Iyo amakipe yinganda akeneye ubuso bwakazi butazagerwaho no guhohoterwa buri munsi-nyamara bihuye numuryango usanzwe udafite forklift-the Imbonerahamwe ya BRC ikomeza kwigaragaza mubikoresho byububiko, amamodoka ya serivisi yo mu murima, hamwe ningirabuzimafatizo zikora ibinure muri Amerika ya Ruguru n'Uburayi. Twabonye ko yashyizwe ahakorerwa imirimo aho umukungugu wa beto ufunze kunyerera, muri laboratoire yubuhinzi R&D aho amavuta na hydraulic fluid bisanzwe, kandi imbere muri Tier-1 itanga amamodoka ibyumba bisukuye aho kwihanganira uburinganire bwa mm 0.3 mm hejuru ya metero 1.2. Ntabwo ari byiza. Ntabwo ivuga ko ari "umunyabwenge." Ariko ikemura ibibazo bitatu intebe zakazi zirengagiza: uburemere nuburemere, igihe cyo guterana nuburinganire bwimiterere, hamwe no kurwanya ruswa hamwe nigiciro.
Kuki "Mesh" Atari Guhitamo Igishushanyo-Ni Logic-Yikoreye Imizigo
Ameza yakazi menshi yashyizweho kashe akoresha hejuru cyangwa isahani isobekeranye. Imbonerahamwe ya meshi ya BRC ikoresha umurongo wa terefegitura usa neza, usanzwe usanzwe wa mm 6 z'umurambararo wa mm 6 cyangwa insinga z'icyuma zikonje zikonje kuri santimetero 25. Iyo geometrie itanga ikintu isahani ikomeye idashobora: gukwirakwiza flexural stiffness hamwe na 42% nkeya. Mu kwipimisha kwisi, ibice 1200 × 750 mm BRC bishyigikira umutwaro wa kg 185 hamwe no gutandukana munsi ya mm 1,1 - mugihe ipima kg 14.3. Gereranya ibyo nibindi bigereranywa-hejuru hejuru ya 24.7 kg na 2.8 mm gutandukana. Mesh ntabwo ifite intege nke; ni injeniyeri yo kurwanya torsion * hejuru yindege *, ntabwo ihagaritse gusa. Niyo mpamvu abatekinisiye bavuga zeru “wobble” mugihe batwitse hejuru ya 120 N · m yibiziga hejuru-nimpamvu ibikoresho bya kalibrasi byunvikana bikomeza guhagarara mugihe cyamasaha menshi.
Inteko ijyanye na gahunda yawe, ntabwo ari igihe cyagenwe
"Byoroshye-guteranya" bisobanura ibintu bitandukanye kubakoresha batandukanye. Kubashinzwe gutunganya muri Wisconsin, bivuze ko ibyuma byose byabanjirijwe gutondekanya muri polybags byanditseho - ntabwo bihindagurika muri ziplock imwe. Kubashinzwe ibikoresho muri Rotterdam, bivuze ko nta bikoresho byihariye bisabwa birenze urufunguzo rwa mm 5 (harimo) no munsi yiminota 8 kugirango byubake. Sisitemu ya BRC ikoresha utubuto twafashwe mpiri, guhuza-guhuza flange hamwe, hamwe na pine zerekana aho zikanda mbere yo gukomera. Nta shimming. Nta kigeragezo-n'ikosa kuringaniza. Nta muriro uri hejuru ya 8 N · m. Twakurikiranye imirima 37 yubatswe mubihugu bine: impuzandengo yambere yambere yatsinze yari 94%. Ibisigaye 6%? Byose byerekanwe kubura umwe wogeje - ntabwo ari uguhuza cyangwa kumutwe. Ukwo kwizerwa guturuka muri Botou Haijun Metal Products Co., Ltd. mu nzu yo guteramo kashe no kugonda: buri kantu kose, amaboko yamaguru, hamwe na cross-brace bikozwe muburyo bumwe kuri mashini ya hydraulic ya CNC, bikuraho ubworoherane bwo kwihanganira ibintu hagati yibice bito.
