1. Kev faib cov fasteners
Muaj ntau ntau hom fasteners, uas tuaj yeem muab faib ua cov pawg hauv qab no raws li cov duab thiab kev ua haujlwm:
Bolt: Lub cylindrical fastener nrog threads, feem ntau yog siv nrog cov txiv ntseej, kom ua tiav cov nyhuv nruj los ntawm kev tig cov txiv ntoo. Bolts tau siv dav hauv ntau yam khoom siv tshuab thiab cov qauv, thiab yog cov khoom tseem ceeb rau kev sib txuas thiab kho qhov chaw.
Txiv ntseej: Cov txiv ntoo yog ib qho khoom siv ua ke nrog cov ntsia liaj qhov rooj, uas muaj cov qhov hauv qhov uas phim cov ntsia liaj qhov rooj. Los ntawm kev tig lub txiv ntoo, nws muaj peev xwm zawm los yog loosen lub ntsia liaj qhov rooj.
Ntsia Hlau: Ib qho ntsia hlau yog ib hom fastener nrog cov xov sab nraud, feem ntau screwed ncaj qha mus rau hauv lub threaded qhov ntawm qhov txuas yam tsis tas yuav tsum muaj cov txiv ntoo kom haum. Screws tuaj yeem ua haujlwm rau ob qho tib si fastening thiab positioning lub hom phiaj thaum lub sij hawm kev sib txuas.
Stud: Ib tug stud yog ib hom fastener nrog threads ntawm ob hnub, feem ntau yog siv los txuas ob lub thicker Cheebtsam. Cov nyhuv fastening ntawm bolts yog ruaj khov thiab haum rau cov xwm txheej uas lawv tuaj yeem tiv taus siab tensile rog.
Gasket: Lub gasket yog ib qho khoom siv los ua kom thaj chaw sib txuas ntawm cov khoom sib txuas, tiv thaiv kev xoob, thiab txo qhov hnav. Gaskets feem ntau yog siv ua ke nrog fasteners xws li bolts thiab ceev.
Tus kheej tapping ntsia hlau: Tus kheej tapping ntsia hlau yog ib hom ntsia hlau nrog cov xov tshwj xeeb uas tuaj yeem ncaj qha kais threaded qhov rau hauv qhov txuas thiab ua tiav fastening. Self tapping screws yog dav siv rau kev sib txuas cov ntaub ntawv nyias.
Rivet: Ib lub rivet yog ib qho fastener uas txuas ob lossis ntau yam khoom ua ke los ntawm riveting. Cov riveted connectors muaj siab zog thiab stability.
Kev muag khoom: Kev muag khoom yog fasteners siv los txuas thiab tso ob yam khoom. Kev muag khoom feem ntau muaj cov kab me me thiab qhov ntev ntev, ua rau lawv haum rau cov xwm txheej uas xav tau qhov tseeb.
Lub nplhaib tuav: Lub nplhaib tuav yog ib qho khoom siv los tiv thaiv axial txav ntawm lub ncej lossis nws cov khoom. Lub nplhaib tuav feem ntau yog ntsia rau ntawm lub ntsej muag kawg ntawm lub ntsej muag lossis lub qhov, txwv txoj kev txav axial ntawm lub ncej lossis nws cov khoom los ntawm nws cov elasticity lossis rigidity.
Ntoo screws: Ntoo screws yog fasteners tshwj xeeb siv los txuas ntoo. Cov xov ntawm ntoo screws yog qhov ntiav, yooj yim rau ntsia hlau rau hauv ntoo, thiab muaj cov nyhuv fastening zoo.
Vuam ntsia hlau: Vuam ntsia hlau yog lub zog siab, ceev vuam fastener haum rau ntau yam steel qauv tsim thiab kev lag luam kev lag luam. Nws muaj ib tug pas nrig liab qab thiab ntsia hlau taub hau (los yog ib tug qauv uas tsis muaj tus ntsia thawv lub taub hau), uas yog fixedly txuas rau ib feem los yog ib feem los ntawm welding technology rau ruaj khov kev twb kev txuas thiab sib dhos nrog lwm yam nyob rau hauv lub neej yav tom ntej.
Kev sib dhos: Ib feem tsim los ntawm kev sib txuas ntau yam ua ke. Cov khoom no tuaj yeem yog cov khoom siv los yog cov khoom tsim tshwj xeeb. Lub hom phiaj ntawm kev sib dhos yog los pab txhawb kev txhim kho, kev saib xyuas, lossis txhim kho kev tsim khoom. Piv txwv li, muab cov bolts, txiv ntseej, thiab cov ntxhua khaub ncaws ua ke los ua ib lub rooj sib dhos uas tuaj yeem ntsia tau sai.
