Dab tsi yog Billets thiab lawv siv?
Billets yog cov khoom me me ntawm cov hlau txiav rau hauv cov duab thiab qhov ntau thiab tsawg, feem ntau yog puag ncig lossis square, thiab siv ntau yam kev tsim khoom. Lawv tuaj yeem pom hauv tsheb, tsheb, thiab lwm yam khoom. Billets yog siv los tsim thav duab, txaj, thiab cab rau cov tsheb thauj khoom, nrog rau cov kav dej, tuav, thiab xaim. Yog tsis muaj billets, tsheb thauj khoom thiab lwm yam khoom yuav ua tsis tau zoo. Billets yog qhov tseem ceeb rau txoj kev tsim kho thiab muab lub zog thiab ruaj khov rau tag nrho cov khoom.
Billet Parts yog dab tsi?
Billets tuaj yeem tsim los ntawm ntau hom hlau lossis alloys, tab sis txhuas, hlau, thiab magnesium yog cov khoom siv ntau tshaj plaws. Billets yog tsim los ntawm kev nruam casting los yog kub dov. Nyob rau hauv nruam casting, molten hlau yog poured rau hauv pwm, solidifying nws mus rau hauv ib tug semi-tiav billet zoo. Lub billet yog tom qab ntawd rov ua dua thiab dhau los ntawm cov txheej txheem ntawm cov menyuam yaus uas maj mam txo nws cov ntu ntu mus rau qhov xav tau loj. Ntawm qhov tod tes, kub dov muaj cua sov lub billet rau qhov kub siab tshaj nws cov recrystallization point ua ntej dhau nws los ntawm cov chais. Cov txheej txheem no tso cai rau cov hlau deform plastically, uas ua rau lub ntsej muag smoother.
Puas yog Billet muaj zog dua hlau?
Hais txog lub zog, billet aluminium feem ntau suav hais tias qis dua rau cov hlau billet. Txawm li cas los xij, qhov no tsuas yog qee zaum qhov xwm txheej. Billet aluminium tuaj yeem muaj zog dua li steel hlau hauv qee qhov. Billet aluminium yog softer dua billet steel, uas txhais tau hais tias nws tuaj yeem yooj yim deformed nyob rau hauv siab loads, muab nws muaj peev xwm nqus tau ntau zog. Billet aluminium feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj siab loads, xws li hauv kev tsim dav hlau. Billet steel, ntawm qhov tod tes, yog ib qho nyuaj thiab tsis tshua muaj deform. Txawm li cas los xij, nws yog qhov yooj yim dua rau kev tawg thiab tawg hauv qhov hnyav hnyav. Kev xaiv ntawm cov khoom kawg yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom xav tau ntawm cov khoom tiav.
Billet Engine Block yog dab tsi?
Ib lub cav hlau thaiv yog ib hom cav thaiv tshuab los ntawm ib qho ntawm cov hlau es tsis txhob muab pov tseg. Billet blocks feem ntau yog ua los ntawm cov hlau zoo hu ua billet, uas yog ruaj thiab muaj zog. Billet cav blocks muaj ntau qhov zoo dua li cov tsoos cam khwb cia. Lawv nruj dua thiab tsis tshua muaj kev cuam tshuam thaum lub sijhawm ua haujlwm siab. Billet blocks tuaj yeem tsim nrog nruj dua, ua rau muaj kev ua tau zoo dua thiab ua haujlwm zoo. Billet cav blocks feem ntau hnyav dua li cov cam khwb cia, uas tuaj yeem txhim kho kev lag luam roj. Txawm hais tias cov txiaj ntsig zoo li no, cov cav ntoo billet feem ntau kim dua li lawv cov cam khwb cia. Lawv feem ntau tsuas yog siv hauv cov ntawv thov kev ua haujlwm siab uas lawv cov txiaj ntsig zoo dua tus nqi nce.
Vim li cas Billets Block?
Billet blocks feem ntau yog siv rau hauv cov tshuab ua haujlwm siab vim tias lawv muaj ntau yam zoo dua cov cam khwb cia. Ua ntej, billet blocks muaj zog ntau dua thiab sib zog dua li cov cam khwb cia, uas yuav pab txo lub cav hnyav thiab txhim kho lub zog-rau-hnyav piv. Billet blocks feem ntau muaj ntau yam dav camshaft cov kev xaiv, tso cai rau kom yooj yim dua nyob rau hauv lub cav tuning. Tsis tas li ntawd, billet blocks feem ntau muaj peev xwm ua kom txias zoo dua li cov cam khwb cia, uas yog qhov tseem ceeb rau kev tiv thaiv lub cav overheating. Billet blocks tuaj yeem ua tiav nrog kev ua haujlwm nruj dua li cov cam khwb cia, txhim kho lub cav ua haujlwm. Rau tag nrho cov laj thawj no, billet blocks yog qhov kev xaiv zoo tshaj plaws rau ntau tus kws tshaj lij kev sib tw.
Yuav Ua Li Cas Billets Ua thiab Hom Hlau yog Billet?
Muaj peb yam tseem ceeb ntawm kev ua billets: nruam casting, extrusion, thiab kub dov.
Kev nruam nruam yog nchuav cov hlau molten rau hauv cov pwm txias los ua ib qho khoom siv hlau. Extrusion, ntawm qhov tod tes, koom nrog kev yuam hlau los ntawm kev tuag los tsim cov duab uas xav tau. Kub dov yog cua sov ib qho ingot los yog tawg mus rau qhov kub thiab txias thiab dhau nws los ntawm cov chais kom ua tiav cov duab xav tau.
Tom qab tsim cov billets, lawv tau ua tiav ntxiv los ntawm kev dov profile thiab kos duab. Profile dov suav nrog shaping lub billet los ntawm kev hla nws los ntawm kev tawm tsam cov chais, thaum kos duab yuav txo tau qhov chaw hla ntawm lub billet los ntawm rub nws los ntawm kev tuag. Cov khoom kawg ntawm cov txheej txheem ua billet muaj xws li bar Tshuag thiab xaim.
Hom hlau siv nyob rau hauv ib lub billet nyob ntawm nws lub hom phiaj. Steel billets, piv txwv li, yog cov khoom siv raw khoom uas yuav tsum tau ua tiav ua ntej lawv tuaj yeem siv tau. Billets tuaj yeem ua tiav los ntawm forging, extrusion, lossis dov, thiab txhua txoj kev muab cov hlau sib txawv uas tuaj yeem siv rau ntau lub hom phiaj.
xaus
Billets muaj ntau qhov zoo dua li cov tsoos cam khwb cia, nrog rau kev nruj dua thiab muaj peev xwm tsim tau nrog kev nruj dua. Txawm li cas los xij, billet cav blocks feem ntau kim dua lawv cov cam khwb cia thiab tsuas yog siv rau hauv cov ntawv thov kev ua haujlwm siab uas lawv cov txiaj ntsig ntau dua tus nqi nce. Kev nkag siab txog cov txheej txheem sib txawv ntawm kev ua billets thiab hom hlau siv hauv lawv cov khoom yog qhov tseem ceeb los xyuas kom meej tias lawv siv tau zoo hauv ntau yam kev tsim khoom.
