Pamene mainjiniya amatchula a cpp Investment casting fakitale, sakungoyang'ana maziko ena-akufunafuna kukhazikika kwapang'onopang'ono pansi pa njinga yamoto yotentha, microstructural consistency mu AMS 5387 cobalt alloy, ndi zero tolerance for porosity mu pump cylinder housings ovotera 400+ bar. Izi ndizochitika zenizeni zomwe timaziwona tsiku ndi tsiku ku Qingdao Qiangsenyuan Technology Co., Ltd.-malo omwe kuponya ndalama si njira yokhayokha koma yolumikizidwa mwamphamvu ndi makina a CNC amitundu yambiri, kukonza kutentha, komanso kuyang'anira koyendetsedwa ndi GD&T.
Chifukwa chiyani "CPP" Imatanthauza Zambiri Kuposa Chidule Chachidule
"CPP" imayimira *Cobalt-Precision-Pump*-osati chizindikiro cha malonda, koma katatu yogwira ntchito yophatikizidwa mu dongosolo lililonse. Tawona makasitomala akutumiza zojambula zolembedwa "AMS 5387, RMA 40, ± 0.02 mm" kuti tipeze zapakatikati kuti kapangidwe kawo koyambirira sikunapangitse kuchepa kwamphamvu m'matupi amphuno opyapyala. Ndipamene CPP imasintha kuchoka ku chidule kupita kuchitapo kanthu: akatswiri athu a metallurgists amasintha geometry geometry; makina athu amatsatizananso zomaliza kuti asunge umphumphu wa pamwamba; gulu lathu la QA limatsimikizira kuuma kwa ma gradients kudera lomwe lakhudzidwa ndi kutentha-osati kumtunda kokha.
Izi sizongoyerekeza. Chaka chatha, European hydraulic OEM idatitumizira nyumba yopopera pisitoni yokhala ndi ziboliboli zitatu zodutsana, chilichonse chimafuna kumaliza kosiyanasiyana (Ra 0.4 µm pankhope zosindikiza, Ra 1.6 µm pamalo okwera). Zochita zokhazikika zikadakhala kuponya zovuta, kenako makina onse. M'malo mwake, tidagwiritsa ntchito njira yopangira ndalama kuti tipereke mawonekedwe oyandikira ukonde pamabowo awiri - ndikungopanga chachitatu, pomwe kulolerana kolimba kumagwiritsidwa ntchito. Nthawi yozungulira yatsika ndi 37%. Chiwongola dzanja chatsika kuchoka pa 11% kufika pa 1.8%.
Maluso Anayi Omwe Amaphatikizana
Otsatsa ambiri amalemba "casting + Machining + finishing" ngati ntchito zosiyana. Pamalo athu a Qingdao, ntchitozo zimagawana nkhokwe zosungiramo zida, zolemba zakale zamafuta, ndi ma CMM probe calibration schedule. Umu ndi momwe zimagwirira ntchito:
- Kuwongolera koponya kumayamba musanathire: Timatsimikizira ma certs opangira T800 aloyi motsutsana ndi ASTM A992-kenako fufuzani zowunikira motsutsana ndi malipoti a gulu la ogulitsa. Palibe kuchotserapo.
- Machining amalipira kusiyanasiyana kwa kuponyera: Miyendo yathu ya Haas VF-6 imagwiritsa ntchito chipukuta misozi cha nthawi yeniyeni, yodyetsedwa ndi kusanthula kwa laser kwa zinthu zofunika kwambiri za datum-kotero ngati kuponyera kumadutsa 0.015 mm oversize pa nkhope ya flange, mpheroyo imasintha mozama-kudula basi.
- Chithandizo cha kutentha chimakonzedwa-osati kuwonjezeredwa: Pamene pulagi ya aloyi ya cobalt imafuna njira yothetsera pa 1150 ° C ± 5 ° C, sitimapereka kunja. Ng'anjo yathu ya vacuum imasunga kuwerenga kulikonse kwa thermocouple, ndipo deta imalumikizana mwachindunji ndi mapasa a digito mu MES yathu.
- Kumaliza machesi ntchito, osati masamba enieni: Winch center shaft roller safuna yunifolomu Ra 0.8 kudutsa kutalika kwake konse-kokha pa 42 mm contact band. Timaphimba madera osafunikira ndikuyika electro-polilish mosankha.
Zomwe Makasitomala Amayesa - Osati Zomwe Ma Datasheets Amanena
Ena amafunsa kuti: "Kodi mungagwire ± 0.015 mm pa 320 mm cobalt alloy valve body?" Inde, koma pokhapokha ngati chojambulacho chikufotokozera muyeso wofananira ndi mawonekedwe a as-cast datum, osati chiyambi cha CAD. Ena amaganiza kuti "chitsulo chosapanga dzimbiri" amatanthauza 316L. Koma muzakudya zopatsa mphamvu kwambiri zamafuta & gasi, timasintha ku CF8M pokhapokha ngati tauzidwa mwanjira ina - chifukwa zomwe zili mu ferrite zimawongolera kupsinjika kwa dzimbiri komwe kumakhala kowawa.
Takhala ndi makasitomala atatu aku North America omwe abwereranso - osati chifukwa chakulephera kwapang'onopang'ono, koma chifukwa cholumikizira cholumikizira chamaloboti chidatsika pamwamba pomwe chinakumana ndi ma Ra specs koma chinalibe mawonekedwe ang'onoang'ono ofunikira kuti agwirizane. Tsopano, tikuphatikiza ma scan a profilometer mu phukusi lililonse la PPAP la zida zonyamula katundu. Osasankha. Zosakambirana.
Kumene Kulondola Kumakumana ndi Kutumiza Kothandiza
A zoona cpp Investment casting fakitale ayenera kulinganiza kukhwima kwa metallurgical ndi chilango cha kupanga. Izi zikutanthauza kukhala ndi certification ya ISO 9001:2015 ndikuwunikanso zatsiku ndi tsiku za kaizen pamitengo yobweza mchenga m'dipatimenti yathu yazachuma-kapena kutsatira zokolola zoyambira pa AMS 5387 ma nozzles pamatenthedwe asanu motsatizana kuti muwone zolakwika pakugawa kukula kwambewu.
Timatumizira makasitomala kuchokera ku Hamburg kupita ku Houston kupita ku Ho Chi Minh City, osati kudzera mwa ogulitsa, koma kudzera muunikani waukadaulo wachindunji. Mawu aliwonse amaphatikizanso mayankho opangira: "Fillet radius iyi igwira zotsalira za ceramic - imalimbikitsa R1.2 min." "Mabowo osawonawa amapitilira malire a chiwongolero cha zipolopolo zotulutsa mpweya - perekani bowo lokhala ndi pulagi." Palibe mawu. Palibe kupatuka. Zomwe zingatheke, zoperekedwa mkati mwa maola 72.
Kuyang'ana m'tsogolo, kuyang'ana kwathu kumakhalabe kocheperako: luso lozama la makina a faifi tambala wa cobalt, kuphatikiza kolimba pakati pa kayeseleledwe ka makina opangira zida za CNC, ndikukulitsa kuchuluka kwa AS9100 pamisonkhano yamapampu amlengalenga. Chifukwa kulondola sikuyezedwa mu ma microns okha - kumatsimikiziridwa mu nthawi, kubwereza kubwereza, ndi chidaliro chabata cha injiniya yemwe amadziwa bwino zomwe zimachitika T800 yosungunuka ikagunda nkhungu.
