Thaum cov neeg feem coob hnov 'sand casting foundry,' lawv daim duab qias neeg, chaotic khw pouring qhov chaw hlau. Qhov ntawd yog thawj qhov kev xav tsis zoo. Qhov tseeb, tshwj xeeb tshaj yog nyob rau hauv ib qho chaw uas muaj cov hauv paus hniav sib sib zog nqus zoo li Qingdao, yog txheej ntawm nuance. Nws tsis yog hais txog kev ua pwm los ntawm cov xuab zeb; Nws yog hais txog kev tswj cov kev hloov pauv feem ntau yeej tsis pom - cov dej noo hauv cov xuab zeb, kev tsim lub rooj vag, cov khoom sib zog. Kuv tau pom ntau txoj haujlwm ua tsis tiav vim tias ib tus neeg tau kho cov xuab zeb casting ua ib qho yooj yim, qis-tech backup txoj kev npaj. Nws yog dab tsi tab sis.
Lub hauv paus: Nws yog txhua yam hais txog cov xuab zeb (Thiab nws tsis yog xuab zeb xwb)
Wb tau qhov no ncaj. Cov 'xuab zeb' yog ib qho sib tov - silica xuab zeb, av nplaum (bentonite), dej, thiab feem ntau ntxiv xws li cov hmoov av los yog dej hiav txwv. Qhov ratio yog txhua yam. Cov dej noo ntau dhau, thiab koj tau txais cov cua tshuab, tawm hauv cov kab noj hniav. Tsawg dhau, thiab cov pwm tsis muaj zog ntsuab, tawg thaum lub sij hawm nchuav. Kuv nco qab ib pawg ntawm cov hlua hlau uas ua rau pom qhov khawb ntawm qhov chaw. Peb xyuas cov hlau, qhov kub thiab txias, txhua yam. Tig tawm, cov xuab zeb tov dej hauv dej muaj me ntsis calibration drift. Kev hloov pauv ntawm 0.5% ntawm cov dej noo txaus txaus los rhuav tshem cov khoom tsim tawm ib lub lim tiam. Qhov ntawd yog qhov tseeb zais hauv cov txheej txheem 'yooj yim'.
Tom qab ntawd muaj pwm-ua nws tus kheej. Muaj ntsuab xuab zeb molding, uas yog feem ntau, thiab ces resin-bonded xuab zeb zoo li nyob rau hauv plhaub molding los yog txias-box txheej txheem. Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), piv txwv li, teev plhaub pwm casting ua ib qho tshwj xeeb. Qhov ntawd yog ib tug tsiaj nyaum txawv. Nws siv resin-coated xuab zeb los ua ib qho nyias, tawv plhaub nyob ib ncig ntawm cov qauv rhuab. Qhov tseeb qhov tseeb yog deb tshaj li cov xuab zeb ntsuab. Yog li thaum koj tab tom saib lub peev xwm ntawm lub hauv paus, koj tsis tuaj yeem pom 'xuab zeb casting.' Koj yuav tsum nug: dab tsi ntawm cov txheej txheem xuab zeb peb tham txog?
Kev tsim qauv yog lwm yam kev kos duab tsis zoo. Ntoo patterns warp. Cov qauv hlau yog kim tab sis kawg. Rau qhov nyuaj, koj yuav xav tau ntau qhov qauv nrog cov cores. Tsim tus qauv tsis yog tsuas yog luam ib feem; koj yuav tsum suav rau qhov shrinkage - sib txawv rau cov hlau, hlau, lossis txhuas - thiab cov kaum sab xis kom cov qauv tuaj yeem rub tawm ntawm cov xuab zeb kom huv si. Nws yog thawj kauj ruam uas tsim rau manufacturability yog tshwm sim los yog tau ignored, teem lub theem rau tag nrho cov downstream kev vam meej los yog mob taub hau.
Qhov twg Sand Casting Fits (Thiab qhov twg nws tsis)
Sand casting qhov chaw qab zib yog qhov tsawg-rau-nruab nrab ntim ntau lawm ntawm nruab nrab-rau-loj qhov chaw. Xav txog cov twj tso kua mis, cov cuab yeej siv lub hauv paus, lub cev lub cev, cov iav loj loj. Nws yog qhov zoo heev rau kev tsim qauv yooj yim thiab tuav ntau yam ntawm cov alloys, los ntawm cov hlau cam khwb cia rau cov hlau tshwj xeeb xws li cov nickel-based. Lub website rau QSY hais txog kev ua haujlwm nrog cov alloys tshwj xeeb, uas ua rau kev nkag siab zoo. Pouring tus nqi siab, nyuaj-rau-machine alloys rau hauv cov xuab zeb pwm tuaj yeem siv nyiaj ntau dua li pib nrog lub pob loj loj thiab ua haujlwm tawm ntawm 80% ntawm nws.
