Xa inkqubo yakho ye-hydraulic ingaphumeleli phantsi koxinzelelo lwe-350-bar, okanye i-cobalt-alloy pump nozzle iqhekeka emva kweeyure zokusebenza ezingama-472, ingxaki ayifane iqale kwindibano. Iqala ngaphambili-ekukhethweni kwezinto, ukutolika kwe-GD & T, okanye ukusika kokuqala kwi-multi-axis CNC mill. Yiyo loo nto iinjineli zaseMntla Melika naseYurophu zingakhangeli nje "iinkonzo zomatshini zeCNC." Bakhangela a umzi-mveliso womatshini wokuchaneka ophezulu ephatha uzinzo lwe-dimensional njengexesha lekhontrakthi-hayi umnqweno.
Ayizizo zonke iivenkile zokunyamezelana ezisebenza ngendlela efanayo
Siyibonile kabini kulo nyaka: i-Tier-1 yamandla e-OEM yamandla e-OEM ifumene i-AMS 5387 cobalt alloy housings kunye nexabiso le-Cpk ngaphezu kwe-1.67 kwi-diameters yangaphandle-kodwa i-microcracks yomhlaba yavela emva kokuhamba ngebhayisikili yokushisa. Unobangela weengcambu? Umthengisi usebenzise izixhobo eziqhelekileyo ze-carbide ngaphandle kokujonga umthwalo we-thermal ngexesha lokwenyani. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini amacandelo asekelwe kwi-T800 sisebenzisa ukufakwa kwe-PCD epholileyo epholileyo kunye nolawulo lokutya okuguquguqukayo. Yonke imisila ye-spindle torque, isantya sokuqukuqela kokupholisa, kunye nokuguga kwesixhobo-idatha engqanyaniswe kwisiseko sedatha yethu yangaphakathi yokuqinisekisa. Oku asikobunjineli obugqithisileyo. Yindlela obamba ngayo i-± 0.005 mm kwi-210-mm-diameter piston pump cylinder izindlu ngelixa ugcina i-ASTM E112 isakhiwo sengqolowa ingqibelelo.
Indawo yethu ethobela i-ISO e-Qingdao iqhuba ukuphosa okufanayo kunye nokuhamba komsebenzi ngomatshini-hayi ulandelelwano lwezandla. Ukusaswa kwentsimbi kuhamba ngokuthe ngqo ukusuka kwi-mold shakeout ukuya kwii-oveni ezidambisa uxinzelelo, emva koko ziye kumaziko omatshini athe tye anovavanyo oludibeneyo. Akukho ukulungiswa kwakhona. Akukho lungelelaniso luchaza ngokutsha inkqubo. Yiyo indlela esihambisa ngayo iziseko zempompo kunye ne-flatness phantsi kwe-0.012 mm ngaphesheya kwe-1,200 mm-kwaye sizithumele kwiintsuku ze-18 zokukhululwa komzobo.
Udibaniso oluthe nkqo luthetha ukungaqashi malunga nesinyithi
Abanye ababoneleli bangaphandle, emva koko bathenge iibha ezikrwada kwiindawo zokusila. Siphuhlisa izinto eziphathekayo kunye nabavelisi abaqinisekisiweyo be-alloy. Xa umxhasi ecela iiplagi ze-cobalt-nickel zenkonzo yerhasi emuncu, siyaqinisekisa bonke ubushushu obuchasene ne-ASTM A494 iBanga le-CW6MC-hayi nje amandla okuqina, kodwa ukumelana nokudleka kwe-intergranular ngokwe-NACE MR0175/ISO 15156 Annex A. Ukulandelelwa kwebhetshi akuyobhokisi yokutshekisha. Ithegi yensimbi enekhowudi ye-QR edityaniswe kwisiseko ngasinye sokuphosa, edityaniswe neengxelo zohlalutyo lwe-spectral, iilogi zembali ye-thermal, kunye neefayile zokugqibela zokuhlola ze-CMM.
Olu qeqesho lubonisa apho lubaluleke kakhulu: ukusebenza komsebenzi. I-winch center shaft roller eyenziwe kwi-42CrMo4 eqhelekileyo-eyenziwe yaya ku-ISO 2768-mK tolerances, yaqina ukuya kwi-52 HRC, emva koko yaya kutsho kwi-Ra 0.4 µm-yasinda kwimijikelo ye-14,000 kwirigi yovavanyo lwesithuthi sobunjineli ngaphandle kokuthwala isihlalo. Amalungu okhuphiswano awaphumelelanga kumjikelo we-8,920. Umahluko? Umgca wethu wokucoca ubushushu usebenzisa ii-ovens ezilawulwa yi-atmosphere kunye ne-±2 °C efanayo, kungekhona ii-ovens ze-batch ezine-± 15 ° C.
