Xa iinjineli zichaza a Umzi mveliso wotyalo-mali we-cpp, abakhangeli nje enye isiseko-bafuna ukuzinza kwe-dimensional phantsi kwebhayisikili ye-thermal, i-microstructural consistency kwi-AMS 5387 cobalt alloy, kunye ne-zero tolerance for porosity in pump cylinder housings rated for 400 + bar. Leyo yinyani yokusebenza esiyibona mihla le e-Qingdao Qiangsenyuan Technology Co., Ltd-indawo apho ukutyalwa kotyalo-mali kungeyonkqubo ezimeleyo kodwa enye idityaniswe ngokuqinileyo nomatshini we-CNC we-multi-axis, ukucwangciswa konyango lobushushu, kunye nohlolo oluqhutywa yi-GD&T.
Kutheni "i-CPP" ithetha Ngakumbi kunesifinyezo nje
"I-CPP" imele * i-Cobalt-Precision-Pump * -kungekhona i-tagline yokuthengisa, kodwa i-triad esebenzayo efakwe kuyo yonke i-oda. Siye sabona abathengi bethumela imizobo ebhalwe “AMS 5387, RMA 40, ±0.02 mm” kuphela ukufumanisa imveliso esembindini ukuba uyilo lwabo lwantlandlolo aluzange luthathele ingqalelo ukuqina kokuqina kwimizimba yomlomo obhityileyo. Kulapho i-CPP itshintsha ukusuka kwisifinyezo ukuya kwisenzo: i-metallurgists yethu ilungisa i-geometry yokujonga; oomatshini bethu baphinda balandelelanise ukugqibezela ukusikeka ukuze bagcine ingqibelelo yomphezulu womhlaba; Iqela lethu le-QA liqinisekisa ubunzima bobunzima kuyo yonke indawo echatshazelwe bubushushu hayi nje kumphezulu.
Oku akuyothiyori. Kulo nyaka uphelileyo, i-OEM ye-hydraulic yaseYurophu isithumelele impompo yepiston yendlu enebhore ezintathu ezingenelayo, nganye ifuna ukugqitywa komphezulu okwahlukileyo (iRa 0.4 µm ebusweni bokutywina, iRa 1.6 µm kwindawo enyukayo). Ukuziqhelanisa okusemgangathweni kuya kuba kukuphosa, emva koko umatshini yonke into. Endaweni yoko, sasebenzisa utyalo-mali ukuhambisa imilo ekufutshane nenetha kwiibhore ezimbini-kwaye sasebenza ngoomatshini kuphela okwesithathu, apho kunyamezelwa kakhulu. Ixesha lomjikelo lehle ngama-37%. Izinga le-Scrap lehle ukusuka kwi-11% ukuya kwi-1.8%.
Izakhono ezine ezithi Ngenene Zinxibelelane
Ababoneleli abaninzi badwelisa "ukuphosa + machining + ukugqiba" njengeenkonzo ezahlukeneyo. Kwiziko lethu le-Qingdao, loo misebenzi yabelana ngogcino-lwazi lwezixhobo, iilogi zembali eshushu, kunye neshedyuli yokulinganisa i-CMM. Nantsi indlela esebenza ngayo:
- Ulawulo lokuphosa luqala phambi kokugalela: Siqinisekisa iicerts zemathiriyeli ekrwada ye-T800 ingxubevange ngokuchasene ne-ASTM A992-emva koko jonga uhlalutyo lwe-spectral ngokuchasene neengxelo zebhetshi yababoneleli. Akukho ngaphandle.
- Umatshini ubuyekeza ukwahluka kokuphosa: Iinqwelo zethu ze-Haas VF-6 zisebenzisa i-real-time tool imbuyekezo, zondliwa yi-in-process laser scanning ye-datum ebalulekileyo yeempawu-ngoko ke ukuba i-casting iqhuba i-0.015 mm ngokugqithisileyo ebusweni be-flange, i-mill ilungisa i-deep-cut-cut ngokuzenzekelayo.
