Monga chinthu chofunikira pamalumikizidwe amakina, kusankha magawo a fasteners ndikofunikira kuti zitsimikizire kukhazikika ndi chitetezo cha kulumikizanako.
1. Dzina lazogulitsa (Mulingo)
Dzina lachinthu cha fastener limalumikizidwa mwachindunji ndi kapangidwe kake komanso momwe amagwiritsidwira ntchito. Kwa zomangira zomwe zimagwirizana ndi milingo yeniyeni, kulemba nambala yokhazikika kumatha kuwonetsa bwino momwe amapangidwira komanso momwe amagwirira ntchito. Popanda miyezo yomveka bwino, zigawo zosagwirizana (zigawo zosagwirizana) zimafuna zojambula zatsatanetsatane kuti zisonyeze miyeso ndi mawonekedwe awo.
2. Mafotokozedwe
Mafotokozedwe a zomangira nthawi zambiri amakhala ndi magawo awiri: kutalika kwa ulusi ndi kutalika kwa screw. Machitidwe a metric ndi America ndi machitidwe awiri akuluakulu a ndondomeko. Zomangira za metric monga M4-0.7x8, pomwe M4 imayimira ulusi wakunja wa 4mm, 0.7 imayimira phula, ndipo 8 imayimira kutalika kwa screw. Zomangira zaku America monga 6 # -32 * 3/8, pomwe 6 # imayimira kukula kwa ulusi, 32 imayimira kuchuluka kwa ulusi pa inchi imodzi yautali wa ulusi, ndipo 3/8 ndi kutalika kwa screw.
3. Zinthu
Zida zomangira zimatsimikizira mphamvu zawo, kukana kwa dzimbiri, komanso moyo wautumiki. Zida zodziwika bwino zimaphatikizapo chitsulo cha carbon, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, mkuwa, aluminiyamu, ndi zina zotero. Chitsulo cha carbon chingagawidwe kukhala chitsulo chochepa cha carbon, sing'anga mpweya wa carbon, high carbon steel, ndi alloy steel. Ndikofunikira kusankha zinthu zoyenera kutengera momwe mungagwiritsire ntchito komanso momwe mungagwiritsire ntchito.
4. Mphamvu mlingo
Kwa zomangira zitsulo za kaboni, kalasi yamphamvu imawonetsa mphamvu zawo zolimba komanso mphamvu zokolola. Milingo wamba monga 4.8, 5.8, 6.8, 8.8, 10.9, 12.9, etc. High mphamvu zomangira, monga mankhwala a kalasi 8.8 kapena pamwamba, kawirikawiri amafuna kuzimitsa ndi tempering kutentha mankhwala kusintha makina awo katundu.
5. Chithandizo chapamwamba
Thandizo lapamwamba limapangidwa makamaka kukulitsa kukana kwa dzimbiri ndi kukongola kwa zomangira. Njira zodziwikiratu zimaphatikizira kuda, galvanizing (monga buluu ndi zinki zoyera, zinki zoyera, ndi zina), plating yamkuwa, nickel plating, chrome plating, ndi zina zambiri. moyo utumiki wa fasteners.
Mwachidule, posankha zomangira, ndikofunikira kuganizira mozama zinthu monga dzina lachinthu (muyezo), mawonekedwe, zida, mphamvu, ndi chithandizo chapamwamba kuti zitsimikizire kuti zikukwaniritsa zofunikira zogwiritsidwa ntchito ndikuchita bwino komanso moyo wautali.
