Lapho ivalvu yakho ye-hydraulic valve kufanele ibambe ±0.02 mm ukubekezelela ngaphansi kwe-350 bar pulsation-noma i-cobalt alloy pump nozzle yakho iphila amahora angu-8,000 kusevisi yegesi emuncu-awugcini nje ngoku-oda ukukhishwa. Uyafaneleka a ukunemba casting Foundry ifektri njengesandiso sobuchwepheshe sethimba lakho lobunjiniyela.
Sibone amaphrojekthi amaningi kakhulu egxilile esangweni le-foundry: ukukhukhuleka kwe-dimensional ngemva kokwelashwa kokushisa, ukushwabana okuncane ezigabeni ze-AMS 5387 ezinodonga oluncane, ama-callouts e-GD&T ahunyushwe ngokungeyikho ngokuthi “ububanzi obamukelekayo” esikhundleni semikhawulo eqinile. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., konke ukulingisa siphatha njengengxenye esebenzayo—hhayi into engenalutho ezokwenziwa kamuva. Lokho kusho ukulawula i-metallurgy *ngaphambi* kokuthela, ukuqinisekisa ukwakheka kokusanhlamvu *ngemuva* kokuqina, nokukhiya ijometri *ngesikhathi* sokuqedela i-CNC—konke ngaphansi kophahla olulodwa olunesitifiketi se-ISO e-Qingdao.
Kungani ukubekezelelana kokukhipha kuqala isikhathi eside ngaphambi kokuba isikhunta sivale
Ukwehluleka okuningi kokulingisa okunembayo kulandelela emuva ezikhaleni ezintathu ezingagwemeka: ukungahambisani kwezinto, ukuhlukaniswa kwenqubo, namaphutha we-dimensional handoff. Siwavala ngamabomu.
Okokuqala, ukulawulwa kwezinto ezingavuthiwe akuphathelene nezitifiketi-kumayelana nokulandeleka kwezinga le-batch phansi kulogi encibilikayo. Uma ucacisa ingxubevange esekelwe ku-cobalt ye-T800, sithola kubahlinzeki abaqeqeshwe kusengaphambili abahlinzeka ngemibiko egcwele ye-spectrographic *kanye* nedatha yomlando oshisayo we-ingot ngayinye. Ayikho i-chemistry "ejwayelekile". Akukho okucatshangelwayo "njengoba-cast". Konke okuthululwayo kuqinisekiswa ngokumelene namajika ezakhiwo ze-AMS 5387—hhayi nje amandla aqinile, kodwa ukunwetshwa kokuqhekeka nokuqina kokuqina kuwo wonke ugqinsi lwezigaba.
Okwesibili, ukuhlanganiswa okuqondile kususa ukubekezelela isitaki esibulala izingxenye ezinemba okuphezulu. Ukufakwa kwesihlabathi kukodwa akukwazi ukubamba ±0.15 mm kusilinda sezindlu esingu-400 mm. Kodwa uma ithimba lethu labasunguli lidizayina ngokuhlanganyela amasistimu okufaka isango nonjiniyela bemishini—futhi womabili amaqembu abuyekeza umbiko ofanayo we-CMM ngephethini yesihlabathi esiluhlaza—sisusa amaluphu okusebenza kabusha. Umugqa wethu wokutshala imali uphatha amaphaseji angaphakathi ayinkimbinkimbi kuma-valve okucindezela; umugqa wethu wesihlabathi ukhiqiza izisekelo zephampu ezinkulu ezifika ku-1,200 kg-zombili zidla ngokuqondile kumaseli e-CNC e-axis emihlanu lapho amabhorefa okugcina, izindawo zokuvala, kanye nobuso obukhuphukayo kufakwa ngomshini ngokusetha okukodwa.
Okwesithathu, ukuhlola akuyona indawo yokuhlola—ukuqinisekisa okuqhubekayo. Izinto ezingenayo zithola i-spark spectrometry nokuhlolwa kwe-ultrasonic. Ukuhlola okungaphakathi kwenqubo kusebenzisa ama-Zeiss CMM anama-probe alinganiselwe kuma-datum abalulekile, kanye neziqhathanisi ezibonakalayo zezici ezizwelayo ephrofayilini njengama-nozzle orifices. Ukuhlola kokugcina kufaka phakathi ukuhlolwa kwengcindezi esebenzayo (kufika kumabha angama-500), ukungena kukadayi ukuze uthole amaphutha angaphansi komhlaba, nokuqinisekiswa kokuqina kwendawo ngayinye ye-ISO 4287—okubhalwe kudosi egcwele yokulandeleka eboshelwe engxenyeni yezinombolo ze-serial.