2. Cov ntsiab cai rau kev txiav txim siab cov qauv thiab ntau yam
Thaum xaiv cov fasteners, peb yuav tsum ua raws li cov hauv qab no los txiav txim lawv cov qauv thiab ntau yam:
Txo ntau yam thiab txhim kho kev ua tau zoo: Thaum ua tau raws li cov kev cai siv, cov txheej txheem fasteners yuav tsum raug xaiv kom ntau li ntau tau kom txo tau ntau yam thiab specifications thiab txhim kho kev tsim khoom.
Ua ntej siv cov txheej txheem khoom ntau yam: Cov khoom lag luam txheem ntau yam muaj kev sib tw siab thiab sib hloov, uas tuaj yeem txo cov nqi tsim khoom thiab kev saib xyuas. Yog li ntawd, thaum twg ua tau, qhov tseem ceeb yuav tsum tau muab rau kev siv cov qauv ntawm cov khoom.
Txiav txim siab ntau yam raws li kev xav tau: Thaum xaiv cov fasteners, tag nrho cov kev xav yuav tsum tau muab rau lawv qhov chaw siv, kev ntxhov siab, cov ntaub ntawv, thiab lwm yam los xyuas kom meej tias cov fasteners xaiv tuaj yeem ua tau raws li cov kev xav tau ntawm kev siv.
3. Mechanical Performance Level
Cov txheej txheem kev ua tau zoo ntawm cov fasteners yog qhov tseem ceeb rau kev ntsuas lawv lub zog thiab kav ntev. Raws li GB / T 3098.1-2010, bolts, screws thiab lwm yam fasteners tuaj yeem muab faib ua ntau theem xws li 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, thiab lwm yam. Cov qib no sawv cev rau lub zog tensile ntau zog. Piv txwv li, lub ntsia liaj qhov rooj nrog qib kev ua tau zoo ntawm 8.8 sawv cev rau lub zog tensile ntawm 800 MPa thiab lub zog tawm ntawm 80%, uas yog lub zog tensile ntawm 640 MPa.
4. Qib raug
Qib precision ntawm fasteners qhia txog lawv qhov raug thiab haum qhov tseeb. Raws li cov txheej txheem kev cai, cov khoom fastener tuaj yeem muab faib ua peb theem: A, B, thiab C. Ntawm lawv, qib A muaj qhov raug siab tshaj plaws thiab qib C muaj qhov raug qis tshaj. Thaum xaiv cov fasteners, lawv cov qib raug yuav tsum tau txiav txim siab raws li qhov yuav tsum tau siv.
5. Xov
Cov xov yog ib qho tseem ceeb ntawm cov fasteners, thiab lawv cov duab thiab qhov loj me muaj qhov cuam tshuam loj rau kev sib txuas ntawm cov fasteners. Raws li cov txheej txheem kev cai, qhov kam rau siab ntawm threads yuav muab faib ua 6H, 7H, thiab lwm yam. Coarse xov muaj zoo universality thiab interchangeability, haum rau kev sib txuas zaus; Cov xov zoo muaj qhov ua tau zoo los tiv thaiv loosening thiab tsim nyog rau cov xwm txheej uas yuav tsum tau ua kom muaj kev vibrations loj thiab cuam tshuam.
6. Cov lus qhia tshwj xeeb
Cov specifications ntawm fasteners feem ntau muaj xws li ob tsis: txoj kab uas hla thiab ntev. Thaum xaiv cov fasteners, nws raug nquahu kom xaiv txoj kab uas hla thiab qhov ntev ntawm cov qauv kev qhia tshwj xeeb kom txo cov khoom muag thiab cov nqi tsim khoom. Nyob rau tib lub sij hawm, rau kev xaiv ntawm txoj kab uas hla, thawj series ntawm qhov tseem ceeb yuav tsum tau xaiv kom ntau li ntau tau los txhim kho lub universality thiab interchangeability ntawm fasteners.
Hauv cov ntsiab lus, fasteners, ua cov khoom tseem ceeb rau kev sib txuas thiab kho qhov chaw, ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Los ntawm kev nkag siab txog kev faib tawm, kev xaiv cov hauv paus ntsiab lus, thiab cov kev tsis sib xws ntawm cov fasteners, peb tuaj yeem xaiv thiab siv cov fasteners zoo dua. Qhov ntawd xaus kev sib koom hnub no. Ua tsaug ntau rau koj mloog thiab nyeem.
