Magawo Otsika Ochepa: Chifukwa Chake Kuyika kwa Investment Ndikoyenera pa Prototyping ndi Kupanga Kwamagulu Ang'onoang'ono

Thamangani masamu pa bulaketi yongoyerekeza ya 1.2 kg pa zidutswa 200 pachaka:

• CNC kuchokera mbale: ~ 85% ya zinthu zimakhala tchipisi; maola angapo mphero pa gawo; mtengo wagawo umakhala wokwera mpaka kalekale.
• Kuponyera mchenga: zida zotsika mtengo koma ± 1.5 mm+ kulolerana, malo osawoneka bwino, ndi makina achiwiri pa nkhope iliyonse yogwira ntchito.
• Die casting: Zida zokha zimaposa ndalama zonse zomwe zimagwiritsidwa ntchito pachaka.
• Kuyika ndalama: zida zolimbitsa thupi, kulondola kwa CT5-6, nkhope zambiri zomwe zimagwiritsidwa ntchito ngati-cast.

Pa zidutswa 200, zida zopangira ndalama zimawonongeka mwachangu, ndipo kuponya kulikonse pambuyo pake kumawononga ndalama zochepa poyerekeza ndi zomwe zimapangidwira. Crossover motsutsana ndi CNC-from-solid nthawi zambiri imagwera pakati pa zidutswa 20 ndi 100 kutengera ndi geometry - kutanthauza mbali zambiri zamakhalidwe, ngakhale maoda ang'onoang'ono ndiotsika mtengo ngati ma castings.

Kuthamanga kwa Prototype Popanda Prototype Compromise

Makonzedwe a chitukuko cha zinthu amalanga nthawi yotsogolera zida. Nzeru zachizoloŵezi zimati ma prototypes ayenera kupangidwa ndi makina chifukwa sizitengera zida - koma machitidwe osindikizira a 3D athetsa malingaliro amenewo.

Ndi QuickCast / castable resin mapatani , mayendedwe oponyera ntchito tsopano akuwoneka motere: CAD chitsanzo chatsirizidwa Lolemba; mapepala osindikizidwa usiku; zipolopolo zomangidwa, kuponyedwa ndi kuponyedwa mkati mwa sabata; zigawo zoperekedwa mu alloy, mu geometry yomaliza, masiku 10-14 kuchokera pakujambula. Yerekezerani izi ndi kukonza gawo la 5-axis (lomwe lingakhale lachangu pachidutswa chimodzi koma osafikira 20) kapena kudikirira masabata 6-10 kuti agwiritse ntchito wamba.

Ubwino waukadaulo ndi wocheperako kuposa liwiro: ma prototype castings ndi masewera enieni. Amanyamula microstructure yeniyeni ya alloy, kusintha kwa gawo lenileni, ndi malo enieni omwe amaponyedwa pakupanga. Mukatsimikizira kapangidwe kazinthu zosindikizidwa, mumatsimikizira njira yopangira nthawi yomweyo - osati kungoyerekeza komwe kungachite mosiyana ikangoponyedwa motsatizana. Zosintha zamapangidwe zomwe zidapezeka pamiyezo yamtengo wapatali nthawi yaukadaulo; kukonzanso komweku komwe kunapezeka pambuyo poti zida zopangira zidadulidwa zimawononga chida chatsopano.

Ufulu Wopanga Umene Ma Volume Ochepa Amagwiritsa Ntchito Bwino

Kupanga kwamphamvu kwambiri kumalanga zovuta za geometric chifukwa zovuta zimakhala ndi zida zodula. Investment kuponyera mphoto izo, chifukwa "chida" ndi sera chitsanzo - ndi zovuta mu chitsanzo pafupifupi kwaulere.

Izi ndizofunikira kwambiri pa voliyumu yotsika, pomwe zigawo zimakonda kukhala:

• Zosintha zolowa m'malo mwa zigawo sizinasungidwenso - nthawi zambiri zopanga zovuta zomwe sizinapangidwe kuti zipangidwe
• Kuphatikizika kwa ma welds amitundu yambiri kukhala ma castings amodzi (bulaketi, ma gussets atatu, ndi zoyikapo ziwiri zimakhala gawo limodzi - kuchotsa kuwunika kwa weld ndi kulephera)
• Mapangidwe oyendetsedwa ndi magwiridwe antchito - mayendedwe amkati, nthiti zopindika, zowoneka bwino zokongoletsedwa kuti zikhale zowuma mpaka kulemera zomwe palibe njira yochotsera yomwe ingabweretse mwachuma

Zochulukira zikakhala zazing'ono, kukonzanso kwa kuponyera ndikosavuta kulungamitsa: zida ndi zocheperako, geometry ilibe malire ndi ma ngodya kapena mizere yogawa, ndipo kuponyera kumodzi kumalowetsa msonkhano. Nthawi zonse timasintha zinthu zopangidwa ndi welded zomangira zida kukhala zotsika mtengo komanso zamphamvu kuposa zowotcherera zomwe zimasintha.

