Description

Die Erfindung bezieht sich auf eine Haltevorrichtung für Stanzmesser an einer Stanzmaschine, insbesondere Karrenbalken­stanze oder Brückentellerstanze, bei welcher der Druckfuß mit dem daran angebrachten Stanzmesser drehbar ist.The invention relates to a holding device for punching knives on a punching machine, in particular trolley punch or bridge plate punch, in which the pressure foot with the punching knife attached to it can be rotated.

Die Stanzmesser einer Stanzmaschine werden üblicherweise auf eine Tragplatte geschraubt und diese je nach Ausführung ent­weder in Winkelschienen oder Schwalbenschwanzschienen am Stanzkopf, welcher die Stanzbewegung ausführt, eingeschoben. Das Stanzmesser muß insbesondere bei programmierten Stanzen eine genau bestimmte Lage zum Mittelpunkt des Druckfußes des Stanzkopfes haben. Wird ein Stanzmesser an einer sogenannten Karrenbalkenstanze oder Brückentellerstanze eingesetzt, bei welcher der Druckfuß auch gedreht wird, muß das Stanzmesser genau zentrisch zur Drehachse montiert sein. Die genaue mittige bzw. zentrische Lage des Stanzmessers kann bei her­kömmlichen Stanzmaschinen nur schwierig eingerichtet werden.The punching knives of a punching machine are usually screwed onto a support plate and, depending on the design, these are either inserted into angle rails or dovetail rails on the punching head which carries out the punching movement. The punching knife must have a precisely defined position to the center of the pressure foot of the punching head, especially in the case of programmed punching. If a punch knife is used on a so-called cart beam punch or bridge plate punch, in which the pressure foot is also rotated, the punch knife must be mounted exactly in the center of the axis of rotation. The exact central or central position of the punching knife is difficult to set up in conventional punching machines.

Aufgabe der vorliegenden Erfindung ist es, eine Haltevor­richtung für Stanzmesser der gattungsgemäßen Art vorzuschlagen bei welcher eine einfache mittige bzw, zentrische Einrichtung des Stanzmessers möglich ist.The object of the present invention is to propose a holding device for punching knives of the generic type in which a simple central or central arrangement of the punching knife is possible.

Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß am Druckfuß eine Magnetspannplatte angebracht ist, welche auf der dem Stanzmesser zugewandten Anlagefläche wenigstens zwei Leisten oder Nuten aufweist, welche sich oder deren gedachte Verlängerungen sich in der Mittelachse bzw. Drehachse des Druckfußes schneiden, wobei das jeweilige Stanz­ messer auf seiner der Magnetspannplatte zugekehrten Anlage­fläche zu den Leisten oder Nuten passende Nuten oder Stifte aufweist. Auf diese Weise läßt sich das Stanzmesser jederzeit problemlos mittig bzw. zentrisch am Druckfuß festlegen. Da­durch, daß die Magnetspannplatte sich in der Mittelachse bzw. Drehachse einander kreuzende Leisten oder Nuten aufweisen, über bzw. in welche bei Montage des Stanzmessers entsprechende Nuten bzw. Stifte greifen können, wird eine zwangsläufige Zentrierung erreicht. Auch andere Kombinationen von Vor­sprüngen und Vertiefungen sind brauchbar.This object is essentially achieved in that a magnetic chuck is attached to the pressure foot, which has at least two ledges or grooves on the contact surface facing the punching knife, which or their imaginary extensions intersect in the central axis or axis of rotation of the pressure foot, the respective punch knife on its contact surface facing the magnetic chuck has grooves or pins matching the strips or grooves. In this way, the punching knife can be fixed in the middle or center of the pressure foot at any time. Due to the fact that the magnetic clamping plate has strips or grooves which cross each other in the central axis or axis of rotation and over or into which corresponding grooves or pins can engage when the punching knife is mounted, an inevitable centering is achieved. Other combinations of protrusions and recesses can also be used.

Die Leisten oder Nuten an der Magnetspannplatte verlaufen lassen vorzugsweise senkrecht zueinander.The strips or grooves on the magnetic chuck preferably run perpendicular to one another.

