Forging yog lub npe sib sau ua ke rau forging thiab stamping.Nws yog ib txoj hauv kev tsim cov txheej txheem uas siv rauj, anvil, thiab xuas nrig ntaus ntawm lub tshuab forging lossis pwm los ua kom lub siab ntawm qhov khoob kom ua rau cov yas deformation kom tau txais cov khoom ntawm cov duab thiab qhov loj me.
Dab tsi yog forging
Thaum lub sij hawm forging txheej txheem, tag nrho cov dawb paug undergoes tseem ceeb yas deformation thiab ib tug kuj loj npaum li cas ntawm cov yas ntws.Nyob rau hauv cov txheej txheem stamping, qhov dawb paug feem ntau yog tsim los ntawm kev hloov qhov chaw ntawm txhua qhov chaw, thiab tsis muaj cov yas ntws los ntawm qhov deb loj hauv nws.Forging feem ntau yog siv los ua cov khoom hlau.Nws kuj tseem tuaj yeem siv los ua cov hlau tsis yog hlau, xws li engineering plastics, roj hmab, ceramic blanks, cib, thiab kev tsim cov khoom sib xyaw.
Rolling, kos duab, thiab lwm yam nyob rau hauv forging thiab metallurgical industries yog tag nrho cov yas los yog siab ua.Txawm li cas los xij, forging feem ntau yog siv los tsim cov khoom hlau, thaum dov thiab kos duab yog siv los tsim cov khoom siv hlau dav dav xws li daim hlau, strips, kav, profiles, thiab cov xov hlau.
Classification ntawm Forging
Forging feem ntau yog cais raws li txoj kev tsim thiab deformation kub.Raws li txoj kev tsim, forging tuaj yeem muab faib ua ob pawg: forging thiab stamping.Raws li qhov kub deformation, forging tuaj yeem muab faib ua kub forging, txias forging, sov forging, thiab isothermal forging, thiab lwm yam.
1. Kub forging
Kub forging yog forging ua saum toj no lub recrystallization kub ntawm cov hlau.Ua kom qhov kub thiab txias tuaj yeem txhim kho cov yas ntawm cov hlau, uas yog qhov zoo rau kev txhim kho qhov zoo ntawm cov khoom ua haujlwm thiab ua rau nws tsis tshua muaj kev tawg.Cov kub kub kuj tseem tuaj yeem txo qhov deformation tsis kam ntawm cov hlau thiab txo cov tonnage ntawm qhov xav tauforging tshuab.Txawm li cas los xij, muaj ntau cov txheej txheem kub forging, lub workpiece precision tsis zoo, thiab nto tsis du.Thiab cov forgings yog nquag oxidation, decarburization, thiab hlawv puas.Thaum lub workpiece loj thiab tuab, cov khoom muaj lub zog siab thiab tsis tshua muaj plasticity (xws li yob dabtsi yog khoov ntawm daim hlau ntxiv, kos duab ntawm cov pa roj carbon steel rods, thiab lwm yam), thiab kub forging yog siv.
Feem ntau siv kub forging kub yog: carbon steel 800 ~ 1250 ℃;alloy yam ntxwv steel 850 ~ 1150 ℃;kev kub ceev steel 900 ~ 1100 ℃;feem ntau siv aluminium alloy 380 ~ 500 ℃;alloy 850 ~ 1000 ℃;tooj dag 700 ~ 900 ℃.
2. Txias forging
Txias forging yog forging ua hauv qab cov hlau recrystallization kub.Feem ntau hais lus, txias forging yog hais txog forging ntawm chav tsev kub.
Cov workpieces tsim los ntawm txias forging ntawm chav tsev kub muaj cov duab siab thiab qhov tseeb, qhov chaw du, ob peb kauj ruam ua haujlwm, thiab yooj yim rau kev tsim khoom.Ntau qhov txias forged thiab txias stamped qhov chaw tuaj yeem siv ncaj qha los ua cov khoom lossis cov khoom tsis tas yuav tsum tau ua haujlwm.Txawm li cas los xij, thaum lub sij hawm txias forging, vim cov yas tsis tshua muaj hlau, tawg yooj yim tshwm sim thaum lub sij hawm deformation thiab deformation kuj yog loj, yuav tsum tau loj-tonnage forging machinery.
3. Kub forging
Forging ntawm qhov kub siab tshaj qhov kub ib txwm tab sis tsis tshaj qhov kub ntawm recrystallization yog hu ua sov forging.Cov hlau yog preheated, thiab cov cua kub kub yog qis dua qhov kub forging.Qhov sov forging muaj ntau dua precision, ib tug smoother nto, thiab tsawg deformation kuj.
4. Isothermal forging
Isothermal forging ua kom qhov kub thiab txias tsis tu ncua thaum lub sijhawm ua tiav tag nrho.Isothermal forging yog ua kom siv tag nrho cov yas siab ntawm qee cov hlau ntawm tib qhov kub los yog kom tau txais cov qauv tshwj xeeb thiab cov khoom.Isothermal forging yuav tsum khaws cov pwm thiab cov khoom tsis zoo ntawm qhov kub thiab txias, uas yuav tsum tau muaj cov nqi siab thiab tsuas yog siv rau cov txheej txheem forging tshwj xeeb, xws li superplastic forming.
