Xa iinjineli zicacisa ukuchithwa kwesanti kwiingxenye zetsimbi ezichanekileyo, azikhethi nje inkqubo-zibophezela ukuzinza kwe-dimensional stability, microstructural consistency, kunye nokuthembeka komsebenzi phantsi koxinzelelo lwehlabathi lokwenene. Yiyo loo nto"Umzi-mveliso weSanti echanekileyo” ayithengisi ijargon. Ingumda wobugcisa abambalwa abafumana i-Foundries-ingakumbi xa bephethe i-cobalt-nickel alloys, i-AMS 5387 components, okanye izindlu zempompo ezingekho eziqhelekileyo ezisebenza kwi-350 bar kunye ne-220 ° C.
Kutheni ukuphosa kweSanti esemgangathweni kusilela apho ukuchaneka kufuneke kuphumelele
Siye sabona ngokuphindaphindiweyo: abathengi bafumana i-castings kunye ne-± 0.8 mm ukunyamezela kwiibhobho ezibalulekileyo-kuphela ukufumanisa i-cylinder yezindlu eziphazamisayo ngexesha lokunyanga ukushisa, okanye isihlalo se-valve sihluleka ukuvavanywa koxinzelelo ngenxa ye-porosity yendawo kufuphi nendawo yokungena. Ukusatywa kwesanti okuqhelekileyo kuxhomekeke ekunxityweni kwepateni, ukwahluka kweramming ngesandla, kunye neenkqubo zokubopha igeneric. Ukuchithwa kwesanti echanekileyo kuthatha indawo yezo ziguquguqukayo kunye nokuhanjiswa kwengqolowa ye-silica elawulwayo, izibophelelo ze-resin ezizinzileyo ze-thermal, kunye ne-real-time core esweni lobushushu bebhokisi. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke imbunda yesanti idlula phambi kokugalelwa imephu yeX-reyi yoxinaniso-kwaye yimingundo kuphela edlula i-ASTM E94 iNqanaba lesi-2 indlela yolwamkelo lweradiyographic iyaqhubeka nokugalela.
Olu qeqesho lubaluleke kakhulu ngemathiriyeli ye-alloy ephezulu. I-T800 esekwe kwi-Cobalt kunye ne-AMS 5387 iyanyibilika kwi-1,380 ° C. I-contraction yabo ye-thermal yi-37% ephezulu kune-iron engwevu. Umngundo oqhelekileyo wesanti eluhlaza uqhekeka phantsi koko kushwabana. Inkqubo yethu yokuchithwa kwesanti echanekileyo isebenzisa i-ceramic-coated silica molds kunye neendlela zobunjineli bokukhupha umoya kunye nemodeli yokuqinisa ngokulandelelanayo-kuqinisekiswe kuyo yonke imveliso eyenziwa kusetyenziswa i-MAGMASOFT® ukulinganisa kwe-thermal.
Iintsika Ezine Zokuchaneka Kokwenene—Akukokunyamezelwa Nje Ngokungqongqo
Ukunyamezelana okuqinileyo kukodwa akuchazi ngokuchanekileyo. Ziluphawu—hayi unobangela. Eyona nto izisa ukuchaneka okuphindaphindwayo kuzo zonke iibhetshi kukudityaniswa:
- Ukulandeleka kwezinto eziphathekayo kubhakwe kwithegi yokubumba: Yonke ibhetshi iphethe iingxelo zovavanyo olupheleleyo lwelitye, ukudibanisa inombolo yobushushu, kunye nelogi yohlalutyo lwe-spectral-akukho ngaphandle, nakwiprototypes.
- Kwinkqubo ye-metrology ngaphambi komatshini: Sihlola ijometri njenge-cast-cast sisebenzisa i-Zeiss DuraMax CMMs-kungekhona nje iindawo zokugqibela. Ukuba indlu yempompo yepiston ibonisa ukuphambuka kwe-0.12 mm kwi-bore concentricity pre-machining, sihlengahlengisa indawo engundoqo-kungekhona ukulahla inxalenye.
- Ukuphosa-machining handoff eyilelwe kwinkqubo: Iinjineli zethu zidibanisa iinkqubo zokungena kunye neendlela zeCNC engqondweni. Oko kuthetha ukuba izinyusi ezibekwe apho zingayi kuphazamisana ne-5-axis fixture-kunye nee-engile eziyidrafti ezilungiselelwe zombini ukushukuma okusebenzayo kunye nokugqitywa komphezulu wasemva komatshini.
- Ukuqinisekiswa okusebenzayo ngaphambi kokuthunyelwa: Yonke i-valve ye-valve yoxinzelelo idlula uvavanyo lwe-helium yokuvuza kwi-1.5 × uxinzelelo lokusebenza. I-winch center shaft roller iqhuba iitshekhi eziguquguqukayo zebhalansi kwi-3,200 RPM.
