Description

Die Herstellung von Scheren war bisher sehr teuer und umständlich. Auch entsteht beispielsweise bei der Herstellung von Scheren auf kaltem Wege infolge des großen Fingerauges ein sehr großer Werkstoffabfall.The manufacture of scissors has previously been very expensive and cumbersome. Also arises, for example When producing scissors by cold means, a very large amount of material is wasted due to the large finger eye.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Scheren auf kaltem Wege, bei welchem fast jeder Abfall vermieden wird. Es wird dadurch gegenüber den bisher gebrauchte liehen Herstellungsverfahren an Arbeit und Werkstoff gespart. Die Erfindung besteht darin, daß aus einem Metallstreifen ein Rohling mit langgestrecktem flach aneinanderliegenden Augenteil gestanzt, hierauf das Auge aufgeweitet und schließlich der Rohling nachgeprägt oder die Schneide in Querrichtung ausgewalzt wird. Auf der Zeichnung ist die neue Herstellungsweise der Scheren in zwei etwas voneinander abweichenden Ausführungsbeispielen dargestellt. so Wie Abb. ι zeigt, wird aus einem schmalen Streifen α der Rohling b für die herzustellende Schere durch Stanzen gewonnen. Da das Auge e langgestreckt und flach aneinander liegt und da sich zur Ausnutzung des Werkstoffs die Enden der auszustanzenden Teile übergreifen, so entsteht ein nur sehr geringer Abfall. Das Auge c des Rohlings wird nunmehr gemäß Abb. 2 aufgeweitet und gerundet, worauf entweder der Rohling noch einmal vollständig nachgeprägt und hierbei die Schneide entsprechend flach gedrückt oder aber die Verjüngung der Schneide durch Auswalzen in Querrichtung erzielt wird. Durch das Nachprägen bzw. Querwalzen erhält der Scherenteil die in Abb. 3 und 4 dargestellte Fertigform, die fast gar keiner Nacharbeit mehr bedarf.The invention relates to a process for the production of scissors by cold means, in which almost all waste is avoided. This saves work and material compared to the previously used borrowed manufacturing process. The invention consists in punching a blank with an elongated, flatly abutting eye part from a metal strip, then widening the eye and finally stamping the blank or rolling out the cutting edge in the transverse direction. In the drawing, the new method of making the scissors is shown in two slightly different exemplary embodiments. As Fig. ι shows, the blank b for the scissors to be produced is obtained by punching from a narrow strip α. Since the eye e lies elongated and flat against one another and since the ends of the parts to be punched out overlap in order to utilize the material, there is only very little waste. The eye c of the blank is now widened and rounded as shown in Fig. 2, whereupon either the blank is completely re-embossed and the cutting edge is pressed flat accordingly, or the cutting edge is tapered by rolling out in the transverse direction. The re-embossing or cross-rolling gives the scissors part the finished form shown in Figs. 3 and 4, which requires almost no reworking.

Bei der Herstellungsweise nach Abb. 5 wird der stärkere Scherenteil mit dem Auge d wie vorher beschrieben hergestellt, während die Schneide e für sich gestanzt, geprägt bzw. ausgewalzt und sodann mittels Schweißung mit dem Auge verbunden wird. Diese Schweißung kann sowohl wie dargestellt stumpf als auch überlappt an der Nietstelle erfolgen.In the production method according to Fig. 5, the stronger scissors part with the eye d is produced as described above, while the cutting edge e is punched, embossed or rolled out and then connected to the eye by means of welding. This welding can be done either butt, as shown, or with an overlap at the riveting point.
