Pamene makina a hydraulic akulephera pansi pa 350-bar pressure, wolakwayo nthawi zambiri sakhala mpope-ndi gawo la homogenizing valve. Taziwona katatu chaka chino chokha: kusuntha kosagwirizana, kuphulika kwa kutentha pambuyo pa kuzungulira kwa 420, kukokoloka kwa mipando isanakwane mu nozzles za cobalt-alloy. Kulephera kulikonse kunayambira pa chifukwa chimodzi—kusakhazikika kwapang'onopang'ono pazigawo za aloyi za T800 zotenthetsera. Ichi ndichifukwa chake mainjiniya amafufuza Homogenizing Valve gawo fakitale abwenzi samafunsa "Kodi mungathe?" Amafunsa "Kodi mutha kugwira ± 0.015 mm pa 220 mm bore ndikusunga umphumphu wa AMS 5387 microstructure kudzera pakupumula komaliza?"
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imayankha funso limenelo ndi chilango chotsatira—osati malonjezo. Kutengera ku Qingdao, kampaniyo imagwiritsa ntchito malo ogwirizana ndi ISO pomwe kuponyera, kukonza makina a CNC, ndi kumaliza sizinthu zotsatizana - ndi magawo olumikizana pansi pa loop imodzi yotsatirika. Wogula akatumiza chojambula cholemera cha GD&T cha nyumba ya silinda ya pampu ya piston, mainjiniya samangoyang'ana kulolerana. Amatengera njira zokhotakhota, kutsimikizira kutha kwa nkhungu polimbana ndi makulidwe akumakoma, ndikuwonetsetsatu ngozi zakugunda kwa zida pamakina enieni a 5-asanadule chitsulo choyamba.
Zowona zitatu zaukadaulo zimasiyanitsa izi Homogenizing Valve gawo fakitale kuchokera kwa ma suppliers acholinga chonse:
- Cobalt-nickel alloy mastery sizongopeka - zimasinthidwa. Zigawo za AMS 5387 zimapatsidwa chithandizo cha kutentha kwapawiri (njira yothetsera pa 1175 ° C + kukalamba pa 845 ° C), ndi ma thermocouples a ng'anjo opangidwa ndi ± 1.2 ° C kudutsa 1.8 m³ zone. Gulu lililonse limatsimikiziridwa ndi mawonekedwe - palibe "satifiketi yazinthu zomwe zimaganiziridwa."
- Dimensional control imayamba musanayambe kupanga makina. Kuponyera chitsulo pamaziko a pampu kumagwiritsa ntchito makina okwera oziziritsa omwe amachepetsa kupsinjika kotsalira ndi 38% motsutsana ndi geting wamba-kuyezedwa kudzera pa X-ray diffraction pama cores, osayerekezedwa.
- Kukhazikika kwapamwamba kumafanana ndi kufunikira kwa magwiridwe antchito. Mpando wa vavu wa homogenizing sufuna Ra 0.4 µm paliponse-umafunika Ra 0.2 µm pa bandi yosindikizira, Ra 1.6 µm pa popopopopokera, komanso kupanikizika kotsalira kotsalira (−320 MPa) mkati mwa kuya kwa 0.15 mm pansi pa nthaka. Izi zimatheka ndi kutsirizitsa kosakanizidwa: kupukuta molondola kumatsatiridwa ndi kuwomberedwa kwa mphamvu zochepa, kutsimikiziridwa ndi mizere ya Almen ndi magawo a SEM.
Ena angatsutse kuti kuphatikizika kwa makina opangira zida zam'nyanja kumapangitsa kuti pakhale kusamvana kapena zolembera. Koma m'machitidwe, tatsata madongosolo 17 aku North America ndi misika ya EU-ndipo kuwunika kulikonse kwaumisiri kumaphatikizapo kugawana zenizeni zenizeni za malipoti a CMM omwe ali pamitundu ya CAD, zofotokozera za GD&T zolembedwa nthawi. Ayi "tifotokoza pambuyo pake." Ayi "molingana ndi kumvetsetsa kwathu." Ingotsimikizirani zenizeni: "Kupatuka kwa kutsika kwa 0.02 mm uku kumatuluka kunja kwa zomwe mukufuna - nayi mapu akuwonetsa chifukwa chake, ndipo nayi mapangidwe athu okonzedwanso kuti akonze."
Zotsatira zimawonekera pakuchita masewera. Makasitomala m'modzi waku Southeast Asia adalowa m'malo mwa ma valavu omwe adalephera kugwira ntchito maola 14,000 ndi mtundu wa QIANGSENYUAN wa T800 alloy. Pambuyo pa maola 28,500-pansi pa 290 ° C mosalekeza, ntchito ya 310-bar-mayunitsi adadutsa kuyang'aniridwa ndi akupanga ndi ziro subsurface discontinuities. Osati "akugwirabe ntchito." Zotsimikizika zonse. Kudalirika kumeneko kumachokera ku kuphatikiza koyima: gulu lomwelo limasankha ingot ya cobalt, imataya kanthu, imayika ma port geometry, ndikuyika zokutira komaliza kwa nitride. Palibe kuperekedwa kumatanthauza kuti palibe kusinthika kobisika-palibe kukula kosalamulirika kwa njere panthawi yakusamutsa pakati pa malo, palibe kuipitsidwa kwapamtunda kosalemba musanaphike.
Kwa magulu ogula zinthu akuwunika a Homogenizing Valve gawo fakitale, yambani ndi mafunso atatu: Choyamba, kodi angakuwonetseni malipoti oyezetsa mphero *pa nambala yanu yeniyeni ya oda*—osati ma cert a generic? Chachiwiri, kodi malipoti awo a CMM akuphatikiza kuwunika kwathunthu kwa GD&T (osati "OK / NG" kupitilira / kulephera)? Chachitatu, ndi njira yotani yomwe adalembedwa yochitira zinthu zomwe sizinafanane pakati pa ntchito - kukonzanso, zotsalira, kapena kusiya mainjiniya? QINGDAO QIANGSENYUAN amasindikiza onse atatu pa pempho. Njira yawo sikutanthauza kupewa kulephera. Zimakhudza kupanga kuzindikira mu gawo lililonse-kotero kupatuka kwa 0.008 mm kukawoneka mkati, kumayambitsa kuwunikanso kwazitsulo -osati kudandaula kwamakasitomala atatumiza.
Kuyang'ana m'tsogolo, vuto silikulitsa zotuluka - ndikukulitsa kulondola kwa magwiridwe antchito. Gawo lotsatira la R&D limayang'ana kwambiri njira zosakanizidwa: ma valavu oponyera ndalama omwe ali ndi njira zoziziritsira zophatikizika zamakina, pomwe kayeseleledwe ka kutentha kumayendetsa mapangidwe a nkhungu ndi kutsatizana kwa zida za CNC. Cholinga? Gwirani cylindricity ya 0.01 mm pa 300 mm mainchesi popanda kuwongoleredwa pambuyo pa kutentha. Kumeneko sikuli kowonjezera. Ndiko kutanthauziranso zomwe "kuchita bwino kwambiri" kumatanthauza mavavu a homogenizing-micron imodzi yovomerezeka panthawi imodzi.
