Thaum cov engineers qhia ib feem uas yuav tsum tuav ± 0.01 hli kam rau ua nyob rau hauv 350-bar hydraulic siab - thiab muaj sia nyob 10,000+ cycles nyob rau hauv abrasive slurry - lawv tsis tsuas yog xav tau ib tug foundry. Lawv xav tau ib IMPRO peev casting Hoobkas uas kho metallurgy zoo li code thiab seem stability zoo li daim ntawv cog lus txoj cai.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ib qho chaw hauv Qingdao - tsis yog lub khw muag khoom hlau, tab sis raws li tus khub precision rau lub luag haujlwm tseem ceeb hauv qhov tsis ua haujlwm tsis raug nqi - nws yog kev puas tsuaj. Peb tau pom cov neeg siv khoom xa rov qab peb zaug nrog tib AMS 5387 cobalt alloy twj tso kua mis vaj tsev teeb duab: thawj zaug rau cov khoom siv porosity ntawm lub rooj zaum valve, thib ob rau microcracking tom qab kev kho cua sov, qhov thib peb vim qhov ua tiav tsis tau raws li cov qauv ntsuas ntsuas. Txhua zaus, lub hauv paus ua rau tsis yog "casting quality" - nws yog misalignment ntawm alloy cwj pwm, gating design, thiab post-cast stress relief sequencing. Qhov ntawd yog qhov chaw no lub Hoobkas xa khoom.
Vim li cas cobalt-nickel alloys xav tau ntau dua li "kev nqis peev casting"
Feem ntau cov neeg muag khoom kho AMS 5387 lossis T800 tsuas yog lwm qib ntawm daim ntawv qhia tshwj xeeb. Hauv kev muaj tiag, cov hlau no txo qis 17% ntau dua 316 stainless hlau thaum lub sij hawm khov kho, txhim kho thermal gradients 3 × steeper nyob rau hauv nyias-walled seem, thiab tiv thaiv machining aggressively tias cov cuab yeej carbide hnav 40% sai dua yog tias kev kho cua sov ua ntej tsis yog lub sijhawm. Peb tau ntsuas qhov no - ntawm qhov tseeb piston twj tso kua mis lub tog raj kheej vaj tse tsim rau cov roj av sab nrauv & kev pabcuam roj.
QINGDAO QIANGSENYUAN tsis outsource alloy tsim nyog. Lawv pab pawg kws tshaj lij ua haujlwm sib koom ua ke cov khoom siv raw khoom nrog cov neeg muab ntawv pov thawj - taug qab cov khoom lag luam loj, kev cuam tshuam ntawm theem intermetallic, thiab cov ntsiab lus oxygen mus txog 15 ppm. Thaum tus neeg siv khoom xa T800 nozzle nrog kev yaig ntxov ntxov ntawm lub caj pas, peb taug qab nws rov qab rau qhov tsis sib xws niobium carbide nag lossis daus hauv ib lub tshav kub. Qhov kho? Kho cov tshuaj anneal ramp tus nqi los ntawm 0.8 ° C / sec - thiab tuav cov ntaub ntawv rau txhua kilogram cam khwb cia.
Qhov kev tswj hwm no tsuas yog ua haujlwm vim lawv IMPRO peev casting Hoobkas integrates txheej txheem cov kauj ruam lwm yam silo: wax qauv geometry yog validated tiv thaiv CNC toolpaths * ua ntej * plhaub tsev; Thaum tshav kub kub kho cycles yog synchronized nrog zaum kawg machining fixtures; Qhov kev ua tiav ntawm qhov kawg (Ra ≤ 0.4 μm) raug txheeb xyuas siv cov khoom siv kho qhov muag - tsis yog tactile probes - vim tias cov dej ntws tawm xav tau sub-micron repeatability.
Vertical kev koom ua ke tsis yog buzzword - nws yog kev kam rau siab stacking pov hwm
Qee cov neeg muag khoom hais tias casting-tsuas, ces subcontract machining rau peb lub khw sib txawv. Uas qhia txog qhov yuam kev: casting shrinkage + machining fixture hloov + thermal distortion = qhov chaw uas haum rau CMM tab sis khi hauv kev sib dhos. Ntawm QINGDAO QIANGSENYUAN, tib pab pawg engineering muaj cov saw hlau tag nrho-los ntawm GD&T kev txhais lus ntawm kev tshuaj xyuas kos duab hu mus rau qhov kawg ua haujlwm ntawm lub rooj zaum hydrostatic.
