Xa i-valve yakho ye-hydraulic ingaphumeleli kwi-3,000 psi-okanye i-cobalt-alloy pump yezindlu iqhekeza phantsi kwebhayisikili ye-thermal-awudingi "ukulunga ngokwaneleyo" ukucwangciswa. Udinga uzinzo lwe-dimensional ngaphakathi kwe-± 0.005 mm, imfezeko ye-microstructure kwiibhetshi eziphathwa ngobushushu ze-AMS 5387, kunye nokunyamezela i-zero kwizithuba zokulandela umkhondo. Yiyo loo nto iinjineli zaseMntla Melika, eJamani, naseSingapore zichaza iinxalenye ezivela kwi umzi-mveliso womatshini womatshini weCNC ochanekileyo ephatha i-GD&T hayi njengephepha-kodwa njengefiziksi engaxoxisiyo.
Ukuchaneka kwehlabathi lokwenyani kuqala apho ukunyamezelana kuyeka ukuba yithiyori
Siyibone kabini kulo nyaka: umthengisi wezixhobo ze-oyile ye-Tier-1 wala i-47% yeprototype yepiston pump cylinder housings evela kubathengisi abathathu abahlukeneyo-kungekhona ukugqiba umphezulu, kodwa ngenxa yokuba i-concentricity ikhukuliseke ngaphaya kwe-0.012 mm emva konyango lobushushu bokunciphisa uxinzelelo. Oyena nobangela? Ulwakhiwo olungangqinelani lokugalela ukutya okuziinkozo kwimisebenzi ye-CNC. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sisombulula lo msinga ongasentla. Isiseko sethu sokwenziwa kwesanti silawula amaxabiso okuqinisa intsimbi kunye nentsimbi engatyiwa kusetyenziswa imephu ye-thermocouple yexesha lokwenyani-emva koko uqinisekise ibhillet nganye engenayo ngohlalutyo lwespectrographic ngaphambi kokuba kuqale ukusebenza. Akukho ngqikelelo. Akukho ngaphandle kwebhetshi.
Oku kudityaniswa ngokuthe nkqo-ukuphosa, i-multi-axis CNC, unyango lobushushu, kunye nokugqitywa komphezulu phantsi kophahla olulodwa oluhambelana ne-ISO-kuthetha ukuba sibambe ukunyamezela kwejometri * ngokusebenzisa * inkqubo epheleleyo yekhonkco. Umzimba wevalve yoxinzelelo awenziwanga nje ukuzoba; ukucutheka kwayo okuphoswayo kumodareyithwa, ukugqwetheka kwayo emva komatshini kulinganiswe kwi-CMM ye-Zeiss, kunye nokuqina kwayo kokugqibela kuqinisekisiwe ngokuchasene ne-ASTM E18. Sihambisa iinxalenye ezisindayo—kungekhona nje ukuphumelela—kuvavanyo lokuqala loxinzelelo.
Iisuperalloys "ayinzima kumatshini." Abaphathwa kakuhle
Abanye ababoneleli baphatha i-cobalt-nickel alloys njengentsimbi eqinile. Azikho. Amacandelo asekelwe kwi-T800 afuna izicwangciso zendlela yokunciphisa ubushushu-hayi nje isondlo esinamandla. Sisebenzisa i-high-feed milling ene-PCD-tipped cutters kwi-AMS 5387 nozzles, ukugcina ingqibelelo yomhlaba ngaphantsi kwe-Ra 0.4 µm ngelixa ubambe ubukhulu bodonga ukuya ku-±0.008 mm. Kutheni le nto ibalulekile? Ngenxa yokuba ukuhluka kwe-0.015-mm kwiplagi ye-cobalt alloy itshintsha i-coefficient yokuhamba nge-11% kwi-high-pressure hydraulic circuits-kwaye loo nto inokulinganiswa kwiintsilelo zentsimi.
Umgangatho wevenkile yethu uqhuba oomatshini bothotho lwe-DMG MORI NT abanee-axis ezintlanu ezinovavanyo oludibeneyo, kodwa oyena mahluko wokwenyani luqeqesho lwesinyithi. Sisebenzisana nokuphuhlisa imijikelo yokunyanga ukushisa kunye nababoneleli bezinto eziluhlaza abaqinisekisiweyo-ukuqinisekisa ukuba yonke ibhetshi ye-AMS 5387 ibetha ekujoliswe kuko kokuqina (≥1,380 MPa) kunye nobude (≥12%) *phambi kokuba* ukusika kuqale. Xa umthengi esicela ukuba siphindaphinde i-T800 ye-alloy alloy center shaft roller ye-winch yemoto yobunjineli, siye sabuyisela umva i-microstructure yasekuqaleni ngohlalutyo lwe-SEM/EDS-kungekhona nje ukukhutshelwa kwemilinganiselo. Inxalenye iqhube i-32% ixesha elide kwinkonzo kunokutshintshwa kwe-OEM.
