Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UN ELEMENTO DE ACERO INOXIDABLE, PARA SUJECION, FORMADO POR UNA CABEZA Y UN VASTAGO. UN TROZO DE ACERO INOXIDABLE QUE TIENE UNA TEMPERATURA MD30, COMPRENDIDA ENTRE -50 Y 50 C. SIENDO MD30 LA TEMPERATURA A LA CUAL, DESPUES DE UNA DEFORMACION VERDADERA A TRACCION DEL 30 POR 100, LA MUESTRA CONTIENE UN 50 POR 100 DE MARTENSITA; SE ENFRIA, AL MENOS, HASTA UNA TEMPERATURA INFERIOR EN 50 C. A LA TEMPERATURA MD30. A CONTINUACION SE EXTRUYE UNA PARTE DEL TROZO ENFRIADO PARA OBTENER EL VASTAGO Y LA PARTE RESTANTE SE CALIENTA, SIMULTANEAMENTE, HASTA UNA TEMPERATURA COMPRENDIDA ENTRE MD30 Y 500 C. POR ULTIMO, SE RECALCA LA PARTE RECALENTADA PARA FORMAR LA CABEZA. DE APLICACION EN LA FABRICACION DE PERNOS ROSCADOS O SIN ROSCA, DE TORNILLOS Y DE REMACHES.
