European tsheb kev lag luam yog nto moo rau nws cov qib siab thiab muaj txiaj ntsig tshiab. Nrog rau kev txhawb nqa lub zog txuag thiab emission txo cov cai, kom txo cov pa roj thiab tsim cov khoom lag luam alloys tau dav siv hauv tsheb tsim. Raws li kev txheeb cais, nyob rau hauv kaum xyoo dhau los, qhov nruab nrab ntawm aluminium siv tau ob npaug, thiab qhov hnyav txo ntawm aluminium alloys tau qhia hauv daim duab 1 hauv qab no. Raws li cov ntsiab lus tsim tsim tsim tshiab, cov txheej txheem no yuav txuas ntxiv mus rau ob peb xyoos tom ntej no.
Nyob rau hauv cov txheej txheem ntawm kev loj hlob sib, aluminium alloys tau ntsib kev sib tw hnyav dua nrog lwm cov ntaub ntawv tshiab, uas tseem tuaj yeem tswj lub siab tom qab tsim nyias. Ib qho ntxiv, muaj cov magnesium, titanium, iav los yog carbon lossis carbon monerata cov ntaub ntawv, cov tom kawg uas tau siv dav hauv aerospace. Tam sim no lub tswvyim ntawm ntau cov khoom tsim qauv tau sib xyaw ua ke tsim, thiab kev siv zog yog ua kom tau cov ntaub ntawv uas tsim nyog. Ib qho kev sib tw tseem ceeb yog qhov teeb meem ntawm kev sib txuas, thiab ntau yam kev daws teeb meem, cov qauv siv hluav taws xob (Lotus Elise), tus qauv nyias nyias), cov qauv nyias nyias , Jaguar, rovern), Raug tshem tawm (DC-E chav kawm, Renault, Peugeot) thiab lwm cov qauv txheej txheem qauv txheej txheem. Daim duab 2 qhia txog cov sib txuas ntawm txhuas siv hauv tsheb.
BiW Tsim Lub Tswv Yim
Lub cev-nyob rau hauv-dawb yog qhov hnyav tshaj plaws ntawm lub tsheb uas muaj pa, tus account rau 25% mus rau 30% ntawm lub tsheb yuag. Muaj ob txoj kev tsim qauv hauv lub cev-hauv-dawb tsim.
1. "Cov ntaub ntawv xaib tsim qauv" rau cov tsheb me me thiab nruab nrab: Audi A8 yog ib qho piv txwv, lub cev hauv cov hnyav dawb 277 kg, muaj 59 tus txheej txheem (66 daim ntawv) thiab 170 daim hlau (177 kg). Lawv tau koom nrog los ntawm riveting, mig vuam, laser vuam, lwm hybrid vuam, gluing, thiab lwm yam.
2. "Tuag-forged sheet hlau monocoque qauv" rau nruab nrab rau cov ntawv thov loj tsheb loj: piv txwv li, Jaguar XJ (X350), 2002 qauv (raws li qhia hauv daim duab 4 hauv qab no), 295 KG Masse "steeled (21 kg), 15 kg) thiab 273 daim ntawv hlau seem (259 kg). Cov hau kev sib txuas suav nrog kev sib koom tes, riveting, thiab mig vuam.
Daim ntawv thov ntawm txhuas alloy rau lub cev
1. Lub hnub nyoog Hardened Al-MG-Si Alloy
Qhov 6000 series alloys muaj magnesium thiab silicon thiab tam sim no siv hauv lub cev lub cev raws li A6016, A6111 thiab A6181A. Hauv Tebchaws Europe, 1-1.2mm EN-6016 muaj cov kev tsim kho zoo dua thiab xeb tsis kam thiab yog siv dav.
2. Tsis yog-tshav kub kho tau zoo al-mg-mn alloy
Vim tias nws tshwj xeeb siab tawv tawv tawv, al-mg-mn-mn-mn-mn-mn alloys ua pov thawj zoo heev firmility thiab siab siv nyob rau hauv automotive kub los yog hydroformed leeg. Daim ntawv thov nyob rau hauv chassis lossis log yog tseem ua tau zoo dua vim tias kev txo qis ntawm unseplung txav chaw ntxiv thiab txo cov suab nrov.
3. Aluminium profile
Hauv Tebchaws Europe, tag nrho cov ntsiab lus tsheb tshiab tshiab tau npaj raws li txhuas cov qauv tsim, piv txwv li, txhuas alloy thav duab thiab cov kev sib txuas nyuaj. Lawv lub peev xwm loj rau cov qauv tsim qauv thiab kev sib xyaw ua kom lawv zoo tshaj rau kev tsim cov nqi-ua tau zoo. Vim tias quenching yuav tsum tau thaum lub sij hawm extrusion, nruab nrab lub zog 6000 thiab siab zog 7000 hnub nyoog nyuaj alloys yog siv. Firstability thiab lub zog kawg yog tswj tau los ntawm lub hnub nyoog hardening los ntawm cov cua sov tom ntej. Aluminium alloy profiles yog tsuas yog siv nyob rau hauv kev tsim qauv, tsoo nqaj thiab lwm yam kev sib tsoo.
4. Aluminium casting
Cov castings yog cov feem ntau siv siv dav siv cov khoom siv txhuas hauv tsheb, xws li cov cav hauv lub cav, lub tog raj kheej hau thiab cov voos tshwj xeeb thiab tshwj xeeb tshaj plaws. Txawm tias cov tshuab tuag txawm tias, uas tau nce ntxiv lawv cov lag luam sib tw hauv Tebchaws Europe, yog hloov mus rau txhuas cov duab vim muaj zog thiab ua kom ntev. Nyob rau tib lub sijhawm, Aluminium castingings kuj tau siv nyob rau hauv cov qauv tsim qauv, ncej, thiab cov kev tsim qauv, thiab kev kub siab Casting ntawm Tshiab Alloys tau ua tiav lub zog thiab du.
Aluminium yog cov khoom siv ntawm kev xaiv rau ntau txoj kev siv chassis, lub cev thiab ntau yam ntom ntom nti, zoo formability thiab zoo corrosion tsis kam. Aluminium siv nyob rau hauv lub cev qauv qauv tsim tuaj yeem ua tiav tsawg kawg 30% kev txo phaus nyob rau hauv lub rooj sib tham ua tau zoo. Tsis tas li, txhuas alloys tuaj yeem siv rau feem ntau ntawm cov npog tam sim no. Muaj qee kis nrog cov siab muaj zog yuav tsum tau, 7000 series alloys tseem tuaj yeem tswj cov txiaj ntsig zoo. Yog li ntawd, rau cov ntawv thov siab, aluminium alloy hnyav txo cov kev daws teeb meem yog txoj kev lag luam tshaj plaws.
