Thaum koj hnov 'precision casting rau cov cuab yeej kho mob', cov duab tam sim no feem ntau tsis muaj qhov tsis zoo, cov khoom tsis muaj menyuam tawm los ntawm cov kab ntau lawm. Qhov ntawd yog kev lag luam gloss. Qhov tseeb, los ntawm qhov uas kuv tau sawv rau xyoo, yog ib qho kev seev cev zoo nkauj ntawm metallurgy, geometry, thiab qhov kev thov tsis zam txim ntawm tib neeg lub cev. Ib qho kev xav tsis zoo yog tias nws tsuas yog ua cov khoom me me thiab ci ntsa iab. Tsis yog. Nws yog hais txog kev ua tau zoo nyob rau hauv ib puag ncig uas tsis ua haujlwm tsis yog qhov kev xaiv, thiab qhov kev xaiv ntawm, hais tias, cobalt-chromium alloy thiab qib tshwj xeeb ntawm kev phais stainless hlau tuaj yeem hinge ntawm lub cev qaug zog uas tsuas pom nws tus kheej tom qab lub hlis ntawm kev sim. Cia peb tham txog dab tsi tiag tiag zoo li ntawm lub khw hauv pem teb.
Cov khoom yog Cov Lus
Koj pib nrog lub alloy. Ib txwm. Kev xaiv cov khoom siv rau kev phais lossis kev cog hniav tsis zoo li xaiv cov khoom lag luam rau lub bracket. Muaj biocompatibility, paub meej, tab sis qhov ntawd tsuas yog daim pib mus rau qhov kev ua si. Txoj haujlwm tiag tiag yog nyob rau hauv qhov nws coj thaum lub sijhawm thiab tom qab precision casting. Siv 316LVM stainless. Zoo corrosion kuj, dav siv. Tab sis nws cov yam ntxwv ntws thaum lub sij hawm peev casting txawv ntawm, hais, ib tug cobalt-raws li alloy zoo li CoCrMo. Cov tom kawg muaj qhov siab dua melting point thiab txawv shrinkage cwj pwm. Yog tias koj khiav tib lub plhaub pwm thiab nchuav qhov tsis sib xws rau ob qho tib si, koj tab tom thov kom muaj teeb meem - sab hauv porosity hauv ib qho, kua muag kub hauv lwm qhov. Kuv tau pom tej yaam num stumble nyob ntawm no, piv txwv li ib-loj-fits-tag nrho cov txheej txheem.
Qhov no yog qhov uas qhov kev paub ntev ntawm cov ntaub ntawv tseem ceeb. Ib lub khw uas tuav ntau txhiab cua sov ntawm cov khoom kho mob qib sib txawv tsim ib hom kev paub tsis meej. Lawv paub tias ib qho tshwj xeeb nickel-raws li alloy tej zaum yuav ua rau micro-shrinkage ntawm tej phab ntsa-thickness hloov, ib yam dab tsi tus qauv simulation yuav plam. Nws tsis yog hais txog kev muaj ntawv pov thawj; nws yog hais txog muaj lub cim xeeb nyob rau hauv lub foundry. Tuam txhab uas muag tau nyob rau hauv lub tuab ntawm nws, zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb lub xyoo caum hauv casting thiab machining, tau tso cov ntaub ntawv no los ntawm kev siv thev naus laus zis. Cov keeb kwm ntawd txhais ncaj qha rau hauv tsawg dua thawj cov ntawv ua tsis tiav.
