10.9 qib boltsyog cov bolts muaj zog nrog hardness ntawm 10 thiab 12 qib. Lub hardness ntawm lub bolt yog hais txog lub zog tensile thiab hardness Performance index ntawm nws cov khoom. Hauv qib 10.9 bolts, tus naj npawb 10 sawv cev rau lub zog tensile yam tsawg kawg nkaus ntawm 1000 MPa (megapascals), thiab tus lej 9 sawv cev rau qhov tsawg kawg nkaus yield zog ntawm 900 MPa. Qhov no txhais tau hais tias qib 10.9 bolts muaj lub zog thiab tawv heev, ua rau lawv tsim nyog rau cov ntawv thov uas tuaj yeem tiv taus qhov hnyav thiab kev co.
10.9 qib bolts feem ntau yog ua los ntawm carbon steel (xws li 40Cr, 35CrMo, thiab lwm yam) thiab tau txais kev kho cua sov thiab quenching txheej txheem los txhim kho lawv cov hardness thiab lub zog. Lawv feem ntau siv rau hauv thaj chaw xws li cov cuab yeej siv tshuab hnyav, txuas hniav, cov qauv tsim, tsheb, thiab maus taus los muab kev sib txuas thiab kev txhawb nqa.
Nws yuav tsum raug sau tseg tias thaum txhim kho thiab siv qib 10.9 bolts, cov kev qhia tshwj xeeb ntawm kev teeb tsa thiab kev siv yuav tsum tau ua raws li txhawm rau txhawm rau txhawm rau nruj nruj thiab kev sib txuas ua haujlwm. Yog tias tsim nyog, thov nrog ib tus kws tshaj lij lossis cov ntawv qhia kev tsim nyog rau cov ncauj lus kom ntxaws ntxiv.
Thaum nws los txog qib 10.9 bolts, cov hauv qab no yog qee cov ntaub ntawv ntxiv uas tuaj yeem muab rau koj:
1. Kev cim thiab kev txheeb xyuas: Qib 10.9 bolts feem ntau muaj cov cim ntawm lawv lub taub hau, xws li 10.9, 10.9T, 10.9S, thiab lwm yam, txhawm rau pab txhawb kev txheeb xyuas thiab sib txawv ntawm lawv cov qib thiab cov yam ntxwv.
2. Lub zog thiab kev siv:Qib 10.9 boltsmuaj lub zog tensile siab thiab yield zog. Vim lawv lub zog siab thiab hardness, lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog siab lossis kev vibration thiab cuam tshuam, xws li cov cuab yeej siv tshuab hnyav, txuas hniav, tsheb cav, thiab lwm yam.
3. Tightening force thiab pre tightening force: Thaum siv qib 10.9 bolts, qhov tsim nyog zawm quab yuam yuav tsum tau txiav txim siab raws li qhov kev thov tshwj xeeb. Qhov no tuaj yeem ua kom muaj kev ntseeg siab thiab ruaj khov ntawm cov ntsia hlau txuas. Thov xa mus rau cov kev qhia tshwj xeeb ntawm kev teeb tsa thiab cov txheej txheem txhawm rau txhawm rau txhawm rau nruj nruj thiab ua ntej.
4. Txoj kev txhim kho: Thaum txhim kho qib 10.9 bolts, txoj kev txhim kho kom raug thiab cov kauj ruam yuav tsum ua raws. Qhov no suav nrog kev siv lub zog tsim nyog lossis lub zog tensile, kev siv cov bolts thiab cov txiv ntoo kom raug, thiab siv cov roj nplua nyeem tsim nyog. Txoj kev txhim kho kom raug pab txhawm rau txhawm rau ua kom nruj thiab ua haujlwm ntawm bolts.
5. Kev tswj kom zoo: txhawm rau ua kom zoo thiab ua tau zoo ntawm qib 10.9bolts, nws raug nquahu kom xaiv cov neeg muab khoom thiab cov chaw tsim khoom txhim khu kev qha, thiab xyuas kom meej tias lawv cov khoom ua raws li cov qauv zoo thiab cov ntawv pov thawj uas yuav tsum tau ua. Qhov no tuaj yeem muab kev daws teeb meem txuas ntxiv txhim khu kev qha thiab ruaj ntseg.
Thov nco ntsoov tias cov kev thov tshwj xeeb thiab kev siv yuav txawv nyob ntawm qhov sib txawv ntawm kev lag luam, khoom siv, thiab cheeb tsam. Yog li ntawd, thaum xaiv thiab siv qib 10.9 bolts, nws yog qhov zoo tshaj rau xa mus rau cov qauv, cov lus qhia, thiab cov lus pom zoo los xyuas kom muaj kev sib raug zoo thiab txhim khu kev qha.
