Abstract

La piattaforma magnetica comporta sulla sua faccia attiva (5) delle espansioni polari fisse (4) disposte a dama, costituenti dei poli attivi alternativamente Nord e Sud, tanto che nel senso longitudinale che nel senso trasversale. Dei magneti permanenti fissi (6), di polarità alternate, sono inseriti tra le espansioni polari (4) secondo la direzione longitudinale o trasversale della piattaforma. Sotto all'insieme delle espansioni polari (4) è previsto un insieme di magneti permanenti mobili (19), tutti i magnetizzati perpendicolarmente alla faccia attiva (5) e disposti a dama con delle plarità alternate. Tutti i magneti mobili (19) sono montati su un supporto comune collegato ad un dispositivo di comando, per la commutazione posizione attiva - posizione neutra.Applicazione al ritegno di pezzi in lavorazione.
