KAISERLICHES A IMPERIAL A
PATENTAMT.PATENT OFFICE.
Die Erfindung stellt eine Ziehzange dar, die in der Hauptsache den Zweck hat, möglichst wenig Stoff des zu ziehenden Stabes zum Festklemmen zu beanspruchen, indem ihre Form es ermöglicht, ganz zwischen die Walzen einer rotierenden Matrize einzugreifen. . 'The invention represents a drawing pliers, the main purpose of which is to be as possible to take up little material of the rod to be drawn to clamp it, because its shape allows it to be completely between the Engage rolling a rotating die. . '
Wie aus der Zeichnung ersichtlich, besteht die Zange aus zwei Schenkeln Ct1 und Ct2, die um Bolzen f drehbar gelagert sind. Der Bolzen f liegt in den Löchern I des Bügels o. An' dem langen Teile der Schenkel ist eine keilförmige Aussparung c für den an sich bekannten Stangenkeil b ausgenommen. DerAs can be seen from the drawing, the pliers consist of two legs Ct 1 and Ct 2 , which are rotatably mounted about bolts f. The bolt f lies in the holes I of the bracket o. A wedge-shaped recess c for the rod wedge b known per se is excluded on the long part of the legs. Of the
1S Stangenkeil b selbst wird im Ruhezustande der Zange (Fig. 2) durch die Druckfeder d gegen den Drehbolzen / geschoben und ermöglicht den Zugfedern e dadurch die Zange zu öffnen. Der Handhebel u, der in l„ drehbar gelagert ist und seinen andern Befestigungspunkt b im Punkte η des Stangenkeiles hat, bezweckt, die Zange durch Vor- bzw. Zurückschieben des Stangenkeiles b zu schließen (Fig. 1) bzw. zu öffnen. Die kürzeren Zangenteile k, die.' den Draht fassen, sind schnabelförmig ausgebildet, um möglichst weit zwischen die rotierenden Matrizenwalzen reingeschoben werden zu können. Zur größeren Sicherheit sind sie noch mit zwei gehärteten und ebenfalls geriffelten Schrauben j versehen, die sich mit erhöhter Greifkraft in das Material einkrallen. 1 S rod wedge b itself is pushed against the pivot pin / by the compression spring d when the pliers are at rest (Fig. 2), thereby enabling the tension springs e to open the pliers. The hand lever u, which is rotatably mounted in 1 and has its other fastening point b at point η of the rod wedge, aims to close or open the pliers by pushing the rod wedge b forwards or backwards (FIG. 1). The shorter pliers parts k that . ' grip the wire are beak-shaped so that they can be pushed as far as possible between the rotating die rollers. For greater security, they are also provided with two hardened and also fluted screws j , which claw into the material with increased gripping force.
Beim Gebrauche wird die geöffnete Zange möglichst weit zwischen die Walzen i geschoben, der Hebel u wird umgelegt, wodurch die Zange sich schließt und den zu ziehenden Stab fest erfaßt. Der Haken des Ziehwagens wird in die Kette des Ziehwagens eingehängt. In diesem Augenblick wird zuerst am Stangenkeil b gezogen, wodurch sich die Zange so lange immer kräftiger schließt, bis die Wirkung der Zugkraft der Ziehbank 'und die-Übersetzung des verlängerten Hebelarmes χ zusammen die Höchstklemmkraft der' Zange erreicht haben. Ist der Stab fertig gezogen, und die Zugkraft der Ziehbank hat aufgehört zu wirken, so drückt die Druckfeder d den Stangenkeil zurück und die Zugfedern e öffnen die Zange, wodurch der fertig gezogene Stab selbsttätig freigegeben wird. r During use, the open pliers are pushed as far as possible between the rollers i , the lever u is turned over, whereby the pliers closes and firmly grips the rod to be pulled. The hook of the pulling trolley is hooked into the chain of the pulling trolley. At this moment, the rod wedge b is first pulled, causing the pliers to close more and more forcefully until the effect of the pulling force of the drawbench and the translation of the extended lever arm χ together have reached the maximum clamping force of the 'pliers. When the rod is completely drawn and the tensile force of the draw bench has ceased to act, the compression spring d pushes the rod wedge back and the tension springs e open the pliers, whereby the completely drawn rod is automatically released. r
