Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Gegenstand der Erfindung ist eine ro tie-, rende Schere, die zum Durchschneiden der aus den Walzen tretenden Stab- und kleinen Formeisen dient. Von den bekannten Scheren dieser Art, deren Scherenblätter durch die Rotation des ganzen Scherenkörpers geöffnet und geschlossen werden, unterscheidet sich die neue Schere dadurch, daß das eine Scherenblatt mittels Hebels nicht durch eine entsprechend ausgebildete Kurvenscheibe, sondern mittels eines Winkelhebels und einer an einen exzentrischen Zapfen angelenkten Pleuelstange bewegt wird.The object of the invention is a rotating, rende scissors, which are used to cut through the out the rollers are used for bar and small shaped iron. From the well-known scissors of this type, the blades of which are opened by the rotation of the entire body of the scissors and are closed, the new pair of scissors differs in that one scissor blade by means of a lever, not through a correspondingly designed cam, but by means of an angle lever and a connecting rod hinged to an eccentric pin is moved.

In der Fig. ι ist die Schere im Schnitt und in der Fig. 2 in Seitenansicht dargestellt.In Fig. Ι the scissors are shown in section and in Fig. 2 in side view.

Die Einrichtung und Wirkungsweise ist folgende :The setup and mode of operation is as follows:

An der auf der Antriebswelle sitzenden Scheibe α ist der das bewegliche Scherenmesser tragende Winkelhebel b mittels der Achse c drehbar gelagert. Der andere Schenkel des Winkelhebels b endigt in einen Zapfen d, an welchen eine Schubstange e angelenkt ist, deren anderes Ende mit einem festen, aber exzentrisch zur Scheibe α angeordneten Zapfen f verbunden ist. Wird die Scheibe a in Drehung versetzt, so dreht sich der Zapfen c des Winkelhebels b um den Mittelpunkt der Scheibe a; die Schubstange e und der Zapfen d dagegen drehen sich um den festen Zapfen f, wodurch die Schere geöffnet und geschlossen wird. On the disk α seated on the drive shaft, the angle lever b carrying the movable scissor knife is rotatably mounted by means of the axis c. The other leg of the angle lever b ends in a pin d to which a push rod e is articulated, the other end of which is connected to a fixed but eccentrically arranged pin f to the disk α . If the disk a is set in rotation, the pin c of the angle lever b rotates around the center of the disk a ; the push rod e and the pin d, however, rotate around the fixed pin f, whereby the scissors are opened and closed.

Der Vorteil gegenüber den rotierenden Scheren, welche durch Anschläge oder Kurvenscheiben bewegt werden, besteht in dem ruhigen Arbeiten und in der Verwendungsmöglichkeit bei größerer Walzeisengeschwindigkeit.The advantage over rotating scissors, which are provided by stops or cam disks are moved, consists in the quiet work and in the possibility of use at higher roll iron speed.
