Lub Invisible Battlefield uas tsim txhua yam kev paub
Thaum koj xaub mus rau hauv lub tsheb fais fab tshiab thiab pom kev tsav tsheb kom ntseeg siab nyeem 600 km, lossis thauj ib lub lim tiam lub ntxhua khaub ncaws mus rau hauv lub tshuab ntxhua khaub ncaws uas tig ntawm 1 600 rpm tseem yws yws zoo li lub tub yees, lossis saib lub installer nqa lub tshuab cua sab nraum zoov mus txog tsib lub davhlau ntawm ntaiv tsis tawg hws, koj tau pom qhov kev vam meej ntawm lub teeb yuag.
Rau kaum xyoo dhau los, cov ntawv xov xwm tau ua kev zoo siab rau cov roj teeb loj dua, cov chips ntse dua, thiab software flashier. Txawm li cas los xij, hauv qab ntawm qhov chaw uas cov neeg siv tsis tau kov, cov txheej txheem txhuas thiab titanium diecasting tau rov sau dua cov cai. Cov engineers pom tsis pom shaving 0.1 hli ntawm phab ntsa tuab, poob 0.5 kg ntawm qhov loj, thiab ntsiag to rov kho lub zog noj, suab nrov, ua haujlwm ntev, thiab tus nqi kom txog thaum cov khoom kawg tsuas xav tias "zoo dua."
Vim Li Cas Tuag Casting Yeej: Ib Txhaum, Peb Yeej
Tuag casting khwv tau nws qhov chaw nyob rau hauv lub plawv ntawm lub teeb yuag tsim los ntawm kev xa ib tug yuav luag tsis yooj yim sua trifecta.
• Precision: Highpressure tuag casting (HPDC) ib txwm tuav qhov ntev ntev ntawm ± 0.05 hli, tshem tawm cov machining theem nrab rau feem ntau nta.
• Lub zog: Vacuumassisted tuag casting ntxiv rau kev kho cua sov thawb AlSi alloys mus rau 280 MPa yield zog-nrog rau cov hlau me me.
• Tus nqi: Ntawm qhov ntim, tus nqi ib gram ntawm aluminium diecasting poob qis dua 0.018 RMB, kwv yees li 40% tsawg dua CNC machining tib geometry.
Thaum koj tuaj yeem sib dua, muaj zog dua, thiab pheej yig dua tib lub sijhawm, cov lus nug nres yog "Peb Puas Yog?" thiab dhau los ua "Peb tuaj yeem ceev npaum li cas?"
Automotive: Ib qho kev cuam tshuam los ntawm cov pem hauv ntej pem hauv ntej mus rau cov tais roj teeb
Xav txog lub tsheb ua ib lub cev pob txha nyob. Cov kev phais loj tshaj plaws tshwm sim hauv qhov chaw uas cov neeg caij tsheb tsis pom.
Tesla's Model Y rear underbody yog tus menyuam daim ntawv tshaj tawm. Yav dhau los, ntu no xav tau ntau tshaj 70 stampings thiab 200 qhov chaw welds. Niaj hnub no, ib tug 6 000 t diecasting xovxwm tsim tag nrho cov txhuas feem hauv 90 vib nas this. Qhov chaw poob los ntawm 70 mus rau 1, lub sij hawm hauv khw hauv pem teb poob 40%, thiab torsional tawv nce 30%.
Lub kiv puag ncig nthuav tawm sab nraud. NIO's ET5 siv lub tshuab nqus tsev vacuumdiecast AlSiMg rear subframe uas yog 25% sib zog dua nws cov weldedsteel ua ntej; NVH poob los ntawm 3 dB, tig lub suab nrov ntawm txoj kev mus rau hauv qhov chaw nyob deb. Cov tais roj teeb -ib zaug txhuas extrusion mob hnyav frictionstirwelded- tam sim no yog ib qho kev ua haujlwm siab uas hnyav 15% tsawg dua thaum ntsib IP68 sealing.
Cov Khoom Siv Hauv Tsev: Los ntawm Plhaub mus rau LoadBearing Hearts
Tib physics plays tawm hauv chav ntxhua khaub ncaws thiab ntawm lub sam thiaj phab ntsa.
