Lapho amaqembu ezimboni edinga indawo yokusebenza engeke ibambene ngaphansi kokuhlukunyezwa kwansuku zonke—kodwa ingena emnyango ojwayelekile ngaphandle kwe-forklift— Ithebula lemeshi le-BRC ilokhu ibonakala ezindlini zokulala zamathuluzi, amaveni enkonzo yasensimini, namaseli okukhiqiza athambile kulo lonke elaseNyakatho Melika naseYurophu. Siyibonile isetshenziswa ezindaweni zokwakha lapho uthuli lukakhonkolo luvala amaslayidi ekhabetheni, kumalebhu e-R&D ezolimo lapho ugrisi noketshezi olusebenza ngamanzi kuwumkhuba, nangaphakathi kwamakamelo ahlanzekile abahlinzeki bezimoto be-Tier-1 lapho ukubekezelela ukucaba kungu-±0.3 mm ngaphezu kwamamitha angu-1.2. Akunabukhazikhazi. Ayisho ukuthi "ihlakaniphile." Kodwa ixazulula izinkinga ezintathu amabhentshi amaningi angazinaki: isisindo ngokumelene nokuqina, isikhathi sokuhlanganisa ngokumelene nobuqotho besakhiwo, kanye nokumelana nokugqwala ngokumelene nezindleko.
Kungani “I-Mesh” Ingeyona Inketho Yokuklama Nje—Inengqondo Ethwala Imithwalo
Amatafula amaningi ensimbi anesitembu asebenzisa iziqongo eziqinile noma amapuleti anezimbobo. Ithebula lemeshi le-BRC lisebenzisa igridi enemeshi eqinile, eshiselwe—insimbi engagqwali engu-6 mm ububanzi noma izintambo zensimbi ezigoqeke ngokubanda ezihlukaniswe ezindaweni ezingu-25 mm. Leyo geometry iletha okuthile amapuleti aqinile angakwazi: ukuqina okuguquguqukayo okusabalalisiwe ngo-42% wesisindo esincane. Ekuhlolweni komhlaba wangempela, iyunithi ye-BRC engu-1200 × 750 mm isekela umthwalo omaphakathi ongu-185 kg ngokuchezuka ngaphansi kuka-1.1 mm—ngenkathi inesisindo esingu-14.3 kg kuphela. Qhathanisa lokho nokunye okuqinile okuphezulu okuqhathanisekayo ekuchezukeni okungu-24.7 kg no-2.8 mm. Imeshi ayibuthakathaka; yakhelwe ukumelana ne-torsion *endizeni yonkana*, hhayi nje mpo. Kungakho ochwepheshe babika ukuthi uziro "ukugegetheka" lapho benyakazisa amahabhu amasondo angu-120 N·m ngaphezulu—futhi kungani amathuluzi okulinganisa azwela ukudlidliza ehlala ezinzile ngesikhathi sokusetha amahora amaningi.
Umhlangano Ofanelana Neshejuli Yakho, Hhayi Umugqa Wesikhathi Wemanuwali
“Kulula ukuhlanganisa” kusho izinto ezahlukene kubasebenzisi abahlukene. Kumhleli wokulungisa e-Wisconsin, kusho ukuthi zonke izingxenye zekhompuyutha zihlungwe kusengaphambili ngama-polybags anelebuli—hhayi amabholithi axegayo ku-ziplock eyodwa. Kumphathi wezokuthutha e-Rotterdam, kusho ukuthi awekho amathuluzi akhethekile adingekayo ngaphezu kokhiye we-hex ongu-5 mm (okufakiwe) nangaphansi kwamaminithi angu-8 ukuze kwakhiwe ngokugcwele. Uhlelo lwe-BRC lusebenzisa amantongomane athunjiwe, amajoyinti aziqondanisa nama-flange, namaphinikhodi okuthola acijile achofoza endaweni ngaphambi kokuqiniswa. Akukho ukucwayiza. Akukho ukulinganisa kwecala nephutha. Awekho ama-torque specs angaphezu kuka-8 N·m. Silandelele ukwakhiwa kwenkambu engama-37 emazweni amane: isilinganiso sezinga lempumelelo lokuqala lalingu-94%. U-6% osele? Konke kulandelelwa ekulahlekeni kwewasha eyodwa—hhayi ukungaqondani kahle noma imicu ehlutshiwe. Lokho kuthembeka kuvela kulawulo lwangaphakathi lwe-Botou Haijun Metal Products Co., Ltd. lokunyathela nokugoba kwangaphakathi: wonke ubakaki, umkhono womlenze, ne-cross-brace yakheka ekusetheni okukodwa ku-CNC hydraulic press, okuqeda ukukhukhuleka okukhulayo kokubekezelelana phakathi kwezingxenye ezincane.
