Xa iinjineli zaseMntla Melika okanye eYurophu zikhangela utyalo-mali ephosa China, abakhangeli nje ukuveliswa kwexabiso eliphantsi-bafuna ukuzinza kwe-dimensional phantsi kwe-120 MPa yoxinzelelo lwe-hydraulic, i-microstructural consistency kuwo wonke ama-500-part batches, kunye ne-zero ukunyamezela kwi-porosity kwi-cobalt alloy nozzles. Leyo yinyani emva kombuzo. Siye sabona amaqela okuthengwa kwempahla egatya ababoneleli abathathu ngokulandelelana-kungekhona ngaphezulu kwexabiso, kodwa ngenxa yokuba ubukhulu bendonga ye-as-cast yahluka ± 0.35 mm kwi-42-mm-diameter piston pump cylinder housing. Ukuchaneka ayisiyonto yokuzikhethela kwiinkqubo eziphezulu zokunxiba zehydraulic. Yisiseko.
Kutheni “uTyalo-mali luTyala iTshayina” ayisesoSigqibo seendleko kuphela
Kwiminyaka emihlanu edlulileyo, "ukuphosa utyalo-mali eChina" kwakuthetha ukugalelwa kwesanti nge-CNC touch-up-kunye nokuphinda kusetyenzwe rhoqo. Namhlanje, kuthetha ukuba i-ISO 9001-certified foundries eqhuba iinkqubo ezipheleleyo ze-wax ezilahlekileyo: inaliti yepateni ye-wax ku-± 0.05 mm ukunyamezela, ukudubula kweqokobhe le-ceramic ukuya kwi-1,100 ° C, ukulawulwa kokuthululwa kwe-vacuum-assisted, kunye nonyango lobushushu emva kokuphoswa luqinisekiswe luhlalutyo lwe-spectrographic. Utshintsho lwavela kwimfuno—kungekhona umgaqo-nkqubo. Ii-OEM zeHydraulic zazifuna iindawo ezibambe i-callouts ye-GD&T njenge ⌀0.02 mm ukunyamezela isikhundla kwi-8× M12 abaphathi beentambo-ngaphandle komatshini wesibini. Oko kunokwenzeka kuphela xa uyilo lokuphosa, ukhetho lwe-alloy, kunye nobunjineli bokubumba buhlala kwiqela elinye lobugcisa.
Sixhase ukuyilwa ngokutsha kwempompo yempompo engama-27 apho abathengi bathathe indawo yemizimba yentsimbi engatyiwa ngoomatshini kunye nezinto ezilingana notyalo-mali. Isiphumo? I-38% ye-avareji yokunciphisa ubunzima, i-22% ephantsi kweendleko zizonke zeyunithi nganye, kunye nokupheliswa kwe-3-5 yokuseta machining. Kodwa impumelelo yayixhomekeke kwizinto ezimbini ezingenakuxoxisana: ukulandelwa kwezinto eziphathekayo ukuya kwinani lobushushu, kunye nokuqinisekiswa kwe-CMM kwinkqubo kwizigaba ezintathu-kungekhona nje ukuhlolwa kokugqibela.
Apho Uninzi Lwezixhobo Zokukhangela Isilele—Nendlela Yokukuphepha
Abanye abathengi bacinga ukuba bonke abatyali-mali baseTshayina baphatha i-cobalt-nickel alloys ngokulinganayo. Abayenzi. I-AMS 5387 ingxubevange ye-cobalt idinga ukunyuswa okuthe ngqo kwe-thermal ngexesha lokutshiswa kweqokobhe. Ngokukhawuleza okukhulu? IiMicrocracks. Ukucotha kakhulu? Intsalela yekhabhoni. Siye sabona i-41% yereyithi ye-scrap kwi-T800-based based shaft rollers xa i-Foundries iphinda isebenzise i-shell molds ngaphaya kwemijikelo emi-3-akukho silumkiso, akukho ngxelo yengcambu.
Ulungiso alukho izivumelwano ezingqongqo. Ulawulo lwenkqubo oluzinzisiweyo: ukugawulwa kwepyrometer ngexesha lokwenyani ngexesha lokuthotywa, ukujonga uxinzelelo lweoksijini kwigumbi lokugalela, kunye novavanyo lwe-batch-specific tensile kuwo wonke ubushushu. Kwiziko lethu le-Qingdao, iqashiso ngalinye le-AMS 5387 lifumana i-metallography ngaphambi kokukhululwa- kwanakwiprototypes. Akunjalo ngenxa yokuba i-specs ifuna, kodwa ngenxa yokuba i-cluster enye yokubandakanya inokuqalisa ukungaphumeleli kokukhathala kwi-15,000 psi.
