Cia peb ua siab ncaj, thaum cov neeg feem coob hnov qhov siab precision casting, lawv daim duab tsis muaj qhov tsis zoo, ci ntsa iab tuaj tawm ntawm pwm, npaj rau nkoj. Qhov ntawd yog kev npau suav kev lag luam. Qhov tseeb, kev sib tsoo txhua hnub, yog kev sib tham tas li ntawm qhov zoo tshaj plaws geometry ntawm CAD qauv thiab cov tawv nqaij tawv ntawm cov hlau molten. Nws tsis yog hais txog nruj tolerances; Nws yog hais txog kev kwv yees, rov ua kom nruj dua nyob rau hauv ib pawg ntawm 50 lossis 5000, tshwj xeeb tshaj yog thaum koj tab tom cuam tshuam nrog txoj hauv kev nyuaj lossis cov phab ntsa nyias nyias uas yuav ua rau lub tshuab ua haujlwm hws. Ntau tus neeg siv khoom xav tias nws tsuas yog qhov zoo dua ntawm cov xuab zeb casting, tab sis qhov sib txawv ntawm cov txheej txheem tswj, cov khoom siv, thiab tom qab ua tiav yog ntau dua li chasm.
Lub hauv paus ntawm Precision: Nws yog qhov system, tsis yog kauj ruam
Muaj tseeb high precision casting, tsawg kawg hauv kuv qhov kev xav, pib ntev ua ntej lub cub tawg raug rho tawm haujlwm. Nws yog rooted nyob rau hauv thawj txheej txheem xaiv. Rau peb, feem ntau txhais tau tias peev casting lossis plhaub pwm casting. Qhov kev xaiv tsis yog arbitrary. Yog tias ib feem muaj qhov sib sib zog nqus, sab hauv rov nkag los yog xav tau qhov chaw ua tiav zoo dua li Ra 6.3, peev casting feem ntau yog tib txoj hauv kev. Tab sis kuv tau pom tej yaam num ua tsis tiav vim qhov kev txiav txim siab no tau ua tiav ntawm daim ntawv qhia kev kam rau siab yam tsis xav txog cov hlau. Piv txwv li, nickel alloy high-nickel coj txawv txawv thaum lub sij hawm solidification nyob rau hauv ceramic plhaub piv rau cov pa roj carbon steel - qhov yuav tsum tau noj, kev pheej hmoo ntawm kub tearing, lawv nyob rau lwm theem.
Qhov no yog qhov uas 30-khoom xyoo ntawm kev ua haujlwm rau lub tuam txhab xws li Qingdao Qiangsenyuan Technology (QSY) qhov tseem ceeb. Nws tsis yog ib daim paib rau ntawm lub vev xaib; nws yog ib tug sau, yuav luag intuitive lub tsev qiv ntawv uas alloys ua si zoo nrog cov txheej txheem. Koj tuaj yeem nyeem txog qhov shrinkage tus nqi ntawm 17-4PH stainless hlau, tab sis paub yuav ua li cas kho lub rooj vag system kom haum raws li qhov shrinkage ntawm lub turbine hniav vaj tse, raws li txoj haujlwm zoo sib xws los ntawm tsib xyoos dhau los, yog qhov tseeb tiag. Lawv tsom ntsoov rau cov alloys tshwj xeeb, xws li cobalt thiab nickel-raws li, tsis yog ib daim ntawv teev cov khoom siv xwb; nws txhais tau hais tias lawv yuav tau sib ntaus sib tua thiab daws cov teeb meem distortion uas muaj nyob rau hauv cov ntaub ntawv ua tau zoo.
Lub machining sab, CNC kev koom ua ke lawv hais, yog tsis-negotiable. Txhua tus neeg thov qhov tseeb siab precision yam tsis muaj kev ua haujlwm hauv tsev yog outsourcing lub sijhawm tseem ceeb tshaj plaws. Vim li cas? Vim hais tias koj datum nta yuav tsum tau machined nyob rau hauv ib tug tib teeb txheeb ze rau lub cam khwb cia geometry. Yog tias koj nrum lub flange nrog ib tug ± 0.2mm kam rau ua rau lub bolt lub voj voog, thiab ces xa mus rau ib tug thib peb-tog tshuab khw uas re-clamps nws, koj twb poob lub pedigree ntawm qhov precision. Lub peev xwm mus los ntawm lub plhaub pwm los yog peev casting ncaj qha mus rau CNC zeb nyob rau hauv ib puag ncig tswj yog dab tsi seals qhov seem kev ncaj ncees.