Ukuqina Ongakwazi Ukukuqinisekisa—Hhayi Ukuthembisa Kuphela
Ukungasindi akusho ukuthi kuntekenteke—uma izinto zokwakha kanye nenqubo kulawula ikhophi yasenqolobaneni. Ithebula ngalinye lemeshi ye-BRC liqala ngensimbi egoqelwe ebandayo eqinisekisiwe (SPCC-SD, Q235B) noma engu-304 engenasici, elandelekayo emibikweni yokuhlolwa komshini. Ukwelashwa okungaphezulu akuyona into ecatshangwayo: I-electrophoretic coat (E-coat) ihlanganisa u-100% wemithungo ye-weld kanye nezimbobo zangaphakathi-ngokungafani nejazi lempushana, elishiya ama-microscopic voids ezindaweni ezithinteke ukushisa. Ukuhlolwa kwesifutho sikasawoti kuqinisekisa amahora angu-≥720 ukugqwala okumhlophe ezinhlobonhlobo zensimbi ye-carbon. Ezinguqulweni ezingenasici, i-mesh idlula i-ASTM A967 ngayinye, iqinisekiswe ukuhlolwa kwendawo ye-copper sulfate. Lokho abasebenzisi abakubonayo akulona ishidi elicacisiwe—yilokho izimbobo zamabhawodi zihlala zihlanzekile ngemva kweminyaka emibili yokusetshenziswa phansi kwesitolo, futhi izinyawo zemilenze azibonisi ukuqhekeka okuncane lapho zithintana khona nezitezi zikakhonkolo ezine-epoxy.
Imikhawulo Yangempela Yokuthunyelwa—Nendlela I-BRC Izixazulula Ngayo
Izindawo zokuhlala ezengeziwe e-Space-limited: Ubude obugoqiwe bungu-128 mm—bungena ngaphansi kwemishayo eminingi yokuqopha yephalethi. Imilenze iyahlukana ngaphandle kwamathuluzi futhi isidleke ngaphakathi kohlaka lwemeshi. Akukho ukubambelela okuqinile: Izinyawo zenjoloba ezihlanganisiwe ezimelene nokushelela (I-Shore A 60) zivimbela ukunyonyoba okusemaceleni ezindaweni ezitshekile—ngisho nokuthambeka okungu-8° ngesikhathi sokulungiswa kwemishini ephathwayo. Izidingo zokuhlanganisa ithuluzi: Izimbobo ezijwayelekile ezinobubanzi obungu-16 mm ezihlukaniswe kumagridi angu-50 mm zamukela ama-clamp ama-modular, ama-vise mounts, nezingalo ezikhanyisa ngaphandle kokubhoboza noma ama-adaptha. Ukuthobela imithetho: Ihlangabezana nezidingo ze-EN 10219-2 zemishini yezingxenye ezingenalutho ezisetshenziswa emilenzeni; Amandla e-mesh tensile ≥520 MPa nge-ISO 6892-1. I-Botou Haijun ayithumeli isitoko esijwayelekile. I-oda ngalinye letafula lemeshi le-BRC lihlanganisa ukuqinisekiswa kwesakhiwo esibuyekezwe yi-CAD, impendulo ye-DFM ezicini zokukhweza ngokwezifiso, nemibiko yokuhlola enobukhulu esayinwe onjiniyela be-QC—hhayi nje izitifiketi zenqwaba. Yileyo ndlela amakhasimende aphindayo e-Germany nase-Canada agcina ngayo ≤0.7% izilinganiso zokubuya kwenkambu kuwo wonke amayunithi angu-11,000+ athunyelwe kusukela ngo-2021.
I Ithebula lemeshi le-BRC uyaphumelela ngoba wenqaba ukwethembisa ngokweqile. Ngeke ingene esikhundleni sepuleti elingaphezulu legwadle lamalebhu e-metrology. Ngeke isekele imithwalo engashintshi engu-500 kg njengebhentshi elishiselwe i-I-beam. Kodwa lapho ukuhamba, isivinini sokusebenza, ukuzinza kobude besikhathi eside, kanye nempilo yesevisi ebikezelwayo kubaluleke ngaphezu kobukhulu bethiyori—iyaletha. Emaqenjini akhathele ukukhetha phakathi “kokukhanya kodwa okuntengantengayo” kanye “nokuqinile kodwa okunganyakazi,” lena indawo yokusebenza ekugcineni eyeka ukuphoqa ukuhwebelana. Yakhelwe lapho ubuchwepheshe bokwakha amakhaza buhlangabezana nemiphumela yomhlaba wangempela-futhi ihlolwe lapho ukubekezelelana kukalwa ngama-microns, hhayi izincwajana zokumaketha.
