Abstract

Um bei der Herstellung von Endelektroden aus Kupfer für gasgefüllte Überspannungsableiter mittels einer einstufigen Doppeldruckpresse von einem Rohling ausgehen zu können, der volumengleich zum Fertigteil ist, ist die Einzugseinrichtung des Schneidwerkzeuges auf eine Einzugslänge einstellbar, die kleiner als der Drahtdurchmesser ist, ist die Vorstauchnadel (22) des Preßwerkzeuges auf eine bestimmte Eindringtiefe in die Matrize (10) eingestellt und ist die Matrize (10) des Preßwerkzeuges mit einer speziell dimensionierten Einsatzbüchse (14) versehen.

In order to be able to start in the production of end electrodes made of copper for gas-filled surge by means of a single-stage double pressure from a blank which is equal in volume to the finished part, the collection device of the cutting tool is adjustable to a catch length, which is smaller than the wire diameter, the pre-piercing needle (22 ) of the pressing tool set to a certain depth of penetration into the die (10) and the die (10) of the pressing tool with a specially dimensioned insert sleeve (14) is provided.
