Navoji mehani\u010dkog zatvara\u010da, bez obzira da li se radi o a\u00a0vijak sa glavom<\/u>,\u00a0rod<\/u>, ili\u00a0shop unutra<\/u>, mo\u017ee se proizvoditi rezanjem ili valjanjem. Razlike, zablude, prednosti i nedostaci svake metode opisani su u nastavku.<\/p>\n

Rolled Threads<\/b><\/strong><\/h3>\n

Uvla\u010denje navoja je proces kojim se \u010delik ekstrudira kako bi se formirao navojni dio pri\u010dvr\u0161\u0107iva\u010da, umjesto da se uklanja kao kod rezanog navoja. U ovom procesu, vijak se proizvodi od okrugle \u0161ipke smanjenog promjera. Na primjer, vijak promjera 1\u2033 se proizvodi od okrugle \u0161ipke pre\u010dnika .912\u2033. Ovaj materijal \"pre\u010dnika nagiba\" je otprilike sredi\u0161nja ta\u010dka izme\u0111u glavnog pre\u010dnika (vrhova) i manjeg pre\u010dnika (doline) navoja. Vijak se \u201eprovla\u010di\u201c kroz set kalupa za navoje koji istiskuju \u010delik i formiraju navoje. Krajnji rezultat je zatvara\u010d s punim dijelom s navojem pre\u010dnika 1\u2033, ali smanjenim pre\u010dnikom tijela (.912). Uvla\u010denje navoja je izuzetno efikasan proces i \u010desto rezultira zna\u010dajnim u\u0161tedama. Prema tome, Portland Bolt \u0107e motati niti kad god je to mogu\u0107e.<\/p>\n

 <\/p>\n

Tehni\u010dki, bilo koja specifikacija osim strukturnih vijaka A325 i A490 mo\u017ee se proizvesti sa smanjenim tijelom i valjanim navojem.<\/p>\n

 <\/p>\n

Vijak sa smanjenim tijelom bit \u0107e slabiji od vijka s tijelom pune veli\u010dine.<\/p>\n

Najslabija oblast svakog mehani\u010dkog zatvara\u010da je manji pre\u010dnik navoja. Budu\u0107i da su dimenzije navoja rezanog konca i uvijenog u\u010dvr\u0161\u0107iva\u010da identi\u010dne, nema apsolutno nikakve razlike u \u010dvrsto\u0107i. Moglo bi se zapravo tvrditi da stvrdnjavanje koje se javlja tokom procesa uvla\u010denja navoja mo\u017ee \u010dak i u\u010diniti pri\u010dvr\u0161\u0107iva\u010d sa valjanim nitima ja\u010dim. Dodatno, rezano narezivanje prekida prirodnu zrnastu strukturu okrugle \u0161ipke, dok je urezivanje navoja reformi\u0161e. Moglo bi se opet tvrditi da urezivanje u zrno okrugle \u0161ipke prilikom rezanog urezivanja navoja mo\u017ee proizvesti niti koji imaju manji strukturalni integritet od dijela koji je uvu\u010den u valjak.<\/p>\n

Prednosti Roll Threading<\/i><\/em><\/p>\n

    \n
  1. Zna\u010dajno kra\u0107e vrijeme rada zna\u010di ni\u017ee tro\u0161kove.<\/li>\n
  2. Budu\u0107i da vijak s navojem ima manji promjer tijela, te\u017ei je manje od njegovog punog tijela. Ovo smanjenje te\u017eine smanjuje cijenu \u010delika, pocin\u010davanja, termi\u010dke obrade, galvanizacije, transporta i sve druge tro\u0161kove povezane s pri\u010dvr\u0161\u0107iva\u010dem koji se temelje na te\u017eini.<\/li>\n
  3. Hladna obrada \u010dini navoje otpornijim na o\u0161te\u0107enja tokom rukovanja.<\/li>\n
  4. Namotani konci su \u010desto glatkiji zbog efekta bru\u0161enja tokom operacije valjanja.<\/li>\n<\/ol>\n

    Nedostaci uvla\u010denja navoja<\/i><\/em><\/p>\n

      \n
    1. Dostupnost okrugle \u0161ipke promjera koraka je ograni\u010dena za odre\u0111ene razrede materijala.<\/li>\n<\/ol>\n

      Cut Threads<\/b><\/strong><\/h3>\n

      Rezanje navoja je proces kojim se \u010delik odsije\u010de ili fizi\u010dki uklanja sa okrugle \u010deli\u010dne \u0161ipke kako bi se formirali navoji. Na primjer, vijak promjera 1 in\u010da se proizvodi rezanjem navoja u cijelo tijelo vijka promjera 1 in\u010da.<\/p>\n

      Prednosti urezivanja niti<\/i><\/em><\/p>\n

        \n
      1. Nekoliko ograni\u010denja u pogledu pre\u010dnika i du\u017eine navoja.<\/li>\n
      2. Sve specifikacije mogu biti proizvedene sa rezanim navojem.<\/li>\n<\/ol>\n
