Abstract

PROCEDIMIENTO PARA LA FABRICACION EN GRANDES SERIES DE REMACHES DE CONTACTO TRIMETALICOS POR SOLDADURA EN FRIO. EN PRIMER LUGAR SE FABRICA A PARTIR DE LOS TRES TRAMOS DE ALAMBRE, POR SOLDADURA EN FRIO, UNA PIEZA EN BRUTO SUSTANCIALMENTE CILINDRICA CON DIAMETRO INCREMENTADO Y A CONTINUACION SE OBTIENE LA CABEZA DEL REMACHE POR TRANSFORMACION EN UN EXTREMO DE ESTA PIEZA EN BRUTO EN QUE SE ENCUENTRA EL METAL NOBLE. DURANTE EL PROCESO DE RECALCADO SE EXTRAEN COMPLETAMENTE DEL MANGUITO DE GUIA LOS TRES TRAMOS DE ALAMBRE CON EL FIN DE FORMAR LA PIEZA EN BRUTO SUSTANCIALMENTE CILINDRICA.
