Lapho onjiniyela becacisa ukulingwa kwensimbi kwama-hydraulic manifolds, izindlu zokumpompa, noma ama-winch shaft rollers, abagcini nje ngokuthenga insimbi—bathenga ukuqina kwe-dimensional ngaphansi kwengcindezi yamabha angu-300, ukungaguquguquki kwe-microstructural kuwo wonke amaqoqo anezingxenye ezingu-500, kanye nokungabekezeleli nhlobo ukuqina ezindaweni ezithwala imithwalo. Kungakho"imboni yokukhipha insimbi ngokwezifiso” akusona isigaba somthengisi—umkhawulo wokusebenza.
Sibone amaphrojekthi amaningi abambezeleka ngabasunguli abaphatha ukufakwa kwensimbi njengomsebenzi wempahla: ukubalwa kwamanodule e-graphite kuzitshiwe, izibonelelo ezinciphayo eziqagelwa kusukela kumidwebo yefa, amashejuli okwelashwa okushisa asetshenziswa ngokuvamile. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., konke ukubunjwa kwensimbi kuqala ngenjongo ye-metallurgical—hhayi nje ukugcwaliswa kwesikhunta. Indawo yethu ethobela i-ISO e-Qingdao iqhuba izinqubo zokuphonsa isihlabathi ezilinganiselwe ku-ASTM A48 Class 35, i-A536 ductile iron, kanye nemixube ye-ferritic-pearlitic yangokwezifiso—ngayinye ikhethiwe ukuze ifane namaphrofayela okucindezeleka okusebenzayo, hhayi nje amashadi wamandla aqinile.
Isidingo somhlaba wangempela silolonga isiyalo senqubo yethu. Ezindlini zamasilinda ephampu ye-piston, silawula amazinga okupholisa phakathi kuka-±2°C endaweni yonkana ukuze sinqande ukuhlanekezela ekuqondaneni kwe-bore. Kumarola we-winch centre shaft yemoto yobunjiniyela, siqinisekisa i-graphite morphology nge-SEM ngaphambi komshini—ngoba ukusatshalaliswa kwe-flake kuthinta ngokuqondile impilo yokukhathala ngezikhathi zomjikelezo ongu-12,000. Futhi uma amakhasimende ethumela i-GD&T callouts like ⌀0.015 mm ukubekezelela isikhundla kumabhore akhwezayo angu-8× Ø22 mm, asigcini nje ukulinganisa—silingisa ukunwetshwa okushisayo phakathi nomshini, bese silungisa ukulungisa kwamathuluzi ngesikhathi sangempela sisebenzisa ama-Renishaw QC20-W probe. Sibamba kanjalo-ke isikhundla sangempela phakathi kuka-0.008 mm ezindaweni zokukhiqiza.
Ukuhlanganiswa okuqondile kwenza lokhu kwenzeke—futhi kudingeke. Ukusakaza, ukwenziwa kwemishini ye-CNC, nokuqedwa kwangaphezulu kwenzeka ngaphansi kophahla olulodwa. Awekho ama-handoffs asho ukuthi akukho ukukhukhuleka okulinganayo phakathi kokuncipha kokukhipha kanye nokuqeda kokugcina. Sikhipha umshini ngokuqondile ezindaweni ezisakazwayo lapho kungenzeka khona, sisusa amaphutha okulungisa kabusha. Ukwelashwa kokushisa kulandela ukusakaza ngaphandle kokubambezeleka kokudlulisa—okubalulekile ekuzuzeni ubulukhuni be-Brinell obufanayo (220–260 HBW) kuzo zonke izingxenye zesigaba esiwugqinsi. Futhi ngenxa yokuthi sithola izinto zokusetshenziswa eziqinisekisiwe—okungalandeleka emibikweni yokuhlolwa komshini—siyazi ngokuqondile okuqukethwe kwesibabule kwenqwaba ngayinye ngaphambi kokuthela. Isibabule ngaphezu kuka-0.025%? Kwaliwe. Hhayi ngoba yephula i-spec-kodwa ngoba ibeka engcupheni ukushwabana okuncane phakathi kwezingxenye ezincane neziwugqinsi.
Umehluko wethu onamandla kakhulu awuwona umshini—ukusebenza kahle kohlelo lokusebenza. Lapho osebenza endaweni kawoyela eNyakatho Melika edinga izingxenye zephampu ye-cobalt alloy AMS 5387 eziklanywe kabusha zaba i-ductile iron ukuze zikwazi ukuzwela izindleko, asizange nje sishintshe izinto. Senze imodeli yamabhayisikili ashisayo ku-ANSYS, salungisa ama-nodularization agents ukuze sigcine ubude obungu-18% ku--20°C, kanye nokumelana nokugqokwa okuqinisekisiwe ngokumelene namajika okuguguleka kwe-API RP 14E. Umphumela: izindleko zeyunithi eziphansi ngama-40%, ukwehluleka kwenkundla okuyiziro ezinyangeni eziyi-18. Yilokho umehluko phakathi kokwenza insimbi nokuziphatha kwensimbi yobunjiniyela.
Uma uhlola a imboni yokukhipha insimbi ngokwezifiso, buza imibuzo emithathu: Bangakubonisa umbiko wakamuva we-CMM wengxenye enamadathamu abalulekile angu-≥5? Ingabe bagcina ukulandeleka okuphelele kwezinto ezibonakalayo—okuhlanganisa nezingodo zamakhemikhali e-ladle—kuwo wonke ama-oda? Futhi ingabe ithimba labo lonjiniyela lizohlaba umkhosi ukungqubuzana kwe-GD&T *ngaphambi* kokucaphuna—hhayi ngemva kokuhlolwa kwesihloko sokuqala? I-QINGDAO QIANGSENYUAN TECHNOLOGY iphendula ngoyebo—njalo. Ngoba ukwethembeka akulethwa esitsheni sokuthumela. Yakhelwe kukho konke ukuthululwa, wonke umjikelezo wokushisa, yonke i-micrometer yomshini olawulwayo.
