Fastenersyog ib hom tshuab caij uas yog siv rau fastening kev twb kev txuas thiab yog dav siv. Nws yog dav siv nyob rau hauv ntau yam lag luam, nrog rau cov tshuab, khoom siv, tsheb, nkoj, railways, txuas hniav, cov tsev, cov qauv, cov cuab yeej, cov cuab yeej, tshuaj, cov twj paj nruag, thiab cov khoom siv, thiab yog cov khoom siv dav siv ntau tshaj plaws.
Nws cov yam ntxwv muaj xws li ntau yam kev qhia tshwj xeeb, kev siv sib txawv, kev ua haujlwm siab ntawm cov qauv, serialization, thiab generalization. Yog li ntawd, qee hom fasteners nrog cov qauv hauv tebchaws uas twb muaj lawm kuj raug hu ua tus qauv fasteners lossis yooj yim raws li cov qauv.
1, Cov kev txwv uas yuav tsum tau qhia rau kev piav qhia cov fasteners muaj xws li: cov khoom npe (tus qauv), specification, khoom, qib zog, thiab kev kho deg. Piv txwv li: DIN912, M4-0.7x8, SCM435, qib 12.9, blackened.
1. Cov khoom npe (tus qauv): Lus Cim: Rau cov ntsia hlau uas tsis muaj tus qauv thiab koom nrog cov khoom tsis zoo, cov duab kos yuav tsum tau muab.
Piv txwv li, DIN912, Suav lub npe yog: Hexagon socket taub hau hau ntsia hlau, uas yog lub npe khoom.
Txawm li cas los xij, txoj hauv kev kom raug tshaj plaws tseem xav tau tus qauv naming, raws li GB70 kuj yog tib lub npe khoom; Tab sis muaj ntau qhov sib txawv ntawm qhov loj ntawm ob tus qauv.
Cov qauv kev muaj peev xwm tshaj plaws hauv ntiaj teb yog: German Standard (DIN), International Standard (ISO), Suav Tebchaws Standard (GB), American Standard (ANSI), thiab Japanese Standard (JIS).
2. Cov lus qhia tshwj xeeb, feem ntau hu ua tus qauv ntawm cov hniav *ntsia hlauntev.
Cov npe metric feem ntau siv rau cov hniav kab uas hla muaj xws li: M2, M3, M4, M5, M6, M8, M10, M12, thiab lwm yam;
Feem ntau siv hauv Teb Chaws Asmeskas muaj xws li: 4 # -40,6 # -32,8 # -32,10 # -24,1/4-20,5/ 16-18,3/8-16,1/2-13, thiab lwm yam.
Qhov ntev ntawm cov ntsia hlau yog hais txog qhov ntev ntawm cov khoom embedded. Piv txwv li, ib tug countersunk ntsia hlau yog loaded nrog tag nrho ntev, ib nrab countersunk ntsia hlau yuav tsum tau ntxiv qhov ntev ntawm ib nrab lub taub hau, thaum lub cylindrical ntsia hlau tsis suav nrog lub taub hau loj. Piv txwv li:
Rau cov lus qhia tshwj xeeb, nws yog qhov zoo tshaj los ntxiv suab rau lub npe tag nrho. Piv txwv li, M{{0}}.7x8,4 yog hais txog ib tug hniav nrog ib txoj kab uas hla ntawm 4 hli, 0.7 hais txog qhov deb ntawm 0.7 hli ntawm ob tug hniav peaks, thiab 8 hais txog mus rau qhov ntev ntawm 8mm embedded nyob rau hauv lub loaded khoom.
Lub hauv paus ntawm cov khoom siv Fastener
1, Kev ua haujlwm zoo:
1. Screw torque yuav tsum: Lub sab nraud hexagonal ntsia hlau muaj ib tug kuj loj torque, lub sab hauv hexagonal ntsia hlau muaj ib tug me me torque, thiab tus ntoo khaub lig zawj muaj ib tug me me torque (yog li ntawd, cov hom ntawm screws yog feem ntau zoo tib yam qib screws).
2. Hexagonal bolts feem ntau yog nruab nrog cov wrenches adjustable, wrenches, thiab qhib-kawg wrenches. Adjustable wrenches muaj kev sib dhos ua haujlwm tsawg tab sis tau siv dav. Haum rau ntau lub taub hau bolts. Lub wrench muaj qhov ua tau zoo tshaj plaws, tab sis nws tsis haum rau qee lub sijhawm. Tsuas yog ib lub nplhaib wrench taub hau tuaj yeem siv tau. Ob hom hex taub hau screws; Lub qhov rooj qhib qhov rooj zoo ib yam li lub qhov rooj hlais, tab sis nws tuaj yeem siv nrog lub qhov (socket) ntev. Qhov me me ntawm cov ntsia hlau hexagonal, qhov siab dua lub kaum sab xis yuav tsum tau ntawm lub hexagonal ntsia liaj qhov rooj, txwv tsis pub lub taub hau yuav yooj yim xaub thaum raug ( ciaj ntswj) quab yuam. Txhawm rau txuag cov ntaub ntawv, cov neeg Wenzhou tau tsim cov kev nyuaj siab hexagonal. Lub hexagonal ntsia hlau ntawm lub hnab yog lub teeb thiab lub teeb yuag, thiab lub thickness ntawm lub taub hau yog nyias, ua rau nws yooj yim rau quab yuam kom swb thiab lub taub hau yuav unscrewed.
3. Lub qhov (socket head screws) yuav tsum tau sib sau ua ke nrog tus yuam sij Hex. Qhov no muaj qhov yuav tsum tau ua rau lub qhov hexagonal sab hauv, vim tias cov ciaj ntswj ntswj thaum lub qhov loj dua thiab tsis tuaj yeem muab tso rau thaum lub ciaj ntswj me dua. Qhov me me ntawm lub qhov (socket) hexagonal, qhov siab dua qhov yuav tsum tau ua rau lub qhov. Rau qee qhov loj hex qhov (socket) screws, tsuav yog ib qho ntawm cov sab nraud ntawm lub qhov (socket) yog tsim nyog, lawv tuaj yeem sib sau ua ke nrog ib tug ciaj ntswj; Rau qee qhov me me hex socket screws, xws li M2 hex socket, yog hais tias tus ciaj ntswj yog ntxig me ntsis, lub qhov (socket) hex yuav plam, yog li ib sab loj me ntsis tsis tsim nyog. Yog li ntawd, sab hauv hexagonal screws ntawm M2, M2.5, thiab M3 (tshwj xeeb yog nruj nruj cov khoom) yog nquag plam thaum lub sij hawm sib dhos.
4. Cross recessed screws yog sib sau ua ke nrog lub hau ntswj thiab tsis tas yuav tsum muaj zog ntau dhau, yog li lub zog tsuas yog qib 4.8. Qee lub sij hawm, yuav tsum muaj cov ntsia hlau muaj zog, thiab tsuas yog kev kho cua sov yuav tsum tau ua.
