Abstract

REMACHES DE CONTACTO ELECTRICO CON UN VASTAGO Y CON UNA O CON DOS CABEZAS SE FABRICAN POR RECALCADO DE TROZOS DE ALAMBRE EN UNA HERRAMIENTA DE CONFORMADO. PARA FORMAR POR LO MENOS UNA DE LAS CABEZAS SE EMPLEA UN TROZO DE UN ALAMBRE ENROLLADO, CUYO ENROLLADO ESTA HECHO DE UN MATERIAL METALICO MAS DUCTIL QUE EL NUCLEO DEL ALAMBRE RODEADO POR LA VUELTA.ELECTRIC CONTACT RIVETS WITH A STEM AND WITH ONE OR TWO HEADS ARE MANUFACTURED BY STAMPING OF WIRE PIECES IN A FORMING TOOL. TO CREATE AT LEAST ONE OF THE HEADS, A PIECE OF A COILED WIRE IS USED, WHOSE COIL IS MADE OF A MORE DUCTILE METALLIC MATERIAL THAN THE CORE OF THE WIRE SURROUNDED BY THE TURN.
