  Stanzmesser zum Ausstanzen von Lederscheiben, Dichtungsringen u. dgl. 
 EMI1.1 
 förmige Stanzstücke von verschiedenen Abmessungen aus Leder, Klingerit od. dgl. auszustanzen. 



   Die Fig. 1 der beigegebenen Zeichnung zeigt den Messerträger, die Fig. 2 die in den Träger einzusetzenden Ringmesser im Schnitt. Der Messerträger   k   besitzt an seiner ebenen Unterseite eine Anzahl von kreisförmigen Nuten a, b,   c, cl,   und eine zentrale zylindrische Bohrung e, in welche die passenden ringförmigen Fortsätze m, n, o, p, der Stanzmesser eingeführt werden können. Um nun die eingesetzten Messer in ihrer Lage im Messerhalter festzuhalten, sind die Nuten und die Messeransätze mit gegenüberliegenden halbkreisförmigen Nuten    < y, , t   bzw. r, s, t,   M,   versehen, deren konvexe Seiten gegeneinander gestellt sind, so dass ein voller Kreisquerschnitt gebildet wird, der sich in dem ganzen Umfang herum erstreckt.

   In diese so gebildeten kreisförmigen Nuten werden ringförmige Federn eingelegt, die ein Verschieben der Messer verhindern sollen. Ist nun der Dichtungsring ausgestanzt, so bleibt er in den meisten Fällen im Stanzmesser haften. Um ihn nun leicht aus dem Messer zu entfernen, sind über jeder Ringnut Löcher v angeordnet, durch die man mit Hilfe eines eisernen Dornes das ausgestanzte Stück leicht aus dem Messer ausstossen kann. 



   Durch Auswahl entsprechender Ringmesserformen und Grössen ist es möglich, sowohl kreisförmige, als auch ringförmige   Stanzstücke   verschiedener Grösse herzustellen.

1. Stanzmesser zum Ausstanzen von Lederscheiben, Dichtungsringen u. dgl., dadurch gekennzeichnet, dass in   einem Messerträger (E)   an dessen Unterseite eine Mehrzahl von ringförmigen Nuten

  Punch knife for punching leather discs, sealing rings, etc. like
 EMI1.1
 shaped punched pieces of various dimensions from leather, klingerite or the like.



   Fig. 1 of the accompanying drawing shows the knife carrier, Fig. 2 shows the ring knife to be inserted into the carrier in section. The knife carrier k has on its flat underside a number of circular grooves a, b, c, cl, and a central cylindrical bore e, into which the matching annular extensions m, n, o, p, of the punching knife can be inserted. In order to hold the knives used in their position in the knife holder, the grooves and the knife attachments are provided with opposite semicircular grooves <y,, t or r, s, t, M, whose convex sides are placed against one another so that a full Circular cross-section is formed, which extends around the entire circumference.

   In these circular grooves formed in this way, annular springs are inserted, which are intended to prevent the knife from shifting. If the sealing ring is now punched out, it will in most cases stick to the punching knife. In order to easily remove it from the knife, holes v are arranged above each ring groove through which the punched piece can easily be ejected from the knife with the help of an iron mandrel.



   By selecting the appropriate ring knife shapes and sizes, it is possible to produce both circular and ring-shaped punched pieces of various sizes.
