Tau ntev, steel tau ua lub hauv paus ntawm kev lag luam tsheb. Ntawm cov khoom siv hauv lub cev, cov ntaub ntawv steel muaj ntau dua 85%. Txawm hais tias kev siv cov aluminium alloys, magnesium alloys, plastics thiab composite cov ntaub ntawv nyob rau hauv lub tsheb manufacturing txuas ntxiv mus, high-strength steel tseem yog tam sim no kev xaiv vim nws qhov zoo xws li qhov hnyav txo qhov peev xwm, siab sib tsoo lub zog nqus, siab qaug zog, thiab siab formability. Basic structural khoom rau tsheb lub cev. Xws li cov hlau phaj tuaj ntawm Tebchaws Europe! EU emission qauv tau yuam kom lawv txo qhov hnyav ntawm lawv lub tsheb.
Cov txheej txheem kub txheej txheem coj cov kev hloov pauv hloov pauv rau cov ntawv thov steel muaj zog
Txawm hais tias cov pa hlau muaj zog muaj zog tensile thiab tawm los, nws tsis tsuas yog muaj peev xwm deformation tsis zoo nyob rau hauv chav tsev kub, tab sis kuj muaj qhov nqaim yas deformation ntau yam, yuav tsum muaj lub zog stamping siab, thiab nws yuav ua rau tawg. Nyob rau tib lub sijhawm, lub springback ntawm cov khoom tom qab molding nce, uas ua rau tsis zoo seem thiab cov duab stability ntawm qhov chaw. Yog li ntawd, ib txwm tsim txoj kev nyuaj los daws cov teeb meem uas tau ntsib nyob rau hauv high-strength steel daim hlau nyob rau hauv lub tsheb lub cev manufacturing, thiab kub forming technology yog daws cov teeb meem no.
Cov txheej txheem thermoforming yog kom sov cov hlau phaj siab ntawm chav tsev kub mus rau 880-950 degree , ces xa lawv mus rau hauv pwm nrog lub tshuab cua txias sab hauv rau stamping, thiab thaum kawg txias lawv sai sai rau harden lub stamped qhov chaw. Thermoforming thev naus laus zis ua kom yooj yim tswj hwm ntawm qhov ntev, txhim kho lub zog thiab txo qhov hnyav.
High-lub zog steelcov khoom ua los ntawm cov txheej txheem thermoforming yog muab faib rau hauv pem hauv ntej longitudinal beams, rear longitudinal beams, A-pillars, B-pillars, central qhov, pem hauv ntej phab ntsa, pem teb kab teeb thiab lwm yam. Cov khoom no yog cov qauv kev nyab xeeb ntawm lub cev thiab tuav lub luag haujlwm tseem ceeb ntawm kev tiv thaiv cov neeg caij tsheb. Yog li ntawd, lawv yuav tsum muaj cov cuab yeej ua haujlwm siab, molding zog, vuam zog, tshwj xeeb tshaj yog kev nkag siab zoo thiab muaj peev xwm nqus tau lub zog.
Lub thicker lub tsheb lub cev steel phaj yog, qhov zoo dua. "Thiab" thiab "muaj zog" yog qhov sib txawv.
Lub thicker lub tsheb lub cev steel phaj yog, qhov zoo dua. Cov phaj tuab tuab heev yuav tsis tsuas yog nce qhov hnyav ntawm lub cev ntawm lub tsheb, cuam tshuam rau kev lag luam roj thiab kev tuav ruaj khov, tab sis kuj ua rau cov neeg caij tsheb uas yuav tsum tau tiv thaiv kom ris lub nra ntau vim qhov tsis tsim nyog lub zog faib. Nws muaj lub luag haujlwm nqus lub zog ntau dhau, yog li nws tsis tuaj yeem ua lub luag haujlwm tiv thaiv zoo.
Yog li ntawd, kev tsim lub cev lub cev niaj hnub ua raws li kev thov tsim qauv ntawm "siv cov hlau zoo ntawm kev txiav ntug". Ntawm qhov tod tes, lub tsheb lub cev yog lub teeb yuag mus rau qhov siab tshaj plaws thaum ua kom ntseeg tau tias kev sib tsoo kev nyab xeeb ntawm lub cev lub tsheb tau ntsib; ntawm qhov tod tes, los ntawm qhov tsim nyog kev faib tawm ntawm lub zog ntawm lub cev qhov chaw, lub hom phiaj ntawm absorbing zog nyob rau hauv ntau qhov chaw thiab tiv thaiv cov neeg nrog caij compartment yog tiav.
