Xa iinjineli zicacisa ukuphoswa kwensimbi engenasici kwiivalvu zehydraulic ezinoxinzelelo oluphezulu okanye izindlu zempompo ezinxibayo, azikhethi nje izinto eziphathekayo-zibheja ngokuzinza kwe-dimensional, microstructure integrity, kunye ne-batch-to-batch consistency. Kungenxa yoko le nto kufunwa umntu ozinikeleyo steel stainless casting factory izinto ezibaluleke ngakumbi kunanini na ngaphambili-hayi isiseko esiqhelekileyo, kodwa esakhelwe malunga nokuchaneka, ulawulo lwe-metallurgical, kunye nokuqinisekiswa kokusebenza.
Kutheni “iFactory yokuphosa intsimbi engenaStainless” iluphawu lobuGcisa—hayi nje igama eliphambili
Ukukhangela "ifektri yokuphosa insimbi engenasici" kaninzi kuvela kubaphathi beentengo kunye neenjineli zokuyila ezijongene nokungaphumeleli kwehlabathi lokwenyani: impompo yepiston yezindlu eqhekekileyo kwi-bar ye-350, i-cobalt-alloy nozzle ilahlekelwa ukunyamezela emva kokuhamba ngebhayisikile yobushushu, okanye i-winch centre shaft roller ebonisa ukukhathala kwangaphambi kwexesha. Ezi ayizizo iinkxalabo zethiyori. Siye sabona izizathu ezintathu eziphindaphindiweyo kwimbuyekezo yentsimi: ukwakheka okuziinkozo okungahambelaniyo ukusuka kumazinga okupholisa angalinganiyo, i-warpage ye-residual-induced warpage emva kokugqiba i-CNC, kunye ne-trace element drift kwi-17-4PH okanye i-F22 castings ephazamisa i-HRC 38-42 ekujoliswe kuyo emva kokutshisa ukushisa.
Umzi-mveliso wokwenyani wentsimbi engenastainless ujongana nolu mlambo-kungekhona ngokuhlola kuphela, kodwa ngobunini benkqubo edibeneyo. Ilawula ikhonkco lilonke: ukulandeleka kwebillet ekrwada eqinisekisiweyo, isanti okanye ukulinganisa undondo lotyalo-mali phambi kokugalelwa, umfuziselo wokuqinisa amacandelo abalulekileyo afana nomqala wesivalo sevalve, kunye nolungelelwaniso lwezixhobo zomatshini ezireferensi njenge-datums. Oku ayisongezo-yisiseko.
Izakhono ezine ezingaxoxisiyo ongenakukwazi ukuzikhupha ngaphandle
Nawuphi na umthengisi unokucaphula iicasts zensimbi ezingenasici. Bambalwa abahambisa iinxalenye ezibalulekileyo zobuthunywa ngokuthembekileyo. Nantsi into eyahlula abadlali abaqinisekisiweyo:
- Umnombo wezinto eziphathekayo kunye nokungacaci kakuhle: Isitokhwe esiluhlaza asikho nje "i-316L" -ithwala iingxelo zokuvavanya i-mill ebonisa iindidi zangempela ze-Cr / Ni / Mo (umzekelo, i-16.8-17.2% Cr, kungekhona i-16-18%), isulfure ≤0.005%, kunye nomxholo we-oksijini oqinisekisiwe ngokuhlalutya kwe-LECO. Kwiinxalenye ze-AMS 5387 cobalt alloy, oku kuthetha ukuqinisekiswa kwe-Co ≥60.5%, Cr 28-30%, kunye ne-Si ≤0.25%-hayi nje "ihambelana ne-spec".
- Ukuphosa-omatshini ujongano lojongano: Akukho zilophu zokuphinda zisebenze. Xa indlu ye-cylinder ifuna i-± 0.015 mm ukujikeleza kwe-ID emva kokubhoboza kokugqibela, ubukhulu bodonga lwe-as-cast kufuneka bubanjwe ukuya ku-± 0.3 mm-hayi ± 0.8 mm-ukuphepha ukugqithisa kunye nomonakalo we-microstructural. Oko kufuna uyilo lwe-toolpath-aware gating kunye nexesha lokwenyani lokujongwa kwe-thermal ngexesha lokugalela.
- Ukuqinisekiswa okusebenzayo-hayi nje ukujonga umyinge: Umzimba wevalve yoxinzelelo udlula ukuhlolwa kweCMM kodwa uyasilela uvavanyo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza? Oko kukhomba kwi-porosity engaphantsi komhlaba ephoswe ziindlela ezibonakalayo okanye zedayi-pen. Ubunakho bokwenyani bubandakanya iX-reyi (ASTM E94) kwi-100% yamacandelo abalulekileyo kunye novavanyo lokuvuza nge-ISO 15848-1 yemizimba yevalvu.
