Thaum engineers xav tau precision hlau qhov chaw uas muaj sia nyob 30,000 psi hydraulic cycles los yog 650 ° C tso pa tawm, lawv tsis pib nrog ib tug generic foundry. Lawv pib nrog a poob ciab casting kev pab cuam Hoobkas uas kho cov cobalt alloy nozzles zoo li cov cuab yeej phais - thiab paub meej tias AMS 5387 cov qauv nplej teb li cas rau thermal shock thaum dewaxing.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yog ib lub Hoobkas zoo li no. Tsis yog tus broker. Tsis yog ib lub tuam txhab lag luam. Kev ua haujlwm ntawm tes, ISO-raws li kev ua haujlwm hauv Qingdao qhov chaw metallurgists kho slurry viscosity raws li cov av noo nyob ib puag ncig-thiab cov tshuab ua haujlwm rov xoom tsib-axis spindles ua ntej txiav T800 cobalt-based shafts rau offshore winch systems. Peb tau pom cov neeg siv khoom poob peb lub lis piam thiab $ 18,000 hauv kev rov ua haujlwm vim tias lawv tus neeg xa khoom ua ntej hla kev pov npav ua ntej GD&T validation. Ntawm qhov chaw no, qhov kev pheej hmoo loj yuav raug ntes ua ntej thawj cov qauv siv quav ciab solidifies.
Lawv txoj kev ploj ploj tsis yog "kev nqis peev casting." Nws yog lub kaw lus nruj nruj: cov ntaub ntawv pov thawj raw khoom traceability → ceramic plhaub formulation tuned rau high-alloy thermal expansion → tswj dewaxing ramp tus nqi → nqus-pab pouring ntawm superalloys ntawm ± 5 ° C kam rau ua → post-cast stress nyem calibrated rau AMS 2750E pyromet qauv. Rau lub siab li qub lossis piston twj tso kua mis lub tog raj kheej vaj tse, uas txhais tau hais tias phab ntsa thickness variation nyob qis dua ± 0.15 hli - txawm nyob rau ntawm 420 hli OD castings nrog cov cua txias sab hauv. Tsis muaj kwv yees. Tsis muaj batch-rau-batch drift. Txhua lub tshav kub muaj cov ntaub ntawv qhia txog spectrographic thiab daim ntawv pov thawj tensile.
Dab tsi cais lawv los ntawm cov qauv tsim? Peb qhov kev ua haujlwm tiag tiag:
- Alloy kev qhuab qhia - tsis yog muaj peev xwm xwb. Lawv tsis "kuav" cobalt-nickel alloys. Lawv ua haujlwm rau cov chaw taws teeb tshwj xeeb rau AMS 5387, nrog rau cov crucibles, ladles, thiab slag-k tuav cov txheej txheem los tiv thaiv kev sib kis nrog cov qib stainless. Thaum tus neeg siv khoom xa tuaj rau hauv daim duab kos rau qhov tsis yog-tus qauv cobalt alloy ntsaws nrog 0.05 hli txoj hauj lwm kam rau ua rau rau qhov chaw nres nkoj, pab pawg tsis tau hais qhov muag tsis pom. Lawv tau khiav kev sib sau ua ke ntawm cov quav ciab, txheeb xyuas qhov chaw tso ntawm qhov chaw simulation, thiab paub tseeb tias lub plhaub hlawv lub sij hawm-ua ntej pom zoo PO.
- Tsis muaj kev sib koom tes ntawm casting thiab machining. Feem ntau cov neeg xa khoom tawm ntawm CNC ua haujlwm tom qab casting. Ntawm no, tus engineer zoo tib yam kos npe tawm ntawm ob qho tib si li-cam khwb cia nto tiav (Ra ≤ 3.2 μm) thiab qhov kawg machined datum (CMM-tsim pov thawj rau ± 0.01 hli). Qhov ntawd tshem tawm cov teeb meem kev teeb tsa thaum tig lub twj tso kua mis lub hauv paus mounting flange thiab tho rau hauv ib qho kev teeb tsa - qhov tseem ceeb rau hydraulic foob kev ncaj ncees.
- Failure-mode awareness ua rau txhua kauj ruam. Rau cov hlau thiab stainless hlau castings siv hauv cov khoom siv roj thiab roj, lawv ua cov tshuaj ntsuam xyuas cov dej nkag * tom qab * tua blasting tab sis * ua ntej * machining - ntes micro-shrinkage porosity uas sib tsoo yuav txwv tsis pub lub npog ntsej muag. Yog hais tias T800 alloy ib feem qhia subsurface oxide inclusions nyob rau hauv ultrasonic scan, nws yog scrapped - tsis "reworked." Vim hais tias nyob rau hauv lub hom phiaj tseem ceeb daim ntawv thov, "zoo txaus" ua tsis ntsiag to - thiab kev puas tsuaj loj.
Qee tus yuav sib cav hais tias xuab zeb casting muaj kev hloov pauv sai rau cov hlau loj loj. Tab sis thaum ib feem yog winch center ncej cov menyuam ua haujlwm nyob rau hauv cyclic torsional load, geometry fidelity tseem ceeb tshaj qhov ceev. Poob ciab muab cov duab ze-net nrog cov phab ntsa tsis muaj cua ntsawj ntshab, tshem tawm cov machining theem nrab ntawm cov kabmob tseem ceeb. Thiab yog - nws raug nqi ntau dua ua ntej. Tab sis ib tus neeg siv tau txo tag nrho tus nqi ntawm ib lub valve los ntawm 22% tom qab hloov pauv: tsawg dua cov rooj sib tham tsis lees paub, xoom teb xau, thiab txuas ntxiv kev pab cuam lub neej los ntawm 14 lub hlis mus rau 36+ lub hlis hauv thaj chaw suab puam-xuab zeb.
Qhov no tsis yog theoretical. Nws yog rov ua tau. Lawv cov khoom siv hauv pem teb ua haujlwm lean workflow-tsis yog raws li cov lus hais, tab sis raws li kev xyaum txhua hnub. Prototypes nkoj hauv 12 hnub ua haujlwm. Kev txiav txim nruab nrab-ntev (50-500 pcs) tuav ± 3-hnub xa khoom qhov rais - lav hauv kev sau ntawv. Kev tswj hwm qhov project suav nrog lub sijhawm kos duab kos duab, GD&T teeb meem daws teeb meem, thiab kev tawm tswv yim tsim khoom hauv 48 teev ntawm RFQ xa. Tsis muaj black-box quoting. Tsis yog "peb yuav pom nws tom qab." Tsuas yog engineering alignment los ntawm ib hnub.
Saib tom ntej, qhov ua kom pom tseeb: tob R & D rau hauv hybrid casting-machining sequences rau ultra-thin-walled twj tso kua mis vaj tse, nthuav daim ntawv pov thawj rau aerospace-qib cov ntaub ntawv pom zoo, thiab nruj kev koom ua ke ntawm cov txheej txheem thermal imaging thaum lub plhaub firing. Tab sis lub hauv paus tseem tsis hloov pauv - lawv lub ntsiab lus ntawm qhov tseeb poob ciab casting kev pab cuam Hoobkas tsis yog hais txog cov khoom siv tshwj xeeb. Nws yog hais txog tus kheej lub txim ntawm txhua micrometer, txhua qhov suav nrog, txhua lub voj voog kub. Vim tias thaum koj cov khoom tuav rov qab 5,000 nkas loos dej hiav txwv - lossis tswj cov roj ntws hauv lub tshuab hluav taws xob - lub Hoobkas koj xaiv tsis muab hlau. Nws muab kev ntseeg siab.
