Thaum koj hnov txog kev nqis peev tsis txaus ntseeg, ua li cas rau lub siab? Rau ntau tus neeg, nws tsuas yog lo lus buzz- qee qhov kev cog lus tsis meej ntawm qhov zoo dua lossis tus nqi qis dua. Lub sij hawm tau muab pov tseg ntawm kev lag luam thiab hauv kev muag khoom, feem ntau tsis muaj ntau yam khoom. Hauv kev muaj tiag, kev txhim kho cov txheej txheem no tsis yog hais txog ib lub mos txwv khawv koob; nws yog grind. Nws yog hais txog cov txiaj ntsig ntawm ib puas me me kev hloov kho hauv lub plhaub chav tsev, chav ua haujlwm wax qauv, thiab hauv pem teb foundry. Ntau tus xav tias nws yog txhua yam txog kev yuav lub qhov cub tshiab lossis lub tshuab luam ntawv 3D zoo nkauj rau cov qauv. Qhov ntawd yog ib feem ntawm nws, paub meej, tab sis yog tias koj lub plhaub kaw lus tsis sib haum lossis koj qhov kev tsim lub rooj vag tsis zoo, cov khoom siv tshiab tsuas yog cov ntawv hnyav xwb. Kuv tau pom cov khw nchuav nyiaj rau hauv kev txhim kho uas tsis tau txav lub koob ntawm cov nqi seem.
Lub Foundation: Nws Ib txwm Hais Txog Lub Plhaub
Wb tau tiag tiag. Yog xav tham txog impro peev casting, koj yuav tsum pib nrog lub plhaub. Qhov no yog qhov uas feem ntau ntawm cov teeb meem - thiab cov cib fim - nyob. Kuv nco qab ua hauj lwm ntawm ib tug series ntawm stainless hlau impellers rau lub twj tso kua mis chaw tsim tshuaj paus. Cov spec hu ua rau nyias nyias, aerodynamic vanes. Peb cov khoom seem tau hovering nyob ib ncig ntawm 40% vim cov hlab ntsha thiab lub plhaub tawg. Peb caum cov neeg raug liam ib txwm: slurry viscosity, stucco xuab zeb gradation, ziab chav tsev av noo. Qhov kev tawg tsis yog qee qhov kev daws teeb meem siab; nws tau ua tib zoo kaw qhov ntsuas kub ntawm txhua lub voj voog hauv ob lub lis piam. Peb pom 5-degree Celsius poob thaum hmo ntuj ua haujlwm uas ua rau lub tsho tiv no tsis sib haum. Stabilizing uas pheej yig dua li cov khoom siv tshiab thiab txiav cov seem ntawm ib nrab. Kev txhim kho ntawm no yog mob granular.
Qhov no txuas ncaj qha mus rau kev tshaj lij ntawm kev ua haujlwm ntev. Coj ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Nrog ntau tshaj 30 xyoo nyob rau hauv casting thiab machining, lawv tau zoo li nyob los ntawm kev suav tsis txheeb ntawm daim ntawv qhia plhaub tweaks. Lawv tshwj xeeb hauv ob lub plhaub pwm thiab peev casting txhais tau hais tias lawv nkag siab txog cov ntaub ntawv kev tshawb fawb tob tob - yuav ua li cas sib txawv binders cuam tshuam nrog ntau yam stuccos, yuav ua li cas los tsim lub plhaub rau lub cev loj ntawm lub cev valve piv rau cov khoom siv cobalt alloy phais. Qhov kev paub ntawm lub koom haum zoo li no yog lub hauv paus ntawm kev txhim kho tiag tiag. Koj tsis tuaj yeem yuav nws ntawm lub txee.
Cov ntaub ntawv lawv tus kheej dictate txoj kev txhim kho. Ua haujlwm nrog nickel-based alloys? Koj lub plhaub lub thermal expansion profile thiab kub lub zog ua tsis yog-negotiable. Ib qho kev txhim kho me me ntawm zircon hmoov cov ntsiab lus ntawm lub ntsej muag lub tsho tuaj yeem yog qhov sib txawv ntawm lub suab nrov thiab ib qho riddled nrog kua muag kub. Nws tsis yog kev ua haujlwm zoo. Nws yog hais txog cov kws tshaj lij nrog ntau xyoo dhau los ntawm kev paub txog, los ntawm kev saib thiab kev xav ntawm lub slurry, yog tias nws yog, ntev ua ntej qhov kev xeem kuaj tau rov qab los.
