Iko Kushandiswa kweJekiseni Molding muMotokari Zvikamu Kugadzira
MuGermany, kuumba jekiseni ndeimwe yeanonyanya kushandiswa kugadzira mapurasitiki. Izvi ndizvo chaizvo sezvo ichipa mhinduro inoshanda yekugadzirwa kwakawanda kweyemhando yepamusoro jekiseni zvikamu zvemotokari kubva pahupamhi hwemapolymers. Muindasitiri yemotokari, uko kuenderana, kuchengetedzeka, uye hunhu hwakanyanya kukosha, mota yepurasitiki jekiseni kuumba ibasa rakakosha rekugadzira.
Kune akati wandei anozivikanwa anogadzira maindasitiri emotokari kubva kuGermany, anoshandira pamwe neDJmolding, kutenga zvinhu zvepurasitiki zvemotokari kubva kuDJmolding jekiseni rekugadzira masevhisi, anosanganisira fenders, grilles, bumpers, mapaneru emagonhi, njanji dzepasi, dzimba dzakareruka, nezvimwe.
KuDJmolding, isu tinopa inyanzvi jekiseni rekuumba masevhisi, kuendesa-akagadzirwa-akagadzirwa epurasitiki zvikamu zvemotokari kune vatengi mumotokari uye mamwe maindasitiri. Masevhisi edu anosanganisira thermoplastic jekiseni kuumba, pamusoro-kuumbwa, kuisa kuumba, uye kugadzira mold. Muchiitiko chekupedzisira, nyanzvi dzedu dzinoshanda nevatengi veGerman kugadzira emhando yepamusoro mold ye prototyping kana yakakura yekugadzira inomhanya.
DJmolding inoshandawo nemhando dzakasiyana dzemajekiseni epurasitiki, kusanganisira yakasimba, inodzivirira kupisa, uye yakasimba thermoplastics; inoshanduka, inokurumidza kuporesa thermoplastics; uye akasimba, epamusoro-tembiricha erabha mapurasitiki. Yedu nyanzvi dzemotokari majekiseni epurasitiki ekuumba masevhisi anogonesa vatengi vedu vemotokari kuwana emhando yepamusoro akaumbwa zvikamu zvemotokari zvinosangana nezvinodiwa zvekushandisa, kunyanya kune nyika dzine simba indasitiri yemotokari, senge Gemany, USA, Japan.
Kugadzira Zvikumbiro zveMotokari Injection Molding
Muchikamu chemotokari, kuumba jekiseni ndeimwe yenzira dzinonyanya kushandiswa nevagadziri kugadzira zvikamu zvepurasitiki. Nekudaro, zvingave zvakaoma kugadzira rondedzero yezvikamu zvepurasitiki mumotokari inogadzirwa uchishandisa jekiseni molding, saka isu tichatarisa mamwe makuru.
1. Zvikamu pasi-the-hood
Kwemakumi maviri emakore apfuura kana zvakadaro, akawanda epasi-the-hood zvikamu izvo vagadziri vaimbogadzirwa kubva kusimbi zvakashandurwa kuita epurasitiki. Kune aya maapplication, akasimba mapolymers akadai seABS, Nylon, uye PET akajairika. Nekudaro, vagadziri vava kugadzira zvikamu zvakaita semavhavha emusoro uye mapani emafuta vachishandisa jekiseni kuumba. Iyi nzira inopa huremu hwakaderera uye mari inofananidzwa nezvikamu zvesimbi.
2. Kunze Zvikamu
Jekiseni molding inzira yakasimbiswa yezvinhu zvakawanda zvekunze zvemotokari, zvinosanganisira mafenda, magrille, mabumpers, mapaneru emagonhi, njanji dzepasi, dzimba dzakareruka, nezvimwe. Splash guards muenzaniso wakanaka wekuratidza kusimba kwezvikamu zvakaumbwa jekiseni. Pamusoro pezvo, izvo zvinodzivirira mota kubva kumarara emumugwagwa uye kuderedza kuputika, zvinowanzogadzirwa kubva kurabha kana zvimwe zvinogara uye zvinochinjika zvinhu.
3. Zvikamu zvemukati
Vagadziri zvakare vanogadzira akawanda emotokari emukati zvikamu vachishandisa mota dzepurasitiki jekiseni kuumba. Zvinosanganisira zviridzwa zvemidziyo, zvemukati zvemukati, dashboard faceplates, mibato yemagonhi, magirovhosi, mavhavha emhepo, nezvimwe. Pamusoro pezvo, ivo vanoshandisawo jekiseni molding yekugadzira yekushongedza epurasitiki zvinhu.
Dzimwe nzira dzeInjection Molding dzeMutengo wakaderera weMotokari Prototypes
Muzviitiko zvakawanda, mapurasitiki akaumbwa anoshanda seimwe nzira kune simbi. Kare, vagadziri vanogadzira zvinhu zvakaita semabhureki, trunk lids, seatbelt modules, uye air-bag midziyo chete kubva kusimbi. Mazuva ano, kuumba jekiseni ndiyo yakasarudzika nzira yekugadzira yemapurasitiki aya.
Kune rimwe divi, vagadziri dzimwe nguva vanogona kutsiva zvikamu zvepurasitiki zvakaumbwa nezvikamu zvemotokari zvepurasitiki zvakadhindwa 3D. Izvi zvinonyanya kuitika mu prototyping, uko kusingade kusimba kwakanyanya kana kutsetseka kwepamusoro pekupedzisira. Mapurasitiki akawanda anoumbwa anogona kushanda seFDM 3D printer filaments kana seSLS 3D printer poda yenaironi. Imwe nyanzvi uye yakakwirira-temp 3D maprinta anogona zvakare kudhinda akasimbiswa macomposites epamusoro-simba zvikamu.
Kune imwechete-kure prototypes, kunyanya isiri-mechanicha zvikamu, 3D kudhinda kunogona kupa inodhura-inoshanda imwe nzira yekuumba. Nekuda kwekushaikwa kwemitengo yekushandisa, mitengo yekugadzira haina kukwira.
Mune zvimwe zviitiko, vagadziri vanogona kutoshandisa 3D kudhinda kune mashoma ekupedzisira-kushandisa emotokari zvikamu. Vanogona kushandisa SLM 3D kudhinda kugadzira fluid inobata zvikamu sevhavha (kwete kazhinji jekiseni rakaumbwa). Nekudaro, imwe sarudzo iri kushandisa SLS 3D kudhinda kugadzira zvikamu zvakaita semabumpers, trim, uye windbreaker, izvo dzimwe nguva zvinoumbwa jekiseni.
Vagadziri vanogona kushandisa yekuwedzera yekugadzira kune yakawedzera kuwanda yejekiseni auto zvikamu mune isiri kure-kure-remangwana. Izvi zvinogona kubva pamagonhi uye mapaneru emuviri (SLM) kune powertrain uye drivetrain zvikamu (EBM).
DJmolding yakanaka kwazvo pakugadzira jekiseni repurasitiki rezvikamu zvemotokari, kana iwe uchida kutanga purojekiti yekugadzira zvikamu zvemotokari, ndapota taura nesu, tichava nekambani yakanaka.
