Uma onjiniyela becacisa ukufakwa kwensimbi empunga, abagcini ngoku-oda izingxenye ezithile—bazibophezela esisekelweni sokuzinza kobukhulu, ukuncibilika kokudlidliza, nokumelana nokugqokwa kwesikhathi eside ngaphansi kwemithwalo yomhlaba wangempela. A grey iron castings ifektri okufeza lezo zithembiso akuncikile ezicelweni ezibanzi. Izibonakalisa kusakhiwo esincane sakho konke ukuthululwa, ukuphindaphinda kwawo wonke umjikelezo womshini, kanye nokulandeleka ngemuva kwayo yonke inqwaba ephethwe ukushisa.
Ukunemba Kuqala Ngokuqiniswa Okulawulwayo-Hhayi Ukugcwaliswa Kwesikhunta Kuphela
Sibone amaphrojekthi amaningi kakhulu emiswa esivivinyweni sokuqala sokusebenza—hhayi ngenxa yamaphutha edizayini, kodwa ngenxa yokuthi ukusatshalaliswa kwe-graphite flake kokusakaza akufani ne-ASTM A48 Class 30B edingekayo yamandla noma iphrofayela yokuqina. Insimbi empunga ayiyona insimbi “elula”. Ukusebenza kwayo kuncike ekulawuleni okuqinile kokulingana kwekhabhoni (CE), izinga lokupholisa, isikhathi sokujova, kanye nokuqina kwesikhunta. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., konke ukukhishwa kwesihlabathi kuqala ngokuqinisekiswa kwe-spectrographic yekhemikhali ye-ladle—hhayi nje ukwakheka, kodwa amandla komoyampilo kanye namazinga e-titanium ayinsalela. Kungaleyo ndlela esihlala sibambe ngayo u-±0.15 mm kuma-bores abalulekile kumasilinda wepompo ye-piston, ngisho nasezindaweni eziwugqinsi ezisuka ku-12 mm kuya ku-65 mm.
Amakhasimende avame ukubuza: “Ingabe ungakwazi ukuphonsa imizimba yama-valve enezindonga ezincane ngaphandle kokushwabana kwe-porosity?” Yebo—kodwa kuphela lapho idizayini yokufaka isango iqinisekiswa ngesifaniso sokuqinisa i-MAGMAsoft *ngaphambi* kokugunyazwa kwephethini, nalapho amaphrinti ayisisekelo enziwa ukuthi amelane nokunyakaza ngesikhathi sokunyakaziswa. Asikuphathi ukulingisa njengebhokisi elimnyama. Senza imephu ama-thermal gradients ngesikhathi sangempela sisebenzisa ama-thermocouples ashumekiwe phakathi nokugijima kokufaneleka. Leyo datha ingena ngokuqondile ekusetheni kwethu i-CNC fixture—ngakho ukwenza imishini kunxephezela ukuncipha kokuqondisa okubikezelwayo, hhayi ukuqagela.
Ukuqina Kudinga Ukuhlanganiswa Okuqondile—Hhayi Ukulingisa Kuphela Noma Ukumachina Wedwa
Abanye abahlinzeki banikeza omashini bezinkampani zangaphandle ukulingisa. Lokho kudala izikhala: ubuqotho bendawo buyehla phakathi kokuqhuma kwesibhamu nokuphenduka kokugcina; ukuhlanekezela ukwelashwa kokushisa akukalwa kuze kube sekuhlolweni kokugcina; Ama-callout e-GD&T afana nokubekezelela indawo Ø0.05 mm ngokuhlobene nedatha elilingi awakwazi ukubamba. Esikhungweni sethu esithobela i-ISO e-Qingdao, izinsimbi ezimpunga zihamba ngaphandle komthungo zisuka ekuthatheni ziye kuma-multi-axis CNC—akukho ukudluliselwa kwangaphandle, akukho kulungiswa kabusha, akukho ukulahleka kokuqhubeka kwedatha.
Lokhu kuhlanganiswa kuletha imiphumela elinganisekayo:
- Ukuqedwa kobuso ezihlalweni zamavalvu odonsa amanzi abanjwe ku-Ra 0.8 µm—ngaphandle kokujikijelwa kwesibili—ngoba ukwenza imishini kulandela emahoreni angama-24 okudambisa ingcindezi.