Cov yam ntxwv ntawm Forging
Forging tuaj yeem hloov cov qauv hlau thiab txhim kho cov khoom hlau.Tom qab lub ingot yog kub forged, tus thawj looseness, pores, micro-cracks, thiab lwm yam nyob rau hauv lub cam khwb cia lub xeev yog compacted los yog welded.Thawj dendrites tawg, ua rau cov nplej zoo dua.Nyob rau tib lub sijhawm, kev sib cais ntawm cov carbide qub thiab kev faib tsis sib xws tau hloov pauv.Ua kom cov qauv sib txawv, kom tau txais kev zam txim uas tau hnov qab, hnav ris tsho, muaj qhov ua tau zoo, thiab muaj kev ntseeg siab tag nrho hauv kev siv.Tom qab forging yog deformed los ntawm kub forging, cov hlau muaj ib tug fibrous qauv.Tom qab txias forging deformation, cov hlau siv lead ua ua kom zoo.
Forging yog ua kom cov hlau ntws plastically los ua ib qho haujlwm ntawm qhov xav tau.Lub ntim ntawm cov hlau tsis hloov tom qab cov yas ntws tau tshwm sim vim yog sab nraud quab yuam, thiab cov hlau ib txwm ntws mus rau qhov uas tsis muaj zog tshaj plaws.Hauv kev tsim khoom, cov duab ntawm lub workpiece feem ntau yog tswj raws li cov cai no kom ua tiav cov deformations xws li thickening, elongation, expansion, dabtsi yog khoov, thiab sib sib zog nqus daim duab.
Qhov loj ntawm forged workpiece yog qhov tseeb thiab yog qhov tsim nyog rau kev tsim khoom loj.Qhov ntev ntawm pwm tsim hauv daim ntawv thov xws li forging, extrusion, thiab stamping yog qhov tseeb thiab ruaj khov.High-efficiency forging machinery thiab tsis siv neeg forging ntau lawm kab tuaj yeem siv los npaj cov khoom tshwj xeeb lossis ntau lawm.
Feem ntau siv forging machinery suav nrog forging rauj,hydraulic presses, thiab mechanical presses.Lub forging rauj muaj qhov cuam tshuam loj, uas yog qhov zoo rau cov yas ntws ntawm cov hlau, tab sis nws yuav tsim kev co.Cov xovxwm hydraulic siv static forging, uas yog qhov zoo rau forging los ntawm cov hlau thiab txhim kho cov qauv.Kev ua haujlwm ruaj khov, tab sis cov khoom tsim tau qis.Mechanical xovxwm muaj qhov ruaj khov stroke thiab yooj yim rau kev siv tshuab thiab automation.
Txoj kev loj hlob ntawm Forging Technology
1) Txhawm rau txhim kho qhov zoo ntawm cov khoom forged, feem ntau los txhim kho lawv cov khoom siv kho tshuab (lub zog, plasticity, toughness, qaug zog) thiab kev ntseeg tau.
Qhov no yuav tsum muaj kev siv zoo dua ntawm txoj kev xav ntawm cov yas deformation ntawm cov hlau.Siv cov ntaub ntawv uas muaj qhov zoo dua qub, xws li lub tshuab nqus tsev kho mob thiab lub tshuab nqus tsev-melted steel.Ua ntej-forging cua sov thiab forging cua sov kho kom raug.Kev nruj dua thiab dav tsis muaj kev puas tsuaj ntawm cov khoom forged.
2) Txuas ntxiv txhim kho precision forging thiab precision stamping tshuab.Kev txiav tsis siv neeg txiav yog qhov tseem ceeb tshaj plaws kev ntsuas thiab kev taw qhia rau kev lag luam machinery los txhim kho kev siv cov khoom siv, txhim kho kev ua haujlwm ntawm kev ua haujlwm, thiab txo kev siv hluav taws xob.Txoj kev loj hlob ntawm non-oxidative cua sov ntawm forging blanks, raws li zoo raws li high-hardness, hnav-resistant, ntev-lub neej pwm cov ntaub ntawv thiab cov txheej txheem kev kho mob saum npoo, yuav ua tau rau cov ntaub ntawv nthuav dav ntawm precision forging thiab precision stamping.
3) Tsim cov cuab yeej forging thiab forging cov kab ntau lawm nrog kev tsim khoom ntau dua thiab automation.Raws li kev tsim tshwj xeeb, kev tsim khoom tsim tau zoo heev thiab cov nqi forging raug txo.
4) Txhim kho cov txheej txheem forging hloov tau yooj yim (siv pab pawg thev naus laus zis, hloov pauv sai, thiab lwm yam).Qhov no ua rau muaj ntau yam, me me-batch forging ntau lawm los siv high-efficiency thiab siab automated forging khoom los yog ntau lawm kab.Ua kom nws cov khoom tsim tau thiab kev lag luam ze rau qib ntawm kev tsim khoom loj.
5) Tsim cov ntaub ntawv tshiab, xws li forging txheej txheem ntawm cov hmoov metallurgy cov ntaub ntawv (tshwj xeeb tshaj yog ob-txheej hlau hmoov), kua hlau, fiber-reinforced plastics, thiab lwm yam ntaub ntawv sib xyaw.Tsim cov technologies xws li superplastic forming, high-energy forming, thiab internal high-pressure forming.