- Unyango lobushushu lucwangcisiwe-alufakwa: Xa iplagi ye-cobalt alloy ifuna isisombululo se-annealing kwi-1150 ° C ± 5 ° C, asiyi kuphuma ngaphandle. Isithando somlilo sethu sigcina lonke ukufundwa kwe-thermocouple, kwaye idatha ivumelanisa ngokuthe ngqo kwiwele ledijithali kwi-MES yethu.
- Umsebenzi wokugqibezela iimatshisi, hayi amaphepha athile: I-winch center shaft roller ayifuni i-uniform Ra 0.8 kulo lonke ubude bayo obupheleleyo-kuphela kwi-42 mm yoqhagamshelwano loqhagamshelwano. Sifihla iindawo ezingabalulekanga kwaye sisebenzise i-electro-polish ngokukhetha.
Yintoni ngokwenene abaVavanyayo abaThengi-hayi eyona nto ibango leDatasheets
Abanye bayabuza: “Ngaba unokubamba u-±0.015 mm kumzimba wevalve ye-cobalt eyi-320 mm?” Ewe-kodwa kuphela ukuba umzobo uchaza isiseko sokulinganisa ngokumalunga nesakhiwo sedatum njenge-cast, kungekhona imvelaphi ye-CAD yethiyori. Abanye bacinga ukuba "insimbi engenasici" ithetha i-316L. Kodwa kuxinzelelo oluphezulu lweoyile kunye nenkonzo yerhasi, siyasilela kwi-CF8M ngaphandle kokuba sixelelwe ngenye indlela-kuba umxholo wayo we-ferrite ulawula ukuxhathisa kokuqhekeka kwe-corrosion kwindawo emuncu.
Siye saba nabathengi abathathu baseMntla Melika ababuyayo-hayi ngenxa yokungaphumeleli komda, kodwa ngenxa yokuba i-robotic gripper yomgca wabo wendibano yatyibilika kumphezulu odibene ne-Ra specs kodwa ingenawo umzobo ofunekayo we-coefficient of friction. Ngoku, sibandakanya iskeni seprofilometer kuyo yonke iphakheji yePPAP yezinto ezithwala umthwalo. Ayikhethi. Akuxoxiswana.
Apho Ukuchaneka Kudibana Ukuhanjiswa OkuSebenzayo
Yinyani Umzi mveliso wotyalo-mali we-cpp kufuneka ilungelelanise ubungqongqo be-metallurgical kunye noqeqesho lwemveliso. Oko kuthetha ukubamba isatifikethi se-ISO 9001:2015 ngelixa sikwaqhuba uphononongo lwemihla ngemihla lwe-kaizen kwireyithi yokubuyiselwa kwesanti kwisebe lethu leqokobhe lotyalo-mali-okanye ukulandelela isivuno sokuqala kwi-AMS 5387 imilomo kwiishushu ezilandelelanayo ukuze ubone ukutenxa okuchuliweyo kubungakanani bokutya okuziinkozo.
Sisebenzela abathengi ukusuka eHamburg ukuya eHouston ukuya kwisiXeko saseHo Chi Minh-hayi ngabasasazi, kodwa ngokuphononongwa kobunjineli ngokuthe ngqo. Isicaphulo ngasinye siquka impendulo yokwenziwa kokwenziwa: "Le fillet radius iya kubambisa intsalela yeceramic- cebisa i-R1.2 min." "Le mingxunya ingaboniyo idlula imida yomlinganiselo wokuvula iqokobhe lokungunda-cebisa umngxuma ngeplagi." Akukho jargon. Akukho phambuko. Igalelo elinokusetyenzwa nje, liziswe kwiiyure ezingama-72.
Ukujonga phambili, ugxininiso lwethu luhlala lumxinwa: ubunzulu benkqubo ye-cobalt-nickel, ukudibanisa okuqina phakathi kokulinganisa kunye nokuveliswa kwendlela yesixhobo ye-CNC, kunye nokwandisa umda we-AS9100 weendibano zempompo ze-aerospace-grade. Ngenxa yokuba ukuchaneka akulinganiswa kwii-microns zodwa-kungqinwa ngexesha, ukuphindaphinda ii-odolo, kunye nokuzithemba okuthe cwaka kwenjineli eyazi kakuhle ukuba kwenzeka ntoni xa i-T800 etyhidiweyo ibetha i-mold.
