Xa iinjineli zichaza amaqabane efektri yokuphosa i-ductile yentsimbi kwi-mission-critical valves hydraulic okanye izindlu zempompo zoxinzelelo oluphezulu, abafuni nje umthengisi-bafuna ukongezwa kobugcisa beqela labo loyilo. Sibone iiprojekthi ezininzi zilibazisekile ngokukhukuliseka kwe-dimensional drift kwi-santi-cast ductile iron parts, okanye ichithwe ngenxa yokungahambelani kwe-nodularity kwiibhetshi ze-ASTM A536 zeBanga 65-45-12. Yingakho ukuchaneka akusiyo ibango lokuthengisa-yinto esisiseko esingaxoxisiyo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza apho i-metallurgy idibana nomatshini: indawo eqinisekisiweyo ye-ISO eQingdao ephatha yonke i-ductile iron casting njengenxalenye esebenzayo kuqala, hayi nje imilo yesinyithi.
I-Ductile Iron Casting Factory: Apho iNzululwazi yeMathiriyeli iDibana neMijikelo yoMlayisho yokwenyani weHlabathi
Uninzi lwee-iron ductile foundries zilungiselela umthamo okanye ixabiso ngetoni nganye. I-QINGDAO QIANGSENYUAN ilungiselela *ukuthembeka okusebenzayo phantsi koxinzelelo lomjikelo*. Inkqubo yabo yokugalela isanti iqala ngezinto ezifunyaniswayo eziqinisekisiweyo-akukho ngxubevange yezinto ezilahlwayo-kwaye ilandelela ubushushu obusuka kwiladle ukuya kuhlolo lokugqibela. Baqinisekisa i-nodular graphite morphology usebenzisa uhlalutyo lomfanekiso nge-ASTM E2371, kungekhona nje imivalo yokuqina. Yiloo ndlela abaqinisekisa ngayo ubude obuguquguqukayo (≥12%) kunye namandla esivuno (≥450 MPa) kwi-500-piece lots of piston pump cylinder housings-amacandelo abona 3,000+ psi uxinzelelo spikes rhoqo 90 imizuzwana kwi offshore oil & gas skids.
Oku akuyothiyori. Kwiprojekthi ye-OEM yaseMntla yaseMelika ye-hydraulic, ababoneleli abakhuphisanayo bahambisa izindlu kunye ne-0.18 mm bore taper emva komatshini-ukugqithisa i-GD & T callouts yokugxila. I-QINGDAO QIANGSENYUAN's castings ibambe ≤0.05 mm pre-machining taper, ngenxa yokuba iimodeli zabo zesoftware yokulinganisa i-thermal shrinkage vectors ezithe ngqo kuluhlu lwe-ductile iron eutectic solidification-hayi iparameters zentsimbi engwevu.
Udibaniso oluthe nkqo Oluphelisa ukusilela kweHandoff
Iivenkile ezininzi "zendawo enye" zenza izixhobo zokukhupha, ukwenza oomatshini, okanye unyango lobushushu. I-QINGDAO QIANGSENYUAN ingabanini bobathathu. Iiseli zabo ze-CNC zisebenza ngokuthe ngqo kumphezulu we-as-cast-akukho ukulungiswa kwakhona, akukho kutshintsha kwedatum. Kwi-winch center shaft rollers ezisetyenziswa kwimingxuma yokugrumba imigodi, oko kuthetha ukuba umzila womdyarho wangaphandle oqinileyo (HRC 58–62) ugcina ±0.015 mm ubungqukuva xa uthelekiswa nebhore engaqiniswanga, kuba kwa lo mqhubi uqinisekisa ubume bemicrostructure yokuphosa kwakhona ucwangcisa i-5-axis mill egqiba iijenali ezithweleyo.
- I-AMS 5387 i-cobalt alloy yempompo yeendawo zempompo ezenziwe ngoomatshini endlwini-akukho zikontraka zangaphandle zokusila ezizisa ukuphuma
- Imilomo esekwe kwi-T800 igqitywe ngokudubula okulawulweyo ukukroba ukuphembelela +200 MPa umphezulu woxinzelelo loxinzelelo.
