Hex Head, Socket Head, le Flange Bolts: Likarolo tsa Moqapi, Melemo, le Likopo
Moralong oa mochini le tlhahisong, ho bohlokoa ho khetha mofuta o nepahetseng oa fasteners ho netefatsa bots'epehi ba sebopeho, bonolo ba kopano, le ts'epahalo ea nako e telele. Har'a li-fasteners tse sebelisoang ka ho fetisisa ke liboutu tsa hlooho ea sokete (hex ea ka hare).,liboutu tsa hlooho ea hex (hex ea kantle).,le liboutu tsa flange. Ha re hlalose meralo ea bona, melemo le lits'ebetso ho u thusa ho khetha tharollo e nepahetseng bakeng sa merero ea hau.
1. Socket Head Bolts (Internal Hex)
Li-socket head bolts li entsoe ka sekhahla sa hexagonal ka har'a hlooho ea bolt, e hlokang wrench ea Allen (senotlolo sa hex) bakeng sa ho kenya. Moralo ona o lumella hlooho ea bolt hore e lule e tsitsitse kapa ka tlase ho sebaka sa mosebetsi, e leng se etsang hore e be se loketseng bakeng sa lits'ebetso moo mathata a sebaka kapa maikutlo a botle a leng bohlokoa. Sokete e tebileng ea hex e ka hare e fana ka tšireletso e sireletsehileng bakeng sa ts'ebeliso ea torque, e fokotsa kotsi ea ho thella ha sesebelisoa le ho nolofalletsa matla a ho tiisa ha a bapisoa le li-fasteners tsa setso. Hangata liboutu tsena li etsoa ka tšepe e thata ea k'habone kapa tšepe e sa hloekang, e netefatsang botsitso lipakeng tsa matla le ho hanyetsa ho bola.
Monyetla o ka sehloohong oa li-socket head bolts o boemong ba bona ba ho boloka sebaka le bokhoni ba ho sebetsana le torque e phahameng ntle le ho hlobola. Sena se li etsa tsa bohlokoa haholo mochining o nepahetseng, lienjineri tsa makoloi, le lits'ebetso tse koaletsoeng moo lihlooho tsa li-fasteners tse hlahelletseng li ka sitisang likarolo tse tsamaeang kapa tsa senya polokeho. Mohlala, likopanong tsa mochini oa CNC, liboutu tsa sokete li sireletsa likarolo ka thata ha li ntse li boloka sebaka se boreleli ho thibela ho ts'oaroa. Litekanyo tsa bona tse emeng, tse laoloang ke GB/T 70.1 (Chaena) le ISO 4762 (litekanyetso tsa machaba), li netefatsa tšebelisano ho liindasteri tsa lefats'e.
2. Hex Head Bolts (External Hex)
Liboutu tsa hlooho tsa Hex li na le hlooho ea khale ea hexagonal e etselitsoeng ho sebelisoa ka li-wrenches tse bulehileng, li-wrenches tsa mabokose kapa lisebelisoa tsa sokete. Moralo oa bona o otlolohileng, o tiileng o etelletsa pele boiketlo ba ho kenya le matla a holimo, e leng se etsang hore e be khetho e akaretsang bakeng sa lits'ebetso tse boima. Sebopeho sa hex se ka ntle se fana ka sebaka se lekaneng sa ho sebelisa lisebelisoa, se lumellang mechini ho sebelisa torque ea bohlokoa le maemong a thata. Liboutu tsena hangata li hlahisoa ka limaraka ho tloha ho 4.8 ho isa ho 12.9, ho ipapisitse le litlhoko tse fapaneng tsa matla.
Ho nolofatsa le ho baballa litšenyehelo tsa liboutu tsa hlooho tsa hex li tiisitse karolo ea tsona ho aheng, ho sebetsa ka tšepe le mecheng e akaretsang. Mohlala, kahong ea borokho, liboutu tsa hlooho tsa boemo bo holimo tsa hex (mohlala, Kereiti ea 8.8 kapa 10.9) li sebelisoa ho kopanya maballo a tšepe, ho matlafatsa bokhoni ba tsona ba ho mamella meroalo e matla le ho thothomela. Maemo a kang GB/T 5782 (Chaena) le ISO 4014 (machabeng) a netefatsa ho ts'oana ha likhoele le litekanyo tsa hlooho, ho tsamaisa tlhahiso ea bongata le ho fapanyetsana. Le ha ba se na monyetla oa boemo bo tlase ba li-socket heads, ts'ebelisano ea bona e atileng ea lisebelisoa le ts'epahalo e matsutla li ba etsa setsi sa mantlha mererong ea boenjiniere ba indasteri le ea sechaba.
3. Flange Bolts
Li-flange bolts li kopanya molaleng o kang oa washer (flange) ka ho toba ka tlas'a hlooho ea bolt, ho felisa tlhokahalo ea li-washer tse arohaneng. Flange ena e fana ka matla a ho tiisa holim'a sebaka se pharaletseng, e fokotsa khatello ea metsi le ho fokotsa tšenyo ea thepa e bonolo joalo ka polasetiki kapa liphanele tse kopaneng. Mefuta e fapaneng e kenyelletsa li-flanges tse "lomang" holim'a bokaholimo ho thibela ho thothomela, le li-flange tse boreleli bakeng sa lits'ebetso tse hlokang ho qhaqha khafetsa. Hangata liboutu tsena li koahetsoe ka zinki kapa Dacromet ho matlafatsa khanyetso ea kutu maemong a thata.
Monyetla o ka sehloohong oa li-bolts tsa flange ke ts'ebetso ea bona e 'meli-ho kopanya ho tiisa le ho fana ka thepa ka karolo e le' ngoe. Moralo ona o bohlokoa haholo tlhahisong ea likoloi, moo liboutu tsa serrated tsa flange li sireletsang likarolo tsa enjene tse lulang li sisinyeha. Ka mokhoa o ts'oanang, lits'ebetsong tsa HVAC, liboutu tse boreleli li nolofatsa kopano ka ho fokotsa palo ea likarolo ha li ntse li boloka litiiso tse sa luleng. Maemo a kang GB/T 5787 le GB/T 16674 (Chaena) a hlakisa litekanyo le mamello, ho netefatsa ts'ebetso e tsitsitseng ho pholletsa le lihlopha. Thepa ea bona ea ho ikamahanya le maemo le e thibelang ho lokoloha e ba etsa khetho e holimo bakeng sa liindasteri tse etelletsang pele katleho le ho tšoarella.
Mokhoa oa ho khetha Fastener e nepahetseng
• Lithibelo tsa Sekhoba: Khetha liboutu tsa sokete libakeng tse thata kapa tse khaohileng.
• Litlhoko tsa Torque: Sebelisa liboutu tsa hlooho ea hex bakeng sa lits'ebetso tsa torque e phahameng tse nang le tumello e lekaneng.
• Meroalo ea Tšisinyeho / Tšusumetso: Beha pele liboutu tsa flange tse nang le li-collar tse serrated.
• Litlhoko tsa Aesthetic: Lihlooho tsa li-socket li fana ka qetello e ntle bakeng sa likopano tse bonahalang.
