Nkhani Za Kampani

Mould ndiye zida zoyambira zamagalimoto zamagalimoto. Zoposa 90% za magawo ndi zida zopangira magalimoto ziyenera kupangidwa ndi nkhungu. Malinga ndi a Luo Baihui, katswiri wa nkhungu, pafupifupi nkhungu 1,500 zimafunika kupanga galimoto wamba, yomwe imagwiritsidwa ntchito kuposa 1,000. Popanga zitsanzo zatsopano, 90% ya ntchito ikuchitika kuzungulira kusintha kwa thupi. Pafupifupi 60% ya mtengo wa chitukuko cha mitundu yatsopano imagwiritsidwa ntchito popanga matupi ndi masitampu ndi zida. Pafupifupi 40% ya mtengo wopangira magalimoto ndi mtengo wa ziwalo zopondaponda ndi kusonkhana.
Pachitukuko cha makampani a nkhungu zamagalimoto kunyumba ndi kunja, ukadaulo wa nkhungu wawonetsa njira zotsatirazi zachitukuko.
1. Kayeseleledwe ka masitampu (CAE) ndiwodziwika kwambiri
M'zaka zaposachedwa, ndikukula kofulumira kwa mapulogalamu apakompyuta ndi zida, ukadaulo woyeserera (CAE) wa njira yopangira masitampu akugwira ntchito yofunika kwambiri. M'mayiko otukuka monga United States, Japan, ndi Germany, teknoloji ya CAE yakhala yofunika kwambiri pakupanga nkhungu ndi kupanga. Amagwiritsidwa ntchito kwambiri kulosera zakupanga zolakwika, kukhathamiritsa njira yosindikizira ndi mawonekedwe a nkhungu, kukonza kudalirika kwa mapangidwe a nkhungu, ndikuchepetsa nthawi yoyeserera nkhungu. Makampani ambiri opangira nkhungu zamagalimoto apanyumba nawonso apita patsogolo kwambiri pakugwiritsa ntchito CAE ndipo apeza zotsatira zabwino. Kugwiritsa ntchito ukadaulo wa CAE kumatha kupulumutsa kwambiri mtengo wa nkhungu zoyeserera ndikufupikitsa njira yachitukuko ya nkhungu zopondaponda, zomwe zakhala njira yofunika kwambiri yotsimikizira mtundu wa nkhungu. Ukadaulo wa CAE ukusintha pang'onopang'ono kapangidwe ka nkhungu kuchoka pakupanga kwamphamvu kupita ku kapangidwe kasayansi.
2. Malo a nkhungu 3D mapangidwe amaphatikizidwa
Mapangidwe atatu a nkhungu ndi gawo lofunika kwambiri la teknoloji ya nkhungu ya digito ndi maziko ophatikizira mapangidwe a nkhungu, kupanga ndi kufufuza. Makampani monga Toyota ndi General Motors a ku United States azindikira mapangidwe atatu a nkhungu ndipo apeza zotsatira zabwino zogwiritsira ntchito. Njira zina zomwe zimatengedwa pamapangidwe a 3D mold kunja ndizoyenera kuzifotokoza. Kuwonjezera pa kukhala okonzeka kukwaniritsidwa kwa kupanga zophatikizika, mapangidwe atatu a nkhungu ali ndi ubwino wina kuti ndi wosavuta kuyang'ana zosokoneza ndipo akhoza kuchita kafukufuku wosokoneza kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, komwe kumathetsa vuto pamapangidwe amitundu iwiri.
Chachitatu, ukadaulo wa nkhungu wa digito wakhala njira yayikulu
M'zaka zaposachedwa, chitukuko chofulumira cha teknoloji ya nkhungu ya digito ndi njira yabwino yothetsera mavuto ambiri omwe amakumana nawo pakupanga nkhungu zamagalimoto. Zomwe zimatchedwa ukadaulo wa nkhungu wa digito ndikugwiritsa ntchito ukadaulo wapakompyuta kapena ukadaulo wothandizidwa ndi makompyuta (CAX) popanga nkhungu ndi kupanga. Kufotokozera mwachidule zomwe zachitika bwino m'makampani opangira magalimoto akunyumba ndi akunja pakugwiritsa ntchito ukadaulo wothandizidwa ndi makompyuta, ukadaulo wamagalimoto a digito umaphatikizanso izi: ① Design for manufacturability (DFM), ndiye kuti, kupanga kumaganiziridwa ndikuwunikidwa pakupanga kuti zitsimikizire kuti zikuyenda bwino. za ndondomekoyi. ②Tekinoloje yothandizira pakupanga mbiri ya nkhungu, pangani ukadaulo wanzeru wamapangidwe. ③CAE imathandizira pakuwunika ndi kupondaponda pamapangidwe, kulosera ndi kuthetsa zolakwika zomwe zingatheke ndikupanga zovuta. ④ Bwezerani mawonekedwe amitundu iwiri ndi mawonekedwe atatu-dimensional nkhungu. ⑤Kupanga nkhungu kumatengera luso la CAPP, CAM ndi CAT. ⑥ Motsogozedwa ndiukadaulo wa digito, thana ndi kuthana ndi mavuto omwe amabwera poyesa nkhungu ndi kupanga masitampu.

