Forging tuaj yeem raug cais raws li cov hauv qab no:
1. Muab faib raws li qhov chaw ntawm cov cuab yeej forging thiab pwm.
2. Muab faib los ntawm forging forming kub.
3. Muab faib raws li hom kev sib txheeb ntawm cov cuab yeej forging thiab workpieces.
Kev npaj ua ntej forging suav nrog kev xaiv raw khoom, suav cov khoom siv, txiav, cua sov, suav deformation quab yuam, xaiv cov khoom siv, thiab tsim pwm. Ua ntej forging, nws yog ib qhov tsim nyog los xaiv ib tug zoo lubrication txoj kev thiab lubricant.
Forging cov ntaub ntawv npog ntau yam, suav nrog ntau qib ntawm cov hlau thiab cov hlau kub kub, nrog rau cov hlau tsis muaj hlau xws li txhuas, magnesium, thiab tooj liab; Muaj ob qho tib si rods thiab profiles ntawm ntau qhov sib txawv ua tiav ib zaug, nrog rau cov ingots ntawm ntau yam specifications; Ntxiv nrog rau kev siv cov khoom siv hauv tsev tsim nyog rau peb lub teb chaws cov peev txheej, kuj muaj cov khoom siv los ntawm txawv teb chaws. Feem ntau ntawm cov ntaub ntawv forged twb tau teev nyob rau hauv lub teb chaws tus qauv. Kuj tseem muaj ntau yam khoom tshiab uas tau tsim, sim, thiab txhawb nqa. Raws li paub zoo, qhov zoo ntawm cov khoom feem ntau yog ze ze rau qhov zoo ntawm cov khoom siv raw. Yog li ntawd, cov neeg ua haujlwm forging yuav tsum muaj kev paub ntau thiab tob ntawm cov ntaub ntawv thiab ua tib zoo xaiv cov khoom tsim nyog raws li cov txheej txheem yuav tsum tau ua.
Kev suav cov khoom siv thiab txiav yog cov kauj ruam tseem ceeb hauv kev txhim kho kev siv cov khoom siv thiab ua kom tiav cov khoom seem. Cov khoom siv ntau dhau tsis tsuas yog ua rau cov khoom pov tseg, tab sis kuj ua rau pwm hnyav thiab siv zog. Yog tias tsis muaj cov npoo me ntsis sab laug thaum txiav, nws yuav ua rau qhov nyuaj ntawm kev hloov kho thiab ua kom cov seem seem. Tsis tas li ntawd, qhov zoo ntawm qhov kawg ntawm lub ntsej muag kuj muaj kev cuam tshuam rau cov txheej txheem thiab forging zoo.
Lub hom phiaj ntawm cov cua sov yog txo forging deformation quab yuam thiab txhim kho hlau plasticity. Tab sis cua sov kuj coj cov teeb meem, xws li oxidation, decarburization, overheating, thiab overburning. Kev tswj xyuas qhov kub thiab txias ntawm qhov kawg forging muaj qhov cuam tshuam loj rau microstructure thiab cov khoom ntawm cov khoom. Cov nplaim hluav taws kub cua sov muaj qhov zoo ntawm tus nqi qis thiab muaj zog yoog raws, tab sis lub sijhawm cua sov yog ntev, uas ua rau oxidation thiab decarburization, thiab cov kev ua haujlwm tseem yuav tsum tau txhim kho tas li. Induction cua sov muaj qhov zoo ntawm cov cua kub ceev thiab tsawg oxidation, tab sis nws cov kev hloov pauv rau cov khoom zoo, qhov loj me, thiab cov khoom siv tsis zoo. Kev siv lub zog ntawm cov txheej txheem cua sov ua lub luag haujlwm tseem ceeb hauv kev siv lub zog ntawm forging ntau lawm thiab yuav tsum muaj nuj nqis tag nrho.
Forging yog tsim nyob rau hauv sab nraud quab yuam. Yog li ntawd, kev xam qhov tseeb ntawm deformation quab yuam yog lub hauv paus rau kev xaiv cov khoom siv thiab ua cov pwm pov thawj. Kev soj ntsuam kev ntxhov siab hauv lub cev deformed kuj tseem yog qhov tseem ceeb rau kev txhim kho cov txheej txheem thiab tswj cov microstructure thiab cov khoom ntawm forgings. Muaj plaub txoj hauv kev tseem ceeb rau kev tshuaj xyuas deformation quab yuam. Txawm hais tias tus thawj coj kev ntxhov siab tsis yog nruj heev, nws yog qhov yooj yim thiab intuitive. Nws tuaj yeem xam tag nrho cov siab thiab kev ntxhov siab faib rau ntawm qhov chaw sib chwv ntawm qhov chaw ua haujlwm thiab cov cuab yeej, thiab tuaj yeem pom qhov cuam tshuam ntawm qhov sib piv thiab kev sib txhuam coefficient ntawm lub workpiece ntawm nws; Txoj kev swb txoj kab yog nruj rau cov teeb meem dav hlau thiab muab cov kev daws teeb meem ntau dua rau kev ntxhov siab hauv zos deformation ntawm workpieces. Txawm li cas los xij, nws qhov kev siv tau yog nqaim thiab tsis tshua muaj qhia hauv cov ntaub ntawv tsis ntev los no; Cov txheej txheem sab saud tuaj yeem muab cov khoom hnyav tshaj plaws, tab sis los ntawm kev xav txog kev kawm, nws tsis nruj heev thiab tuaj yeem muab cov ntaub ntawv tsawg dua li cov txheej txheem finite, yog li nws tsis tshua muaj siv tsis ntev los no; Cov txheej txheem finite element tuaj yeem tsis tsuas yog muab cov khoom siv sab nraud thiab cov kev hloov pauv hauv cov duab ntawm lub workpiece, tab sis kuj muab cov kev ntxhov siab sab hauv kev faib tawm thiab kwv yees cov teeb meem uas tuaj yeem ua tau, ua rau nws txoj kev ua haujlwm zoo heev. Nyob rau hauv ob peb xyoos dhau los, vim lub sij hawm ntev kev xam yuav tsum tau thiab xav tau kev txhim kho nyob rau hauv technical teeb meem xws li daim phiaj redrawing, daim ntawv thov scope twb txwv rau cov tsev kawm ntawv qib siab thiab cov tsev kawm tshawb fawb. Nyob rau hauv xyoo tas los no, nrog rau qhov muaj koob meej thiab kev txhim kho sai ntawm cov khoos phis tawj, nrog rau kev ua lag luam zoo zuj zus software rau kev txheeb xyuas cov ntsiab lus, cov qauv no tau dhau los ua cov cuab yeej siv tshuaj ntsuam xyuas thiab suav.
Txo kev sib txhuam tsis tau tsuas yog txuag lub zog, tab sis kuj txhim kho lub neej ntawm pwm. Ib qho ntawm cov kev ntsuas tseem ceeb los txo kev sib txhuam yog siv lubrication, uas pab txhim kho microstructure thiab cov khoom ntawm cov khoom vim nws cov yam ntxwv deformation. Vim yog txoj kev sib txawv forging thiab ua haujlwm kub, cov roj nplua nyeem siv kuj sib txawv. Cov iav lubricants feem ntau yog siv rau forging high-temperature alloys thiab titanium alloys. Rau kub forging ntawm steel, dej-raws li graphite yog ib tug dav siv lubricant. Rau qhov txias forging, vim kev kub siab, kev kho phosphate lossis oxalate feem ntau yuav tsum tau ua ntej forging.
