Description

In dem Hauptpatent 344097 ist eine Blechschere mit gradlinig bewegtem Obermesserhalter zum Teilen, Besäumen und Spalten von Blechtafeln beschrieben, bei welcher der Neigungswinkel der Schneidkante des Obermessers 7 durch Heben oder Senken des Obermesserhalters an dem dem Quermesser 9 zugehörigen Ende veränderbar ist. Das Heben und Senken des Obermesserhalters erfolgt nach diesem Hauptpatent durch Verlegen der Drehachse der diesem Obermesserhalterende zugehörigen Schwinge, und zwar entweder durch ein der Schwinge als Lagerbolzen dienendes Exzenter oder durch Winkelverstellung der diesem Obermesserhalterende zugehörigen Schwinge.In the main patent 344097 is a tin snips with a straight moving upper knife holder for dividing, trimming and splitting of metal sheets described, in which the angle of inclination the cutting edge of the upper knife 7 by raising or lowering the upper knife holder can be changed at the end associated with the transverse knife 9. The lifting and lowering of the upper knife holder is carried out according to this main patent by laying the Axis of rotation of the rocker arm associated with this upper knife holder end, either by means of an eccentric which serves as a bearing pin for the rocker or by adjusting the angle the rocker arm associated with this upper knife holder end.

Auf Grund vorliegender Zusatzerfindung ist das Obermesser nicht mehr an einem Ende hebbar und senkbar, sondern an seinen beiden Enden. Dies wird erreicht dadurch, daß die Druckstelzen 2, welche von den Schwingen 3, 4 betätigt werden, in ihrer Länge veränderbar sind. Zu dem Zwecke tragen die Druckstelzen 2 Mutterhülsen a, die bei b an den Druckstelzen angelenkt sind. In diese Mutterhülsen greifen Schrauben c, die beliebig von einem Schneckengetriebe gedreht werden können. Zu dem Zwecke tragen die Schrauben c Schneckenräder el in Büchsen e. In diese greifen die Schnecken g einer Welle h, die in geeigneten Lagerbüchsen gelagert sind und mittels Handkurbel gedreht werden können. Stellmuttern / verhindern das selbsttätige Drehen der Schrauben c und legen diese fest. Da die Stellvorrichtungen an beiden Enden des Obermesserhalters angebracht sind, kann man behufs Veränderung der Neigung des Obermessers eine oder die beiden Stellvorrichtungen in Anwendung bringen. Auch kann man die beiden Stellvorrichtungen kuppeln, um sie gemeinschaftlich zu betätigen.Due to the present additional invention, the upper knife can no longer be raised and lowered at one end, but rather at both ends. This is achieved in that the pressure stilts 2, which are actuated by the rockers 3, 4, can be changed in their length. For this purpose, the pressure stilts carry 2 nut sleeves a, which are hinged to the pressure stilts at b. Screws c, which can be rotated as required by a worm gear, engage in these nut sleeves. For this purpose, the screws c worm gears el in bushes e. The worms g of a shaft h, which are mounted in suitable bearing bushes and can be turned by means of a hand crank, engage in this. Adjusting nuts / prevent the screws c from turning automatically and fix them. Since the adjusting devices are attached to both ends of the upper knife holder, one or both adjusting devices can be used to change the inclination of the upper knife. You can also couple the two actuating devices in order to operate them together.

Um bei dieser Einrichtung die Schräglage des Obermessers zum Untermesser angeben zu können, also anzugeben, in welchem Schneidwinkel das Obermesser zum Untermesser steht, ist folgende Anordnung getroffen:In order to specify the inclination of the upper knife to the lower knife with this device to be able to, i.e. to indicate at which cutting angle the upper knife to the lower knife the following arrangement is made:

An dem Obermesserhalter ι ist der Zeiger η mit dem Bolzen ο drehbar befestigt und wird durch das Gegengewicht ρ immer in der gleichen Lage gehalten. Der Spitze des Zeigers η gegenüber ist an dem Obermesserhalter eine Skala r angebracht. Wird nun der Obermesserhalter in eine andere Schräglage gebracht, so bleibt der Zeiger ti in seiner Stellung stehen und die Schräglage des Obermesserhalters und damit des Obermessers wird an der Skala r angezeigt. The pointer η is rotatably attached to the upper knife holder ι with the bolt ο and is always held in the same position by the counterweight ρ. A scale r is attached to the upper knife holder opposite the tip of the pointer η. If the upper knife holder is now brought into a different inclined position, the pointer ti remains in its position and the inclined position of the upper knife holder and thus of the upper knife is displayed on the scale r .
