Isevisi yokukhipha insimbi ayikona nje ukuthela insimbi encibilikisiwe esikhunjeni. Imayelana nokubamba ukubekezelelana kobukhulu phakathi kuka-±0.05 mm endaweni yephampu yensimbi engu-300-mm kuyilapho uqinisekisa ukufana kwesakhiwo esincane kuwo wonke amaqoqo angu-120-kg—ngaphansi kwengcindezi, ngaphansi kokuguga, ngaphansi kocwaningo. Leso isisekelo esisebenza kuso kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.—hhayi njengomthengisi, kodwa njengozakwethu wenqubo oshumekwe emijikelezweni yokuklama isistimu ye-hydraulic, ukuqinisekiswa kwemishini ye-oilfield, nemigqa yokuhlanganisa iwintshi yemoto yobunjiniyela.
Kungani Isevisi Yokusakaza Insimbi Yehluleka Lapho Ukunemba Kungakhiwe Ngaphakathi
Sibone izindlela ezintathu zokuhluleka eziphindelelayo-hhayi kusukela ekusetshenzisweni okungekuhle kwesisekelo, kodwa kusukela ekulindelweni okungalungile. Okokuqala: ukucabangela "insimbi empunga" kusho into eyodwa. Ayikwenzi. I-ASTM A48 Ikilasi 30B, EN-GJL-250, kanye ne-ISO 185-200 ngayinye isabela ngendlela ehlukile ekubhayisikilini okushisayo ngesikhathi somshini—futhi eyodwa kuphela eletha umthamo wokudambisa odingekayo ezindlini zamasilinda wepompo ye-piston ezisebenza kubha engu-350. Okwesibili: ukuphatha ukulingisa njengesinyathelo esizimele. Eqinisweni, izingxenye ze-sand-cast iron ezihloselwe ukuqedwa kwe-CNC zidinga ama-engeli asalungiswa, izibonelelo zesango, nokubekwa kwesikhuphukeli esithinta ngokuqondile ukuhlanekezela kwangemva komshini. Sake salungisa kabusha imizimba yama-valve engu-17 ngenxa yokuthi iphethini yasekuqaleni ayizange ibale i-anisotropy yokuncipha ku-high-phosphorus grey iron—ebiza izinsuku ezingu-11 kanye no-$8,400 we-scrap kanye nokulinganiswa kabusha. Okwesithathu: ukweqa ukulandeleka kwe-metallurgical. Elinye ikhasimende laseYurophu linqabe ukuthunyelwa okugcwele—hhayi ngobukhulu, kodwa ngenxa yokuthi ilogi ye-ladle ibingenakho ukuxhunywa kwenombolo yokushisa emibikweni yokuhlola okuqinile. Manje simaka konke ukuthululwa ngamakhadi enqwaba anekhodi ye-QR aboshelwe kokuphumayo kwe-spectrometer, amajika wesilinganiso sokupholisa, kanye nedatha yokwenza imephu yokuqina.
Lapho Isevisi Yokuphonsa Insimbi Ihlangana Namacala Omthwalo Wangempela Womhlaba
Isevisi yethu yokuphonsa insimbi igxile ezigabeni ezine zokusebenza—hhayi amamaki engxubevange noma izinhlobo zenqubo. Amavalvu okucindezela adinga izindawo ezivalekayo eziqinile kanye nama-microstructures amelana nokukhathala. Izisekelo zephampu kufanele zimunce ukudlidliza ngaphandle kokukhulisa umsindo ku-1,750 rpm. Izindlu ze-cylinder zidinga ukugxila kwe-bore <0.03 mm ubude obungu-450 mm ngemva kokwelashwa kokushisa. Amarola e-Winch center shaft adinga ukuqina kwendawo ≥240 HBW enobubanzi bekesi obungu-8–12 mm—ngaphandle kokukhishwa kwe-carburization kusixhumi esibonakalayo. Kulokhu, sisebenzisa i-pearlitic grey iron eshintshiwe (i-ASTM A48 Class 40) enezilinganiso ezilawulwayo ze-Mn/Si futhi efakwe ngocingo lwe-FeSi75 + CaAl ukucindezela uhlobo lwe-graphite D. Umphumela? Ukwehliswa okungama-22% esikhathini sokusebenza uma kuqhathaniswa ne-A25 ejwayelekile, kanye nokwehluleka kwenkundla okuyiziro kumayunithi ayi-14,300+ athunyelwe kuma-OEMs asebenza ngomshini waseNyakatho Melika kusukela ngo-2021.
