Cov txheej txheem ntawm aluminium alloy tuaj yeem muab faib ua casting thiab forging, yog li qhov txawv ntawm casting thiab forging yog dab tsi? Aluminium yuav qhia qhov txawv ntawmaluminium alloy tuag castingthiab aluminium alloy forging.
I. Casting:
1, Casting: yog txheej txheem ntawm melting hlau rau hauv cov kua uas ua tau raws li tej yam yuav tsum tau thiab pouring nws mus rau hauv lub casting, thiab ces tau lub casting (ib feem los yog dawb paug) nrog ib tug predetermined zoo, loj, thiab kev ua tau zoo tom qab txias thiab solidification, thiab tu. . Cov txheej txheem tseem ceeb ntawm cov tshuab niaj hnub tsim kev lag luam.
2, casting cov khoom ntawm billet nqi, rau cov duab complex, tshwj xeeb tshaj yog nrog complex sab hauv kab noj hniav ntawm qhov chaw, qhia nws kev lag luam; Nyob rau tib lub sij hawm nws yog dav adaptable, thiab muaj ib tug zoo tag nrho cov cuab yeej cuab tam.
3, tab sis cov khoom siv casting yuav tsum tau siv (xws li hlau, ntoo, roj, molding cov ntaub ntawv, thiab lwm yam) thiab cov khoom siv (xws li metallurgical rauv, xuab zeb tov khoom, molding tshuab, tub ntxhais tshuab, xuab zeb tshuab, tua blasting tshuab, cam khwb cia hlau. phaj, thiab lwm yam) ntau dua, thiab yuav tsim cov plua plav, cov pa phem thiab cov suab nrov thiab cov pa phem ntawm ib puag ncig.
4, casting yog ib qho kev paub txog tib neeg thaum ntxov ntawm cov txheej txheem hlau ua kom sov, uas muaj txog 6000 xyoo keeb kwm. 3200 BC, Mesopotamia tau tshwm sim tooj liab qws castings. Nyob nruab nrab ntawm 13 thiab 10 centuries BC, Tuam Tshoj tau nkag mus rau lub hnub qub ntawm bronze castings, cov txheej txheem tau mus txog theem siab, xws li Shang dynasty hnyav 875 kg Simuwu square tripod, Warring States Zeng Hou B zun phaj, thiab Western Han Dynasty. Daim iav translucent yog cov khoom sawv cev ntawm cov khoom qub qub. Thaum ntxov casting los ntawm kev cuam tshuam ntawm lub lauj kaub tais diav, castings feem ntau yog siv rau kev ua liaj ua teb, kev ntseeg, lub neej, thiab lwm yam ntawm cov cuab yeej siv los yog cov khoom siv, cov xim kos duab muaj zog dua. 513 BC, Tuam Tshoj pov lub ntiaj teb thawj zaug pom hauv cov ntaub ntawv sau tseg ntawm cov hlau cam khwb cia - Jin cam khwb cia tripod (kwv yees li 270 kg qhov hnyav). Nyob ib ncig ntawm lub xyoo pua 8th AD, Tebchaws Europe pib tsim cov hlau cam khwb cia. 18 xyoo pua tom qab Industrial Revolution, castings mus rau lub sijhawm tshiab ntawm kev pabcuam rau kev lag luam loj. Nyob rau hauv lub xyoo pua 20th, txoj kev loj hlob sai ntawm casting, tau tsim ductile hlau, malleable cam khwb cia hlau, ultra-low carbon stainless hlau thiab txhuas-tooj liab, aluminium-silicon,aluminium alloy, titanium, npib tsib xee-raws li alloys thiab lwm yam khoom siv hlau casting, thiab kev tsim cov txheej txheem tshiab ntawm kev yug me nyuam ntawm grey cam khwb cia hlau. Lub 50s tom qab, qhov tshwm sim ntawm ntub xuab zeb high-pressure molding, tshuaj hardening xuab zeb molding thiab core ua, tsis zoo siab molding thiab lwm yam tshwj xeeb castings, tua blasting tu, thiab lwm yam tshiab txheej txheem.
