Izixhobo zetsimbi eziphakamileyo azinyamezeli ukulungelelanisa-ingakumbi kwiinkqubo ze-hydraulic, i-oyile kunye ne-gas valves, okanye i-winch shafts yemoto yobunjineli. Xa uzinzo lwe-dimensional, imfezeko ye-microstructure, kunye nokumelana nokunxiba kufuneka kubambe phantsi koxinzelelo lwe-bar ye-300+ okanye i-600 ° C ukuvezwa okungapheliyo, ukuchithwa kwendabuko okanye ukuphosa yedwa kuyawa. Kulapho ubuchwephesha befektri yesinyithi somgubo buguquka busuka kukhetho busiya kwimfuneko-kungekhona njengenkqubo ezimeleyo, kodwa njengesixhobo sobuchule sokwenza izinto ngaphakathi kwenkqubo yokuvelisa ethe nkqo edityanisiweyo.
Kutheni i-Powder Metallurgy yodwa ingeyiyo impendulo (kwaye yintoni)
Iinjineli ezininzi zicinga ukuba "umgubo wesinyithi" uthetha iinxalenye ezifakwe ngqo kumatshini wokushicilela. Ngokwesiqhelo, loo nto ayifane inikeze umphezulu ogqityiweyo, amandla okuqina, okanye ubomi bokudinwa obufunekayo kwizindlu zempompo ze-cylinder okanye i-AMS 5387 cobalt alloy nozzles. Siye sabona iindlela ezintathu zokungaphumeleli eziphindaphindiweyo: ukuvuza okubangelwa yi-porosity kwimizimba yevalvu yoxinzelelo, ukwakheka kweenkozo okungahambelaniyo kuzo zonke iiplagi ze-T800 ezifakwe ubushushu, kunye nokutenxa kwe-GD&T emva komatshini wesibini ngenxa yokushwabana kwemeko eluhlaza.
Isisombululo sokwenyani asikhethi * phakathi kwe-* powder metallurgy kunye neendlela eziqhelekileyo-zilandelelanisa ngobulumko. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha isinyithi somgubo kungekhona njengesiphelo, kodwa njengenqanaba elichanekileyo. Inxalenye yealloyi ye-cobalt-nickel iqala njengendawo ekufutshane ne-net-shape sintered blank-emva koko ihamba ngokuthe ngqo kwi-5-axis CNC machining eneendlela zesixhobo ezilungiselelwe intsalela yemithamo yoxinaniso. Akukho ukulungiswa kwakhona. Akukho ukothuka kwe-thermal ukusuka kwimijikelo eyahlukileyo yonyango lobushushu. Ukuhamba komsebenzi omnye oqhubekayo ukusuka kumgubo ukuya kumphezulu osebenzayo.
Izakhono ezine eziguqula iMetallurgy yePowder ibe yintsebenzo eqikelelweyo
Oku akuyothiyori. Yakhelwe kwiziko lethu elithobela i-ISO e-Qingdao-kwaye yangqinwa kuyo yonke i-127 yenkqubo yokwenziwa kolwelo olwenziwa ngamanzi kwisithuba seminyaka emihlanu edlulileyo. Nantsi into eyenza ukuba isebenze:
- Material-Inkqubo Ulungelelwaniso Lockstep: Sisebenzisana nokuphuhlisa iinkcukacha ze powder kunye nabanikezeli abaqinisekisiweyo-kungekhona nje ukubunjwa kweekhemikhali, kodwa ukusabalalisa ubungakanani be-particle (D50 = 15-18 µm) kunye nokuhamba (≤25 s / 50g Hall Flow). Ngoba? Ngenxa yokuba i-3% ye-3% yokutshintsha koxinano olubonakalayo lutshintsha i-sintering shrinkage nge-0.012 mm-ngokwaneleyo ukuphula ± 0.025 mm ukunyamezela isikhundla kwi-piston pump housing bore.
- Iiprofayili ze-Machining-Centric Sintering: Imijikelezo yethu yesithando somlilo ayimiselwanga ubunzima obukhulu. Zilungele ukulungelelanisa: ukubamba kwi-1180 ° C kwimizuzu ye-90 phantsi kwe-argon, emva koko ilawulwa ukupholisa ukugcina isiseko se-25-35 ye-HRC-ethambileyo ngokwaneleyo ukwenzela ukuba izixhobo ze-carbide zigawulwe ngokucocekileyo, nzima ngokwaneleyo ukuxhathisa i-galling ngexesha lokugqibela.
- GD&T-Aware Secondary Operations: Zonke iindawo ezisiniweyo ziskenwa ngeCMM *phambi* komatshini—kungekhona emva koko. Senza imephu yejiyometri njenge-sintered ngokuchasene ne-CAD yegama, emva koko sivelise iindlela zezixhobo eziguqukayo ezihlawulela ukushwabana kwendawo. Isiphumo: I-94% yesivuno sokuphumelela okokuqala kwiikhontolo ezintsonkothileyo ezifana neerola zeshaft ezingeyiyo i-winch centre.
