Khoom piav qhia
hub bolts yog lub zog siab bolts uas txuas tsheb mus rau lub log. Qhov chaw sib txuas yog lub hub unit bearing ntawm lub log! Feem ntau, chav kawm 10.9 yog siv rau cov tsheb me me, chav kawm 12.9 yog siv rau cov tsheb loj! Cov qauv ntawm lub hub ntsia liaj qhov rooj feem ntau yog cov ntaub ntawv tseem ceeb knurled thiab cov ntaub ntawv threaded! Thiab lub kaus mom lub taub hau! Feem ntau ntawm T-shaped lub taub hau bolts yog siab dua 8.8 qib, uas dais qhov loj torsion txuas ntawm lub tsheb log thiab lub qag! Feem ntau ntawm ob lub taub hau log bolts yog siab dua qib 4.8, uas dais qhov sib zog torsion kev sib txuas ntawm lub plhaub sab nraud thiab lub log tsheb.
Manufacturing txheej txheem ntawm siab zog bolts
1. Spheroidizing annealing ntawm high-strength bolts
Thaum lub hexagon socket lub taub hau bolts yog tsim los ntawm cov txheej txheem txias taub hau, cov qauv qub ntawm cov hlau yuav ncaj qha cuam tshuam rau kev tsim muaj peev xwm thaum lub caij txias ua haujlwm. Yog li ntawd, cov hlau yuav tsum muaj plasticity zoo. Thaum cov tshuaj muaj pes tsawg leeg ntawm cov hlau tsis tu ncua, cov qauv metallographic yog qhov tseem ceeb ntawm kev txiav txim siab plasticity. Nws feem ntau ntseeg hais tias cov ntxhib flaky pearlite tsis haum rau kev sib sau txias, thaum lub ntsej muag zoo nkauj pearlite tuaj yeem txhim kho lub peev xwm ntawm cov yas deformation ntawm cov hlau.
Rau nruab nrab carbon steel thiab nruab nrab carbon alloy steel nrog ib tug loj npaum li cas ntawm cov high-strength fasteners, spheroidizing annealing yog ua ua ntej txias taub hau, thiaj li yuav tau uniform thiab nplua spheroidized pearlite kom zoo dua raws li qhov tseeb ntau lawm.
