I-DIN7991 Black Hex Socket Countersunk Head Cap Bolt
Iyini i-hex socket countersunk head cap bolt?
Ama-Countersunk bolt ayizibophelelo zebhawodi ezinekhanda eliyisicaba ezinesokhethi ye-hex ekhanda.Amabhawodi e-Countersunk anentamo yohlobo lwe-cone enekhanda eliyisicaba, ama-socket bolts e-hex socket bolts, ama-bolts we-flat head socket cap bolts amanye ama-alias ama-hex head bolts.Ubukhulu bamabhawodi e-Countersunk buchazwa kubo bobabili osayizi bemethrikhi kanye ne-imperials ngephimbo kazwelonke ehlangene ye-coarse (UNC), iphimbo elihlanjululwe (UNF), i-fixed pitch(UN) kanye nephrofayili ye-ISO metric thread.Lokhu kukhiqizwa kuzo zonke izigaba zezinto ezibonakalayo kanye nokucaciswa kwe-ASTM kodwa kuvame ukukhiqizwa ngaphansi kwe-F568 grade 8.8, 10.9,12.9, F593, BS, EN, ISO3506-1, SS304, SS316,2205, njll.
Izinhlelo zokusebenza
Ngaphezulu kwembobo efakwe engxenyeni yokuxhuma, isokhethi eyindilinga eyindilinga engu-90-degree iyacutshungulwa, futhi ikhanda lesikulufu somshini oyisicaba likulesi sokhethi esiyindilinga, esigubhayo ngobuso besiqeshana sokuxhuma.Izikulufu zomshini oyisicaba zibuye zisetshenziswe kwezinye izikhathi ngezikulufa zomshini wekhanda eliyindilinga.Lolu hlobo lwesikulufu luhle kakhulu futhi lusetshenziswa ezindaweni lapho indawo engaphezulu ingavumela ukuphuma kancane.
Iningi le-hex socket countersunk head cap bolts lisetshenziswa ezindaweni lapho ingaphezulu lengxenye lingakwazi ukuphakanyiswa ngemva kokufakwa.Kunezinhlobo ezimbili zezingxenye okufanele ziboshwe.Ubukhulu bekhanda, ngemva kokuba isikulufu siqinisiwe, ingxenye yentambo yesikulufu namanje ayifaki imbobo enentambo.Kulokhu, isikulufu sekhanda esiphikisayo singaqiniswa ngokuqinisekile.
Ikhoni yekhanda lesikulufu sekhanda elishisiwe ine-engeli yekhoni engu-90 °.Ngokuvamile, i-engeli ephezulu ye-drill bit esanda kuthengwa ingu-118 ° -120 °.Ezinye izisebenzi ezingaqeqeshiwe aziwazi lo mehluko we-engeli, futhi ngokuvamile zisebenzisa i-120 ° drill Reaming, okuholela ekutheni izikulufu zekhanda ze-countersunk azicindezelwe lapho kuqiniswa izikulufu zekhanda ezicwile, kodwa kube umugqa ongezansi kwekhanda lesikulufu, okuyi-screw. esinye sezizathu zokuthi kungani okuthiwa i-hex socket countersunk head cap bolts ayikwazi ukubamba iqine.
Izinyathelo zokuqapha ngesikhathi sokusetshenziswa
1.I-taper yembobo yokubuyisela kabusha kufanele ibe ngu-90 °.Ukuze uqinisekise, kungcono ukuba ngaphansi kuka-90 °, hhayi ngaphezu kuka-90 °.Leli iqhinga eliyisihluthulelo.
2. Uma ubukhulu beshidi lensimbi bungaphansi kobukhulu bekhanda lesikulufu sekhanda elishibilikayo, ungashintsha isikulufu esincane, noma ukhulise imbobo ibe mncane kunokwandisa imbobo ukuze ububanzi bembobo engezansi bube bukhulu. futhi ingxenye ayiqinile.
3. Uma kunezimbobo eziningi ze-hex isokhethi countersunk head cap bolt izimbobo engxenyeni, nembe kakhudlwana ngesikhathi machining.Uma i-drill isigwegwile, kunzima ukubona umhlangano, kodwa ingaqiniswa inqobo nje uma iphutha lincane, ngoba lapho isikulufu singaqini kakhulu Esikhulu (cishe singabi ngaphezu kuka-8mm), uma kunephutha ibanga lembobo, ikhanda le-screw lizokhubazeka ngenxa yokuphoqa lapho liqiniswa, noma lizoqiniswa.