Okulethwa Ukuhlanganisa Okuqondile Empeleni—Ngaphandle Kwezimangalo Zokuthengisa
Abahlinzeki abaningi bakhipha izinsiza, ukwenza imishini, noma ukuqeda. Silawula zontathu—esikhungweni esisodwa esiqinisekisiwe se-ISO 9001:2015. Lokho kusho ukuthi akukho ukunikezwa ngesandla phakathi kwabathengisi lapho ipulaki ye-cobalt-alloy (AMS 5387) idinga ukugaya okunembe *ngemuva* kokusakaza okutshalwa kwezimali, noma lapho ingxenye yephampu esekelwe ku-T800 idinga ukudambisa ingcindezi *ngaphambi* kokuhlolwa kwe-CMM kokugcina. Ngokukhethekile, ukugeleza komsebenzi wethu kushumekiwe: ukuqinisekiswa kwempahla eluhlaza engenayo nge-OES spectrometry; ukuhlola okungaphakathi kwenqubo kusetshenziswa ama-Zeiss CONTURA G2 CMM alinganiselwe ku-ISO 10360-2; kanye nokuhlolwa kokugcina kokusebenza-okuhlanganisa ingcindezi ye-hydrostatic ibambe ku-1.5 × ingcindezi yokusebenza yemizuzu ye-30 kuwo wonke umzimba we-valve. Ukulandeleka akuwona umbiko—kuyisizindalwazi esibukhoma esixhumanisa ingxenye ngayinye eqediwe kumakhemikhali ayo ancibilikayo, ijika eliqinisiwe, kanye nokuqina okungaphezulu kwenani lika-Ra elilinganiswa yi-Taylor Hobson Form Talysurf.
Ukukhetha Uzakwethu Ofanele Wesevisi Yokusakaza Insimbi—Amasheke Amahlanu Angaxoxiswana
- Cela ama-callout wangempela e-GD&T kumasampula okulingisa—hhayi nje “±0.3 mm.” Uma bengakwazi ukukhombisa ukubekezelela indawo ku-Ø12.5H7 bore ehlobene ne-datum A-B-C esithombeni sengxenye yokukhiqiza, hamba.
- Idinga ubufakazi bokuhlanganiswa kokwelashwa kokushisa. Insimbi empunga yezindlu zamaphampu ngokuvamile idinga ukujwayelekile. Ingabe isithando somlilo sabo sinamaphrofayili ahlelekayo we-ramp/soak/cool afakwe iqoqo ngalinye? Noma ingabe “ibekwe kuhhavini ukhohlwe”?
- Qinisekisa ukujula kwesitifiketi esibalulekile. Umbiko wokuhlolwa komshini (MTR) iziteki zetafula. Ukulandeleka okugcwele kusho inombolo yokushisa egxivizwe engxenyeni, exhunywe ekuhlaziyweni kwe-ladle, amabha aqinile ahlolwe nge-ASTM E8 ngayinye, kanye nezithombe ze-microstructure ezifakwe kungobo yomlando.
- Hlola impendulo yabo yokwenza. Bathumele umdwebo onodonga oluncane oluncane (2.8 mm ubukhulu, 120 mm ubude). Uzakwethu wangempela uhlaba umkhosi ubungozi bokushintshashintsha okuyisisekelo futhi uphakamise ukulungiswa kwerediyasi ngaphambi kokusebenzisa ithuluzi—hhayi ngemva kokunqatshelwa kwesihloko sokuqala.
- Qinisekisa isiyalo sokuletha ekugijimeni kwevolumu emaphakathi. Ama-prototypes alula. Bangakwazi ukuthumela imizimba yama-valve engu-420 evikini lesi-6, isonto lesi-7, nesonto lesi-8—ngosuku olufanayo, ukumiswa kwephalethi efanayo, ifomethi yokulebula efanayo? Ukuvumelana kushaya isivinini ngaso sonke isikhathi.
Isevisi yokukhipha insimbi iphumelela lapho i-metallurgy, i-geometry, ne-application physics hlangana khona—hhayi lapho amakhathalogi egcina khona. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha konke ukusakaza njengenodi ethwala umthwalo ohlelweni olukhulu. Ngoba ukwethembeka akuphonswa. Iyakhiwa, iqinisekiswe, futhi ilethwe—inqwaba ngemva kwenqwaba, unyaka nonyaka. Ngensizakalo yokuphonsa insimbi ebaluleke kakhulu, qala ngalokho okumele kwenziwe ingxenye—hhayi lokho okungenziwa inqubo.
