Thaum engineers qhia dej iav casting Hoobkas cov kev pabcuam rau cov khoom hlau uas muaj kev ntseeg siab, lawv tsis yog tab tom nrhiav rau lub hauv paus-lawv tab tom nrhiav kev tswj qhov loj me, microstructural zoo ib yam, thiab kev ntseeg siab ntawm metallurgical nyob rau hauv siab. Peb tau pom ntau txoj haujlwm qeeb los ntawm qhov kev cia siab tsis sib haum: ib feem uas dhau qhov ntsuas qhov ntsuas tab sis ua tsis tau zoo thermal cycling, los yog cobalt alloy vaj tsev uas ua tau raws li cov ntawv luam tawm tsis tau tawg thaum kuaj hydraulic. Lub hauv paus ua rau? Fragmented muaj peev xwm-foundries yam tsis muaj machining tswj, tshuab khw tsis muaj kev pom zoo, lossis cov neeg muag khoom uas kho AMS 5387 lossis T800 raws li cov khoom lag luam ntau dua li cov khoom siv tseem ceeb.
Vim li cas dej iav casting tseem ceeb - thiab yog vim li cas nws tsis tshua ua tau zoo
Cov iav dej (sodium silicate) peev casting muab kev tiv thaiv nruj dua li cov xuab zeb casting thiab cov cuab yeej siv qis dua li ceramic plhaub rau nruab nrab-complexity, nruab nrab ntim cov khoom lag luam. Tab sis kev vam meej hinges ntawm peb yam uas tsis yog sib tham: meej slurry rheology tswj, tswj dewaxing kom tsis txhob muaj pwm tawg, thiab rauv ramp profiles calibrated rau txhua alloy lub thermal expansion nkhaus. Hauv peb lub khw, peb kho qhov sib piv-rau-hmoov hauv lub sijhawm raws li cov av noo-tsis yog los ntawm daim ntawv SOP zoo li qub. Rau cobalt-nickel alloys zoo li AMS 5387, txawm tias 2 ° C sib txawv thaum lub sij hawm ua ntej tuaj yeem ua rau micro-shrinkage nyob rau hauv nyias-walled twj tso kua mis. Tias yog vim li cas peb saib xyuas txhua qhov yaj nrog dual-thermocouple arrays thiab teev cov keeb kwm thermal ib ntau - tsis yog ib pawg.
Kev sib koom ua ke ntsug tsis yog lo lus buzz-nws yog tib txoj hauv kev los tuav GD&T
Lub siab valve lub cev cam khwb cia hauv dej iav tuaj yeem nqa ± 0.1 hli linear kam rau ua - tab sis yog tias CNC ua haujlwm uas tshuab nws lub ntsej muag sealing tsis muaj cov lus qhia ncaj qha los ntawm cov txheej txheem casting, koj yuav caum dhau tsib qhov teeb tsa. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., casting, kho cua sov, thiab multi-axis machining qhia ib qho kev ntsuas ntsuas. Peb CMM validates as-cam khwb cia geometry ua ntej rough machining; optical profileometers txheeb xyuas qhov tseeb ntawm qhov chaw tom qab qhov kawg dhau; thiab txhua lub piston twj tso kua mis lub tog raj kheej lub tsev nyob dhau qhov kev sim ua haujlwm hydrostatic ntawm 1.5 × ntsuas kev ua haujlwm siab - tsis yog tsuas yog kuaj xyuas. Qhov no tshem tawm qhov "black box" handoff ntawm departments. Thaum ib tus neeg siv khoom xa tuaj rau peb GD & T-hnyav daim duab rau lub tsheb engineering tsheb winch center ncej rau cov menyuam, peb tau tshaj tawm ob daim ntawv hu xov tooj uas tsis sib haum xeeb nrog cov tub ntxhais rub kev taw qhia - ua ntej pib siv. Qhov ntawd tau cawm peb lub lis piam thiab $ 18,000 hauv kev rov ua haujlwm dua.
Kev qhuab qhia ntawm cov khoom sib cais precision casting los ntawm cov khoom tsim
Cobalt alloy nozzles tsis poob vim yog kev ua haujlwm tsis zoo. Lawv ua tsis tiav vim qhov tsis sib xws ntawm carbide faib thoob plaws ntu. Peb muab T800 thiab AMS 5387 ingots nrog tag nrho cov ntawv pov thawj zeb-xws li spectrographic tsom xam, grain loj cov ntaub ntawv, thiab tensile nkhaus ib ASTM E8. Txhua qhov cua sov yog cais, tag nrog QR-coded traceability phaib, thiab khaws cia rau hauv cov chaw tswj huab cua. Yog tias ib pawg qhia pom cov ntsiab lus sulfur siab tshaj 0.015%, nws raug cais tawm - tsis txo qis. Vim li cas? Vim hais tias sulfur embrites cobalt alloys raws li ib thaj tsam ntawm grain, ua rau kom qaug zog tawg pib hauv pulsating ib puag ncig. Peb tsis tsuas yog ua tau raws li qhov tshwj xeeb-peb qhia tus cwj pwm ntawm cov khoom siv tiv thaiv cov ntawv thov kev ntxhov siab. Qhov ntawd yog li cas peb xa cov plugs uas muaj sia nyob 12,000+ lub voj voog nyob rau hauv ntug dej hiav txwv roj & roj ntsuas manifolds.
Kev xa tawm tiag tiag hauv ntiaj teb txhais tau hais tias lub sijhawm kwv yees-tsis yog cov lus cog tseg zoo
"Lub Sijhawm Ua Haujlwm" txhais tau tias tsis muaj dab tsi tsis muaj ntsiab lus. Ib qho 12-lub lim tiam tsocai rau 50 stainless hlau twj tso kua mis lub hauv paus assumes raw khoom muaj, rauv teem sij hawm, thiab thawj-kab lus pom zoo cycles-tsis yog hnub ntawv xwb. Peb tsim cov sij hawm nyob ib ncig ntawm lub fwj muaj peev xwm: peb cov kab iav dej khiav rau pwm hauv ib lub lis piam, max. Peb tsis overbook. Hloov chaw, peb ua raws cov qauv tsim nrog kev tsim khoom - yog li koj thawj 5 units siv tau ob qho tib si txheej txheem thiab kev tshuaj xyuas ua ntej ntim ramps. Cov neeg siv khoom hauv North America thiab Europe qhia qhov nruab nrab ntawm kev xa khoom raws sij hawm ntawm 98.3% hauv 18 lub hlis dhau los - tsis yog vim peb maj, tab sis vim peb npaj rov qab los ntawm kev sim ua haujlwm, tsis yog xa mus los ntawm kev txiav txim nkag. Thiab thaum twg ib qho kev hloov tsim hits nruab nrab khiav? Peb rov ua FMEA-tsis yog hloov kho BOM xwb.
Yog koj xav tau ib dej iav casting Hoobkas uas kho koj lub siab valve los yog piston twj tso kua mis vaj tse raws li ib tug system - tsis yog ib feem - koj xav tau pov thawj tswj kev coj cwj pwm alloy, seem seem txuas ntxiv, thiab lub ntiaj teb no validation. Qhov ntawd pib nrog nug tsis yog "Koj puas tuaj yeem pov nws?" tab sis "Yuav ua li cas koj lav nws ua tau?"
