Hauv kev tsim khoom lossis kev sib dhos, tab sis tshwj xeeb tshaj yog nyob rau hauv cov ntawv hlau fabrication kev lag luam, xaiv txoj cai fasteners yog qhov tseem ceeb. Muaj ntau ntau hom fasteners nyob rau hauv kev ua lag luam, txhua tus tsim los rau ib daim ntawv thov tshwj xeeb thiab cov khoom siv, thiab kev xaiv txoj cai tuaj yeem txhim kho qhov ruaj khov, lub zog, thiab qhov zoo ntawm koj cov khoom. Cov lus qhia hauv qab no tuaj yeem pab koj xaiv cov fasteners tsim nyog rau koj cov kev xav tau.
Xav txog cov ntaub ntawv thiab ib puag ncig
Ib puag ncig sib txawv thiab kev siv muaj cov kev xav tau sib txawv rau cov fasteners. Piv txwv li, nyob rau hauv ib puag ncig sab nraum zoov, fasteners yuav tsum muaj kev tiv thaiv corrosion zoo los tiv thaiv kev yaig ntawm cua, nag, thiab ntau yam tshuaj. Nyob rau hauv qhov kub thiab txias ib puag ncig, fasteners yuav tsum muaj peev xwm tiv taus huab cua kom ntseeg tau qhov kev ntseeg tau ntawm kev sib txuas.
Nkag siab txog Load thiab Stress Requirements
Qhov tseeb ntawm qhov loj thiab qhov tshwj xeeb kuj yog ib qho tseem ceeb hauv kev xaiv cov fasteners. Kev thauj khoom thiab kev ntxhov siab ntawm lub fastener yog qhov tseem ceeb hauv kev xaiv. High-strength bolts los yog fasteners yog qhov tseem ceeb rau kev siv lub luag haujlwm hnyav, thaum cov khoom sib zog tsuas yog xav tau cov qauv ntsia hlau lossis rivets. Nco ntsoov xyuas cov load-bearing specifications thaum xaiv kom tsis txhob muaj kev nyab xeeb.
Ntsuas hom fastener kom tau raws li qhov xav tau los ua ke
Ntau hom fasteners tuaj yeem siv rau ntau lub hom phiaj sib dhos. Piv txwv li, DIN 931 hexagonal taub hau ib nrab xov bolts yog dav siv nyob rau hauv machinery manufacturing, kev tsim kho thiab lwm yam teb; DIN 933 hexagonal taub hau bolts yog tsim rau cov ntawv thov uas xav tau kev sib txuas xov tag nrho; DIN 6921 hexagonal flange bolts muaj lub ntsej muag loj dua thiab tuaj yeem muab cov teebmeem nruj dua; DIN 934 hexagonal txiv ntseej yog siv nrog bolts; DIN 985 nylon xauv ceev tuaj yeem tiv thaiv kom xoob; DIN 439 nyias hexagonal txiv ntseej yog tsim rau lub sijhawm uas muaj qhov txwv; DIN 7991 hexagonal countersunk screws muaj lub taub hau uas tso rau hauv qhov chaw mounting kom lub ntsej muag zoo; kuj tseem muaj DIN 965 cross recessed lauj kaub taub hau screws, DIN 125 tiaj tus ntxhua khaub ncaws, DIN 9021 loj washers, DIN127 caij nplooj ntoos hlav ntxhua khaub ncaws, thiab lwm yam. Bolts thiab ceev yog hloov tau thiab siv tau, haum rau cov ntawv thov uas yuav tsum tau disassembly thiab txij nkawm.
Xav txog kev zoo nkauj thiab kev kho saum npoo
Xaiv qhov kev kho saum npoo uas ua kom tiav lossis sib npaug ntawm cov khoom siv tuaj yeem ua kom zoo dua qub thiab ua haujlwm zoo. Tshwj xeeb tshaj yog rau cov ntaub ntawv raug, kev zoo nkauj thiab corrosion kuj tuaj yeem txhim kho los ntawm ntau yam kev kho deg, xws li zinc, nickel, lossis anodized txheej.
Xav txog cov txheej txheem installation thiab cov nqi
Kev yooj yim ntawm kev teeb tsa thiab tus nqi kuj tseem ceeb heev. Piv txwv li, tus kheej tapping screws tuaj yeem ua rau cov txheej txheem sib dhos yooj yim vim tias lawv tsis tas yuav tsum tau drilling ua ntej. Cov cuab yeej siv hluav taws xob tuaj yeem siv rau rivets thiab bolts, uas tuaj yeem ua kom nrawm rau kev sib dhos rau ntau lawm, tab sis yuav ua rau qee tus nqi pib.
Ua qhov kev xaiv zoo
Xaiv cov fasteners txoj cai tuaj yeem xyuas kom meej tias cov khoom ua tiav kev ua haujlwm zoo, ua haujlwm ntev, thiab zoo li. Txoj kev xaiv fastener thaum kawg pab txhim kho tag nrho cov khoom zoo thiab kev ntseeg siab ntawm cov khoom tiav, ua kom cov neeg siv kev txaus siab thiab kev koom tes ntev.
