Yadda Simintin Zuba Jari ke ba da damar yin nauyi a cikin Kera Motocin Lantarki

Juyin juzu'in motocin lantarki yana sake fasalin masana'antar kera motoci ta duniya cikin saurin da ba a taɓa yin irinsa ba. Nan da shekarar 2030, ana hasashen motocin lantarki za su yi lissafin sama da kashi 30% na sabbin siyar da motoci a duk duniya, bisa ka'idojin doka, buƙatun mabukaci don dorewa, da saurin ci gaba a fasahar batir. Duk da haka a ƙarƙashin kanun labarai game da sunadarai na baturi da cajin kayayyakin more rayuwa ya ta'allaka ne da ƙalubalen injiniya wanda ke ƙayyade nasarar EV: nauyi .

Kowane gram na abin hawa yana tasiri kai tsaye kewayon tuki - ma'auni mafi mahimmanci guda ɗaya don ɗaukar mabukaci na EV. Nazarin da Hukumar Makamashi ta Duniya (IEA) ta yi ya nuna cewa raguwar 10% na nauyin abin hawa zai iya inganta kewayon EV da 6-8%. Wannan yana sanya nauyi ba kawai ingantawa ba amma mahimmancin mahimmanci ga masana'antun EV. Kuma a tsaka-tsakin daidaito, aiki, da rage nauyi, simintin saka hannun jari ya fito a matsayin fasaha mai mahimmanci mai ba da dama.

Mahimmancin Ƙarfafa nauyi a cikin EV Design

Ba kamar motocin konewa na ciki (ICE) ba, inda ake karɓar tubalan injuna masu nauyi da watsawa azaman masu daidaitawa, falsafar ƙira ta EV tana ɗaukar kowane sashi azaman damar rage nauyi. Akwatin ragi na abin hawa, mahalli na mota, shingen inverter, tsarin baturi, da abubuwan dakatarwa duk makasudi ne don ɗaukar nauyi mai ƙarfi.

Hanyoyin masana'antu na al'ada suna fuskantar iyakoki na asali:

• Yin simintin yashi yana haifar da m saman da bango mai kauri (yawanci 6-10mm), yana ƙara yawan da ba dole ba.
• Die simintin yana ba da bangon sirara amma iyakacin zaɓin gami da tsadar kayan aiki don haɗaɗɗun geometries
• Machining daga billet sharar gida 40-60% na abu kuma ba zai iya samar da ciki cavities

Simintin saka hannun jari (bataccen simintin kakin zuma) ya karya ta waɗannan iyakoki ta hanyar ba da damar kauri bango kamar sirara kamar 3.0mm, hadaddun geometries na ciki, da kewayon gami da yawa - duk tare da ƙarewar saman da ke rage aikin bayan aiki.

Zuba Jari na Aluminum: Abubuwan Zaɓa na EVs

Aluminum alloys, musamman A356.2 (Al-Si7Mg), sun zama kayan da aka zaba don EV tsarin da powertrain aka gyara. Tare da girman kawai 2.68 g/cm³ - kusan kashi ɗaya bisa uku na ƙarfe na simintin ƙarfe - aluminum yana ba da ma'auni mai ƙarfi-zuwa nauyi lokacin da aka kula da zafi sosai.

Maɓalli na aluminum EV da aka samar ta hanyar simintin saka hannun jari sun haɗa da:

1. Rage Gidajen Gearbox : Akwatin gear-gudu ɗaya a yawancin EVs yana buƙatar mahalli mai nauyi da tsayin daka. Zuba jari-simintin A356.2 aluminum ya cimma kauri na bango na 3.5mm yayin da yake kiyaye tsattsauran ra'ayi da ake buƙata don daidaitaccen daidaita kayan aiki. Maganin zafi na T6 (mafifi a 540 ° C, tsufa a 155 ° C) yana haifar da ƙarfin juzu'i wanda ya wuce 228 MPa - ya isa ga aikace-aikacen gearbox tare da manyan nauyin juzu'i.

2. Inverter da Gidajen Motoci : Kayan lantarki na EV suna haifar da babban zafi wanda dole ne a watsar da shi sosai. Ƙarfin wutar lantarki na Aluminum na 150 W/m·K - fiye da sau uku na simintin ƙarfe - ya sa ya dace don shinge inverter. Yin simintin saka hannun jari yana ba da damar haɗa fins masu sanyaya da tashoshi na ciki kai tsaye zuwa cikin gidaje, kawar da buƙatar raƙuman zafi daban.