Lub tshuab ntxhua khaub ncaws sab nrauv molded los ntawm glassfiberreinforced PP xav tau 4 hli ntawm phab ntsa tuab kom muaj sia nyob 1 600 rpm tig mus. Hloov mus rau AlMgSi diecasting thiab phab ntsa tuaj yeem ua rau 1.8 hli. Lub tshuab tso 4 kg, shipping zog poob 12%, thiab lub stiffer hlau tub dauv perceived suab nrov ntawm 62 dB (A) mus rau 54 dB (A).
Cua txias compressor brackets ib zaug nyiam cam khwb cia hlau- hnyav, rustprone, thiab overengineered. Lub titanium (Ti6Al4V) diecasting yog ib nrab ntawm qhov loj, muaj sia nyob 720 h ntawm cov tshuaj ntsev tsuag tshuaj tiv thaiv 48 h rau hlau, thiab txiav qhov ua tsis tiav los ntawm 60% hauv cov khw muag khoom SouthAsian. Txawm tias cov tub yees cua txias tau txais txiaj ntsig: 1.2 hli aluminium casting txo cov cua sib txhuam 8%, trimming 3 W ntawm kiv cua zog thiab txuag 26 kWh ib xyoo rau cov neeg siv.
Tom qab kab hlau rhuav: Alloys thiab Txheej Txheem Alchemy
Tsis muaj qhov no yuav ua haujlwm yam tsis muaj metallurgists thiab cov txheej txheem engineers obsessing dhau qhov tsis pom.
• Ib tug tshiab AlSiFeMg alloy ncav cuag 170 W / (m·K) thermal conductivity tom qab ib tug yooj yim 180℃hnub nyoog, zoo meej rau lub cev muaj zog vaj tse uas muab ob npaug rau cua sov dab dej.
• A lean Ti4Al2V1Mo qib hloov cov nqi kim vanadium nrog FeMo, txiav raw khoom nqi 30% thiab widening lub qhov rais casting los ntawm 40 degree.
• Semisolid tuag casting (thixocasting) shears sau ceev los ntawm 60%, shrinks porosity hauv qab 0.1%, thiab xa cov chaw npaj rau anodizing yam tsis muaj polishing.
Daim Ntawv Qhia Kev Lag Luam: Leej Twg Ua Tag Nrho Qhov Tsis Pom Zoo?
• Automotive chain: LK Group's 6 000 t IDRA gigapresses, Wenzhong's rear subframes for NIO, Tuopu's onepiece rear floors for Tesla.
• Cov khoom siv: Midea's Meizhi titanium compressor brackets, Gree's monobloc aluminium condenser tais, Haier's AlMg spin tubs hauv "Essence Wash" washers.
• Khoom siv: Lizhong's heattreatfree AlSi alloy, Baoti's lowcost Ti bar Tshuag, Xusheng's hybrid extrusiondiecasting daws.
Lub hom phiaj ntawm lub teeb tsis yog "sib dua," Nws yog "zoo dua"
Aluminium thiab titanium tuag castings yog hu ua "tsis pom lub zog" tsis yog vim lawv nkaum, tab sis vim lawv nqus qhov nyuaj thiab rov qab yooj yim: qis dua kilowatthours, tsawg dua decibels, lub neej ntev, cov nqi me.
Thaum lub nthwv dej tom ntej ntawm zaj dab neeg yuav trumpet solidstate roj teeb, AI inverters, thiab heatpump hlwb, cov pob txha hlau uas ntsiag to yuav ua lawv txoj hauj lwm - cia lub roj teeb tawm ntawm 10 kg ntawm armor tom qab, cia lub tshuab ntxhua khaub ncaws tsis ua las voos thoob hauv pem teb, cia ib chav nyob sab nraum zoov shrug tawm ntawm typhoon.
Lub teeb yuag kiv puag ncig yuav tsis nres, tab sis nws twb kawm tiav los ntawm showboating mus rau infrastructure. Leej twg masters lub xeem 0.1 hli ntawm phab ntsa thickness thiab qhov kawg 0.5 kg ntawm rho tawm yuav yeej lub ntsiag to, tsis tau hnyav tshaj, pom zoo ntawm tag nrho cov:
"Nws tsuas xav txawv."