- Imilomo yengxubevange yeCobalt: Yenziwe kwiindawo ezingenanto kutyalo-mali kunye ne-≤0.08 Ra umphezulu wokugqiba kwangaphambili
- Iivalve zoxinzelelo: Ifakwe kwi-ASTM A494 CW6MC, ivavanywe kwi-1.5 × yoxinzelelo lokusebenza kunye nokufumanisa ukuvuza kwe-helium
- I-Winch center shaft rollers: Ukunyangwa ngobushushu ukuya kwi-HRC 52-56, ukuqina kwimaphu kwiindawo ezili-12 zeradial
Ezi ayizozinto zekhathalogu. Zizisombululo ezenziwe kuhlalutyo oluphindaphindiweyo lokungaphumeleli-hayi iinkcazo zezakhono zethiyori.
Udibaniso oluthe nkqo olunikezela ngozinzo
Ukukhutshwa kwemisebenzi yangaphandle, ukwenziwa komatshini, kunye nokugqiba ukwahlula abathengisi kuyawuphindaphinda umngcipheko. Ukulibaziseka kokunyanga iqokobhe kutyhala ukucwangciswa kwe-CNC. Isiphene somphezulu esifunyenwe emva kokupholisa amandla okwenza kwakhona-okanye ukukrazula. Siziqhuba zontathu kwiziko elinye elithobela i-ISO: iiseli zokuphosa ezikufuphi ne-5-axis machining amaziko, kunye neelebhu ze-metrology ekwabelwana ngazo kunye nokulandelwa kwemathiriyeli edibeneyo.
Oku akukho malunga nokulula. Kumalunga nokulawula okuguquguqukayo okwenzekayo: ukuphosa ukucutheka kuchaphazela ukugxila kokugqibela; uxinzelelo olubangelwa ngoomatshini luguqula ukugqwesa emva kobushushu bonyango; nokuba i-pH epholileyo ngexesha lokusila itshintsha iiprofayili zoxinzelelo olushiyekileyo kwizindlu ezinodonga olucekethekileyo. Xa elinye iqela lingabanini balo lonke ikhonkco, ii-callouts ze-GD&T zihlala zomelele ukusuka kwipateni yewax ukuya kwikreyithi yokuthumela.
Umzekelo: umxhasi waseYurophu udinga iiyunithi ezili-120 zesiseko sempompo yentsimbi ene-flatness ≤0.1 mm ngaphezu kwe-650 mm. Abakhuphisana bacaphula iiveki ezili-14. Sihambise nge-9-kuba iinjineli zethu zokuphosa zihlengahlengise uyilo lokungena ngokusekwe kumfanekiso wexesha lokwenyani lobushushu, kwaye oomatshini bethu basebenzise isilungiso esifanayo seCMM ukuqinisekiswa kwenqaku lokuqala kunye nokuhlolwa kokugqibela. Akukho handoffs. Akukho kuphinda kutolikwe.
Ukukhetha iqabane lakho loTyalo-mali e-China-Yintoni omele uyiqinisekise ngoku
Sukubuza "Ngaba uyakwenza utyalo-mali?" Buza endaweni yoko:
- "Ndibonise amaqashiso akho amathathu okugqibela e-AMS 5387-kubandakanywa neengxelo ze-spectrographic, i-curve yovavanyo olunzima, kunye ne-shell mold cycle logs."
- "Uqinisekisa njani uzinzo phakathi komatshini kunye nemeko yokugqibela yomatshini? Ngaba usebenzisa iindlela zesixhobo ezihlawulelwa nzima?"
- "Oluphi ubuninzi bobukhulu bodonga lwakho kwi-30-mm yecandelo? Kwaye ulinganisa njani-igobolondo elingenayo, i-pre-pour, okanye emva kokugqiba?"
Iimpendulo zokwenyani zibonisa ukukhula kwenkqubo. Iziqinisekiso ezingacacanga azenzi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza apho ukuchaneka kuhlangabezana noxanduva: ukuphosa iijiyometri ezintsonkothileyo kwi-superalloys, ukubamba ukunyamezelana okuqinileyo ngaphandle komatshini ogqithisileyo, kunye nokuhambisa ukuthembeka okusebenzayo-kungekhona nje iinxalenye. Xa ukhangela utyalo-mali ephosa China, jonga ubungakanani obudlulileyo befektri kunye neziqinisekiso. Khangela ubungqina bokungaphumeleli okulawulwayo-kunye nendlela eyenze ngayo umjikelo wabo olandelayo wokuphosa.