Apho iSanti eChanekileyo iDibana neNdlela eziFanelekileyo kwiShishini
Abanye banokuphikisa ukuba ukuphoswa kotyalo-mali kunika ukugqitywa okungcono komphezulu kwiijometri ezinzima. Kodwa kumacandelo afana nezindlu ze-hydraulic cylinder okanye i-oyile kunye neziseko zempompo yegesi-apho ubukhulu bodonga budlula i-45 mm kunye nemijelo yokupholisa yangaphakathi ifuna ukuqinisa umkhombandlela-ukuphumelela kwesanti. Ngoba? Ngenxa yokuba amaqokobhe otyalo-mali aqhekeka phantsi komothuko we-thermal ukusuka kwiindawo ezishinyeneyo. Imibundo yethu yesanti echanekileyo ifunxa loo mandla. Siye sahambisa i-120-kg yentsimbi yokuphosa nge njengoko-cast uburhabaxa bomphezulu Ra ≤ 6.3 µm-iqinisekiswe yi-Mitutoyo SJ-410 iprofilometers-kungekhona emva kokusila.
Ukuphumelela okukhulu kuxhomekeke kulawulo lweendleko zemitsi ephakathi. Umthengi eJamani udinga iiyunithi ezingama-420/ngonyaka ze-AMS 5387 zemilomo. Utyalo-mali lucatshulwe kwi-2,180 yeedola / iyunithi. Isisombululo sethu esichanekileyo sokuphosa isanti-sisebenzisa i-ceramic shell-coated cores kunye ne-automated mold assembly-ifike kwi-1,340 yeedola / iyunithi. Akukho kuthomalalisa kumandla okuqina (≥1,120 MPa) okanye ukuxhathisa kwe-corrosion intergranular nge-ASTM G28A.
Eyona nto uyifumanayo xa usebenzisana neFactory yokuCasa isanti echanekileyo
Ufumana uphononongo lobunjineli-hayi nje ukucaphula. Xa i-OEM yempompo yaseMntla Melika isithumelele ii-callouts ze-GD&T zezindlu zempompo yepiston entsha, iqela lethu labonisa imiba emibini enokubakho: okokuqala, unyamezelo lokwenyani oluchaziweyo kwizibuko le-12-mm-diameter laliqina kunokuphunyezwa ngokungqongqo kwephini elingundoqo; okwesibini, imfuneko yomphezulu wokugqiba kwi-fin yangaphakathi yokudlulisa ubushushu iphikisana nee-engile zokukhulula umngundo. Sicebise ngolwakhiwo olulolunye lwedatha kunye nohlengahlengiso lwee-engile eziyidrafti-ukunciphisa izinga lokulahlwa kwe-casting ukusuka kwi-18% eqikelelweyo ukuya kwi-0.7% yokwenyani ngaphezu kwe-14 yokuvelisa amaqashiso.
Ufumana isiqinisekiso sokuhanjiswa—hayi uqikelelo olunethemba. Ukuhamba kwethu okubhityileyo kubandakanya ukucwangciswa kwe-buffer-free yemisebenzi yendlela ebalulekileyo: umthamo wegumbi eliphambili, ixesha lomjikelo wesithando somlilo, kunye neendawo zokuhlola zeCMM zonke zimodelwa ngexesha lokwenyani. Kwiiodolo zeprototype, ixesha lokukhokela limiselwe kwiintsuku ezingama-28-akukho "kuxhomekeke kubukho bezinto eziphathekayo." Ukwenziwa kwemveliso, siqinisekisa ±2 iintsuku zekhalenda ekuthunyelweni okucwangcisiweyo-nokuba kunye nokulibaziseka kwesatifikethi semathiriyeli ekrwada.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge Umzi-mveliso weSanti echanekileyo kuba ukuchaneka yindlela esilinganisa ngayo impumelelo-hayi ukugqiba. Ikwi-0.008 mm ukuphindaphindwa kwenkqubo yethu yokubeka ibhokisi engundoqo. Kwilebhu eqinisekisiweyo ye-ISO 17025 eqinisekisa yonke i-carbon yobushushu elingana phambi kokugalelwa. Kwinyani yokuba i-91% yethu ye-cobalt alloy castings inqanawa ngaphandle kokuphinda isebenze-nangona isebenza kumda we-metallurgical feasibility.
Jonga phambili: umda olandelayo awunyamezeli ukunyamezela. Iinkqubo zomxube-ezifana nesanti ekufutshane-nemilo yesanti eneempawu ezidityanisiweyo zoomatshini ezakhelwe ngqo kumgodi wokungunda. Kulapho ukuphosa okuchanekileyo kuyeka ukuba yinyathelo lokuvelisa-kwaye ibe yinxalenye ye-DNA yecandelo elisebenzayo.
