Thaum ib tug neeg nug txog tus nqi poob wax casting, feem ntau cov neeg muag khoom, suav nrog peb, instinctively xav txog muab tus nqi ib-kilo. Qhov ntawd yog kev lag luam shorthand, tab sis nws kuj yog qhov uas thawj qhov kev nkag siab yuam kev loj tshwm sim. Nqe tsis yog hais txog qhov hnyav ntawm cov hlau; Nws yog hais txog txhua yam koj tsis pom hauv CAD cov ntaub ntawv. Kuv tau siv ntau xyoo ntawm QSY (Qingdao Qiangsenyuan Technology Co., Ltd.), thiab thawj zaj lus qhia yog tias tus neeg siv khoom poob siab ntawm cov lus kawg feem ntau tshwm sim los ntawm qhov kev ua kom yooj yim. Lawv pom ib feem ntawm 5kg stainless hlau thiab cia siab tias tus nqi linear. Qhov tseeb yog, cov poob ciab casting nqi rau qhov ntawd tuaj yeem ua viav vias 300% raws li qhov lawv tseem tsis tau xav txog.
Qhov twg Tus Nqi Tiag Hides nyob rau hauv tus txheej txheem
Cia peb rhuav tshem tus nqi tsav tsheb tsis pom. Cov qauv siv quav ciab theem yog dag. Ib tug complex geometry tej zaum yuav xav tau ib tug ntau yam tuag los yog soluble siv quav ciab cores, uas skyrockets tus nqi tooling ua ntej ib tug ib tug hlau poob yog poured. Qhov no tsis yog machining qhov twg koj tsuas yog program rau txoj kev; Ntawm no, txhua qhov kev txiav thiab cov phab ntsa nyias xav tau lub tswv yim rau kev txhaj tshuaj wax, sib dhos, thiab lub plhaub tsev. Kuv nco qab txog lub twj tso kua mis impeller qhov project qhov kev tsocai thawj zaug yog raws li tus qauv siv quav ciab. Tus neeg siv tweak rau cov hniav profile txhais tau tias peb yuav tsum tau hloov mus rau silicone roj hmab pwm rau cov qauv siv quav ciab. Lub tsev poob ciab casting nqi ze li ob npaug, tsis yog los ntawm cov hlau, tab sis los ntawm kev siv zog ua haujlwm, cov txheej txheem qis-yield wax.
Ces los lub plhaub. Tus qauv ceramic plhaub rau cov hlau yuav xav tau 7 txheej. Rau lub siab kub nickel-based alloy? Koj tab tom saib 9-11 txheej, nrog cov ntaub ntawv tshwj xeeb refractory thiab tswj lub sij hawm ziab. Txhua txheej yog ua haujlwm, khoom siv, thiab lub sijhawm ua kom sov. Yog hais tias ib feem muaj qhov tob, nqaim kab noj hniav, ua kom lub plhaub zoo meej yam tsis muaj voids los yog tawg ua ib qho khoom siv tes ua. Peb tau muaj qhov chaw nyob qhov twg lub plhaub nqi ib chav tsev outweighed cov khoom nqi ntawm 17-4PH stainless hlau sab hauv. Qhov ntawd yeej tsis tshwm sim hauv ib qho yooj yim ib kg hauv internet laij lej.
De-waxing thiab firing zoo li cov kauj ruam yooj yim, tab sis lawv yog lub zog hogs. Lub autoclave rau chav de-waxing thiab qhov kub-kub rauv rau sintering lub plhaub khiav rau teev. Nrog rau cov nqi hluav taws xob thoob ntiaj teb tsis hloov pauv, qhov no yog qhov ncaj qha thiab feem ntau tsis tuaj yeem txiav txim siab mus rau qhov kawg peev casting nqi. Lub voj voog rau lub tshuab hluav taws xob rau ib pawg ntawm cobalt alloy qhov chaw tuaj yeem yog qhov chaw tus nqi tseem ceeb, ib yam dab tsi uas tus neeg siv khoom xaj 50 daim yuav tsis nyob hauv.
Khoom siv: Pom pom tseeb thiab tsis pom tseeb cuam tshuam
Yog lawm, 316L stainless yog kim dua ib kilo dua carbon steel. Qhov ntawd yog qhov yooj yim. Qhov nyuaj yog li cas cov khoom coj. Aluminium alloys pheej yig dua tab sis tuaj yeem ua gassy, ua rau cov khoom seem ntau dua. Nickel-raws li alloys zoo li Inconel 718 muaj kev ua haujlwm txaus ntshai tab sis kev ua haujlwm kub zoo heev. Tus nqi tsis yog lub ingot xwb; nws yog lub peev xwm rau cov kua muag kub thaum lub sij hawm solidification, xav tau kev tswj kom txias, thiab ntxiv machining nyiaj uas koj yuav tsum tau tawm vim hais tias koj tsis tuaj yeem kwv yees distortion zoo kawg nkaus.
