Cov ntsiab lus xws li "forging," "stamping," thiab "casting" hauv cov ntsiab lus ntawmtitanium alloystxhua yam zoo li cuam tshuam rau "hlau sib sau," tab sis dab tsi raws nraim lawv sib nrug? Niaj hnub no, peb yuav pab koj kom nkag siab meej txog peb cov txheej txheem no, yog li koj tuaj yeem nkag siab yooj yim ntawm kev tsim khoom tsis zoo tom qab lawv!
I.Qhov txawv ntawm Forging thiab Casting
(1) Kev xav txawv
Casting: Cov txheej txheem no yuav tsum tau nchuav cov kua hlau ua kua rau hauv qhov ua ntej- ua pwm kab noj hniav; Tom qab txias thiab solidification, ib tug casting nrog ib tug tshwj xeeb cov duab thiab cov khoom yog tau. Tag nrho cov txheej txheem tuaj yeem raug suav hais tias yog: khoom → kua → khoom. Qhov no zoo ib yam li melting wax rau hauv cov kua, ncuav nws mus rau hauv pwm, thiab cia nws txias rau hauv cov duab uas xav tau. Forging: Forging suav nrog kev siv lub zog sab nraud (kev cuam tshuam lossis siab) rau cov hlau hauv nws lub xeev ruaj khov kom ua rau cov yas deformation, yog li tsim ib feem forged nrog cov duab tshwj xeeb, qhov ntev, thiab cov khoom. Cov txheej txheem no tuaj yeem raug suav hais tias yog: khoom → khoom. Nws zoo ib yam li kneading mov paj, qhov twg lwm lub zog siv los kho cov khoom hauv qhov tuag.
· Casting tsom rua kev tswj cov hlau melting thiab pouring txheej txheem.
· Forging yog ib daim ntawv ntawm cov khoom siv- lub xeev cov yas tsim thiab tuaj yeem muab faib ua kub forging thiab txias forging, nrog rau cov txheej txheem tshwj xeeb xws li extrusion, kos duab, chim siab, thiab xuas nrig ntaus.
(2) Txoj Kev Tsim thiab Microstructural Properties:
Casting yog ib qho - cov txheej txheem tsim nyog rau qhov chaw uas muaj cov duab nyuaj lossis kab noj hniav, tab sis nws yuav ua rau muaj qhov tsis xws luag xws li porosity thiab shrinkage vim qhov txias txias.
Forging yog cov txheej txheem kev txhim kho uas feem ntau cuam tshuam nrog ntau theem ntawm deformation; nws refines cov hlau cov qauv nplej thiab compacts lub microstructure, yog li pab txhawb ib feem lub zog thiab toughness.
II. Qhov txawv ntawm Qhib Tuag Forging thiab Tuag Forging
Qhib- tuag forging koom nrog muab cov hlau nplaum uas muaj cua sov ntawm cov tuag sab saud thiab qis thiab deforming nws los ntawm kev cuam tshuam los yog siab kom maj mam ua tiav cov duab xav tau. Nws yog qhov tsim nyog rau kev tsim cov forgings nrog cov duab yooj yim, nrog rau ib qho - thooj, me -batch, lossis loj, hnyav - lub luag haujlwm forgings.
· Phau ntawv qhib- tuag forging: Kev ua haujlwm- siv zog thiab ua haujlwm qis, feem ntau yog siv los kho cov haujlwm lossis cov khoom me me. · Tshuab qhib- tuag forging: Thawj txoj hauv kev niaj hnub tsim khoom, ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuab hnyav.
Tuag forging yuav shaping rhuab billets nyob rau hauv cov kab noj hniav ntawm tuag mounted rau forging khoom.
· Cov cuab yeej siv feem ntau suav nrog chav - cua rauj (feem ntau ntawm 0.5 txog 30 tons) thiab kub tuag forging presses (feem ntau yog li ntawm 25,000 txog 63,000 kN).
· Kev tuag tuaj yeem muab faib ua ib qho -kab noj hniav thiab ntau- kab noj hniav. Cov txheej txheem feem ntau muab cov kev npaj billet thiab kev ua haujlwm forging zaum kawg, nrog rau cov kauj ruam kawg ntawm kev tshem tawm flash kom tau qhov tiav forging.