- Ukulandelelwa phantsi ukuya kwinqanaba leBatch: Iqashiso ngalinye liphethe amaxwebhu apheleleyo-kungekhona nje iziqinisekiso zezinto eziphathekayo, kodwa iilogi ze-sintering atmospheric, iingxelo zoqinisekiso loxinaniso, kunye noburhabaxa bomphezulu wangemva komatshini (Ra ≤ 0.4 µm) kulinganiswa ngeprofilometry ye-optical. Akukho ngqikelelo. Akukho handoffs ngaphandle data.
Apho iPowder Metallurgy Factory Solutions eneneni ihambisa iROI
I-ROI ayithethi malunga namalungu ashibhile. Imalunga nokuphelisa iindlela zokungaphumeleli ezixabisa ngaphezulu komsinga. Cinga nge-AMS 5387 ingxubevange ye-cobalt 6 yempompo yeendawo: utyalo-mali oluqhelekileyo lufuna imisebenzi e-7 (ipateni yewax → ukwakha iqokobhe → ukudinwa → galela → HIP → umatshini orhabaxa → umatshini wokugqiba). Indlela yethu exutyiweyo iyayinqumla iye ku-4 (cofa → sinter → i-adaptive CNC → ipasi lokugqibela). Ixesha lokukhokela liyehla ukusuka kwiiveki ezili-14 ukuya kwezi-6. Izinga le-Scrap lehla ukusuka kwi-18% ukuya kwi-3.2%. Kwaye umlinganiselo obalulekileyo we-CPK uhlala ngaphezu kwe-1.67-kuba i-shrinkage ayinanto nje; imodeli, ilinganisiwe, kwaye ibuyekezwe.
Kodwa eyona mpumelelo inkulu yinkululeko yoyilo. Omnye umthengi waseYurophu wayefuna umzimba wevalve yoxinzelelo kunye nemijelo yokupholisa yangaphakathi edibanisa kwi-37 °-akunakwenzeka ngokutsalwa kwe-core kwi-santi casting, ebiza kakhulu nge-EDM yokugaya kwisitokhwe esisetyenzisiweyo. I-Metallurgy yomgubo masizinzise ii-polymer cores zedini *ngexesha lokucinezela*, emva koko sizitshise ziphele phambi kokuba sincwine. Oomatshini bacoca iindawo zokungena zesitishi kuphela. Lilonke ixesha lophuhliso: 11 iintsuku. Iprototype yokuqala esebenzayo iphumelele uvavanyo lokuqhuma kwi-412 bar.
Ukukhetha iFactory yakho yePowder Metallurgy: Iitshekhi ezintathu ezingaxoxisiyo
Ayizizo zonke iifektri zomgubo wesinyithi ezisebenza kweli nqanaba. Ngaphambi kokuba uthumele imizobo, buza le mibuzo:
- Ngaba uyayenza inkqubo yoqinisekiso loxinaniso *kwiqashiso ngalinye*—hayi nje ishifti nganye? (Ukuba bathi "ewe" kodwa abanakukubonisa ifomathi yelog, hamba.)
- Ngaba abadwelisi benkqubo bakho be-CNC banokungenisa ifayile yakho ye-STEP *kwaye* bagqume ingxelo yakho ye-CMM ene-sintered ukuvelisa iindlela zesixhobo zokubuyekeza? (Ukuba isoftware yabo ye-CAM iphatha i-sintered blanks njengeziqina ezigqibeleleyo, lindela ukusebenza kwakhona.)
- Xa sicacisa i-AMS 5387 okanye i-T800, ngaba ukhupha umgubo kumthengisi omnye ofanelekileyo-kwaye wabelane ngeengxelo zabo zokuvavanya i-mill * ngaphambi kokuba ucinezele? (Ukuguquguquka kwe-Batch-to-batch kwi-cobalt alloys kubulala ukuhambelana ngokukhawuleza kunayo nayiphi na enye into.)
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. idibana zontathu-kwaye ipapashe sintering inkqubo yokuqinisekisa idata yefestile kwicandelo lobugcisa tsngtaocnc.com. Hayi njengekopi yokuthengisa. NjengeePDF ezikhutshelwayo zophononongo lobunjineli.
Amalungu esinyithi asebenza ngokuphezulu aphumelele xa isayensi yemathiriyeli, ukuchaneka komatshini, kunye nokuziphatha okuhle kuyeka ukusebenza kwizisele. Umzi-mveliso we-metallurgy ongumgubo ocofa kuphela kunye nee-sinters ezihambisa amacandelo. Omnye odibanisa ukuziphatha komgubo kuwo wonke umsebenzi osezantsi-ukuqinisekiswa koyilo, ukuyila ukulungiswa, ukuveliswa kwendlela yesixhobo, ukucwangciswa kokuhlolwa-kuzisa ukuzithemba. Lo ngumqobo esiwela yonke imihla eQingdao. Hayi ngezithembiso. Ngedatha elandelekayo, iinkqubo eziphindaphindwayo, kunye namalungu abambe uxinzelelo xa kungekho enye into enokuyenza.