Kev kho cua sov tom qab casting yog lwm qhov minefield. Kev ntxhov siab, kev daws teeb meem, kev laus - nws yog ib qho tseem ceeb rau kev ua tiav cov khoom siv kho tshuab kawg. Tau txais lub voj voog tsis raug, thiab koj tuaj yeem embrittle ib feem lossis ua kom nws cov corrosion kuj. Kuv nco qab txog ib rooj plaub uas muaj kev puas tsuaj uas qhov kev laus dhau mus ua rau muaj kev qaug zog ntxov ntxov hauv kev sim simulated. Tus neeg ua txhaum? Ib qho kev xav tias daim ntawv qhia rau cov hlau zoo sib xws yuav ua haujlwm. Nws coj kev tshuaj xyuas kev sib koom ua ke nrog tus kws tshuaj metallurgist thiab ib kauj ruam rov qab mus rau alloy spec's isothermal transformation diagram los kho nws.
Lub Plhaub Game: Ntau dua li Pwm
Kev nqis peev casting, lossis plhaub pwm casting, yog lub plawv ntawm qhov no. Cov txheej txheem siv quav ciab yog qhov muag heev, tab sis lub plhaub tsev yog qhov chaw kos duab raws li kev tshawb fawb. Txhua slurry dip, txhua daim ntawv thov cov xuab zeb stucco, tsim ib lub plhaub ceramic uas yuav tsum tiv taus lub thermal poob siab ntawm cov hlau molten thaum tuav qhov kev ntseeg siab. Lub thickness tsis sib xws; koj tuaj yeem tsim nws tuab nyob ib ncig ntawm cov ntu loj los tswj cov cua txias. Kuv tau siv sij hawm nrog cov txheej txheem engineers debating lub viscosity ntawm thawj slurry lub tsho tiv no - nyias nyias, thiab koj tau txais tsis zoo nto tiav; tuab heev, thiab koj yuav raug cua los yog ua rau lub plhaub tawg thaum dewaxing.
Dewaxing nws tus kheej yog ib kauj ruam ua nruj ua tsiv. Koj sai sai yaj los yog steaming tawm cov quav ciab los ntawm sab hauv lub plhaub tsis yooj yim. Ua tsis ncaj ncees lawm, thiab lub plhaub tawg los ntawm kev ntxhov siab thermal, ua rau nws tsis muaj txiaj ntsig. Niaj hnub no autoclaves pab, tab sis koj tseem yuav tsum tau hu rau hauv lub siab thiab kub ramp tus nqi rau qhov tshwj xeeb wax blend thiab plhaub thickness. Nws yog ib kauj ruam uas zoo nkaus li zoo li kev tswj tawg ntau dua li kev tsim khoom.
Lub plhaub kawg, tom qab kub kub tua hluav taws, yog qhov no tsis txaus ntseeg, ntxeem tau, tsis tau muaj zog. Muab cov hlau tso rau hauv nws yog lub sijhawm ntawm qhov tseeb. Lub rooj vag system tsim-feem ntau saib tsis tau los ntawm cov neeg tsim qauv tsom rau ntawm ib sab-yog qhov tseem ceeb. Nws tsis yog ib qho channel rau hlau xwb; nws yog ib qho kev tswj xyuas thermal thiab pub mis. Lub rooj vag tsim tsis zoo tuaj yeem ua rau muaj kev kub ntxhov (ua rau muaj kev sib koom ua ke) lossis ua tsis tau cov khoom ntim rau hauv qhov kawg kom khov. Peb ib zaug muaj ib tug complex orthopedic Cheebtsam uas ua rau kom pom shrinkage porosity nyob rau hauv ib tug zais sab hauv ces kaum. Kev tsim kho lub rooj vag thiab ntxiv cov tswv yim riser daws tau nws, tab sis nws yuav tsum tau txiav ntau ntau cov castings los kuaj xyuas.
