KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Mittelst der neuen Maschine soll jeder nicht unumgänglich erforderliche Abfall vermieden und daher sichere Einstellung des Vorschubes des Blechstreifens erzielt werden, sowie Trennung der Abfallstreifen, um daduich die Blechverschiebung an der Einstellvorrichtung vorbei zu erleichtern.With the new machine, any waste that is not absolutely necessary should be avoided and therefore secure adjustment of the feed of the sheet metal strip can be achieved, as well as separation the scrap strip to get the sheet metal shifting around it to facilitate past the adjustment device. Fig. ι ist eine Vorderansicht der Maschine, Fig. 2 eine Seitenansicht, Fig. 3 ein Horizontalschnitt nach III—III, Fig. 4 ein Horizontalschnitt nach IV-IV der Fig. 2; Fig. 5 zeigt den Einstelloder Schnittstahl, seitlich gesehen; Fig. 6 bis 8 zeigen das Product im ersten -und zweiten Stadium, sowie den erhaltenen Abfall.Fig. 1 is a front view of the machine, Fig. 2 is a side view, Fig. 3 is a horizontal section according to III-III, FIG. 4 shows a horizontal section according to IV-IV of FIG. 2; Fig. 5 shows the setting or Cut steel, seen from the side; 6 to 8 show the product in the first and second Stage, as well as the received waste. Die Maschine ist im wesentlichen den bekannten Durchschnitten und Stanzwerken zum Ausstofsen und Formen ähnlich; es sollen nur die neuen Theile derselben und deren Thätigkeit beschrieben werden. Das Blech wird in Streifen von unmerklich gröfserer Breite, als der Lochstempeldurchmesser beträgt, geschnitten , und diese Streifen werden' auf die winkelförmige Vorlage O gelegt, welche mit ihrem hinteren inneren Rand genau dem Lochstempel entsprechend eingestellt ist. Der Blechstreifen wird von Hand nach jedem Stempelhub vorgeschoben und der Blechvorschub genau durch ein am Gestell A der Maschine einstellbar befestigtes Messer P bestimmt, welches mit der Schneidkante dicht an dem Rand der Lochmatrize steht. Beim Vorschieben wird das Blech bis gegen die Schneidkante gestofsen, während nach dem Ausstofsen durch einen etwas stärkeren Druck die geringe verbliebene Blechbreite von Loch zu Loch leicht von der Schneidkante durchschnitten wird, so dafs der Abfall, wie Fig. 8 zeigt, in zwei Streifen aus der Maschine kommt. Durch die neue Vorrichtung, welche ein Ausweichen vor dem Blech nicht bedingt, dagegen letzteres, durchschneidet, damit es der Vorrichtung ausweichen kann, ist der Abfall auf das geringste Mafs gebracht worden.The machine is essentially similar to the known cutting machines and punching machines for shaping and shaping; only the new parts of it and their activity will be described. The sheet metal is cut into strips of imperceptibly larger width than the punch diameter, and these strips are placed on the angular template O , which is set with its rear inner edge exactly to match the punch. The sheet metal strip is advanced by hand after each punch stroke and the sheet metal advance is precisely determined by a knife P which is adjustably attached to the frame A of the machine and whose cutting edge is close to the edge of the perforated die. When it is pushed forward, the sheet metal is pushed up to the cutting edge, while after the outside, by applying somewhat stronger pressure, the small remaining sheet width is easily cut through by the cutting edge from hole to hole, so that the waste, as Fig. 8 shows, in two strips the machine comes. With the new device, which does not require evasion in front of the sheet metal, but cuts through the latter so that it can evade the device, the waste has been reduced to a minimum. Patent-Anspruch:Patent claim: Maschine zum Ausstofsen von Blechscheiben für Knopfobertheiie, gekennzeichnet durch ein hinter der Matrize (am Gestell hebelarmartig) angeordnetes Messer (P), durch welches vor dem Ausstofsen der Scheibe der Vorschub des Blechstreifens begrenzt und nach dem Ausstofsen unter geringem Druck gegen die Schneide das vor dem Loch verbliebene Material durchschnitten wird.Machine for the outside of sheet metal disks for button tops, characterized by a knife (P ) arranged behind the die (on the frame like a lever arm), by which the advance of the sheet metal strip is limited in front of the outside of the disk and after the outside under slight pressure against the cutting edge the before the Any material remaining in the hole is cut through.
