Txhua tus uas tau tuav lub hau ntswj lossis rauj ntawm lawv txhais tes paub tias lub fastener yog dab tsi. Qhov kev txhais no haum rau txhua yam khoom siv hlau uas tso cai rau koj txuas ob ntu ua ke. Daim ntawv teev npe loj no muaj cov ntsia hlau, tus kheej tapping screws, bolts, thauj tog rau nkoj, txiv ntseej, ntxhua khaub ncaws thiab ntau ntau yam khoom siv. Tag nrho cov no tau siv dav hauv kev lag luam.

Txhua qhov txuas yog nyob ntawm ib pawg lossis lwm tus: kev tsim kho, rooj tog zaum, kev tsheb ciav hlau, tsheb lossis kev siv dav dav. Txhua qhov kev xaiv muaj nws cov kev faib ntxiv. Qhov ntau hom kev tsim kho fasteners. Qhov no suav nrog bolts, screws, ntxhua khaub ncaws … feem ntau, txhua yam uas peb siv thaum peb sib sau ua ke phau ntawv txee lossis rooj nrog peb tus kheej tes.

Txhua yam khoom siv yuav tsum ua tau raws li qee qhov kev xav tau. Muaj ntau tus qauv sib txawv, uas qhia txog cov yam ntxwv ntawm fasteners. GOST 27017-86 piav qhia txog hom thiab npe ntawm txhua yam khoom siv kho vajtse. Thiab tom qab ntawd rau txhua yam khoommuaj ib tug qauv uas qhia tag nrho cov yuav tsum tau.

Txhua qhov txuas nrog rau cov khoom siv yog ua los ntawm hlau. Nws tuaj yeem yog tooj dag, carbon hlau lossis stainless hlau. Yog tias tsim nyog, txheej txheej ntxiv yog siv los tiv thaiv cov hlau los ntawm corrosion. Tab sis nws raug tso cai siv kho vajtse yam tsis muaj txheej tiv thaiv. Feem ntau koj tuaj yeem pom dub tus kheej tapping ntsia hlau lossis ntsia hlau - qhov no yog phosphated lossis oxidized txheej. Fasteners uas tau txais kev kho mob ntxiv galvanizing zoo li ntxim nyiam dua.

Txhua lub tsev kho vajtse tuaj yeem muab faib ua ob peb pawg. Xav txog txhua qhov sib cais.

Metric fasteners

pab pawg no suav nrog txhua yam ntawm cov ntsia hlau, bolts, studs, txiv ntseej thiab ntxhua khaub ncaws. Lawv pab ncaj qha rau detachable kev twb kev txuas ntawm qhov chaw. Kev tsim cov fasteners muab rau kev sib txuas lus ntawm cov xov sab nraud ntawm cov ntsia hlau lossis ntsia liaj qhov rooj rau cov xov sab hauv ntawm cov txiv ntoo. Yog li ntawd, txhua qhov loj muaj nws tus kheej counterpart. Lub tshuab ntxhua khaub ncaws pab kho qhov khi ntxiv.

Anchor fasteners

Qhov no suav nrog cov khoom siv uas siv rau cov khoom hnyav. Lub fastener no yog siv thaum nws yuav tsum tau rigidly kho lub tsev qauv, xws li lub qhov rais los yog ib tug ya ntawm ntaiv. Lub thauj tog rau nkoj muaj ob yam. Qhov chaw spacer yog qhov tseem ceeb tshaj plaws. Nws yog nws leej twg, hloov ntawm loads, tso cai rau koj tuav tag nrho cov qauv. Ib txoj hauj lwm sib cais yog cov khoom siv tshuaj lom neeg. Cov fastener no feem ntau siv thaum mountingntaiv. Nws yog raws li kev sau cov voids nrog cov khoom siv tawv tawv.

Txoj hlua khi

Nws yog siv rau phab ntsa thaum nws tsim nyog los dai khoom hnyav. Ib tug dowel yog xub muab tso rau hauv lub qhov npaj, thiab ces ib tug ntsia hlau yog screwed rau hauv. Nws hloov tawm ib tug ncaj ncaj mount. Niaj hnub no, dowels yog (feem ntau) ua los ntawm cov yas los yog cov khoom zoo sib xws.

Secrets

Lub fastener no txawv ntawm cov ntsia hlau thiab bolts los ntawm threading uas tso cai rau koj txiav cov xov sab hauv hauv qhov chaw. Siv dav hauv kev tsim kho. Ua rau cov khoom sib txawv. Yuav tsum tsis txhob siv cov ntsia hlau ntoo lossis phab ntsa ntub dej thaum ua haujlwm nrog cov yas lossis hlau.

Screws

Lawv muaj tib txoj cai ntawm kev ua raws li tus kheej tapping screws, tab sis yog siv rau cov ntaub ntawv softer. Tus pas nrig yog ib nrab xov, ua los ntawm cov hlau tsis tshua muaj zog.

Rivets

Pab rau kev txuas mus tas li ntawm cov khoom. Siv nyob rau hauv ntau yam teb, nyob rau hauv kev tsim cov rooj tog thiab txawm nyob rau hauv lub railway kev lag luam.

Txhua tus fasteners muaj lawv tus kheej lub zog. Los ntawm nws koj tuaj yeem txiav txim siab qhov twg nws zoo dua los siv cov khoom. Nyob rau hauv tsos, screws, bolts, screws thiab self-tapping screws yog heev zoo sib xws. Lawv muaj ib lub taub hau ntawm ntau yam duab thiab ib tug ncej uas cov xov yog tag nrho los yog ib feem siv. Lub hau ntswj thiab tus kheej-tapping ntsia hlau kawg nrog rau qhov kawg taw tes, nrog kev pab los ntawm cov khoom uas hais txog yog ntsia hlau rau hauv cov khoom. Cov duab ntawm lub taub hau tuaj yeem yog semicircular, tiaj tus, square, hexagonal, countersunk lossis semi- countersunk. Rau qhov yooj yim ntawm screwing ntawm lub kaus mom, tshwj xeeb slots yog txiav nyob rau hauv daim ntawv ntawm ib tug ntoo khaub lig los yog ib tug sawb. Qee lub sij hawm tsis yog tus qauv txiav yog tsim rau kev tiv thaiv ntxiv, uas yuav tsum tau siv cov cuab yeej tshwj xeeb.
