DIN933 304 A2-70 Hexagonal Bolt
Cov Khoom Piav Qhia
Cov kev cai A-level yog: d ≤ 24mm thiab l ≤ 10d lossis l ≤ 150mm (qhov twg me dua); Cov kev cai rau Chav B yog: d> 24mm lossis l> 10d lossis l> 150mm (qhov twg me dua). Ntawm lawv, d sawv cev rau txoj kab uas hla ntawm xov, thiab l sawv cev rau qhov ntev ntawm lub ntsia hlau. Cov qib khoom sib txawv muaj cov nqi sib xws rau cov npoo sib txawv s, kab pheeb ces kaum e, tuab k, thiab kev kam rau siab ntev.
Cov xov dav dav ntawm DIN 933 bolts yog M3-M64, thiab cov qib ua tau zoo ntawm cov hlau carbon feem ntau yog 8.8 thiab 10.9. Thaum d ≤ 39mm, cov hlau tsis xeb feem ntau yog A2-50 / A2-70 / A4-70 / A4-80, uas tuaj yeem xa mus rau ISO 3506-1 lossis DIN 267-11.
Cov bolts ntawm tus qauv no feem ntau yog metric (xov ntxhib) thiab xov zoo, ntsuas hauv millimeters (mm). Qhov kam rau siab rau DIN 933 xov ntxhib yog 6g. Cov txheej txheem pleev xim uas siv ntau hauv khw suav nrog cov txheej dub, electroplating (xiav dawb zinc, daj zinc), thiab cov txheej hmoov zinc tsis electrolytic (GEO). Qhov kam rau siab ua ntej pleev xim feem ntau yog 6g/6H, thiab qhov kam rau siab tom qab galvanizing tuaj yeem hloov mus rau 6h/6G. Txawm li cas los xij, vim muaj kev cuam tshuam ntawm qhov tuab ntawm txheej tom qab pleev xim, thaum kuaj cov xov nrog cov ntsuas kam rau siab sib xws, tej zaum yuav muaj qee qhov xwm txheej uas lawv tsis haum. Lub sijhawm no, kev sim teeb tsa txiv ntoo nrog cov lus qhia sib xws tuaj yeem ua tiav.
Daim Ntawv Thov
DIN 933 bolt yog lub taub hau hexagonal threaded tag nrho nrog ntau yam kev siv, feem ntau pom muaj nyob rau hauv cov teb hauv qab no:
1. Kev tsim khoom siv kho tshuab: siv rau kev sib dhos thiab kev kho cov khoom siv kho tshuab, txuas ntau yam khoom siv kho tshuab.
2. Kev tsim kho vaj tse: xws li kho cov qauv hlau, txhim kho cov brackets, connectors, thiab lwm yam.
3. Kev lag luam tsheb: siv tau rau kev txuas cov khoom xws li lub cav, chassis, thiab lub cev ntawm lub tsheb.
4. Cov khoom siv hluav taws xob: Lawv ua lub luag haujlwm hauv kev txuas thiab kho hauv kev sib dhos ntawm qee cov khoom siv hluav taws xob.
5. Kev lag luam petrochemical: tsim nyog rau kev sib txuas ntawm cov khoom siv tshuaj lom neeg, cov kav dej, thiab lwm yam. Qee qhov DIN 933 bolts tuaj yeem ua tau raws li qhov xav tau tiv thaiv xeb ntawm cov tshuaj lom neeg ib puag ncig.
6. Kev lag luam nkoj: siv rau kev tsim nkoj thiab kev teeb tsa khoom siv.
7. Kev Siv Dav Hlau: Siv rau hauv cov cheeb tsam uas muaj kev xav tau siab rau lub zog thiab kev ntseeg tau.
8. Lub zog fais fab: suav nrog kev teeb tsa thiab kho cov khoom siv xws li cua tshuab thiab lub zog hnub ci.
9. Kev tsim cov twj tso kua mis thiab cov li qub: ua cov khoom sib txuas rau cov twj tso kua mis thiab cov kav li qub.
10. Cov khoom siv hauv kev lag luam: Kev sib dhos ntawm ntau yam khoom siv hauv kev lag luam dav dav.
