Xa iinjineli ze-aerospace zidinga iiblade ze-iturbine, imilomo yepetroli, okanye izindlu ze-actuator ezibamba ± 0.02 mm ukunyamezela ngaphantsi kwe-1,200 ° C ukukhwela ibhayisekile ngokushushu-akukho ndawo yokulalanisa Umzi mveliso wotyalo-mali lwe-aero bayakhetha. Sibone iiprojekthi ezininzi zilibazisekile ngokuqhutywa yidimensional drift kwi-cobalt-based castings, okanye iibhetshi ezilahliweyo ukusuka kwi-micro-porosity kwizinto ezinodonga olucekethekileyo lwe-AMS 5387. Ukusebenza kwehlabathi lokwenyani akuqali ngencwadana ecwebezelayo-kodwa ngolawulo lwe-metallurgical, iifestile zenkqubo ephindaphindwayo, kunye nokunyamezelwa kwe-zero kwizithuba zokulandela umkhondo.
Kutheni le nto uTyalo-mali lufuna ngaphezulu kune-Foundry nje
Ukwenziwa kotyalo-mali “ayisiyonto nje enye inkqubo” yezahlulo ze-aerospace-kuphela kwendlela esebenzayo yeejiyometri ezinobume obunomnatha obunamatshaneli okupholisa angaphakathi, iifoyile zomoya ezintsonkothileyo, okanye iimpawu ezidityanisiweyo zokukhwela. Kodwa ayizizo zonke iziko elibonelela ngemveliso yokwenyani ye-aerospace-grade. Sivavanye ngaphezulu kwababoneleli abangama-40 kulo lonke elaseAsia naseMpuma Yurophu. Inqaku lokungaphumeleli elingaguqukiyo? Ukuphatha utyalo-mali njengenyathelo elizimeleyo-endaweni yokuyidibanisa ngokuqinileyo nesayensi yezinto, umatshini kunye nonyango lobushushu.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-cobalt ialloy nozzle nganye okanye i-T800 yezindlu zempompo njengenkqubo: isiqinisekiso semathiriyeli ekrwada (AMS 5719, ASTM A494), uqinisekiso lozinzo lwepateni yewax, iqokobhe leceramic permeability mapping, ukugalelwa kwe-vaxing ramp-incopho, amanqanaba e-vaxing alawulwayo kunye ne-vaxing-ramp-cast-ramp, i-vaxing elawulwayo ukucoca-konke kufakiwe, kubekwe ixesha, kwaye kubhekiswa kwindawo yokuqala yobushushu. Yiyo indlela esigcina ngayo ukwakheka kweenkozo kumacandelo angama-120 mm-thick ngelixa sibambe i-Rz ≤ 1.6 μm umphezulu wokugqiba ubuso obubalulekileyo bokutywinwa.
Oku akuyothiyori. I-OEM enye ye-injini yomoya yaseMntla Melika yatshintshela kuthi emva kokuba amaqashiso amathathu alandelelanayo e-AMS 5387 vanes engaphumelelanga kuhlolo lwe-ultrasonic kwi-80% yesivuno. Unobangela weengcambu? Ukufuma okungaguquguqukiyo kokomisa iqokobhe kwihonti yomthengisi wabo wangaphambili. Sifake i-RH esweni ngexesha lokwenyani kwii-oveni zethu zokomisa iqokobhe-kwaye sazisa i-99.4% yesivuno sokuqala sokupasa kwiinyanga ezili-18.
Apho uHlanganiso oluthe nkqo luba luNgaxoxiswana
Abanye ababoneleli benza oomatshini bangaphandle. Abanye unyango lwe-subcontract yobushushu. Olo qhekeko ludala iindawo ezingaboniyo: isithukuthezi esenziwe ngoomatshini sinokudibana ne-GD&T-kodwa iprofayile yayo eshiyekileyo yoxinzelelo inokubangela imfazwe ngexesha lenkonzo. Sine-chain epheleleyo-i-casting, i-multi-axis CNC (i-5-axis DMG MORI NTX 1000), isisombululo sokuguga, i-HIP, kunye ne-passivation-ngoko zonke izigqibo zondla isigaba esilandelayo.
Ngokomzekelo, izindlu zethu ze-piston pump cylinder ziqala nge-investment-cast 17-4PH insimbi engenasici. Endaweni yesisombululo esiqhelekileyo se-anneal, sisebenzisa umjikelo we-thermal onenqanaba ezibini ocinezela kwangaphambili ummandla webhore *phambi* kokujika kokugqibela. Isiphumo: I-40% ngaphantsi kwe-post-machining ukuphazamiseka ngexesha lokuvavanya uxinzelelo lwe-hydraulic kwi-bar ye-420. Abathengi ababuzi "iinkcukacha zenkqubo" -babuza "kutheni inxalenye yakho yasinda kwimijikelezo ye-500,000 xa yethu yaphuka kwi-120,000?" Impendulo ihlala kulandelelwano lwe-thermal.
