Yuav ua li cas txiav txim siab qhov zoo ntawm cov titanium fasteners?
1. Daim ntawv pov thawj khoom siv (daim ntawv tseem ceeb tshaj plaws):
Daim Ntawv Qhia Txog Khoom Siv Thawj: Tus neeg muag khoom yuav tsum muab Daim Ntawv Pov Thawj Xeem Zeb (MTC) uas lub chaw tsim khoom siv titanium muab. Xyuas kom tseeb tias:
Hom: Seb nws puas yog hom pom zoo (xws li titanium ntshiab TA1 / TA2, titanium alloy TC4 / TC6 / GR5, thiab lwm yam).
Cov tshuaj lom neeg muaj pes tsawg leeg: Seb cov ntsiab lus ntawm txhua yam (tshwj xeeb tshaj yog cov ntsiab lus tseem ceeb Al, V, Fe, O, thiab lwm yam) puas nyob hauv qhov ntau thiab tsawg.
Cov khoom siv kho tshuab: Seb lub zog tensile, lub zog yield, elongation, thiab lwm yam puas ua tau raws li cov qauv.
Kev taug qab: Tus lej ntawm cov khoom siv hauv lub cub tawg yuav tsum sib xws nrog tus lej ntawm cov khoom siv raw.
2. Cov qauv khoom thiab cov ntawv pov thawj:
Ua raws li cov qauv: Cov khoom tsim tawm raws li tus qauv twg (xws li tus qauv hauv tebchaws GB / T, tus qauv tub rog hauv tebchaws GJB, tus qauv Asmeskas ASTM, tus qauv dav hlau HB, tus qauv tsheb, thiab lwm yam). Tus qauv txhais cov kev ua tau zoo.
Daim Ntawv Pov Thawj Txheej Txheem: Puas yog tus neeg tsim khoom muaj daim ntawv pov thawj zoo ISO 9001. Puas muaj daim ntawv pov thawj qib siab dua xws li AS9100, IATF 16949, ISO 13485 rau cov teb tshwj xeeb xws li aerospace thiab kev kho mob.
3. Daim Ntawv Qhia Txog Kev Tshuaj Xyuas Lub Hoobkas (COA):
Thov kom muab 'Daim Ntawv Qhia Txog Kev Tshuaj Xyuas Hoobkas' rau tib pawg khoom kom pom tias cov khoom tseem ceeb (qhov loj me, qhov nyuaj, lub zog tensile, thiab lwm yam) tau raug sim thiab yog tias cov ntaub ntawv tsim nyog.
4. Kev Pom Kev thiab Kev Kov:
Xim thiab ci ntsa iab: Cov xim ntuj ntawm titanium alloy yuav tsum yog xim grey tsaus lossis xim grey nyiaj sib xws. Cov xim tom qab anodizing yuav tsum sib xws thiab sib xws, tsis muaj paj lossis xim sib txawv. Qhov chaw yuav tsum huv, tsis muaj roj av thiab cov hlau seem.
Qhov zoo ntawm qhov chaw: Cov khoom tseem ceeb xws li cov xov thiab cov flange nto yuav tsum tsis muaj burrs, tawg, khawb, thiab pob. Qhov no tseem ceeb heev rau cov khoom siv txuas uas tiv taus kev ntxhov siab sib hloov pauv.
Lub logo thiab kev txheeb xyuas: Seb lub logo taub hau (xws li qib kev ua tau zoo, lub logo Hoobkas) puas meej thiab raug.
5. Qhov loj thiab qhov tseeb:
Qhov loj tseem ceeb: Siv cov cuab yeej xws li calipers thiab micrometers los ntsuas qhov txoj kab uas hla ntawm cov ntsia hlau, qhov loj ntawm lub taub hau, qhov tuab ntawm flange, thiab lwm yam, kom pom tias lawv puas ua tau raws li qhov kos duab lossis tus qauv kam rau ua.
Kev tseeb ntawm xov: Siv lub ntsuas xov los xyuas. Lub ntsuas GO yuav tsum tau ntsia kom du, thiab lub ntsuas NO-GO yuav tsum tsis txhob ntsia ntau tshaj 2-3 zaug. Qhov no yog qhov kev tshuaj xyuas yooj yim thiab tseem ceeb tshaj plaws.
6. Kev sim ua haujlwm ntawm lub tshuab (txheeb xyuas lub zog):
Kev ntsuas qhov nyuaj: ntsuas siv Rockwell lossis Vickers hardness tester, tus nqi hardness yuav tsum nyob hauv qhov ntau thiab tsawg tsim nyog sib raug rau qib khoom siv thiab lub xeev kho cua sov. Hardness yog qhov cuam tshuam tsis ncaj qha ntawm lub zog thiab cov nyhuv kho cua sov.
Kev Ntsuas Lub Zog Tensile/Wedge Load: Ua rau ntawm lub tshuab kuaj khoom siv thoob ntiaj teb, qhov no yog qhov kev txheeb xyuas lub zog ncaj qha tshaj plaws. Cov txiaj ntsig ntawm kev xeem (lub zog tensile, lub zog yield) yuav tsum ua tau raws li lossis tshaj qhov yuav tsum tau ua. Qhov chaw tawg yuav tsum tau saib ntawm lub hau ntswj, tsis yog ntawm cov hauv paus ntawm cov xov (kev ua cov xov tsis zoo tuaj yeem ua rau muaj kev ntxhov siab).
7. Kev sim tiv thaiv corrosion:
Kev sim tshuaj tsuag ntsev: Muab cov qauv tso rau hauv lub chamber tsuag ntsev thiab sim nws rau lub sijhawm teev tseg (xws li 96 teev, 240 teev) kom pom seb puas muaj xeb liab, xeb dawb, lossis qhov xeb ntawm qhov chaw. Titanium alloys theoretically muaj kev tiv thaiv zoo heev rau kev tsuag ntsev, tab sis qhov tsis zoo ntawm kev kho qhov chaw tuaj yeem ua rau muaj kev xeb hauv zos.
