Lapho onjiniyela bayacacisa 17-4 ukutshala izimali kumavalvu we-hydraulic hydraulic high-pressure or turbine pump housings, abagcini nje ngokukhetha into ethile-babheja ngokuzinza kwe-dimensional, ukumelana nokugqwala, nokuvumelana kwe-microstructural ngaphansi kokuhamba ngebhayisikili okushisayo. Yingakho ukhetha okulungile 17 4 imboni yokutshala izimali kubaluleke ngaphezu kokucaphuna inani kuphela. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye sasakaza izingxenye ezingaphezu kwezingu-2,300 ezihlukile ze-17-4 PH kusukela ngo-2019—ngasinye sidinga ukulawula okuqinile kwe-GD&T, ukulandeleka okugcwele kokwelashwa kokushisa, kanye nokungabi nazihibe ekuthobeni kwe-AMS 5643.
Kungani i-17-4 PH Idinga Okungaphezulu Kokusakaza Okujwayelekile Kokutshalwa Kwezimali
17-4 PH insimbi engagqwali “akuyona nje enye into engenasici.” Ukuziphatha kwayo kokuqinisa imvula kusho zonke izinyathelo—kusuka kuphethini ye-wax yejiyomethri kuya emjikelezweni wokugcina wokuguga—kuthinta ngokuqondile amandla esivuno, impilo yokukhathala, namandla okwenza izinto. Sibone amakhasimende ehluleka ukwenza i-prototype ngenxa yokuthi abahlinzeki bawo basebenzisa amagobolondo ajwayelekile adizayinelwe okungu-316, hhayi izinga eliphezulu lokunwetshwa kwe-thermal kanye nezinga lokuqina lokuqina elingu-17-4 PH. Umphumela? Ukuncipha okuncane emizimbeni yamavalvu anodonga oluncane, i-HRC 38–42 engaphandle kwe-spec ngemuva kokuguga kwe-H900, noma ukuqhekeka kwendawo ngesikhathi sokukhululeka kwengcindezi yangemva kokuphonswa.
Isizinda sethu esiqinisekisiwe se-ISO 9001 sibhekana nalokhu ngezivikelo ezintathu ezakhelwe ngaphakathi: Okokuqala, ukwakheka kwamagobolondo e-ceramic ngokwezifiso alungiselwe izinga lokushisa elingu-17-4's 1450°C. Okwesibili, amarampu okupholisa alawulwayo ngaphakathi kweziko zokudonsa ezisizwa nge-vacuum—akukho ukucisha komoya okuzungezile. Okwesithathu, ukuqinisekiswa kwe-CMM okuphoqelekile kwangemva kokwelashwa kumadatha abalulekile ngaphambi kokuqala komshini. Sibamba kanjalo ±0.05 mm kumadayamitha angu-300 mm ngaphandle kokugaya okwesibili.
Ukuhlanganisa Okuqondile Kuxazulula Amaphuzu Obuhlungu Okukhiqiza Kwangempela
Abathengi abaningi baphatha i-casting kanye ne-CNC njengabathengisi abahlukene. Lokho kudala izikhala ze-handoff: izikimu ze-datum ezingaqondile, izibonelelo zesitoko ezingakhulunyelwanga, noma impendulo ebambezelekile mayelana noshintsho lokuqina kodonga. Esikhungweni sethu se-Qingdao, ithimba lonjiniyela elifanayo liphethe uchungechunge oluphelele—kusuka ekwakhiweni kwesikhunta sokutshala imali kuya ekugxileni kokugcina.
- Sisebenza ngomshini wonke ama-castings angu-17-4 endlini sisebenzisa i-5-axis DMG MORI NTX 1000s, siqeda ukungafani kwesistimu yokuxhumanisa abadayisi.