Tab sis nws tsis yog rau txhua yam. Yog hais tias koj xav tau ultra-nplua nto finishes los yog tolerances nruj dua, hais, ± 0.5mm ntawm ib tug 100mm dimension, koj nyob nraum thawb nws. Qhov ntawd yog qhov uas cov txheej txheem zoo li peev casting (uas lawv kuj ua) coj mus. Kev ua haujlwm tom qab casting yog qhov tseem ceeb heev. Txhua feem los nrog flash (hlau ntau dhau ntawm pwm seams), sprues, thiab rooj vag txuas. Qhov ntawd yog qhov chaw machining sab, lub CNC machining muaj peev xwm ua haujlwm puv npo zoo li QSY muab, dhau los ua qhov sib cais los ntawm cov txheej txheem casting. Koj tsis tuaj yeem xa cov khoom tiav tsis muaj nws.
Kuv nco qab txog qhov project rau marine cav tivthaiv hauv stainless hlau. Lub geometry tau yooj yim txaus rau cov xuab zeb casting, tab sis cov lus qhia corrosion yog lim hiam. Peb yuav tsum tau ceev faj nrog cov pwm txheej kom tiv thaiv cov hlau-pwm cov tshuaj tiv thaiv thiab xyuas kom meej qhov chaw. Nws ua haujlwm, tab sis cov npoo ntawm qhov yuam kev yog slim. Nws underscored tias cov ntaub ntawv xaiv dictates koj cov txheej txheem tsis ntau npaum li qhov zoo li ib feem.
Kev mob taub hau Inevitable: Porosity, Shrinkage, thiab Shakeout
Tsis zoo. Txhua foundry engineer kev sib ntaus sib tua txhua hnub. Nrog cov xuab zeb casting, roj porosity thiab shrinkage kab noj hniav yog cov neeg xav tias ib txwm. Porosity feem ntau yog los ntawm pwm. Yog hais tias cov xuab zeb tsis zoo vented los yog ntub heev, cov pa roj nkag mus rau hauv cov hlau thaum nws solidifies. Koj pom cov pinholes thaum lub sij hawm machining lossis kev sim siab. Shrinkage yog qhov teeb meem thermal. Raws li hlau txias, nws cog lus. Yog tias koj tsis tsim cov risers (feeders) kom raug los muab cov hlau ua kua rau cov chaw khov, koj tau txais cov voids sab hauv. Khoos phis tawj simulation pab tam sim no, tab sis tsis muaj qhov hloov pauv rau kev paub hauv riser qhov chaw.
Shakeout-khaws cov xuab zeb tawm ntawm qhov txias txias-yog qhov cuam tshuam ntau dua li nws lub suab. Ua nws ntxov dhau, thiab cov casting tuaj yeem cuam tshuam los yog tawg los ntawm qhov seem seem. Ua nws lig dhau lawm, thiab koj lub caj dab ntau lawm. Cov xuab zeb yuav tsum tau rov qab, txias, thiab rov kho dua. Qhov kub, tsis muaj zog xuab zeb reclamation system yuav choke koj tag nrho cov haujlwm. Kuv tau nyob hauv cov chaw tsim khoom uas qhov ntsuas kub nyob ze ntawm qhov chaw nres tsheb shakeout tsis tuaj yeem tiv taus, thiab cov xuab zeb zoo raug kev txom nyem, tsim kom muaj lub voj voog tsis zoo.
Tom qab ntawd muaj chav ntxuav. Nws siv zog ua haujlwm, nrov nrov, thiab plua plav. Sib tsoo tawm cov rooj vag, tua blasting kom huv si. Nws yog qhov chaw uas ntxhib casting pib zoo li ib feem. Automation tab tom nkag mus rau ntawm no, tab sis rau ntau qhov chaw ua haujlwm, qhov no tseem yog ib qho kev sib koom tes, nyob ntawm kev txawj ntse. Qhov zoo ntawm qhov kawg ntawm tes ua tiav tuaj yeem ua los yog tawg ntawm qhov zoo li thiab qee zaum nws txoj haujlwm.
