Yuav CNC Machining Hloov Casting Thiab Stamping hauv Automobile Manufacturing?

1. Kev sib piv ntawm cov yam ntxwv ntawm cov txheej txheem: Peb- txoj kev ua si ntawm qhov tseeb, kev ua haujlwm zoo, thiab tus nqi: CNC machining yog tus qauv rau qhov raug thiab ntau yam.
Nrog lub tshuab computer tswj cov lej, CNC machining tuaj yeem tswj kev txav ntawm lub cuab yeej mus rau hauv ± 0.01mm, thiab qhov roughness ntawm qhov chaw tuaj yeem ncav cuag Ra <0.4 μm, uas yog qhov zoo dua li cov tsoos casting thiab stamping txoj kev. Nws cov txiaj ntsig tseem ceeb yog:
Tsim kev ywj pheej: Nws tuaj yeem ua haujlwm nrog cov txheej txheem nyuaj, cov qauv hollow, thiab cov khoom tsis sib xws xws li turbocharger blades, carbon fiber gearbox ncej brackets, thiab lwm yam khoom hnyav yam tsis siv pwm los tig cov duab kos rau hauv cov khoom tiav.
Adaptability ntawm cov ntaub ntawv: Nws tuaj yeem ua haujlwm nrog ntau yam ntawm cov khoom siv hnyav, suav nrog txhuas alloys, magnesium alloys, titanium alloys, siab - steels, thiab cov ntaub ntawv sib xyaw. Qhov no ua tau raws li cov kev xav tau sib txawv rau cov khoom zoo hauv lub tsheb sib sib zog nqus.
Flexible ntau lawm: Hloov qhov kev pab cuam CNC ua rau nws yooj yim los hloov ntawm cov qauv khoom. Qhov no yog qhov zoo rau kev ua cov khoom me me ntawm cov khoom sib txawv, zoo li sai sai tsim lub zog tshiab lub tsheb roj teeb pob.
Tab sis kuj tseem muaj teeb meem loj nrog CNC machining:
Cov ntaub ntawv pov tseg: Thaum txiav, tsuas yog 50% mus rau 70% ntawm cov ntaub ntawv raw yog siv, thiab cov seem yog poob li chips, uas nce nqi.
Kev tsim khoom ua haujlwm zoo npaum li cas: Nws yuav siv sijhawm ntev los ua cov txheej txheem ib zaug. Piv txwv li, CNC machining ntawm aluminium alloy lub tog raj kheej lub tog raj kheej siv sijhawm 4 mus rau 8 teev, uas ua rau nws nyuaj ua kom tau raws li qhov xav tau ntawm cov khoom loj -.
Tus nqi ntawm cov khoom siv: Tsib -axis linkage machining centers thiab lwm yam khoom siv siab- kawg yog kim thiab xav tau cov neeg ua haujlwm nrog ntau yam kev paub, uas ua rau tus nqi ib chav tsev ntau dua.
Casting txheej txheem: nrhiav qhov sib npaug ntawm cov qauv nyuaj thiab tus nqi
Casting yog txheej txheem ntawm pouring hlau molten rau hauv pwm. Nws tuaj yeem ua tau ntau yam, xws li xuab zeb casting, tuag-casting, thiab qis- siab casting. Nws tus nqi tseem ceeb yog nyob rau hauv:
Ua cov khoom nrog ntau cov duab sib txawv: Nws tuaj yeem ua rau sab hauv hollow, nyias- cov khoom siv phab ntsa thiab cov khoom siv ntxiv, suav nrog cov tsheb cav lub tog raj kheej thiab cov gearbox vaj tse, nrog rau theem ntawm cov qauv complex uas siab tshaj CNC machining.
Kev siv cov khoom siv: Yuav luag tag nrho cov khoom siv raw yog siv, uas txo cov nqi khoom los ntawm ntau. Qhov no yog qhov tshwj xeeb tshaj yog zoo rau kev siv cov khoom siv hnyav xws li aluminium alloys thiab magnesium alloys ntawm qhov loj.
Kev ua tau zoo hauv kev tsim khoom: Tuag- thev naus laus zis tuaj yeem ua rau ib yam khoom hauv 1 mus rau 3 feeb xwb, uas yog qhov zoo rau kev tsim khoom loj nrog ntau tshaj 100,000 daim txhua xyoo. Piv txwv li, Tesla's integrated tuag-casting lub cev hauv qab vaj huam sib luag muab 70 daim rau hauv ib qho, uas ua rau ntau lawm 300% ntau npaum.
Tab sis cov txheej txheem casting muaj qee qhov teeb meem:
Cov kev txwv ntawm qhov raug: Qhov kam rau ua feem ntau yog ntau tshaj ± 0.1mm, thiab qhov roughness ntawm Ra yog ntau dua los yog sib npaug rau 3.2 μ m, yog li qhov yuav tsum tau machined los yog polished dua.
Tus nqi ntawm cov pwm: exorbitant-pressure casting pwm tuaj yeem raug nqi ntau pua txhiab rau ntau lab yuan, thiab cov nuj nqis ntau dhau ntawm kev hloov tus qauv ua rau nws nyuaj rau ua cov khoom me me.
Cov khoom ntawm cov khoom: tej zaum yuav muaj teeb meem nrog cov castings, xws li shrinkage thiab porosity, thiab cov neeg kho tshuab zoo yuav tsum tau kho los ntawm kev kho cua sov los yog cov txheej txheem T6 ntxiv dag zog.
