Xa iinjineli zichaza iigiya zeempompo ze-hydraulic, ii-winch drives, okanye i-high-pressure valve actuators, azifane ziqale ngomgubo wesinyithi. Uninzi lufikelela kuqala kwintsimbi ekhandiweyo okanye i-CNC-machined blanks-de kube uzinzo lwe-dimensional, ukumelana nokunxiba, kunye neendleko ezipheleleyo ngenxalenye nganye ziqala ukutshintsha i-calculus. Kulapho ozinikeleyo ipowder metallurgy gears factory iyeka ukuba yinto eyenye-kwaye iba lolona khetho lusengqiqweni.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sikubonele oku kutshintsha kumazwekazi amathathu. Ipompo ye-OEM yaseMntla Melika icuthe ukuphindaphindeka kwegiya nge-40% emva kokutshintsha ukusuka kwintsimbi ene-sintered ukuya kwi-AMS 5387 cobalt alloy PM gears kwizindlu zabo zomjikelo ophezulu wepiston. Umthengisi wezithuthi zobunjineli baseYurophu unqumle ixesha lokuhamba ngeentsuku ze-11-kungekhona ngokukhawulezisa umatshini, kodwa ngokuphelisa imisebenzi emihlanu yesibini ngokupheleleyo. Ezi yayingezizo iinzuzo zethiyori. Zivela ekulawuleni ukuxinana kwemithamo ngaphakathi kwe ± 0.02 g/cm³, zibambe unyamezelo lwedayamitha yepitch ukuya ku-±0.015 mm kwiigiya zemodyuli eziyi-16, kunye nokuphumeza uburhabaxa bomphezulu Ra ≤ 0.8 µm—njengoko-sintered.
Ukuchaneka kokwenyani kwi-powder metallurgy ayikuko ukucofa uthuli lwentsimbi kwaye uyibize yenziwe. Iqala ngesiqinisekiso sezinto ezibonakalayo: yonke ibhetshi ye-T800 ye-cobalt-based powder ithwala ukulandeleka okupheleleyo kwiiparamitha ze-atomization, umxholo we-oxygen (≤120 ppm), kunye nokusabalalisa ubungakanani be-particle (D50 = 18-22 µm). Siyazikhaba ii powders ngaphandle kwaloo festile-nokuba umthengisi unikezela ngesaphulelo se-15%. Ngoba? Ngenxa yokuba i-0.3% yobuninzi benguqu kwingcambu yegiya idala ukuhla kwe-22% kubomi bokudinwa okugoba phantsi komthwalo we-cyclic. Siqinisekisa loo nto yonke imihla sisebenzisa umgaqo ka-Archimedes kunye ne-micro-CT yokuskena kwiisampulu ze-cores-hayi nje kwiindawo zokugqibela, kodwa kwinqanaba eliluhlaza, elimdaka, kunye ne-sintered.
Umgangatho wethu wemveliso udibanisa ubuchule obuthathu obungaxoxisiyo uninzi lweevenkile ze-PM ziziphatha njengeenkonzo ezahlukeneyo:
- Umoya olawulwayo we-sintering ngolawulo oluchanekileyo lwendawo yombethe (−40 °C ukuya -25°C) kunye nemixube yenitrogen/hydrogen-ibalulekile ekugcineni i-carbide dispersion kwi-cobalt alloys ngaphandle kwe-decarburization
- I-in-die coining isetyenziswe ngexesha lokukhutshwa, kungekhona njengenkqubo yasemva, ukuhambisa ± 0.008 mm ulawulo lokuphuma kwiibhore zegiya ngaphandle kokugaya kwakhona
- Unyango lokushisa olusebenzayo idityaniswe ngokuthe ngqo emva kwe-sintering: isisombululo se-annealing kwi-1180 ° C + ukucima ngokukhawuleza kwe-AMS 5387, kulandelwa ukuguga kwi-845 ° C-ukufikelela kwi-Rockwell C 42-46 ngelixa ugcina i-geometry yezinyo.
