5. Bolt Identification
6. Cov qhab nia, Cov qhab nia ua haujlwm, thiab lwm yam.
1. Cov cim cim: Rau hexagonal bolts thiab screws (xov txoj kab uas hla> 5mm), cov cim yuav tsum tau ua rau saum npoo ntawm lub taub hau siv cov ntawv tsa los yog rov ua dua, lossis nyob rau sab ntawm lub taub hau siv cov ntawv sau. Qhov no suav nrog qib kev ua tau zoo thiab cov qhab nia ntawm cov chaw tsim khoom. Rau cov pa roj carbon steel: Lub zog qib kev cim npe yog tsim los ntawm ob pawg ntawm cov lej sib cais los ntawm "·". Lub ntsiab lus ntawm tus lej ua ntej "·" hauv cov cim cim qhia tias lub zog tensile nominal. Piv txwv li, "4" hauv qib 4.8 qhia tias lub zog tensile nominal ntawm 400N / mm2, lossis 1/100 ntawm qhov ntawd. Lub ntsiab lus ntawm tus lej tom qab "·" nyob rau hauv cov cim cim qhia tias qhov sib piv ntawm qhov sib piv ntawm qhov sib piv ntawm qhov taw tes nominal los yog lub zog nominal rau lub zog tensile lub zog. Piv txwv li, qhov taw tes tawm ntawm cov khoom qib 4.8 yog 320N / mm2. Stainless hlau cov khoom muaj zog qib cov cim yog tsim los ntawm ob qhov sib cais los ntawm "-". Lub cim ua ntej "-" nyob rau hauv lub cim cim qhia cov khoom, xws li A2, A4, thiab lwm yam. Lub cim tom qab lub "-" qhia lub zog, xws li A2-70.
2). Qib: Rau carbon steel, metric bolt mechanical kev ua tau zoo qib tuaj yeem muab faib ua 10 qib kev ua haujlwm: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Stainless hlau muab faib ua peb pawg: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (zeeg).
7. Kev kho deg
Kev kho deg yog tsuas yog ua kom muaj kev tiv thaiv corrosion, thiab qee qhov kuj xav txog xim, yog li nws yog tsuas yog rau cov khoom siv carbon steel, uas feem ntau yuav tsum tau kho saum npoo. Cov kev kho mob saum npoo muaj xws li blackening, galvanizing, tooj liab plating, npib tsib xee plating, chrome plating, nyiaj plating, kub plating, dacromet, kub-dip galvanizing, thiab lwm yam.; muaj ntau hom galvanizing, xws li xiav thiab dawb zinc, xiav zinc, dawb zinc, daj zinc, dub zinc, ntsuab zinc, thiab lwm yam, thiab lawv kuj tau muab faib ua ib puag ncig tus phooj ywg thiab tsis yog ib puag ncig tus phooj ywg. Txhua pawg muaj ntau txheej txheej thicknesses kom tau raws li qhov sib txawv ntawm cov tshuaj tsuag ntsev.
Txheej txheem cej luam ntawm Automotive Standard Parts Products
1). Txheej txheem cej luam ntawm Automotive Standard Parts
Automotive txheem qhov chaw muaj ntau yam ntau yam thiab yog siv nyob rau hauv lub tshwj xeeb zus tau tej cov ntau yam Cheebtsam thiab qhov chaw ntawm lub tsheb, nrog rau kev sib txuas thiab sib dhos ntawm ntau yam subsystems los tsim tag nrho lub tsheb. Qhov zoo ntawm cov txheej txheem muaj feem cuam tshuam rau tag nrho qhov zoo thiab kev ua haujlwm ntawm cov cuab yeej siv tshuab, thiab cov tuam txhab tsheb feem ntau muaj cov txheej txheem tshuaj xyuas nruj thiab cov qauv ntawv pov thawj rau cov khoom siv fastener. Kev lag luam loj loj ntawm kev lag luam automotive muab qhov chaw loj hlob rau cov khoom lag luam automotive. Raws li kev txheeb cais, lub teeb lub luag haujlwm lossis lub tsheb neeg caij tsheb yuav tsum muaj txog 50kg (kwv yees li 5,000 daim) ntawm cov qauv, thaum lub tsheb lag luam nruab nrab lossis hnyav hnyav yuav tsum muaj txog 90kg (txog 5,710 daim).
2). Automotive Standard Parts Numbering
Txhua lub tuam txhab tsim hluav taws xob tseem ceeb hauv kev lag luam tsheb siv tus qauv "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013) los tsim cov kev qhia tshwj xeeb rau kev lag luam tus qauv lej, thiab cov ntsiab lus tseem zoo ib yam txawm tias muaj kev hloov pauv.
Automotive standard qhov chaw numbering feem ntau muaj 7 qhov chaw, nyob rau hauv kev txiav txim:
- Ntu 1: Automotive txheem qhov chaw feature code;
- Ntu 2: Ntau yam code;
- Ntu 3: Hloov code (yeem);
- Ntu 4: Dimensional specification code;
- Ntu 5: Mechanical kev ua tau zoo lossis cov khoom siv code;
- Ntu 6: Txoj Cai Kho Nto;
- Ntu 7: Kev faib cov lej (yeem).
Piv txwv li: Q150B1250TF61 sawv cev rau hexagonal taub hau ntsia liaj qhov rooj nrog ib tug xov specification ntawm M12, ib tug ntsia liaj qhov rooj ntev ntawm 50 hli, ib tug kev kawm qib ntawm 10.9, thiab ib tug uas tsis yog-electrolytic zinc plating (silver-grey) txheej. Txoj kev sawv cev yog raws li nram no:
