Xav tau cov qauv hlau ua haujlwm-ceev, pheej yig, thiab muaj kev ntseeg siab-tsis tau cog lus rau tag nrho cov cuab yeej tsim khoom? A prototype xuab zeb casting Hoobkas txuas txuas qhov sib txawv. Tab sis tsis yog txhua qhov chaw tsim khoom xa tawm ntawm kev nrawm, raug, lossis cov khoom siv ncaj ncees rau kev khiav qis. Peb tau pom cov neeg siv khoom pov tseg 3-6 lub lis piam - thiab ntau txhiab daus las - tos cov castings uas tuaj txog nrog warpage, porosity, los yog GD&T deviations lawv tsuas ntes tom qab machining. Kev kho tsis tau sai shipping. Nws yog nruj dua kev koom ua ke ntawm casting tsim, pwm ua, thiab nyob rau hauv-txoj kev metrology los ntawm ib hnub.
Yog vim li cas Sand Casting tseem yeej rau thaum ntxov-theem hlau Prototypes
Xuab zeb casting tsis yog cov cuab yeej cuab tam qub-nws yog qhov ua tau zoo tshaj plaws, cov nqi siv tau zoo rau qhov ze-net-zoo li cov hlau hauv qab 100 kg. Tsis zoo li peev casting, nws hla cov qauv siv quav ciab thiab cov plhaub ceramic. Tsis zoo li tuag casting, nws tuav cobalt alloys, stainless hlau, thiab high-silicon hlau yam tsis muaj kev txwv tsis pub siv cov nqi. Ib tus qauv rov siv tau-CNC-machined los ntawm txhuas los yog cob-coated ntoo-txhawb 5 txog 20 tus qauv nchuav. Lub sij hawm xa tuaj poob rau 10-18 hnub. Cov ntaub ntawv yooj yooj yim nyob twj ywm siab: ASTM A48 Chav Kawm 30 grey hlau, ASTM A197 malleable hlau, ASTM A27 LCC carbon steel, thiab txawm AMS 5387 cobalt-nickel superalloy-txhua yam castable nrog tswj solidification thiab tom qab ncuav kub kho.
Tab sis kev ceev txhais tau tias tsis muaj dab tsi yog tias qhov casting distorts thaum lub sij hawm txias los yog ua tsis tiav qhov tseeb ntawm qhov chaw nres tsheb CMM. Qhov ntawd yog qhov uas ntau lub khw "prototype" luv luv. Lawv kho cov xuab zeb casting raws li cov txheej txheem ib leeg-tsis yog thawj qhov ntawm cov saw hlau raug tsim. Peb tau ntsuas txog li 0.8 hli ntawm qhov kev npaj txhij txog ntawm qhov tsis muaj kev tswj xyuas ntsuab-xuab zeb pwm rau lub tog raj kheej lub tog raj kheej. Lub hauv paus ua rau? Tsis sib haum ramming siab, ambient humidity hloov, thiab tsis muaj lub sij hawm ntawm lub sij hawm tseem ceeb hloov xyuas. Txhim kho qhov xav tau kev qhuab qhia hauv pem teb-tsis yog software simulations xwb.
Dab tsi cais qhov tseeb Prototype Sand Casting Factory Los ntawm General Foundry
Kev mob siab rau prototype xuab zeb casting Hoobkas ua hauj lwm nyob rau hauv peb yam tsis-negotiable constraint: traceability, repeatability, thiab responsiveness. Tsis ntim. Tsis yog tus nqi qis tshaj. Nov yog yuav ua li cas nws ua haujlwm hauv kev xyaum:
- Cov ntaub ntawv traceability pib thaum yaj: Txhua batch muaj ntawv pov thawj mill test reports (MTRs), cub cav, thiab spectral tsom xam. Tsis muaj daim ntawv lo "generic alloy". Rau T800 cobalt-based Cheebtsam, peb txheeb xyuas cov ntsiab lus cobalt hauv ± 0.3%, chromium hauv ± 0.2%, thiab carbon tsis pub dhau ± 0.02% - tsis yog ua raws li AMS 5387, tab sis sib xws thoob plaws cov dej.
- Dimensional tswj pib ua ntej pouring: Peb siv optical 3D scanning ntawm txhua tus qauv thiab core box-tsis yog qhov kawg castings. Yog hais tias lub piston twj tso kua mis nyob hauv daim duab hu rau ± 0.15 hli ntawm qhov sib dhos, peb siv tau cov qauv ntawm lub kaum sab xis, cov kab sib cais, thiab qhov chaw luam ntawv tseem ceeb * ua ntej * xuab zeb tau ntim.