"Variable cross-section" thiab "variable zog" zoo kawg nkaus reconcile "kev sib cav" ntawm kev sib tsoo kev nyab xeeb thiab lub teeb yuag
High-strength steel siv cov txheej txheem kub txheej txheem muab lub zog "riam phom" rau niaj hnub tsheb lub cev tsim. Nws cov khoom siv kho tshuab zoo txhim kho kev nyab xeeb ntawm lub tsheb thiab lub zog thiab nruj ntawm lub cev lub tsheb. Nyob rau tib lub sijhawm, nws paub txog lub teeb yuag ntawm lub tsheb lub cev thiab tswj lossis txawm tias txhim kho kev ua haujlwm zoo ntawm lub tsheb. , acoustic kev ua tau zoo, tuav ruaj khov, roj kev lag luam, thiab lwm yam hauv cov txheej txheem kub txheej txheem, muaj ob qhov tseem ceeb "hloov" - "hloov hauv ntu" thiab "hloov lub zog" uas tso cai rau lub cev steel phaj ua "nyias" thiab "muaj zog".
Lub hom phiaj ntawm kev hloov pauv ntawm ntu ntu yog txhawm rau ua kom lub teeb yuag ntawm lub tsheb lub cev los ntawm kev hloov pauv hauv ntu ntu tuab thaum ua kom ntseeg tau tias kev sib tsoo kev nyab xeeb ntawm lub cev lub tsheb tau ntsib. Los ntawm kev tswj xyuas meej ntawm cov rollers thaum dov, nws muaj peev xwm ua tiav kev hloov pauv tsis tu ncua ntawm cov phaj steel. Piv nrog rau cov tsoos qhov chaw nrog tib cov ntaub ntawv tuab thiab laser welded qhov chaw, qhov tsis tu ncua sib txawv ntawm cross-section steel phaj qhov chaw tsis tsuas yog muaj kev sib tsoo zoo tib yam, tab sis kuj thiab lub teeb yuag yog qhov tseem ceeb.
Lub zog sib txawv tau ua tiav lub hom phiaj ntawm kev nqus lub zog hauv qhov sib txawv thiab tiv thaiv cov neeg caij tsheb los ntawm kev faib khoom tsim nyog ntawm lub zog ntawm lub cev. Piv txwv li, Touran L tshiab siv cov thev naus laus zis thev naus laus zis thev naus laus zis nyob rau hauv cov kab nruab nrab ntawm qhov ntev. Nyob rau hauv qhov kev tshwm sim ntawm ib tug rear-kawg kev sib tsoo, lub rear ntawm lub rear longitudinal beam tuaj yeem deform thiab nqus tau lub zog, thaum lub zog siab ntawm lub hauv ntej ntawm lub rear longitudinal beam xyuas kom meej cov khoom tseem ceeb xws li cov neeg caij tsheb compartment thiab roj tank. Cov khoom tsis raug nyem. Nws cov qauv kev ua kom zoo ntawm lub cev yog qhov cuam tshuam ncaj qha ntawm German zoo. Txij li cov thev naus laus zis thev naus laus zis thev naus laus zis thev naus laus zis yuav tsum muaj pwm tsim thiab txheej txheem kev ruaj ntseg dua li cov khoom siv thermoformed zoo tib yam, tsuas yog ob peb lub tuam txhab tsheb thoob ntiaj teb tau paub nws.
Nrog rau daim ntawv thov ntawm high-strength steel thiab advanced processing technology, lub teeb yuag lub cev tsim tau los ua lub ntsiab ntawm niaj hnub tsheb tsim. Raws li kev taw qhia ntawm cov ntsiab lus siab dua, kev nyab xeeb ntawm lub tsheb tsis yog tsuas yog tsis poob vim qhov hnyav ntawm lub cev ntawm lub tsheb, tab sis kuj tuaj yeem tiv thaiv kev ncaj ncees ntawm cov neeg caij tsheb mus rau qhov ntau dua thaum muaj kev sib tsoo. Lub cev lub cev lub cev muaj zog tuaj yeem txhim kho kev tswj xyuas qhov tseeb, txo qis kev siv roj thiab txo nqi tsheb.
