Lapho onjiniyela bayacacisa i-steel casting foundry ozakwethu bamavalvu abalulekile ka-hydraulic, amaphampu, noma amawintshi asogwini, abadingi nje insimbi ethelwe esibunjeni. Badinga ukuphindaphinda kobukhulu ngaphansi kokubekezelela okungu-0.02 mm. Ukungaguquguquki kwe-Microstructure kuwo wonke amaqoqo angama-500-kg. Izimanga eziyiziro ekuphenduleni kokwelashwa kokushisa. Nokulandeleka okugcwele—kusuka ku-AMS 5387 cobalt alloy ingot certification kuya embikweni wokugcina we-CMM.
Sibone amaphrojekthi amaningi kakhulu elibaziseka ngabasunguli abaphatha ukufakwa kwensimbi njengenqubo yempahla. I-OEM eyodwa yaseNyakatho Melika ilahlekelwe izinyanga ezintathu iqinisekisa indlu yesilinda yephampu yepiston ngenxa yokuthi imodeli yokuncipha kwesihlabathi somphakeli ayizange ihambisane nokuhlanekezela kwangempela kwangemva komshini. Enye i-European hydraulics firm ilahle u-17% wokukhiqiza kwayo kokuqala ngemuva kwe-porosity yendawo-engabonwa ngesikhathi sokuhlolwa okubonakalayo-okubangele ukuvuza kwengcindezi ku-420 bar. Lawa akuwona amacala. Ziyizimpawu zamandla ahlukene: ukubunjwa kwenziwa esitolo esisodwa, ukwenziwa komshini kwesinye, insimbi kukhishwa ingxenye yesithathu.
Kungakho imikhakha eshayelwa ukunemba manje ibeka phambili ukuhlanganiswa okuqondile i-steel casting foundry imisebenzi—hhayi nje ukulawula izindleko, kodwa ukubikezela kwezinga le-physics. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke insimbi nensimbi engagqwali iqala ngokukhethwa kwezinto okugunyazwe ngokumelene ne-ASTM A958, EN 10213, noma izimfuneko ezishiwo yikhasimende eziqinile/umthelela. Akukho okushintshiwe okuvamile kwe-“316 stainless”. Uma umdwebo wakho udinga i-UNS S32750 super duplex enobuncane obungama-45 HRC ngemva kokuhlanganisa isixazululo, amalogi abo esithandweni somlilo kanye nemibiko yokuqina kwemephu kubonisa lokho kanye—hhayi isitembu sokudlula/sokwehluleka eshidini lenqwaba.
Indawo yabo ethobela i-ISO iphatha kokubili ukutshalwa kwezimali kanye nokusakazwa kwesihlabathi—kodwa kuphela lapho indlela ngayinye iletha inzuzo elinganisekayo. Ukufakwa kwe-investimenti ye-cobalt alloy nozzles enezindonga ezincane edinga ukulawulwa kodonga oluyi-±0.05 mm. Ukufakwa kwesihlabathi kwamarola we-winch centre shaft yemoto yobunjiniyela enobubanzi obukhulu, lapho amazinga okupholisa alawulwayo avimbela ukuqhekeka okuncane kuma-alloys asekelwe ku-T800. Ngokusobala, ukwenza imishini akuyona into ecatshangelwayo. Amaseli awo e-CNC anemigqa eminingi ahlala amamitha ukusuka endaweni yokuphonsa. Lokho kusondela kunika amandla ukukhululeka kwengcindezi yangemva kokusakazwa ngaphambi komshini onzima—kanye nempendulo yesikhathi sangempela phakathi kwama-foundry metallurgists nabahleli bezinhlelo be-NC lapho ikhasi le-warpage lidlula amamodeli aqageliwe.
Nakhu okuwahlukanisa nama-broad-spectrum foundries:
- Isiyalo se-alloy, hhayi ukuhlukahluka kwe-alloy. Abafuni ubungcweti emabangeni angama-27 asuselwa ku-nickel. Bayingcweti kwe-AMS 5387, T800, ne-UNS R30003—ikakhulukazi ezingxenyeni zephampu ezinomfutho ophezulu lapho ukuhlukaniswa kwe-carbide kuba nomthelela ngqo empilweni yokukhathala. Izinqubo zabo zokwelashwa kokushisa zihlanganisa amajika ahamba kancane apholile aqinisekisiwe engxenyeni yangempela yejometri, hhayi nje amakhuphoni.
- I-GD&T-first production. Uma uthumela umdwebo onokubekezelela indawo ku-Ø12 mm bores ngokuhlobene nendiza yedatha, isibuyekezo sabo sobunjiniyela simaka ukuthikamezeka okungaba khona kwe-fixation *ngaphambi* kokugunyazwa kwephethini—hhayi ngemva kokwehluleka ukuhlolwa kwe-athikili yokuqala. Benza imephu yonke i-callout ye-GD&T ebalulekile endleleni ethile yokuhlola ye-CMM, ukusethwa kokulinganisa kokubona, noma ukulungiswa kokuhlola okusebenzayo.
- Ayikho ikhwalithi "yebhokisi elimnyama". Yonke imikhumbi yensimbi esakazwa ngensimbi enedosi yedijithali: imibiko yokuhlola impahla eluhlaza, ukuhlaziywa kwe-spectrographic ngokuncibilika ngakunye, amashadi omjikelezo oshisayo, idatha yokuhlola enobukhulu (i-CMM + optical), kanye nezilinganiso zokuqedwa kwe-Ra/Rz. Hhayi izifinyezo. Amafayela angahluziwe. Ilandeleka enombolweni yokushisa, i-ID yomsebenzisi, nenombolo yomkhiqizo womshini.
