1. Kub Stamping vs Cold Stamping
Kub stamping yog txheej txheem tsim uas tau ua tom qab preheating cov ntawv hlau, thaum txias stamping yog hais txog qhov ncaj qha stamping ntawm cov ntawv hlau tsis muaj preheating.
Txias stamping muaj qhov zoo tshaj qhov kub stamping.Txawm li cas los xij, nws kuj muaj qee qhov tsis zoo.Vim tias muaj kev ntxhov siab ntau dua los ntawm cov txheej txheem txias stamping piv rau kub stamping, cov khoom txias-stamped muaj qhov cuam tshuam rau kev tawg thiab tawg.Yog li ntawd, cov khoom siv stamping yog qhov yuav tsum tau ua rau txias stamping.
Kub stamping muaj cua sov cov ntawv hlau kom kub siab ua ntej stamping thiab ib txhij quenching hauv qhov tuag.Qhov no ua rau kom muaj kev hloov pauv ntawm cov hlau lub microstructure mus rau hauv martensite, uas ua rau lub zog siab ntawm 1500 txog 2000 MPa.Yog li ntawd, cov khoom kub-stamped muaj zog dua piv rau cov khoom txias-stamped counterparts.
2. Kub Stamping txheej txheem ntws
Kub stamping, tseem hu ua "xovxwm hardening," suav nrog cua sov cov ntawv muaj zog nrog lub zog pib ntawm 500-600 MPa rau qhov kub ntawm 880 thiab 950 ° C.Cov ntawv rhuab yog tam sim ntawd stamped thiab quenched nyob rau hauv qhov tuag, ua tiav cov cua txias ntawm 20-300 ° C / s.Kev hloov pauv ntawm austenite mus rau hauv martensite thaum lub sij hawm quenching ho txhim kho lub zog ntawm cov khoom tivthaiv, tso cai rau kev tsim cov khoom stamped nrog lub zog txog li 1500 MPa.Hot stamping cov txheej txheem tuaj yeem faib ua ob pawg: ncaj qha kub stamping thiab indirect kub stamping:
Nyob rau hauv qhov ncaj kub stamping, lub preheated dawb paug yog ncaj qha mus rau hauv lub kaw tuag rau stamping thiab quenching.Cov txheej txheem tom qab muaj xws li cua txias, ntug trimming thiab lub qhov xuas nrig ntaus (los yog laser txiav), thiab ntxuav saum npoo.
Fiture1: kub stamping ua hom - ncaj qha kub stamping
Nyob rau hauv cov txheej txheem kub kub stamping, qhov txias ua ntej-shaping kauj ruam yog ua ua ntej nkag mus rau cov theem ntawm cov cua sov, kub stamping, ntug trimming, qhov punching, thiab deg tu.
Lub ntsiab sib txawv ntawm indirect kub stamping thiab ncaj qha kub stamping txheej txheem yog nyob rau hauv lub inclusion ntawm txias forming pre-shaping kauj ruam ua ntej cua sov nyob rau hauv txoj kev indirect.Nyob rau hauv ncaj qha kub stamping, cov ntawv hlau yog ncaj qha mus rau hauv lub qhov cub cua sov, thaum nyob rau hauv indirect kub stamping, lub txias-tsim pre-zoo li tus tivthaiv yog xa mus rau hauv lub cua sov rauv.