Precision yog Txoj Kev, Tsis yog Snapshot
Tolerances nyob rau hauv cov cuab yeej kho mob casting yog nruj, feem ntau nyob rau hauv microns rau cov yam ntxwv tseem ceeb. Tab sis raws li-cam khwb cia kam rau ua yog ib qho lus dab neeg. Txhua qhov casting yuav muaj qee qhov sib txawv. Qhov kev txawj ntse tiag tiag yog tswj hwm qhov sib txawv ntawm qhov sib txawv thiab paub txog dab tsi yuav raug ntxuav hauv CNC machining tom ntej. Qhov no yog vim li cas kev koom ua ke cov chaw ua ke uas ua ke casting thiab CNC machining nyob rau hauv ib lub ru tsev, zoo li QSY kev teeb tsa, muaj qhov zoo sib xws. Cov machinists thiab foundry engineers tuaj yeem tham. Lawv tuaj yeem txiav txim siab, piv txwv li, tawm ntawm ib nrab-millimeter ntawm cov khoom lag luam ntawm qhov nyuaj-rau-cam khwb cia vim tias nws yooj yim dua thiab txhim khu kev qha rau tshuab nws mus rau qhov kawg loj dua li mus caum lub ntsej muag zoo meej.
Thawj tsab xov xwm tshuaj xyuas yog cov ntaub ntawv tseem ceeb tshaj plaws. Nws tsis yog daim ntawv hla dhau / poob. Nws yog daim ntawv qhia txog kev muaj peev xwm. Koj tab tom nrhiav rau cov qauv hauv qhov sib txawv. Puas yog tag nrho qhov ntev ntawm ib sab ntawm nominal? Qhov ntawd yuav qhia tau tias muaj kev hloov pwm zoo ib yam. Puas yog qhov chaw roughness siab dua ntawm qhov chaw sab saud? Qhov ntawd tuaj yeem yog qhov teeb meem slag lossis oxide suav nrog. Cov ntaub ntawv no pub rov qab ncaj qha rau hauv kev kho cov txheej txheem. Nws yog qhov rov ua dua, qee zaum ntxhov siab li ntawd.
Thiab tom qab ntawd muaj kev tu. Tom qab shakeout, koj muaj ib feem fused nrog ceramic rooj vag thiab ib tug ntxhib nto. Qhov deburring, tshem tawm ceramic (feem ntau nrog blasting hnyav los yog tshuaj leaching), thiab passivation rau stainless qhov chaw yog qhov ntau qhov chaw defects yog qhia yog tsis ua tib zoo tswj. Ib qho kev tawm tsam hnyav heev tuaj yeem ua haujlwm hnyav thiab smear rau saum npoo, npog qhov porosity uas tom qab dhau los ua qhov pib tawg. Nws yog ib kauj ruam uas yuav tsum tau ntau npaum li finesse li lub pouring.
Thaum Nws Mus Tsis Zoo: Lub Sijhawm Kawm
Kev ua tsis tiav yog cov kws qhia zoo tshaj plaws, yog tias koj raug tso cai qhib rau lawv. Ib qhov project thaum ntxov muaj kev cuam tshuam nrog laparoscopic txiab, ib qho me me, intricate ib feem. Cov prototypes saib zoo meej, dhau kev tshuaj xyuas thawj zaug. Tab sis thaum lub sij hawm ua hauj lwm lub neej xeem, lub pivot qhov elongated, ua si. Kev soj ntsuam tsis ua hauj lwm taw qhia tsis yog qhov tsis xws luag, tab sis rau cov khoom siv lub zog tawm los. Peb tau teev tus qauv 17-4PH, tab sis rau qhov tshwj xeeb geometry thiab kev thauj khoom, nws xav tau kev kho cua sov sib txawv kom ua tiav qhov nyuaj dua. Cov precision casting yog flawless, tab sis cov khoom specification rau daim ntawv thov yog tsis ncaj ncees lawm. Nws yog ib qho kev ua phem rau hauv kev xav.
