Xa iinjineli zichaza iinxalenye zeempompo zehydraulic, iivalvu ezingaselunxwemeni, okanye iinkqubo zewinch enzima, azifuni nje “intsimbi engoomatshini.” Bafuna uzinzo lwe-dimensional phantsi koxinzelelo lwebar ye-300. Badinga imilomo yengxubevange yecobalt ekwaziyo ukuxhathisa kwi-650°C. Bafuna izindlu eziphosiweyo apho ingqibelelo ye-microstructure ihambelana neefowuni ze-GD & T-ezantsi ukuya kwi-± 0.01 mm. Yiyo loo nto iiOEM zehlabathi jikelele kunye nababoneleli beTier-1 bebuyela rhoqo kwi- umzi-mveliso womatshini wokuchaneka inkulumbuso azimiliselwanga kumabango okuthengisa-kodwa kulawulo lwenkqubo ephindaphindwayo, uqeqesho lwesinyithi, kunye nokuhlolwa kwezero-compromise.
Unyamezelo lwehlabathi lokwenyani luqhuba ukhetho lokwenyani lwemveliso
Sibone iiprojekthi ezininzi zimile kwinqanaba leprototype-hayi ukusuka kuyilo olugwenxa, kodwa kwisakhono esingahambelaniyo. Umxhasi wakhe wasithumelela umzobo wempompo yepiston ye-AMS 5387 enonyamezelo lokwenyani lwendawo ye-Ø0.015 mm kwiibhore ezisibhozo ezibalulekileyo. Umthengisi wabo wangaphambili wayicaphula njenge "CNC-machinable," emva koko wahambisa amaqashiso amathathu alandelelanayo kunye ne-0.032 mm yokutenxa kumphezulu wetywina ongasemva. Ngoba? Ngenxa yokuba be-CNC'd i-sand-cast blank ngaphandle kokunciphisa uxinzelelo kuqala-kwaye abazange balinganise i-thermal drift ngexesha lokugqiba iiyure ezininzi. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha yonke i-micron njengemfuneko esebenzayo, hayi umbhalo osemazantsi ochaziweyo. Indawo yethu ehambelana ne-ISO e-Qingdao idibanisa ukuphosa, unyango lobushushu, kunye ne-5-axis machining phantsi kophahla olunye-kungekhona ukwenzela ukuba kube lula, kodwa ukutshixa kwimemori ephakathi kwimida yenkqubo. Xa umatshini iplagi ye-T800 ye-cobalt alloy emva kotyalo-mali, uxinzelelo olushiyekileyo aluyiyo ithiyori. Yinto etshintsha i-axis yakho yokugqibela nge-0.008 mm. Siyimaphu. Siyayikhulula. Siyayiqinisekisa-phambi kokusika kokuqala.
Ayizizo zonke iivenkile "ze-high-alloy" eziphatha ii-superalloys ngendlela efanayo
Abanye abavelisi babhala "i-cobalt-nickel alloys" kwikhathalogu yabo kwaye bayeke apho. Kodwa amava asixelela ukuba: I-AMS 5387 ayiziphathanga njenge-Inconel 718 xa kusala imilomo ebhityileyo. Isantya sokusebenza nzima sinyuka emva kwe-0.15 mm ubunzulu bokusika. I-thermal conductivity yayo sisiqingatha sensimbi engenasici-ngoko ubomi besixhobo buyancipha ukuba ukuhamba kwe-coolant kwehla ngaphantsi kwe-45 L / min kwi-12,000 rpm. Siqhuba ujongo oluzinikeleyo lwe-spindle kumatshini wethu we-Mazak INTEGREX i-200S-hayi ukuleqa iimethrikhi zexesha, kodwa ukubona iipateni zencoko ezincinci ezandulela ukuthotywa komphezulu. Yiloo ndlela esibamba ngayo i-Ra ≤ 0.4 µm kwiidayamitha zangaphakathi zezihlalo zevalvu ye-cobalt, nakwi-120 mm ubude-to-diameter ratios. Kwaye ewe-siqinisekisa yonke iqashiso ngokuchasene ne-ASTM E112 ubungakanani beengqolowa, ngokwesicelo somthengi. Akukho ngqikelelo. Akukho ndlela zimfutshane.
