Xa iinjineli zichaza amacandelo ensimbi engenasici kwiivalvu zehydraulic, izindlu zempompo, okanye i-winch shafts, abakhethi nje izinto eziphathekayo-babheja kwi-dimensional stability phantsi koxinzelelo lwe-300-bar, ukuxhathisa ukubola kwiindawo ezingaselunxwemeni ezigcwele ityuwa, kunye nokunyaniseka kwe-microstructural emva konyango lobushushu. Yiyo loo nto ukhetha okulungileyo steel stainless components factory ayikho malunga nexabiso ngekhilogram. Imalunga nenkqubo yoluleko, ukulandeleka kwe-metallurgical, kunye nesakhono esiqinisekisiweyo nge-AMS 5387 cobalt alloys, T800 superalloys, kunye nokuchaneka-cast 17-4PH okanye F22 duplex izindlu.
Imingeni yobumatshini bokwenyani ifuna ngaphezulu koomatshini be-CNC
Siye sabona iiprojekthi ezininzi kakhulu zivaliwe kwinqanaba le-prototype-kungekhona ngenxa yokuba uyilo aluphumelelanga, kodwa ngenxa yokuba umthengisi akakwazanga ukubamba i-± 0.015 mm kwizindlu ze-piston pump cylinder ezineentambo zangaphakathi eziphazamisekileyo kunye neendlela zokupholisa ezinqabileyo ezinqabileyo. I-standard stainless steel machining isebenza kwizibiyeli kunye neeflange. Kodwa iindawo ezibalulekileyo ze-mission-ezifana neevalvu zoxinzelelo ezisebenza kwi-120 ° C kwi-oyile kunye ne-gas skids okanye i-shaft rollers ye-shaft ye-winch yeemoto zobunjineli-zifuna ulawulo oludibeneyo lokuphosa. Awungekhe ukhuphe ukukhutshwa kwesanti kumthengisi omnye, ukuphatha ubushushu komnye, emva koko unikezele kwisithathu ukugqiba i-axis eninzi. Ukugqwetheka kobushushu kuyangena. I-Dimensional drift iyaqokelelana.
Yingakho ukuhlanganiswa okuthe nkqo kubalulekile: ukulawula ikhonkco elipheleleyo-ukusuka kwi-316L eqinisekisiweyo okanye i-F51 yokuqinisekisa isitokhwe sebha ekrwada, ngokuphosa utyalo-mali lwemibhobho entsonkothileyo, ukuya kwi-5-axis milling yeendawo zokutywina kunye nokugqithwa kokugqibela-ukuqinisekisa iipropathi zomatshini eziphindaphindwayo. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke iplagi yealloyi yecobalt iqala ngebhetshi eqinisekisiweyo ye-T800 ingot. Yonke insimbi engenasici ihlalutya i-spectral ngaphambi kokugalelwa. Akukho ngaphandle.
I-AMS 5387 kunye ne-T800 ayingomanani akhethekileyo-ngamanqaku okusilela alindele ukwenzeka.
Abanye ababoneleli bacaphula "i-cobalt alloy" ngaphandle kokuchaza ibakala. Oko kuyingozi. I-AMS 5387 i-cobalt alloy 6 ihambisa ubunzima obuthile (38-45 HRC), ukuhambelana nokwandiswa kwe-thermal (12.5 × 10⁻⁶ / ° C), kunye nokumelana nokukhukuliseka kweendlela ze-high-velocity fluid. I-T800 iqhubela phambili-yenzelwe amaqondo okushisa ukuya kwi-800 ° C, kunye nokumelana nokunyuka okubalulekileyo kwiindibano zempompo ye-turbine. Kodwa ezi alloys machine kwi 1/3 izinga feed of 304 stainless. Isixhobo sokunxiba izikhonkwane. Umphezulu wemfezeko uyawohloka ukuba uxinzelelo lwesipholisi lwehla ngaphantsi kwe-70 bar okanye ukuqina kwe-spindle kuncipha.