3. Abubuwan Rukunin Baturi : Yayin da cikakkun fakitin baturi suna amfani da extruded da hatimi aluminium, madaidaicin simintin saka hannun jari, wuraren hawa, da akwatunan haɗin gwiwa a cikin tsarin baturi suna amfana daga ikon aiwatarwa don ƙirƙirar hadadden geometries tare da ƙaramin nauyi.

4. Dakatarwa da Brackets na Chassis : EV-takamaiman ƙirar dakatarwa galibi suna buƙatar braket na al'ada waɗanda ke ɗaukar gyare-gyaren lissafin lissafi da mafi girma mara nauyi daga samfuran baturi. Simintin saka hannun jari yana samar da waɗannan sassan tare da ingantattun topology - abu ne kawai inda binciken damuwa ya buƙaci shi.

Madaidaicin Wanda Yayi Tasirin NVH Kai tsaye

Motocin lantarki suna aiki kusan shiru idan aka kwatanta da motocin ICE, suna yin Noise, Vibration, da Harshness (NVH) mafi mahimmanci fiye da kowane lokaci. Abubuwan da a baya aka rufe su da hayaniyar inji yanzu suna fitattun ji.

Daidaitaccen girman simintin saka hannun jari - yawanci juriya na CT6 akan ISO 8062 - yana tabbatar da cewa an samar da kujeru masu ɗaukar nauyi, ramukan kaya, da musaya masu hawa zuwa tsakanin ± 0.02mm. Wannan madaidaicin yana rage rashin daidaituwar kayan aiki, yana rage watsawar girgiza, kuma yana kawar da ƙananan motsin da ke haifar da hayaniya maras so. Lokacin da aka haɗa su tare da injinan CNC don mahimman abubuwan mating, kayan aikin EV da aka zuba jari sun cimma matakan NVH waɗanda ke bambanta samfuran EV masu ƙima.

Zane 'Yanci don Haɗin Abubuwan EV

Ofaya daga cikin fa'idodin mafi ƙarfi na simintin saka hannun jari don masana'antar EV shine 'yancin ƙira . Tsarin kakin zuma da ya ɓace yana ba injiniyoyi damar haɗa abubuwa da yawa zuwa simintin gyare-gyare guda ɗaya, kawar da mahaɗin haɗaɗɗiya, masu ɗaure, da yuwuwar hanyoyin ɗigo.

Misali, gidan mota na gargajiya na EV na iya ƙunsar sassa daban-daban na injuna guda biyar waɗanda aka kulle tare. Madaidaicin simintin saka hannun jari na iya haɗa flange mai hawa, jaket mai sanyaya, wurin zama, da shigar da kebul cikin sassa ɗaya. Wannan hanyar:

Tashoshin sanyaya na ciki suna bin ingantattun hanyoyin thermal, tsarin haƙarƙari na halitta wanda aka yi wahayi ta hanyar haɓakawa ta hanyar haɓakawa, da kaurin bango mai canzawa duka ana iya cimma su tare da ƙirar kakin zuma da aka buga na 3D - fasahar da Ningbo Ruican ya haɗa cikin tsarin aikin sa na EV.

Dorewa: Amfanin Tattalin Arzikin Da'ira na Casting

Kamar yadda masana'antar EV ta sanya kanta a matsayin madadin ɗorewa, ayyukan masana'antu a bayan abubuwan EV suna zuwa ƙarƙashin bincike. Simintin saka hannun jari yana ba da fa'idodi masu dorewa:

• Samar da siffa na kusa-net yana rage sharar kayan abu zuwa ƙasa da 10% (vs. 40-60% don machining daga billet)
• Aluminum sake yin amfani da shi - sama da kashi 90% na aluminium da aka zuba jari za a iya sake yin fa'ida a ƙarshen rayuwa tare da ƙarancin lalata dukiya.
• Ingantacciyar makamashi - murhun narke narke na zamani na zamani wanda aka yi amfani da shi wajen yin simintin saka hannun jari ya kai 85% ingantaccen makamashi da 60% don narkewar kofi na gargajiya
• Rage fitar da hayaki - sassa masu nauyi suna rage nauyin abin hawa, haɓaka kewayon EV kai tsaye da rage yawan kuzari a tsawon rayuwar abin hawa.

Amfanin Ningbo Ruican ga Masu kera EV

Ningbo Ruican ta zuba jari simintin kayan aiki ne manufa-gina ga madaidaicin bukatun na EV bangaren masana'antu. Ayyukanmu sun haɗa da:

• A356.2 aluminum simintin gyaran kafa tare da bango kauri daga 3.0mm, bokan zuwa IATF 16949
• 5-axis CNC machining don ɗaukar kujeru (H6 haƙuri), hatimi tsagi, da kuma hawa gammaye.
