Xa amaqela amashishini efuna indawo yokusebenza engayi kubambisana phantsi kokuxhatshazwa kwemihla ngemihla-kodwa ingena kumnyango oqhelekileyo ngaphandle kweforklift-i Itafile ye-BRC yemesh ihlala ibonakala kwiibhedi zezixhobo, iiveni zenkonzo yasentsimini, kunye neeseli zokuvelisa ezibhityileyo kuMntla Merika naseYurophu. Siyibonile ibekwa kwiindawo zokwakha apho uthuli lwekhonkrithi luvala izilayidi zedrowa, kwiilebhu ze-R&D zolimo apho igrisi kunye nolwelo olwenziwa ngolwelo olusebenza ngoxinzelelo lwendalo luyisiqhelo, kwaye ngaphakathi kweTier-1 amagumbi acocekileyo omthengisi wemoto apho ukunyamezelana okucaba yi-± 0.3 mm ngaphezulu kwe-1.2 yeemitha. Ayinabukhazikhazi. Ayithethi ukuba "ihlakaniphile." Kodwa isombulula iingxaki ezintathu uninzi lweebhentshi zokusebenza azihoyi: ubunzima ngokuchasene nobungqongqo, ixesha lendibano ngokuchasene nemfezeko yolwakhiwo, kunye nokumelana nomhlwa ngokuchasene neendleko.
Kutheni “uMesh” ingelulo nje uKhetho loYilo-Yingqiqo ethwele umthwalo
Uninzi lweetafile zentsimbi ezinesitampu zisebenzisa imiphezulu eqinileyo okanye iipleyiti ezinemingxuma. Itheyibhile yemesh ye-BRC isebenzisa igridi yocingo olunameva oludityanisiweyo kanye oludityanisiweyo—oluqhelekile ukuba yi-6 mm ubukhulu bentsimbi engatyiwayo okanye iingcingo zentsimbi eziqengqelekisiweyo eziqelelaniswe kumaziko angama-25 mm. Loo geometry ihambisa into eqinileyo iipleyiti ayikwazi: ukusabalalisa ukuqina kwe-flexural kunye ne-42% ubunzima obungaphantsi. Kuvavanyo lwehlabathi langempela, iyunithi ye-BRC ye-1200 × 750 mm isekela i-185 kg yomthwalo ophakathi ngokuphambuka phantsi kwe-1.1 mm-ngelixa i-14.3 kg kuphela. Thelekisa oko kunye nenye indlela enokuthelekiseka esomeleleyo-phezulu kwi-24.7 kg kunye ne-2.8 mm yokuphambuka. Umnatha awukho buthathaka; yenzelwe ukuxhathisa ukushukuma *kwinqwelomoya*, hayi ngokuthe nkqo. Yiyo loo nto amagcisa axela "i-zero" xa i-torquing 120 N·m hubs yamavili kumphezulu-kwaye kutheni izixhobo zokulinganisa i-vibration-sensitive calibration zihlala zizinzile ngexesha lokuseta iiyure ezininzi.
INdibano Ehambelana neShedyuli Yakho, hayi iXesha leManuwali
“Kulula ukuhlanganisa” kuthetha izinto ezahlukeneyo kubasebenzisi abohlukeneyo. Kumcwangcisi wokulondolozwa kwe-Wisconsin, kuthetha ukuba nazo zonke izixhobo ze-hardware zihlelwe kwangaphambili kwiipolybags ezibhaliweyo-kungekhona iibholiti ezikhululekileyo kwi-ziplock enye. Kumphathi wezothutho eRotterdam, kuthetha ukuba akukho zixhobo zikhethekileyo ezifunekayo ngaphaya kweqhosha le-5 mm hex (elibandakanyiweyo) nangaphantsi kwemizuzu eyi-8 yokwakha ngokupheleleyo. Inkqubo ye-BRC isebenzisa amantongomane athinjiweyo, i-self-aligning flange joints, kunye nezikhonkwane zendawo ezicofayo ezicofa endaweni ngaphambi kokuba ziqiniswe. Akukho shimming. Akukho mgangatho wokuzama kunye nempazamo. Akukho nkcazo yetorque ngaphezulu kwe-8 N · m. Silandelele ukwakhiwa kwentsimi engama-37 kumazwe amane: umndilili wempumelelo yexesha lokuqala ibiyi-94%. I-6% eseleyo? Zonke zilandwa kwiwasha enye elahlekileyo-hayi ukungahambi kakuhle okanye imisonto ekhutshiweyo. Oko kuthembeka kuvela kwi-Botou Haijun Metal Products Co., i-Ltd. ye-in-house stamping kunye nolawulo lokugoba: isibiyeli ngasinye, umkhono womlenze, kunye ne-cross-brace yenziwa kwisethingi enye kwi-CNC hydraulic presses, ukuphelisa ukunyamezelwa kokunyamezela phakathi kwezinto ezincinci.
