Casting thiab Forging yeej ib txwm ua tau cov txheej txheem hlau ua. Vim tias qhov sib txawv hauv cov txheej txheem ntawm cov txheej txheem ntawm cov duab ua thiab foos, tseem muaj ntau yam sib txawv hauv cov txheej txheem zaum kawg no los ntawm ob txoj kev ua tiav no.

Ib qho khoom siv casting yog cov khoom uas tau cam raws li tag nrho hauv pwm, nrog kev faib cov khoom tawg thiab tsis muaj kev txwv ntawm kev coj ua; Thiab kev zam txim tau nias los ntawm cov rog hauv tib txoj kev taw qhia, yog li lawv txoj kev ntxhov siab sab hauv tau muaj kev ua kom thiab tsuas yog tiv thaiv kev muag khoom siab.

Hais txog Casting:

1. Casting: Nws yog tus txheej txheem ntawm melting hlau rau hauv cov kua uas ua tau kom muaj cov khoom siv (seem) nrog cov duab ua ntej, ntau thiab tsawg thiab cov khoom Cov. Cov txheej txheem yooj yim ntawm niaj hnub tshuab ua kev lag luam.

2. Tus nqi ntawm raw cov ntaub ntawv tsim los ntawm casting yog tsawg, uas tuaj yeem ua tau zoo dua nws txoj kev lag luam rau cov kab, tshwj xeeb yog cov uas muaj cov kab txawv txawv; Nyob rau tib lub sijhawm, nws muaj kev yoog tau dav thiab kev ua tau zoo heev.

3. Casting Ntau Lawm yuav tsum tau ntau cov khoom siv (xws li hlau, ntoo, moulding cov ntaub pua chaw, moulding machine, sand xa machine, ntxuav blasting machine , cov hlau pov cov hlau, thiab lwm yam), thiab tuaj yeem tsim cov plua plav, teeb meem roj av, thiab suab nrov uas ib puag ncig qias neeg.

Casting yog ib qho ntawm cov txheej txheem ua haujlwm kub ua ntej los ntawm tib neeg, nrog keeb kwm ntawm 10000 xyoo. Nyob rau hauv 3200 BC, tooj liab qav Castings tshwm sim hauv Mesopotamia.

Nruab nrab ntawm 13th thiab 10 centuries BC, Suav tau nkag mus rau hauv lub Hav Zos Casting, nrog qib siab ntawm cov khoom siv tes ua. Cov khoom sawv cev ntawm cov khoom siv thaum ub muaj xws li 875kg Simuwu Fang Dynasty, lub yizun daim iav los ntawm Warring States lub sijhawm, thiab lub translucent daim iav los ntawm Western han dynasty.

Muaj ntau hom kev cais tawm hauv cov thev naus laus zis, uas tuaj yeem muab faib ua cov pawg hauv qab no raws li cov qauv molding:

①Cov xuab zeb dog dig

Suav nrog peb hom: ntub xuab zeb pwm, tshuab xuab zeb qhuav pwm, thiab siv cov xuab zeb tawv pwm;

②Xuab Zeb Thiab Pob Zeb Tshwj Xeeb Casting

Tshwj xeeb casting siv ntuj ntxhia xuab zeb, xws li cov pob zeb tseem ceeb (manting r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r rap rapting, khoom Casting, Ceramic casting, thiab lwm yam);

③Hlau Tshwj Xeeb Casting

Tshwj xeeb casuming siv hlau ua lub ntsiab casting cov khoom (xws li hlau pwm Casting, Siab Casting, qis dua Casting, Centrifugal Casting, thiab lwm yam).

Hais Txog Forging:

1. Forging: Kev ua tiav txoj kev uas siv zam cov tshuab ua kom zoo rau cov khoom siv hlau nplaum, ua rau lawv tsis quav ntsej nrog cov khoom siv ntau dua, cov duab, thiab ntau thiab tsawg.

2. Forging tuaj yeem tshem tawm cov ntxaij porosity thiab vuam qhov ntawm cov hlau, thiab cov khoom siv tshuab ua tau zoo dua li castings ntawm tib cov khoom siv. Rau qhov tseem ceeb nrog cov khoom lag luam siab thiab cov haujlwm ua haujlwm hnyav hauv cov tshuab, tsuas yog siv, tshwj tsis yog cov khoom siv yooj yim ntawm cov khoom siv uas tuaj yeem muab dov.

3. Forging tuaj yeem faib ua:

①Qhib Forging (Pub Pub Dawb)

Suav nrog peb hom: ntub xuab zeb pwm, tshuab xuab zeb qhuav pwm, thiab siv cov xuab zeb tawv pwm;

②Kaw hom forging

Tshwj xeeb casting siv ntuj ntxhia xuab zeb, xws li cov pob zeb tseem ceeb (manting r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r rap rapting, khoom Casting, Ceramic casting, thiab lwm yam);

③Lwm txoj kev sib koom ua ke casting

Raws li cov deformation kub, forging tuaj yeem faib ua kev zam kub (hauv qab kub (hauv qab no (hauv qab no

4. Cov ntaub ntawv forging tsuas yog siv cov hlau thiab cov hlau pleev xim rau ntau yam sib xyaw ua ke, ua raws los ntawm txhuas, magnesium, tooj liab thiab lawv cov alloys. Lub xeev thawj ntawm cov ntaub ntawv suav nrog cov pob zeb, kev noj, hmoov hlau hlau, thiab cov roj ua kua.

Qhov sib piv ntawm thaj chaw hla ntawm ib qho hlau ua ntej deformation rau kev tuag hla kev tom qab deformation yog hu ua kev zam txim piv. Qhov tseeb xaiv ntawm kev zam txim piv yog ze rau kev txhim kho cov khoom lag luam zoo thiab txo cov nqi.

Daim Ntawv Qhia Txog Kev Casting thiab Forging:

Kov - Qhov saum npoo ntawm cov nrib yuav tsum yog tuab, thaum lub saum npoo ntawm kev forging yuav tsum muaj zog dua

Yeeb yam - Lub cam khwb cia hlau ntu pom grey thiab tsaus, thaum lub ntsej muag steel seem tshwm nyiaj tau nyiaj thiab ci ntsa iab

Mloog - Mloog lub suab, kev Forging yog ntom, lub suab yog crisp tom qab ciav, thiab lub suab casting yog npub

Kev sib tsoo - Siv lub tshuab sib tsoo rau txhuam thiab saib seb cov sparks nruab nrab ntawm ob qho sib txawv (feem ntau tsis quav ntsej (feem ntau yog ci dua), thiab lwm yam