5, ntau hom casting, raws li kev cai qauv qauv muab faib ua ① zoo tib yam xuab zeb casting, nrog rau cov xuab zeb ntub, qhuav xuab zeb, thiab tshuaj hardening xuab zeb hom 3 pawg. ② Tshwj xeeb casting, raws li cov qauv tsim cov ntaub ntawv tuaj yeem muab faib ua cov pob zeb hauv av xuab zeb thiab pob zeb ua cov qauv tseem ceeb ntawm cov khoom siv tshwj xeeb (xws li fusion casting, av nplaum casting, casting plhaub, tsis zoo siab casting, khoom casting, ceramic casting, thiab lwm yam. .) thiab hlau ua cov ntaub ntawv tseem ceeb ntawm cov casting tshwj xeeb (xws li hlau casting, siab casting, nruam casting, low-pressure casting, centrifugal casting, etc.) ob pawg.
6, txheej txheem casting feem ntau suav nrog: ① casting (kom cov kua hlau ua lub thawv ntim khoom) kev npaj, casting raws li cov ntaub ntawv siv tau muab faib ua xuab zeb, hlau, ceramic, av nplaum, hom graphite, thiab lwm yam. tus naj npawb ntawm kev siv tuaj yeem muab faib ua hom ib zaug, hom semi-permanent, thiab hom mus tas li, kev npaj casting yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm casting; ② casting hlau melting thiab pouring, casting hlau (casting alloy) feem ntau yog cam khwb cia hlau, cam khwb cia hlau thiab cam khwb cia non-ferrous alloys; ③ casting txheej txheem thiab tshuaj xyuas, casting txheej txheem, nrog rau kev tshem tawm cov tub ntxhais thiab casting nto txawv teb chaws teeb meem, tshem tawm ntawm pouring lub qhov ncauj, shovel sib tsoo burrs thiab phi seams thiab lwm yam protrusions, raws li zoo raws li kev kho cua sov, shaping, xeb kev kho mob, thiab ntxhib machining. .

Thib ob, forging:
1, forging: yog kev siv cov tshuab forging los siv lub siab rau cov hlau hlau, kom nws ua cov yas deformation kom tau txais qee yam cuab yeej cuab tam, ib yam zoo li, thiab loj forgings ua txoj kev.
2, forging ib qho ntawm ob qhov tseem ceeb. Los ntawm forging tuaj yeem tshem tawm cov cam khwb cia hlau xoob, welded qhov, thiab forgings feem ntau zoo dua li cov khoom siv ntawm tib cov khoom siv castings. Machinery nyob rau hauv lub siab load, hnyav ua hauj lwm tej yam kev mob ntawm qhov tseem ceeb, ntxiv rau qhov yooj yim cov duab ntawm muaj dov phaj, profile los yog welded qhov chaw, ntau forgings.
3, forging raws li txoj kev tsim tuaj yeem muab faib ua ① qhib forging (free forging). Kev siv cov kev cuam tshuam los yog siab ua rau cov hlau nyob rau sab sauv thiab qis dua ob qho tib si tiv thaiv cov hlau (anvil) ntawm qhov deformation kom tau txais qhov yuav tsum tau forgings, feem ntau yog phau ntawv forging thiab mechanical forging ob. ② Kaw hom forging. Hlau billet nyob rau hauv ib tug tej yam zoo ntawm lub forging tuag chamber siab deformation thiab tau forgings, yuav muab faib ua tuag forging, txias taub hau, teb forging, extrusion, thiab lwm yam ... Forging los ntawm deformation kub yuav muab faib ua kub forging (ua kub siab dua. dua li qhov kub ntawm recrystallization ntawm cov hlau billet), sov forging (tsawg dua qhov kub ntawm recrystallization) thiab txias forging (chav kub).
4, forging cov ntaub ntawv feem ntau yog carbon steel thiab alloy hlau ntawm ntau yam compositions, ua raws li txhuas, magnesium, titanium, tooj liab, thiab nws alloys. Thawj lub xeev ntawm cov khoom yog bar, ingot, hlau hmoov, thiab kua hlau. Qhov sib piv ntawm qhov sib npaug ntawm qhov chaw ntawm cov hlau ua ntej deformation thiab qhov chaw tuag hla ntu tom qab deformation yog hu ua forging ratio. Qhov kev xaiv raug ntawm forging piv muaj ntau yam ua nrog kev txhim kho cov khoom zoo thiab txo cov nqi.