Ukuqina Onako Ukukuqinisekisa—Akukokuba Uthembise nje
Ubunzima abuthethi ukuba buthathaka-ukuba izinto kunye nenkqubo zilawula ukuyibuyisela. Yonke itafile ye-BRC ye-mesh iqala ngentsimbi eqinisekisiweyo epholileyo (SPCC-SD, Q235B) okanye i-304 engenasici, elandelekayo kwiingxelo zovavanyo lokusila. Ukunyangwa kwendawo akuyonto yokucinga emva koko: i-electrophoretic coat (E-coat) igubungela i-100% ye-weld seams kunye ne-internal cavities-ngokungafaniyo ne-powder coat, eshiya i-microscopic voids kwiindawo ezichaphazelekayo ukushisa. Uvavanyo lwesitshizi setyuwa luqinisekisa ≥720 iiyure ukuya kumhlwa omhlophe kwiintlobo ezahlukeneyo zentsimbi yekhabhoni. Kwiinguqulelo ezingenastainless, i-mesh idlula kwi-ASTM A967, iqinisekiswe ngovavanyo lwamabala e-copper sulfate. Into ebonwa ngabasebenzisi ayilo ishidi le-specpec-yiyokuba imingxuma yebholithi ihlala icocekile emva kweminyaka emibini yokusetyenziswa komgangatho wevenkile, kwaye iinyawo zomlenze azibonisi ukuqhekeka kancinci apho zinxibelelana nemigangatho yekhonkrithi egqunywe nge-epoxy.
Izithintelo zoKwenyani zokusasazwa-Kwaye nendlela iBRC ezisombulula ngayo
Iindawo zokubonisa ezinesithuba: Ubude obusongekileyo yi-128 mm-ingena phantsi kweepali ezininzi zeerakhi. Imilenze iyahlukana ngaphandle kwezixhobo kunye nendlwane ngaphakathi kwesakhelo se-mesh. Akukho iankile esisigxina: Iinyawo ezidityanisiweyo zerabha ezichasene ne-slip (i-Shore A 60) zithintela ukukhahlela ngasecaleni kwiindawo ezithambekileyo-nangona kwi-8 ° incline ngexesha lokulungiswa kwezixhobo ezihambayo. Iimfuno zokudityaniswa kwesixhobo: Imingxunya esemgangathweni eyi-16 mm yobukhulu ebekwe kwi-50 mm yegridi yamkele i-clamp yemodyuli, ii-vise mounts, kunye neengalo ezikhanyisayo ngaphandle kokubhola okanye iadaptha. Ukuthobela imigaqo: Idibana ne-EN 10219-2 iimfuno zepropathi zoomatshini kumacandelo angaphakathi abandayo asetyenziswa emilenzeni; i-mesh tensile amandla ≥520 MPa ngokwe-ISO 6892-1. I-Botou Haijun ayithumeli isitokhwe segeneric. I-odolo yetafile yemesh ye-BRC nganye iquka uqinisekiso lwe-CAD-reviewed layout, impendulo ye-DFM malunga neempawu zokunyuswa ngokwesiko, kunye neengxelo zokuhlola ezinobungakanani ezisayinwe ziinjineli ze-QC-hayi nje izatifikethi zebhetshi. Yiloo ndlela abathengi abaphindayo eJamani naseCanada bagcina i-≤0.7% imilinganiselo yembuyekezo yentsimi kwiiyunithi ezili-11,000+ ezithunyelwe ukususela ngo-2021.
I Itafile ye-BRC yemesh iyaphumelela kuba isala ukuthembisa ngokugqithisileyo. Ayizu kuthatha indawo yepleyiti yomphezulu yegranite kwiilebhu zemetrology. Ayiyi kuxhasa i-500 kg imithwalo engatshintshiyo njengebhentshi ye-I-beam edibeneyo. Kodwa apho ukushukuma, isantya sokuthumela, uzinzo lwexesha elide, kunye nobomi benkonzo obuqikelelwayo bubaluleke ngaphezu kobuninzi bethiyori-iyanikezela. Kumaqela adiniweyo kukukhetha phakathi “kokukhanya kodwa kushukuma” kunye “nokuqina kodwa okungashukumiyo,” lo ngumphezulu womsebenzi othi ekugqibeleni uyeke ukunyanzela urhwebo. Yakhelwe apho ubuchwephesha bokwenza ukubanda budibana nesiphumo sokwenyani-kwaye kuvavanywa apho ukunyamezelana kulinganiswa kwii-microns, hayi iincwadana zentengiso.