Abanye bangase baphikise ngokuthi izisekelo zesifunda zinikeza ukuguqulwa okusheshayo. Kodwa isivinini ngaphandle kokubikezela kubiza ngaphezulu. Isikhathi sokuhola esisheshayo samaviki angu-4 asisho lutho uma iqoqo lesibili lidinga ukusetshenzwa kabusha ngenxa yokubala kwamaqhuqhuva e-graphite okungahambisani nokusakazwa kwensimbi eyi-ductile—noma uma okuqukethwe kwe-ferrite yensimbi engagqwali kukhukhuleka ngaphandle kwebanga elingu-3–12%, okonakalise ukumelana nokugqwala kusevisi yegesi emuncu. Ukugeleza komsebenzi okunciphile kwe-QINGDAO QIANGSENYUAN akudela izinyathelo zokuqinisekisa; kuzilandelanisa ukuvimbela ukusebenza kabusha. Izinto ezingenayo ziyaqinisekiswa *ngaphambi* kokulungiswa kwesikhunta. Ubukhulu obubalulekile buyahlolwa *ngemuva* kokukhululeka kwengcindezi kodwa *ngaphambi* kokuqina kokugcina. Ukuhlola okusebenzayo kwenzeka *ngemuva* kokuqedwa kwendawo—hhayi njengesango lokugcina.
Okwamaqembu okuthenga ahlola a i-steel casting foundry, buza imibuzo emithathu: Bangakubonisa umbiko we-CMM wengxenye efanayo ku-geometry, ingxubevange, nekilasi lokubekezelelana nelakho? Ingabe baphethe izitifiketi zamanje zezimakethe oziqondise—i-ASME BPVC Isigaba II sezingxenye zokucindezela, i-API 6A yemishini yase-oilfield, noma i-PED 2014/68/EU? Futhi okubaluleke kakhulu: Ingabe ithimba labo lonjiniyela lizosayina ngokubambisana amanothi okwenziwa komdwebo wakho—okuhlanganisa irediya ephakanyisiwe, ama-engeli angakapheli, noma ukuguqulwa kwesango—ngesizathu esibhaliwe?
Lelo phuzu lokugcina libalulekile ngoba amaphutha okulingisa awavamile ukuvela lapho kuthululwa khona. Baqala esikhaleni se-design-for-manufacturing. Abaphathi bephrojekthi ye-QINGDAO QIANGSENYUAN abacaphuni nje imidwebo—bayayichasisa. Bazomaka irediyasi engu-0.3 mm ekhoneni elinengcindezi ephezulu njengokunganele kumkhuba wokudabula oshisayo we-AMS 5387. Bazoncoma ukuthi ushintshe indawo yokuphrinta ewumongo ukuze ugweme ukugijima kabi esigabeni sogqinsi esingu-120 mm. Lokhu akuyona i-fluff yokweluleka. Kubhalwe phansi ukuncishiswa kwengozi okuxhaswe iminyaka eyi-14 yokukhiqizwa kwengxenye ye-hydraulic system yonkana eNyakatho Melika, eYurophu, naseNingizimu-mpumalanga ye-Asia.
Uma ubheka phambili, isidingo sezinqubo ezixubile—lapho ukusakaza komumo oseduze nenetha kuhlangabezana nokunemba kwemishini ekhiphayo—ngeke kwehle ijubane. Izindlu zamaphampu esizukulwaneni esilandelayo zidinga izindlela zokugeleza zangaphakathi okungenakwenzeka ukuzisakaza ngokuhlanzekile, nokho eziyinkimbinkimbi kakhulu ekujikeni okujwayelekile. Ikusasa ngelikazakwethu abaphatha ukulingisa nokwenza imishini njengezinkinga zefiziksi ezincikene, hhayi izikhungo zezindleko ezilandelanayo. Ukugxila kwe-R&D kwe-QINGDAO QIANGSENYUAN ekulingiseni imodeli yokusebenzisana okushisayo kubonisa lelo qiniso. Umgomo wabo olandelayo wokuqinisekisa isitifiketi uhlose i-NADCAP AC7114 yokuhlola okungabhubhisi—ngoba izingxenye zensimbi ezinengxubevange ephezulu ezisebenza ku-500°C kanye nebha engu-700, “akukho sici esibonakalayo” akwanele. Udinga idatha yesigaba esicacisiwe ye-ultrasonic attenuation.
Uma uhlelo lwakho lokusebenza ludinga ukungabikho ebucayini ekuthembekeni kwesakhiwo, ukwethembeka kobukhulu, noma ukulandeleka kwezinto—khona ke ilungelo i-steel casting foundry akuyena umbhidi oshibhe kakhulu. Yileso imibhalo yenqubo yayo efundeka njengencwadi yefiziksi, imibiko yayo yokuhlola efana nezincwadi zaselabhu, futhi onjiniyela bayo bakhuluma ulimi lwakho lwe-GD&T kahle. Lokho kunemba akwenzeki ngengozi. Yakhiwe—inqwaba ngemva kwenqwaba, ingxenye ngemva kwengxenye.