Ukuthembeka akuthenjiswa. Yakhelwe kwiiprothokholi zokuhlola
“Ukulandelelwa ngokupheleleyo” kuthetha ngaphezu kwenani elininzi eligximfizwe kwibhokisi. Kuwo onke amacandelo abalulekileyo-i-valve zoxinzelelo, iziseko zempompo, izindlu ze-cylinder-singena: iingxelo zokuvavanya izinto eziluhlaza, ukukhupha iziphumo ze-X-ray, ii-ID zeprogram ye-CNC, iifayile zokulinganisa i-CMM, iitshathi zokushisa zokushisa, kunye namanqaku okugqibela okuhlola okubonakalayo. Yonke idatha igcinwa iminyaka eyi-10. Abathengi bafikelela kwimbali yabo yeprojekthi nge-portal ekhuselekileyo-hayi iiPDF ezithunyelwe nge-imeyile ezinzulwini zobusuku.
Kodwa uqinisekiso lwenzeka *ngexesha* lemveliso-hayi nje ekugqibeleni. Abasebenzisi benza uhlolo lwenkqubo besebenzisa izithelekisi zokukhanya kwiifitsha ezifana nombhobho orifice geometry. Yonke inxalenye yesithathu idlula uhlolo olupheleleyo lweCMM ngokuchasene nefayile ye-STEP yokuqala-kungekhona nje imilinganiselo engundoqo. Kwaye ewe-siyaqinisekisa ii-callouts ze-GD&T njengesikhundla, iprofayile, kunye nokuqhutywa *kumxholo*, hayi njengeempawu ezizimeleyo. Ukuba umzobo wakho uxela ukunyamezelana okudityanisiweyo kobuso beflange xa kuthelekiswa ne-axis ebhobhozayo, silinganisa ngolo hlobo-sisebenzisa izifanisi zedatum eziphindaphinda iimeko zokoqobo zendibano.
Ixesha lakho akufuneki lixhomekeke kwisicwangciso samandla oboneleli
Iiodolo zomthamo ophakathi (ama-50–500 ii-pcs) zihlala zizinzile kwiifektri ezilungiselelwe iiprototypes okanye imveliso yobuninzi. Sakhe ukuhamba komsebenzi wethu kumhlaba ophakathi: uyilo lweeseli ezibhityileyo, ukulungiswa okusemgangathweni kwiintsapho zamalungu epompo, kunye nesitokhwe se-buffer se-cobalt eqhelekileyo kunye namabanga angenasici. Xa i-OEM yempompo yaseYurophu yayidinga iinxalenye zempompo ze-120 AMS 5387 kwiintsuku ezili-18-emva kokuba umthengisi wazo wangaphambili ephoswe ngumhla wokugqibela ngeentsuku ezingama-37-sahambisa ngosuku lwe-17. Hayi ngeempelaveki zokusebenza. Ngokususa iilophu zokuphinda zisebenze: ukuphosa i-porosity ebanjwe kwangaphambili, ukunxitywa kwesixhobo kuhlolwa ngexesha lokwenyani, kunye nokuhlolwa kokugqibela ngaphambi kokupakishwa.
Oko kuthembeka kunabela kwinkxaso yobunjineli. Asicaphuli nje imizobo—sifaka iflegi yomngcipheko wokwenziwa *ngaphambi kokuba* sicaphule: “Olu donga luyi-0.3 mm kwizindlu zevalvu luza kuphambuka xa ubambene; cebisa ukuba kongezwe iimbambo zethutyana.” Okanye: "I-Ra 0.2 µm echaziweyo yokugqiba ifuna i-electropolishing-hayi ukugaya-eyongeza iintsuku ezi-3 kodwa ithintele ukuqaliswa kwe-micro-crack." Akukho nto imangalisayo. Izigqibo nje ezisekelwe kwiminyaka eli-12 yokwenza amacandelo amashishini aphezulu.
Kwimishini yentsimbi ebalulekileyo-apho ukusilela kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye amabango ewaranti-ukuchaneka akuyobhokisi yokujonga iphepha. Yindlela olawula ngayo ubume beenkozo, ulawule ukugqwethwa kobushushu, kwaye unyanzelise ukuqhubeka komda phakathi kokusa, ukwenziwa, kunye nokugqiba. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza njenge umzi-mveliso womatshini womatshini weCNC ochanekileyo kuba iphatha yonke i-micron njengemfuneko esebenzayo-kungekhona ekujoliswe kuyo. Icandelo lakho elilandelayo elintsonkothileyo alifuni enye isicatshulwa. Ifuna iqabane elilinganisa impumelelo kwixesha lokusebenza, hayi nje ukuhanjiswa kwexesha.