In der Regel reichen zwei, z.B. senkrecht zueinander verlau­fende Leisten oder Nuten an der Magnetspannplatte aus. Vor­zugsweise sind jedoch vier im rechten Winkel zueinander ver­laufende Liesten oder Nuten an der Magnetspannplatte vorge­sehen.Usually two, e.g. strips or grooves running perpendicular to each other on the magnetic chuck. However, four Liesten or grooves running at right angles to each other are preferably provided on the magnetic chuck.

Bei einer besonderen Ausgestaltung des Erfindungsgedankens einden die Leisten oder Nuten an der Magnetspannplatte im Abstand vor der Mittelachse oder Drehachse des Druckfußes und verlaufen bis zum Außenrand der Magnetspannplatte. Auf diese Weise sind die Leisten oder Nuten nur dort vorgesehen, wo sie zur Zentrierung des angesetzten Schneidmessers erforderlich sind, ohne das die Gefahr besteht, daß sich das Schneidmesser gegenüber der Magnetspannplatte verdreht.In a special embodiment of the inventive concept, the strips or grooves on the magnetic chuck are spaced apart from the central axis or axis of rotation of the pressure foot and extend to the outer edge of the magnetic chuck. In this way, the strips or grooves are only provided where they are required for centering the attached cutting knife, without the risk that the cutting knife will rotate relative to the magnetic chuck.

Der Stanzkopf von Fig. 1, der beispielsweise für eine nicht dargestellte Brückentellerstanze bestimmt ist, weist eine Mag­netspannplatte 1 auf, welche an einen Druckfuß 2 des Stanz­kopfes angeschraubt ist. Die Funktion einer solchen Brücken­tellerstanze ergibt sich beispielsweise aus der DE-A-2 827 138. Auf der unteren Anlagefläche der Magnetspannplatte 1 sind Leisten 3 vorgesehen, welche im Bezug auf die Mittelachse bzw. die Drehachse des Druckfußes 2 kreuzweise, und zwar wie sich aus Fig. 2 ergibt, im rechten Winkel zueinander verlaufen. In dem dargestellten Fall sind vier Leisten 3 vorgesehen, welche vor der Mittelachse bzw. Drehachse des Druckfußes 2 enden und bis zum Außenrand der Magnetspannplatte 1 verlaufen, wie insbesondere aus Fig. 2 ersichtlich ist. In den Stanzmessern 4 (Fig. 3) bzw. 5 (Fig. 4) sind Nuten 4ʹ bzw. 5ʹ eingearbeitet, welche mit geringem Spiel zu den Leisten 3 der Magnetspann­platte 1 passen. Statt der Leisten 3 kann die Magnetspann­platte 1 auch mit Nuten 6 versehen sein, wie Fig. 5 veran­schaulicht. Die Stanzmesser 4 bzw. 5 haben dann dazu passende Stifte 7.The punching head of FIG. 1, which is intended, for example, for a bridge plate punch, not shown, has a magnetic chuck 1 which is screwed onto a pressure foot 2 of the punching head. The function of such a bridge plate punch results, for example, from DE-A-2 827 138. Bars 3 are provided on the lower contact surface of the magnetic chuck 1, which crosswise with respect to the central axis or the axis of rotation of the pressure foot 2, as is evident from Fig. 2 shows to run at right angles to each other. In the illustrated case, four strips 3 are provided, which end in front of the central axis or axis of rotation of the pressure foot 2 and extend to the outer edge of the magnetic chuck 1, as can be seen in particular from FIG. 2. In the punching knives 4 (FIG. 3) and 5 (FIG. 4) grooves 4ʹ and 5ʹ are incorporated, which fit with little play to the strips 3 of the magnetic chuck 1. Instead of the strips 3, the magnetic chuck 1 can also be provided with grooves 6, as illustrated in FIG. 5. The punch knives 4 and 5 then have matching pins 7.

Die Stanzmesser 4,5 lassen sich auf diese Weise zentrisch bzw. in einer vorbestimmten Lage an der Magnetspannplatte 1 an­bringen.The punching knives 4, 5 can be attached to the magnetic chuck 1 centrally or in a predetermined position.
