Abstract

Dispositif pour dérouler et enrouler une électrode de fil métallique d'un appareil découpeur par électro-étincelage, comportant une bobine débitrice et une bobine réceptrice, entre lesquelles une électrode de fil métallique est guidée par un système d'éléments de guidage et à travers l'espace d'étincelage. Entre la bobine débitrice 2 et l'espace d'étincelage 7, sur le trajet de l'électrode de fil métallique 1, est montée une poulie tendeuse 3, qui est accouplée à un dispositif de freinage 4, entre l'espace d'étincelage 7 et la bobine réceptrice est montée, sur le trajet de l'électrode de fil métallique 1, une poulie d'entraînement 10, accouplée à un dispositif d'entraînement 11, et l'angle selon lequel l'électrode de fil métallique 1 entoure la poulie tendeuse 3 et la poulie d'entraînement 10 est d'au moins 120 degrés . Application : appareils découpeurs par électro-étincelage.Device for unwinding and winding a metal wire electrode of an electro-spark cutting apparatus, comprising a supply coil and a take-up coil, between which a metal wire electrode is guided by a system of guide elements and through the spark space. Between the supply reel 2 and the spark gap 7, on the path of the wire electrode 1, is mounted a tension pulley 3, which is coupled to a braking device 4, between the spark gap 7 and the take-up reel is mounted, on the path of the wire electrode 1, a drive pulley 10, coupled to a driving device 11, and the angle at which the wire electrode 1 surrounds tension pulley 3 and drive pulley 10 is at least 120 degrees. Application: electro-spark cutting devices.
