf dem ; Umfange des Werkzeuges sicher verhindert werden kann, da der zwischen den Rollenίο the edge of the frame expanded by rolling j becomes out of round, which is also not due to the multiple arrangement of flanging rollers on the; Scope of the tool can be safely prevented because between the rollers
is liegende Blechrand verzogen wird.is lying sheet edge is warped.
Nach der Erfindung wird dieser Nachteil auch bei dem Vorhandensein nur einer einzigen Bördelrolle dadurch vollständig behoben, daß der in die Blechzarge hineinragende Ansatz des Bördelkopfes auf seinem Umfange in der Höhe der Arbeitskante der Bördelrolle einen dem Profil des erweiterten Randes der Blechzarge entsprechenden Führungsrand aufweist, durch den der Zargenrand bis zum Fertigstellen des Bordes ständig eine genaue zwangläufige Führung erhält, die ein seitliches Ausweichen des Randes verhindert. Gleichzeitig wird durch diesen Rand vermieden, daß die Zarge sich schief zum Bördelkopf einstellen kann.According to the invention, this disadvantage becomes even in the presence of only one Flanging roller completely eliminated by the fact that the approach protruding into the sheet metal frame of the crimping head on its circumference at the level of the working edge of the crimping roller has a guide edge corresponding to the profile of the widened edge of the sheet metal frame, through which the frame edge constantly receives an exact, inevitable guidance until the board is finished, a lateral Avoidance of the edge prevented. At the same time, this edge avoids that the frame can adjust at an angle to the crimping head.
In der Zeichnung ist der neue Bördelkopf in einer als Beispiel dienenden Ausführungsform dargestellt. In the drawing, the new crimping head is shown in an embodiment serving as an example.
Der in eine Verschlußmaschine einsetzbare Kopf α (Abb. ι und 2) ist mit einem vorspringenden, in die zu bearbeitende Zarge hineinpassenden Ansatz b versehen, in dessen Umfang nur eine einzige Bördelrolle d angeordnet ist. Der Ansatz b leitet den oberen Blechrand der Zarge c zwangläufig zu der Arbeitsfläche der Bördelrolle d, so daß durch das Gegeneinanderbewegen von Zarge c und dem sich drehenden Bördelkopf α durch die Rolle d ein Bord f gebildet wird, wie dies Abb. 2 zeigt. Der Ansatz b am Kopfe α bildet mit dem seitlich vorspringenden Rande e zu sammen das gleiche Profil, wie es der erweiterte Rand der Blechzarge aufweist, so daß der von der Rolle erzeugte Zargenrand in jeder Lage am Ansatz b eine gute Führung erhält. Beim Gegeneinanderbewegen von Zarge c und Bördelkopf α kann also die obere öffnung der Zarge c nie unrund werden und der Blechrand nie nach innen ausweichen. The head α (Fig. Ι and 2) which can be used in a sealing machine is provided with a protruding shoulder b which fits into the frame to be machined and in the circumference of which only a single crimping roller d is arranged. The approach b directs the upper sheet metal edge of the frame c inevitably to the working surface of the crimping roller d, so that by moving the frame c and the rotating crimping head α against each other through the roller d, a rim f is formed, as shown in Fig. 2. The approach b on the head α forms with the laterally protruding edge e together the same profile as the expanded edge of the sheet metal frame, so that the frame edge generated by the roll receives good guidance in every position on the approach b. When frame c and crimping head α move against one another, the upper opening of frame c can never become out of round and the sheet metal edge can never move inward.
