Lapho onjiniyela becacisa i-tilt gravity die casting yezingxenye zensimbi ezinobuqotho obuphezulu, abagcini nje ngokukhetha inqubo—bakhetha isu lokulawula. I-Gravity die casting iyodwa ihlinzeka ngokungaguquguquki; amandla adonsela phansi anyakazayo angeza ukuqina okuqondisayo, ukwakheka okusanhlamvu okuqinile, kanye negesi encishisiwe ebanjiwe—okubalulekile lapho kwenziwa ama-valve okucindezelayo noma izindlu zesilinda sephampu ye-piston ukuze kube ±0.02 mm ukubekezelelwa kwe-GD&T. Yingakho abakhiqizi abagxile ngokunemba njenge-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hlanganisa amandla adonsela phansi etshekile emandleni abo ayisisekelo—hhayi njengesengezo, kodwa njengesinyathelo esilinganisiwe ekuhambeni komsebenzi okulawulwa ngokuma mpo.
Sibone amakhasimende eshintsha kusukela ekubunjweni kwesihlabathi okuvamile ukuya ekutshekiseni amandla adonsela phansi ezingxenyeni zephampu ye-cobalt-nickel futhi ngokushesha asika izinsalela zangemuva komshini ngo-37%. Kungani? Ngoba ukutshekiswa kwesikhunta okulawulwayo (okuvame ukuba ngu-15°–30° ngaphezu kwamasekhondi angu-8–12) kuphoqa insimbi encibilikisiwe ingene emgodini ngaphansi kokucindezela kwekhanda okuqinile—hhayi ukuchaphaza okunyakazayo. Umphumela: imigodi eshwabene embalwa eduze kwendawo evalekayo ebalulekile, ukujiya kodonga olufanayo ezindlini ezinodonga oluncane ze-AMS 5387, kanye nesakhiwo esincane esingabikezelwa kuwo wonke amabhomu engxubevange ye-T800 afakwe ukushisa. Lokhu akulona ithiyori. Emiqhudelwaneni emithathu ehlukene yokukhiqizwa kwamavalvu e-hydraulic ngonyaka odlule, ukujikijelwa kwamandla adonsela phansi anyakazayo kudlule u-100% wokuhlolwa kwe-ultrasonic ngo-5 MHz—ngenkathi ukusakazwa kwejiyomethri okufanayo nge-static gravity kwehlulekile ngo-12% ku-porosity engaphansi komhlaba.
Kodwa i-tilt gravity die casting iletha inani kuphela uma ihlanganiswe ngokuqinile neziyalo ezingezansi. Indlu yensimbi etshekile isho okuncane uma ukwenziwa kwe-CNC kuyihlanekezela ngesikhathi sokukhonkoloza kwe-axis emihlanu—noma uma ukwelashwa kokushisa kusonta i-eksisi yokubhoboza. Yilapho ukuhlanganiswa okuqondile kuba okungaxoxiswana khona. Esikhungweni se-QINGDAO QIANGSENYUAN esithobela i-ISO, ithimba lonjiniyela elifanayo eliqinisekisa umdwebo wakho we-engeli ye-mold tilt liphinde lihlele i-Mazak INTEGREX i-200S eqeda ukuhlukana kwangaphakathi, bese lisayinda embikweni wokugcina we-CMM ngokumelene nama-callout akho e-ASME Y14.5 ncamashi. Awekho ama-handoffs. Akukho ukwehluka kwenqwaba yenqwaba—isitoko esingavuthiwe siyaqinisekiswa, siyalandeleka, futhi siqinisekiswa kusengaphambili ngokulingana kwekhabhoni nosayizi wokusanhlamvu ngaphambi kokuncibilika. Lapho i-OEM yaseYurophu idinga amayunithi angama-240 we-winch centre shaft roller engajwayelekile ngensimbi engagqwali i-CF8M, saqhuba izivivinyo zamandla adonsela phansi amatshekisiwe ngamaphrofayili amathathu okushisa angaphambi kokushisa, sakala ukusatshalaliswa kwe-thermal gradient ngama-thermocouples ashumekiwe, futhi sikhiyelwe kuleso esilethiwe. <0.05 mm ukuhlanekezela ngemva kokudambisa ingcindezi. Lelo zinga lokulawula iluphu elivaliwe alilingani nokukhishwa kwemisebenzi.
Abanye bangase baphikise ukuthi amandla adonsela phansi etshekile ayaqina kuma-oda evolumu ephakathi—ikakhulukazi lapho i-aluminium die casting inikeza izikhathi zomjikelezo osheshayo. Kepha lokho kugeja iqiniso lezinto ezibonakalayo: ama-cobalt alloys awahambi njenge-A380. Bafuna ukuphathwa okunembayo okushisayo, hhayi isivinini. Amandla adonsela phansi atshekisayo asinika isikhathi nokuqondisa ukuze siphakele ukukhula kwe-dendritic kude nezindawo ezithwala imithwalo. Kusivumela ukuthi silethe izici ezinjengama-fins okupholisa awugqinsi ongu-2.3 mm ezingxenyeni zephampu ze-AMS 5387 ngaphandle kokuvala okubandayo—futhi sibambe ubuhwaqane obungaphezulu ngaphansi kuka-Ra 6.3 µm as-cast, kwehlise izindleko zokuqeda ngo-22%. Silandelela yonke ipharamitha yokutsheka—isilinganiso serempu ye-engeli, sithela ukuchezuka kwezinga lokushisa, ukujiya kwesikhunta—ku-MES yethu. Uma i-shift ichezuka ngaphezu kuka-±1.5°C ukusuka endaweni yokubeka, isistimu ihlaba umkhosi inkatho ngaphambi kokuqala komshini. Yileyo ndlela esiqinisekisa ngayo ukulandeleka okugcwele kwawo wonke amavalvu okucindezela athunyelwa kumakhasimende kawoyela negesi aseNyakatho Melika.
Imboni yeqiniso ye-tilt gravity die casting ithola igama layo hhayi ngezincwajana zemishini—kodwa ngemiphumela ebhaliwe ezingxenyeni ezibalulekile zemishini. Kungumehluko phakathi kwe-spec yomhlangano nomsebenzi odlulayo: ipulaki ye-cobalt alloy evala ku-4,200 psi ngaphandle kokuvuza okuncane; indlu yephampu yepiston esinda emahoreni ayi-15,000 kusevisi ye-slurry abrasive; umlomo wombhobho we-T800 wangokwezifiso ogcina ukuzinza kwe-dimensional ngemva kwemijikelezo engu-8 yokushisa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayiphathi amandla adonsela phansi etshekile njengendlela yokuphonsa, kodwa njengendlela yokuqondisa insimbi—egxiliswe kusayensi yezinto ezibonakalayo, eqinisekisiwe ekukhiqizeni, futhi eqinisekisiwe ngokwephrothokholi yokuhlola yekhasimende ngayinye. Konjiniyela abacacisa izingxenye lapho ukwehluleka kungeyona inketho, umbuzo awukona ukuthi amandla adonsela phansi enyakazayo angeza izindleko. Kungakhathaliseki ukuthi ungakwazi ukukuyeka.