Lwm lub sij hawm, peb ntsib qhov tsis sib xws ntawm phab ntsa tuab hauv cov phab ntsa nyias nyias. Kev txhaj tshuaj wax tau zoo, lub plhaub zoo li zoo. Qhov teeb meem tau taug qab rov qab mus rau wax pattern assembly ntoo. Lub kaum sab xis ntawm qhov tshwj xeeb no tau txuas rau hauv nruab nrab sprue tau ua rau lub plhaub tsis sib xws thaum lub sij hawm dipping, ua rau lub tsho me ntsis thinner ceramic rau ntawm ib sab, uas txhais ua cov phab ntsa hlau tuab. Ib qho kev hloov me ntsis ntawm ib feem ntawm tsob ntoo kho nws. Cov no yog hom feeb, cov txheej txheem tsis pom tseeb ntawm kev sib cuam tshuam koj tsuas yog kawm los ntawm kev siv tes ua, rov ua dua.
Cov kev paub dhau los no qhia meej tias vim li cas kev koom tes nrog cov chaw tsim khoom raws caij nyoog tsis yog hais txog outsourcing ib daim duab. Nws yog hais txog tapping rau hauv lub reservoir ntawm cov tswv yim daws teeb meem. Lub tuam txhab lub neej ntev, zoo li QSY txoj haujlwm 30 xyoo, feem ntau txhais tau hais tias lawv tau ntsib thiab daws cov teeb meem tsis pom tseeb ua ntej, txuag koj lub sijhawm thiab tus nqi ntawm kev rov tshawb nrhiav lawv.
Lub neej yav tom ntej tsis yog Additive xwb
Muaj ntau lub suab nrov ntawm 3D luam ntawv rau cov khoom siv kho mob, thiab yog vim li cas. Tab sis rau nruab nrab-rau-siab ntim ntau lawm ntawm me me, complex, hlau Cheebtsam, peev casting tseem nyuaj heev los yeej ntawm tus nqi-kev ua tau zoo. Qhov saum npoo tiav, metallurgical kev ncaj ncees, thiab txhua yam khoom los ntawm cov txheej txheem casting zoo tseem zoo dua rau ntau qhov kev cog khoom thiab cov cuab yeej siv. Lub neej yav tom ntej, kuv xav tias, yog nyob rau hauv hybridization. Siv 3D luam ntawv los tsim cov qauv siv tsis yooj yim los yog txawm tias ncaj qha ceramic shells rau prototyping lossis ultra-complex one-offs, ces leveraging tsim, scalable, thiab nqi-zoo precision casting txheej txheem rau ntau lawm.
Cov xov digital kuj tseem nruj. Simulation software rau pwm filling thiab solidification tau zoo dua, tab sis nws tseem yog ib qho kev qhia, tsis yog oracle. Qhov kev siv tau zoo tshaj plaws uas kuv tau pom yog muab piv rau qhov kev kwv yees simulation nrog qhov tseeb thawj-kab lus cov ntaub ntawv thiab cov ntawv qhia porosity los ntawm kev tshuaj xyuas X-ray. Calibrating tus qauv rau koj lub khw hauv pem teb tej yam kev mob - koj alloy yaj, koj lub plhaub khoom - uas yog qhov twg tus nqi tiag tiag. Nws txo cov iteration cycles.
Yog li ntawd, qhov twg yuav tso peb? Precision casting rau cov khoom siv kho mob yog cov cuab yeej paub tab, tab sis nws nyob deb ntawm qhov zoo li qub. Nws yog ib qho khoom siv sib sib zog nqus, uas tau tsav los ntawm cov ntsiab lus thiab kev kawm empirical. Lub hom phiaj tsis yog qhov zoo tshaj plaws casting txhua lub sijhawm - uas yog tsis yooj yim sua. Lub hom phiaj yog txheej txheem kev kwv yees uas koj nkag siab txog hom kev ua tsis tiav, tswj hwm qhov tsis tseem ceeb, thiab muaj kev txawj ntse los kuaj xyuas thiab hloov kho. Qhov ntawd yog qhov cais ib feem uas zoo nkaus li zoo ntawm daim ntawv spec los ntawm ib qho uas ua tau zoo hauv ib tus neeg.
