Bolts yog ib qho tseem ceeb hauv kev tsim khoom thiab engineering industries. Los ntawm cov tshuab tsis sib xws ntawm cov tsheb mus rau cov qauv tsim ntawm cov choj thiab cov tsev, cov bolts ua lub luag haujlwm tseem ceeb hauv kev ua kom txhua yam ua ke. Vim li no, nws yog ib qho tseem ceeb kom nkag siab tias cov bolts tiag tiag yog dab tsi, ntxiv rau txhua hom, qib, nomenclature, thiab functionalities txuam nrog lawv.
Peb npog tag nrho cov ntaub ntawv hauv qab no. Xav tias dawb siv cov lus hauv qab no kom dhia mus rau ib ntu tshwj xeeb uas koj nyiam.

Kev txhais ntawm Bolt
Ib tug ntsia liaj qhov rooj yog ib tug externally threaded fastener tsim rau kev ntxig los ntawm qhov hauv cov khoom sib dhos.Feem ntau, nws yog npaj kom nruj los yog tso tawm los ntawm torquing ib tug txiv ntseej.
Thaum muaj ntau hom bolts thiab lawv cov qauv sib txawv, feem ntau cov bolts muaj cov yam ntxwv dav dav. Lawv muaj ib tug threaded cylindrical pas nrig, nrog rau lub taub hau ntawm ib kawg thiab, feem ntau, ib tug txiv ntseej ntawm lwm yam. Bolt taub hau yog ib txwm loj dua lawv lub cev, uas yog ib qho kev tsim uas pab faib cov khoom thauj ntawm cov khoom raug fastened hla ib cheeb tsam loj. Cov txiv ntoo cuam tshuam yog siv los tiv thaiv cov khoom sib koom hauv qhov chaw.
Bolts yog siv rau ntau daim ntawv thov, nrog rau kev tsim kho, kev tsim khoom, thiab kev lag luam automotive yog qhov feem ntau.
Qhov txawv ntawm ib lub Bolt thiab ib tug ntsia hlau
Bolts muaj feem xyuam nrog screws. Yog li, koj tuaj yeem qhia qhov txawv li cas?
Zoo, nws nyob ntawm koj nug. Cov kws tshaj lij kev lag luam muaj ntau yam kev xav txog qhov sib txawv ntawm cov khoom no. Txawm hais tias peb tsis tuaj yeem muab cov lus teb meej meej rau koj, peb tuaj yeem muab ib qho kev xav los ntawm lub chaw haujlwm uas peb ntseeg siab. Raws li US Customs and Border Protection Agency (CBP), cov no yog cov ntsiab lus rau bolts thiab screws:
Lub ntsia liaj qhov rooj yog ib qho kev sib txuas sab nraud uas tsim los rau kev ntxig los ntawm lub qhov hauv cov khoom sib dhos thiab feem ntau yog npaj kom nruj los yog tso tawm los ntawm torquing lub txiv ntoo.
Lub ntsia hlau yog ib qho kev sib txuas sab nraud uas muaj peev xwm muab tso rau hauv qhov hauv cov khoom sib dhos, mating nrog cov xov hauv preformed los yog tsim nws tus kheej xov, thiab raug nruj los yog tso tawm los ntawm torquing lub taub hau.
Ntxiv dua thiab, cov no yog cov ntsiab lus los ntawm tsuas yog ib qho ntawm ntau qhov chaw ntseeg tau. Ntxiv rau, koj tuaj yeem pom tias qhov sib txawv me ntsis. CBP tseem sau 13 lwm yam tseem ceeb thiab cov txheej txheem ntxiv, uas koj tuaj yeem tshawb hauv qhov blog no.
Bolt Ua li cas?
Muaj peb txoj hauv kev los tsim cov bolts: txias sib sau, kub forging, thiab machining.
Txias txoj kevyog cov txheej txheem ntawm kev tsim lub bolt yam tsis muaj cua sov li cov khoom siv. Nws tau ua tiav los ntawm kev tawm tsam lossis nias cov khoom hauv qhov tuag los tsim qhov ntev uas xav tau.
Kub forgingyog cov txheej txheem ntawm cua sov cov khoom mus rau qhov chaw uas nws ua malleable, ces ua rau nws tuag.
Tshuab dhosyog cov txheej txheem ntawm kev siv tshuab txiav tawm cov khoom kom txog rau thaum nws haum raws li qhov xav tau.
