Description

Gegenstand der Erfindung ist eine Vorrichtung zur Herstellung von Dachrinnen, bei welcher die Herstellung des Wulstes und der Rundung am gleichen Ort in der Vorrichtung erfolgt, indem zuerst in einer Wulstvorrichtung mittels Wulststabes und Kurbel der Wulst hergestellt und das Blech beim Runden zur Dachrinne durch die Wulstvorrichtung "festgehalten wird.The invention is a device for the production of Gutters in which the manufacture of the bulge and the rounding are the same Place in the device is done by first in a bead device by means of a bead rod and crank the bead made and the sheet metal while rounding to the gutter through the Bead device "is held.

Bei einer bekannten Vorrichtung dieser Art geschieht das Biegen des Bleches mit einem dem Metallrücken ähnlichen Verfahren. Wulstvorrichtung und Biegewalze sind getrennt, so daß bei einer Einspannung des Bleches in der -Wülstvörrichtung keine vollkommene Rundung erzielt wird; auf den Wulst folgt erst eine gerade Strecke, dann die Rundung. Auch ist nicht sicher gewährleistet, daß zur jeweiligen Rundungsgröße immer die richtige Wulstgröße hergestellt wird, denn je nach der verwendeten Biegewalze muß die passende Wulstgröße in der Vorrichtung besonders eingestellt werden.In a known device of this type, the bending happens Sheet metal with a process similar to the metal back. Bead device and bending roller are separated so that when the sheet is clamped in the -Wülstvörrichtung no perfect rounding is achieved; the bead is only followed by a straight stretch, then the rounding. There is also no guarantee that the respective rounding size will be used the correct bead size is always produced, depending on the bending roll used the appropriate bead size must be specially set in the device.

Die Erfindung vermeidet diese Nachteile und führt zu einer wesentlich einfacheren und sicherer arbeitenden Vorrichtung. Sie ist dadurch ge1cennzeichnet, daß die Wulstvorrichtung c auf der Mantelfläche der Biegewalze b achsparallel befestigt ist, auf der das Blech a durch eine Andrückwalze i gerundet wird.The invention avoids these disadvantages and leads to one substantial simpler and safer working device. It is characterized by that the bead device c attached to the outer surface of the bending roller b axially parallel is, on which the sheet a is rounded by a pressure roller i.

Das Biegen des Bleches erfolgt somit nach einem Walzverfahren, das an sich bekannt ist und sich bestens bewährt hat. Es ermöglicht ein einfaches, leichtes und wenig Kraft erforderndes Arbeiten. Außerdem werden vollkommene Rundungen erzielt. Die Einheit Biegewalze-Wulstvorrichtung bedingt zudem, daß zur jeweiligen Rundungsgröße zwangläufig immer die richtige Wulstgröße hergestellt wird. Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The sheet is bent using a rolling process that is known per se and has proven itself very well. It enables a simple, easy and work requiring little strength. In addition, perfect curves are achieved. The unit bending roll-bead device also requires that the respective rounding size inevitably the correct bead size is always produced. The drawing shows an embodiment of the invention.

Abb. z zeigt die Vorrichtung bei der Herstellung des Wulstes; Abb. 2 bei der Herstellung der Rundung.Fig. Z shows the device in the manufacture of the bead; Fig. 2 when making the rounding.

Ein Blechzuschnitt a wird auf der Hauptwalze b liegend in die Führungsschiene c und den darin befindlichen, an sich bekannten Wulststab d eingelegt. Durch Drehen der Kurbel e bildet sich der Wulst f. Anschließend wird nach dem üblichen Ziehen des Wulststabes d durch Betätigung der Kurbel g die Walze b mitsamt der Führungsschiene c bewegt und der Blechzuschnitt a so mitgenommen. Eine Andrückwalze i drückt dabei das Blech auf die Hauptwalze b und rundet es. Die Walze i sitzt auf einem Hebelarm j, der bei h gelagert ist und .am anderen Ende eine Arretierung Z trägt, die die Hauptwalze b bei der Herstellung des Wulstes festhält.A sheet metal blank a is placed lying on the main roller b in the guide rail c and the bead rod d located therein, known per se. The bead f is formed by turning the crank e. Then, after the usual pulling of the bead bar d, the roller b is moved together with the guide rail c by actuating the crank g and the sheet metal blank a is carried along. A pressure roller i presses the sheet metal onto the main roller b and rounds it off. The roller i is seated on a lever arm j which is mounted at h and at the other end carries a lock Z which holds the main roller b in place during the manufacture of the bead.
