Das Hauptpatent 954 774 betrifft eine in einem Schubschlitten angeordnete Einstoßvorrichtung für Zieh-, insbesondere Stangenziehbänke.The main patent 954 774 relates to a pusher arranged in a push carriage for Drawing benches, in particular bar drawing benches.

Diese Vorrichtung weist zum selbsttätigen und sicheren Festklemmen des einzustoßenden Ziehguts in die Ziehmatrize und zur Erzielung eines großen Arbeitsbereichs ein Doppelkeilsystem auf. Diese Anordnung reicht jedoch noch nicht dazu aus, ohne einen Wechsel der Keil- bzw. Klemmbacken einen übergroßen Arbeitsbereich von beispielsweise 16 bis 65 mm Durchmesser zu überbrücken.This device is designed to automatically and safely clamp the drawn material to be pushed in in the drawing die and a double wedge system to achieve a large working area. This arrangement However, it is not sufficient to create an oversized one without changing the wedge or clamping jaws To bridge working areas of 16 to 65 mm in diameter, for example.

Gegenstand der Erfindung ist eine Einstoßvorrichtung, die mittels einer Stellvorrichtung auf einen Werkstückdurchmesserbereich einstellbar ist, der allein durch das Verschieben der innenliegenden und das einzustoßende Werkstück umfassenden Keilbacken bestreichbar ist. Mit Hilfe dieser Anordnung wird ein übergroßer Klemm- bzw. Arbeitsbereich der Einstoßvorrichtung ohne das sonst erforderliche Wechseln der Keilbacken erzielt.The invention relates to a push-in device, which by means of an adjusting device on a Workpiece diameter range is adjustable, which is achieved solely by moving the internal and the wedge jaws comprising the workpiece to be pushed in can be brushed. With the help of this arrangement becomes an oversized clamping or working area of the pusher without the otherwise required Changing the wedge jaws achieved.

Der Aufbau und die Wirkungsweise der erfindungsgemäßen Einstoßvorrichtung ergeben sich aus folgenden Ausführungen:The structure and the mode of operation of the pusher device according to the invention result from the following Executions:

Nach der Zeichnung besteht die Einstoßvorrichtung aus dem Schubschlitten 1, in dem ebenfalls ein Mehrfachkeilsystem unter Zwischenlage von Rollen angeordnet ist. An den geraden Innenwänden des Schubschlittens 1 liegen die über Stellschrauben 2 in Pfeilrichtung hin- und herbewegbaren Stellkeile 3, welche die in der Ziehachse durch die Stollen 4 festgelegten Zwischenkeile 5 zur Anpassung der Keilbacken 6 an das Ziehgut 7 quer zur Einstoßrichtung bewegen. Die Keilbacken 6 laufen unter Zwischenlage der Rollen 8 auf den Zwischenkeilen 5; zwischen die Stellkeile 3 und die Zwischenkeile 5 können ebenfalls Rollen 9 eingelegt werden.According to the drawing, the pushing device consists of the push slide 1, in which a multiple wedge system is also arranged with the interposition of rollers. To the straight inner walls of the thrust carriage 1, the back adjusting screws 2 in the direction of arrow reciprocable actuating wedges 3 which 5 scroll set out in the drawing axis through the tunnels 4 intermediate wedges to adapt the wedge jaws 6 to the drawn material 7 transverse to Einstoßrichtung lie. The wedge jaws 6 run with the interposition of the rollers 8 on the intermediate wedges 5; Rollers 9 can also be inserted between the adjusting wedges 3 and the intermediate wedges 5.

Durch Hin- und Herbewegen der Stellkeile 3 werden gleichzeitig die zwischen den Stollen 4 axial gehaltenen Zwischenkeile 5 und damit auch die auf Rollen 8 gelagerten Keilbacken 6 senkrecht zur Ziehachse bewegt und dadurch auf einen bestimmten Werkstückdurchmesserbereich eingestellt. Letzterer ist durch das Verschieben der Keilbacken 6 in der Ziehachse bestreichbar und dient zum Festklemmen des Werkstückes 7 zu Beginn des Einstoßvorganges.By moving the adjusting wedges 3 back and forth, the intermediate wedges 5 held axially between the cleats 4 and thus also the wedge jaws 6 mounted on rollers 8 are moved perpendicular to the pulling axis and thereby adjusted to a specific workpiece diameter range. The latter can be brushed by moving the wedge jaws 6 in the pulling axis and is used to clamp the workpiece 7 at the beginning of the pushing-in process.

Der Fortschritt der Erfindung besteht darin, daß eine Einstoßvorrichtung mit vorstehend beschriebener Anordnung der eingebauten Klemm- und Stell-Einstoßvomchüing für ZiehbänkeThe advance of the invention is that a pusher with the above Arrangement of the built-in clamping and adjusting push mechanism for draw benches

elemente einen noch größeren Arbeitsbereich aufweist, als mit den bisher bekannten Mitteln ermöglicht wurde. Der betriebliche Vorteil beruht ferner auf dem Fortfall der zur Anpassung an geänderte Werkstückdurchmesser sonst notwendigen Keilbacken (Klemmbacken) sowie auf dem Fortfall langer Umbauzeiten der Einstoßvorrichtung bei Änderung des Arbeitsprogramms. elements has an even larger work area than is possible with the previously known means became. The operational advantage is also based on the elimination of the need to adapt to changed workpiece diameters otherwise necessary wedge jaws (clamping jaws) as well as the elimination of long conversion times the pusher when changing the work program.

Claims (1)

Patentanspruch:Claim: Einstoßvorrichtung für Ziehbänke zum Spannen von Werkstücken innerhalb eines großen Durchmesserbereichs ohne Auswechseln der Keilbacken, bei der sich das im Schubschlitten parallel zur Ziehachse verschieblich sowie insbesondere rollengelagerte Keilbackenpaar mit sich in Ziehrichtung öffnender Keilform über ein gleichfalls gegenüber dem Schlitten axial verschiebliches Stützkeilsystem am Schlitten abstützt, nach Patent 954 774, dadurch gekennzeichnet, daß die Axiallage der Stützkeile (3) gegenüber dem Schubschlitten (1) durch Stellschrauben (2) einstellbar ist und daß sich zwischen den Stützkeilen (3) und den Klemmbacken (6) rollengelagerte (8, 9) Zwischenkeile (5) befinden, die durch Stollen (4) des Schlittens (1) axial gehalten, d. h. durch Verstellen der Stützkeile (3) nur senkrecht zur Ziehachse bewegbar sind.Push-in device for draw benches for clamping workpieces within a large diameter range without replacing the wedge jaws, in which the pair of wedge jaws, which are displaceable in the push slide parallel to the drawing axis and in particular roller-mounted, with a wedge shape that opens in the drawing direction, is supported on the slide via a support wedge system that is also axially displaceable with respect to the slide Patent 954 774, characterized in that the axial position of the support wedges (3) with respect to the thrust slide (1) can be adjusted by means of adjusting screws (2) and that between the support wedges (3) and the clamping jaws (6) there are intermediate wedges (8, 9) mounted on roller bearings (5) are located, which are held axially by cleats (4) of the carriage (1) , ie can only be moved perpendicular to the pulling axis by adjusting the support wedges (3).