Lapho ama-Foundries ajwayelekile ema, ukusakaza okunembayo kuqala
Abanye bangase baphikise: "Umshini we-CNC unikeza ukubekezelelana okuqinile kunokulingisa - pho kungani uphonswa?" Kuvumelekile—kodwa akuphelele. Ukukhanda indlu yephampu yepiston engu-300 mm kusuka kumfucuza wensimbi engenasici kumosha u-78% wempahla eluhlaza, kudala ingcindezi eyinsalela, futhi kubeke engcupheni ukuhlanekezela ngesikhathi sokwelashwa kokushisa. Ukusakaza umumo oseduze nenethi bese uqeda izindawo ezibucayi kuphela kunciphisa isikhathi sokuhola ngo-40%, kunciphisa ukuhluka kwesisindo phakathi kwamaqoqo, futhi kulondoloza ukugeleza okuqondile okusanhlamvu kokumelana nokukhathala.
Umahluko wangempela? Ukuphatha lokho abanye abakwenqabayo. Ingxubevange ye-cobalt-nickel efana ne-AMS 5387 ayinzima nje ukuwenza umshini—ayizinzile ngokushisa. Ukushisa ngokweqile ngesikhathi sokugaya? I-oxidation ye-grain boundary oxidation ibhubhisa ukumelana nokugqwala. I-undercool ishesha kakhulu ekulingiseni? I-Micro-porosity yakha ezinguqukweni eziwugqinsi ukuya kwezincane. Sisebenzisa isofthiwe yokulingisa okushisayo kuyo yonke ingxenye yejiyomethri entsha, silungisa amazinga okupholisa ngesikhathi sangempela sisebenzisa ama-thermocouples ashumekiwe, futhi siqinisekisa i-microstructure nge-metallographic cross-sections—hhayi kuma-athikili okuqala kuphela, kodwa ngekota ezindaweni zokukhiqiza.
Izingxenye zethu eziceliwe kakhulu ziyakufakazela lokhu: izindlu zesilinda sephampu ye-piston ezinokugxila <0.03 mm ububanzi obungu-600 mm; ama-winch center shaft roller anezindawo zokugqoka eziqinile ahlangana ne-ASTM A957 yeBanga le-100 ye-tensile specs; amapulaki e-cobalt angajwayelekile anemifantu enezinsimbi ezimbili edinga ububanzi begroove engu-±0.015 mm kanye nokuqedwa kuka-Ra 0.4 μm. Lezi akuzona izinto zekhathalogi. Ziyizixazululo ezinobunjiniyela—lapho amapharamitha okusakaza, imijikelezo yokwelashwa kokushisa, namasu omshini enziwa ngokuhlanganyela kusukela kuSuku Lokuqala.
Ungayihlola kanjani imboni ye-foundry yeqiniso yeqiniso
Buza le mibuzo emithathu—futhi ubuke ukuthi iphendula kanjani:
- “Ngibonise imibiko yakho yokugcina emithathu ye-CMM engxenyeni enama-callout e-GD&T aqine kuno-±0.05 mm.” Uma bengabaza, noma babelana ngezifanekiso ezijwayelekile, hamba. Izitolo zangempela zigcina izingobo zomlando ezigcwele zedijithali.
- "Ukulawula kanjani ukuncipha odongeni oluyi-12 mm eduze komphathi ongu-45 mm?" Izimpendulo ezingacacile mayelana nokuqagela kwesignali "yomklamo oyinhloko". Izitolo ezinembile zibhekisela kokuphumayo kwamamodeli wangempela okushisa futhi zibonisa i-delta elinganiselwe phakathi kobukhulu be-as-cast kanye ne-post-HT.
- "Lingakanani izinga lakho lokwenqatshwa ekulingiseni kwe-AMS 5387 ezinyangeni eziyi-12 ezedlule-futhi ibiyini imbangela yokwehluleka kokuthathu okuphezulu?" Ukubonisa ngale lapha kwehlukanisa ozakwethu kubathengisi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ishicilela ideshibhodi yayo yekhwalithi yaminyaka yonke ngaphakathi—futhi yabelana ngamamethrikhi afanelekile nozakwethu abaqeqeshiwe uma icelwa. Izinga lethu lamanje lokuthobela ubukhulu besilinganiso sokuboniswa kokubekezelela okuphezulu limi ku-99.73%, ngokuchezuka okuhlobene nokuncipha okubalela okungaphansi kuka-0.8% okungahambisani—yehle ukusuka ku-2.1% eminyakeni emibili edlule ngemva kokuthuthukisa uhlelo lwethu lokuqapha izinga lokushisa kwesikhunta.
Izingxenye zensimbi ezibekezelela kakhulu aziveli emidwebeni ephelele. Zivela engcupheni okwabelwana ngayo, izinqubo ezibhaliwe, kanye nokunaka okungaphezi kokuthi kwenzekani phakathi kokuthululwa okuncibilikisiwe nokuthinta kokuhlola kwe-CMM kokugcina. A ukunemba casting Foundry ifektri ayichazwa ngemishini yayo-ichazwa ngokuthi ihlanganisa ngokuqinile kanjani isiyalo se-metallurgical ngokuqiniseka kwejometri. Lokho izinga esakhela kulo. Njalo thela. Yonke ingxenye. Zikhathi zonke.