Stamping txheej txheem: ib txoj hauv kev zoo los ua cov ntawv nyias nyias
Stamping siv cov pwm los tso siab rau ntawm cov ntawv hlau, uas ua rau lawv khoov rau hauv cov duab zoo. Nws yog ib txoj hauv kev los ua cov ntawv hlau rau cov tsheb.
High-kev ceev ntau lawm: tuaj yeem stamp ntau zaus hauv ib feeb, ua kom nws zoo rau kev ua lub qhov rooj tsheb, lub cav npog, lub log arches, thiab lwm yam loj.
Tus nqi kom zoo dua: Tus nqi ntawm cov pwm yog tsawg rau txhua tus, thiab tus nqi ib thooj poob sai sai thaum ntau lawm nce. Piv txwv li, tus nqi ntawm stamped qhov chaw rau tsheb qhov rooj sab hauv panels tej zaum yuav pheej yig li ob peb yuan ib thooj.
Qhov zoo ntawm qhov chaw: Qhov saum npoo ntawm cov khoom stamped yog du thiab tsis xav tau polishing ntxiv, uas yog raws nraim li txheej txheem txheej xav tau.
Tab sis stamping tshuab muaj qee qhov teeb meem, xws li:
Txwv rau cov khoom tuab: tsuas yog ua haujlwm ntawm cov ntawv nyias nyias uas yog 0.1 txog 6 hli tuab; nws tsis tuaj yeem ua cov khoom siv nrog cov phab ntsa tuab.
Kev tsim qauv nyuaj npaum li cas: Cov chaw nyuaj xav tau ntau tshaj li ib txoj haujlwm los ua haujlwm, thiab cov khoom siv ductility txwv qhov sib sib zog nqus rub mus.
Tus nqi ntawm kev hloov pwm: Kev tsim kho pwm rau cov khoom tshiab yuav siv sij hawm ntev thiab raug nqi ntau, yog li nws tsis zoo rau cov xwm txheej uas koj yuav tsum tau hloov sai sai.
2. Yuav ua li cas hauv kev lag luam: Cov piv txwv ntawm kev sib koom tes ua haujlwm
Case 1: Tesla Integrated Tuag Casting thiab CNC ua hauj lwm ua ke
Tesla Model Y siv 6000-tuj tuag-casting tshuab los ua ib qho kev sib xyaw ua ke hauv qab phaj uas sib xyaw ua ke 70 yam hauv ib qho. Qhov no ua rau kev tsim khoom 300% ntau dua thiab txo cov nqi los ntawm 40%. Txawm li cas los xij, qhov chaw tuag-casting tseem xav tau CNC machining ntawm cov khoom sib dhos tseem ceeb:
Precision them nyiaj: Ib tsib -axis machining center yog siv los ua precision machining ntawm tuag-casting qhov chaw. Qhov no ua kom paub tseeb tias lub roj teeb pob thiab lub kaw lus ncua kev kawm haum ua ke nrog qhov tseeb ntawm ± 0.05mm.
Kev kho qhov tsis xws luag: Txhim kho cov teeb meem xws li porosity thiab shrinkage uas yuav tshwm sim thaum tuag- txheej txheem casting kom cov khoom txhim khu kev qha.
Kev ua haujlwm txuas ntxiv: Ntxiv cov qhov threaded, positioning pins, thiab lwm yam nta kom tuag -casting pieces kom lawv tuaj yeem txuas mus rau lwm qhov chaw.
Case 2: CNC tshuab ua lub cev carbon fiber ntau ntawm BMW i-series
Lub cev ntawm BMW i3 yog ua los ntawm carbon fiber reinforced yas (CFRP), thiab lub ntsiab txoj kev nws yog ua los ntawm CNC machining:
Txiav ua ntej- cov khoom siv impregnated: Lub CNC laser txiav tshuab txiav cov pa roj carbon fiber ntau ua ntej- cov khoom impregnated rau hauv cov qauv tsim nrog qhov tsis raug tsawg dua 0.1 hli.
Kev Ua Haujlwm: Lub CNC robotic caj npab cia li tso cov pa roj carbon fiber ntau hauv ib txoj hauv kev uas ua kom cov kev taw qhia fiber ntau nyob rau hauv txoj kab nrog lub zog kev taw qhia, uas ua rau cov qauv muaj zog.
Tom qab compression molding, CNC milling yog siv los ua mounting qhov, qhia rails, thiab lwm yam qauv nyob rau hauv lub carbon fiber qhov chaw. Qhov kam rau ua yog khaws cia hauv ± 0.02mm.
Case 3: Ua hydrogen cia tank tawm ntawm titanium alloy rau Toyota hydrogen roj cell tsheb
Lub hau kawg ntawm Toyota Mirai lub tank hydrogen yog ua los ntawm titanium alloy thiab yog CNC machined.
Sib piv cov khoom ntawm cov ntaub ntawv: Titanium alloy yog ib qho nyuaj heev thiab tsis ua kom sov zoo, yog li ntawd raug casting zoo li yuav tawg. Tsawg-kub txiav tshuab ua rau CNC machining ruaj khov.
Sealing nto precision machining: Ib tsib -axis linkage machining center ua ultra- precision machining ntawm lub sealing nto ntawm lub hau kawg. Qhov kev ua yuam kev flatness tsawg dua los yog sib npaug li 0.002mm, uas ua rau cov dej ntws tawm qis dua 0.1ppm.
Lub teeb pom kev zoo tsim qauv: CNC ceev prototyping tuaj yeem pab nrog topology optimization tsim rau hydrogen cia tso tsheb hlau luam, uas txiav lawv qhov hnyav los ntawm 25% thaum ua kom lawv muaj zog.