Peb tau taug qab 42 lub siab valve lub cev hla ob qhov kev tsim khoom. Cov tshuab tag nrho hauv tsev tau pom 92% qhov rov ua dua ntawm qhov chaw sib khi tseem ceeb. Cov neeg uas muaj kev ua tiav tiav tau poob mus rau 68%. Qhov txawv? Fixture-rau-fixture datum hloov qhov yuam kev qhov nruab nrab ntawm 0.018 hli - txaus los cuam tshuam npuas-nruj kaw ntawm 250 bar.
- CNC machining: 5-axis ib txhij contouring rau txoj hauv kev hauv cov twj tso kua mis
- Kev kho cua sov: Nqus annealing nrog real-time thermocouple daim ntawv qhia hauv txhua qhov load
- Tiav: Electropolishing rau corrosion kuj * thiab * micro-smoothness - txheeb xyuas los ntawm SEM imaging
Tsis muaj cov kauj ruam raug xa tawm yam tsis muaj ntaub ntawv pov thawj: ntau tus lej, tus neeg teb xov tooj ID, cov cav ntsuas tshuab, thiab CMM cov ntaub ntawv khaws tseg rau AS9102 tus qauv - txawm tias tsis yog aerospace xaj. Vim hais tias thaum lub winch center ncej cov menyuam ua tsis tau ib nrab-nqa ntawm lub mining excavator, "peb ua raws li txheej txheem" tsis txaus. Koj xav tau cov ntaub ntawv pov thawj ntawm * dab tsi * txheej txheem - thiab raws nraim li cas nws ua.
Kev xa tawm tiag tiag hauv ntiaj teb txhais tau hais tias kev ua haujlwm ua haujlwm - tsis yog hnub tim xwb
"Kev xa khoom raws sij hawm" txhais tau tias tsis muaj dab tsi yog tias thawj cov khoom xa tuaj tuaj nrog cov xov tsis raug ntawm cov hlua cobalt alloy. QINGDAO QIANGSENYUAN tsim lub sij hawm resilience rau engineering-tsis yog logistics. Lawv cov thawj tswj haujlwm tsis yog taug qab lub sijhawm ua haujlwm xwb; lawv chij manufacturability txaus ntshai * ua ntej * tooling pib.
Xyoo tas los, cov neeg siv khoom nyob sab Europe tau xa ib qho kev hloov kho GD&T rau hydraulic manifold block. Peb pab neeg pom tau hais tias txoj hauj lwm kam rau ua (± 0.025 hli) ntawm datum C yuav xav tau kev sib tsoo tom qab casting - ntxiv $ 1,200 / unit thiab 3 lub lis piam ncua. Hloov chaw, lawv tau thov hloov kho cov ntawv luam tawm los hloov cov ntaub ntawv mus rau qhov chaw ua haujlwm, ua tiav qhov kev ua haujlwm zoo ib yam ntawm 40% tus nqi qis. Cov neeg tau txais kev pom zoo hauv 48 teev.
Qhov no tshwm sim vim lawv cov engineers hais ob qho tib si foundry thiab fluid dynamics. Lawv paub tias yog vim li cas 0.1 hli offset nyob rau hauv lub nozzle lub tso tawm lub kaum sab xis hloov cov qauv kev ua tau zoo los ntawm 11%. Lawv tau sim cov dej coefficients ntawm 17 cobalt alloy geometries - tsis yog los ntawm simulation ib leeg, tab sis nrog calibrated flow benches khiav dej ua hauj lwm.
Yog tias koj tab tom nrhiav cov khoom siv hlau zoo uas qhov kev ua tau zoo ntawm kev ua haujlwm ntawm microstructure, tsis yog qhov loj me xwb, qhov kev xaiv tsis yog ntawm cov neeg muag khoom - nws yog ntawm qhov kev xav thiab cov pov thawj. Ib IMPRO peev casting Hoobkas tsis cog lus tias yuav zoo tag nrho. Nws muab traceable, repeatable, functionally validated results-ib qho tseem ceeb ntawm ib lub sij hawm.
