Qhov tseeb, hexagon bolts muaj peb qib: A, B thiab C, nrog rau qhov sib txawv hauv qab no.
Hexagon bolts tau muab faib ua peb qib: qib A, qib B thiab qib C. Bolt kev twb kev txuas tuaj yeem muab faib ua cov ntsia liaj qhov rooj zoo tib yam thiab kev sib txuas ntawm cov ntsia hlau muaj zog.Ordinary bolts tuaj yeem muab faib ua qib A, B thiab C. Ntawm no, Qib A, B thiab C xa mus rau qib siab siab ntawm bolts, Qib A yog qib precision, Qib B yog qib zoo tib yam, thiab Qib C yog qib xoob.Koj puas paub qhov txawv ntawm peb qib?
Qib A thiab B yog cov ntsia hlau ua kom zoo, thiab qib C yog cov ntsia hlau ntxhib.Class A thiab B refined bolts muaj du nto, qhov loj me, siab yuav tsum tau rau lub qhov zoo, complex fabrication thiab installation, thiab tus nqi siab, uas tsis tshua muaj siv nyob rau hauv steel qauv.Qhov sib txawv ntawm qib A thiab B refined bolts tsuas yog qhov ntev ntawm tus ntsia liaj qhov rooj.Qib C bolts feem ntau tuaj yeem siv rau kev sib txuas ntawm qhov nro ntawm cov ntsia liaj qhov rooj axis, nrog rau kev sib txuas ntawm cov txheej txheem thib ob lossis kev kho ib ntus thaum lub sijhawm teeb tsa.
Chav Kawm A yog siv rau hauv qhov chaw tseem ceeb nrog kev sib dhos siab thiab qhov chaw muaj kev cuam tshuam loj, kev co lossis kev thauj khoom sib txawv.Class A yog siv rau bolts nrog d = 1.6-24mm thiab l ≤ 10d lossis l ≤ 150mm.Qib B yog siv rau bolts nrog d> 24mm lossis l> 10d lossis l ≥ 150mm.Qib B ntawm cov pas nrig nyias yog M3-M20 hexagonal flange bolt nrog kev ua haujlwm zoo los tiv thaiv xoob.Chav kawm C yog nyob nruab nrab ntawm M5-M64.Qib C hexagon bolts feem ntau yog siv hauv cov tshuab siv steel thiab cov khoom siv nrog cov tsos ntxhib thiab tsis tshua muaj qhov yuav tsum tau ua kom raug.Feem ntau, Qib C raug xaiv rau kev sib txuas.
Qib A thiab B hexagon bolts feem ntau yog siv rau hauv cov tshuab thiab cov cuab yeej siv nrog cov tsos du thiab siab precision.Cov qauv kev tswj hwm muaj raws li hauv qab no: Torsional shear type high-strength bolt txuas khub rau steel qauv GB / T3632-1995;Lub zog loj hexagon taub hau bolts rau steel qauv GB / T1228 - 1991;Lub zog muaj zog loj Hexagon ceev rau cov qauv hlau (GB/T1229-1991);Lub zog siab siab rau cov qauv hlau GB / T1230 - 1991;Cov xwm txheej kev ua haujlwm rau lub zog siab loj Hexagon taub hau Bolts, Loj Hexagon Ceev thiab Washers rau Steel Structures (GB / T1231-1991).Cov khoom lag luam kev ua tau zoo thiab cov qauv kev tswj hwm Cov khoom lag luam yog tsim raws li DIN, ISO, ANSI, JIS, AS, NF, GB / T thiab lwm yam qauv.Lub zog qib tuaj yeem ncav cuag 4.4 ~ 12.9, thiab cov qauv hlau tuaj yeem ncav cuag 8.8S thiab 10.9SHauv ib lo lus, qhov tseeb ntawm bolts txawv, thiab lub zog tawm los kuj txawv.Peb cov qauv siv tshuab yog qhov yooj yim txaus los xaiv Qib C thiab Qib B, thiab tus nqi ntawm Qib A yuav nce mus.Tsis txhob underestimate cov bolts.Tus nqi ntawm cov khoom seem nyob rau theem tom qab yog qhov tseem ceeb heev.