- Cov lus teb rov qab kaw hauv cov xuab moos, tsis yog hnub: Thaum tus neeg siv khoom xa GD & T-hnyav lub cev lub cev kos duab, peb pab pawg neeg tsim khoom xa rov qab cov ntaub ntawv kev tsim khoom - suav nrog cov lus pom zoo ntawm cov rooj vag, kev tso chaw riser, thiab kev xav tau cov khoom lag luam xav tau - hauv 48 teev ua haujlwm. Tsis tos rau sab nrauv casting kws pab tswv yim.
Qee tus yuav hais tias xuab zeb casting tsis tuaj yeem tuav nruj nruj. Tab sis peb niaj hnub tuav ± 0.25 hli ntawm cov yam ntxwv tseem ceeb xws li flange bolt voj voog thiab ncej bores - txawm nyob rau ntawm 450 mm-ntev hydraulic valve lub cev - siv cov tshuaj tswj cov xuab zeb, nqus-pab pwm compaction, thiab tom qab-shakeout kev ntxhov siab nyem. Qhov txawv tsis yog khawv koob. Nws tau sau cov txheej txheem cov txheej txheem, cov cuab yeej ntsuas ntsuas, thiab cov kws ua haujlwm uas tau pov 12,000+ qhov chaw lag luam txij li xyoo 2015.
Lub Ntiaj Teb Tshaj Tawm: Yam Koj Tau Txais tiag tiag
Thaum koj koom nrog qhov tseeb qauv xuab zeb casting Hoobkas, koj tsis tau txais raw castings thiab ib daim nqi ntawm lading. Koj tau txais qhov tseeb, npaj txhij-rau-tsim ib feem-nrog cov ntaub ntawv tag nrho. Txhua qhov khoom xa tuaj suav nrog:
- Daim ntawv tshaj tawm kos npe uas qhia CMM- ntsuas qhov tseem ceeb tiv thaiv koj daim duab, nrog rau xim-coded pass / tsis ua raws li txoj cai
- Cov duab ntawm qhov chaw casting - qhia txog qhov me me porosity lossis flash uas poob hauv ASTM A601 cov qauv kev lees paub
- Cov ntaub ntawv kho cua sov (yog tias tau teev tseg), suav nrog lub sijhawm so, qhov ntsuas kub ntawm qhov ntsuas kub, thiab cov ntaub ntawv ntawm lub tshuab cua sov
- Cov ntaub ntawv pov thawj nrog tag nrho cov tshuaj muaj pes tsawg leeg thiab cov txiaj ntsig kev ntsuas kev ntsuas (tensile zog, tawm los, elongation, hardness)
Qhov no tsis yog over-engineering. Nws yog kev pheej hmoo txo qis. Ib lub twj tso kua mis North American OEM zam tau $ 220,000 daim teb rov qab vim tias peb cov khoom xa tawm ua ntej xa hluav taws xob tau ntes tau cov subsurface suav nrog hauv AMS 5387 nozzle-pom tsuas yog nyob rau hauv qhov thib peb ncuav ntawm lawv tsib-ntu qauv batch. Qhov kev soj ntsuam qib ntawd tsuas yog ua haujlwm thaum casting, NDT, thiab kev ntsuas ntsuas nyob hauv ib lub ru tsev.
Cov kauj ruam tom ntej: Yuav Ua Li Cas Pib Koj Tus Qauv Ua Haujlwm Zoo
Pib nrog koj daim duab - tsis yog koj cov peev nyiaj. Xa peb koj STEP lossis IGES cov ntaub ntawv nrog GD&T callouts, cov khoom siv spec, thiab cov kev xav tau ua haujlwm (piv txwv li, "yuav tsum foob ntawm 350 bar yam tsis muaj deformation"). Peb yuav teb nrog cov ncauj lus kom ntxaws DFM, lub sijhawm ua haujlwm, thiab cov lus hais ruaj khov - tsis muaj npe, tsis muaj NDAs yuav tsum tau ua ntej. Peb lub chaw ISO-raws li hauv Qingdao txhawb nqa cov hlau tsis tshua muaj siab ceev los ntawm 2 kg txog 85 kg, nrog rau CNC machining tag nrho, kev kho cua sov, thiab kev ua tiav hauv tsev. Yog tias koj daim ntawv thov xav tau cobalt-nickel alloys, siab-siab ncaj ncees, lossis rov ua microstructure, pib nrog kev qhuab qhia-tsis muaj kev cuam tshuam.
Rau engineers tsim hydraulic systems, roj & roj khoom, los yog engineered tsheb Cheebtsam, txoj cai prototype xuab zeb casting Hoobkas tsis yog ua ib feem. Nws siv tau koj lub hom phiaj tsim-ua ntej koj txiav koj thawj cov cuab yeej tsim khoom.