- Isicwangciso semveliso esiqhutywa yi-GD&T: Xa umzobo wakho ubiza unyamezelo lwendawo ye-Ø0.05 mm ngokunxulumene nedatum esekwe kwi-flange ebhityileyo, umzi-mveliso kufuneka ulinganise ukuphambuka okubangelwa ukulungiswa *phambi* kokusika inxalenye yokuqala-kwaye ubonise ngeengxelo zokuseta kwangaphambili usebenzisa oomatshini bokulinganisa abalungelelanisiweyo abalinganiswe kwi-ISO 10360-2.
Yintoni efunwa zizicelo zeHlabathi zokwenyani-kwaye zibumba njani iiNkqubo zokuKhetha
Iinkqubo ze-hydraulic eziphezulu zokusebenza azisileli ngokungalindelekanga. Bayasilela apho ifiziksi igxininise uxinzelelo: kwiradio ebukhali yangaphakathi kwiziseko zempompo, kwindawo ekudityanwa kuyo amacandelo ashinyeneyo nabhityileyo kwizirolo zewinch yemoto yobunjineli, okanye ecaleni koguqulo lwendlela yokuhamba kwimilomo ye-cobalt-alloy. Imowudi yokusilela nganye yenza imephu ngokuthe ngqo kwimfuno yenkqubo:
I-T800 ye-cobalt esekwe kwiziko leshaft roller idinga isithuba sengalo ye-dendrite efanayo kwidayamitha yayo eyi-220 mm-iphunyezwe kuphela ngokuqiniswa komkhombandlela kwizingundo zesanti ezixhaswe ziipleyiti zentsimbi ezibandayo. I-F22 yentsimbi engenastainless yoxinzelelo lwevalvu yendlu ifuna isisombululo se-annealing kwi-1040°C ±5°C kunye nokupholisa okulawulwayo ukunqanda ukwakheka kwesigaba se-sigma kwindawo echatshazelwe bubushushu kufutshane nemigangatho yokutywinwa ngoomatshini. Kwaye i-AMS 5387 pump cylinder kufuneka iguge kabini (870 ° C/4h + 760 ° C/16h) ukuze ibethe amandla okuqina ≥1380 MPa ngaphandle kokugquma indawo ebhorekileyo.
Ezi ayizo "ukhetho." Zingamanyathelo angenakuxoxisana afakwe kwimiyalelo yomsebenzi-engafakwanga njengezohlukileyo.
Ukukhetha iqabane lakho: Jonga iZatifikethi ezidlulileyo, Gxila kubungqina
I-ISO 9001 ziziteki zetafile. Okubalulekileyo kukuba ubukhali buguqulelwa njani kwinani lenxalenye yakho. Cela:
- I-Batch-specific material certs enohlalutyo olupheleleyo lwe-spectrographic-hayi nje amagama ebakala
- Iilogi zomjikelo wobushushu bomjikelo obonisa iiprofayili zokwenyani zobushushu beziko, hayi nje iindawo zokubeka
- Iingxelo ze-CMM ezine-callouts ze-GD&T ezigqunywe kwiimodeli ze-CAD, hayi nje ukudlula/ukungaphumeleli kwezitampu
- Idatha yoburhabaxa bomphezulu (Ra, Rz) ilinganiswe kwiizowuni ezisebenzayo-hayi nje "njengoomatshini" amanqaku
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha udumo lwayo ekunikezeni kanye obu bungqina-kungekhona njengamaxwebhu, kodwa njengesiqhelo sobunjineli. Indawo yayo ye-Qingdao iphatha yonke i-odolo-ukusuka kwi-prototype yezindlu ze-valve ukuya kwi-middle-volume run of piston pump cylinders-njengenkqubo evaliweyo ye-loop: ukuhlaziywa koyilo kuqinisekisa ukuveliswa ngokuchasene nokuchithwa kunye nokufikelela kumatshini; ukuqinisekiswa kwezinto ezingenayo zijonga iziqinisekiso zababoneleli nge-OES yangaphakathi; kunye nokukhululwa kokugqibela kufuna utyikityo kuzo zombini imilinganiselo yothotyelo *kunye* nokusebenza okusebenzayo ngokuchasene nemvulophu yakho yokusebenza.
Yiloo ndlela umzi-mveliso wokuphosa wensimbi engenasici ufumana ukuthenjwa-kungekhona ngezithembiso, kodwa ngokulandeleka, okuphindaphindwayo, ukubulawa ngentlonipho yefiziksi. Ngexesha elizayo xa ukhankanya icandelo elingenasidima esiphezulu, ungabuzi nje ukuba "Ngaba ungayiphosa?" kodwa "Uqinisekisa njani ukuba ayizukusilela apho kubaluleke kakhulu?" Impendulo kufuneka iqale ngenkqubo, hayi ngamaphepha.