Txhua yam ntawm cov txheej txheem tsim cov ntsia liaj qhov rooj muaj nws tus kheej qhov zoo thiab qhov tsis zoo, uas koj tuaj yeem nyeem txog hauv kab lus no. Peb siv cov txheej txheem txias feem ntau ntawm Wilson-Garner, raws li peb ntseeg tias nws yuav ua rau cov khoom muaj zog thiab zoo tshaj plaws. Txawm li cas los xij, peb kuj siv machining thaum nws ua rau kev txiav txim siab ua li ntawd.
Yog tias koj xav tau sab hauv saib yuav ua li cas peb tsim bolts ntawm Wilson-Garner, mus saib pebbolt manufacturing qhia nrog cov duab.
Hom Hom Bolts
Muaj ntau hom bolts, tag nrho nrog cov yam ntxwv sib txawv thiab siv rooj plaub. Hauv qab no yog ib daim ntawv teev cov feem ntau hom.
Muab boltsfeature self-locking, free-spinning hex taub hau uas tiv thaiv loosening vim kev co. Nyeem ntxiv txog lawv ntawm no.
Carriage boltsfeature txo lub cev diameters thiab loj, domed hau.
Hex boltsfeature six-sided hex caps ntawm ib kawg. Nyeem ntxiv txog lawv ntawm no.
Flange boltsfeature washers nyob rau hauv qab ntawm lawv lub taub hau, uas pab faib lub zog ntawm bearing loads ntau npaum.
Lub xub pwg boltsfeature ib tug du, cylindrical xub pwg ntawm lawv lub taub hau thiab threaded seem. Lub xub pwg yog feem ntau loj nyob rau hauv txoj kab uas hla tshaj qhov threaded feem, ua raws li ib tug kev taw qhia rau kev sib hloov ntawm ib tug mating ib feem.
Tshuab boltsfeature ib lub taub hau square ntawm ib kawg thiab ib qho semi-cone point ntawm lwm yam.
Kev cai bolts, tseem hu ua bolts tshwj xeeb, tshwj xeeb tsim thiab tsim rau kev siv tshwj xeeb. Mus saib peb cov kev cai bolt manufacturing peev xwm ntawm no.
Nkag siab Bolt Qib
Bolt qib yog txhais los ntawm lawv cov khoom tshwj xeeb, ntxiv rau lub zog ntawm cov khoom ntawd. Lawv txheeb xyuas qhov kev ntxhov siab uas ib lub bolt tuaj yeem tiv taus. Feem ntau, qhov siab dua tus lej lossis qib ntawv, qhov kev ntxhov siab ntau dua tuaj yeem daws tau.
Muaj ntau lub koom haum tswj hwm uas tsim cov qauv rau bolt grading systems. SAE, ISO (metric), thiab ASTM yog peb qhov piv txwv peb feem ntau siv.
SAEsawv cev rau Society of Automotive Engineers. SAE qib yog qee qhov feem ntau siv rau qhov ntiv tes. Ib qho tseem ceeb SAE tus qauv yog SAE J429, uas muaj bolt qib 2, 5, thiab 8.
ISOsawv cev rau International Standards Organization. ISO cov qauv kuj tseem hu ua metric qauv, thiab lawv "qib" yog hu ua cov chav kawm khoom vaj khoom tsev. Cov chav kawm ISO feem ntau rau cov bolts yog ISO 898-1 Cov Chav Kawm 8.8, 10.9, thiab 12.9.
ASTMsawv cev rau American Society for Testing and Materials. ASTM muaj ntau tus qauv nrov rau bolts (ntxiv rau lwm cov fasteners), xws li ASTM A307, ASTM A193, thiab ASTM A354.
Kev nkag siab txog cov qhab nias yog qhov tseem ceeb thaum koj txiav txim siab qhov twg koj xav tau rau ib daim ntawv thov tshwj xeeb. Piv txwv li, koj tsis xav siv SAE J429 Qib 2 bolt sib hloov nrog ISO 898-1 Cov Khoom Siv Chav 12.9 ntsia liaj qhov rooj, vim lawv muaj peev xwm sib txawv heev.
Nyeem ntxiv txog cov qhab nia sib txawv thiab lawv cov ntawv thov ntawm no.
Bolt Nomenclature rau Inch thiab Metric Parts
Txawm tias cov kws tshaj lij kev lag luam muaj caij nyoog tuaj yeem xav tau kev pab nrog cov ntsiab lus fastener. Yog tias koj tau khiav hla ib yam dab tsi zoo li5/8-11" X 4-1/2"los yogM8 X 1.25 X 65MM, tej zaum koj yuav tsis paub tias qhov ntawd txhais li cas lossis yuav ua li cas nrog cov ntaub ntawv. Peb mam li tawg rau koj hauv qab no.
