Description
Die Erfindung bezieht sich auf eine Lochstanze zum Lochen von Trägerflanschen oder Platten. Es ist bekannt, mit Hilfe einer derartigen Stanze zwei Löcher gleichzeitig zu S stanzen. Ferner ist bei derartigen Einrichtungen vorgeschlagen worden, den Abstand der beiden Stempelträger zu ändern. Diese Abstandsänderung erfolgte bisher durch Verschieben der Stempelschäfte mit ihren Einspannvorrichtungen. Zu diesem Zweck waren besondere Querführungen der Einspannvorrichtungen im Werkzeugschlitten notwendig. Das Wesen der Erfindung liegt nun darin, daß die Stempel zu ihren Schäften exzentrisch angeordnet sind, und die Schäfte in den Haltern durch Drehung eingestellt und mittels Stellschrauben festgestellt werden können. Den bekannten Einrichtungen gegenüber wird die Einstelao lung wesentlich vereinfacht, da die Stempelhalter in ihrer Lage zum Schlitten stehen bleiben.The invention relates to a punch for punching support flanges or Plates. It is known to use such a punch to close two holes at the same time S punch. It has also been proposed in such devices, the distance of the two stamp carriers. This change in distance was previously carried out by Moving the punch shafts with their clamping devices. For this purpose there were special transverse guides for the clamping devices necessary in the tool slide. The essence of the invention now lies in the fact that the stamps too their shafts are arranged eccentrically, and the shafts in the holders by rotation can be set and fixed by means of adjusting screws. The well-known Compared to facilities, the setting is much simplified because the punch holder stop in their position in relation to the sled.
Die Erfindung ist in der Zeichnung beispielsweise dargestellt, und zwar zeigen:
Abb. ι und 3 senkrechte Schnitte durch den Stempelträger mit den Stempeln in verschiedenen
Stellungen;The invention is shown in the drawing, for example, namely show:
Fig. Ι and 3 vertical sections through the stamp carrier with the stamps in different positions;
Abb. 2 ist ein Querschnitt der Abb. 1;Fig. 2 is a cross section of Fig. 1;
Abb. 4 und 5 sind Draufsichten der Matrizen für die Stempel.Figures 4 and 5 are top views of the dies for the punches.
Mit I und m sind die Matrizen bezeichnet, welche in geeigneter Weise im Tisch einer Stanze befestigt sind. Der zu stanzende Träger wird auf die Matrizen Z und in gelegt. An dem unteren Ende des nicht dargestellten Werkzeugschlittens ist eine Hülse e befestigt, in der sich zwei Stempelschäfte f und g befinden, die in einer gewissen Entfernung voneinander angeordnet sind. I and m denote the dies which are suitably fastened in the table of a punch. The carrier to be punched is placed on the dies Z and in . At the lower end of the tool slide, not shown, a sleeve e is attached, in which two punch shafts f and g are located, which are arranged at a certain distance from one another.
Um die Entfernung der paarweis zu stanzenden Löcher zu verändern, sind die Stempel n, 0 exzentrisch zu den Stempelschäften /, g angeordnet. Letztere können durch eine Drehung eingestellt werden und unter Zuhilfenahme der Schrauben/» festgestellt werden, die in Längsschlitze q eingreifen, welche in die Stempelschäfte einander sich gegenüberliegend eingefräst sind.In order to change the distance between the holes to be punched in pairs, the punches n, 0 are arranged eccentrically to the punch shafts /, g . The latter can be adjusted by turning and fixed with the aid of the screws / »which engage in longitudinal slots q which are milled into the punch shafts opposite one another.
Die Abb. 1 zeigt die Stempel in einer gewissen Entfernung voneinander, während die Abb. 3 die Stempel nahe beieinander darstellt. Die Matrizenlöcher r und j liegen so in den Matrizen I und m, daß sie durch Umlegen der Matrizen in Übereinstimmung mit den Stempeln gebracht werden können.Fig. 1 shows the stamps at a certain distance from one another, while Fig. 3 shows the stamps close together. The die holes r and j lie in the dies I and m in such a way that they can be brought into conformity with the punches by turning the dies.
