Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Kontaktstücken mit annähernd halbkreisförmigem Querschnitt. Derartige Kontaktstücke werden vielfach durch Ziehen hergestellt. Da sich das Ziehen aber nur für größere Miengen lohnt, war man bisher gezwungen, Kontaktstücke, die nur in verhältnismäßig geringen Mengen benötigt wurden, durcli Ausfräsen oder auf andere umständlicheThe invention relates to a method for producing contact pieces with approximately semicircular cross-section. Such contact pieces are often by pulling manufactured. Since pulling is only worthwhile for larger amounts, you have been so far forced to use contact pieces that were only needed in relatively small quantities, by milling out or on other awkward ones

ίο Weise herzustellen.ίο way to manufacture.

Gemäß der Erfindung werden die Kontakte dadurch hergestellt, daß handelsübliche Werkstoff e in Form von Streifen zu einer Flachspule mit großer radialer Breite aufgewikkelt und durch anschließendes Pressen in die gewünschte Profilform gebracht werden. Die Flachmetallstreifen können entweder vor oder nach der Formgebung des Kontaktstückes auf die erforderliche Länge abgeschnitten werden. Auch können die Äbschneid-, Wickelünd Formänderungsarbeiten entweder in einem einzigen oder in mehreren hintereinander bzw. parallel folgenden Arbeitsgängen stattfinden.According to the invention, the contacts are made that commercially available material e wound up in the form of strips to form a flat coil with a large radial width and brought into the desired profile shape by subsequent pressing. the Flat metal strips can either before or after the shaping of the contact piece cut to the required length. The Äbschneid-, Wickelünd Deformation work either in a single or in several consecutive or the following operations take place in parallel.

Das Verfahren gemäß der Erfindung soll an Hand der Abb. 1 bis 3 näher erläutert werden. Abb. 1 zeigt einen Flachstab von handelsüblicher Form aus leitendem Metall, beispielsweise aus Kupfer, der, wie Abb. 2 zeigt, zu einer Flachspule mit größerer radialer Breite aufgewickelt wird. Durch anschließendes Pressen erhält diese Flachspule die in Abb. 3 dargestellte Profilform, die als Kontaktstück verwendet werden soll. Statt dessen kann die in Abb. 2 dargestellte Spule auch jede andere geeignete Profilform erhalten. The method according to the invention will be explained in more detail with reference to FIGS will. Fig. 1 shows a flat bar of commercially available form made of conductive metal, for example made of copper, which, as Fig. 2 shows, results in a flat coil with a larger radial Width is wound. Subsequent pressing gives this flat coil the profile shape shown in Fig. 3, which is to be used as a contact piece. Instead of the coil shown in Fig. 2 can also have any other suitable profile shape.
