Description

Die Erfindung bezieht sich auf ein vereinigtes Schnitt- und Prägewerkzeug, welches besonders ge-.eignet ist zur Verwendung an Pressen mit großem, unverstellbarem Hub, bei denen sich Führungs-und Blockschnitte nicht ohne weiteres verwenden lassen.The invention relates to a combined cutting and embossing tool, which is particularly suitable for use on presses with large, unadjustable Hubs where guide and block cuts cannot easily be used.

Die Erfindung besteht darin, daß der Prägestempel an .dem bzw. den Schnittstempeln des Werkzeuges geführt ist und sich an diesem mittels eines Gummikissens abstützt, so daß er in :der Ruhelage mit seiner Unterkante etwas über die Arbeitskanten der Schnittstempel hinausragt.The invention consists in that the die on .dem or the Cutting stamping the tool is performed and attached to it by means of a rubber cushion supported so that he in: the rest position with his lower edge something over the working edges the cutting punch protrudes.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht. Es zeigt Abb. i einen Längsschnitt durch den Stempel, Abb. 2 einen Längsschnitt durch die Matrize des Werkzeuges, Abb. 3 einen Querschnitt und Abb. 4 eine Teilansicht des herzustellenden Werkstückes.An exemplary embodiment of the invention is illustrated in the drawing. It shows Fig. I a longitudinal section through the stamp, Fig. 2 a longitudinal section through the die of the tool, Fig. 3 is a cross section and Fig. 4 is a partial view of the workpiece to be produced.

In dem zur Herstellung der Umrisse des. Werkstückes 5 dienenden Schnittstempel 6, welcher gleichzeitig auch die auswechselbaren Lochstempel 7, 8, 9 zur Herstellung der Löcher io, i i des Werkstückes trägt, ist .der Prägestempel 12 zur Herstellung der Sicke 13 des Werkstückes längs verschieblich geführt. Der Prägestempel stützt sich gegen ein innerhalb des Schnittstempels 6 angeordnetes Gummikissen 14, wobei dieses Gummikissen durch einen Absatz 15 an dem Lochstempel 9 unter .einer gewissen Vorspannung gehalten wird. Der Absatz 15 ist in einer solchen Höhe angeordnet, daß der Prägestempel 12 in der Ruhelage mit seiner Unterkante etwas über die Arbeitskanten 16 des Schnittstempels 6 hinausragt.In the cutting punch used to produce the outlines of the workpiece 5 6, which at the same time also the interchangeable punches 7, 8, 9 for the production the holes io, i i of the workpiece is .der die 12 for production the bead 13 of the workpiece is guided in a longitudinally displaceable manner. The die supports against a rubber cushion 14 arranged inside the cutting die 6, wherein this rubber cushion through a paragraph 15 on the punch 9 under .einer certain Bias is held. The paragraph 15 is arranged at such a height that the die 12 in the rest position with its lower edge slightly above the working edges 16 of the cutting punch 6 protrudes.

Beim Abwärtshub der Presse setzt also zunächst der Prägestempel 12 auf den auf der Matrize 17 liegenden Blechzuschnitt auf, um in diesen die Sicke 13 einzuprägen und ihn für die folgenden Schnittvorgänge unverrückbar auf der Matrize festzuhalten.During the downward stroke of the press, the die 12 is initially set on the sheet metal blank lying on the die 17 in order to insert the bead into it 13 and imprint it immovably on the die for the following cutting processes to hold on.

Erst dann erfolgt beim weiteren Niedergang der Presse das Ausschneiden der Umrisse des Werkstückes 5 mittels des Stempels 6 und darauf das Ausstanzen der Löcher io, i i mittels der Stempel 7, ä, 9, wobei das Gummikissen 14 mehr und mehr federnd zusammengedrückt wird. Um dieses Zusammendrücken des Gummikissens zu ermöglichen, ist innerhalb des Schnittstempels 6 ein ringförmiger Ausweichraum i8 um das Gummikissen herum angeordnet, in den hinein das Gummikissen .beim Zusammendrücken ausweicht und dabei die in dem Ausweichraum befindliche Luft zusammenpreßt. Beim darauffolgenden Aufwärtshub der Presse wirkt der federnde Prägestempel außerdem als Auswerfl-r.Only then is it cut out when the press goes down further the outline of the workpiece 5 by means of the punch 6 and then the punching out of the Holes io, i i by means of the punches 7, ä, 9, the rubber pad 14 more and more is resiliently compressed. To enable this compression of the rubber cushion, is within the cutting punch 6 an annular escape space i8 around the rubber cushion arranged around it, into which the rubber cushion deflects when pressed together and thereby compresses the air located in the escape space. The next The resilient die also acts as an ejector on the upstroke of the press.