- Imizimba yevalve yoxinzelelo ehlolwe ngeeCMM ezilinganiswe kwi-ISO 10360-2, enengxelo epheleleyo ye-GD&T nge-ASME Y14.5–2018
Olo lawulo oluthe nkqo luthintela imowudi yokungaphumeleli yakudala: ukuphosa okugqibeleleyo konakaliswe sisixhobo somatshini esingalungelelanisiweyo, okanye inxalenye yomatshini engenasiphako eyaliwe emva kokuba unyango lobushushu lurhwebeshele kwidatum ebalulekileyo.
Umgangatho Obhaliweyo-Awuchazwanga
Ukulandeleka akuyobhokisi yokukhangela. Yonke i-ductile iron casting iphethe ikhowudi ye-QR edibanisa nengxelo yayo yovavanyo lwezinto eziphathekayo, ilogi enyibilikayo, idatha yokuhlola i-dimensional, kunye novavanyo lokugqibela olubonakalayo. Xa umenzi wempompo waseYurophu efuna ukuthotyelwa kwe-ISO 15156 yenkonzo emuncu, i-QINGDAO QIANGSENYUAN ibonelele ngeerekhodi zovavanyo ezipheleleyo ze-HIC (i-hydrogen-induced cracking)-hayi nje isatifikethi. Iiprothokholi zabo zokuhlola zifuna ukutshekishwa okuthathu okuzimeleyo ngaphambi kokukhululwa: ukuqinisekiswa kwezinto ezingenayo, inkqubo ye-CMM scan kwinqanaba lomatshini olukhuni, kunye novavanyo lokugqibela olusebenzayo kwiirigi ze-hydraulic ezakhiwe ngokwesiqhelo ezilinganisa ukuhamba kwebhayisikile yoxinzelelo lwehlabathi lokwenyani.
Siyiphicothe inkqubo yabo kabini. Eyona nto ibalaseleyo ayikokuthobela nje—kukulindela *ulindelo. Iqela labo lobunjineli lifakela imigibe enokubakho kwi-porosity kumacandelo amancinci ngexesha lokuphononongwa komzobo, icebisa ukuguqulwa kwe-gating ukuphepha ukucutha imingxuma kufutshane neendawo zokuhlala zevalvu, kwaye iqinisekisa imijikelezo yokuphatha ubushushu usebenzisa iJominy ukuqina kwamagophe-kungekhona nje ixesha / iitshati zobushushu.
Kutheni iiNjineli zeHlabathi zikhetha le Factory yokuCasa i-Iron Ductile
Iza phantsi ekunciphiseni umngcipheko. Xa izixhobo zomthengi wakho ziqhuba i-24/7 kwiindawo ezikude, ixesha lokuphumla libiza i-$ 18,000 / iyure. Awunakukwazi ukuhlawula iziphene zokuphosa ezibonakala kuphela emva kweeyure zokusebenza ezingama-200-okanye ukungafani komlinganiselo onyanzelisa ukusetyenzwa kwakhona kwentsimi. Ugqaliselo lwe-QINGDAO QIANGSENYUAN kumacandelo achanekileyo akwi-alloy ephezulu kuthetha ukuba bayayigatya i-37% yee-RFQ zokuqala ezingenayo i-GD & T enokwenziwa okanye i-stacks yokunyamezela yokwenene. Bangathanda ukuthi "hayi" kunokuhambisa inxalenye ephumelele ukuhlolwa kodwa isilele kwinkonzo.
Amandla abo akalingani-yinto ekhethekileyo. Abaphosi iibhloko zenjini okanye izigqubuthelo zemingxuma kamasipala. Baphosa iivalvu zoxinzelelo ezivale i-7,500 psi, izindlu zesilinda ezisinda kwimijikelo yoxinzelelo lwezigidi ezili-10, kunye neeshafti zewintshi ezisasaza i-torque engama-42 kN·m ngaphandle kokusasazwa kwe-microcrack. Olo gxininiso lumxinwa lwakha inkumbulo yezihlunu akukho siseko se-generalist sinokuphindaphinda.
Ukuba ukhangela amaqabane efektri yokuphosa intsimbi kwiindawo apho ukungaphumeleli kungayiyo inketho, qala ngokulandeleka kwezinto, qinisekisa amandla abo e-metrology yangaphakathi, kwaye ufune ubungqina bovavanyo olusebenzayo-hayi nje iingxelo ezinobungakanani. Ukuchaneka akwenziwa kwinqanaba elinye. Yenzelwe kubo bonke ubushushu, ukungunda konke, yonke inguquko yokusonta.
