Thaum cov engineers qhia meej meej cov hlau qhov chaw rau hydraulic li qub, twj tso kua mis vaj tse, los yog winch shafts - qhov chaw uas yuav tsum tuav ± 0.01 hli kam rau ua nyob rau hauv 300-bar siab - lawv tsis tsuas xav tau ib tug neeg muag khoom. Lawv xav tau ib casting thiab hmoov metallurgy Hoobkas uas kho metallurgical sib xws li non-negotiable.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ib qho chaw zoo li no hauv Qingdao - tsis yog lub chaw tsim khoom lag luam lossis lub khw muag khoom, tab sis raws li kev sib koom ua ke ntsug rau lub luag haujlwm tseem ceeb. Peb tau pom cov neeg siv khoom xa rov qab peb zaug nrog kev tsim kho tshiab AMS 5387 cobalt alloy nozzles tom qab ua tsis tiav thermal cycling kev sim lwm qhov. Txhua iteration qhia peb ib yam dab tsi: xuab zeb casting ib leeg yuav tsis stabilize grain qauv hauv T800-raws li twj tso kua mis lub cev; CNC machining ua ntej kev kho cua sov qhia txog kev ntxhov siab seem; thiab qhov chaw tiav tsis yog tshuaj pleev ib ce - nws yog qhov sib txawv ntawm 2,000 teev thiab 8,000 teev ntawm kev pab cuam lub neej hauv roj & roj av nkos twj.
Qhov twg Casting ntsib Precision Machining-tsis muaj kev cuam tshuam
Cov neeg muag khoom feem ntau cais cov casting thiab machining rau hauv cov chaw ua haujlwm - lossis outsource ib qho nkaus. Qhov ntawd ua rau muaj qhov sib txawv ntawm qhov sib txawv: qhov sib txawv ntawm qhov sib txawv ntawm cov khoom pov thawj thiab lub xeev cov tshuab kawg, tsis sib haum xeeb microhardness thoob plaws ntau ntau, los yog GD&T misalignment thaum cov qauv casting tsis suav rau cov cuab yeej nkag mus.
Ntawm peb qhov chaw ISO-raws li, peev casting, xuab zeb casting, thiab ntau-axis CNC machining ua haujlwm nyob rau hauv ib qho system zoo-tsis yog ib lub ru tsev. Peb cam khwb cia hlau vaj tse nrog tswj cov cua txias kom txwv pearlite segregation, ces tshuab lawv ntawm 5-axis chaw nruab nrog in-probing. Rau cov khoom siv cobalt-nickel, peb siv lub tshuab nqus tsev-kev nqis peev casting los tshem tawm cov porosity, ua raws li kev ntxhov siab-nyem annealing * ua ntej * rough machining - yog li qhov kawg contours tuav muaj tseeb thaum txiav tiav.
Qhov kev sib koom ua ke no muab cov txiaj ntsig ntsuas tau: • 92% thawj-dhau tawm los ntawm piston twj tso kua mis lub tog raj kheej vaj tsev (vs. kev lag luam nruab nrab ntawm 68%) • Nto kev ncaj ncees txheeb xyuas los ntawm SEM fractography-tsis yog Ra qhov tseem ceeb • Tag nrho cov traceability los ntawm raw billet daim ntawv pov thawj mus rau qhov kawg CMM daim ntawv qhia, nkag rau AS9102
Vim li cas Cobalt Alloys xav tau ntau dua li "Zoo txaus" txheej txheem
Qee tus yuav sib cav tias cov txheej txheem stainless hlau casting txheej txheem siv sib npaug rau AMS 5387 lossis T800. Lawv tsis ua. Cobalt-based superalloys shrinkable unpredictably thaum lub sij hawm solidification. Lawv thermal conductivity yog ib nrab ntawm 316 stainless. Thiab lawv cov kev ua haujlwm-hardening tus nqi nce tom qab tsuas yog 0.05 hli ntawm kev txiav qhov tob.
Peb kawm qhov no txoj kev nyuaj ntawm qhov tsis yog-tus qauv nruab nrab ncej cov menyuam rau lub tsheb engineering winch. Cov kev sim pib siv cov pa carbide inserts thiab dej nyab lub coolant. Cov cuab yeej lub neej kav ntev li 11 feeb. Cov kab nrib pleb tshwm nyob ntawm qhov tob ntawm 120 µm. Qhov kho? Hloov mus rau PCD-tipped cov cuab yeej, cryogenic nitrogen txias ntawm -196 ° C, thiab machining nyob rau hauv ob lub thermal-ruaj khov theem - ntxhib ntawm ambient, tiav tom qab stabilizing ntawm 20 ° C ± 0.5 ° C rau 4 teev. Qhov tshwm sim: 102-feeb lub cuab yeej lub neej, xoom subsurface puas, thiab qaug zog lub neej txuas ntxiv los ntawm 3.7 ×.
