M'mafakitale okhala ndi phokoso, m'nyumba zosungiramo zinthu zodzaza ndi anthu ambiri, komanso m'ma laboratories oyera, mawilo ali ngati "matayala" chete, akunyamula zida ndi katundu mwakachetechete, akumaliza mayendedwe olondola nthawi ndi nthawi. Anthu ochepa amasamala momwe amasinthira kuchoka pa mulu wa zitsulo zozizira ndi zinthu za polima kukhala "malo olumikizirana" omwe amatha kupirira matani masauzande ambiri ndipo amakhala osinthasintha komanso okhutiritsa. Masiku ano, tikuyandikira ndikusanthula njira yonse yobadwira ya gudumu la mafakitale, kuti tiwone momwe kupanga molondola kumathandizira "mawilo ang'onoang'ono" kunyamula "makampani akuluakulu".
1. Kapangidwe: Sinthani zofunikira kukhala manambala
Chilichonse chimayamba ndi kufunikira. Kodi katundu ndi wotani? Kodi nthaka ili ndi makoma? Kodi mukufuna kupirira kutentha kwambiri, madontho a mafuta, ndi magetsi osasinthasintha? Opanga mapulani amasintha "ma adjectives" awa kukhala ma load curve, ma friction coefficients, ndi Shore hardness, kenako amawayika mu CAD/CAE systems. Mu 3D model, curvature ya gudumu, bearing clearance, ndi bracket intensive angle zimachotsedwa mobwerezabwereza; Finite element analysis imawonetsa kuchuluka kwa kupsinjika kulikonse komwe kungachitike ngati chenjezo lofiira. Musanamalize zojambulazo, ndikofunikira kuchita mayeso enieni pogwiritsa ntchito zigawo zoyesera mwachangu - pokhapokha deta ikadutsa "kufufuza" kwa pansi ndi komwe ingalowe gawo lotsatira.
2. Kusankha zinthu: Gwiranani chanza pakati pa magwiridwe antchito ndi mtengo wake
Zipangizo ndi 'ukadaulo wosawoneka'.
-Muyenera kukhala chete ndikuteteza pansi - sankhani polyurethane, yomwe imakhala ndi kusinthasintha kwabwino komanso imayamwa mwamphamvu kugunda kwamphamvu;
-Kupirira kutentha kwambiri kwa 250 ℃ - pogwiritsa ntchito phenolic resin yapadera kapena chitsulo choponderezedwa;
-Yoletsa dzimbiri - 316L chitsulo chosapanga dzimbiri kapena nayiloni yophimbidwa;
-Yopepuka komanso yoyendetsa mpweya - chophimba cha nayiloni cholimbikitsidwa ndi ulusi wa kaboni + graphite.
Akatswiri a zinthu amayesa mobwerezabwereza magwiridwe antchito, mtengo, ndi nthawi yoperekera zinthu kuti apeze njira "zoyenera".
3. Kupanga Mawilo: Kuyika mamolekyu ndi zitsulo zonse pamalo oyenera
1). Thupi la gudumu lachitsulo: Kusungunuka → Kuponya kotsika → Kutembenuza kwa CNC → Kulinganiza kwamphamvu ndi kuchotsa kulemera kuti zitsimikizire kuti kuzungulira kwazungulira <0.1mm;
2). Malo ozungulira mawilo a polyurethane: kuyeretsa vacuum ya prepolymer → centrifugal casting → secondary vulcanization pa 110 ℃ kuti apange gawo lolimba losawonongeka;
3). Gudumu la nayiloni: Choyamba ikani mluza m'mimba, kenako ikani mu nkhungu ndikugwiritsa ntchito nkhungu yothandizidwa ndi nayitrogeni kuti muchepetse kulemera ndikuchotsa kufupika.
Mosasamala kanthu za njira yochitira zimenezi, "zenera la kutentha" limayendetsedwa mosamala pa ± 2 ℃ - kakonzedwe ka maunyolo a polima ndi kukula kwa tinthu tachitsulo zimatsimikiziridwa mwakachetechete pakati pa madigiri ochepa awa.
4. Bracket ndi foloko: kutumiza mizere yamphamvu pansi mokongola
Pambuyo pochotsa zitsulo pogwiritsa ntchito laser ndi kupondaponda kasanu motsatizana, zinthu zopangidwa ndi chitsulo zimapangidwa, kenako ma angles a "gooseneck" ndi "slant support" amamalizidwa pa makina opindika a 3D CNC nthawi imodzi; Ma key welds amasungunukanso ndi robot TIG, kuonetsetsa kuti kuya kwa ≥ 30% ya makulidwe a mbaleyo kuli kozama. Chithandizo cha kutentha chimagwiritsa ntchito martensitic isothermal quenching, yokhala ndi kuuma kwa HRC42 pomwe imasunga kulimba kwa 8J. Pambuyo pake, malo onse oyika mabowo amayesedwa kudzera mu kuyang'ana pa intaneti, ndipo malo olekerera mabowo sapitirira 0.05mm - kusiya malire okwanira a "ulusi" kuti akonzedwe pambuyo pake.
