Abstract
PROCEDIMIENTO DE FABRICACION DE TORNILLOS AUTORROSCADORES. SU PARTE DE ALAMBRE DE ACERO INOXIDABLE AUSTENITICO DE LA SERIE 300, DE COMPOSICION QUIMICA: 17-18,5 POR 100 DE CROMO; 7,75-8,25 POR 100 DE NIQUEL; 0,06-0,10 POR 100 DE CARBONO; 2,0 POR 100 DE MANGANESO; 1,0 POR 100 DE SILICIO; 0,045 POR 100 DE FOSFORO, Y 0,03 POR 100 DE AZUFRE. ESTE ALAMBRE SE CORTA EN TROZOS DE LONGITUD ADECUADA, A CADA UNO DE LOS CUALES SE LE SOMETE A UNA TECNICA DE FORMACION DE CABEZA EN FRIO DE TIPO CONVENCIONAL PARA PRODUCIR UNA PIEZA INICIAL DE FORMACION DE TORNILLO. ESTAS PIEZAS, PROVISTAS DE CABEZA (38), PASAN A UNA TOLVA VIBRATORIA (28) SOMETIDA A UNA TEMPERATURA CONTROLADA INFERIOR A -40G DONDE SE REFRIGERAN. DE AQUI LAS PIEZAS PASAN A TRAVES DE UN CARRIL (30), DE FORMA ESPIRAL, O OTRO CARRIL DE ALIMENTACION (26), REFRIGERADO E INCLINADO, QUE POR GRAVEDAD LAS ENVIA A LA MAQUINA FORMADORA DE ROSCA POR LAMINACION (20) DE DONDE SALEN LOS TORNILLOS TERMINADOS. EL ROSCADO DE LAS PIEZAS SE LLEVA A CABO EN ESTADO REFRIGERADO, PARA PRODUCIR UNA TRANSFORMACION PARCIAL DE LA AUSTENITA EN MARTENSITA.