Qhov twg txoj kev xav ntsib qhov (Qee zaum ntxhov) Kev muaj tiag
Ib rooj plaub uas sticks nrog kuv koom nrog ib tug manifold rau ib tug hydraulic xeem rig. Cov specs hu rau kev sib cuam tshuam sab hauv nrog ib txoj kab uas hla ntawm 12mm, kam rau siab ntawm ± 0.1mm, hauv 316 stainless. Ntawm daim ntawv, doable nrog high precision peev casting. Tus qauv CAD yog zoo meej. Thawj cov qauv tau tawm los saib zoo, tab sis thaum lub sij hawm ntsuas siab, peb tau xau. Tsis yog kev puas tsuaj, tab sis ib tug seep. Tus neeg ua txhaum? Tsis yog lub ntsiab bore kab, tab sis qhov hloov maj mam, yuav luag tsis tuaj yeem ntsuas qhov sib txawv ntawm qhov ncaj ntawm qhov 150mm-ntev sab hauv channel, tshwm sim los ntawm ib feeb ua haujlwm ntawm cov tub ntxhais ceramic thaum lub sij hawm nchuav. Lub precision yog muaj nyob rau hauv qhov ntev static, tab sis tsis nyob rau hauv kev sib dhos.
Peb daws nws, tab sis tsis yog los ntawm magically txhim kho lub casting kam rau ua. Qhov ntawd twb nyob ntawm nws qhov txwv. Qhov kev txhim kho yog kev sib koom tes rov tsim dua tshiab nrog cov neeg siv khoom: peb tau nce me ntsis ntawm lub npe bore loj thiab tau teev ib qho kev ua haujlwm honing tom qab-casting rau cov chaw foob tseem ceeb. Lub casting tau txais peb 95% nyob rau ntawd nrog loj heev txo qhov nyuaj (tsis tas yuav tho thiab ntsaws ntau qhov kev sib tshuam), thiab cov precision machining tiav txoj haujlwm. Qhov no yog lub tswv yim symbiosis. Nws tau qhia kuv tias qhov siab precision casting feem ntau yog hais txog kev paub txog qhov twg cov txheej txheem ntuj txwv yog thiab tsim cov kev ua haujlwm thib ob los ua kom tiav nws, tsis yog tawm tsam nws.
Lwm qhov kev mob taub hau yog qhov yuav tsum tau ua kom zoo nkauj. Ntau cov specs yuav thov kom muaj qhov tsis zoo li-cam khwb cia rau cov khoom pom tau zoo. Tab sis flawless txhais li cas? Puas yog me ntsis peev casting kev ntxhib los mos tau? Puas yog ib txoj kab faint parting los ntawm lub plhaub pwm yog qhov tsis xws luag? Peb tau kawm los tsim cov qauv ntawm lub cev nrog cov qib sib txawv ntawm cov yam ntxwv ntawm qhov pom zoo - daim ntawv cog lus pom nrog tus neeg siv khoom. Nws zam cov kev tsis sib haum xeeb tom qab kev xa khoom uas ib feem ua haujlwm zoo tag nrho tab sis raug tsis lees paub ntawm kev hu xov tooj zoo nkauj. Cov khoom no yeej tsis nyob rau hauv cov ntaub ntawv.
Khoom siv yog Wild Card
Ua hauj lwm nrog cov tshwj xeeb alloys QSY cov npe, zoo li cov nickel-based sawv daws yuav, yeej cais cov xws li los ntawm kev cog lus. Cov ntaub ntawv no muaj fluidity txaus ntshai piv rau cov qauv hlau. Koj xav tias koj tau tsim lub rooj vag zoo meej rau cov ntu nyias, tab sis cov hlau tsuas yog xav kom khov sai heev, ua rau txias kaw lossis khiav tsis raug. Qhov tseeb tsis yog los ntawm qhov yuam kev, tab sis los ntawm qhov tsis tiav. Qhov kev ua haujlwm feem ntau suav nrog kev ua kom sov cov hlau ntau dua li niaj zaus thiab siv ntau cov pwm kub preheats, uas tom qab ntawd qhia txog nws tus kheej cov teeb meem nrog kev loj hlob ntawm cov qoob loo thiab muaj peev xwm ua rau lub ntsej muag nrog lub plhaub ceramic. Nws yog ib qho kev ntsuas ntsuas qhov twg tus metallurgist lub tswv yim yog qhov tseem ceeb raws li tus kws tsim khoom tsim khoom.
