Buri kintu cyose cyatsinzwe cya BIW gitangira inzira imwe - ntabwo ari impanuka, ariko hamwe no kudahuza neza mugihe cyambere cyo gufata. Twabibonye ku migabane itatu: guhinduranya 0,15 mm ya datum ihinduranya impande zombi itera kwihanganira guhuriza hamwe kuri sitasiyo esheshatu; isahani y'ifatizo isudira nyuma yamasaha 48 yo gukomeza gukora; pneumatike itakaza imbaraga kuri 32 ° C ibidukikije - hejuru yubushyuhe bwimpeshyi muri Chennai cyangwa Monterrey.
Impamvu BIW Igishushanyo mbonera ni moteri ituje yo gukora ibinyabiziga bikora neza
Ibikoresho bya BIW ntabwo ari ibyuma bifata impapuro gusa. Nubusobanuro bwumubiri bwa GD&T bugamije mubyukuri gusubiramo kinematike. Muri Botou Haijun Metal Products Co., Ltd., twubatse kandi twemeza ibikoresho birenga 1,270 BIW kuva 2016 - buri kimwe cyageragejwe ningutu munsi yumutwaro nyawo, ukwezi kwizuba, hamwe nigihe cyo kubungabunga. Amakuru yacu yerekana ko 68% byumurongo uteganijwe guhagarara mumaduka yumubiri wa Tier-1 ugaruka kumpamvu ziterwa nimpamvu zishingiye: imizi yimyenda irenga mm 0.08, gukomera kwibanze munsi ya 2,3 × 10⁵ N / mm, cyangwa kwangirika kwingufu kurenga 12% kurenza 10,000.
Ikibazo nyamukuru? Ibikoresho bigomba guhaza ibintu bine bidashobora kumvikana icyarimwe: gutuza kwa kinematike (nta kurenza urugero), kutagira aho babogamiye (ΔL ≤ 0,03 mm kuva kuri 20-40 ° C), igihe kirekire (≥ 500.000 cycle nta kwisubiramo), na abantu ba ergonomique (clamp actuation force ≤ 22 N, igihe cyizunguruka ≤ amasegonda 4.2). Wumvikane icyaricyo cyose - kandi imikorere irasenyuka.
Ibyemezo bitatu byukuri-byisi bishushanya bifata cyangwa bisenya imikorere ya BIW
1. Guhitamo ibikoresho ntabwo bijyanye n'imbaraga-ni kwibuka kwibuka. Twahagaritse gukoresha ibyuma bya A36 kubisahani fatizo muri 2020. Coefficient yayo yo kwagura ubushyuhe (12.0 × 10⁻⁶ / ° C) yateje umuvuduko muke mugihe ubushyuhe bwazamutse hagati. Uyu munsi, turerekana ASTM A572 Icyiciro cya 50 hamwe no kugabanya imihangayiko nyuma yo gutunganywa-kandi iyo bihujwe no gusaza amasaha 72. Kubantu basobanutse neza, dukoresha 17-4 PH ibyuma bitagira umwanda, bikoreshwa nubushyuhe kuri H900 (485 HB), tugera kumurongo uhamye muri ± 1.3 HRc mumyaka 3 yo gukoresha umurima.
2. Ingamba zifatika zigena irekurwa ryigice - ntabwo ari imbaraga gusa. Indwara ya pneumatike irananirana mugihe umwuka wifunitse urimo> 0.5 ppm amavuta cyangwa ikime kirenze 3 ° C. Igisubizo cyacu: guhuza inzira ebyiri. Clamps yibanze ikoresha silinderi ISO 15552 hamwe na sensor yumwanya uhuriweho; icyiciro cya kabiri "cyoroheje-gukoraho" koresha urethane yuzuye amasoko (Shore A 70) ikanda mm 1,2 mbere yo guhura - ikuraho amenyo hejuru yicyiciro cya A. Ubuzima bwikizamini busimbuka kuva 180.000 bugera kuri 620.000.
3. Imiterere ya Datum igomba kwerekana inteko ikurikirana - ntabwo ari moderi ya CAD. OEM imwe yu Burayi yashimangiye kuri 3-2-1 kuri buri sitasiyo. Twarayubatse. Noneho reba igice gikwiye kwangirika nyuma ya Sitasiyo 4. Impamvu? Urutonde rwabo rwose rwo gusudira rwapakiye igice mu buryo butemewe, bitera ihindagurika rya elastique ridashobora kwishyurwa. Twongeye gushushanya hamwe na datum ikurikirana: Sitasiyo 1 ifunga hasi pan flanges; Sitasiyo ya 3 yongeramo inkunga ya sill * gusa nyuma ya * rocker panel gusudira; Sitasiyo ya 6 itangiza ibisenge bya gari ya moshi - ntabwo mbere. Umusaruro wambere wambere wavuye kuri 71% ugera kuri 99.4%.
Ibyo ba injeniyeri benshi birengagiza (nuburyo bwo kubikosora)
Bamwe bavuga ko igishushanyo mbonera ari imashini gusa - kubara imbaraga no guhitamo ibikoresho. Ariko amakuru yacu yo murwego aravuguruza ibyo. Muri 41% byimikorere yanze, inenge ntiyari yubatswe. Byari abantu: abashoramari barengana aho umutekano uhurira kubera ko ibyuma bifata amashanyarazi byasabye 32 N yingufu, cyangwa abatekinisiye basibye kalibrasi kubera ko iperereza rya CMM ryasabye gusenywa burundu.
Turabikosora hamwe na disipuline yashushanyije:
Gushushanya imbaraga. Kubungabunga-geometrie yambere: Ibifunga byose bicara muri 120 ° arc yabakozi bagera; intego ya kalibrasi ikozwe muburyo butaziguye - ntabwo byongeweho nkibisahani Ubushuhe: Ibyapa byibanze byashyizwe kumashanyarazi ya elastomeric (durometero 55 Inkombe A) hamwe na 0.8 mm ihindagurika - guhagarika ihererekanyabubasha ryamaduka munsi ya 15 Hz Ibi ntabwo ari amahame. Urugi ruheruka gukwega imbere imbere muri gahunda ya EV yo muri Amerika y'Amajyaruguru yakoresheje 14,200 idahagarara mbere yo kuyitaho bwa mbere - irenga intego ya OEM kuri 310%.
Kuva Gushushanya Kuri Kohereza: Porotokole yo Kwemeza Haijun
Ntabwo twohereza ibikoresho-twohereza ubushobozi bwo kugenzura neza. Buri BIW igizwe n'ibice bine byo kwemeza:
Kwigana kwa DFM. Kwipimisha prototype yumubiri. Amaduka-yumye. Inyandiko zishobora gukurikiranwa: Raporo yanyuma ikubiyemo CMM yogusuzugura, gusoma ibipimo byerekana, hamwe no gufata neza inyandikorugero - byose byatanzwe mugihe cyamasaha 72 uhereye igihe winjiye Botou Haijun Metal Products Co., Ltd. ikorera mu mujyi wa Botou-umutima w’ibinyabuzima bikora Ubukonje-Ubushinwa-aho bidasobanutse neza. Nibyingenzi. Iyo ukeneye a biw fixture ifata ukuri mubihe, ibihe, hamwe nabatanga impinduka, tangirana nububiko buke - ntabwo ari ibyuma gusa.
