Description

Verfahren zur Herstellung von Präzisionskontaktkörpern Präzisionskontaktkörper, wie solche beispielsweise in Zerhackern benutzt werden, wurden bisher in der Weise hergestellt, daß aus einem geeigneten Werkstoff eine Kontaktplatte angefertigt wurde, die dann auf ein aus einem anderen Werkstoff hergestelltes Tragstück aufgelötet wurde, worauf der Kontaktkörper auf einer Drehbank durch Abdrehen. des Tragstückes fertiggestellt wurde. Abgesehen von den erheblichen Kosten für die Dreharbeit wurde auch die Kontaktplatte häufig verbogen oder beim Einspannen in die Drehbank mit einem Grat versehen, so daß eine weitere Bearbeitung notwendig wurde. Insbesondere bei der Anwendung der Kontaktkörper für Zerhacken ist es notwendig, daß diese enge Formtoleranzen aufweisen, so daß diesen Bedingungen nicht entsprechende Kontaktkörper zurückgewiesen werden mußten. Um diesen Übelständen abzuhelfen, wird gemäß der Erfindung bei der Herstellung der Kontaktkörper von der teuren Dreharbeit ganz abgesehen und die Tragstücke aus geeignetem Werkstoff kalt geschlagen, worauf dann die Kontaktplättchen auf die geschlagenen Träger aufgelötet werden.Process for the production of precision contact bodies Precision contact bodies, how such are used, for example, in choppers, have hitherto been in the manner manufactured so that a contact plate was made from a suitable material, which is then soldered onto a support piece made from a different material whereupon the contact body was turned on a lathe. of the support piece has been completed. Apart from the significant cost of filming it was also the contact plate is often bent or when it is clamped in the lathe provided a ridge, so that further processing was necessary. In particular when using the contact bodies for chopping, it is necessary that they be tight Have shape tolerances, so that these conditions do not correspond to the contact body had to be rejected. In order to remedy these drawbacks, according to the invention quite apart from the expensive turning work in the manufacture of the contact body and the support pieces made of a suitable material cold-beaten, whereupon the contact plates be soldered onto the beaten carrier.

Mit dem neuen Verfahren werden die Kontaktkörper wesentlich billiger und mit weniger Ausschuß als bisher hergestellt.With the new process, the contact bodies are much cheaper and produced with less scrap than before.

Die gebräuchlichen Tragstücke für die Kontakte bestehen aus Eisen oder Kupfer. Beide Metalle können nur in ganz reinem Zustand verwendet werden, da sonst das Auflöten des Kontaktplättchens infolge der Verunreinigungen Schwierigkeiten macht. Es hat sich nun herausgestellt, daß sich Elektrolytkupfer auch seiner günstigenWiderstandsverhältnisse wegen am besten für das neue Verfahren eignet.The common support pieces for the contacts are made of iron or copper. Both metals can only be used in a very pure state, since otherwise the soldering of the contact plate difficulties due to the contamination power. It has now been found that electrolytic copper also has its favorable resistance ratios because it is best suited for the new procedure.
