Bolts ua los ntawm high-strength steel, los yog bolts uas yuav tsum tau ib tug loj preload quab yuam, yuav hu ua high-strength bolts. Lub zog muaj zog bolts tau dav siv rau kev sib txuas ntawm Cov Txuas Txuas, cov ntsia hlau, kev kub siab thiab cov khoom siv ultra-siab. Qhov tawg ntawm cov bolts no feem ntau yog cov pob txha tawg. Rau lub zog muaj zog bolts siv nyob rau hauv cov khoom siv ultrahigh siab, txhawm rau xyuas kom lub ntim ntim, yuav tsum muaj lub zog loj.
Qhov txawv ntawm lub zog muaj zog bolts thiab zoo tib yam bolts:
Cov khoom siv ntawm cov bolts zoo tib yam yog ua los ntawm Q235 (ie A3).
Cov khoom siv ntawm cov bolts muaj zog yog 35 # steel lossis lwm yam khoom siv zoo, uas yog cov cua sov kho tom qab tsim los txhim kho lub zog.
Qhov sib txawv ntawm ob yog lub zog ntawm cov khoom siv.
Los ntawm raw cov ntaub ntawv:
Lub zog muaj zog bolts yog ua los ntawm cov ntaub ntawv muaj zog. Cov ntsia hlau, txiv ntseej thiab lub tshuab ntxhua khaub ncaws ntawm lub taub hau muaj zog yog ua los ntawm cov hlau muaj zog, feem ntau siv 45 steel, 40 boron steel, 20 manganese titanium boron steel, 35CrMoA thiab lwm yam. Ordinary bolts feem ntau yog ua los ntawm Q235 (A3) steel.
Los ntawm qib zog:
High-strength bolts feem ntau yog siv nyob rau hauv ob qib zog ntawm 8.8s thiab 10.9s, ntawm uas 10.9 yog feem ntau. Ordinary bolt lub zog qib qis, feem ntau 4.8, 5.6.
Los ntawm qhov pom ntawm cov yam ntxwv quab yuam: lub zog muaj zog bolts siv ua ntej nro thiab hloov lwm lub zog los ntawm kev sib txhuam. Kev sib txuas ntawm cov ntsia liaj qhov rooj cia siab rau ntawm lub bolt shear tsis kam thiab lub qhov phab ntsa siab kom hloov cov shear quab yuam, thiab cov pretension generated thaum zawm cov txiv ntseej me me, nws cov cawv tuaj yeem tsis quav ntsej, thiab lub zog siab bolt ntxiv rau nws cov khoom siv siab, kuj exerts. ib tug loj pretension ntawm lub ntsia liaj qhov rooj, yog li ntawd lub extrusion siab ntawm lub connecting cov tswv cuab, thiaj li hais tias muaj ib tug ntau ntawm kev sib txhuam perpendicular rau cov kev taw qhia ntawm lub ntsia hlau. Tsis tas li ntawd, lub pretension, anti-slip coefficient thiab hom hlau ncaj qha cuam tshuam rau cov kabmob muaj peev xwm ntawm cov bolts muaj zog.
Raws li cov yam ntxwv quab yuam, nws tuaj yeem muab faib ua hom siab thiab kev sib txhuam. Ob txoj kev suav yog txawv. Qhov tsawg kawg nkaus specification ntawm high-strength bolts yog M12, feem ntau siv M16 ~ M30, kev ua tau zoo ntawm cov bolts loj yog tsis ruaj khov, thiab yuav tsum tau ua tib zoo siv rau hauv kev tsim.
Los ntawm kev siv:
Lub bolt kev twb kev txuas ntawm lub ntsiab Cheebtsam ntawm lub tsev qauv yog feem ntau txuas nrog high-strength bolts. Cov bolts feem ntau tuaj yeem rov qab siv tau, cov bolts muaj zog tsis tuaj yeem rov qab siv dua. Lub zog muaj zog bolts feem ntau yog siv rau kev sib txuas mus tas li.