Kev sib koom ua ke nrog Machining: Ib Qhov Txuas Tsis Sib Tham
Tsis muaj cov khoom siv niaj hnub no muaj sia nyob ntawm kev ua ib leeg. Yuav luag txhua qhov xuab zeb-cam khwb cia yuav tsum tau siv lub tshuab rau ntawm qhov chaw tseem ceeb-bolt qhov, sealing ntsej muag, bearing rooj. Qhov no yog vim li cas tus qauv ntawm kev sib xyaw ua ke xuab zeb casting qhov chaw thiab lub khw muag khoom muaj zog heev. Thaum ob txheej txheem nyob rau hauv ib lub ru tsev, zoo li ntawm https://www.tsingtaocnc.com, kev sib txuas lus ncaj qha. Pab pawg machining tuaj yeem tawm tswv yim rau qhov chaw tsim khoom yog tias lawv tsis tu ncua nrhiav cov pob zeb nyuaj lossis hloov cov porosity hauv qee qhov chaw ntawm qhov casting, thiab cov pwm lossis cov txheej txheem tuaj yeem hloov kho.
Kuv tau pom lwm txoj hauv kev: ib lub tshuab ua hauv ib lub nroog, xa mus rau lub khw muag khoom hauv lwm qhov. Tus kws kho tshuab ntaus cov xuab zeb nyuaj thiab ua rau lub cuab yeej tawg. Lawv liam lub hauv paus rau 'cov hlau qias neeg.' Lub foundry liam tus qauv los yog machining tsis. Lub lis piam ntawm kev ncua tshwm sim. Integrated manufacturing txiav los ntawm qhov ntawd. Lub CNC programmer tseem tuaj yeem hais qhia ntxiv ib millimeter ntawm Tshuag ntawm lub ntsej muag uas feem ntau qhia me ntsis kev cuam tshuam, daws qhov teeb meem ua haujlwm.
Qhov no yog qhov tseem ceeb rau cov ntaub ntawv uas lawv hais txog - cam khwb cia hlau, hlau, stainless, cobalt thiab npib tsib xee alloys. Machining nickel-based alloy yog ib txoj haujlwm tshwj xeeb. Muaj cov kws tshaj lij machining hauv tsev txhais tau hais tias lub chaw tsim khoom nkag siab txog kev ua haujlwm ntawm qhov lawv tau nchuav los ntawm hnub ib. Lawv tuaj yeem xaiv cov qib pes tsawg alloy uas sib npaug cov khoom siv nrog cov kev xav tau tom qab ua tiav.
Kev lag luam ntawm Nws: Ntau tshaj Melting Hlau
Khiav ib tug foundry hnub no yog ib tug tightrope taug kev. Nws yog cov peev nyiaj siv zog (kuav, cov xuab zeb, tswj kev ua qias tuaj), lub zog tshaib plab, thiab ntsib cov nqi tsis txaus siab. Tus nqi-ntxiv yog tsis nyob rau hauv melting cov hlau; nws yog nyob rau hauv engineering. Tus nqi yog pab tus neeg siv khoom tsim ib feem uas cam khwb cia zoo, tshuab tau zoo, thiab ua tau zoo. Nws yog nyob rau hauv kev daws cov metallurgical puzzle rau ib daim ntawv thov tshwj xeeb.
Ib lub tuam txhab uas nyob ib ncig ntawm 30 xyoo, zoo li QSY, tau pom cov voj voog. Lawv tau yoog. Muab ntau yam txheej txheem casting (xuab zeb, plhaub, peev) thiab machining txhais tau tias lawv tuaj yeem coj tus neeg siv khoom mus rau kev tsim cov nqi tsim nyog tshaj plaws, tsis yog qhov lawv tshwm sim ua. Qhov ntawd yog lub cim ntawm kev ua haujlwm loj. Lub neej ntev qhia tau hais tias lawv tau taug kev qhov chaw ntawm cov xuab zeb sib xyaw, metallurgy, thiab cov saw hlau ntev txaus los tsim kom muaj kev paub tiag tiag.
Yog li, thaum koj ntsuas cov xuab zeb casting foundry, tsis txhob nug tus nqi ib kilogram xwb. Nug txog lawv cov txheej txheem tswj cov xuab zeb. Nug seb lawv tsim lawv lub rooj vag thiab nce siab li cas. Nug txog lawv lub peev xwm machining hauv tsev thiab seb lawv daws cov lus teb li cas ntawm cov chaw haujlwm. Cov lus teb yuav qhia rau koj paub ntau ntxiv txog koj qhov project qhov kev pheej hmoo ntawm kev vam meej tshaj li daim ntawv qhia glossy puas tau. Cov khoom siv tes ua yog nyob rau hauv kev tswj hwm qhov sib txawv, tsis yog lub ncuav.