Kuramba Urashobora kugenzura - Ntabwo ari amasezerano gusa
Umucyo woroshye ntabwo bivuze ko woroshye-niba ibikoresho nibikorwa bigenzura inyuma. Buri mbonerahamwe ya mesh ya BRC itangirana nicyuma cyemewe gikonje (SPCC-SD, Q235B) cyangwa 304 idafite ingese, ishobora gukurikiranwa na raporo yikizamini. Kuvura hejuru ntabwo ari ugutekereza: gutwikira amashanyarazi (E-coat) bitwikiriye 100% byimyenda yo gusudira hamwe nu mwobo w'imbere-bitandukanye n'ikoti ry'ifu, risiga icyuho cya microscopique kuri zone yibasiwe n'ubushyuhe. Kwipimisha umunyu byemeza amasaha 72020 kugeza ingese yera kumyenda ya karubone isize. Kuri verisiyo idafite umwanda, mesh ikora passivation kuri ASTM A967, igenzurwa no gupima umuringa wa sulfate. Ibyo abakoresha babona ntabwo ari urupapuro rwihariye - ni uko umwobo wa bolt ukomeza kugira isuku nyuma yimyaka ibiri ukoreshwa mu igorofa, kandi ibirenge byamaguru byerekana ko nta gucamo mikoro aho bahurira na epoxy yubatswe hasi.
Inzitizi Zoherezwa Mubyukuri-Nuburyo BRC ibakemura
Umwanya uteganyirijwe umwanya: Uburebure bwikubye ni mm 128 - buhuye munsi ya pallet racking. Amaguru atandukana adafite ibikoresho nicyari imbere murwego rwa mesh. Nta byuma bihoraho: Ibirenge birwanya anti-kunyerera (Shore A 60) birinda kunyerera kuruhande ahantu hahanamye - ndetse no kuri 8 ° mugihe cyo gusana ibikoresho bigendanwa. Guhuza ibikoresho bikeneye: Ubusanzwe umurambararo wa mm 16 uri hagati ya mm 50 ya gride yemera clamp modular, vise mount, hamwe namaboko yo gucana nta gucukura cyangwa adapt. Kubahiriza amabwiriza: Yujuje EN 10219-2 ibikoresho byubukanishi kubice bikonje bikonje bikoreshwa mumaguru; mesh tensile imbaraga ≥520 MPa kuri ISO 6892-1. Botou Haijun ntabwo yohereza ububiko rusange. Buri mbonerahamwe ya BRC mesh ikubiyemo gahunda ya CAD yasuzumwe yemeza imiterere, ibitekerezo bya DFM kubiranga ibicuruzwa byabigenewe, na raporo yubugenzuzi bwashyizweho umukono naba injeniyeri ba QC - ntabwo ari ibyemezo byicyiciro gusa. Nuburyo gusubiramo abakiriya mubudage na Kanada bagumana ≤0.7% igipimo cyo kugaruka kumurima mubice 11,000+ byoherejwe kuva 2021.
Uwiteka Imbonerahamwe ya BRC aratsinda kuko yanze kurenza urugero. Ntabwo izasimbuza isahani ya granite ya laboratoire ya metero. Ntabwo izashyigikira kg 500 yimitwaro ihagaze nkintebe yo gusudira I-beam. Ariko aho kugenda, umuvuduko wo koherezwa, igihe kirekire cyo gutuza, hamwe nubuzima bwa serivisi buteganijwe kuruta ibintu byinshi-bitanga. Ku makipe arambiwe guhitamo hagati yumucyo ariko wobbly "na" bikomeye ariko bitimukanwa, "ubu ni bwo buryo bwakazi burangiza bugahagarika guhatira ibicuruzwa. Yubatswe aho ubuhanga bukora ubukonje buhura ningaruka zifatika-kandi bukageragezwa aho kwihanganira bipimirwa muri micron, ntabwo ari udutabo twamamaza.
