Wax casting qhov kev pabcuam muab qhov tsis sib xws ntawm qhov raug rau cov khoom hlau uas ua haujlwm nyob rau hauv qhov hnyav, hnav, lossis thermal stress. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau tsim ntau tshaj 12,000 cov peev txheej-cam khwb cia txij li xyoo 2018-txhua tus tuaj yeem taug qab cov khoom siv raw, kev kho cua sov, thiab daim ntawv tshaj tawm kev tshuaj xyuas CMM zaum kawg. Qhov no tsis yog theoretical muaj peev xwm. Nws yog txhua hnub ua rau hydraulic valve lub cev khiav ntawm 450 bar, cobalt alloy nozzles tuav 650 ° C tso pa roj, thiab twj tso kua mis vaj tse machined rau ± 0.015 hli GD&T callouts.
Yog vim li cas wax casting kev pab cuam tseem ceeb thaum precision yog tsis-negotiable
Kev nqis peev casting pib nrog cov qauv siv quav ciab-tsim rov ua dua qhov kawg ntawm qhov geometry. Cov qauv ntawd tau coated hauv ceramic slurry, dewaxed, thiab raug rho tawm mus rau hauv pwm npaj rau molten hlau. Qhov tshwm sim? Ze-net-puab qhov chaw nrog du nto, nruj tolerances, thiab xoom daim ntawv yuav tsum tau. Tab sis tsis yog txhua qhov kev pabcuam wax casting muab cov txiaj ntsig zoo ib yam. Peb pom nws ntau zaus: cov neeg siv khoom hloov pauv tom qab tau txais castings nrog micro-shrinkage nyob rau hauv ib qho tseem ceeb sealing zones, inconsistent grain qauv thoob plaws AMS 5387 batch, los yog defects nto yuav tsum tau 30% CNC Tshuag tshem tawm ntau tshaj li npaj.
Lub hauv paus ua rau tsis yog ib txwm ua tsis zoo - nws yog qhov tsis zoo ntawm kev tsim qauv, kev coj tus cwj pwm, thiab kev tswj cov txheej txheem. Piv txwv li, T800 cobalt-raws li alloy cog lus 12.4% ntau tshaj 316 stainless thaum lub sij hawm solidification. Ib qho kev pab cuam casting tsis muaj metallurgical tawm tswv yim loops yuav tsim cov qauv uas zoo meej rau CAD tab sis tawm los warped lub tog raj kheej vaj tse tom qab txias. Peb pab neeg siv tau txhua tus qauv tsim tawm tsam cov ntaub ntawv thermal simulation - thiab kho cov rooj vag, nce, thiab lub plhaub tuab ua ntej thawj zaug.
Qhov twg ntsug kev koom ua ke tshem tawm cov ntsiab lus zais zais
Feem ntau cov foundries tso tawm castings mus rau lwm lub tshuab khw. Qhov ntawd ua rau peb cov khaubncaws sab nraud povtseg: qhov sib txawv ntawm qhov casting thiab machining, poob ntawm cov khoom traceability, thiab ncua kev tawm tswv yim ntawm cov qauv tsis xws luag. Peb khiav ob qho tib si peev casting thiab 5-axis CNC machining nyob rau hauv ib tug ISO 9001-certified ru tsev nyob rau hauv Qingdao. Thaum lub piston twj tso kua mis lub tsev tuaj txog ntawm lub cub tawg, nws txav ncaj qha mus rau peb Zeiss Contura G2 CMM - tsis yog mus rau lub logistics chaw nres nkoj. Peb ntsuas raws li-cam khwb cia qhov ntev, muab piv rau cov qauv ua ntej shrinkage, thiab kho cov qauv siv quav ciab tom ntej hauv 48 teev.