Cov txheej txheem ntws ntawm indirect kub stamping feem ntau suav nrog cov kauj ruam hauv qab no:
Txias txoj kev ua ntej-shaping-- Cua sov- Kub stamping-- Ntug trimming thiab qhov xuas nrig ntaus-Ntog tu

3.Cov cuab yeej tseem ceeb rau kub stamping muaj xws li lub qhov cub cua sov, kub sib sau xovxwm, thiab kub stamping pwm
Cua sov rauv:
Lub qhov cub cua sov yog nruab nrog cov cua sov thiab tswj qhov kub thiab txias.Nws muaj peev xwm ua kom sov cov phaj siab zog rau qhov ntsuas kub ntawm recrystallization nyob rau hauv ib lub sij hawm teev, ua tiav lub xeev austenitic.Nws yuav tsum tau hloov mus rau qhov loj-scale automated nruam ntau lawm yuav tsum tau.Raws li cov rhuab billet tsuas yog siv tau los ntawm cov neeg hlau lossis cov cuab yeej cuab tam, lub tshuab hluav taws xob yuav tsum tau siv lub tshuab thauj khoom thiab tshem tawm nrog qhov tseeb qhov chaw siab.Tsis tas li ntawd, thaum tshav kub tsis-coated steel daim hlau, nws yuav tsum muab kev tiv thaiv roj los tiv thaiv oxidation nto thiab decarbonization ntawm billet.
Kub Forming Xovxwm:
Cov xovxwm yog qhov tseem ceeb ntawm cov tshuab kub stamping.Nws yuav tsum muaj peev xwm ua kom nrawm nrawm thiab tuav, nrog rau yuav tsum tau nruab nrog lub tshuab cua txias ceev.Cov txheej txheem complexity ntawm kub forming presses deb tshaj li cov pa txias stamping presses.Tam sim no, tsuas yog ob peb lub tuam txhab txawv teb chaws tau paub txog kev tsim thiab tsim tshuab ntawm cov xovxwm, thiab lawv txhua tus nyob ntawm kev xa khoom, ua rau lawv kim.
Kub Stamping Moulds:
Kub stamping pwm ua ob qho tib si tsim thiab quenching theem.Nyob rau hauv txoj kev tsim, ib zaug lub billet yog pub rau hauv pwm kab noj hniav, cov pwm sai sai ua tiav cov txheej txheem stamping kom paub tseeb tias qhov ua tiav ntawm ib feem tsim ua ntej cov khoom undergoes lub martensitic theem transformation.Tom qab ntawd, nws nkag mus rau theem quenching thiab txias, qhov twg cov cua sov ntawm lub workpiece hauv pwm yog txuas mus rau pwm.Cov kav dej txias tau npaj rau hauv pwm tam sim tshem tawm cov cua sov los ntawm cov dej txias ntws.Martensitic-austenitic transformation pib thaum lub workpiece kub poob mus rau 425 ° C.Kev hloov pauv ntawm martensite thiab austenite xaus thaum qhov kub nce mus txog 280 ° C, thiab lub workpiece raug tshem tawm ntawm 200 ° C.Lub luag haujlwm ntawm cov pwm tuav yog los tiv thaiv qhov tsis sib xws ntawm thermal expansion thiab contraction thaum lub sij hawm quenching txheej txheem, uas yuav ua rau muaj kev hloov loj hauv cov duab thiab qhov ntev ntawm qhov, ua rau cov khoom seem.Tsis tas li ntawd, nws txhim khu cov thermal hloov efficiency ntawm lub workpiece thiab pwm, txhawb kom ceev ceev quenching thiab txias.
Nyob rau hauv cov ntsiab lus, cov khoom tseem ceeb rau kub stamping muaj xws li cua sov rauv kom ua tau raws li qhov xav tau kub, ib tug kub forming xovxwm rau ceev stamping thiab tuav nrog ib tug ceev ceev cua txias system, thiab kub stamping pwm uas ua tau ob qho tib si tsim thiab quenching theem kom paub meej tsim ib feem. thiab ua kom txias txias.
