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. Kev xaiv cov khoom siv muaj zog bolt
Kev xaiv kom raug ntawm cov ntaub ntawv fastener hauv kev tsim khoom fastener yog ib qho tseem ceeb, vim hais tias kev ua tau zoo ntawm fasteners yog ze rau nws cov khoom. Cold heading steel yog steel rau fasteners nrog siab sib hloov ua los ntawm cov txheej txheem txias taub hau. Vim nws yog tsim los ntawm cov hlau yas ua nyob rau hauv chav tsev kub, qhov deformation tus nqi ntawm txhua feem yog loj, thiab deformation ceev kuj siab. Yog li ntawd, qhov kev ua tau zoo ntawm cov khoom siv txias txias steel yog nruj heev.
(1) Yog tias cov ntsiab lus carbon siab dhau lawm, qhov kev ua haujlwm txias txias yuav raug txo, thiab yog tias cov ntsiab lus carbon tsawg dhau, nws yuav tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv ntawm cov khoom.
(2) Manganese tuaj yeem txhim kho permeability ntawm hlau, tab sis ntxiv ntau dhau yuav ntxiv dag zog rau cov qauv matrix thiab cuam tshuam rau kev ua haujlwm txias.
(3) Silicon tuaj yeem ntxiv dag zog rau ferrite kom txo tau cov khoom txias thiab cov khoom elongation.
(4) Txawm hais tias boron keeb muaj cov txiaj ntsig ntawm kev txhim kho cov permeability ntawm hlau, nws tseem yuav ua rau muaj kev nce hauv brittleness ntawm hlau. Cov ntsiab lus boron ntau dhau yog qhov tsis zoo rau cov khoom ua haujlwm xws li bolts, screws thiab studs uas yuav tsum muaj cov khoom zoo txhua yam.
(5) Lwm yam impurity cov ntsiab lus, lawv lub neej yuav ua rau muaj kev sib cais raws li cov ciam teb, uas ua rau lub embrittlement ntawm grain ciam teb, thiab kev puas tsuaj rau cov cuab yeej ntawm cov hlau yuav tsum raug txo kom ntau li ntau tau.
