Mechaninio tvirtinimo elemento sriegiai, neatsi\u017evelgiant \u012f tai, ar tai a\u00a0var\u017etas su galvute<\/u>,\u00a0strypas<\/u>, arba\u00a0parduotuv\u0117 viduje<\/u>, gali b\u016bti gaminami pjaustant arba valcuojant.

Valcuoti si\u016blai<\/b><\/strong><\/h3>\n

Ritininis sriegimas yra procesas, kurio metu plienas i\u0161spaud\u017eiamas, kad b\u016bt\u0173 suformuota tvirtinimo detal\u0117s sriegin\u0117 dalis, o ne pa\u0161alinamas, kaip sriegimo metu. \u0160iame procese var\u017etas gaminamas i\u0161 suma\u017einto skersmens apvalaus strypo. Pavyzd\u017eiui, 1 colio skersmens var\u017etas gaminamas i\u0161 0,912 colio skersmens apvalaus strypo. \u0160i \u201e\u017eingsnio skersmens\u201c med\u017eiaga yra ma\u017edaug vidurio ta\u0161kas tarp did\u017eiausio sriegi\u0173 skersmens (smaili\u0173) ir ma\u017eesnio skersmens (sl\u0117ni\u0173). Var\u017etas \u201ei\u0161sukamas\u201c per sriegini\u0173 \u0161tamp\u0173 rinkin\u012f, kuris i\u0161stumia plien\u0105 ir suformuoja sriegius. Galutinis rezultatas \u2013 tvirtinimo detal\u0117 su viso 1 colio skersmens sriegine dalimi, bet suma\u017eintu korpuso skersmeniu (.912). Ritininis sriegimas yra itin efektyvus procesas, d\u0117l kurio da\u017enai sutaupoma daug i\u0161laid\u0173. Tod\u0117l, kai tik \u012fmanoma, \u201ePortland Bolt\u201c suvynios sriegius.<\/p>\n

 <\/p>\n

Techni\u0161kai bet kokios specifikacijos, i\u0161skyrus A325 ir A490 konstrukcinius var\u017etus, gali b\u016bti gaminami su suma\u017eintu korpusu ir valcuotais sriegiais.<\/p>\n

 <\/p>\n

Var\u017etas su suma\u017eintu korpusu bus silpnesnis nei var\u017etas su viso dyd\u017eio korpusu.<\/p>\n

Silpniausia bet kurio mechaninio tvirtinimo detal\u0117 yra nedidelis sriegi\u0173 skersmuo. Kadangi nupjauto sriegio ir valcuoto sriegio tvirtinimo detal\u0117s sriegio matmenys yra vienodi, stiprumas visi\u0161kai nesiskiria. I\u0161 tikr\u0173j\u0173 b\u016bt\u0173 galima gin\u010dytis, kad d\u0117l sukiet\u0117jimo, kuris vyksta sriegimo \u012f ritin\u012f proces\u0105, tvirtinimo detal\u0117 su valcuotais si\u016blais gali tapti tvirtesn\u0117. Be to, nupjautas sriegimas nutraukia nat\u016brali\u0105 apvalaus strypo gr\u016bd\u0117tumo strukt\u016br\u0105, o ritininis sriegimas j\u0105 reformuoja. V\u0117lgi galima teigti, kad \u012fpjovus apvalaus strypo gr\u016bdelius sriegimo metu, gali susidaryti si\u016blai, kuri\u0173 strukt\u016brinis vientisumas yra ma\u017eesnis nei dalis, kuri buvo \u012fsriegta ritininiu b\u016bdu.<\/p>\n

Ritininio sriegimo privalumai<\/i><\/em><\/p>\n

    \n
  1. \u017dymiai trumpesnis darbo laikas rei\u0161kia ma\u017eesnes i\u0161laidas.<\/li>\n
  2. Kadangi ritininio srieginio var\u017eto korpuso skersmuo yra ma\u017eesnis, jis sveria ma\u017eiau nei pilnas korpusas. \u0160is svorio suma\u017einimas suma\u017eina plieno, cinkavimo, terminio apdorojimo, dengimo, gabenimo ir visas kitas su tvirtinimo detale susijusias i\u0161laidas, kurios priklauso nuo svorio.<\/li>\n
  3. Apdorojant \u0161altu b\u016bdu, si\u016blai tampa atsparesni pa\u017eeidimams tvarkymo metu.<\/li>\n
  4. Valcuoti si\u016blai da\u017enai b\u016bna lygesni d\u0117l valcavimo operacijos poliravimo efekto.<\/li>\n<\/ol>\n

      Nupjautas sriegis yra procesas, kurio metu plienas nupjaunamas arba fizi\u0161kai pa\u0161alinamas i\u0161 apvalaus plieno strypo, kad b\u016bt\u0173 suformuoti si\u016blai. Pavyzd\u017eiui, 1 colio skersmens var\u017etas gaminamas \u012fpjaunant sriegius \u012f viso 1 colio skersmens var\u017eto korpus\u0105.<\/p>\n
