Xa iinjineli zichaza a umzi-mveliso wesinyithi kwi-mission-critical valves hydraulic valves okanye i-high-wear pump housings, ayithengi nje iinxalenye-zikhusela uzinzo lwe-dimensional phantsi kwe-350-bar yoxinzelelo, ukunyaniseka kwe-microstructure emva kokunyanga ubushushu, kunye nokulandelwa kwebhetshi epheleleyo ukuya kwinani elinyibilikayo. Yiyo loo nto amaqela oyilo eMilwaukee, eStuttgart, naseSingapore eqhubeka ebuyela kwindawo enye eQingdao: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Kutheni le nto “izahlulo zentsimbi yesiNtu” Ayingomgca weThegi-Yinkqubo yoLuleko
Siye sabona iiprojekthi ezininzi kakhulu zivaliwe kwinqanaba le-prototype-kungekhona ngenxa yoyilo oluphosakeleyo, kodwa ngenxa yokuba ivenkile ayikwazanga ukubamba ± 0.015 mm kwi-AMS 5387 cobalt alloy nozzle umqala ngelixa igcina i-surface finish Ra ≤ 0.4 μm. I-QINGDAO QIANGSENYUAN ayiliphathi isiko njengento eyahlukileyo. Yakhelwe kulo lonke inyathelo lokuhamba komsebenzi: Ukuqinisekiswa kwe-GD&T ngaphambi kokucaphula, isatifikethi sezinto eziphathekayo sikhangelwe ngokuchasene neengxelo zovavanyo lokugaya, kunye nokuhlolwa kweCMM ecwangciswe ngokuthe ngqo kwiifayile ze-STEP zabathengi-hayi iiPDF.
Iziko labo elithobela i-ISO liqhuba imigca yokuphosa enxuseneyo kunye neyomatshini. Ukuphosa kwesanti kubamba iziseko zempompo ezinkulu ukuya kuthi ga kwi-1,200 kg; utyalo-mali luhambisa amacandelo e-cobalt-nickel abhityileyo anobunzima bodonga obusezantsi njenge-2.3 mm. Iiseli ze-CNC ke zisebenza ngomatshini wokubhoresa okubalulekileyo, umphezulu wokutywina, kunye neeflange ezixhomayo-zonke zikwiseto enye apho kunokwenzeka. Akukho handoffs. Akukho ukulungiswa kwakhona. Akukho datha zilahlekileyo.
Oku akuyothiyori. Isixhobo sendawo yeoli yaseMntla Melika iOEM yayidinga izindlu zesilinda zepiston ezisinde iiyure ezili-12,000 kubomi benkonzo yeeyure kwiindawo zerhasi emuncu. Abakhuphisana bacaphula insimbi engenasici 316L. I-QINGDAO QIANGSENYUAN ecetywayo ye-ASTM A494 CW6MC (i-cobalt-based superalloy), iqhube uvavanyo lomhlwa ngokwe-NACE MR0175/ISO 15156, yaza yanikezela ngeenxalenye zenqaku lokuqala ngobulukhuni be-38–42 HRC kuwo wonke umphezulu webhore—iqinisekiswe yi-Rockwell C iskena rhoqo nge-50 mm.
Iindidi ezine zeMveliso-INjineli enye yobuNjineli
Abaleqi umthamo. Bagxila kwiindidi ezine ezichazwe ngokuqinileyo apho i-metallurgy, ijometri, kunye nomsebenzi udibana:
- CNC oomatshini iindawo:Iivalvu zoxinzelelo ezineredidi ezidityanisiweyo zokuqukuqela, iirola zeshaft zewinch ezineendlela eziqinileyo zomdyarho, kunye neeadaptha zeflange ezingasiyo mgangatho ezifuna ukugxila <0.02 mm
- Amacandelo e-cobalt-nickel alloyImilomo ye-AMS 5387, iiplagi ze-alloy ze-T800, kunye neejometri zesiko apho ukuxhathisa i-galling kubaluleke ngaphezu kweendleko-nge-kg
- Ukuphoswa kwentsimbi: Iziseko zempompo ezenzelwe ukudambisa ivibration, kunye ne-graphite morphology elawulwayo eqinisekiswe ngeASTM E2371 metallography
- Intsimbi kunye neesanti zentsimbi: Izindlu ze-cylinder ezine-17-4PH (H900) eziqinisekisiweyo ezimbini (i-H900) + i-post-machining yokunciphisa uxinzelelo lokuthintela ukuphazamiseka
Qaphela into engekhoyo: i-hardware yokuhombisa, i-sheet metal evaliweyo, okanye izibophelelo eziqhelekileyo. Olu gxininiso luthetha ukuba ithala leencwadi labo libandakanya ukufakwa kwe-carbide yesiko kwi-cobalt alloys, iindlela zembuyekezo yokwandisa ubushushu bokwenziwa okukhulu ngexesha lokwenziwa komatshini, kunye neeprothokholi zokugqiba umphezulu eziqinisekisiweyo ngokwe-ISO 1302-hayi nje "njengoko kufuneka."
