Sheet hlau stamping yog txheej txheem tsim uas siv cov xovxwm thiab tuag ua cov cuab yeej tseem ceeb. Nws siv lub zog sab nraud rau cov ntawv hlau, ua rau cov yas deformation los yog sib cais kom tau txais qhov chaw ntawm qhov xav tau thiab qhov loj me. Raws li ib qho kev ua tau zoo thiab kev lag luam loj hauv kev ua haujlwm hlau, nws txoj hauv kev yog ua raws li kev sib koom ua ke ntawm cov khoom siv plasticity mechanics, kev txwv tuag, thiab cov khoom siv zog. Nws yog dav siv nyob rau hauv ntau yam industrial manufacturing scenarios xws li tsheb, khoom siv hauv tsev, electronics, thiab kev tsim kho.
Qhov tseem ceeb, cov ntawv hlau stamping txheej txheem cuam tshuam nrog kev ntxhov siab ntawm cov ntawv hlau ntau tshaj nws lub zog tawm los ntawm sab nraud quab yuam, nkag mus rau cov yas deformation theem, yog li ua tiav qhov kev hloov pauv ntawm cov duab thiab qhov loj me. Cov xovxwm muab qhov xav tau stamping quab yuam, uas, los ntawm kev xuas nrig ntaus thiab tuag ntawm qhov tuag, siv cov concentrated lossis faib cov khoom rau cov ntawv hlau, ua rau nws ntws los yog sib cais raws txoj hauv kev uas tau txiav txim siab nyob rau hauv qhov txwv ntawm qhov tuag kab noj hniav. Raws li cov khoom tsim, cov txheej txheem stamping tuaj yeem muab faib ua ob pawg loj: cov txheej txheem sib cais thiab cov txheej txheem tsim. Txoj kev sib cais muaj xws li blanking, xuas nrig ntaus, thiab trimming, aiming rau shear ib feem ntawm daim ntawv hlau raws li ib tug kaw contour, cais nws los ntawm lub hauv paus khoom. Cov txheej txheem tsim encompasses dabtsi yog khoov, sib sib zog nqus kos duab, flanging, thiab bulging, tso cai rau cov khoom kom ua tau raws li peb xav tau - qhov ntev contour thiab lub zos duab yam tsis muaj kev tawg.
Nyob rau hauv txoj kev sib cais, cov npoo tuag yog haum nrog ib qho kev tshem tawm. Thaum cov punch txav mus rau hauv qab, nws siv lub zog shearing rau cov ntawv hlau, ua rau cov kab nrib pleb tsim thiab nthuav tawm raws cov kab txiav ntug, thaum kawg sib cais cov khoom. Qhov luaj li cas, txiav ntug sharpness, thiab xuas nrig ntaus ceev ncaj qha cuam tshuam rau tus ntoo khaub lig-sectional zoo thiab seem raug. Cov txheej txheem tsim nyob rau ntawm cov yas ntws ntawm cov khoom nyob rau hauv kev sib xyaw ua ke ntawm compressive thiab tensile stresses. Piv txwv li, thaum lub sij hawm sib sib zog nqus nqus, cov xuas nrig ntaus cov ntawv hlau rau hauv qhov tuag, thiab cov khoom siv radial elongation thiab thickness txo nyob rau hauv qhov kev txwv ntawm lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Bending yuam cov ntawv hlau hloov lub kaum sab xis nyob ib ncig ntawm ib qho axis los ntawm kev xuas nrig ntaus thiab tuag, nrog rau kev ncab thiab compression ntawm cov fibers sab hauv thiab sab nrauv, uas ua rau muaj qhov deformation mus tas li.
Lub formability ntawm cov khoom yog ib tug tseem ceeb yam tseem ceeb txiav txim lub feasibility ntawm stamping. Lub zog tawm los, elongation, hardening Performance index, thiab thickness anisotropy coefficient ntawm txawv hlau los xij ncaj qha cuam tshuam rau lawv nyiam tawg, wrinkle, thiab springback. Kev xaiv cov khoom tsim nyog thiab cov txheej txheem sib txuam tuaj yeem txo cov khoom tuag thiab cov khoom seem thaum ua kom zoo. Lub tshuab roj lubrication kuj tseem ua lub luag haujlwm tseem ceeb hauv cov txheej txheem stamping; los ntawm kev tsim cov roj zaj duab xis rau saum npoo ntawm cov ntawv hlau thiab tuag, nws txo cov kev sib txhuam tsis zoo thiab cov cua sov sib xyaw, txhim kho cov khoom ntws thiab txuas lub neej ntev.
Cov yam ntxwv ntawm lub zog ntawm cov xovxwm thiab qhov tseeb geometric ntawm cov tuag ua ke kom ruaj khov kev siv ntawm cov txheej txheem stamping. Mechanical presses cia siab rau flywheel zog cia thiab clutch braking kom ua tau reciprocating tsab ntawv tsa suab, thaum hydraulic presses siv cov kua siab los tsav tus swb, muab loj thiab tswj tsis pub muaj zog tuav, haum rau hnyav - lub luag hauj lwm tej yam kev mob xws li sib sib zog nqus nqus. Cov kev taw qhia raug, clearance uniformity, thiab nto roughness ntawm cov tuag txiav txim siab qhov ua tau zoo ntawm kev tsim quab yuam kis tau tus mob thiab qhov seem sib xws ntawm qhov chaw.
Niaj hnub nimno ntawv hlau stamping tseem suav nrog cov kev simulation digital thiab kev soj ntsuam online. Kev txheeb xyuas cov ntsiab lus kawg tuaj yeem kwv yees kev ntxhov siab- lim kev faib tawm thiab tsim cov teeb meem thaum lub sijhawm tsim txheej txheem, txhim kho cov txheej txheem tsis zoo. Lub tonnage thiab tshem tawm xyuas qhov nruab rau ntawm cov xovxwm tuaj yeem ntes cov kev hloov pauv txawv txav thaum lub sijhawm tsim cov txheej txheem ntawm lub sijhawm tiag tiag, muab lub hauv paus rau kev tswj kom zoo thiab kho cov cuab yeej siv.
Feem ntau, lub hauv paus ntsiab lus ntawm cov ntawv hlau stamping yog ua raws li plasticity mechanics. Los ntawm lub hwj chim muab los ntawm cov xovxwm thiab kev txwv thiab kev taw qhia siv los ntawm kev tuag, cov ntawv hlau yog sib cais los yog tsim nyob rau hauv cov xwm txheej tswj tau. Kev nkag siab tob thiab meej ntawm cov ntsiab lus no yog qhov tseem ceeb ua ntej kom ua tiav qib siab - zoo, siab - stamping efficiency, thiab tseem nteg lub hauv paus ruaj khov theoretical rau cov txheej txheem kev tsim kho tshiab thiab kev hloov kho khoom siv.