Kev ntsuas ntsuas
Koj tsis tuaj yeem thov qhov tseeb yam tsis tau txheeb xyuas nws, thiab qhov ntawd yog nws lub qhov luav. Ib qho pitfall feem ntau yog ntsuas ntau dhau. Muab CMM sojntsuam rau txhua qhov chaw ntawm ib qho nyuaj casting yog kim thiab siv sijhawm. Tus yuam sij yog txheeb xyuas qhov tseem ceeb-rau-function (CTF) nta-feem ntau yog cov mating nto, bore qhov chaw, thiab tshwj xeeb phab ntsa thicknesses-thiab tsom rau cov txheej txheem ntsuas nyob rau ntawd. Rau lwm qhov, qhov chaw zoo nkauj uas tsis yog qhov tseem ceeb, qhov yooj yim mus / tsis mus ntsuas lossis txawm tias pom qhov pom tau txaus. Kuv tau nkim hnub los tsim cov ntaub ntawv tshuaj xyuas tag nrho uas tsis muaj leej twg siv, thaum ib nplooj ntawv qhia txog CTF cov ntaub ntawv yuav muaj txiaj ntsig ntau dua. Precision yuav tsum tau ua kom muaj txiaj ntsig zoo rau kev lag luam.
Qhov no txuas rov qab mus rau kev sib xyaw machining. Feem ntau, thawj machining dhau ntawm qhov chaw datum yog qhov kev tshuaj xyuas tshaj plaws. Koj siv lub 0.2 hli txiav tawm lub ntsej muag mounting thiab tam sim ntawd saib yog hais tias lub porosity los yog shrinkage nyob rau hauv cov nyiaj khwv tau los. Nws yog lub sijhawm tawm tswv yim tiag tiag uas lub chaw tsim khoom ib leeg tsis tau txais kom txog thaum lub lis piam tom qab, thaum qhov tsis lees paub rov qab los ntawm cov neeg siv khoom lub khw.
Yog li, Dab tsi yog Qhov Kev Xa Mus Los?
Tom qab tag nrho cov no, dab tsi yog koj tiag tiag yuav nrog lub siab precision casting txheej txheem? Koj tsis yog yuav ib feem nrog cov lej nruj. Koj tab tom yuav txo tus nqi tag nrho rau cov duab geometry. Koj tab tom yuav khoom ncaj ncees nyob rau hauv ib daim ntawv uas yuav txwv tsis pub welded los yog sib sau ua ke los ntawm ntau yam machined blocks. Koj tab tom yuav lub sij hawm txuag nyiaj los ntawm kev tshem tawm 80% ntawm cov khoom lag luam. Thiab koj tab tom yuav tus neeg muag khoom qhov kev txiav txim siab - lawv lub peev xwm los saib daim duab thiab hais tias, Lub vojvoog no yog qhov ntse heev rau cov hlau uas koj tau teev tseg, nws yuav tsim kev ntxhov siab; cia peb kho nws rau X, lossis Peb tuaj yeem tuav qhov kev kam rau siab, tab sis nws yuav muab ob npaug rau tus nqi; Puas yog qhov chaw no puas cuam tshuam nrog lwm cov khoom?
Saib ntawm tus kws kho mob lub peev xwm, zoo li qhov tau teev tseg Qingdao Qiangsenyuan Technology qhov chaw (https://www.tsingtaocnc.com), kev sib xyaw ua ke ntawm cov txheej txheem casting tshwj xeeb, kev paub txog cov khoom siv, thiab hauv tsev CNC machining yog cov pov thawj pom tseeb ntawm qhov muaj peev xwm. Nws qhia tau hais tias kev teeb tsa tsim los tswj hwm tag nrho cov txiaj ntsig ntawm kev tsim kom muaj kev sib koom ua ke, tsis yog ib qho txuas hauv ib qho kev sib cais thiab yuam kev. Qhov kev sim tiag tiag, ib txwm, yog nyob rau hauv theem prototyping. Qhov ntawd yog qhov kev xav, lub vev xaib thov, thiab ntau xyoo ntawm kev paub los ua ke hauv ib qho haujlwm lossis poob sib nrug. Tsis muaj qhov zais cia hauv tsab ntawv tshuaj xyuas thawj zaug.
Thaum kawg, high precision casting yog ib tug paub tab, incredibly pab tau technology, tab sis nws tsis yog khawv koob. Nws yog ib qho khoom siv tes ua txhawb nqa los ntawm kev tshawb fawb thiab ntau yam kev daws teeb meem. Cov txiaj ntsig zoo tshaj plaws yog los ntawm kev kho nws raws li kev sib koom tes tsim thiab tsim kev sib koom tes los ntawm kev kos duab thawj zaug, tsis yog kev ua haujlwm ntawm lub thawv dub. Lub precision yog ntau npaum li nyob rau hauv kev sib txuas lus thiab kev npaj raws li nws yog nyob rau hauv cov hlau nws tus kheej.
