Navoji mehanske sponke, ne glede na to, ali gre za\u00a0vijak z glavo<\/u>,\u00a0palica<\/u>, oz\u00a0trgovina notri<\/u>, se lahko proizvaja z rezanjem ali valjanjem. Spodaj so opisane razlike, napa\u010dne predstave, prednosti in slabosti vsake metode.<\/p>\n

Valjane niti<\/b><\/strong><\/h3>\n

Rezanje navojev v zvitku je postopek, pri katerem je jeklo ekstrudirano, da se oblikuje navojni del pritrdilnega elementa, namesto da bi ga odstranili kot pri rezanju navojev. Pri tem postopku je sornik izdelan iz okrogle palice z zmanj\u0161anim premerom. Na primer, vijak s premerom 1\u2033 je izdelan iz okrogle palice s premerom 0,912\u2033. Ta material \"premera koraka\" je pribli\u017eno sredina med glavnim premerom (vrhovi) in manj\u0161im premerom (doline) navojev. Vijak se \"valja\" skozi niz navojnih matric, ki premakne jeklo in oblikuje navoje. Kon\u010dni rezultat je pritrdilni element s polnim navojnim delom s premerom 1\u2033, vendar z zmanj\u0161anim premerom telesa (.912). Vrezovanje navojev v zvitke je izjemno u\u010dinkovit postopek in pogosto povzro\u010di znatne prihranke pri stro\u0161kih. Zato bo Portland Bolt navijal niti, kadar koli bo to mogo\u010de.<\/p>\n

 <\/p>\n

Tehni\u010dno je mogo\u010de vse specifikacije, razen konstrukcijskih vijakov A325 in A490, izdelati z zmanj\u0161anim telesom in valjanimi navoji.<\/p>\n

 <\/p>\n

Vijak z zmanj\u0161anim telesom bo \u0161ibkej\u0161i od sornika s telesom polne velikosti.<\/p>\n

Naj\u0161ibkej\u0161a to\u010dka katerega koli mehanskega pritrdila je manj\u0161i premer navojev. Ker sta dimenziji navoja rezanega in valjanega navojnega pritrdila enaki, ni prav nobene razlike v trdnosti. Dejansko bi lahko trdili, da lahko utrjevanje, ki se pojavi med postopkom vrezovanja navojev v zvitke, celo okrepi pritrdilni element z valjanimi navoji. Poleg tega rezani navoj prekine naravno zrnato strukturo okrogle palice, medtem ko jo navojni navoj preoblikuje. Ponovno bi lahko trdili, da lahko vrezovanje v zrnatost okrogle palice pri rezanem navoju povzro\u010di navoje, ki imajo manj\u0161o strukturno celovitost kot del, ki je bil navit kot valj.<\/p>\n

Prednosti vrezovanja navojev v zvitke<\/i><\/em><\/p>\n

    \n
  1. Bistveno kraj\u0161i delovni \u010das pomeni ni\u017eje stro\u0161ke.<\/li>\n
  2. Ker ima sornik z navojem v zvitku manj\u0161i premer telesa, tehta manj kot njegovo polno telo. To zmanj\u0161anje te\u017ee zmanj\u0161a stro\u0161ke jekla, cinkanja, toplotne obdelave, galvanizacije, prevoza in vse druge stro\u0161ke, povezane s pritrdilnim elementom, ki temeljijo na te\u017ei.<\/li>\n
  3. Hladna obdelava naredi niti bolj odporne na po\u0161kodbe med rokovanjem.<\/li>\n
  4. Valjani navoji so pogosto bolj gladki zaradi u\u010dinka \u017eganja pri valjanju.<\/li>\n<\/ol>\n

    \u00a0<\/i><\/em><\/p>\n

    Slabosti navoja v zvitku<\/i><\/em><\/p>\n

      \n
    1. Razpolo\u017eljivost okrogle palice z nagibnim premerom je omejena za nekatere vrste materialov.<\/li>\n<\/ol>\n

      \u00a0<\/i><\/em><\/p>\n

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

      Rezanje navojev je postopek, s katerim se jeklo odre\u017ee ali fizi\u010dno odstrani iz okrogle jeklene palice, da se oblikujejo niti. Vijak s premerom 1\u2033 se na primer izdela z rezanjem navojev v celotno telo vijaka s premerom 1\u2033.<\/p>\n

      Prednosti rezanja navojev<\/i><\/em><\/p>\n

        \n
      1. Malo omejitev glede premera in dol\u017eine navoja.<\/li>\n
      2. Vse specifikacije je mogo\u010de izdelati z rezanimi navoji.<\/li>\n<\/ol>\n
