Xa iinjineli zicacisa ukuphosa i-gravity die cast for high-precision metal parts, abakhethi nje inkqubo-bakhetha iqabane elikwazi ukubamba ukunyamezela kwe-± 0.05 mm kwi-cobalt alloy pump housings ngelixa igcina ingqibelelo ye-microstructural phantsi kwe-350 bar yoxinzelelo lokusebenza. Elo nqanaba lokungaguquguquki lahlula a umxhuzulane die bephosa umenzi mveliso ukusuka kwindawo yorhwebo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza loo mida imxinwa yonke imihla. Ngokusekelwe eQingdao, eChina, inkampani ihambisa amacandelo okuphosa okusebenzayo apho ukungaphumeleli akunakho ukhetho: izindlu ze-piston pump cylinder ze-hydraulic systems, i-shaft rollers yeziko le-winch yemoto yobunjineli, i-AMS 5387 cobalt alloy 6 iipompo zezixhobo zenkonzo yeoli. Ezi ayizoprototypes okanye enye-off. Ziinxalenye zemveliso ezinokulandeleka okupheleleyo kwezinto, iirekhodi zonyango lobushushu, kunye nokuthotyelwa kwe-GD & T eqinisekisiweyo ye-CMM-ithunyelwe kwii-OEMs kulo lonke elaseMntla Melika, iYurophu, kunye ne-Asia-mpuma ye-Asia.
Yintoni eyenza ukuba amandla abo omxhuzulane afe ahluke ayisosixhobo kuphela-yindlela abaphatha ngayo isinyithi njengento yoyilo. Ababoneleli abaninzi bafumana iingots ezisele zifakwe ngaphambili kwaye bagalele ngokungaboniyo. I-QINGDAO QIANGSENYUAN isebenzisana ngokuthe ngqo kunye nabanikezeli bezinto eziqinisekisiweyo ukuze kuqinisekiswe amandla okuqina okuthe ngqo kwibhetshi, ukuhanjiswa kobungakanani beenkozo, kunye nokusasazwa kwe-carbide * phambi kokulungiswa kobumba. Kwii-alloys ezisekelwe kwi-cobalt T800, oko kuthetha ukuba ukuqina kokuqina kuhlala ngaphakathi kwe-42-46 HRC emva kokuxutywa kwesisombululo-kwaye kuqinisekiswe kwakhona emva komatshini. Siye sabona abathengi betshintsha ukusuka kubanikezeli bemigangatho emithathu ukuya ngqo kunxibelelwano emva kokufumanisa ulwahlulo olungahambelaniyo lwe-interdendritic kukhuphiswano olukhuphisanayo lubangele ukhukuliseko lombhobho kwangaphambi kwexesha kwiindlela zolwelo zesantya esiphezulu.
Ukuhamba kwabo okudityanisiweyo ngokuthe nkqo kuphelisa iimpazamo ze-handoff ezithoba ukuchaneka. Umxhuzulane die casting kwenzeka ISO-ithobela bays kunye preheat ngundo elawulwayo (220-260 ° C), ilinganiswe iifestile ubushushu kugalelwa (± 5 ° C), kunye real-time esweni thermal ngexesha lokuqina. Akukho kuphinda kunyibilike okwesibini. Akukho mashini ngaphandle kwendawo. Imisebenzi ye-CNC ilandela ngokukhawuleza-kumatshini we-5-axis ekwazi ukujikeleza iziteshi zokupholisa zangaphakathi ngaphakathi kwezindlu ze-cylinder ezingama-40 mm ngelixa ubambe indawo yokwenene ngaphakathi kwe-0.015 mm. Unyango lobushushu ludibanisa ngaphakathi: isisombululo se-anneal, ukucima, kunye nokuguga kwenzeka ngaphandle kokufuduswa kwenxalenye. Ukugqitywa komphezulu-ukucoca i-electropolishing, ukudubula ukuchama, okanye ukugquma kwe-HVOF-kucacisiwe ngokwemfuno yokusebenza, hayi ukhetho lwekhathalogu.
