PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Messer zum Ausstanzen von Leder oder anderen weichen Stoffen, das in bekannter Weise aus einem an einem inneren, den Stanzdruck aufnehmenden Kern befestigten biegsamen Stahlband besteht. Die Bauart des Messers ist so verbessert, daß die dünne Stahlschneide in zwei Metallrahmen mittels T-förmiger Stücke festgemacht ist, die durch die Löcher der Klinge gehen. Infolgedessen kann die Form der Stanze ohne besondere Hilfsmittel beliebig verändert werden. Der den Druck der Presse ausgleichende Rahmen ist innerhalb der Klinge angeordnet, also auf der Seite, an der das Schneiden am regelmäßigsten sein muß, so daß das Stanzen erfolgt, ohne daß Falten im Werkstück gebildet werden. Auch kann das Messer sehr weit abgeschliffen werden.The invention relates to a knife for punching leather or other soft materials, which consists in a known manner of a flexible steel band attached to an inner core that absorbs the punching pressure. The design of the knife is improved so that the thin steel cutting edge is in two metal frames by means of T-shaped pieces that go through the holes in the blade. Consequently the shape of the punch can be changed as required without special tools. The one who balances the pressure of the press The frame is arranged inside the blade, i.e. on the side on which the cutting takes place must be regular so that punching takes place without wrinkles being formed in the workpiece will. The knife can also be sharpened very far.
In der Zeichnung ist:In the drawing is:
Fig. ι eine Draufsicht auf das Stanzmesser, Fig. 2 eine Seitenansicht, teilweise im Schnitt, Fig. 3 eine Ansicht in größerem Maßstabe des linken Teiles der Fig. 2.Fig. Ι a plan view of the punch knife, Fig. 2 is a side view, partially in section, FIG. 3 is a view on a larger scale of the left part of FIG. 2.
Das Messer 1 ist an dem aus zwei Metallrahmen 2 bestehenden Kern mittels schmaler T-Stücke 3 befestigt, die durch Öffnungen des Messers hindurchgesteckt sind, so daß ihre Schenkel zwischen den Metallrahmen 2 liegen. Die T-Stücke 3 werden durch Niete 4 in den Metallrahmen befestigt.The knife 1 is on the core consisting of two metal frames 2 by means of narrower T-pieces 3 attached, which are inserted through openings of the knife so that their Legs lie between the metal frame 2. The tees 3 are riveted into the Metal frame attached.
Die Metallrahmen 2 sind ausgeschnitten, so daß ihre Ränder ungefähr 1 cm über den Rand des auszustanzenden Stückes nach einwärts reichen. Es ist auf diese Weise möglich, das ausgestanzte Stück mit der Hand auszustoßen, falls es im Messer sitzen bleiben sollte.The metal frames 2 are cut out so that their edges about 1 cm above the Reach inward at the edge of the piece to be punched out. It is possible in this way to push out the punched piece by hand if it should stay in the knife.
Das Messer ' kann in bekannter Weise so eingerichtet sein, daß es durch einfaches Umdrehen zum Stanzen von rechtsseitigen oder linksseitigen Stücken verwendet werden kann.The knife 'can be set up in a known manner so that it is simply turned around Can be used to punch right-sided or left-sided pieces.
