Vorrichtung an Blechbiegemaschinen zum Kippen der angetriebenen Oberwalze. Patentiert im Deutschen Reiche vom 7. September 1909 ab.Device on sheet metal bending machines for tilting the driven top roller. Patented in the German Empire on September 7, 1909.
Diese Erfindung hat den Zweck, bei Blechbiegemaschinen mit angetriebener Oberwalze bei beendeter Biegearbeit ein sofortiges Kippen der Oberwalze zu ermöglichen, ohne vorheriges Abziehen oder Ausrücken von Rädern und ohne mit außergewöhnlich viel Spiel arbeitenden Antriebsrädern. Die Ober walze ist an einem Ende mit einem Schwanz α versehen, der an seinem Ende in bekannter ίο Weise einen kugelförmigen Ansatz b trägt, auf welchen beim Kippen der Walze eine Druckvorrichtung drückt. Die Oberwalze ist in einem Lager c gelagert, welches in zwei Zapfen d drehbar angeordnet ist. Die Ζάρι 5 fen d sind andererseits in dem festen Ständer e der Maschine fest gelagert. Auf den Kippschwanz α ist das Zahnrad f aufgekeilt, welches in der Weise glockenförmig ausgebildet ist, daß die Mitte des Radkranzes und damit gleichzeitig auch die Mitte des antreibenden Ritzels g mit der Mitte des Drehzapfens d zusammenfällt. Beim Niederdrücken des Kippschwanzes durch die Druckvorrichtung schwenken dann die Zähne des Rades f durch die Zahnlücken des Rades g. The purpose of this invention is to enable sheet metal bending machines with a driven top roll to tilt the top roll immediately after the bending work is complete, without prior pulling or disengagement of wheels and without drive wheels operating with an unusually large amount of play. The upper roller is provided at one end with a tail α , which carries a spherical projection b at its end in a known ίο manner, on which a pressure device presses when the roller is tilted. The top roller is mounted in a bearing c , which is rotatably arranged in two journals d. The Ζάρι 5 fen d are on the other hand firmly stored in the fixed stand e of the machine. On the tilt tail α , the gear f is keyed, which is bell-shaped in such a way that the center of the wheel rim and thus at the same time the center of the driving pinion g coincides with the center of the pivot d . When the tilting tail is pressed down by the pressure device, the teeth of the wheel f then pivot through the tooth gaps of the wheel g.
