Cov ntsiab lus ntawm High Strength Bolts
Raws li lub xeev kev ntxhov siab, nws tuaj yeem muab faib ua hom kev sib txhuam thiab lub siab: Qhov tseeb, muaj qhov sib txawv ntawm cov qauv tsim thiab kev suav.Cov kev sib txhuam hom high-strength bolts siv lub plam ntawm daim hlau raws li lub xeev txwv ntawm cov kabmob muaj peev xwm.Hom-I lub zog muaj zog bolts siv cov hlua khi ntawm cov slabs raws li lub xeev txwv, thiab kev sib txuas tsis ua haujlwm raws li lub xeev txwv ntawm cov kabmob muaj peev xwm.Kev sib txhuam siab zog bolts tsis tuaj yeem muab kev ua si tag nrho rau lub peev xwm ntawm bolts.Hauv kev siv tswv yim, kev sib txhuam hom kev sib txhuam muaj zog bolts yuav tsum tau siv rau cov qauv tseem ceeb lossis cov qauv uas muaj cov khoom hnyav, tshwj xeeb tshaj yog thaum cov loads ua rau muaj kev ntxhov siab.Nyob rau lub sijhawm no, lub peev xwm siv tsis tau siv tau siv tau los ua qhov chaw ruaj ntseg.Tsis tas li ntawd, lub siab-cov kabmob muaj zog bolts yuav tsum tau siv los txo tus nqi.
Raws li kev tsim kho tshuab, nws tau muab faib ua: torsional shear type high-strength bolt thiab loj hexagonal high-strength bolt.Lub hexagonal high-strength bolt belongs rau qib high-strength ntawm zoo tib yam screws, thaum lub torsional shear hom high-strength bolt yog ib qho kev txhim kho hom hexagonal high-strength bolt, thiaj li yuav txhim kho zoo dua.Kev tsim kho ntawm cov ntsia hlau muaj zog yuav tsum tau muab ntsia ua ntej thiab tom qab ntawd thaum kawg, thiab qhov cuam tshuam hom hluav taws xob los yog lub zog hloov hluav taws xob yuav tsum tau siv rau thawj zaug screwing ntawm high-strength bolts;Txawm li cas los xij, muaj cov kev cai nruj rau qhov kawg nruj ntawm lub zog siab bolts.Qhov kawg zawm ntawm torsional shear type high-strength bolts yuav tsum siv lub torsional shear type electric wrench, thiab qhov kawg nruj ntawm torque hom high-strength bolts yuav tsum siv lub torque hom hluav taws xob wrench.Lub hexagonal ntsia liaj qhov rooj muaj ib tug ntsia liaj qhov rooj, ib tug txiv ntseej thiab ob lub tshuab ntxhua khaub ncaws.Lub shear-type high-strength bolt muaj ib tug ntsia liaj qhov rooj, ib tug txiv ntseej thiab ib tug washer.
1. Lub siab-bearing high-strength bolt: Hom no muaj zog bolt feem ntau yog siv rau kev sib txuas ntawm cov khoom zoo li qub lossis me ntsis zawv zawg cov qauv.Nws yog qhov yuav tsum tau siv lub siab-lub zog bolt siv rau lub zog siab-cov kabmob muaj peev xwm thiab muaj zog shear tsis kam.
2. Friction-type high-strength bolt: Hom no muaj zog bolt feem ntau yog siv rau kev sib txuas ntawm lub braking system thiab cov qauv tseem ceeb bearing dynamic loads, xws li kev sib txuas ntawm hnyav crane beams thiab khoom web beams.
3. Tensile-type high-strength bolts: Qhov tseem ceeb ntawm hom no ntawm lub zog siab bolts yog tias cov bolts tsis yooj yim rau deform, tawg los yog poob rau hauv lub zog nruj, thiab lwm yam. Lawv feem ntau siv rau flange kev sib txuas ntawm lub siab. ntu.
High-strength bolts yog haum rau cov tsev loj loj, steel qauv ntawm cov nroj tsuag muaj, steel thav duab ntawm cov tsev siab, choj cov qauv, hnyav nqa machinery thiab lwm yam tseem ceeb qauv.
Raws li hom kev sib txuas, muaj peb hom hauv qab no:
(1) Kev teeb tsa thiab wiping hom high-strength bolts yog tsim rau beam-kem kev sib txuas hauv cov qauv steel, hnyav crane beam kev sib txuas hauv cov nroj tsuag, cov khoom web beam sib txuas, braking systems thiab cov qauv tseem ceeb uas muaj cov khoom hnyav.
(2) Lub siab-cov kabmob muaj zog bolts tuaj yeem siv rau kev sib txuas ntawm kev sib txuas hauv cov qauv thauj khoom zoo li qub uas tso cai rau me me ntawm zawv zawg lossis hauv cov khoom uas tsis ncaj qha dais dynamic loads.
(3) Tensile high-strength bolts muaj zog qaug zog tsis tshua muaj zog nyob rau hauv nro, thiab lawv cov kabmob muaj peev xwm tsis tau yooj yim tshaj 0.6P (P nyob rau hauv dynamic load (P yog lub tso cai axial quab yuam ntawm bolts). Yog li ntawd, nws tsuas yog haum rau siv nyob rau hauv zoo li qub. load, xws li flange pob tw thiab T-joint ntawm compression bar.
