Cov yam ntxwv tsis zoo thiab kev ua haujlwm ntawm bolts.

Tus qauv parameter

Raws li lub zog hom kev sib txuas, nws tau muab faib ua qhov zoo tib yam thiab hinged qhov. Raws li cov duab ntawm lub taub hau: hexagonal taub hau, puag ncig lub taub hau, square taub hau, countersunk taub hau thiab hais txog. Lub taub hau hexagonal yog feem ntau siv. Feem ntau, lub taub hau countersunk yog siv qhov twg qhov kev sib txuas yog xav tau.

Lub npe lus Askiv ntawm tus ntsia liaj qhov rooj yog U-bolt, qhov tsis yog qauv, cov duab yog U-puab yog li nws tseem hu ua U-bolt, thiab cov xov ntawm ob qho kawg tuaj yeem ua ke nrog cov txiv ntoo, feem ntau yog siv los kho. cov yeeb nkab xws li cov yeeb nkab dej los yog cov flake xws li lub phaj caij nplooj ntoos hlav ntawm lub tsheb, vim txoj kev kho cov khoom zoo li tus neeg caij nees, nws yog hu ua bolt caij. Raws li qhov ntev ntawm cov xov yog muab faib ua cov xov tag nrho thiab cov xov tsis puv ob pawg.

Nws tau muab faib ua cov hniav ntxhib thiab cov hniav zoo raws li cov hniav ntawm cov xov, thiab cov hniav ntxhib hom tsis pom nyob rau hauv cov cim ntawm lub bolt. Bolts tau muab faib ua 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9, 12.9 yim qib raws li qib kev ua tau zoo, ntawm 8.8 (xws li 8.8) bolts yog ua los ntawm cov hlau tsis tshua muaj carbon hlau lossis nruab nrab carbon steel thiab kho cua sov ( quenching + tempering), feem ntau hu ua bolts siab zog, 8.8 (tsis suav 8.8) feem ntau hu ua bolts zoo tib yam.

Ordinary bolts raws li qhov raug ntau lawm tuaj yeem muab faib ua A, B, C peb qib, A, B rau kev ua kom zoo bolts, C rau ntxhib bolts. Rau kev sib txuas bolts rau cov qauv steel, tshwj tsis yog tias tau teev tseg, lawv feem ntau yog C-class bolts. Muaj qhov sib txawv ntawm cov txheej txheem ntawm ntau theem, feem ntau yog ua raws li cov txheej txheem ua raws li hauv qab no: ① bolt pas nrig ntawm A thiab B bolts yog ua tiav los ntawm tshuab dhos, qhov saum npoo yog du, qhov loj me yog qhov tseeb, cov khoom siv tau zoo yog qib 8.8. , ntau lawm thiab installation yog complex, tus nqi yog siab, thiab nws yog tsis tshua muaj siv; Chav Kawm C bolts yog ua los ntawm cov hlau tsis muaj txheej txheem, qhov loj me tsis raug txaus, thiab cov khoom siv qib siab yog 4.6 lossis 4.8. Lub shear kev twb kev txuas deformation yog loj, tab sis lub installation yog yooj yim, cov nqi ntau lawm yog tsawg, thiab nws yog feem ntau siv rau ib ntus kho thaum lub sij hawm tensile kev twb kev txuas los yog installation.

Kev siv ua haujlwm

Muaj ntau lub npe rau bolts, thiab txhua tus neeg lub npe yuav txawv, qee tus neeg hu ua screws, qee cov neeg hu ua bolts, thiab qee cov neeg hu ua fasteners. Txawm hais tias muaj ntau lub npe, tab sis lub ntsiab lus yog tib yam, yog bolts. Bolt yog ib lo lus dav dav rau fasteners. Cov ntsia liaj qhov rooj yog ib qho cuab yeej ua kom nruj qhov chaw ntawm kauj ruam siv lub cev nqaij daim tawv thiab kev ua lej ntawm cov dav hlau ncig tig thiab kev sib txhuam ntawm cov khoom.

Bolts yog qhov tseem ceeb hauv lub neej niaj hnub thiab kev tsim khoom thiab kev tsim khoom, thiab bolts tseem hu ua industrial meters. Nws tuaj yeem pom tias kev siv bolts yog dav. Daim ntawv thov ntau yam ntawm bolts yog: cov khoom siv hluav taws xob, cov khoom siv tshuab, cov khoom siv digital, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Bolts kuj tseem siv rau hauv nkoj, tsheb, cov haujlwm hydraulic, thiab txawm tias kev sim tshuaj. Bolts yog siv nyob rau hauv ntau qhov chaw lawm. Xws li cov precision bolts siv hauv cov khoom lag luam digital. Miniature bolts rau DVDS, koob yees duab, tsom iav, moos, electronics, thiab lwm yam. General bolts rau TV, khoom siv hluav taws xob, Suab paj nruag, rooj tog, thiab lwm yam.; Rau tej yaam num, vaj tse thiab choj, bolts loj thiab ceev yog siv; Cov khoom siv thauj mus los, dav hlau, tsheb ciav hlau, tsheb, thiab lwm yam, yog siv cov bolts loj thiab me. Bolts muaj cov haujlwm tseem ceeb hauv kev lag luam, thiab tsuav yog muaj kev lag luam hauv ntiaj teb, kev ua haujlwm ntawm bolts yuav yog ib qho tseem ceeb.