- Ukungaguquguquki kokuqina okuncane kuzo zonke izindonga ezibhorekile (210–230 HBW) kuqinisekiswe ukuhlolwa kwe-Rockwell B *ngemuva* kokwelashwa kokushisa kokugcina, hhayi ngaphambi
- Ukulandeleka okugcwele: Ingxenye ngayinye iphethe i-ID ye-laser-etched lot exhuma emuva ekuhlaziyweni kokuncibilika, idethi yokukhipha, ijika lokwelapha ukushisa, kanye nombiko we-CMM
Kungakho amaroli e-winch centre yewintshi yemoto yobunjiniyela—kuncike ekugobeni komjikelezo nokuxhumana okulimazayo—ehlala edlula impilo yenkambu yamahora angu-12,000 ekusetshenzisweni kwe-OEM yase-Europe. Ukuqina akwengezwa kamuva. Yakhelwe kuhlelo lokusebenza.
Ukwethenjwa Kutholwa Ngokungafihli—Hhayi Izitifiketi Odongeni
“Isitifiketi se-ISO” sisho okuncane uma izitifiketi zempahla engenayo zingahlolisiswa ngemibiko yokuhlolwa komshini—noma uma ukuhlolwa kobukhulu kwenzeka kuphela esigabeni sokugcina. Siqinisekisa ukuthobelana kwezinto ezingavuthiwe *ngaphambi* kokuncibilika: ukuhlaziya okubonakalayo kwe-pig iron, izilinganiso zokushaja okulahliwe, kanye nezengezo ze-ferroalloy zifakiwe futhi ziyagcinwa. Yonke insimbi empunga idlula ezindaweni ezintathu zokuhlola eziyisibopho:
- Ukuqinisekiswa kwezinto ezingenayo (isampula ye-spectral + eqinile ngokushisa ngakunye)
- Ukuskena kwe-CMM okungaphakathi kwenqubo kwama-datum abalulekile ngemva komshini onzima
- Isilinganiso sokugcina sokubonwa kwezindawo zokuvala kusetshenziswa amasistimu okubona wokuxazulula i-5-micron
Akukho okuhlukile—ngisho nama-prototypes. Umkhiqizi wephampu waseNyakatho Melika uthole lokhu ngesikhathi sokuhleleka kwabo kwesibili: umdwebo wabo obuyekeziwe wawuhlanganisa ne-specness eqinile yokucaba ku-flange ekhuphukayo. Ithimba lethu liyihlabe umkhosi ngesikhathi sokubuyekezwa konjiniyela—hhayi ngokwenqatshwa, kodwa ngesiphakamiso sokwenziwa: ukushintsha idatha yokusakaza ukuze kuncishiswe ukuchezuka okubangelwa ukulungisa. Bakugunyaza. Izinga lokwamukelwa kwe-athikili yokuqala leqe lisuka ku-68% laya ku-100%.
Kungani Onjiniyela Bomhlaba Babuyela Kule Factory Yensimbi Empunga
Akukhona mayelana nenani eliphansi. Kumayelana nokuqeda ubungozi obufihliwe—uhlobo oluvela ngesikhathi sokuhlolwa kwe-FAT noma, okubi nakakhulu, ensimini. Uma iveluvu yakho yokucindezela kufanele ivaleke kubha engu-350 iminyaka engu-20, noma isisekelo sakho sephampu simelana namaza azwakalayo afika ku-1,200 Hz, ukuqagela kubiza ngaphezu kokunemba.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lapho i-metallurgy ihlangana khona nobunjiniyela: izinqubo zokusakaza ezilungiselwe indawo yesevisi ethile, amasu okwenza imishini aqondaniswe ne-graphite morphology, namaphrothokholi ekhwalithi adizayinelwe ukuziphendulela okubalulekile komgomo. Sinikeza isevisi amakhasimende adinga insimbi empunga esebenza kahle—hhayi nje ukufika.
Uma sibheka phambili, ukugxila kwethu kwe-R&D kusasele ekuthuthukisweni kwe-hybrid casting-machining: ukunciphisa isikhathi sokuhola esiphelele sezindlu eziyinkimbinkimbi ngaphandle kokudela ubuqotho besakhiwo esincane. Ngoba ukuqina akukalwa ngeminyaka yodwa. Kukalwa ngokuzethemba—ngaso sonke isikhathi lapho isistimu inamandla.