Zofunikira Zapamwamba Musapumule Pakuchepa Kwambiri - Nafenso sitipumula

Lingaliro lanthawi zonse ndilakuti ogulitsa ma voliyumu ochepa amagwira ntchito pamiyezo yotsika. Pachilichonse chokhudza kukakamiza, kukweza, kapena katundu wa drivetrain, kulingalira kumeneko ndi koopsa. Magulu ang'onoang'ono amafunikirabe:

• EN 10204
• Chitsimikizo cha Dimensional - CMM idayang'ana zolemba zoyamba motsutsana ndi zojambulazo, ndi macheke otengera ma geji pamndandanda
• Kuwongolera zolakwika - mtundu womwewo wa chipolopolo, kutsanulira chilango, ndi NDE (MT/UT/RT) yogwiritsidwa ntchito pazidutswa 50 ngati chidutswa cha 50,000
• Zolemba zamachitidwe - pamapulogalamu apagalimoto ndi apamsewu, zolemba zamtundu wa PPAP ngakhale pamavoliyumu opanga mlatho

Iyi ndi njira yosankha yomwe ogula akuyenera kufufuza: funsani omwe akuyembekezeka kukhala otsika kwambiri momwe amayendetsera bwino pamadongosolo a magawo 30. Wothandizira amayankha ndi machitidwe omwewo omwe amagwiritsa ntchito popanga ma serial - chifukwa makinawo amatsika, sazimitsa. Monga fakitale yovomerezeka ya IATF 16949, timayendetsa dongosolo limodzi labwino pakukula kulikonse; satifiketiyo sadziwa kukula kwake.

Gulu Laling'ono mpaka Seri: Mlatho Wopanda Gap

Makasitomala athu ambiri amayamba ang'onoang'ono - mawonekedwe a 10, mlatho wa 200 pomwe ogulitsa apanyumba amangoyenda - ndikukula kukhala opanga ma serial. Ubwino wa Investment cast pano ndi kupitiliza: kugwiritsa ntchito njira zomwezo, kachitidwe kachitidwe, ndi masikelo a pulani kuyambira pa nkhani yoyamba mpaka ma voliyumu apachaka mu makumi masauzande. Palibe chomwe chimatayidwa pamene voliyumu ikuwonjezeka; palibe yachiwiri tooling ndalama chofunika; ndi ndondomeko deta anagwidwa pa voliyumu otsika (shrinkage chipukuta misozi, kuponyera zokolola, kuthekera pa miyeso yovuta) amanyamula mwachindunji kupanga mndandanda.

Yerekezerani izi ndi msampha wanthawi zonse: kujambula ndi makina, kenako ndikuzindikira kuti kapangidwe kake kamakhala kosasunthika - mafupi, makoma owonda kwambiri, magawo omwe sangathe kudyetsa - kukakamiza kukonzanso ndendende nthawi yomwe ndandandayo ili yolimba kwambiri. Kukonzekera kojambula kuchokera ku prototype yoyamba kumachotsa phirilo.

Pamene Voliyumu Yotsika Simakondera Kuponya Ndalama

Uinjiniya wowona mtima umatanthauza kudziwa malire. Kuyika ndalama ndi njira yolakwika pamene:

• Mufunika magawo 1-3 a geometry yosavuta - kukonza kuchokera ku bar kapena mbale kumapambana pa liwiro
• Gawoli ndi lalikulu kwambiri (kupitirira pafupifupi 100-150 kg kapena envulopu yoopsa) - kupanga mchenga kapena kupanga
• Kulekerera ndi IT6 / IT7 pamalo ambiri - zomwe zili pamakina zimachotsa mwayi woponya
• Zigawo za khoma zimagwera pansi pa ~ 2.5-3 mm pa kukula kwa gawo lonse - malire a kutayika akugwiritsidwa ntchito

Woyambitsa wabwino amakuuzani izi mu gawo la mawu. Tifunseni, ndipo mupeza yankho lolunjika - kuphatikiza "makina" pomwe ndizotsika mtengo kwenikweni kwa inu.

Pansi Pansi

Zigawo zotsika kwambiri zimakhala m'malo omwe zida zachuma, zofunikira zolondola, komanso nthawi zotsogola zimakangana. Kuyika ndalama kumathetsa mkanganowo: zida zochepetsetsa, kulondola kwapafupipafupi pamakina opangira uinjiniya, liwiro lachiwonetsero kudzera pamapani osindikizidwa, ndi dongosolo labwino lomwe limayambira pa zidutswa 10 mpaka 100,000 osasintha. Kwa omanganso, omanga makina, ndi ma OEM omwe amalumikizana kuti apange, si njira yonyengerera - ndiyolondola.

Ningbo Ruican amapanga zopangira ndalama zotsika mpaka zapakatikati mu chitsulo cha kaboni, chitsulo cha aloyi, chitsulo chosapanga dzimbiri, ndi chitsulo cha ductile, chokhala ndi makina amkati a CNC, kasamalidwe kabwino ka IATF 16949, ndi mawonekedwe osindikizidwa omwe amapezeka. Titumizireni zojambula zanu ndi kuchuluka kwa zomwe mukufuna - tidzatchula ndondomeko yomwe ikugwirizanadi, ndi voliyumu yomwe mukufuna.
