Likahare tsa tlhahlobo ea li-fasteners

Li-fasteners, tse tsejoang hape e le likarolo tse tloaelehileng 'marakeng, ke lentsoe le akaretsang bakeng sa mofuta oa likarolo tsa mochini tse sebelisetsoang ho hokahanya likarolo tse peli kapa ho feta (kapa likarolo) ka mokhoa o sireletsehileng. Li bitsoa "limithara tsa indasteri" 'me li na le lisebelisoa tse pharaletseng likarolong tse kang mechine, lisebelisoa, likoloi, likepe, literene, marokho, mehaho, mehaho, lisebelisoa, lisebelisoa, lisebelisoa le lisebelisoa.

Lintho tsa tlhahlobo ea ts'ebetso ea li-fasteners li kenyelletsa: boholo, sebopeho sa lik'hemik'hale, tlhahlobo e sa senyeheng, thepa ea mochini e kenyelletsang khokahanyo ea bolt ea torsion, ho tiisa matla a axial, tensile (matla a chai, matla a thata), ho thatafala le tlhahlobo ea thepa ea mochini oa li-fasteners tsa sebopeho sa tšepe.

Limaraka tsa tšebetso ealiboutu bakeng sa sebopeho sa tšepekopanya ke 4.6, 4.8, 6.8, 8.8,10.9, 12,9, joalo-joalo Liboutu tsa sehlopha sa 8.8 le ho ea holimo li tšehetsoa ke tšepe e nang le carbon alloy e tlaase kapa tšepe e bohareng ea carbon le mocheso, tseo ka kakaretso li bitsoang.liboutu tse matla haholo, ’me tse ling ka tloaelo li bitsoa liboutu tse tloaelehileng

Likahare tsa tlhahlobo ea li-fasteners

1. Litekanyo tsa ponahalo: khoele ea go/no go gauge, ho ba mahoashe holimo, litekanyo tse fapa-fapaneng tse kang bophara bo boholo, bophara ba sekontiri, bophara bo bonyenyane, angle ea profil, molumo, joalo-joalo.

2. Teko ea ts'ebetso ea mochini: teko ea ho ts'oara, teko ea ho ts'oara, teko ea ho thatafala, teko ea ho tsitsa, teko ea phello, teko ea boima ba wedge, teko ea ho kuta, teko ea mokhathala, ts'ebetso ea ho notlela, torque coefficient, tightening axial force, friction coefficient, anti slip coefficient, screwability test, gasket elasticity, toughness test, hydrogen embrittlement test, joalo-joalo.

3. Tlhahlobo ea sebopeho sa lik'hemik'hale: fastener chemical composition analysis, fastener metal material grade identification, joalo-joalo.

4. Tlhahlobo ea metallographic: microstructure, botebo ba lera la decarburization, botebo ba lera la carburization, tekanyo ea boholo ba lijo-thollo, likahare tse kenyelletsoeng, macrostructure, joalo-joalo.

5. Tlhahlobo ea ho hlōleha: tlhahlobo ea ho phatloha, tlhahlobo ea fracture, tlhahlobo ea fracture, joalo-joalo.

6. Teko ea ho hanyetsa kutu: tlhahlobo ea spray ea letsoai e sa nke lehlakore (NSS), tlhahlobo ea acetate spray (AASS), tlhahlobo ea koporo e potlakileng ea acetate spray (CASS)