Sikwabethelele i-metrology *ngaphakathi* kwindlela yokusebenza-hayi nje ekujongweni emasangweni. Yonke into eyenziwa yi-CT scanning yemfezeko yangaphakathi phambi komatshini. Yonke inxalenye engoomatshini ifumana ukuqinisekiswa kwe-CMM ngokuchasene nemodeli ye-CAD yasekuqaleni-hayi nje imilinganiselo yegama, kodwa ukuhanjiswa kwempahla yokwenene. Loo datha ibuyela kwi-algorithms yembuyekezo yezixhobo zepatheni. Lulawulo oluphindaphindiweyo-hayi ukuthotyelwa okumileyo.
Ubungqongqo behlabathi lokwenyani: Ngaphaya kweziQinisekiso eDongeni
I-ISO 9001 ziziteki zetafile. I-AS9100 Rev D inyanzelekile. Kodwa eyona nto ibalulekileyo yindlela loo migangatho iguqulela ngayo kwizigqibo zemihla ngemihla. Xa umthengi ecela i-non-standard T800 alloy center shaft roller ye-offshore winch system, asicaphuli nje ixesha elikhokelayo-siqhuba uphononongo lwe-manufacturability: Ngaba i-angle ye-32 ° ye-helix inokwenzeka ngaphandle kokutshintsha okungundoqo? Ngaba ubukhulu bodonga lwe-0.8 mm kwi-flange bufuna ukuqiniswa kweqokobhe lesibini? Ngaba i-Ra 0.4 μm echaziweyo inokufezekiswa ngaphandle kwe-electropolishing-eziphi iingozi eziguqula i-surface carbide dispersion?
Siphendula loo mibuzo ngokubaleka kovavanyo—hayi intelekelelo. Umgca wethu wokulingwa ukhupha iiyunithi ezi-3-5 usebenzisa izixhobo zokuvelisa, emva koko uzibeke ekuqinisekisweni okusebenzayo: uvavanyo lwe-tensile nge-ASTM E8, ukuqina kweprofayili kuwo wonke ubukhulu becandelo, kunye nokuhamba ngebhayisikile ngokudinwa phantsi komfanekiso ofanisiweyo womthwalo. Kuphela kungoko sikhupha umyalelo opheleleyo. Yiyo loo nto inqanaba lethu lokuphinda uodolo ukusuka kwi-OEMs ye-hydraulic valve yaseYurophu idlula i-82%-hayi ngenxa yokuba sinexabiso eliphantsi, kodwa ngenxa yokuba amaqela abo obunjineli ayeka ukucima umlilo kwaye aqale ukwenza izinto ezintsha.
Ukulandelelwa kweMathiriyeli ayilongeniso yedatha. Yikhowudi ye-QR yekhowudi ye-laser efakwe kuyo yonke into yokuphosa, edityaniswe newele ledijithali elibonisa ikhemistri enyibilikayo, i-log yeqondo lobushushu, igophe lokupholisa, kunye nazo zonke iingxelo zokuhlola. Ukuba inxalenye ethile ayisebenzi kwinkonzo yasentsimini, siphinda siwulungelelanise wonke umjikelo wayo ngemizuzu engaphantsi kwama-90.
Ukukhetha i-Aero Investment Casting Factory yakho ayikho malunga neJografi-Imalunga neNkqubo yobunini
I-aerospace ayivuzi isantya sodwa. Ivuza ukuqikelela. Uzinzo lweDimensional. Ukuphindaphinda kweMetallurgical. Ukuphendula ngekhonkco elipheleleyo. Uza kufumana iifektri ePoland, eMexico, naseMalaysia ezinikezela ngeenkonzo “zefektri yotyalo-mali lwe-aero”-kodwa bambalwa abalawula ubungakanani bengqolowa ye-alloy *ngaphambi kokugalela*, qinisekisa i-microstructure *emva* kwe-HIP, kwaye uqinisekise ukusebenza okusebenzayo *phambi kokuthumela* ngenqanawa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka eQingdao-kungekhona njengenye indlela enexabiso eliphantsi, kodwa njengeqabane elichanekileyo lemishini ebalulekileyo yentsimbi. Sisebenza ngokukhethekileyo apho abanye benza ngokubanzi: iialloyi ze-cobalt-nickel, izindlu zoxinzelelo oluphezulu lwe-hydraulic, iirola zeshaft ezinxitywayo, kunye neendibano zempompo ezingezizo ezisemgangathweni ezifuna zombini imfezeko yesakhiwo kunye ne-micron-level geometry. Akukho prototypes zingxanyiswa. Akukho ziqinisekiso zithathwayo. Yonke inxalenye ihambisa ubungqina-kungekhona izithembiso.
Ukuba iprojekthi yakho elandelayo yokuphosa i-aerospace ixhomekeke ekuchanekeni kwe-dimensional, ukungaguquguquki kwezinto, okanye ukuthembeka kokusebenza-qala ngokubonakala kwenkqubo. Hayi izilogeni zokuthengisa. Ngenxa yokuba kwizicelo eziphezulu zokusebenza, umahluko phakathi kwempumelelo kunye nokungaphumeleli awulinganiswa ngeedola. Ilinganiswa kwii-microns, i-megapascals, kunye nokunyamezela komjikelo wesigidi.