Abanye banokuphikisa ukuba iigiya zoomatshini be-CNC zibonelela ngomgangatho ophezulu wokugqiba. Yinyani-kwiijometri ezilula. Kodwa xa umthengi ecela i-22-tooth, i-3.5-modyuli ye-helical gear ene-25 ° i-angle ye-helix, i-spline yangaphakathi, kunye ne-press-fit bore-eyenziwe esuka kwi-T800 bar eqinile-izibalo ziyatshintsha. Isivuno sezinto eziphathekayo siyehla ukuya kuma-38%. Ixesha lomjikelo lidlula imizuzu engama-92. Isixhobo sokunxiba izikhonkwane emva kweenxalenye ezili-17. Inkqubo yethu ye-PM inikezela ngegiya efanayo kumjikelo omnye wokudibanisa, kunye nokusetyenziswa kwezinto ezingama-91%, ixesha le-takt lemizuzu eli-14, kunye nokunxitywa kwezixhobo zero phakathi kweebhetshi. I-gear idibana ne-AGMA Q12 kunye ne-ISO 1328-1 Class 7-ngaphandle kokugaya.
Asiyityhala isinyithi somgubo apho ingekhoyo. Ukuba isicelo sakho sifuna ukubuyisela umva kwegiya kuqiniswe kune-0.02 mm kubushushu bokusebenza, okanye ukuba umthamo wakho womthwalo ubandakanya ukothuka okungaphaya kwe-3× yetorque elinganiselweyo, siya kukuxelela ngaphambili: i-forged + finish-ground iseyeyona ndlela yakho ilungileyo. Kodwa kwii-middle-volume runs (500-10,000 pcs / year), i-high-wear environments (≥200 MPa yoxinzelelo loqhagamshelwano), okanye iinkqubo apho ubunzima, ingxolo, okanye ubunzima bendibano-PM ihambisa i-ROI enokulinganiswa. Omnye umenzi wezixhobo ze-oyile ekuMazantsi mpuma eAsia wathatha indawo ye-12-piece-weld gear carriers kunye neendibano zePM ezineqhekeza elinye. Ubunzima behle ngama-37%. Umsebenzi weNdibano wehla ukusuka kwimizuzu ye-42 ukuya kwi-9. Kwaye i-vibration amplitude kwi-1800 rpm yehla ngo-63%-ilinganiswe kwisayithi nge-laser Doppler vibrometry.
Yintoni eyahlula umntu okwaziyo ipowder metallurgy gears factory ukusuka kwivenkile yentengiso yempahla ayingomthamo-luhlalutyo oluchanekileyo lokusilela. Xa igiya yomthengi isilele kwangethuba kwimpompo ye-subsea, asizange siyitshintshe. Siye sanqumla iyunithi engaphumeleliyo, amaqela e-porosity enziwe kwimaphu ngokuchasene neecontours zoxinzelelo, ukubandakanywa kweoksidi edibeneyo kunye ne-sintering atmosphere logs, kwaye sayila ngokutsha indlela yokuphuma kwecango lokufa. Isiphumo: Ukusilela kwibala elinguziro kwiinyanga ezili-18 kunye neeyure zokusebenza ezingama-47,000.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka eQingdao-kungekhona njengesiseko senjongo ngokubanzi, kodwa njengeqabane elichanekileyo lecandelo leenkqubo apho iigiya zingezizo iindawo ezihambayo. Zizinto zokuthintela uxinzelelo. Ii-ankile zokuhanjiswa kweTorque. Ukudinwa-okubalulekileyo ujongano. Sibenza ngobunjineli ngaloo ndlela-ukusuka ekukhethweni komgubo ngokusebenzisa ukuqinisekiswa okusebenzayo. Iziko lethu liphethe iziqinisekiso ze-ISO 9001:2015 kunye ne-AS9100D, kodwa eyona nto ibalulekileyo yindlela esizisebenzisa ngayo: zonke iinqanawa zegiya ezineengxelo ezipheleleyo ezinobungakanani, iilogi zoxinaniso, ubulukhuni beprofayile kwiflank yezinyo kunye neengcambu, kunye neemicrographs zetsimbi zamacandelo abalulekileyo.
Ikamva lokwenziwa kwezixhobo ezichanekileyo azikhethi phakathi kwe-PM kunye noomatshini. Kukubadibanisa ngobukrelekrele-usebenzisa i-PM kwijiyometri ekufutshane nenetha kunye nengqibelelo yolwakhiwo, emva koko isebenzise ubuncinci, iCNC ekujoliswe kuyo igqibezela kuphela apho umphezulu osebenzayo ufuna oko. Le ndlela ixubileyo-i-machining-machining synergy-kulapho kugxilwe khona kwi-R&D yethu ngoku. Ayikuko ukuthatha indawo yeenkqubo, kodwa ukuphelisa ukulungelelana.
