Abstract

A.PROCEDE POUR LA FABRICATION D'UNE PIECE POLAIRE POUR MACHINE ELECTRIQUE, PAR FORMAGE SANS ENLEVEMENT DE COPEAUX, D'UNE EBAUCHE EN PROFILE LAMINE TUBULAIRE. B.PROCEDE CARACTERISE EN CE QUE LA ZONE 12 DU NOYAU DE LA PIECE POLAIRE 10 PREND SA FORME FINALE AU COURS D'UNE PREMIERE ETAPE DE FORMAGE, DES OREILLES 18 DE LA PIECE POLAIRE 10 ETANT COMPRIMEES JUSQU'A LEUR FORME FINALE PAR LA ZONE DU NOYAU 12, DETENDUE, AU COURS D'UNE DEUXIEME ETAPE DE FORMAGE, ET SANS TRAITEMENT THERMIQUE INTERMEDIAIRE. C.PROCEDE APPLICABLE AU FORMAGE DE PIECES POLAIRES.A.PROCEDE FOR THE MANUFACTURE OF A POLAR PART FOR AN ELECTRIC MACHINE, BY FORMING WITHOUT REMOVING CHIPS, OF A BLANK IN TUBULAR LAMINATED PROFILE. B. PROCESS CHARACTERIZED IN THAT THE ZONE 12 OF THE CORE OF THE POLAR PIECE 10 TAKES ITS FINAL FORM DURING A FIRST FORMING STEP, EARS 18 OF THE POLAR PIECE 10 BEING COMPRESSED TO THEIR FINAL FORM BY THE ZONE OF CORE 12, RELAXED, DURING A SECOND STAGE OF FORMING, AND WITHOUT INTERMEDIATE HEAT TREATMENT. C. PROCEDURE APPLICABLE TO THE FORMING OF POLAR PIECES.
