KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die den Gegenstand vorliegender Erfindung bildende, zum Niederhalten der Werkstücke an Blechscheeren dienende Vorrichtung zeichnet sich gegenüber bekannten Niederhaltevorrichtungen dadurch aus, dafs sie in ihrem Lager nach zwei Ebenen drehbar ist und demzufolge der Lage und Form des Werkstückes leicht angepafst werden kann.The subject of the present invention, for holding down the workpieces Device serving tin shears is distinguished from known hold-down devices in that it is rotatable in its bearing in two planes and consequently the position and shape of the workpiece can be easily adapted.
Auf der Zeichnung ist eine mit derartigem Niederhalter ausgestattete Scheere durch Fig. 1 bis 3 in Rückansicht, Schnitt und Grundrifs beispielsweise dargestellt.In the drawing, a pair of scissors equipped with such a hold-down device is shown by FIG. 1 to 3 in rear view, section and basic rifs, for example.
Der Niederhalter besteht hier aus einem um den Bolzen b in der Gabel c horizontal drehbaren Hebel d. Die Gabel c selbst ist hierbei wieder senkrecht mit der im Scheerkörper gelagerten Schraube drehbar, so dafs man also den Hebel a in jeder Richtung leicht einstellen und so dem Werkstück bequem anpassen kann. Die senkrechte Einstellung wird auch hier mit Hülfe einer in dem Auge e sich führenden und im Auge f verschraubbaren Handschraube g erreicht. Um hierbei einen ständigen Anschlag des Hebels α an diese Schraube zu erzielen, findet der Hebel jenseits seines Drehpunktes mittelst eines unter Druck einer Feder h stehenden Bolzens i einen Anschlag an einem Nocken k des Scheerkörpers. Bolzen und Feder sind hierbei im Hebel selbst gelagert. An der Stelle, wo die Schraube g den Hebel α berührt, besitzt dieser, wie aus Fig. 2 ersichtlich ist, eine1' Verbreiterung, um beim Drehen des Hebels Spielraum zu bekommen.The hold-down device here consists of a lever d that can be rotated horizontally around the bolt b in the fork c. The fork c itself can again be rotated vertically with the screw mounted in the shear body, so that the lever a can easily be adjusted in any direction and thus easily adapted to the workpiece. Here, too, the vertical adjustment is achieved with the aid of a hand screw g which is guided in the eye e and can be screwed into the eye f . In order to achieve a constant stop of the lever α on this screw, the lever, beyond its pivot point, finds a stop on a cam k of the shear body by means of a pin i which is under pressure from a spring h. The bolt and spring are stored in the lever itself. At the point where the screw g touches the lever α , this has, as can be seen from Fig. 2, a 1 'widening in order to get clearance when turning the lever.
Dieser Niederhalter kann für die verschiedensten Arten Scheeren Anwendung finden.This hold-down device can be used for a wide variety of scissors.