Chav tsev ciab: Qhov chaw Dimensional Fidelity yeej los yog poob
Txhua leej txhua tus tsom ntsoov rau cov hlau, tab sis cov qauv siv quav ciab yog qhov casting's DNA. Tej yam tsis zoo ntawm no tau nthuav dav. Kev txhim kho hauv kev txhaj tshuaj yog kev sib ntaus sib tua tiv thaiv kev ntxhov siab sab hauv. Peb ib zaug muaj ib qhov project rau aerospace brackets uas peb tau txais kev hloov maj mam, tsis yog-uniform warpage tom qab dewaxing. CAD qauv yog zoo meej, cov cuab yeej tshiab. Tus neeg ua txhaum? Kev txhaj tshuaj ciab siab thiab tuav lub sijhawm tsis tau ua kom zoo rau qhov tshwj xeeb geometry qhov ntim-rau-nto-chaw piv. Peb yuav tsum tsim ib lub tsev qiv ntawv me me ntawm kev txhaj tshuaj tsis haum rau cov tsev neeg sib txawv ntawm cov duab sib txawv. Nws yog tedious, tab sis nws tshem tawm ib tug loj qhov chaw ntawm dimensional drift.
Qhov no yog qhov kev koom ua ke nrog machining, zoo li QSY's ua ke peev casting thiab CNC muaj peev xwm, qhia tau hais tias nws cov tswv yim muaj nqis. Yog tias koj tuaj yeem tsim qhov ze-net-shaped wax qauv ntawm precision machining ntawm tus tswv tuag, koj tab tom pib los ntawm ntau dua kev ncaj ncees hauv paus. Qhov kev txhim kho yog ci nyob rau hauv thaum pib. Tom qab ntawd, txhua qhov CNC machining tom ntej ntawm qhov kawg hlau yog qhov tsawg, khaws cov khoom ruaj khov thiab txuag nqi. Nws yog ib tug holistic saib ntawm manufacturing saw.
Lwm qhov uas feem ntau tsis saib xyuas yog kev sib sau ua ke. Cov kev txawj ntawm kev siv vuam sib dhos ua cov ntoo ncaj qha cuam tshuam cov txiaj ntsig. Lub rooj vag tsis zoo los yog qhov sib txuas tsis muaj zog yuav ua rau cov hlau khiav tawm los yog mistruns. Kev cob qhia thiab kev jigging yooj yim ntawm no muab kev xa rov qab loj heev. Kuv tau pom tias cov yeeb yaj kiab kaw ib tus neeg ua haujlwm paub txog cov txheej txheem thiab siv nws rau kev cob qhia txhim kho kev sib raug zoo ntau dua li cov txheej txheem automated uas peb tuaj yeem them tau thaum lub sijhawm.
The Melt and Pour: Control Over Chaos
Ntawm no yog qhov kev xav ntsib hluav taws. Koj tuaj yeem muaj lub plhaub zoo meej thiab cov qauv siv quav ciab zoo meej, thiab qhov tsis zoo nchuav ua rau txhua yam. Rau kuv, kev txhim kho cov txheej txheem casting nws tus kheej yog hais txog ruthless standardization thiab to taub lub physics ntawm sau. Nrog rau kub kub alloys xws li cobalt-based, kev tswj superheat yog qhov tseem ceeb. Ob peb degrees siab dhau lawm, thiab koj nce cov tshuaj tiv thaiv hlau-plhaub; tsawg dhau, thiab koj yuav raug mistruns.
Peb tau siv qhov kev hloov pauv yooj yim tab sis muaj txiaj ntsig zoo rau kev tso cov turbine hniav: hloov los ntawm lub caij nplooj zeeg dawb ncuav mus rau qhov kev tswj hwm, lub zog tilt ncuav nyob rau hauv ib daim pam me ntsis argon. Qhov txo qis hauv kev kub ntxhov thiab kev tsim oxide tau pom tam sim hauv cov duab hluav taws xob. Qhov kev txhim kho tsis yog nyob rau hauv cov khoom siv (txawm hais tias lub tilt ncuav ntaus ntawv yog custom-made) tab sis nyob rau hauv lub tswv yim - prioritizing laminar sau tshaj ceev. Qhov no yog hom txheej txheem nuance ntau xyoo caum foundry accumulates.
Tom qab-casting, txheej txheem khob tawm yog lwm qhov chaw txaus ntshai. Kuv tau pom zoo nkauj castings tawg los ntawm kev txaus siab dhau kev co lossis lub dav hlau dej teeb siab dhau lawm. Kev txhim kho txhais tau tias tsim kom muaj kev sib haum xeeb, cov khoom siv tshwj xeeb décoring txheej txheem, qee zaum txawm tias cov tshuaj leaching rau ultra-complex sab hauv. Nws yog ib qho qeeb, rov qab kawm nkhaus.
