Xa iinjineli kuyilo lwenkqubo yolwelo olwenziwa ngamanzi okanye ukuthengwa kwezixhobo ze-oyile zikhangela “ifektri ye-machining inc ephucukileyo,” abakhangeli umboneleli wegeneric. Bafuna iqabane elisombulule ingxaki efanayo yozinzo kwi-AMS 5387 cobalt ingxubevange yempompo yezindlu-kabini-kwaye ibhalwe ukuba ixesha lonyango lobushushu lichaphazele ukubunjwa kwe-microcrack kwi-T800-based nozzles phantsi kwe-280 MPa cyclic loading.
Ukuchaneka kwehlabathi lokwenyani kuqala apho ukunyamezelana kuphelela khona
Siye sabona iindlela ezintathu zokungaphumeleli eziphindaphindiweyo kumacandelo evalve yoxinzelelo oluphezulu: okokuqala, ukuphazamiseka kwe-thermal ngexesha lokugqitywa komatshini wezindlu ze-cylinder ezinqabileyo; okwesibini, imvula engaguqukiyo kumda weenkozo wecarbide ngapha kweziseko zentsimbi; okwesithathu, ukulungelelaniswa kwe-GD&T phakathi kokuphosa imiphezulu yedatum kunye neempawu zokugqibela ze-CNC. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayijongani noku nge-specs ebanzi-kodwa ngokulawula lonke ikhonkco: ukusuka kwi-AMS 5387 ye-billet eqinisekisiweyo yokulandelelwa ukuya kwimijikelo yokukhulula uxinzelelo lwe-post-machining eqinisekisiweyo ngokuchasene ne-ASTM E8M egobileyo. Indawo yabo ehambelana ne-ISO e-Qingdao ayibambeli nje i-± 0.01 mm kwiingxelo ze-CMM-ibambe ukuchaneka * emva * kweeyure ze-48 zokuhamba ngebhayisikili eshushu kwi-120 ° C, kuba yiloo nto i-piston pump assemblies ifuna ekusebenzeni kwangempela.
Ukudityaniswa okuthe nkqo akulogama-yi-inshurensi elinganayo
Uninzi lwababoneleli banikezela ngaphandle okanye ukugqiba. Oko kudala izikhewu ze-handoff: isiseko sinokudibana ne-ASTM A48 yoDidi lwe-35 yentsimbi engwevu, kodwa uburhabaxa bayo bomphezulu bungatshintsha ubunzulu be-CNC ye-toolpath nge-0.03 mm-ngokwaneleyo ukuvusa uphazamiseko kwi-spools zevalvu yoxinzelelo. QINGDAO QIANGSENYUAN ungumnikazi zombini imigca yokuphosa utyalo-mali kunye namaziko machining 5-axis phantsi kophahla olunye. Xa umthengi ethumela umzobo wemoto yobunjineli winch ishaft roller, iqela labo liqhuba ukulinganisa okufanayo: uhlalutyo lokuhamba kwe-Foundry mold * kunye * ne-machining deflection modeling-sebenzisa idatha yedatha efanayo. Isiphumo? Akukho zilophu zokuphinda zisebenze. Hayi "sicinge ukuba ungaluchaza unyango lobushushu." Iphakheji enye ye-GD&T, isicwangciso esinye sokuhlola, inombolo yebhetshi enye elandelekayo ukusuka ekugaleleni ukuya kwi-passivation.
Awukhethi i-alloys-ukhetha iindlela zokungaphumeleli
Amacandelo e-cobalt-nickel awakhethwanga udumo. Bakhethwa ngenxa yokuba ezinye iindlela ziyasilela. Silandele imbuyekezo yentsimi kwiiplagi zempompo zangaphandle: iinguqulelo zensimbi ezingenasici zibonise i-galling emva kwemijikelezo ye-1,200 kwi-180 ° C; I-Inconel 718 iphuhlise i-micro-pitting kwi-flow-induced vibration frequencies ngaphezu kwe-3.2 kHz. Imibhobho ye-cobalt alloy evela kulo mvelisi-eyenziwe kwi-stock ye-T800 ene-carbide dispersion elawulwayo-iqhube imijikelezo ye-14,700 kwiimeko ezifanayo ngaphambi kokutshintshwa okucwangcisiweyo. Ngoba? Ayisiyiyo nje ukwakheka-inkqubo yabo ivalela ubunzima (42-46 HRC) * kunye * noxinzelelo lwentsalela ecinezelayo kumphezulu womgangatho, ingqinwe nge-XRD yokushiyela imephu yoxinzelelo kuyo yonke imveliso. Ukuba isicelo sakho sifuna>ubomi benkonzo yeeyure ezingama-300 kwiindawo ezinodaka olunodaka, loo mahluko awunyuki. Lixesha lokusebenza.
Ukuthembeka kokuhanjiswa kuqala kuphononongo lomzobo
"Ungayenza lonto?" ngumbuzo wokuqala ongalunganga. Elona lifanelekileyo: "Yintoni eza kuphuka kuqala-kwaye siyimisa njani?" Ngexesha lophononongo lobunjineli, iqela leQINGDAO QIANGSENYUAN libeka imingcipheko yokwenza izinto ezinobungozi abathengi abaninzi bayaphoswa: i-angle eyi-0.5 ° eyidrafti ebamba isanti kwiipokotho eziphosiweyo, umngxuma oyimfama ubunzulu ukuya kumdayamitha umlinganiselo odlula i-8: 1 yozinzo lokugrumba umngxuma onzulu, okanye umsonto ongeyo-standard onyanzelisa ukudibanisa ixesha le-1. Babuyisela imizobo enengcaciso kunye nezinye iindlela: "Sebenzisa i-ISO 261 M12 × 1.25 endaweni ye-pitch ye-1.18mm yesiko-umsebenzi wokutywina ofanayo, ukuhanjiswa ngokukhawuleza kweentsuku ezi-6." Oku akukokunciphisa iindleko. Ukupheliswa komngcipheko ngaphambi kokusika isinyithi. Isicwangciso sabo esicwangcisiweyo siphatha i-prototype iterations kunye ne-medium-volume runs (50-500 pcs) ngaphandle kwe-schedule slippage-kuba i-lean workflow practices ibhaka kumaphepha omzila, ongeyongezwa njengophicotho lwe-post-process.
Kumaqela okuthenga ehlabathi akhangela "ifektri ye-advanced precision machining inc," umqondiso ayilolwimi lokuthengisa. Bubungqina: iziqinisekiso zezinto ezilandelekayo kuzo zonke i-AMS 5387 ezithunyelwayo, iingxelo zeCMM ezibonisa ukutenxa kwimo yokwenyani <0.008 mm kwiziseko zempompo ye-12-datum, kunye nezigodo zovavanyo ezisebenzayo eziqinisekisa amazinga okuvuza kwevalve yoxinzelelo kwi-1.5 × ilinganiswe uxinzelelo lokusebenza. Leyo sisiseko-hayi ngaphandle. Njengoko iinkqubo zehydraulic zityhalela ukuya kuma-400 MPa woxinzelelo olusebenzayo kunye neempompo ze-oyile zifuna amathuba eenkonzo zeminyaka engama-20 ngaphandle kokuqhawulwa, ukuchaneka komatshini kuyeka ukuba malunga namalungu. Iba malunga nokusebenza okuqikelelweyo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha oko kuqikelelwa-iplagi enye ye-cobalt alloy, enye indlu yepiston, imilinganiselo eqinisekisiweyo ngexesha.
