1. Forging: Nws yog ib txoj hauv kev uas siv cov tshuab forging los siv lub siab rau cov hlau blanks los tsim cov yas deformation kom tau txais forgings nrog qee yam khoom siv, qee yam duab thiab ntau thiab tsawg.
2. Ib qho ntawm ob qhov tseem ceeb ntawm forging.Los ntawm forging, cov hlau thiab vuam qhov tuaj yeem raug tshem tawm, thiab cov cuab yeej cuab tam ntawm forgings feem ntau zoo dua li cov castings ntawm tib cov khoom.Rau qhov tseem ceeb ntawm cov tshuab uas muaj kev thauj khoom hnyav thiab kev ua haujlwm hnyav, forgings feem ntau yog siv tshwj tsis yog cov duab yooj yim uas tuaj yeem dov, profiles lossis welded qhov chaw.
3. Raws li txoj kev tsim, forging tuaj yeem muab faib ua: ①Open forging (free forging).Siv cov kev cuam tshuam los yog siab kom deform cov hlau nruab nrab ntawm sab sauv thiab qis anvils (anvils) kom tau qhov yuav tsum tau forgings.Muaj feem ntau yog phau ntawv forging thiab mechanical forging.② Kaw hom forging.Cov hlau dawb paug yog compressed thiab deformed nyob rau hauv ib tug forging tuag nrog ib tug tej yam zoo li kom tau forgings, uas yuav muab faib ua tuag forging, txias-rhiab, rotary forging, thiab extrusion.Raws li qhov kub ntawm deformation, forging tuaj yeem muab faib ua kub forging (kev ua haujlwm kub siab dua li qhov kub ntawm cov hlau tsis muaj recrystallization), sov forging (hauv qab qhov kub ntawm recrystallization) thiab txias forging (ib txwm kub).
4. Forging cov ntaub ntawv feem ntau yog carbon steel thiab alloy steel nrog ntau yam compositions, ua raws li txhuas, magnesium, titanium, tooj liab, thiab lwm yam thiab lawv alloys.Thawj lub xeev ntawm cov khoom muaj xws li bar Tshuag, cam khwb cia saw, hlau hmoov thiab kua hlau.Qhov sib piv ntawm qhov chaw hla ntawm cov hlau ua ntej deformation mus rau qhov chaw seem tuag tom qab deformation yog hu ua forging ratio.Kev xaiv kom raug ntawm forging ratios muaj ntau yam ua rau kev txhim kho cov khoom zoo thiab txo cov nqi.