CNC Machining: Qhov tseem ceeb kawg kab
Qhov no yog kev them nyiaj. Ib tug zoo ua peev casting yuav tsum tau machining tsawg heev. Tab sis tsawg heev tsis txhais hais tias tsis muaj. Lub interface ntawm lub foundry thiab lub tshuab khw yog qhov twg ntiv tes tau taw. Qhov kev txhim kho tiag tiag yog los ntawm kev npaj ua ntej. Piv txwv li, ntawm kev ua haujlwm sib xyaw ua ke zoo li QSY, CNC programmers yuav tau sab laj nrog cov engineers foundry thaum lub sij hawm pib qhov rooj tsim. Lawv yuav pom zoo rau cov ntsiab lus datum, ntxiv cov khoom siv me me hauv cov chaw tseem ceeb, thiab tsim cov khoom siv uas hais txog cov yam ntxwv zoo li-cam khwb cia, tsis yog CAD qauv.
Kuv kawm qhov nyuaj no. Peb ib zaug nrum ib series ntawm marine-qib stainless hlau fittings. Lub casting yog qhov zoo, tab sis peb lub khw muag khoom tau tawm tsam vim qhov pib qhov rooj sab laug sab laug uas cuam tshuam nrog tus txheej txheem vise teeb. Lub rooj sib tham ob-teev nruab nrab ntawm cov casting thiab machining leads ua ntej lub cuab tam yuav tau txais kev cawmdim hnub ntawm fixture redesign tom qab. Kev txhim kho yog hais txog kev rhuav tshem lub tuam tsev silos.
Rau cov alloys nyuaj, machining lub tswv yim yog ib feem ntawm kev txhim kho. Paub tias cov npib tsib xee-raws li alloy casting muaj qhov sib txawv me ntsis, qhov sib txawv ntawm qhov sib txawv ntawm lub plhaub sib cuam tshuam txhais tau tias koj qhov kev pab cuam CNC yuav tsum muaj kev txiav txim siab ntau dua. Qhov kev paub no los ntawm kev pub cov ntaub ntawv rov qab machining (cov cuab yeej siv tus nqi, qhov ua tiav tiav) rau pab pawg tsim, kaw lub voj.
Kev ntsuas tiag tiag: Kev sib raug zoo thiab kev ntseeg siab
Yog li, dab tsi yog impro tiag xa? Nws tsis yog feem ntau yog cov khoom tshiab hloov pauv. Nws yog lub peev xwm los ntaus CTQ (Critical-rau-Quality) qhov ntev ntawm ib qho nyuaj, batch tom qab batch, rau daim ntawv cog lus uas kav kaum xyoo. Nws yog qhov kev ntseeg siab rau tus neeg siv khoom xws li cov cuab yeej kho mob lossis cov khoom siv hluav taws xob chaw tsim khoom hauv koj. Lawv tsis quav ntsej txog koj caj npab robotic tshiab; lawv saib xyuas tias txhua yam khoom hauv lawv lub rooj sib txoos haum thiab ua tau zoo.
Qhov no yog qhov chaw uas lub tuam txhab tsim nws lub koob npe nrov. Peb caug xyoo hauv kev lag luam, zoo li QSY, qhia tias lawv tau tshawb xyuas cov kev txhim kho ntxiv no ua tiav thoob plaws cov khoom hloov pauv thiab kev lag luam. Lawv txoj haujlwm nrog cov alloys tshwj xeeb qhia kuv tias lawv tau daws cov teeb meem nyuaj-tswj cov qauv nplej hauv cov ntu loj, tswj cov kev ntxhov siab seem, ua tiav X-ray zoo welds ntawm kho castings (thaum tso cai los ntawm spec).
Thaum kawg, txhim kho peev casting yog kev xav. Nws yog qhov txaus siab los khawb rau hauv 40% seem tus nqi rau hnub Friday yav tav su thiab tsis tawm mus txog thaum koj muaj qhov kev xav los sim rau hnub Monday. Nws muaj nuj nqis rau tus kws ua haujlwm qhov kev xav ntau npaum li lub spectrometer nyeem ntawv. Kev txhim kho yog nyob ntsiag to, ua rau hauv lub neej niaj hnub niaj hnub, thiab xav txog hauv pawg loj hlob ntawm kev xa khoom tiav rau qhov chaw uas tsis muaj leej twg xav kov. Qhov ntawd yog qhov kev ntsuas tiag tiag.