Ukudityaniswa ngokuthe nkqo kuthetha ukunikezelwa kwezandla ezimbalwa-kunye namanqaku angaphumeleli ambalwa
Cinga ngomzimba we-valve yoxinzelelo: i-iron ductile iron (ASTM A), iphathwa ngobushushu ukuya kwi-28-32 HRC, emva koko ifakwe ngomatshini kunye neendawo zokutywina ezintandathu, izibuko ezine ezinemisonto, kunye ne-press-fit-fit bearing bores-konke ngaphakathi kwe-± 0.012 mm ukukhutshwa okupheleleyo. Ukuba ukuphosa, ukunyanga ubushushu, kunye nomatshini kwenzeka kubathengisi abahlukeneyo, ngubani umnini wempazamo yokupakisha xa indibano yokugqibela ivuza kwibar engama-250? EQINGDAO QIANGSENYUAN, elinye iqela lobunjineli lijongene nolandelelwano olupheleleyo. Isiseko sethu sisebenzisa ukuqinisekiswa kwebhetshi ye-spectrometric ngaphambi kokugalela. Ii-oveni zethu zokuphatha ubushushu zingena kwiiprofayili zexesha lobushushu ngomthwalo ngamnye-hayi ngeshifti nganye. Ilebhu yethu ye-CMM iqhuba ulungelelwaniso oluhambelana ne-ASME B89.1.10M yonke imihla, kwaye inxalenye nganye ifumana uhlolo olupheleleyo lwejometri-kungekhona nje ukujonga indawo. Ukulandeleka akuyongxelo; yikhowudi ye-QR efakwe kwicandelo ngalinye elidibanisa umva kwikhemistri enyibilikayo, i-ID yovavanyo lobunzima, kunye nomsebenzi osayineyo ekuhlolweni kokugqibela.
Le yindlela amacandelo abalulekileyo afumana ukuthenjwa-hayi nje ukuhanjiswa
Abathengi bethu abasikhethi ngexabiso eliphantsi. Bakhetha thina ngenxa yokuba xa i-OEM yepompo yaseYurophu idinga izindlu ze-cylinder ze-47 ezingekho-standard kwi-rig yovavanyo lwe-subsea-kwaye ifuna ii-certs eziphathekayo ezigcweleyo, iingxelo ze-NDT, kunye nedatha yokuvavanya okusebenzayo phakathi kweentsuku ezili-18-babesazi ukutsiba "uyilo lokwenziwa kwezinto" ukuphonononga kuya kubiza ngaphezu kwesicatshulwa. Ke siqhube ukuqinisekiswa kwe-GD&T ngaphambi kokucaphula. Ifunjwe ukunyamezelwa kweprofayile ezimbini ezingahambelani nezixhobo eziqhelekileyo. Kucetywe inkqubo ehlaziyiweyo yogcino-lwazi olubambe umsebenzi ngelixa kucuthwa ixesha lomjikelo ngama-22%. Ihanjiswa ngeshedyuli-kunye nobukhulu obuqinisekisiweyo, yonke indawo egqityiweyo iqinisekisiwe, kunye nejiko ngalinye lokuphatha ubushushu ligciniwe. Leyo sisingqisho sokusebenza sokwenyani umzi-mveliso womatshini wokuchaneka inkulumbuso: Uthethwano lobugcisa olwakhiwe ekuhambeni komsebenzi, aludityaniswanga njengengcinga engemva.
Ukujonga phambili, imfuno ayisiyiyo "yoomatshini obuninzi" -yenzelwe iinkqubo ezikrelekrele ezixubileyo. Ukuphoswa kotyalo-mali kunye nokugrumba i-EDM echanekileyo yeendlela zokupholisa kwiirotor zempompo zoxinzelelo oluphezulu. Ukuphosa kwesanti ngee-thermocouples ezifakwe kwimephu yokuqinisa ngexesha lokwenyani. I-R&D ayikho i-abstract apha-ilinganiswa ngamazinga ancitshisiweyo e-scrap, amaxabiso e-CPk aqina kwiimpawu ezibalulekileyo, kunye nemijikelo ekhawulezayo yokufaneleka kwi-alloys entsha ye-aerospace-grade. Ukuba iprojekthi yakho elandelayo ixhomekeke ekuphindaphindweni-hayi irhetoric-qala ngenkqubo elubala, hayi izithembiso zencwadana. Amalungu akayi kuxoka. Nathi asikwenzi oko.
