Roscas dun elemento de fixaci\u00f3n mec\u00e1nico, independentemente de que se trate de a\u00a0parafuso de cabeza<\/u>,\u00a0vara<\/u>, ou\u00a0mercar dentro<\/u>, pode ser producido por corte ou rolo. A continuaci\u00f3n descr\u00edbense as diferenzas, conceptos err\u00f3neos, vantaxes e inconvenientes de cada m\u00e9todo.<\/p>\n

F\u00edos enrolados<\/b><\/strong><\/h3>\n

A rosca en rolo \u00e9 un proceso polo cal o aceiro \u00e9 extruido para formar a parte roscada dun elemento de fixaci\u00f3n, en lugar de ser eliminado como ocorre no rosca cortada. Neste proceso, un parafuso \u00e9 fabricado a partir dunha barra redonda de di\u00e1metro reducido. Por exemplo, un parafuso de 1\u2033 de di\u00e1metro est\u00e1 fabricado a partir dunha barra redonda de .912\u2033 de di\u00e1metro. Este material de \"di\u00e1metro de paso\" \u00e9 aproximadamente o punto medio entre o di\u00e1metro maior (picos) e o di\u00e1metro menor (vales) dos f\u00edos. O parafuso \u00e9 \"enrolado\" a trav\u00e9s dun conxunto de matrices de rosca que despraza o aceiro e forma os f\u00edos. O resultado final \u00e9 un elemento de fixaci\u00f3n cunha parte roscada de 1\u2033 de di\u00e1metro completo pero un di\u00e1metro corporal reducido (.912). O enhebrado de rolos \u00e9 un proceso extremadamente eficiente e adoita producir importantes aforros de custos. Polo tanto, Portland Bolt rolar\u00e1 f\u00edos sempre que sexa posible.<\/p>\n

 <\/p>\n

Tecnicamente, calquera especificaci\u00f3n, con excepci\u00f3n dos parafusos estruturais A325 e A490, p\u00f3dese producir cun corpo reducido e roscas laminadas.<\/p>\n

 <\/p>\n

Un parafuso cun corpo reducido ser\u00e1 m\u00e1is d\u00e9bil que un parafuso cun corpo de tama\u00f1o completo.<\/p>\n

A zona m\u00e1is d\u00e9bil de calquera fixador mec\u00e1nico \u00e9 o di\u00e1metro menor dos f\u00edos. Dado que as dimensi\u00f3ns do f\u00edo cortado e do suxeidor do f\u00edo laminado son id\u00e9nticas, non hai absolutamente ningunha diferenza de forza. P\u00f3dese argumentar que o endurecemento que se produce durante o proceso de enhebrado do rolo pode incluso facer que o peche con f\u00edos laminados sexa m\u00e1is forte. Ademais, o roscado cortado interrompe a estrutura natural do gran da barra redonda mentres que o roscado de rolo a reforma. P\u00f3dese argumentar de novo que cortar o gran dunha barra redonda ao cortar o roscado pode producir f\u00edos que te\u00f1en menos integridade estrutural que unha peza que foi roscada en rolo.<\/p>\n

Vantaxes do roscado de rolos<\/i><\/em><\/p>\n

    \n
  1. Os tempos de traballo significativamente m\u00e1is curtos significan custos m\u00e1is baixos.<\/li>\n
  2. Debido a que un parafuso roscado en rolo ten un di\u00e1metro de corpo menor, pesa menos que o seu corpo completo. Esta reduci\u00f3n de peso reduce o custo do aceiro, galvanizaci\u00f3n, tratamento t\u00e9rmico, chapado, transporte e calquera outro custo asociado co elemento de fixaci\u00f3n que se basea no peso.<\/li>\n
  3. O traballo en fr\u00edo fai que os f\u00edos sexan m\u00e1is resistentes aos danos durante a manipulaci\u00f3n.<\/li>\n
  4. Os f\u00edos laminados adoitan ser m\u00e1is suaves debido ao efecto de bru\u00f1ido da operaci\u00f3n de laminaci\u00f3n.<\/li>\n<\/ol>\n

      \n
    1. A dispo\u00f1ibilidade de barras redondas de di\u00e1metro de paso est\u00e1 limitada para certas calidades de materiais.<\/li>\n<\/ol>\n

      Cortar F\u00edos<\/b><\/strong><\/h3>\n

      O roscado de corte \u00e9 un proceso polo cal o aceiro \u00e9 cortado ou eliminado fisicamente dunha barra redonda de aceiro para formar os f\u00edos. Un parafuso de 1 \"de di\u00e1metro, por exemplo, prod\u00facese cortando f\u00edos nun corpo completo de 1\" de di\u00e1metro do parafuso.<\/p>\n

      Vantaxes do roscado de corte<\/i><\/em><\/p>\n

        \n
      1. Poucas limitaci\u00f3ns en canto ao di\u00e1metro e lonxitude da rosca.<\/li>\n
      2. Todas as especificaci\u00f3ns p\u00f3dense fabricar con f\u00edos cortados.<\/li>\n<\/ol>\n