- I-metallurgists yethu isayinda ngokubambisana amashadi okuphatha ukushisa ngezitifiketi zempahla eluhlaza—zonke iqoqo lilandelela emuva kusitoko esiqinisekisiwe sebha ye-SAE AMS 5604
- Ukuqedwa kobuso akulokothi kube umcabango osemuva: I-Ra 0.8 µm iyindinganiso ebusweni bokuvala; I-Ra 0.4 µm itholakala nge-electropolish—iqinisekiswe nge-profilometer, hhayi isilinganiso esibonakalayo
Lokhu kuhlanganiswa kunciphisa isikhathi sokuhola ngo-37% kuma-oda wevolumu emaphakathi (ama-50–500 ama-pcs) futhi kuqede ukusebenza kabusha ekuqageleni kwenqubo okungafani. Ipompo eyodwa ye-OEM yaseNyakatho Melika yehlise ukwehluleka kwenkundla ngo-92% ngemva kokushintsha isuka kumodeli yomhlinzeki wezigaba ezimbili iye kusixazululo sethu somthombo owodwa ongu-17-4 PH.
Lokho Amakhasimende Akubuza Empeleni Ngaphambi Kokwenza I-oda Lawo Lokuqala
"Ungakwazi ukusakaza iziteshi zokupholisa zangaphakathi ngaphansi kobubanzi obungu-2.5 mm?" Yebo-sikhiqize izimbobo eziyimpumputhe ezingu-1.8 mm ezindlini zamasilinda angu-17-4 sisebenzisa amasu alahlekile aqinisekiswe i-CT scan yezimboni.
"Ingabe uyayisekela i-H1150M + ukuguga kabili ukuze uthole ukuqina okuphezulu kakhulu?" Yebo—izingodo zethu zomlilo zirekhoda amanani werempu, izikhathi zokucwiliswa emanzini, namaphrofayili okupholisa ingxenye ngayinye, anamasiginesha edijithali avela ku-QA nemikhondo ye-metallurgy.
"Ingakanani i-oda lakho elincane lejometri engajwayelekile?" Ayikho i-MOQ elungisiwe. Senza ama-prototypes ezihlahleni zamagobolondo okwabelwana ngazo uma kungenzeka—futhi sabelane ngezindleko zamathuluzi ngokusobala. Kodwa ngeke sicaphune uma ukujiya kodonga kwehla ngaphansi kuka-4.2 mm noma ama-engeli asalungiswa ehla ngaphansi kuka-1.5°. Leyo mikhawulo ayigodli; zisekelwe ekuhloleni okuhlulekile kwesihloko sokuqala okungu-127 okufakwe kusizindalwazi sethu sangaphakathi se-NCMR.
Siphendula le mibuzo kusengaphambili—hhayi ocingweni lokuthengisa, kodwa embikweni wethu wokubuyekezwa konjiniyela, olethwe phakathi namahora angu-72 omdwebo othunyelwe.
Ukubheka Phambili: Lapho Ukulingisa Okunembile Kuzolandela Khona
Umngcele olandelayo awuzona izingxenye ezinkulu—uyizixhumanisi ezihlakaniphile. Manje sishumeka izici ezincane ngokuqondile ekulingweni kokutshalwa kwezimali okungu-17-4: izinombolo zesiriyeli ezifakwe nge-laser ezifundeka ngemva kokudutshulwa, imisele ehlanganisiwe yokuqinisekisa indlela epholile, kanye nezindawo zedatha eziklanywe kusengaphambili ukuze zibe ±0.015 mm ngaphambi kwe-CNC yokugcina. Lokhu kuqeda izinyathelo zokumaka ngemuva kokulingisa futhi kunciphisa izindawo zokuthintwa zokuhlola ngo-60%.
Ukugxila kwethu kwe-R&D kuhlala kukuncane futhi kujulile: ukwenza kahle izinqubo eziyingxube lapho ukufakwa kwe-investimenti kulethe isimo esiseduze, kanye nokwenza imishini enembayo kwengeza izindawo zokusebenza lapho kudingeka khona. Awekho ama-alloys “alingana-owodwa”. Awekho amakhambi okushisa angekho eshalofini. Ukusebenza okuphindaphindwayo, okubhaliwe, okufundekayo okungu-17-4 PH—kulethwe kokukodwa 17 4 imboni yokutshala izimali ku-Qingdao ephatha ishidi lakho njengenkontileka, hhayi isiphakamiso.
