Description
Verfahren zur Herstellung von Uhrgehäusen und Rahmen aus starkem Blech. Die bisher übliche Herstellungsart von metallenen Gehäuserahmen, wie solche hauptsächlich in der Uhrenfabrikation verwendet werden, war durch Ziehen mit einer Ziehpresse. Dieses Verfahren ist jedoch wegen dem hohen Werkzeugaufwand sehr teuer und umständlich, auch kann mit ein- und demselben Werkzeug immer nur eine einzige ganz genau bestimmte Ausführungsform hergestellt werden. Messerscharfe Ecken bzw. Kanten können nicht durch Ziehen, sondern müssen durch Stauchen oder Nachschleifen hergestellt werden.Process for the production of watch cases and frames from strong sheet metal. The usual way of manufacturing metal housing frames, such as those mainly Used in watchmaking was by drawing with a drawing press. However, this process is very expensive and cumbersome because of the high number of tools required, also, with one and the same tool, only one very precisely defined tool can ever be used Embodiment are produced. Razor-sharp corners or edges cannot by pulling, but must be made by upsetting or regrinding.
Die Herstellung solcher Rahmen aus winkeleisenförmig gezogenem Material kann schon allein wegen der Nahtbildung äuf der Vorderfläche nicht in Frage kommen.The production of such frames from material drawn in the shape of an angle iron cannot be considered because of the seams on the front surface alone.
Diesen L`belständen wird durch das beschriebene neue Verfahren in der einfachsten Weise abgeholfen, indem mit Hilfe einer einzigen einfachen auf jeder Dreh-, Drückhank o. dgl. verwendbaren Vorrichtung die verschiedensten Rahmengrößen herstellbar sind. Das Verfahren besteht darin, daß in einen flachen Metallrahmen Rillen eingefräst werden, deren Einfrästiefe sich nach der Kantenabrundung richtet, die der Rahmen nach Umbiegung der Seitenteile erhalten soll.The new method described in the easiest way remedied by using a single simple on each Rotating, pushing handle or the like. Usable device the most varied frame sizes can be produced. The procedure is that in a flat metal frame Grooves are milled, the milling depth of which depends on the rounding of the edge, which the frame should receive after bending the side parts.
Die Seitenteile werden, nachdem die überflüssigen Eckstücke abgebrochen sind, umgebogen und die Naht oder Stoßfugen zusammengelötet.The side parts are broken off after the superfluous corner pieces are bent over and the seam or butt joints soldered together.
Zu diesem Zweck dient die nachfolgend beschriebene Vorrichtung. Auf der Zeichnung bedeutet: Abb. i die Vorderansicht der auf einer Drehbank sitzenden Vorrichtung, Abb. z die Seitenansicht der Vorrichtung, Abb.3 die Oberansicht der Vorrichtung, Abb. q. die Oberansicht eines flachen Metallrahmens mit eingefrästen Rillen, Abb. 5 die Seitenansicht der Abb. q. und Abb.6 die Seitenansicht eines fertigen Gehäuserahmens.The device described below is used for this purpose. on of the drawing means: Fig. i the front view of the person sitting on a lathe Device, Fig. Z the side view of the device, Fig.3 the top view of the Device, Fig.q. the top view of a flat metal frame with milled Grooves, Fig. 5 the side view of Fig. Q. and Fig.6 the side view of a finished Housing frame.
Auf der Wange a einer Dreh- oder Drückbank ist ein Support aufgesetzt, der allseitig verstell- und feststellbar ist. Dieser Support trägt eine Platte b, die leicht von Hand senkrecht zur Wange verschiebbar ist. Auf dieser Platte b wird der genau zugeschnittene flache Metallrahmen c auf- und an den Anschlägen d angelegt. Mit Hilfe der scharnierartig an der Platte b angelenktenAndrückvorrichtung k wird der Metallrahmen c durch Handdruck auf die Platte b gedrückt und die Platte b unter dein Fräser e durchgezogen, wobei die Rille f eingefräst wird. Der Vorgang wird auf jeder Seite des flachen Metallrahmens c wiederholt, die umgebogen werden soll. Nun werden die überflüssigen Eckstücke g abgebrochen und die Seitenteile h. umgebogen, dann werden die Längsnähte und die Ecken zusammengelötet.A support that can be adjusted and locked on all sides is placed on the cheek a of a lathe or press bench. This support carries a plate b, which can easily be moved by hand perpendicular to the cheek. The precisely cut flat metal frame c is placed on this plate b and placed against the stops d. With the aid of the pressing device k, which is hinged to the plate b, the metal frame c is pressed onto the plate b by hand pressure and the plate b is pulled through under the milling cutter e, the groove f being milled. The process is repeated on each side of the flat metal frame c that is to be bent. Now the superfluous corner pieces g are broken off and the side pieces h. bent over, then the longitudinal seams and the corners are soldered together.
Die gewünschte Tiefe der Einfräsung, von der die Schärfe oder Rundung der Kanten i abhängig ist, wird durch Verstellung der Platte b in der Höhe erreicht.The desired depth of the milling, from which the sharpness or rounding depends on the edges i is achieved by adjusting the height of the plate b.
