Lapho onjiniyela becacisa a i-pressure valve factory, abagcini nje ngokufuna i-hardware—bakhetha uzakwethu oyiqondayo impilo yokukhathala ngaphansi kwebha engu-350, ukuhamba ngebhayisikili elishisayo ezindaweni ezigcwele uwoyela, kanye neqiniso elingenakubekezelelwa lokukhukhuleka kwe-dimensional ekugxileni kwesihlalo sevalvu. Sibone amaphrojekthi amaningi ebambezelekile—hhayi ngamaphutha edizayini, kodwa ngenxa yesakhiwo sokusanhlamvu esingahambisani, imijikelezo yokwelashwa kokushisa engafani, noma ukuhunyushwa okungalungile kwe-GD&T ngesikhathi sokukhipha-kuya-machining handoff. Kungakho ukusebenzelana okuqondile nomkhiqizi ohlanganiswe mpo kubalulekile. Akuyona inkampani yokuhweba. Akuyena umthengisi onekhathalogi. A i-pressure valve factory elawula i-metallurgy, machining, kanye nokuhlolwa ngaphansi kophahla olulodwa olunesitifiketi se-ISO.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lolo hlobo lwesikhungo-esise-Qingdao, e-China, imigqa yokukhiqiza ilinganiselwe izingxenye lapho ±0.01 mm "ingaqini," akuxoxiswana ngayo. Ama-valve awo okucindezela awawona amayunithi ajwayelekile angaphandle kweshalofu. Akhiwe abe ama-assemblies asebenzayo: izindlu zesilinda sephampu ye-piston ezivala ibha engu-420, imibhobho ye-cobalt ye-cobalt ye-AMS 5387 imelana nokuguguleka kokugeleza kwe-slurry enesivinini esikhulu, amapulagi asekelwe ku-T800 asinda ekuchaweni komjikelezo ongu-650°C ezinhlelweni zokulawula imigodi. Lezi akuzona izicaciso zethiyori. Silinganise ubuqotho bendawo emizimbeni yabo yamavalvu eqediwe sisebenzisa i-interferometry yokukhanya okumhlophe—futhi saqinisekisa u-Ra ≤ 0.4 µm ebusweni obuvaleka kakhulu, ngisho nangemva kokuvala ingcindezi yokudambisa ingcindezi.
Yini ehlukanisa lokhu i-pressure valve factory kusuka kwabanye yindlela abasingatha ngayo ingxenye enzima kakhulu yenqubo: isixhumi esibonakalayo phakathi kokusakaza nokunemba kwemishini. Abahlinzeki abaningi bakhipha izinsiza noma ukwenza imishini—noma kokubili. Lokho kudala amaphuzu amathathu okuhluleka: izibonelelo zokuncipha ezingafani, i-microstructure engaqinisekisiwe njenge-cast, kanye nokuhlanekezela kwangemva komshini kusuka ekucindezelekeni okuyinsalela. I-QINGDAO QIANGSENYUAN yenza kokubili. Izindlu zabo ze-sand-cast iron zihlolwa nge-ultrasonic ngaphambi kokujika kwe-CNC. Izingxenye zabo ze-cobalt ezitshaliwe zihlolelwa i-X-ray *ngemuva* kokukhishwa kwegobolondo kodwa *ngaphambi* kokwelashwa kokushisa—ukubamba i-microporosity kusenesikhathi. Bese ukukhanda kwe-multi-axis kulandela ukulandelana okuqinile kwendlela yamathuluzi ukuze kuncishiswe ukwakheka okushisayo. Umphumela? Imizimba yevalvu ene-bore-to-flange perpendicularity egcinwe ngaphakathi kuka-0.015 mm ngaphezu kobude obungu-280 mm—iqinisekiswe nge-CMM, akulinganiselwa.
Abanye bangase baphikise ngokuthi abahlinzeki bendawo banikeza impendulo esheshayo noma ukuxhumana okulula. Iqiniso-ngama-valve ethusi alula, anengcindezi ephansi. Kodwa uma isicelo sakho sifuna ukuthotshelwa kwe-AMS 5387, izingodo ezincibilikayo ezilandelekayo, noma i-port geometry yangokwezifiso echezuka ku-ISO 4401, ukusebenziseka kalula kwesifunda kuba yisikweletu. Silandelele okuhlangenwe nakho kwe-OEM yaseNyakatho Melika: umphakeli wabo wangaphambili ulethe amaqoqo amane alandelanayo amavalvu ensimbi engenasici anokuqina okungahambisani (248–272 HB esikhundleni sokushiwo okungu-255–265 HB). Imbangela? I-annealing engapheli isikhathi sokucwiliswa kuwo wonke amashifu. I-QINGDAO QIANGSENYUAN ixazulula lokhu ngamaphrofayili okushisa abhaliwe, amashadi esithando somlilo aqondene nenqwaba, nokulandeleka okuphelele kwezinto—kusuka kusitifiketi se-ingot kuye kumbiko wokugcina wokuhlola. Ivalvu ngayinye iphethe i-ID eyingqayizivele exhunywe kumpahla yayo eluhlaza, irekhodi lokwelashwa kokushisa, kanye nedatha yokuskena ye-CMM.
Izinqumo ezisebenzayo ziqala ngokucacile—hhayi amakhathalogi. Uma uhlola a i-pressure valve factory, buza le mibuzo emithathu: Okokuqala, ingabe bangakunikeza imibiko yokuhlolwa komshini wokugaya * futhi* baqinisekise izici eziqinile endaweni yakho yokukhiqiza yangempela—hhayi nje isampula? Okwesibili, ingabe benza ukuhlola okusebenzayo (isb., ukuhlola ukuvuza kwebhamuza ku-1.5× ukucindezela kokusebenza) ku-100% wamavalvu aqediwe, noma ukuhlola indawo kuphela? Okwesithathu, siyini isilinganiso sabo sokugunyaza se-athikili yokuqala yamajiyometri angajwayelekile? Kwa-QINGDAO QIANGSENYUAN, impendulo ithi >94%—ngoba ukubuyekezwa konjiniyela kuqala ngaphambi kokucaphuna: Ukuqinisekiswa kwe-GD&T, impendulo yokwenziwa, kanye nokulingisa kokusakaza ngengozi yokuqinisa kujwayelekile, akuzona izengezo. Amandla abo awawona isikali-kuyisiyalo ekubulaweni kwe-alloy ephezulu. Futhi lowo umehluko phakathi kwengxenye elingana-naleyo eyenza.