Chachinayi, kukula mofulumira nkhungu processing zochita zokha
Ukadaulo waukadaulo waukadaulo ndi zida ndi maziko ofunikira pakuwongolera zokolola ndikuwonetsetsa kuti zinthu zili bwino. Si zachilendo kuti makampani apamwamba a nkhungu zamagalimoto azikhala ndi zida zamakina a CNC okhala ndi ma worktable apawiri, osinthira zida zodziwikiratu (ATC), makina owongolera ma photoelectric opangira okha, komanso makina oyezera ntchito pa intaneti. Kuwongolera manambala kumapangidwa kuchokera kuzinthu zosavuta zopangira mbiri mpaka kukonzanso kwathunthu kwambiri ndi mawonekedwe apamapangidwe, kuchokera kuzinthu zapakatikati ndi zotsika-liwiro kupita kuzinthu zothamanga kwambiri, ndipo kukula kwaukadaulo wopangira makina kumathamanga kwambiri.
5. Ukadaulo wokwera kwambiri wachitsulo chopondaponda ndi njira yamtsogolo yachitukuko
Chitsulo champhamvu kwambiri chimakhala ndi mawonekedwe abwino kwambiri potengera kuchuluka kwa zokolola, mawonekedwe owumitsa, mphamvu yogawa, komanso kuyamwa kwamphamvu kugundana, komanso kuchuluka kwa magalimoto kumapitilira kukula. Pakalipano, zitsulo zamphamvu kwambiri zomwe zimagwiritsidwa ntchito pazitsulo zamagalimoto zimaphatikizapo zitsulo zowumitsa utoto (BH zitsulo), zitsulo zapawiri-gawo (DP zitsulo), ndi kusintha kwa gawo kumapangitsa pulasitiki (TRIP steel). Bungwe la International Ultra Light Body Project (ULSAB) likulosera kuti 97% ya galimoto yopita patsogolo (ULSAB-AVC) yomwe inakhazikitsidwa mu 2010 idzakhala chitsulo champhamvu kwambiri. Chigawo cha zitsulo zapamwamba zamphamvu kwambiri m'zinthu zamagalimoto zidzapitirira 60%, ndipo magawo awiri Gawo lazitsulo lidzawerengera 74% ya mbale zazitsulo zamagalimoto. Zitsulo zofewa zofewa zomwe zimagwiritsidwa ntchito makamaka muzitsulo za IF zidzakhala zolimba kwambiri zazitsulo zazitsulo, ndipo zitsulo zotsika kwambiri zotsika kwambiri zidzakhala zitsulo zapawiri-gawo ndi ultra-high-strength zitsulo. Pakadali pano, kugwiritsa ntchito mbale zachitsulo zamphamvu kwambiri pamagalimoto apanyumba kumakhala kocheperako pamapangidwe ndi matabwa, ndipo kulimba kwazinthu zomwe zimagwiritsidwa ntchito nthawi zambiri kumakhala pansi pa 500MPa. Choncho, mwamsanga kudziwa masitampu luso mbale mkulu-mphamvu zitsulo ndi vuto lofunika kuthetsedwa mwamsanga mu dziko langa nkhungu makampani galimoto.
6. Zatsopano za nkhungu zidzakhazikitsidwa pakapita nthawi
Ndi chitukuko champhamvu kwambiri komanso makina opangira masitampu agalimoto, kugwiritsa ntchito kufa kwapang'onopang'ono popanga zida zopondaponda pamagalimoto kudzakhala kokulirapo. Ziwalo zopondera zovuta, makamaka zing'onozing'ono ndi zazing'onoting'onoting'ono zomwe zimafuna nkhonya zingapo zimafa malinga ndi chikhalidwe, zimapangika kwambiri ndi kufa kwapang'onopang'ono. Progressive die ndi mtundu wa zinthu zopangidwa ndi nkhungu zapamwamba kwambiri, zomwe zimakhala zovuta mwaukadaulo, zimafunikira kulondola kwambiri, ndipo zimakhala ndi nthawi yayitali yopanga. Kufa kopitilira muyeso kopitilira muyeso kudzakhala imodzi mwazinthu zofunika kwambiri nkhungu mdziko langa.
Zisanu ndi ziwiri, zida za nkhungu ndiukadaulo wamankhwala apamwamba zidzagwiritsidwanso ntchito
Ubwino ndi magwiridwe antchito a nkhungu ndizofunikira zomwe zimakhudza mtundu wa nkhungu, moyo ndi mtengo wake. M'zaka zaposachedwapa, kuwonjezera pa kuyambika mosalekeza zosiyanasiyana toughness mkulu ndi mkulu kuvala kukana ozizira ntchito kufa zitsulo, moto kuzimitsa ozizira ntchito kufa zitsulo, ndi ufa zitsulo ozizira ntchito kufa zitsulo kufa zitsulo, ndi kopindulitsa kugwiritsa ntchito zipangizo kuponyedwa chitsulo chachikulu. ndipo masitampu apakati amafera kunja. Kuda nkhawa ndi chitukuko. Chitsulo cha Nodular cast chili ndi kulimba kwabwino komanso kukana kuvala, kuwotcherera kwake, kugwira ntchito, kuuma kwapamtunda kulinso kwabwino, ndipo mtengo wake ndi wotsika kuposa chitsulo cha alloy cast, motero chimagwiritsidwa ntchito kwambiri popondaponda pamagalimoto.
8. Kasamalidwe ka sayansi ndi chidziwitso ndi njira yachitukuko yamakampani a nkhungu
