Taw qhia
Rivets thiab bolts yog ob qho tib si kho vajtse siv hauv engineering thiab kev tsim kho cov haujlwm. Txawm li cas los xij, muaj qhov sib txawv ntawm lawv cov kev siv thiab cov yam ntxwv uas ua rau lawv zoo dua rau qee yam kev siv. Hauv kab lus no, peb yuav tshawb txog qhov sib txawv ntawm rivets thiab bolts thiab thaum twg yuav tsum tau siv.
rivets yog dab tsi?
Lub rivet yog ib hom fastener uas feem ntau siv hauv kev tsim kho thiab kev tsim khoom. Nws feem ntau yog ua los ntawm ib lub cylindrical ncej nrog lub taub hau ntawm ib kawg thiab tus Tsov tus tw ntawm lwm tus. Cov ncej yog ntxig los ntawm ib lub qhov ntawm cov khoom uas tau koom nrog, thiab tus Tsov tus tw yog deformed kom ruaj ntseg rivet nyob rau hauv qhov chaw.
Muaj ntau ntau hom rivets, nrog rau cov khoom, semi-tubular, thiab qhov muag tsis pom. Cov khoom rivets yog hom yooj yim tshaj plaws thiab siv thaum sib koom ua ke yog npaj kom ruaj khov. Semi-tubular rivets muaj ib lub qhov nyob rau hauv lub ncej thiab yog siv thaum lub sib koom yuav tsum tau muab tshem tawm ib feem. Qhov muag tsis pom rivets, tseem hu ua pop rivets, yog siv thaum ib sab ntawm qhov sib koom ua ke tsis siv tau. Lawv tau teeb tsa siv lub cuab yeej tshwj xeeb uas rub lub mandrel los ntawm rivet, ua rau nws nthuav dav thiab ruaj ntseg ntawm kev sib koom tes.
bolts yog dab tsi?
Bolts yog threaded fasteners uas feem ntau siv hauv kev tsim kho thiab kev tsim khoom. Lawv muaj ib tug ncej nrog lub taub hau ntawm ib kawg thiab ib tug threaded feem rau lwm yam. Ib tug txiv ntseej feem ntau yog threaded rau lub bolt kom ruaj ntseg sib koom ua ke.
Muaj ntau hom bolts, nrog rau hex bolts, carriage bolts, thiab lag bolts. Hex bolts muaj lub taub hau hexagonal thiab yog siv nrog ib tug ciaj ntswj lossis lub qhov (socket). Carriage bolts muaj lub taub hau puag ncig thiab lub caj dab square uas tiv thaiv kev sib hloov thaum lub sijhawm teeb tsa. Lag bolts, tseem hu ua lag screws, yog threaded screws uas yog siv los tuav cov khoom hnyav rau ntoo.
Thaum twg siv lub rivet
Muaj ntau lub sijhawm uas lub rivet yuav yog qhov kev xaiv zoo dua li lub bolt.
- Thaum ib qho kev sib koom ua ke yuav tsum tau mus tas li.Rivets yog tsim los ua kom ruaj khov, ua rau lawv zoo tagnrho rau cov xwm txheej uas qhov sib koom ua ke yog npaj kom nyob twj ywm hauv qhov chaw rau lub neej ntawm cov khoom. Bolts, ntawm qhov tod tes, tuaj yeem raug tshem tawm thiab hloov tau yooj yim, ua rau lawv tsis haum rau cov pob qij txha mus tas li.
- Thaum koom nrog cov ntaub ntawv uas nyuaj rau kev xyaum.Rivets feem ntau tuaj yeem ntsia tau rau hauv cov ntaub ntawv uas nyuaj rau kev xyaum, xws li cov ntawv hlau lossis cov yas nyias. Vim tias cov rivet nthuav dav raws li nws tau teeb tsa, nws tuaj yeem tsim kom muaj kev ruaj ntseg sib koom ua ke yam tsis tas yuav tsum muaj lub qhov threaded.
- Thaum koom nrog cov ntaub ntawv uas nyias dhau rau lub bolt.Bolts xav tau qhov tsawg kawg nkaus xov txuas ntev los xyuas kom muaj zog txaus. Yog tias cov ntaub ntawv sib koom ua ke yog nyias dhau los tso cai rau kev sib koom ua ke ntawm cov xov, rivet yuav yog qhov kev xaiv zoo dua.
- Thaum qhov chaw txwv.Rivets siv qhov chaw tsawg dua li bolts thiab txiv ntseej, ua rau lawv xaiv zoo dua nyob rau hauv qhov chaw nruj lossis thaum hnyav yog qhov kev txhawj xeeb.
Thaum twg siv lub bolt
Muaj ntau qhov xwm txheej uas lub bolt yuav yog qhov kev xaiv zoo dua li rivet.
- Thaum lub sib koom yuav tsum tau adjustable los yog tshem tau.Bolts tuaj yeem raug tshem tawm thiab hloov tau yooj yim, ua rau lawv zoo tagnrho rau cov xwm txheej uas qhov sib koom ua ke yuav tsum tau hloov kho lossis disassembled yav tom ntej.
- Thaum qhov sib koom ua ke yuav raug shear lossis nro loads.Bolts yog tsim los tswj cov shear thiab nro loads, ua rau lawv zoo tagnrho rau cov pob qij txha uas lub zog yog qhov tseem ceeb. Rivets, ntawm qhov tod tes, yog qhov zoo dua rau cov xwm txheej uas qhov sib koom ua ke yuav raug rau cov khoom thauj.
- Thaum cov ntaub ntawv tau koom nrog yog tuab heev rau lub rivet.Rivets xav tau qee qhov ntev ntawm tus Tsov tus tw los tsim kom muaj kev ruaj ntseg sib koom ua ke. Yog tias cov ntaub ntawv sib koom ua ke yog tuab heev kom tso cai rau qhov ntev ntawm tus Tsov tus tw, lub bolt yuav yog qhov kev xaiv zoo dua.
- Thaum ib tug threaded sib koom yuav tsum tau.Bolts yog threaded, ua rau lawv zoo tagnrho rau cov xwm txheej uas yuav tsum tau muaj kev sib koom tes threaded. Rivets, ntawm qhov tod tes, tsim kom muaj kev sib koom ua ke, tsis muaj xov.
Xaus
Hauv kev xaus, ob qho tib si rivets thiab bolts muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, ua rau lawv zoo dua rau qee yam kev siv. Thaum txiav txim siab seb puas yuav siv lub rivet lossis lub bolt, xav txog yam xws li kev ua haujlwm ruaj khov ntawm kev sib koom ua ke, cov ntaub ntawv tau koom nrog, thiab cov khoom sib koom ua ke yuav raug rau. Los ntawm kev xaiv txoj cai fastener rau txoj haujlwm, koj tuaj yeem ua kom muaj kev ruaj ntseg, kev sib koom ua haujlwm ntev uas yuav ua tau raws li qhov xav tau ntawm koj qhov project.
