Kev Taw Qhia Txog Cov Khoom Siv Txuas-2

4. Daim duab qhia txog qhov chaw ntsia hlau

5. Kev Txheeb Xyuas Bolt

6. Cov Cim, Cov Qib Kev Ua Tau Zoo, thiab lwm yam.

1. Cov Cim: Rau cov ntsia hlau hexagonal thiab cov ntsia hlau (txoj xov txoj kab uas hla > 5 hli), cov cim yuav tsum tau ua rau saum npoo ntawm lub taub hau siv cov ntawv tsa lossis recessed, lossis ntawm sab ntawm lub taub hau siv cov ntawv recessed. Qhov no suav nrog cov qib kev ua tau zoo thiab cov cim ntawm cov chaw tsim khoom. Rau cov hlau carbon: Cov lej cim qib zog yog tsim los ntawm ob pawg lej sib cais los ntawm "·". Lub ntsiab lus ntawm tus lej ua ntej "·" hauv cov lej cim qhia txog lub zog tensile nominal. Piv txwv li, "4" hauv qib 4.8 qhia txog lub zog tensile nominal ntawm 400N / mm2, lossis 1/100 ntawm qhov ntawd. Lub ntsiab lus ntawm tus lej tom qab "·" hauv cov lej cim qhia txog qhov sib piv ntawm yield-to-tensile, uas yog qhov sib piv ntawm qhov chaw yield lossis lub zog yield nominal rau lub zog tensile nominal. Piv txwv li, qhov chaw yield ntawm cov khoom qib 4.8 yog 320N / mm2. Cov cim qib zog ntawm cov khoom stainless hlau yog tsim los ntawm ob ntu sib cais los ntawm "-". Lub cim ua ntej "-" hauv cov lej cim qhia txog cov khoom siv, xws li A2, A4, thiab lwm yam. Lub cim tom qab "-" qhia txog lub zog, xws li A2-70.

2). Qib: Rau cov hlau carbon, cov qib metric bolt mechanical performance tuaj yeem muab faib ua 10 qib kev ua tau zoo: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Cov hlau tsis xeb tau muab faib ua peb pawg: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (ferritic).

7. Kev Kho Mob Nto

Kev kho qhov chaw feem ntau yog ua kom muaj kev tiv thaiv xeb ntau dua, thiab qee qhov kuj xav txog xim, yog li nws feem ntau yog rau cov khoom siv hlau carbon, uas feem ntau xav tau kev kho qhov chaw. Kev kho qhov chaw feem ntau suav nrog kev ua kom dub, galvanizing, tooj liab plating, nickel 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 hom uas zoo rau ib puag ncig thiab tsis zoo rau ib puag ncig. Txhua pawg muaj ntau txheej tuab kom tau raws li cov kev cai sib txawv ntawm kev sim ntsev tsuag.

Kev Txheeb Xyuas Txog Cov Khoom Siv Txheem Tsheb

1). Txheej txheem cej luam ntawm Cov Khoom Siv Txheem Tsheb

Cov khoom siv txheem ntawm tsheb muaj ntau yam thiab siv rau hauv kev tsim khoom tshwj xeeb ntawm ntau yam khoom 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 khoom txheem muaj qhov cuam tshuam tseem ceeb rau qhov zoo thiab kev ua tau zoo ntawm cov khoom siv kho tshuab, thiab cov chaw tsim khoom tsheb feem ntau muaj cov txheej txheem tshuaj xyuas nruj thiab cov qauv ntawv pov thawj rau cov txheej txheem muab khoom siv. Kev lag luam loj ntawm kev lag luam tsheb muab qhov chaw loj hlob rau cov khoom siv txheem ntawm tsheb. Raws li cov ntaub ntawv txheeb cais, lub tsheb sib zog lossis lub tsheb thauj neeg xav tau txog 50kg (kwv yees li 5,000 daim) ntawm cov khoom txheem, thaum lub tsheb lag luam nruab nrab lossis hnyav xav tau txog 90kg (kwv yees li 5,710 daim).

2). Cov lej ntawm cov khoom siv hauv tsheb

Txhua lub chaw tsim khoom siv cav loj hauv kev lag luam tsheb siv tus qauv "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013) los tsim cov lus qhia rau cov lej khoom lag luam, thiab cov ntsiab lus tseem zoo ib yam txawm tias muaj kev hloov pauv.

Cov lej ntawm cov khoom siv hauv tsheb feem ntau muaj 7 qhov, raws li nram no:

- Ntu 1: Cov lej qhia txog cov khoom siv hauv tsheb;
- Ntu 2: Tus lej ntau yam;
- Ntu 3: Hloov tus lej (xaiv tau);
- Ntu 4: Cov lej qhia txog qhov ntev;
- Ntu 5: Kev ua tau zoo ntawm lub tshuab lossis cov lej khoom siv;
- Ntu 6: Tus lej kho qhov chaw;
- Ntu 7: Tus lej faib tawm (xaiv tau).

Piv txwv li: Q150B1250TF61 sawv cev rau lub hau hexagonal bolt nrog cov xov M12, qhov ntev ntawm 50 hli, qib kev ua tau zoo ntawm 10.9, thiab txheej zinc tsis-electrolytic (silver-grey). Txoj kev sawv cev yog raws li nram no:
