Thaum cov engineers qhia meej txog cov khoom siv hydraulic, cov twj siv roj av, lossis cov khoom siv ua haujlwm hnyav, lawv tsis xav tau qhov chaw xwb - lawv xav tau qhov tseeb qhov tseeb nyob rau hauv siab. Tias yog vim li cas muab los ntawm qhov tseeb peev casting khoom Hoobkas teeb meem - tsis yog tus neeg muag khoom, tab sis raws li kev txuas ntxiv ntawm pab pawg tsim. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom ntau lub tsev muag khoom vim tias castings tuaj txog nrog micro-shrinkage nyob rau hauv qhov tseem ceeb sealing zones, los yog vim machined bores drifted 0.015 mm sab nraum GD&T callouts - yuam kev tsis pom ntawm lub qhov muag liab qab tab sis kev puas tsuaj loj hauv kev pabcuam. Peb kho cov qhov khoob ntawm qhov chaw.
Vim li cas "Kev nqis peev Casting Khoom siv Hoobkas" tsis yog ib daim ntawv lo xwb-Nws yog txoj kev cog lus
Ib peev casting khoom Hoobkas yuav tsum tau ua ntau tshaj li nchuav hlau rau hauv cov plhaub ceramic. Nws yuav tsum tswj xyuas qhov sib xws ntawm cov khoom siv hluav taws xob thoob plaws qhov cua sov, khaws cov qauv nplej los ntawm kev kho cua sov, thiab tuav ± 0.02 hli kam rau ua rau cov yam ntxwv zoo li lub rooj zaum lub tog raj kheej lossis lub piston bore runout-tsis muaj kev cia siab rau kev rov ua dua tom qab. Ntawm peb qhov chaw Qingdao, txhua AMS 5387 cobalt alloy nozzle pib nrog cov ntaub ntawv pov thawj T800-qib raw khoom, txheeb xyuas los ntawm kev tshuaj xyuas spectrographic ua ntej yaj. Tsis muaj batch nkag mus rau hauv lub cub tawg yam tsis muaj traceable chemistry cav. Peb tsis outsource core ua los yog plhaub tsev-peb tswj ob qho tib si hauv tsev, vim hais tias lub plhaub thickness variation ncaj qha cuam tshuam rau nto tiav thiab seem drift nyob rau hauv nyias-walled twj tso kua mis vaj tse.
Peb tau ntsuas nws: 5% sib txawv ntawm lub plhaub ziab lub sij hawm nce porosity hauv cobalt-nickel castings los ntawm 22% - txaus ua rau qaug zog ntxov ntxov nyob rau hauv high-cycle applications. Peb lub qhov rais txheej txheem yog nqaim, sau cia, thiab tswj hwm. Qhov ntawd tsis yog over-engineering. Nws yog li cas koj zam kev ua tsis tiav thaum lub ntsaws tsis ua haujlwm ntawm 4,000 psi hauv lub twj tso kua mis tawm sab nraud.
Plaub Muaj Peev Xwm Uas Tshem Tawm Kev Ua Haujlwm - thiab Kev Phem Phem
Cov neeg muag khoom feem ntau cais casting, machining, thiab xov. Qhov ntawd tsim peb cov ntsiab lus sib koom ua ke qhov kev kam rau siab sib xyaw ua ke, kev ncaj ncees ntawm qhov chaw degrades, thiab kev lav phib xaub plooj. Peb integrate tag nrho plaub:
- Casting: Kev nqis peev thiab cov xuab zeb casting kab calibrated rau alloys xws li ductile hlau (ASTM A536) mus rau AMS 5387 cobalt superalloys - tsis muaj generic "high-temp" chaw, tsuas yog cov khoom siv thermal profiles.
- Tshuab dhos: 5-axis CNC chaw nruab nrog kev soj ntsuam cov voj voog uas txheeb xyuas cov ntaub ntawv tseem ceeb * ua ntej * zaum kawg txiav - tshwj xeeb yog qhov tseem ceeb rau asymmetric lub tog raj kheej vaj tsev nyob qhov twg misalignment ruins hydraulic efficiency.
- Kev kho cua sov: Nyob rau hauv-kab lub tshuab nqus tsev vacuum furnaces nrog real-time huab cua xyuas, tsis batch ncu. Peb siv tau cov hardness gradients hla hla ntu ntawm winch center ncej chais-tsis yog cov ntawv nyeem saum npoo.
- Ua tiav: Electropolishing rau stainless hlau twj tso kua mis; HVOF txheej rau cobalt alloy nozzles raug rau abrasive slurry. Qhov saum npoo roughness yog ntsuas - tsis xav.
Qhov kev sib xyaw ntsug no tsis yog hais txog kev txuag nqi ib leeg. Nws yog hais txog kev tshem tawm "lub npov dub" ntawm kev sib tsoo thiab qhov kawg bore geometry. Thaum tus neeg siv khoom xa daim duab kos rau lub siab valve lub cev, peb cov kws ua haujlwm tshuaj xyuas seb qhov kev hloov pauv ntawm phab ntsa puas yuav ua rau muaj kev ntxhov siab ntxiv - thiab kho qhov rooj lossis hloov kho cov txheej txheem machining raws li. Qhov kev pom no tsuas yog los ntawm kev ua ob txoj haujlwm hauv ib lub khw.
Dab tsi engineers tiag nug-Thiab qhov lawv tsis hais nrov nrov
"Koj puas tuaj yeem tuav 0.01 hli ntawm qhov bore?" yog lo lus nug. Qhov tsis hais yog: "Qhov no puas yuav muaj sia nyob 10,000 lub voj voog ntawm 150 ° C yam tsis muaj micro-cracking?" Peb teb ob qho tib si - los ntawm kev sim, tsis cog lus. Txhua lub twj tso kua mis AMS 5387 tau kuaj xyuas ultrasonic * thiab * ntu ntawm cov qauv castings los ntawm txhua qhov cua sov. Peb daim ntawv qhia dendrite caj npab sib nrug. Peb correlates hardness profiles nrog tensile xeem tau. Yog tias tus neeg siv khoom xav tau cov ntaub ntawv rau ASME BPVC Tshooj VIII ua raws, peb xa tag nrho cov ntawv qhia txog cua sov - tsis yog cov ntsiab lus.
Peb tseem chij yam *yuav tsis ua haujlwm. Piv txwv li: T800 alloy resists hnav-tab sis nws cov machinability poob siab tshaj 35 HRC. Yog li yog tias ib daim duab hu rau qhov chaw tawv tawv * thiab * nruj hauv cov xov, peb tawm tswv yim tom qab cua sov kho EDM threading es tsis txhob muaj kev pheej hmoo ntawm cov cuab yeej tawg thiab xov distortion. Qhov kev ntseeg zoo li no txuag lub lis piam - tsis yog hauv khw hauv pem teb xwb, tab sis hauv kev sim ntsuas.
Kev ntseeg tau pib ntev ua ntej thawj lub ncuav
Ib tug txhim khu kev qha peev casting khoom Hoobkas tsis pib ntawm qhov rooj qhov rooj. Nws pib nrog cov khoom siv taug qab mus rau tus lej yaj, txuas ntxiv los ntawm CMM kev kuaj xyuas thawj zaug ntawm cov qauv siv cov neeg siv khoom tshwj xeeb, thiab xaus nrog kev xa mus taug qab uas suav nrog cov ntawv qhia qhov ntev - tsis yog cov npe ntim khoom xwb. Peb ua haujlwm rau North American OEMs uas xav tau PPAP Qib 3 kev xa tawm, Cov neeg muag khoom nyob sab Europe uas kuaj xyuas peb cov txheej txheem ISO 9001: 2015 txhua xyoo, thiab cov neeg tsim khoom hauv tebchaws Esxias sab hnub tuaj uas xav tau lub sijhawm ua haujlwm ruaj khov txawm hais tias tus nqi cobalt hloov pauv.
Peb lub hom phiaj tom ntej? Cov txheej txheem hybrid-zoo li ze-net-puab peev castings uas khaws cia tsuas yog 0.3 hli ntawm Tshuag rau CNC kawg. Tsawg cov khoom pov tseg. Tighter microstructure tswj. Kev xa tawm sai dua. Tsis yog vim nws yog qhov tshiab-tab sis vim tias nws daws qhov teeb meem tiag tiag: tau txais lub luag haujlwm tseem ceeb ntawm txoj cai, raws sijhawm, tsis muaj kev cuam tshuam.
