Liboutu tsa Hex

外六角螺栓

1.Mohopolo
Boutu e ka ntle ea hexagonal ke sesebelisoa sa tšepe, se tsejoang hape e le sekoti sa ka ntle sa hexagonal, screw ea kantle ea hexagonal kapa bolt e kantle ea hexagonal.

2.Kalafo ea holim'a metsi
Ts'ebetsong ea ho etsa liboutu, kalafo ea bokaholimo ke e 'ngoe ea likhokahano tsa bohlokoahali. E ka etsa hore bokaholimo ba bolt bo finyelle litlhoko tse itseng mme bo ntlafatse ho hanyetsa ha kutu, matla le botle ba eona.
Ho na le mefuta e mengata ea mekhoa ea kalafo ea holim'a liboutu, tse tloaelehileng ke tse latelang:
Galvanizing: Liboutu li qoelisoa ka har'a motsoako oa zinki, 'me zinki e koahetsoe ka holim'a lera la liboutu ka sekhahla ka karabelo ea electrochemical, e etsa hore e se ke ea bola le ho bola.
Hot-dip galvanizing: Ka mor'a hore liboutu li etsoe, li qoelisoa ka mokelikeli oa zinki o qhibilihisitsoeng, 'me lesela la zinki le thehoa ka holim'a lik'hemik'hale ho finyella liphello tse khahlanong le mafome, tse thibelang ho bola le tse ling.
Kalafo ea Blackening: Filimi e ntšo ea metal oxide e thehoa holim'a bolt ka karabelo ea lik'hemik'hale ho ntlafatsa ho hanyetsa ha eona.
Phekolo ea Phosphating: Inela boutu ka har'a tharollo ea phosphating ho etsa filimi ea phosphating holim'a metsi ho ntlafatsa ho hanyetsa ho bola ha eona.
Kalafo ea ho thatafatsa: Ka phekolo ea mocheso kapa ho fafatsa holim'a metsi, ho thehoa lera la ho roala ka thata e phahameng holim'a bolt ho ntlafatsa matla a eona le ho hanyetsa ho apara.
Tse ka holimo ke mekhoa e tloaelehileng ea phekolo ea bolt holim'a metsi. Mekhoa e fapaneng ea kalafo e lumellana le maemo le litlhoko tse fapaneng tsa ts'ebeliso. Ha ho etsoa phekolo ea holim'a bolt, e tlameha ho etsoa ho latela litekanyetso le litlhaloso tse lumellanang ho netefatsa hore liboutu tse tšoaroang li finyella litlhoko tse nepahetseng tsa tshebetso.

3. Ts'ebetso ea boemo
Leibole ea boemo ba ts'ebetso ea bolt e ka ntle ea hexagonal e na le likarolo tse peli tsa linomoro, tseo ka tatellano li emelang boleng ba matla a tensile le tekanyo ea tlhahiso ea thepa ea bolt.
Mohlala, bolt e nang le boemo ba ts'ebetso ea 4.6 e bolela:
a. Matla a ho sisinyeha ka lebitso a thepa ea bolt a fihla ho 400MPa;
b. Karolelano ea lihlahisoa-matla a thepa ea bolt ke 0,6;
c. Matla a tlhahiso ea tlhaho ea thepa ea bolt e fihla ho 400 × 0.6 = 240MPa boemo
Boemo ba ts'ebetso 10.9 liboutu tse matla a phahameng, kamora kalafo ea mocheso, li ka fihlela:
a. Matla a ho sisinyeha ka lebitso a thepa ea bolt a fihla ho 1000MPa;
b. Matla a tlhahiso ea tlhaho ea thepa ea bolt e fihla ho 1000×0.9=900MPa.

4. Phapang lipakeng tsa liboutu tse tloahelehileng tsa ka ntle tsa hexagonal le liboutu tse matla tse ka ntle tse nang le mahlakore a mabeli.
Liboutu tse tloaelehileng tsa hexagonal li ka sebelisoa hape, empa liboutu tse matla haholo li ke ke tsa sebelisoa hape.
Li-bolts tse matla ka kakaretso li entsoe ka tšepe ea matla a phahameng No. Bakeng sa mefuta ea likhohlano, sebelisa sekontiri sa torque ho sebelisa prestress e boletsoeng, 'me bakeng sa mefuta e nang le khatello, tlosa hlooho ea torx. Li-bolts tse tloaelehileng hangata li entsoe ka tšepe e tloaelehileng (Q235) 'me li hloka feela ho tiisoa.
Liboutu tse tloaelehileng ka kakaretso ke grade 4.4, grade 4.8, grade 5.6 and grade 8.8. Liboutu tse matla a holimo hangata ke grade 8.8 le grade 10.9, 'me kereiti ea 10.9 ke eona e atileng haholo.
Li-screw masoba tsa liboutu tse tloaelehileng ha se hakaalo hore li kholo ho feta tsa liboutu tse matla a phahameng. Ha e le hantle, masoba a tloaelehileng a bolt a batla a le manyenyane.