Ulawulo Lomgangatho Onokuwuphicotha—Akupheleli nje Ukukholosa
Ezinye iivenkile zikubonisa isatifikethi sokuthotyelwa. QINGDAO QIANGSENYUAN ikunika idatha ekrwada. Yonke into ethunyelwayo ibandakanya idosi yedijithali: iicerti zezinto ezingenayo, iitshati zonyango lobushushu kunye nexesha lokufunxa / lobushushu, iingxelo zeCMM ezibonisa eyona nto ithelekiswa negama layo yonke i-callouts ye-GD&T, kunye neerekhodi zokuhlola ezibonwayo ezineefoto ezichaziweyo zeendawo ezibalulekileyo.
Sibuze umxhasi we-hydraulics waseYurophu ukuba baqinisekisa njani na ukuhambelana kuzo zonke iibhetshi. Impendulo yabo: "Sitsala iisampulu ezingaqhelekanga kwaye siqhuba iimvavanyo zetyuwa-spray nge-ASTM B117. Kunyaka ophelileyo, i-100% yadlula iiyure ze-96 ngaphandle kwe-rust ebomvu-isiphumo esifanayo kwimiba emithathu yokuvelisa, inani elifanayo lempahla elandelwayo kwilog yesithando somthengisi." Elo nqanaba lolawulo liqala ngemathiriyeli ekrwada eqinisekisiweyo-kwaye ayipheli de kube yinxalenye yeenqanawa.
Kwaye ewe, bajongana nezicelo ezingekho mgangathweni. Umzi-mveliso wokukhupha ityuwa kuMzantsi-mpuma weAsia wawufuna iplagi etshintshiweyo yevalve yenaliti ene-high-pressure brine-akukho mizobo ekhoyo, yisampuli egugileyo kuphela kunye nespekthi zokusebenza. Iqela labo lenze umva-injineli yejometri, yakhetha i-T800 alloy yokumelana nokhukuliseko, yaqhuba i-FEA kugxininiso loxinzelelo kwiradius yamagxa, kwaye yazisa iiprototypes ezisebenzayo ngeentsuku ezili-11.
Ukuthembeka Kuqala Phambi KokuSika Kokuqala
A umzi-mveliso wesinyithi ufumana ukuthembela kwakudala phambi kokuba kuqale ukusebenza. Kulapho uphononongo lobunjineli be-QINGDAO QIANGSENYUAN lukhaba-kungekhona njengomgcini-sango, kodwa njengomdibanisi. Bafaka iflegi imingcipheko yokwenziwa kwangaphambili: ikona yangaphakathi eyi-0.5-mm-radius enokufuna i-EDM endaweni yokugaya, umlinganiselo oyimfama ubunzulu ukuya ku-diameter ratio edlula i-6: 1 kwi-cobalt alloy, okanye i-surface finish spec engahambelani nesakhiwo senkozo yesanti.
Ulawulo lweprojekthi yabo alulindi ii-PO. Ukuqinisekiswa komzobo kwenzeka kwiiyure ezingama-48. Utoliko lwe-GD&T lubandakanya ukuhlalutya kokunyamezela. Nezibophelelo zonikezelo? Zisekwe kwixesha lokwenyani lomatshini-hayi izibalo zekhalenda ezinethemba. Iiodolo ezinomthamo ophakathi zithunyelwa kwiiveki ezi-6-8. Iiprototypes zihlala kwiintsuku eziyi-10-14. Akukho nto imangalisayo. Akukho "intlawulo ekhawulezayo" yokuhlangabezana neshedyuli yakho.
Ukujonga phambili, umbhobho wabo we-R&D ujolise kwiinkqubo ezixubileyo-ezifana ne-net-shape investment castings egqitywe nge-multi-axis milling ukuphelisa imisebenzi yesibini-kunye nezatifiketi ezandisiweyo zamacandelo ebakala lenyukliya (ASME BPVC Section III) kunye ne-aerospace (i-NADCAP yokushisa ukushisa). Kodwa amandla anamhlanje ahlala engaguqukiyo: ukuhambisa iinxalenye zetsimbi eziqhelekileyo ezenza-kungekhona nje ukufaneleka.