Ukwenziwa kwehlabathi lokwenyani kuqala ngaphambi kokuba itshiphu yokuqala ibhabha
"Ungayenza lonto?" ngumbuzo ongalunganga. Elona lifanelekileyo: "Yintoni eza kuphuka kuqala-kwaye siyimisa njani?" Ngexesha lophononongo lobunjineli, senza iflegi kwi-callouts ye-GD&T engqubana nezithintelo zokubambelela kwi-5-axis mill. Sicebisa ii-angles eziqulunqiweyo kwiimpawu zesanti ezinciphisa ukususwa kwe-post-machining stock ngama-37%. Siphakamisa ezinye izinto-ezifana nokutshintsha kwintsimbi ye-stainless 1.4404 ukuya kwi-duplex 1.4462-xa ukubonakaliswa kwe-chloride kudlula i-120 ppm.
- Siqinisekisa umzobo wejometri ngokuchasene neendlela zokufikelela kwisixhobo-hayi nje imilinganiselo yegama
- Silinganisa ukugqwetheka kobushushu kwizindlu zesilinda ezibhityileyo zisebenzisa iSolidWorks Flow Simulation + empirical shrinkage coefficients.
- Sibuyisela ii-PDF ezichaziweyo kwisithuba seeyure ezingama-48-hayi ii-imeyile "eziqinisekisiweyo" eziqhelekileyo
Akukho mzekelo uya kwintsimbi ngaphandle kwengxelo yeDFM esayiniweyo. Akunjalo kuba sithanda amaphepha. Kuba ukutsiba kubiza i-28,000 yeedola ekusebenzeni kwakhona xa i-valve engekho-standard ifuna ukulungiswa ngokutsha kwezinto ezintathu.
Ukuthembeka akuthenjiswa. Ilinganisiwe, ifakwe kwaye ithunyelwe
Yonke imithwalo ethunyelwayo ibandakanya isatifikethi sokuthotyelwa kwedatha epheleleyo ye-metrology: I-CMM point cloud ye-bore ebaluleke kakhulu, iskeni seprofayili yamehlo yokutywina imiphezulu, ubulukhuni beemephu kwiindawo eziphethwe bubushushu. Asithi "idibana ne-spec." Sibonisa *ngokuchanekileyo* apho kwenzeke khona ukutenxa kwe-0.008 mm-kwaye kutheni ingasebenzi kakuhle (umzekelo, ngaphandle kwe-arc yoxinzelelo).
Yileyo ndlela esigcina ngayo> i-99.2% ngexesha lokuhanjiswa kwexesha le-odolo eliphakathi-nangona i-2024 ye-titanium alloy supply volatility. Umsebenzi wethu obhityileyo ulandelela i-WIP kwinqanaba lesitishi. Ukuba i-cobalt alloy nozzle ibetha ibhotile ekupholiseni, isicwangciso semveliso sivusa indlela ezenzekelayo ukuya kwiiseli zesibini-akukho kunyuka okufunekayo.
A umzi-mveliso womatshini wokuchaneka ophezulu ufumana ukuthembela hayi ngeencwadana, kodwa ngezinto ezisindayo ekusebenziseni intsimi: iivalvu zoxinzelelo zisatywinwa kwiminyaka engama-22 ubudala, iinxalenye zempompo ze-AMS 5387 ezisebenza kumaqonga angaphesheya kwelwandle anexesha lokuphumla elingacwangciswanga elingu-zero, amacandelo e-T800 abambe unyamezelo emva kwemijikelo ye-15 ye-thermal. Ukungaguquguquki kuvela ekuphatheni yonke indawo njengokuba ingena kwinkqubo ebaluleke kakhulu ebomini-kuba rhoqo, kunjalo.
Ukuba iprojekthi yakho elandelayo ifuna ukuphindaphindwa kwe-sub-10-micron kwi-alloys enzima-kumatshini-okanye ukuba sele ulahlile iibhetshi ezimbini zeprototype ukuleqa ukuthotyelwa kwe-GD&T-qala ngokubonakala kwenkqubo, hayi ukucaphula ixabiso. Iqabane elifanelekileyo aligcini nje ukusika isinyithi. Basusa iindlela zokungaphumeleli phambi kokuba umyalelo ubekwe.
