Forging yog hais txog kev tsim thiab ua cov txheej txheem ntawm kev siv lub zog sab nraud rau cov hlau blanks (tsis suav cov phaj) los tsim cov yas deformation, hloov loj, thiab cov duab thiab txhim kho kev ua tau zoo, uas yog siv los tsim cov khoom siv kho tshuab, cov khoom ua haujlwm, cov cuab yeej, lossis cov khoom seem.
Thaum qhov kub siab tshaj 300-400 degree (xiav cheeb tsam ntawm cov hlau) thiab nce mus txog 700-800 degree, lub deformation kuj yuav txo qis thiab lub zog deformation yuav zoo heev.
Lub forging nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, raws li qhov sib txawv forging zoo thiab forging txheej txheem yuav tsum tau muab faib ua peb qhov chaw kub: txias forging, sov forging, thiab kub forging. Keeb kwm, tsis muaj ciam teb nruj rau kev faib cov cheeb tsam kub no. Feem ntau hais lus, forging nyob rau hauv cheeb tsam kub nrog recrystallization yog hu ua kub forging, thiab forging tsis muaj cua sov ntawm chav tsev kub yog hu ua txias forging.
Thaum forging ntawm qhov kub qis, qhov hloov pauv loj ntawm forgings me me heev. Forging qis dua 700 degree, qhov tsim ntawm oxide nplai tsawg dua, thiab tsis muaj decarburization ntawm qhov chaw. Yog li ntawd, ntev npaum li qhov deformation tuaj yeem nyob hauv thaj tsam ntawm kev tsim lub zog, txias forging yog ib qho yooj yim kom tau txais qhov zoo ntawm qhov tseeb thiab qhov chaw tiav. Ntev npaum li qhov ntsuas kub thiab lubrication txias tswj tau zoo, sov forging hauv qab 700 degree kuj tuaj yeem tau txais qhov raug zoo.
Thaum lub sij hawm kub forging, loj forgings nrog complex duab yuav forged vim hais tias lub zog deformation thiab deformation kuj yog tsawg heev. Txhawm rau kom tau txais forgings nrog qhov tseeb qhov tseeb, kub forging tuaj yeem siv rau qhov kub thiab txias ntawm 900-1000 degree . Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau kev txhim kho qhov chaw ua haujlwm ntawm kub forging. Lub neej kev pab cuam ntawm forging tuag (kub forging 2000-5000, sov forging 10000-20000, txias forging 20000-50000) yog luv dua li ntawm forging nyob rau hauv lwm yam kub kub, tab sis nws muaj loj degree ntawm kev ywj pheej thiab tus nqi qis.
Qhov khoob yuav deformed thiab ua hauj lwm-hardened thaum lub sij hawm txias forging kom lub forging tuag yuav ris lub siab load. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv lub zog siab forging tuag thiab txais yuav txoj kev kho mob ntawm lub zog lubricating zaj duab xis kom tsis txhob hnav thiab adhesion. Tsis tas li ntawd, txhawm rau tiv thaiv cov kab nrib pleb, qhov nruab nrab annealing yog nqa tawm thaum tsim nyog los xyuas kom meej qhov yuav tsum tau muaj peev xwm deformation. Yuav kom tswj tau cov lubrication zoo, qhov khoob tuaj yeem ua phosphate. Thaum kev ua haujlwm tas mus li yog nqa nrog cov tuav thiab cov hlua hlau, ntu tsis tuaj yeem lubricated tam sim no, thiab muaj peev xwm ntawm kev siv phosphating lubrication txoj kev raug kawm.
Raws li txoj kev txav ntawm qhov khoob, forging tuaj yeem muab faib ua dawb forging, chim siab, extrusion, tuag forging, kaw tuag forging, thiab kaw chim siab. Vim tias tsis muaj flash nyob rau hauv kaw tuag forging thiab kaw chim siab, qhov kev siv ntawm cov ntaub ntawv yog siab. Nws muaj peev xwm ua kom tiav machining complex forgings nrog ib lossis ob peb txheej txheem. Vim tias tsis muaj flash, qhov kev ntxhov siab ntawm forgings raug txo, thiab cov load yuav tsum tau txo. Txawm li cas los xij, nws yuav tsum raug sau tseg tias qhov khoob yuav tsum tsis txhob txwv tag nrho. Yog li ntawd, qhov ntim ntawm qhov khoob yuav tsum tau tswj nruj me ntsis, qhov chaw txheeb ze ntawm forging tuag yuav tsum tau tswj, thiab cov forgings yuav tsum tau ntsuas los sim txo qhov hnav ntawm forging tuag.