5. Mabearings ndi ma axles: "mtima" wa moyo wozungulira
Chipinda chonyamuliramo chimasonkhanitsidwa m'chipinda chosonkhaniramo chokhala ndi ukhondo wa 1000. Mafuta odzola amagwiritsa ntchito ufa wa lithiamu wopangidwa ndi kutentha kwakukulu + PTFE micro powder, womwe sutulutsa mafuta pa -40 ℃ ~ 150 ℃; Pamwamba pa wheel axle choyamba pamakhala nickel plated kenako ndikuzunguliridwa, ndi Ra ≤ 0.2 μ m, kuti "asamalire" mwachindunji ma sprouts a micro motion wear. Kuthamanga 100% mu mayeso musanachoke ku fakitale: Kuzungulira kosalekeza kwa 20km pansi pa nthawi 1.5 ya katundu woyesedwa, ndi kugwedezeka kwa mtengo wochepera 5%, kumaonedwa kuti ndi koyenera.
6. Kukonza pamwamba: Valani "suti yogwirira ntchito" pa chitsulo
Cholinga cha mayeso opopera mchere ndi maola 1000. Pamwamba pa bulaketi pamagwiritsa ntchito njira zitatu za "zinc nickel alloy electroplating + chromium free passivation + powder spraying", yokhala ndi makulidwe a filimu a 60-80 μ m ndi mulingo woyeserera wa 0. Pazochitika zomwe conductivity ikufunika, arc spraying zinc iyenera kugwiritsidwa ntchito ndi kukana pamwamba kosakwana 0.1 Ω kuti zitsimikizire kutulutsa kwa magetsi nthawi yomweyo.
7. Kukonza komaliza: Pindani njira zambirimbiri kukhala "screw" imodzi
Mzere wosonkhanitsira umagwiritsa ntchito "kukoka kolimba":
-Kuyika chidebe cha mawilo → Kuika mafuta okha →
-Makina odulira pa bulaketi kuti apange kamodzi kokha →
-Limbitsani mfuti ya torque motsatira njira ya ngodya →
-Kuyang'ana pa intaneti kwa ma gaskets omwe akusowa →
-Chitani kukanikiza kwa static load ka 2.5 pa nambala yomaliza kwa masekondi 30 kuti mutsimikizire kuti palibe kusintha kulikonse.
Sikani khodi ya MES panthawi yonseyi, ndipo ngati mphamvu kapena kukula kulikonse kuli kosayenera, makinawo adzatseka nthawi yomweyo malo ogwirira ntchito kuti aletse "zolakwika" zilizonse kulowa mu gawo lotsatira.
8. Kuyesa ndi Chitsimikizo: Lolani Deta Ilankhule pa Gudumu
Kuwonjezera pa katundu wamba, kukana kuzungulira, kupopera mchere RoHS， Laboratory imatsanziranso 'malo obisika':
-Kugunda kosalekeza nthawi 50000
-Kuyimitsa mwadzidzidzi kwa 1.8m/s kumakoka liwiro lalikulu
-Kukwera kwambiri kwa kutentha -40 ℃ ↔+ Yendani nthawi 200 pa 80 ℃.
Pokhapokha podutsa mayeso a "chilango" awa ndi pomwe mawilowo angakhale ndi QR code yawoyawo ya "ID card" - makasitomala amatha kutsatira batch, nambala ya uvuni, makina ogwiritsira ntchito, komanso kutentha ndi chinyezi cha workshop panthawiyo pofufuza.
9. Kusintha: Gawani zigawo zokhazikika kukhala "mawonekedwe osakhazikika"
Poyang'anizana ndi "mtunda womaliza" wapadera, mainjiniya amachita "kuwonjezera ndi kuchotsa" papulatifomu yokhazikika, monga kusintha ma ceramic bearing, kuwonjezera mafuta opaka mafuta osatentha kwambiri, ndikutsegula ma ducts ozizira a mpweya m'mabulaketi, m'ma workshop opangira aluminiyamu okhala ndi kutentha kwakukulu kwa 280 ℃, mafakitale a semiconductor okhala ndi mulingo wopanda fumbi wa ISO5, ndi malo a thanki ya mankhwala omwe amafunikira kupewa kuphulika; Kapenanso, pamwamba pa gudumu pakhoza kupangidwa ndi anti-static polyurethane ndi unyolo woyambira kuti muwonetsetse kuti kukana kuli kochepera 10 ΩΩ. Pangani dongosolo mkati mwa maola 48 ndikupereka gulu loyamba la zitsanzo mkati mwa masiku 7 - zomwe zimapangitsa kuti "zosakhala zachizolowezi" zisakhalenso zofanana ndi "kudikira kwa nthawi yayitali".
10. Kutsiliza: Pamene gudumu likhudza pansi koyamba
Musanapake, gudumu lililonse lidzakulungidwa mu thumba la PE lomwe lingawonongeke ndikuyikidwa mu bokosi la makatoni kuti muchepetse kuchuluka kwa mpweya woipa womwe umanyamulidwa. Zitha kupita ku mizere yopangira yokha ku Germany kapena kuyikidwa m'zidebe za zida za dzuwa ku Africa. Kaya zipita kuti, zida zikagwa pang'onopang'ono ndipo magudumuwo akagundana ndi pansi, "kuguguda" pang'ono kumeneko ndiye mapeto abwino kwambiri a ulendo wopangira zinthu molondola komanso chiyambi cha ntchito yopitilira ya mafakitale.