Kev tswj hwm qib ntawd tsuas yog ua haujlwm thaum cov ntaub ntawv tshawb fawb, kos duab physics, thiab machining dynamics nyob hauv tib pab pawg engineering - tsis hla peb email chains.
Kev lees paub tiag tiag hauv ntiaj teb-tsis yog daim ntawv ua raws nkaus xwb
Cov ntawv pov thawj tseem ceeb - tab sis lawv yog daim pib nkag, tsis lav. Peb tuav ISO 9001 thiab AS9100, yog. Tab sis qhov tseem ceeb tshaj yog tias cov qauv no txhais li cas rau hauv koj qhov kev ua tau zoo.
Txhua qhov hlau casting dhau mus kuaj ultrasonic rau ASTM E186, tsis yog kev kuaj pom xwb. Txhua qhov cobalt alloy batch tau txais spectrographic pov thawj tiv thaiv zeb certs - thiab peb khaws cov qauv rau 10 xyoo. Thaum ib tus neeg siv khoom nyob sab Europe xav tau cov ntaub ntawv pov thawj tias lawv lub siab valve lub cev tau ntsib EN 10204 3.2, peb tsis tau xa cov ntaub ntawv. Peb xa cov ntawv pov thawj tiag tiag, kho cua sov nrog rau qhov chaw tsim khoom, nrog cov ntaub ntawv tag nrho tensile, cuam tshuam, thiab hardness.
Peb kuj lees paub kev tsim khoom ua ntej-tsis yog tom qab kev txiav cov cuab yeej. Peb cov engineers chij GD&T tsis sib haum ua ntej hais: "Qhov kev kam rau ua txoj hauj lwm no yuav tsum tau nrhiav nyob rau hauv ib tug cam khwb cia datum uas hloov ± 0.15 hli-cia peb kho lub datum scheme los yog ntxiv ib tug thib ob machining datum." Qhov ntawd txuag lub lis piam - thiab zam cov khoom seem uas muaj nqis txog $ 27,000 txhua.
Yam Koj Yuav Tau Txais—Tshaj Daim Ntawv Qhia
A casting thiab hmoov metallurgy Hoobkas yuav tsum daws cov teeb meem koj tseem tsis tau muaj npe. Nov yog qhov uas txhais tau tias hauv kev xyaum:
- Tsis muaj "black box" quoting: Koj tau txais cov txheej txheem flowcharts, fixture sketches, thiab soj ntsuam cov phiaj xwm nrog txhua RFQ - tsis yog nqi thiab sij hawm ua.
- Tsis muaj qhov xav tsis thoob: Tag nrho cov yam ntxwv tseem ceeb ntsuas ntawm Zeiss CONTURA G2 CMMs, nrog cov ntawv ceeb toom qhia kev sib txawv vectors - tsis yog dhau / tsis ua haujlwm
- Tsis muaj cov khoom tsis meej: Raw Tshuag tau ntawv pov thawj rau AMS 2241, nrog traceability mus rau tus naj npawb cua sov thiab ladle tsom xam
- Tsis muaj kev xa khoom roulette: Lean scheduling txhais tau hais tias tsab ntawv xaj xa tuaj hauv 18 hnub, nruab nrab-ntim khiav ntaus 99.2% raws sij hawm xa tuaj (2023 kev tshawb xyuas sab hauv)
Peb lub hom phiaj tseem nyob qis qis - hydraulic systems, roj & roj khoom, engineering tsheb drivelines, thiab cov twj tso kua mis tshwj xeeb. Peb tsis ua turbine hniav los yog kho mob implants. Qhov kev ua kom pom tseeb ua rau peb cov txheej txheem kev paub: yuav ua li cas cov xuab zeb loj npaum li cas cuam tshuam rau kev sib khi-nto hnav hauv cov khoom siv siab, vim li cas qee qhov kev kho cua sov txhim kho galling tsis kam nyob rau hauv stainless hlau winch shafts, los yog yuav ua li cas tiv thaiv intergranular corrosion nyob rau hauv cobalt alloy plugs raug H₂S.
Yog tias koj qhov project tom ntej no suav nrog kev ua haujlwm nruj-tso rau hauv cov alloys nyuaj-lossis cov khoom sib xyaw uas qhov casting txhais cov geometry thiab machining muab cov chaw ua haujlwm-koj xav tau ntau tshaj qhov muaj peev xwm. Koj xav tau pov thawj tswj qhov tshwm sim ntawm cov hlau molten thiab tiav ib feem. Qhov ntawd yog qhov txhais ntawm qhov tseeb casting thiab hmoov metallurgy Hoobkas.
