Description

Die Greifbacken bei Zugwagen von Rohr- und Stang@enziehbänken werden üblicherweise als flache oder konkave, gezahnte Backen ausgeführt, die mit einem 'Schwalbenschwanzansatz in Ausn@ehmungen der Backenhalter gehalten werden.The gripping jaws on towing vehicles are used for pipe and bar drawing benches usually designed as flat or concave, toothed jaws with a '' The dovetail should be held in the recesses of the jaw holder.

Die Erfindung zeigt einen Backenhalter, in dem vier gehärtete Rundbacken vorgesehen sind, die mit einem zylindrischen oder schraubenförmigen Profil versehen und in parallel zur Vorschubrichtung liegenden Bohrungen des Backenhalters angeordnet sind, durch deren zur Ziehmitte hin weisende Durchbrüche sie in den Greifraum hineinragen. D@le runden Greifbacken liegen hierdurch nahe der Ziehmitte frei.The invention shows a jaw holder in which four hardened round jaws are provided which are provided with a cylindrical or helical profile and arranged in bores of the jaw holder lying parallel to the feed direction are, through whose openings pointing towards the center of the drawing they protrude into the gripping space. The round gripper jaws are thereby exposed near the center of the drawing.

In den Zeichnungen ist in Fig. i und z ein Ausführungsbeispiel, in Fig. 3 ein weiteres Ausführungsbeispiel des Erfindungsgegenstandeg dargestellt.In the drawings, in Fig. I and z, an embodiment in Fig. 3 shows a further embodiment of the subject matter of the invention.

In Fig. i und ä bedeuten a die Backenhalter. In die Backenhalter sind je zwei Löcher gebohrt, in denen die profiliierten Rundbacken. liegen. Diese Löcher sind nach der Ziehmitte freigeschnitten. so daß die Rundbacken b auf einem Teil ihres Umfanges frei liegen. Die Bohrungen der Backenhalber sind mit der gleichen Verzahnung versehen wie die Rundbacken selbst.In Fig. I and ä, a mean the jaw holder. In the jaw holders are Two holes are drilled each in which the profiled round jaws. lie. These holes are cut free after the center of the drawing. so that the round jaws b on one part their scope are free. The holes in the jaws are the same Toothed like the round jaws themselves.

Die Rundbacken besitzen an ihren Enden einen Innen- oder Außenvierkant c, so daß sie gedreht werden können, sobald sie abgenutzt sind.The round jaws have an inside or outside square at their ends c so that they can be rotated once they are worn out.

In Fig.3 ist ein weiteres Ausführungsbeispiel des Erfindungsgegenstandes im Grundriß dargestellt. Die profilierten Rundbacken e haben beiderseitig Zapfen d, die in kleinen Bohrungen der Backenhalber gelagert sind. Hierbei sind die Bohrungen in den Backenhaltern, die dem Außendurchmesser der Rundbacken entsprechen, glatt. Die Lagerbohrungen für den vorderen Zapfen e liegen jeweils in einer abnehmbaren Platte f, nach deren Entfernung die Rundbacken herausgenommen werden können.In Figure 3 is a further embodiment of the subject matter of the invention shown in plan. The profiled round jaws e have tenons on both sides d, which are stored in small holes in the jaws. Here are the holes in the jaw holders, which correspond to the outer diameter of the round jaws, smooth. The bearing bores for the front pin e are each located in a removable one Plate f, after which the round jaws can be removed.

Ein Vorteil dieser Backenform ist, daß die Rundbacken die Rohre oder Stangen an vier Punkten angreifen, so daß ein sehr sicheres Greifen auch der kürzesten Ziehenden möglich ist.An advantage of this jaw shape is that the round jaws the tubes or Attack rods at four points so that even the shortest can be gripped very securely Pulling is possible.

Dier Hauptvorteil ist der; daß nach Verschleiß der Zähne an den Greifstellen durch längere Benutzung die Backen so weitergedreht werden können, daß nicht abgenutzte Teile des Umfanges zum Greifen kommen. Auf diese Weise können die Rundbacken auf dem ganzen Umfang ausgenutzt werden.The main advantage is that; that after wear of the teeth at the gripping points after prolonged use the jaws can be turned so that they are not worn out Parts of the scope come within reach. This way the round jaws can open be used to the full extent.

Dazu kommt noch der Vorteil, daß die Herstellung der Rundbacken wesentlich einfacher ist als die der Flachbacken, da sie auf einer Drehbank durchgeführt werden kann. -Sie erfordert auch weniger hochwertiges Material.There is also the advantage that the manufacture of the round jaws is essential is easier than that of the flat jaws, as they are carried out on a lathe can. -It also requires less high quality material.

Die vorgeschlagenen Greifbacken können bei allen Maschinen angewandt werden, in denen Rund-und Vierkantkörper unter großem Arbeitsaufwand gezogen oder vorgeschoben werden müssen.The proposed gripper jaws can be used with all machines in which round and square bodies are drawn with great effort or must be advanced.
