Khoom piav qhia thiab siv

Cia peb nkag siab ua ntej yog dab tsi yog lub steel qauv high-strength bolt.Nws feem ntau yog ua los ntawm cov cua kub-kho siab-lub zog steel (35CrMo\35 cov khoom siv carbon steel, thiab lwm yam), uas tuaj yeem muab faib ua 8.8 qib raws li qib kev ua tau zoo.Qib 10.9, tsis zoo li qub bolts, bolts yuav tsum siab dua qib 8.8.Tsis tas yuav tsum tau muab tso rau hauv cov kev cai ntawm qib steel thiab qib steel thaum xaiv.Kev sib txhuam pob qij txha yog siv dav hauv steel qauv engineering.

Steel qauv high-strength bolts yuav muab faib ua ob hom: kev sib txhuam hom kev twb kev txuas thiab siab hom kev twb kev txuas raws li lub zog yam ntxwv.Kev sib txuas nto ntawm lub siab-lub zog bolt-cov kabmob hom kev sib txuas tsuas yog yuav tsum tau xeb-pov thawj.Txawm li cas los xij, kev sib txhuam hom muaj zog bolts muaj qhov zoo ntawm kev sib txuas ceev, lub zog zoo, qaug zog, thiab tsim nyog rau kev coj tus kheej dynamic loads, tab sis qhov kev sib txuas saum npoo yuav tsum tau kho nrog kev sib txhuam nto, feem ntau yog sandblasting, sandblasting, thiab ces coated nrog. inorganic zinc-nplua nuj xim.

Vim tias qhov sib txawv ntawm cov qauv ntsia hlau thiab kev tsim kho, lub zog siab bolts rau cov qauv hlau tuaj yeem muab faib ua ob hom: loj hexagonal taub hau siab zog bolts thiab torsional shear hom high-strength bolts.Hom hex loj loj yog tib yam li cov hex taub hau bolts zoo tib yam.Lub taub hau ntawm lub taub hau torsion txiab zoo ib yam li lub taub hau rivet, tab sis cov xov kawg ntawm lub torsion txiab muaj lub torx collet thiab annular groove los tswj lub nruj torque.Qhov txawv no yuav tsum tau saib xyuas.

Lub bolt txuas khub muaj peb ntu: ntsia liaj qhov rooj, txiv ntseej thiab ntxhua khaub ncaws.Cov qauv thiab cov kev xav tau ntawm cov bolts muaj zog yog tib yam li cov bolts zoo tib yam.Tom qab ntawd nws yuav tsum tau siv raws li qhov tshwj xeeb.Tsuas yog cov bolts muaj zog ntawm qib 8.8 tuaj yeem siv rau lub taub hau hexagon loj, thiab lub zog siab bolts ntawm qib 10.9 tsuas yog siv rau torsion shear type high-strength bolts.

Lub preloading ntawm high-strength bolts nyob rau hauv steel qauv yog tiav los ntawm nruj ceev.Lub preload feem ntau yog tswj los ntawm twisting tawm lub ntsia liaj qhov rooj tail siv torque txoj kev, lub kaum sab xis txoj kev los yog Torx txoj kev.

Tam sim no muaj ib tug tshwj xeeb wrench uas qhia torque.Siv cov kev sib raug zoo ntawm qhov ntsuas torque thiab cov ntsia liaj qhov rooj nro, torque yog siv los ua kom tiav qhov tsim nyog tshaj tus nqi.

Cov txheej txheem kaum sab xis yog muab faib ua ob kauj ruam, ib qho yog qhov pib screwing, thiab lwm qhov yog qhov kawg screwing.Txhawm rau muab nws yooj yim, qhov kev sib khi thawj zaug feem ntau ua los ntawm tus neeg ua haujlwm siv ib qho kev sib txuas los ua kom cov khoom sib txuas zoo sib xws, thiab qhov kawg nruj pib los ntawm qhov pib zawm txoj hauj lwm, thiab lub kaum sab xis kawg yog raws li txoj kab uas hla ntawm lub ntsia liaj qhov rooj. thiab lub thickness ntawm lub phaj pawg.Siv ib tug muaj zog ciaj ntswj tig lub txiv ntseej thiab ntsia hlau nws mus rau lub predetermined lub kaum sab xis tus nqi, thiab qhov nro ntawm lub ntsia liaj qhov rooj tuaj yeem ncav cuag tus nqi preload.Txhawm rau tiv thaiv lub torque coefficient ntawm high-strength bolts los ntawm kev hloov pauv vim muaj kev cuam tshuam ntawm ib puag ncig sab nraud, qhov pib thiab qhov kawg nruj yuav tsum tau ua kom tiav nyob rau tib hnub.

Cov yam ntxwv kev ntxhov siab ntawm torsional shear high-strength bolts yog tib yam li cov khoom siv dav dav dav dav, tshwj tsis yog tias txoj kev siv pretension yog los tswj tus nqi pretension los ntawm twisting seem ntawm qhov txiav.Twist ntawm lub bolt.

Kev sib txhuam hom kev sib txuas ntawm lub zog siab kawg nkaus tso siab rau kev sib txhuam ntawm cov khoom sib txuas kom xa cov quab yuam, thiab kev sib txhuam tsis yog tsuas yog lub zog ua ntej nruj ntawm lub ntsia liaj qhov rooj, tab sis kuj muaj cov cuab yeej tiv thaiv kev sib txhuam ntawm qhov sib txhuam. txiav txim los ntawm kev kho deg.Cov khoom ntawm cov khoom sib txuas thiab nws qhov chaw sib cuag.coefficient.

Tom qab nyeem nws, Kuv ntseeg tias txhua tus neeg tau nkag siab qhov tseeb, qhov twg cov bolts muaj zog yuav tsum tau siv, thiab ua haujlwm kom raug thiab nruj.
