GB / T 5783-2016 "Hexagon Lub Taub Hau Bolts nrog GB / T 5782-2016" Hexagon Lub Taub Hau Lwj
Yog li ntawd, hauv cov kev ntsuas hauv qab no, nws tsuas yog tsim nyog los tham txog qhov sib txawv ntawm GB / T 5780-2016 "hexagon taub hau".
2. Txawv cov khoom kawm qib:
Cov khoom lag luam qib tau muab faib ua A, B thiab C Qib. Cov khoom lag luam yog txiav txim siab los ntawm qhov loj me. Ib qib yog qhov tseeb tshaj plaws, thiab C Qib yog qhov tsawg tshaj yog qhov tseeb.
GB / T 5780-2016 "Hexagon lub taub hau Bolts C Bolts CUCK" stipulates lub C Qib Precision Bolts.
GB / T 5782-2016 "Hexagon taub hau Bolts" stipulates cov bolts nrog qib a thiab qib b precision.
Nyob rau hauv GB / T 5782-2016 "Lub taub hau Hexagon" yog siv rau Bolts nrog d = 1.6mm ~ L≤150mm (raws li tus nqi tsawg); Qib B yog siv rau D> 24 hli lossis bolts nrog L> 10D lossis L> 150mm (saib qhov twg yog me dua).
Raws li lub teb chaws tus qauv GB / T 3103.1-2002 "Kev zam lub pob tw, studs thiab txiv ntseej rau qib A thiab B Precision yog" 6g "; Qib kev ua siab ntev ntawm cov xov sab nraud yog "8g"; Lwm qhov seem tsis kam muaj ntau qib sib txawv raws li qhov tseeb ntawm A, B, thiab C Qib.
3. Cov khoom sib txawv cov khoom siv:
Raws li cov kev cai ntawm lub teb chaws tus qauv GB / t 3098.1-2010 lub zog ntawm lub zog ntawm lub zog ntawm 10 ℃ Muaj ib puag ncig ntawm bolts ntawm 10 ℃ Muaj ib puag ncig ntawm cov kab mob
Raws li cov kev cai ntawm lub teb chaws tus qauv GB / T 3098.6-2014 "cov khoom siv tshuab ib puag ncig ntawm 10 ℃, cov kab hlau ib puag ncig - hauv cov kab hlau ib puag ncig - hauv qab cov hlau ua los ntawm cov hlau tsis muaj raws li hauv qab no:
Bolts ua los ntawm Austenitic stainless hlau (suav nrog AR1, A3, A6 cim cov cuab yeej ua haujlwm ntawm cov hlau ua haujlwm, thiab cov khoom siv neeg ua haujlwm ntawm cov khoom lag luam
Bolts ua los ntawm C1 pab pawg MARTStitic Stainless Hlau muaj cov khoom me nyuam yaus qib 50, 70, thiab 110;
Bolts ua los ntawm C3 pab pawg Martensitic Stainless Hlau muaj cov khoom siv neeg kho tshuab ntawm 80;
Bolts ua los ntawm C4 pab pawg Martensitic Stainless hlau muaj cov khoom ntiag tug qib 50 thiab 70.
Bolts ua los ntawm F1 Martensitic Stainless hlau muaj cov khoom siv neeg kho tshuab qib 45 thiab 60.
Raws li lub teb chaws tus qauv GB / T 3098.10-1993 "cov khoom siv neeg kho tshuab ntawm cov pob tawb - bolts, studs thiab txiv ntseej thiab cov txiv ntseej":
Cov tshuab ua haujlwm ntawm bolts ua los ntawm tooj liab thiab tooj liab alloys yog: cu1, cu1, cu3, cu5, cu7;
Cov khoom siv tshuab hluav taws xob ntawm bolts ua los ntawm txhuas thiab aluminium alloys yog: Al1, Al2, AL2, AL4, AL6, AL6.
Lub teb chaws tus qauv GB / T 5780-2016 "Chav C Hexagon hzs hexts bolts nrog xov cov qib 4.6 thiab 4.8.
Lub teb chaws tus qauv GB / T 5782-2016 "Lub taub hau Hexagon" yog qhov tsim nyog rau cov xov specificions m1.6, 8.8, AN4-50, AN4-50, Qib A thiab Bu3 thiab Al4.
Qhov saum toj no yog lub ntsiab sib txawv ntawm 4 4 feem ntau siv bolts.
Hauv kev siv cov tswv yim, tag nrho-xov bolts tuaj yeem siv hloov chaw tsis muaj puv-threaded bolts tuaj yeem siv hloov ntawm qib qis bolts.
Txawm li cas los xij, tag nrho cov xov kab ntawm cov polts ntawm tib cov kev tshwj xeeb yog kim dua cov qib tsis muaj txiaj ntsig ntau dua li cov qib qis.
Yog li ntawd, nyob rau hauv ib txwm qee lub sijhawm, bolts yuav tsum tau raug xaiv raws li kev xav tau tiag tiag, thiab tsuas yog nyob rau hauv cov peev txheej tiag tiag, thiab tsuas yog hloov txhua yam ua txhaum "lossis" hloov cov siab nrog qis ".