- AMS 5387 cobalt alloy qhov chaw tau txais kev daws teeb meem annealing * ua ntej * machining - tsis yog tom qab - kom ruaj khov microstructure thiab tiv thaiv kev cuam tshuam thaum lub sijhawm milling
- Txhua steel casting tau txais tag nrho spectral tsom xam thiab tensile xeem; Cov ntawv ceeb toom suav nrog cov txiaj ntsig tau tiag tiag vs. ASTM A958 spec
- Nto tiav yog tswj qhov kawg-rau-kawg: ceramic plhaub muaj pes tsawg leeg cuam tshuam li-cam khwb cia Ra qhov tseem ceeb, uas txiav txim siab seb peb puas siv tshuaj tua peening lossis electropolish tom qab machining
Qhov no tsis yog yooj yim - nws yog physics-tsav tswj. Lub winch center ncej rau cov menyuam ua los ntawm cov hlau nplaum yuav tsum tuav lub hardness ntawm 285 HB thoob plaws nws lub voj voog. Yog hais tias lub casting txias unevenly, machining qhia cov mos mos. Peb lub qhov cub ntsuas ntsuas kub ntsuas qhov ntsuas kub txhua 90 vib nas this thaum shakeout. Peb sib txuas cov cav nrog hardness maps los ntawm txhua qhov ua tiav. Cov ntaub ntawv no pub rov qab rau hauv cov qauv siv quav ciab hauv pwm.
Kev lees paub tiag tiag-tsis yog kev ua raws cai xwb
Qee tus neeg muag khoom sau npe "ISO tau ntawv pov thawj" thiab "CNC muaj peev xwm" tab sis tsis muaj pov thawj daim ntawv thov kev paub. Peb tsis tsuas yog ua tau raws li cov qauv-peb sim tiv thaiv cov hom kev ua tsis tiav. Peb cobalt alloy plugs underwed 14,000 cycles nyob rau hauv ib tug simulated roj & roj downhole ib puag ncig ua ntej tso. Lub siab li qub tau sim hydrostatically rau 1.5 × rated siab, tom qab ntawd tshuaj xyuas ntawm dye penetrant thiab kuaj ultrasonic rau subsurface discontinuities. Cov no tsis yog xaiv add-ons. Lawv tau tsim rau hauv peb cov kev pabcuam kev ua haujlwm ua haujlwm vim tias cov neeg siv khoom xa cov khoom no mus rau hauv cov txheej txheem kev nyab xeeb.
Peb kuj tseem chij yam * tsis tuaj yeem * raug pov tseg - ntxov. Ib tus neeg siv khoom ib zaug xa ib daim duab rau ib lub phab ntsa nyias nyias (2.3 hli) stainless hlau manifold nrog cov kab hauv qhov hla-drilled. Peb cov engineers tau khiav dej-simulation ntawm tus qauv siv quav ciab thiab txheeb xyuas cov hlau turbulent uas yuav ua rau txias kaw. Es tsis txhob hais qhov muag tsis pom kev, peb tau npaj ib txoj hauv kev hybrid: peev-cam khwb cia lub ntsiab, tom qab ntawd CNC-tshuab cov yam ntxwv sab hauv. Qhov ntawd tau txais kev cawmdim 37% ntawm tag nrho cov nqi piv rau kev sim yuam cov geometry los ntawm casting ib leeg.
Xaiv koj tus neeg siv khoom siv quav ciab casting
Nug peb lo lus nug ua ntej cog lus:
- Lawv puas tuaj yeem qhia koj CMM cov ntawv ceeb toom rau ntau qhov tsis ntev los no ntawm koj cov qib pes tsawg-tsis yog cov qauv?
- Lawv puas ua cov ntaub ntawv pov thawj * thiab * khaws daim coupon ntawm lub cev los ntawm txhua qhov cua sov rau kev rov kuaj dua?
- Thaum qhov loj me poob rau sab nraud, lawv puas rov qab qhov tsis xws luag nrog cov duab piav qhia thiab kev txheeb xyuas hauv paus-los yog tsuas yog muab qhov hloov pauv?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho peb. Peb sau txhua kauj ruam tshuaj xyuas, khaws tag nrho cov ntaub ntawv ntsuas ntsuas, thiab qhia tag nrho cov ntaub ntawv tshawb xyuas nrog cov neeg siv khoom. Peb qhov kev pabcuam siv quav ciab txhawb nqa tus qauv ua haujlwm me me li 5 daim thiab cov khoom ntim ntau txog 5,000 units ib xyoos ib zaug - tsis hloov cov cuab yeej lossis cov txheej txheem. Vim tias kev sib haum xeeb tsis yog lub hom phiaj. Nws yog lub hauv paus.
Yog tias koj qhov project tom ntej no xav kom muaj kev ncaj ncees nyob rau hauv kev kub ntxhov, kev tiv thaiv corrosion hauv kev tawm tsam hnyav, lossis lub neej qaug zog tshaj li 10⁷ cycles - pib nrog kev pabcuam wax casting uas kho metallurgy li engineering, tsis yog artistry. Precision pib qhov twg cov wax melts.
