HG/T 20613 Ulusi wathunthu
Stud yodzaza ndi ulusi: ndi mtundu wa kugawa kwa ulusi pamtunda wonse wa bawuti, ndipo mabawuti amitu iwiri kumbali zonse ziwiri ndi chiyambi cha ulusi, pakati amasunga gawo lopanda ulusi, nsonga ziwiri za ulusi womwewo ukhoza kutembenuzidwanso. Bawuti yonse imakhala yolumikizidwa, bawuti iyi ndi yokwera kuposa ma bawuti amutu wa hexagonal komanso mphamvu zomangirira mutu wapawiri, kukweza kuchuluka kwa ntchito, ma bawuti a hexagonal ndi ma studs apamutu awiri ndi mabawuti amakalasi amalonda, pogwiritsa ntchito mulingo wantchito womwe wawonetsedwa. Ndipo zipilala za ulusi wathunthu ndi ma bawuti apadera, kugwiritsa ntchito magiredi azinthu, kugwiritsa ntchito makhazikitsidwe amankhwala, kugwiritsa ntchito m'malo mwazinthu ziyenera kutsimikiziridwa ndi kapangidwe ka HG/T20613-2009 chitsulo chitoliro chachitsulo chokhala ndi ulusi wambiri wamba M10, M12, M16, M20, M3 × 3, M3, M3, M2 M39 × 3, M45 × 3 M52 × 4, M56 × 4, pamwamba akhoza kuda, Dacromet, otentha-kuviika kanasonkhezereka, Teflon ndi zina zotero.
Kugwiritsiridwa ntchito kwa ma studs a ulusi wathunthu kumawonekera makamaka muzinthu izi:
1. Kulumikiza ndi kumangirira: Ntchito yaikulu ya stud yopangidwa mokwanira ndi kugwirizanitsa ndi kulumikiza zigawo ziwiri kapena zambiri. Imazindikira kugwirizana kolimba pakati pa zigawozi kupyolera mu kupukuta kwa ulusi, kuwalepheretsa kumasula kapena kupatukana. Kulumikizana kotereku sikophweka komanso kodalirika, komanso kosavuta kusokoneza, kulola kuti m'malo mophweka kapena kukonzanso magawo pakufunika.
2. Kutumiza mphamvu: Zingwe zomangika mokwanira zimatha kutumiza mphamvu kuchokera kuchigawo chimodzi kupita ku china. Mu chipangizo chamakina kapena kapangidwe kake, kusamutsa mphamvu uku ndikofunikira kuti zitsimikizire kukhazikika ndi magwiridwe antchito a dongosolo lonse. Mphamvu zazikulu ndi kudalirika kwa ma studs opangidwa mokwanira zimawalola kulimbana ndi mphamvu zazikulu ndi zipsinjo kuti zitsimikizire kugwira ntchito kwabwino kwa dongosolo lonse.
3. Kusintha ndi Maonekedwe: Chifukwa stud yolumikizidwa kwathunthu ili ndi gawo lalitali la ulusi, imatha kugwiritsidwa ntchito ngati membala wosintha. Pozungulira stud, malo ogwirizana pakati pa magawo awiri ogwirizanitsa akhoza kusinthidwa, motero kuzindikira kusinthidwa kolondola ndi kuyika kwa zipangizo kapena mapangidwe. Kusintha kumeneku kumapangitsa kuti ma studs okhala ndi ulusi wathunthu akhale othandiza pamapulogalamu omwe amafunikira kuwongolera bwino kwagawo kapena ngodya.
4. Msonkhano Wosavuta: Mapangidwe azitsulo zonse zimapangitsa kuti msonkhano ukhale wosavuta kusiyana ndi zomangira zina. Kutalikirapo kwa ulusi wa stud kumapangitsa kuti kukhale kosavuta kulumikiza ndi kufinya mu dzenje, kuchepetsa vuto la msonkhano ndi zolakwika. Izi zimathandiza kukulitsa luso la msonkhano komanso kuchepetsa ndalama zopangira.