Peb ua hauj lwm nrog tshwj xeeb alloys ntawm QSY. Ib qhov project rau lub turbine tivthaiv yuav tsum muaj ib tug proprietary cobalt-raws li alloy. Cov khoom siv raw khoom raug nqi, tab sis tus nqi tiag tiag yog kev kho cua sov tom qab casting. Nws xav tau ib qho kev daws teeb meem tshwj xeeb rau lub voj voog hauv lub tshuab nqus tsev kom ua tiav cov qauv nplej uas xav tau. Qhov kev kho cua sov ib kauj ruam ntxiv 40% rau tus nqi ua haujlwm. Thaum koj nrog plhaub molding ntawm superalloys, tus nqi yog ntau npaum li cas nyob rau hauv cov txheej txheem tom qab ua raws li nyob rau hauv lub casting nws tus kheej.
Tus nqi seem yog tus neeg tua neeg uas ntsiag to ntawm txhua qhov peev nyiaj. Rau cov duab yooj yim hauv cov hlau nplaum, peb yuav ntaus 95% tawm los. Rau qhov nyias-walled, intricate stainless hlau enclosure, 70% tawm los yog kev vam meej. Qhov poob 30% tsis yog hlau xwb; Nws yog tag nrho cov ciab, plhaub, kev ua haujlwm, thiab lub zog uas tau mus rau hauv cov ntawv ua tsis tiav, amortized rau hauv tus nqi ntawm qhov zoo. Qhov no yog qhov kev paub tseem ceeb. Ib tug zoo foundry engineer yuav saib tus qauv tsim thiab kwv yees cov teeb meem me ntsis - cov ntse thermal junctions uas yuav ua rau shrinkage porosity - thiab qhov tseem ceeb uas yuav ua rau muaj kev pheej hmoo rau cov lus los ntawm QSY.
Lub Machining Finish: Qhov twg Casting nqi tiag tiag Blends
Qhov no yog qhov tseem ceeb. Tsawg heev uas ploj lawm wax castings yog net-puab. Yuav luag txhua tus xav tau CNC machining rau qhov tseem ceeb interfaces - xov, sealing nto, precision bores. Cov poob ciab casting nqi feem ntau tsuas yog daim pib nkag. Kev sib koom ua ke nrog machining yog qhov uas tus nqi tag nrho raug txhais. Kev ua tsis zoo nrog cov phab ntsa tuab tsis sib xws lossis qhov nyuaj uas tsis xav txog yuav ua rau cov cuab yeej machining puas thiab lub sijhawm.
Peb qhov kom zoo dua ntawm Qingdao Qiangsenyuan yog kev sib koom ua ke ntsug. Peb ua qhov CNC machining hauv tsev. Qhov no txhais tau hais tias thaum kuv hais ib qho casting, kuv twb xav txog yuav ua li cas nws yuav fixtured ntawm lub zeb, uas datum nto peb yuav tshuab ua ntej, thiab ntau npaum li cas Tshuag tawm. Kuv twb pom quotes los ntawm qhov chaw uas tsuas cam khwb cia; lawv muab tus lej tsawg, tab sis tom qab ntawd tus neeg siv khoom raug ntaus nrog ib qho loj heev, tsis paub txog machining nqi los ntawm ib lub khw cais. Peb cov quotes tej zaum yuav zoo dua pib, tab sis lawv npog ib tug tiav, haumxeeb tivthaiv. Rau lub cev valve xyoo tas los, peb tau hais txog kev hloov kho lub kaum sab xis me ntsis uas ntxiv cov nqi tsis txaus ntseeg rau lub casting tab sis txo lub sijhawm ua haujlwm los ntawm 3 teev ib feem. Qhov ntawd yog kev txuag nqi tiag.
Qhov yuav tsum tau ua kom tiav yog lwm tus tsav tsheb maj mam. Raws li-cast nto (CT7-8) yog tus qauv. Tab sis yog tias koj xav tau CT5 du rau hydraulic foob lossis iav hlaws blasted rau kev thov kom zoo nkauj, qhov ntawd yog kev tuav ntxiv. Yog tias koj xav tau NDT tag nrho saum npoo zoo li kev sim nkag mus, qhov ntawd yog lwm yam kab. Cov no yog cov ntsiab lus uas tau txais glossed hauv email thaum ntxov tab sis dhau los ua cov ntsiab lus tseem ceeb hauv kev sib tham zaum kawg.