- Iivalve zoxinzelelo: Ifakwe kwi-ASTM A494 M35-1, ifakwe kwi-API 6D Class Class 600 specs, ukuvuza-kuvavanywa kwi-1.5× uxinzelelo lokusebenza
- Impompo iziseko: Izindlu zentsimbi ye-Sand-cast kunye ne-lugs edibeneyo yokukhwela, iyancipha uxinzelelo ngaphambi kokugaya okokugqibela
- Imilomo yengxubevange yeCobalt: I-AMS 5387 imathiriyeli, uburhabaxa bomphezulu we-Ra ≤ 3.2 µm, akukho kugaya okwesibini kuyadingeka
- I-winch shafts engekho-standard: I-T800 ialloy, i-100% ihlolwe i-ultrasonic, ukuzinza kwe-dimensional kuqinisekisiwe emva kweeyure ezingama-72 zokusingqongileyo
Abanye banokuxoxa ukuba ukufakwa kotyalo-mali kunikezela ngeenkcukacha ezithe kratya kwiijometri ezinzima. Kodwa ukuphoswa komxhuzulane kuzisa iipropathi ezigqwesileyo zobuchwephesha-ubuninzi obuphezulu, i-porosity esezantsi, kunye namandla aphindaphindwayo okuqina-okubaluleke kakhulu xa iinxalenye zijikeleza phakathi kwe-20 ° C yokuqalisa kunye ne-180 ° C yokusebenza kwexesha. Silinganise ukuphuculwa kobomi bokudinwa kwama-37% kumzimba wevalve yealloyi ye-cobalt ye-gravity-die-cast xa kuthelekiswa nokulingana notyalo-mali phantsi kweeprofayili ezifanayo zomthwalo wokutyhutyha. Umehluko? Ukulawulwa kokuqina kolwalathiso kunye nokunciphisa imingxunya encitshisiweyo kufutshane nemimandla yoxinzelelo olubalulekileyo.
Ukuthembeka konikezelo kuvela kucwangciso oluqeqeshekileyo—kungekhona izithembiso. Ukuhamba komsebenzi wabo obhityileyo kusebenzisa i-takt yemephu yexesha losapho ngalunye lwamalungu: iiyure ezili-18 zokuvelisa iplagi ye-cobalt alloy (kubandakanywa ne-NDT), iiyure ze-32 zezindlu zempompo zensimbi engenasici (ngonyango lobushushu kunye nokuhlolwa kokugqibela). Amaxesha okukhokelela kwiprototype aqala kwiintsuku ze-12 zokusebenza-kungekhona iintsuku zekhalenda-kunye nengxelo yobunjineli malunga nokwenziwa kwezinto ezikhutshwe kwiiyure ezingama-48 zokungeniswa komzobo. Utoliko lwe-GD&T alukhutshelwanga ngaphandle; Iqela labo le-metrology liqinisekisa ubume bedatha ngokuchasene neemfuno zendibano esebenzayo ngaphambi kokukhutshwa kwesixhobo.
A umxhuzulane die bephosa umenzi mveliso ufumana ukuthenjwa ngobungqina obubhaliweyo—kungekhona ngeencwadana ezinemifanekiso. Yonke impahla ethunyelwayo ibandakanya isatifikethi sokuthobelana esidwelisa amanani obushushu, ii-ID zeqashiso, iingxelo zokuhlolwa kwe-dimensional (CMM + optical comparator), kunye neerekhodi zovavanyo ezingonakalisi. Xa impompo ye-OEM yaseYurophu ifuna ukulandelelwa ngokupheleleyo umva kwimvelaphi ekrwada yokuthotyelwa kwe-ASME yeCandelo VIII, i-QINGDAO QIANGSENYUAN ibonelele ngezishwankathelo zophicotho lomthengisi kunye neengxelo zovavanyo lokusila kwiiyure ezingama-72-akukho kuphinda-phinda, akukho kulibaziseka.
Ukujonga phambili, ujoliso lwabo lwe-R&D lujolise kwiinkqubo ezixubileyo: ukudibanisa ubunzima bokuphosa ingqibelelo yesakhiwo kunye ne-CNC yokugaya indawo yokutywina efuna ukucaba kwe-sub-micron. Ukwandiswa kwesiqinisekiso kubandakanya i-AS9100 yamacandelo e-cobalt ye-aerospace-grade kunye ne-ISO 13485 yeenkqubo zokuphatha ulwelo lwezonyango. Kodwa eyona nto iphambili ayitshintshanga—iindawo ezichanekileyo eziphoswayo zisebenza, hayi ukufika nje. Ngenxa yokuba kwii-hydraulics ezinoxinzelelo oluphezulu, iivalvu ezikude nonxweme, okanye kwiinkqubo ze-winch ezinzima, ukuchaneka komgangatho ngaphandle kokuthembeka kokusebenza yi-scrap nje ebiza kakhulu.
