Abstract
PROCEDIMIENTO PARA LA OBTENCION DE UN ELEMENTO DE ACERO INOXIDABLE, PARA SUJECION, FORMADO POR UNA CABEZA Y UN VASTAGO. UN ALAMBRE O UNA VARILLA DE ACERO INOXIDABLE, DE RESISTENCIA A LA TRACCION COMPRENDIDA ENTRE 5.250 Y 8.750 KG-CM2, SE ENFRIA HASTA UNA TEMPERATURA INFERIOR A -75 C. POSTERIORMENTE SE ESTIRA EN FRIO HASTA CONSEGUIR QUE EL AREA SE REDUZCA EN, APROXIMADAMENTE, EL 3 POR 100 Y LA RESUSTENCIA A LA TRACCION AUMENTE HASTA UN VALOR COMPRENDICO ENTRE 5250 Y 11200 KG-CM2. POR ULTIMO, SE DIVIDE EN TROZOS Y SE FORMA EN FRIO LA CABEZA DEL ELEMENTO. DE APLICACION EN LA FABRICACION DE PERNOS ROSCADOS O SIN ROSCAR, DE TORNILLOS Y DE REMACHES.