Volume thiab Tooling: Tus Nqi Tsis Ncaj Ncees
Tooling yog tus nqi ruaj. Rau ib tus qauv tsim tawm, peb yuav siv 3D-luam cov qauv los yog cov cuab yeej ceev-thiab-ntxuav. Tus nqi tsev yog siab vim tus nqi cuab yeej yog amortized tshaj ib thooj. Rau 10,000 daim, koj nqis peev rau cov hlau tawv tawv tuag rau kev txhaj tshuaj. Chav tsev nqi poob qis. Crossover point yog txawv rau txhua feem. Kuv feem ntau yuav tsum tau piav qhia rau cov neeg siv khoom tias xaj 100 daim yuav tsis yog 100 npaug ntawm tus nqi ntawm 1 daim; nws yuav tsuas yog 30 zaug, vim tias cov cuab yeej tau nthuav tawm.
Tab sis muaj ib tug ntxiab. Kev cog lus rau cov cuab yeej siv hluav taws xob siab rau ib feem uas tsis tau lees paub yog qhov txaus ntshai. Peb feem ntau pom zoo kom ib kauj ruam zuj zus: tus qauv nrog cov cuab yeej muag muag, kev tsav tsheb khiav ntawm 100 nrog kev txhim kho cov cuab yeej, tom qab ntawd tag nrho cov khoom. Qhov no cuam tshuam rau peev casting nqi txoj kev. Koj tuaj yeem pom peb txoj hauv kev rau cov txheej txheem ua haujlwm no ntawm peb qhov chaw ntawm https://www.tsingtaocnc.com, qhov chaw uas peb qhia txog seb peb tswj cov haujlwm li cas los ntawm cov qauv mus rau cov khoom loj.
Kev tu cov cuab yeej siv ntev ntev yog qhov zais cia. Wax txhaj pwm hnav. Ntau tshaj 50,000 lub voj voog, cov pwm hlau yuav xav tau polishing lossis rov txiav kom tswj tau cov qauv raug. Ib qho kev tsocai zoo tsim nyob rau hauv qhov xwm txheej rau kev kho dua tshiab, lossis qhia meej meej txog qhov suav lav rau thawj lub cuab yeej. Qhov no yog hom gritty nthuav dav koj tsuas yog kawm los ntawm kev khiav cov kab ntau lawm ntau xyoo, raws li peb muaj ntawm QSY tshaj peb 30 xyoo hauv kev casting thiab machining.
Yog li, Yuav Ua Li Cas Koj Tau Txais Cov Lus Cog Tseg?
Kom tau ib tug tiag tiag poob ciab casting nqi, tsis txhob xa ib daim ntawv CAD thiab nug ntau npaum li cas?. Muab cov ntsiab lus. Dab tsi yog qhov ntim txhua xyoo kwv yees? Dab tsi yog qhov tseem ceeb txaus siab (hu rau peb qhov tseem ceeb tshaj plaws)? Dab tsi yog cov khoom siv tshwj xeeb - tsis yog cov hlau tsis muaj steel, tab sis qib tiag tiag zoo li 304 lossis CF8M? Yuav ua li cas tom qab ua tiav? Kub kho? Plating? PMI puv? Cov ncauj lus kom ntxaws RFQ tso cai rau peb ua qauv ntawm cov txheej txheem tiag tiag.
Qhib rau Design for Manufacturability (DFM) tawm tswv yim. Ib lub vojvoog me ntsis nce ntxiv, cov phab ntsa tuab dua qub, lossis qhov chaw tweaked qhov chaw tuaj yeem txhim kho cov txiaj ntsig zoo thiab txo tus nqi. Kev sib raug zoo ntawm cov neeg siv khoom yog kev sib koom tes. Tsis ntev los no peb tau ua hauj lwm nrog ib tug engineer uas yog adamant txog xoom-draft sab hauv feature. Tom qab piav qhia txog qhov xav tau ntawm cov ceramic cores complex thiab cov khoom seem uas muaj feem cuam tshuam, lawv tau pom zoo rau qhov tsawg kawg nkaus. Cov peev casting nqi poob los ntawm 22%, thiab qhov ua haujlwm zoo ib yam.
Thaum kawg, nkag siab tias qhov pheej yig tshaj pib nqe lus feem ntau yog tus nqi kim tshaj plaws. Lub hauv paus txiav cov ces kaum ntawm cov khoom siv plhaub lossis kev kho cua sov yuav xa cov khoom uas tsis ua haujlwm hauv machining lossis, phem dua, hauv thaj chaw. Tus nqi yuav tsum muaj kev cuam tshuam cov txheej txheem ruaj khov uas ua rau muaj kev sib xws. Nws yog hais txog tus nqi, tsis yog tus nqi xwb. Tom qab peb lub xyoos dhau los, qhov ntawd yog qhov tseem ceeb ntawm qhov peb muab ntawm Qingdao Qiangsenyuan Technology: tus nqi tiag tiag rau qhov kev ntseeg siab, qhov twg txhua tus nqi raug suav nrog, tsis zais.