Lub quenching txias ceev tsis tsuas yog cuam tshuam rau lub sij hawm ntau lawm, tab sis kuj cuam tshuam rau kev hloov dua siab tshiab ntawm austenite thiab martensite.Tus nqi txias txiav txim siab seb cov qauv crystalline yuav tsim thiab muaj feem xyuam rau qhov kawg hardening nyhuv ntawm workpiece.Qhov ntsuas kub tseem ceeb ntawm boron steel yog li 30 ℃ / s, thiab tsuas yog thaum qhov txias txias tshaj qhov ntsuas kub tseem ceeb tuaj yeem tsim cov qauv martensitic tau nce mus rau qhov loj tshaj plaws.Thaum cov cua txias tsawg dua qhov tseem ceeb ntawm qhov txias txias, cov qauv uas tsis yog martensitic xws li bainite yuav tshwm sim hauv cov qauv ua haujlwm crystallization.Txawm li cas los xij, qhov siab dua qhov txias txias, qhov zoo dua, qhov siab dua qhov txias yuav ua rau tawg ntawm cov khoom tsim, thiab qhov tsim nyog txias qhov ntau yuav tsum tau txiav txim siab raws li cov khoom muaj pes tsawg leeg thiab cov txheej txheem ntawm cov khoom.
Txij li thaum tsim cov yeeb nkab txias yog ncaj qha ntsig txog qhov loj ntawm qhov txias txias, cov yeeb nkab txias feem ntau yog tsim los ntawm qhov kev xav ntawm qhov siab tshaj plaws ntawm cov cua sov hloov mus rau qhov zoo tshaj plaws, yog li cov kev taw qhia ntawm cov yeeb nkab tsim txias txias yog qhov nyuaj, thiab nws nyuaj heev. kom tau los ntawm mechanical drilling tom qab ua tiav cov pwm casting.Txhawm rau kom tsis txhob raug txwv los ntawm kev siv tshuab ua haujlwm, cov txheej txheem ntawm kev khaws cov dej ntws ua ntej pwm casting feem ntau yog xaiv.
Vim tias nws ua haujlwm ntev ntawm 200 ℃ txog 880 ℃ ~ 950 ℃ nyob rau hauv qhov txias txias thiab kub hloov pauv, cov khoom kub stamping tuag yuav tsum muaj cov qauv zoo rigidity thiab thermal conductivity, thiab tuaj yeem tiv taus qhov muaj zog thermal kev sib txhuam tsim los ntawm billet ntawm kub siab thiab abrasive coj nyhuv ntawm poob oxide txheej hais.Tsis tas li ntawd, cov khoom siv pwm yuav tsum muaj kev tiv thaiv corrosion zoo rau lub coolant kom ntseeg tau tias cov dej ntws zoo ntawm cov yeeb nkab txias.
Trimming thiab tho
Vim tias lub zog ntawm cov khoom tom qab kub stamping ncav cuag li 1500MPa, yog tias siv cov xovxwm txiav thiab xuas nrig ntaus, cov khoom siv tonnage yuav tsum loj dua, thiab kev tuag txiav ntug hnav yog qhov hnyav.Yog li ntawd, laser txiav units feem ntau yog siv los txiav cov npoo thiab qhov.
4.Common qib ntawm kub stamping hlau
Kev ua tau zoo ua ntej stamping
Kev ua tau zoo tom qab stamping
Tam sim no, qib qib ntawm kub stamping hlau yog B1500HS.Lub zog tensile ua ntej stamping yog feem ntau ntawm 480-800MPa, thiab tom qab stamping, lub zog tensile tuaj yeem ncav cuag 1300-1700MPa.Qhov ntawd yog hais tias, lub zog tensile ntawm 480-800MPa steel phaj, los ntawm kub stamping txoj kev, tuaj yeem tau txais lub zog tensile ntawm txog 1300-1700MPa qhov chaw.
5.Kev siv cov hlau kub stamping
Daim ntawv thov kub-stamping qhov chaw tuaj yeem txhim kho kev sib tsoo kev nyab xeeb ntawm lub tsheb thiab paub txog lub teeb yuag ntawm lub tsheb lub cev dawb.Tam sim no, kub stamping tshuab tau siv rau lub cev dawb ntawm cov neeg caij tsheb, xws li lub tsheb, A pillar, B pillar, bumper, door beam thiab ru tsev rail thiab lwm qhov chaw.Saib daim duab 3 hauv qab no piv txwv qhov chaw haum rau lub teeb - hnyav.
