H. VOELTZKOW in BERLIN. Verfahren und Vorrichtungen zur Hersteilung eckiger metallener Einfassungen.H. VOELTZKOW in BERLIN. Methods and devices for the production of angular metal frames.
Patentirt im Deutschen Reiche vom 27. Mai 1879 ab.Patented in the German Empire on May 27, 1879.
Die Ränder der Photographierahmen oder ähnlicher Gegenstände aus Carton, Leder, Holz, Alabaster, Glas oder anderem Material werden häufig mit metallenen Einfassungen versehen, die im wesentlichen einen Querschnitt haben, wie solcher aus Fig. 1 der Zeichnung ersichtlich ist. Sind die Rahmenränder kreisrund oder oval, so werden diese Einfassungen gewöhnlich auf der Drückerdrehbank oder mittelst eines Ovalwerkes aus einer Blechplatte direct fertig gestellt.The edges of the photo frames or similar objects made of cardboard, leather, wood, Alabaster, glass or other material are often provided with metal frames, which essentially have a cross-section as can be seen from FIG. 1 of the drawing is. If the frame edges are circular or oval, these borders will be common finished directly on the pusher lathe or by means of an oval mechanism from a sheet metal plate posed.
Haben die Rahmen aber geradlinige Ränder, die wie gebräuchlich dann in abgerundeten Ecken zusammenstofsen, Fig. 2, so war man bisher genöthigt, die Einfassung aus einzelnen Stücken zusammenzusetzen, dieselben zu löthen und diesen Ring in einer entsprechenden Form zu pressen.However, the frames have straight edges, which are then rounded as usual If the corners were pressed together, fig To put pieces together, to solder them and this ring in a corresponding shape to press.
Dies Verfahren ist an sich ziemlich umständlich, auch fallen diese Einfassungen nicht immer zur Zufriedenheit aus.This procedure is in itself rather cumbersome, and these borders do not always fall to satisfaction.
Das vorliegende neue Verfahren besteht nun darin, dafs man über einen kreisrunden stählernen Drehbankfutterrand von genau abgepafstem Durchmesser aus einer Blechplatte von bestimmter Dicke einen einfachen rohrartigen Ring drückt und diesen absticht. Für eine nächst kleinere Form kann aus derselben Blechplatte ein kleinerer Ring auf einem zweiten Futterrand gedrückt und abgestochen werden und so fort, bis für die kleinste gebräuchliche Rahmengröfse die Blechplatte fast ohne Abfall aufgebraucht wird.The present new method consists in that one has a circular steel lathe chuck rim of precisely calibrated diameter from a sheet metal plate of a certain thickness presses a simple tubular ring and punctures it. For a next smaller shape can be a smaller ring on a second from the same sheet metal plate The edge of the chuck can be pressed and stabbed and so on, until the smallest ones are used Frame size the sheet metal plate is used up with almost no waste.
Ein so erhaltener Ring, Fig. 3, wird nun in eine zugehörige Stahlform, wie Fig. 4 im Durchschnitt und im Grundrifs zeigt, eingebogen, mit der aus einem Stück bestehenden einfachen Einlegeplatte α darin festgelegt und dann sein hervorstehender Theil χ von der Hand mit einem Drückerstahl über den Rand der Form, wie bei y, nach aufsen gedrückt.A ring obtained in this way, Fig. 3, is now bent into a corresponding steel shape, as Fig. 4 shows in cross section and in outline , fixed in it with the simple insert plate α consisting of one piece and then its protruding part χ by hand a handle steel over the edge of the mold, as with y, pushed outwards.
Ist die Form statt nach aufsen nach innen gestaltet, Fig. 5, so hält statt der Platte α ein entsprechender flacher Stahlrahmen b den Metallring, und dessen Umbörtelung kann mit dem Drückerstahl nach innen erfolgen.If the shape is designed inwards instead of outwards, FIG. 5, then instead of the plate α a corresponding flat steel frame b holds the metal ring, and its flanging can be done inwards with the pusher steel.
Jede Form besteht ihrer bequemen Herstellung wegen aus zwei Stahlrahmen, von denen der eine in dem anderen steckt und mittelst Schrauben c darin befestigt ist.Because of its ease of manufacture, each form consists of two steel frames, one of which is inserted into the other and fastened in it by means of screws c.
