    Vorrichtung zum Ziehen und gleichzeitigen Reinschneiden der Kanten von Blechbüchsen, Büchsendeckeln und dgl.   
 EMI1.1 
 die den Gegenstand der vorliegenden Erfindung bildende Vorrichtung wird die zeitversch wenderische Reinschneidungsarbeit vermieden und sowohl das Ziehen als auch das Reinschneiden in einer   und derselben   Operation ermöglicht. 



     Eine Ausführungsform der Erfindung   ist auf der   Zeichnung     veranschaulicht. Fig. J und r   sind Schnitte   durch eine derartige Vorrichtung für   die Herstellung von Blechbüchsen und zwar bei Stellung der verschiedenen Teile vor dem Arbeitsschlag und nach demselben. Fig. 3 zeigt einen Teil der Vorrichtung in grösserem Massstabe. 



   1 ist die Form. über welche die Büchse geprsst oder gezogen wird. Diese Form hat bei eine Kante oder einen Absatz, welcher dem Rand der fertigen Büchse oder des   Büchsendeckels   
 EMI1.2 
 das Blechstück an dem   Messer J zugeschnitten worden   ist und während der   Presskopf dasselbe   gegen   die   Form 1 andrückt, die Kanten des Bleches längs der Seitenfläche der Form 1 hinab und schneidet zuletzt den änsseren Teil der Blechkante an dem Absatz   2 der Form 1 rein.   Um das Herabpressen des Bleches auf die Form 1 zu erleichtern, wird die Unterkante des Stempels 6   vorzugsweise abgerundet. Für das Abschneiden gegen den Absatz   ist ein entsprechender Absatz 7 an dem Stempel 6 (Fig. 3) vorgesehen.

   Bei der Anwendung eines derartigen Absatzes 7 wird jede Gefahr für Festklemmung des Bleches zwischen dem Stempel 6 und der Form 1 vollständig   ausgeschlossen. *  
Die gegeneinander gekehten Flächen der Form 1 und des   Presskopfes J können   mit Gravierungen zum Einpressen von Ornamenten, Linien u. dgl. in den Boden oder den Deckel der Büchse versehen sein. Vorzugsweise werden zwischen dem Presskopf 5 und dem Kopf des Stempels 6 Federn eingelegt, welche aber der Einfachheit halber auf der Zeichnung fortgelassen sind.

    Device for pulling and simultaneously cutting the edges of tin cans, can lids and the like.
 EMI1.1
 the device forming the subject of the present invention avoids the time wasting clipping work and enables both pulling and clipping in one and the same operation.



     An embodiment of the invention is illustrated on the drawing. Fig. J and r are sections through such a device for the production of sheet metal cans with the position of the various parts before and after the work stroke. Fig. 3 shows part of the device on a larger scale.



   1 is the shape. over which the rifle is pressed or pulled. This shape has an edge or a shoulder, which is the edge of the finished can or the can cover
 EMI1.2
 the piece of sheet metal has been cut on the knife J and while the press head presses the same against the form 1, the edges of the sheet along the side surface of the form 1 and finally cuts the outer part of the sheet metal edge at the shoulder 2 of the form 1. In order to make it easier to press the sheet down onto the mold 1, the lower edge of the punch 6 is preferably rounded. A corresponding paragraph 7 is provided on the punch 6 (FIG. 3) for cutting against the paragraph.

   When such a paragraph 7 is used, any risk of the sheet jamming between the punch 6 and the mold 1 is completely excluded. *
The mutually turned surfaces of the form 1 and the press head J can be engraved for pressing in ornaments, lines and the like. Like. Be provided in the bottom or the lid of the box. Springs are preferably inserted between the pressing head 5 and the head of the punch 6, but these have been omitted from the drawing for the sake of simplicity.
 EMI1.3
 in sheet metal manufacturing, not only when the pure cut edge should be straight. but also if it should have any other shape.

** WARNING ** End of DESC field may overlap beginning of CLMS **.
