Abstract

TORNILLO DE ROSCA DE CHAPA DE PUNTA LARGA Y METODO DE FABRICACION. UN TORNILLO DE ROSCA DE CHAPA DE PUNTA LARGA (20) Y METODO PARA LA FORMACION DE UN TORNILLO DE ROSCA DE CHAPA TAL. EL TORNILLO DE ROSCA DE CHAPA (20) FORMADO POR ESTE METODO ESTABILIZA EL TORNILLO DURANTE EL PASO DE PERFORACION DEL ORIFICIO DE ARRASTRE DEL TORNILLO Y PRODUCE UN ORIFICIO DIMENSIONADO CON PRECISION PARA RECIBIR LA PARTE ROSCADA DEL TORNILLO. EL METODO DE FORMACION DEL TORNILLO DE ROSCA DE CHAPA SE INICIA PROPORCIONANDO UN PRIMORDIO DE TORNILLO SIN ROSCAR (22) QUE TIENE UN EXTREMO DE CABEZA (26) Y UNA PUNTA (28). SE FORMA UNA CABEZA DE ARRASTRE (30) EN EL EXTREMO DE CABEZA (26) Y UNA PARTE DE PERFORACION (40) EN EL CUERPO (24) DISTAL DEL EXTREMO DE CABEZA (26). SE FORMAN DOS ACANALADURAS (38) QUE SE EXTIENDEN LONGITUDINALMENTE EN LA PARTE DE PERFORACION (40) DEL CUERPO (24) DESDE LA PUNTA (28) HACIA EL EXTREMO DE CABEZA (26). CADA ACANALADURA (38) INCLUYE UN BORDE DE TRABAJO (42) Y UN BORDE TERMINAL (44). LOS BORDES DE TRABAJO (42) Y LOS BORDES TERMINALES (44) DE LAS DOS ACANALADURAS (38) ESTAN RESPECTIVA Y DIAMETRALMENTE OPUESTOS EN EL CUERPO (24). UN DIAMETRO TERMINAL (48) MEDIDO A TRAVES DE LOS BORDES TERMINALES (44) DIAMETRALMENTE OPUESTOS ES MAYOR QUE EL DIAMETRO DE TRABAJO (62) MEDIDO A TRAVES DE LOS BORDES DE TRABAJO (42) DIAMETRALMENTE OPUESTOS. A CONTINUACION, LA PARTE DE PERFORACION (40) SE ROSCA ENTRE DOS RODILLOS TROQUELADORES COMPLEMENTARIOS DE MOVIMIENTOS OPUESTOS (52) PARA ROSCAR LOS BORDES TERMINALES (44) INTERIORMENTE. EL ROSCADO DE LOS BORDES TERMINALES (44) EN LA PARTE DE PERFORACION (40) FORMA BORDES TERMINALES ROSCADOS (60). DESPUES DE ROSCAR LA PARTE DE PERFORACION (40), UN DIAMETRO TERMINAL ROSCADO MEDIDO A TRAVES DE LOS BORDES TERMINALES ROSCADOS (60) ES SUSTANCIALMENTE IGUAL AL DIAMETRO DE TRABAJO (62). FINALMENTE, SE FORMAN ROSCAS (66) EN EL CUERPO (24), GENERALMENTE ENTRE EL EXTREMO DE CABEZA (26) Y LA PARTE DE PERFORACION (40).
