gulu
The otentha adagulung'undisa nthiti zitsulo bala amagawidwa m'magulu atatu: HRB335 (kalasi yakale ndi 20MnSi), kalasi yachitatu HRB400 (kalasi yakale ndi 20MnSiV, 20MnSiNb, 20Mnti), ndi kalasi zinayi HRB500.
Pali njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri pakulimbitsa mipiringidzo:imodzi ndikuyika molingana ndi mawonekedwe a geometric, ndipo ina ndikuyika m'magulu kapena kugawa molingana ndi mawonekedwe amipiringidzo yopingasa ndi matayala a mipiringidzo.Mtundu wa II. Gululi limawonetsa makamaka kukakamiza kolimbitsa.
Chachiwiri ndi molingana ndi kagawo ka magwiridwe antchito (kalasi), monga momwe akugwiritsidwira ntchito mdziko langa, rebar ndi (GB1499.2-2007) waya ndi 1499.1-2008), ndipo rebar imagawidwa 3 molingana ndi giredi yamphamvu (zokolola zokolola / mphamvu zolimba).Gulu;mu Japanese Industrial Standard (JI SG3112), mipiringidzo yachitsulo imagawidwa m'magulu a 5 malinga ndi katundu wawo wonse;mu British Standard (BS4461), magiredi angapo a mayeso azitsulo zazitsulo amatchulidwanso.Kuphatikiza apo, mipiringidzo yachitsulo imathanso kugawidwa ndikugwiritsa ntchito, monga zitsulo wamba zopangira konkriti yolimbitsa ndi zitsulo zotenthetsera kutentha kwa konkire yolimba yolimba.
mbali
1) M'mimba mwake mwadzina ndi m'mimba mwake analimbikitsa
Mipiringidzo yachitsulo mwadzina imayambira 6 mpaka 50mm, ndipo muyezo wovomerezeka wazitsulo zazitsulo ndi 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, ndi 50mm.
2) Kupatuka kovomerezeka kwa mawonekedwe apamwamba ndi kukula kwa nthiti zachitsulo
Mfundo zopangira mipiringidzo yachitsulo ya ribbed ziyenera kukwaniritsa izi:
Ngodya β pakati pa nthiti yodutsa ndi chitsulo cha bar axis siyenera kuchepera madigiri 45.Pamene mbali yophatikizidwayo siili yaikulu kuposa madigiri a 70, mayendedwe azitsulo zodutsa mbali zonse zazitsulo zazitsulo ziyenera kukhala zosiyana;
Kutalikirana mwadzina L kwa mipiringidzo yodutsa sikuyenera kupitilira 0.7 kuchulukitsa mwadzina kwa mipiringidzo;
Ngodya α pakati pa mbali ya nthiti yodutsa ndi pamwamba pazitsulo zazitsulo siziyenera kukhala zosachepera madigiri 45;
Kuchuluka kwa mipata (kuphatikiza m'lifupi mwake nthiti zazitali) kumapeto kwa nthiti zopingasa mbali zonse zoyandikana ndi chitsulo chachitsulo sichiyenera kukhala chachikulu kuposa 20% ya gawo lodziwika lazitsulo;
Pamene m'mimba mwake mwadzina wa zitsulo kapamwamba si oposa 12mm, wachibale nthiti m'dera sayenera kukhala zosakwana 0,055;pamene m'mimba mwake mwadzina ndi 14mm ndi 16mm, nthiti wachibale sayenera kukhala osachepera 0.060;pamene m'mimba mwake mwadzina ndi wamkulu kuposa 16mm, nthiti wachibale sayenera kukhala osachepera 0.065.Onani Zakumapeto C kuti muwerenge za dera la nthiti.
Mipiringidzo yachitsulo yokhala ndi nthiti nthawi zambiri imakhala ndi mipiringidzo yotalika, komanso palinso yopanda mipiringidzo yayitali;
3) Kutalika ndi kupatuka kololedwa
Mmodzi.kutalika
Mipiringidzo yachitsulo nthawi zambiri imaperekedwa muutali wokhazikika, ndipo kutalika kwake koyenera kumayenera kuwonetsedwa mu mgwirizano;
Mipiringidzo yachitsulo ikhoza kuperekedwa mu mipukutu, mpukutu uliwonse uyenera kukhala chitsulo chimodzi, ndipo 5% ya chiwerengero cha mipukutu pa batch (zosakwana mipukutu iwiri ndi mipiringidzo iwiri) imakhala ndi mipiringidzo iwiri yachitsulo.Kulemera kwa disk ndi kukula kwa disk kumatsimikiziridwa kupyolera mu zokambirana pakati pa wogulitsa ndi wogula.
b.Kulekerera kwautali
Pamene kutalika kokhazikika kumaperekedwa, kupatuka kovomerezeka kwa kutalika kwa chitsulo chachitsulo sikuposa ± 25mm;
Pamene kutalika kochepa kumafunika, kupatuka ndi +50mm;
Pamene kutalika kwakukulu kumafunika, kupatukako ndi -50mm.
c.Kupindika ndi malekezero
Mapeto azitsulo zachitsulo ayenera kudulidwa molunjika, ndipo kusinthika kwapafupi sikudzakhudza ntchito
