Ho ea ka mekhoa e fapaneng ea ho etsa mokhoa oa ho etsa, li-fasteners li ka aroloa ka li-fasteners tse ferekanyang (joalo ka li-rivets tsa aluminium alloy), li-fasteners tse sehang (tse kang ho itšeha ka li-hexagonal le ho sebetsana le li-screws le linate) le ho seha li-nodular fasteners (joalo ka li-screws tse ngata, liboutu le liboutu tse phahameng). Ho halefisa ho ka aroloa ka ho halefisa ho bata le ho chesa (mofuthu).
7. Ho khetholla ho ea ka boemo ba ho qetela ba phekolo ea holim'a metsi
Ho ea ka phapang ea boemo ba ho qetela ba phekolo ea holim'a metsi, li-fasteners li arotsoe ka li-fasteners tse sa phekoloeng le li-fasteners tse tšoaroang. Li-fasteners tse sa phekoleheng ka kakaretso ha li fumane phekolo e khethehileng, 'me li ka kenngoa polokelong le ho romelloa ka mor'a ho hloekisa ho hlokahalang ka mor'a ho fetisa mekhoa ea ho bopa le ea mocheso. Phekolo ea li-fasteners, mofuta oa kalafo ea holim'a metsi e hlalositsoe ka botlalo khaolong ea kalafo ea fasteners. Ka mor'a hore li-fasteners tse nang le zinki li bitsoa li-fasteners tse nang le zinc, ka mor'a hore li-fasteners tse entsoeng ka cadmium li bitsoa cadmium-plated fasteners, ka mor'a hore oxidation ea fasteners e bitsoa oxidation ea fasteners. Joalo joalo.
8. Ho arola ho latela matla
Ho ea ka matla a fapaneng, li-fasteners li arotsoe ka li-fasteners tse tlaase-tlaase, li-fasteners tse matla haholo, li-fasteners tse matla le li-ultra-high-power fasteners 4 lihlopha. Indasteri ea li-fastener e tloaetse thepa ea mochini ea sehlopha se ka tlase ho 8.8 kapa matla a ka tlase ho 800MPa a tsejoang e le li-fasteners tse matla a tlase, thepa ea mochini ea sehlopha se lipakeng tsa 8.8 le 12.9 kapa matla a matla a pakeng tsa 800MPa-1200MPa pakeng tsa li-fasteners tse phahameng tse tsejoang e le li-fasteners tse phahameng ka lebitso. 1200MPa-1500MPa lipakeng tsa li-fasteners tse tsejoang ka hore ke li-fasteners tse matla a phahameng, matla a matla a holimo ho feta 1500MPa fasteners a tsejoang ka hore ke li-ultra-high-strength fasteners.
9.Case mofuta oa mosebetsi o boima classification
Ho ea ka phapang ea mofuta oa mojaro o sebetsang, li-fasteners li arotsoe ka mekhahlelo e 'meli: mofuta oa tensile le oa ho kuta. Li-fasteners tsa tensile haholo-holo li tlas'a moroalo o thata kapa oa ho hula-shear composite load; li-fasteners tsa ho kuta li atisa ho kuta. Tensile fasteners le fasteners kuta ka lebitso la molamu bophara mamello le threaded fasteners khoele bolelele, joalo-joalo Ho na le ba bang ba diphapano.
10. Ho arola ho latela litlhoko tsa ts'ebetso ea kopano
Ho ea ka liphapang tsa litlhoko tsa ts'ebetso ea kopano, li-fasteners li arotsoe ka li-fasteners tse nang le mahlakoreng a le mong (tse tsejoang hape e le li-blind connections) le li-fasteners tse mahlakoreng a mabeli. Li-fasteners tsa mahlakoreng a le mong li hloka feela ho hokahanngoa ka lehlakoreng le le leng la ts'ebetso li ka phethoa kopano.
11. Ho aroloa ho latela hore na kopano e ka qhaqhoa kapa che
Ho ea ka hore na kopano e ka qhaqhoa kapa che, li-fasteners li arotsoe ka li-fasteners tse tlosoang le li-fasteners tse sa tlosoeng. Li-fasteners tse tlosoang ke li-fasteners tse hlokang ho qhaqhoa 'me li ka qhaqhoa ha li sebelisoa ka mor'a kopano, tse kang li-bolts, screws, linate tse tloaelehileng, li-washer joalo-joalo. Li-fasteners tse sa tsitsang li bua ka kopano, ha ho sebelisoa ts'ebetso le li-fasteners tsa eona ha li qhekelloe; e tlameha ho qhaqhoa, li-fasteners tsa mofuta ona li ka boela tsa qhaqhoa, empa hangata li lebisa ho li-fasteners kapa li-link tsa tsamaiso li ke ke tsa sebelisoa hape ka lebaka la ho senyeha ha li-fasteners, ho akarelletsa le mefuta e fapaneng ea li-rivets, li-bolts tse phahameng tsa ho notlela, li-studs, linate tse phahameng tsa ho notlela, joalo-joalo.
12. E arotsoe ka litaba tsa tekheniki
Ho ea ka litaba tse fapaneng tsa tekheniki, li-fasteners li arotsoe ka maemo a 3: a tlase, a bohareng le a holimo. Indasteri ea li-fastener e tloaetse ho nepahala ho phahameng ka ho fetesisa ha e phahametse 7, matla a ka tlase ho 800MPa ea li-fasteners tsa sepheo se akaretsang tse bitsoang li-fasteners tse tlase, li-fasteners tse joalo ha li thata haholo ka botekgeniki, litaba tsa thekenoloji tse tlase le boleng bo tlase; e tla ba palo e phahameng ka ho fetisisa ea ho tšoaea 6 kapa 5, matla pakeng tsa 800MPa-1200MPa, thepa e na le litlhoko tse itseng tsa li-fasteners tse tsejoang e le li-fasteners tse bohareng, tse nang le bothata bo itseng ba tekheniki, li-fasteners le litaba tse ling tsa theknoloji. Li-fasteners li na le bothata bo itseng ba tekheniki, litaba tse itseng tsa tekheniki le boleng bo ekelitsoeng; boleng bo phahameng ka ho fetisisa ba ho tšoaea ba maemo a fetang 5, kapa matla a fetang 1200MPa, kapa litlhoko tse khahlanong le mokhathala, kapa litlhoko tse khahlanong le mocheso, kapa litlhoko tse khethehileng tsa anticorrosion le lubrication, tse kang li-fasteners tse khethehileng tse tsejoang e le li-fasteners tse phahameng, li-fasteners tse joalo li thata ka botekgeniki, li na le litaba tse phahameng tsa tekheniki le boleng bo eketsehileng.
Ho na le litsela tse ling tse ngata tsa ho arola li-fasteners, tse kang ho arola ho ea ka sebopeho sa hlooho ea li-fasteners, joalo-joalo, hore li se ke tsa thathamisoa. Ka lisebelisoa, litsamaiso tsa lisebelisoa le mekhoa ea ts'ebetso joalo-joalo li tsoela pele ho nchafatsa, batho ba tla ipapisa le tlhoko ea ho beha mekhoa e mecha ea ho hlophisa li-fasteners.