Siyilinganisile: ukulandelelana kwendlela yesixhobo engalawulekiyo kwi-AMS 5387 nozzle kubangele i-microcracking engaphantsi komhlaba ibonakala kuphela phantsi kwe-SEM. Inxalenye iphumelele iitshekhi ze-dimensional-kodwa ayiphumelelanga uvavanyo lokuqhuma kwi-92% yoxinzelelo olulinganisiweyo. Ikhono lokwenyani lithetha ukuqhuba amathala eencwadi ezixhobo eziqinisekisiweyo, ukubeka iliso amandla okusika ngexesha lokwenyani, kunye nokulungelelanisa uburhabaxa bomphezulu (Ra ≤ 0.4 µm) kunye nobomi obusebenzayo bokudinwa. Oko akunakuxoxisana kumacandelo ensimbi engenasici kumahlakani efektri aphatha iinxalenye zempompo yomgangatho we-aerospace.
Umgangatho awuhlolisiswanga-yakhiwe, ngokulandelelana
“Isiqinisekiso se-ISO” sithetha kancinci ngaphandle kokuba ubona indlela esebenza ngayo yonke imihla. Kwesi sibonelelo, iibhilithi zentsimbi ezingenastainless ezingenayo zifumana ukuqinisekiswa kabini: I-PMI spectroscopy + iikhuphoni zokuvavanya ubushushu obuvela kubushushu ngamnye. Ngexesha lomatshini, ukuhlolwa kwe-CMM kwenzeka emva kokugqithisa, ukugqitywa kwesiqingatha, kunye nokupasa kokugqibela-kungekhona nje ekupheleni. Izithukuthezi ezibalulekileyo? Ilinganisa ngeegeyiji zomoya ezilinganiswa yonke imihla. Iifom zomsonto? Iqinisekiswe ngeprofilometers yamehlo, hayi iiplagi zomsonto zodwa.
Ukulandeleka ayingomaphepha-ziikhowudi ze-QR ezifakwe ngelaser kuwo wonke umzimba wevalvu onxibelelanisa nelogi yawo yokuqala yokunyibilika, igophe lonyango lobushushu, kunye nengxelo yokugqibela yokuhlola. Xa i-OEM yaseYurophu icele ukuqinisekiswa kwe-GD&T kwisiseko sempompo esingesiso esiqhelekileyo, iqela lizise imizobo echazayo ebonisa kanye apho iithagethi zedatum zazisekwe khona ngokwasemzimbeni ekujuleni-kwaye kutheni ezo ndawo zicutha ukuphambuka okubangelwa yi-clamping ngexesha lokugqiba machining. Elo nqanaba lokungafihli linciphisa iindleko ze-NRE ngama-30% ngokomndilili.
Ukuthembeka kuqala ixesha elide ngaphambi kokuba inxalenye yokuqala ihambe
Unikezelo olungaguquguqukiyo luxhomekeke kwizinto ezintathu: amakhonkco obonelelo ngemathiriyeli ekrwada ezinzileyo, amaxesha okuqikelelwa komjikelo, kunye nengxelo yokwenziwa kwangaphambili. Sincede abathengi banqande ukuyilwa ngokutsha ngokufaka iflegi yoguquko olunobungqingqwa bodonga oluya kubangela ukucutheka kwe-porosity kwi-17-4PH castings-okanye ukuchonga ii-callouts ze-GD&T ezifuna i-gaging yesiko ngaphaya kwamandla aqhelekileyo eCMM. Ayisiyiyo "inkxaso yobunjineli." Kukunciphisa umngcipheko owakhelwe kwinqanaba lokucaphula.
Kubathengi abafumana izinto zentsimbi engenasici kwiimarike zehlabathi-nokuba ngabadibanisi benkqubo yokwenziwa koxinzelelo lwendalo yaseMntla Melika, ii-OEMs zempompo zaseJamani, okanye abakhi bezixhobo zaselwandle zaseMazantsi-mpuma eAsia-ixabiso lisemandleni okuphindaphindwa ngokuphindaphindiweyo kuzo zonke iibhetshi, hayi elona xabiso liphantsi leyunithi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. igxininisa kwinto ehambisa inaliti: ukuhambelana kwe-metallurgical, ukunyaniseka kwejometri kwiikhonto eziyinkimbinkimbi, kunye ne-zero compromises kwi-traceability. Kuba xa icandelo lakho litywina i-300-bar yoxinzelelo, akukho thuba lesibini.
