Thaum ib tug neeg nug txog 'kev nqis peev casting nqi', kuv feem ntau xav tias lawv tab tom nrhiav tiag tiag. Puas yog nws tsuas yog tus lej los piv rau lwm tus neeg muag khoom, lossis lawv puas to taub dab tsi pub rau hauv daim duab kawg? Hauv kuv lub xyoo, kuv tau pom ntau yam haujlwm tsis zoo vim tias thawj qhov kev tsocai tau raug kho raws li tus nqi ruaj khov, thaum qhov tseeb, nws tsuas yog qhov pib ntawm kev sib tham. Tus nqi tiag tiag tsis yog rau cov hlau hauv ib feem xwb; nws yog rau tag nrho cov lus ntawm tig ib tug siv quav ciab qauv rau hauv ib tug tiav, haumxeeb tivthaiv. Cia peb tham txog dab tsi tiag tiag txav tus lej ntawd nce lossis nqis.
Qhov twg cov lej tiag los ntawm
Koj tau txais kev thov, tej zaum yog 3D qauv lossis txawm tias tsuas yog kos duab. Thawj qhov kev xav yog xam cov hlau hnyav thiab sib npaug. Qhov ntawd yog qhov yuam kev loj tshaj plaws. Cov peev casting nqi pib nrog pwm. Ib qho yooj yim, ob feem cuab yeej rau ib qho yooj yim iav yog ib yam. Tab sis yog hais tias ib feem muaj undercuts, nyias phab ntsa, los yog complex sab hauv raws, koj tab tom saib ib tug multi-slide pwm los yog ceramic cores. Tus nqi cuab yeej ntawd tau txais amortized, tab sis nws yog qhov tseeb, ua ntej ntaus. Kuv nco qab hais txog lub twj tso kua mis impeller; tus neeg siv khoom xav tsis thoob tias cov cuab yeej yog 70% ntawm thawj PO. Tab sis yog tias tsis muaj qhov sib dhos tseem ceeb, qhov tsuas yog ua tsis tau. Cov lus hais tsis siab; nws yog qhov tseeb.
Ces muaj wax. Tsis yog tag nrho cov wax yog tib yam. Rau high-precision qhov chaw, koj xav tau ib tug tsawg-shrinkage, high-stability sib tov. Nws raug nqi ntau dua. Cov txheej txheem siv quav ciab nws tus kheej-siab, kub, lub sijhawm voj voog-txhua yam cuam tshuam rau qhov zoo ntawm tus qauv thiab, yog li ntawd, cov txiaj ntsig. Ib qho qauv siv tsis zoo tuaj yeem lav lub plhaub tawg thiab cov hlau nkag tom qab, uas txhais tau tias seem. Thiab seem yog tus nqi uas ib txwm, ib txwm pom nws txoj hauv kev rov qab mus rau hauv peev casting nqi ib daim ntawm qhov kev txiav txim tom ntej, yog tias tus neeg muag khoom xav nyob hauv kev lag luam.
Cov ntaub ntawv xaiv yog qhov pom tseeb tsav tsheb, tab sis nws tsis yog linear. 304 stainless hlau yog qhov qub. Tab sis thaum koj dhia mus rau nickel-raws li alloy zoo li Inconel 718, koj tsis yog them rau cov khoom siv raw nqi xwb. Koj tau them nyiaj rau kev tswj hwm huab cua melting, tshwj xeeb tuav ntawm kev xa rov qab (gating thiab sprues), thiab feem ntau, cov txheej txheem ua kom qeeb qeeb qeeb los tiv thaiv kev tshwm sim. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb lub xyoo caum hauv casting thiab tshwj xeeb alloys, yuav ua rau qhov no instinctively. Lawv cov lus tsocai rau ib feem ntawm cobalt-raws li lub valve yuav raug teeb tsa txawv ntawm ib qho rau cov pa roj carbon steel bracket, txawm nyob rau tib qhov hnyav.
Ntxim Ntxim Ua Lawv Tsis Qhia Koj Txog
Qhov yuav tsum tau ua tiav. Ra 3.2 vs Ra 1.6. Qhov ntawd zoo li qhov sib txawv me me ntawm daim ntawv spec. Nyob rau hauv pem teb khw, nws yuav txhais tau hais tias ib tug ntxiv theem ntawm slurry txheej, ib tug finer stucco xuab zeb, los yog hloov los ntawm tus qauv fused silica mus rau ib tug zircon-raws li prime tsho tiv no. Txhua kauj ruam ntxiv sijhawm, nqi khoom, thiab kev ua haujlwm. Yog tias koj hu tawm 'as-casting' tiav, tus nqi poob. Tab sis yog tias koj xav tau ib qho chaw npaj rau plating los yog kub-kub txheej, lub plhaub txheej txheem yuav kim dua. Qhov no tsis tshua tawg tawm hauv ib qho yooj yim quote; nws yog ci rau hauv ib-kg tus nqi.
Order kom muaj nuj nqis thiab repeatability. Classic kev lag luam ntawm nplai siv, tab sis nrog kev sib tw. Kev khiav ntawm 10,000 daim tso cai rau kev txhim kho qhov rooj, qhov twg koj tuaj yeem ua pawg 20 feem ntawm tsob ntoo. Unit nqi poob. Tab sis rau 50 daim? Koj tseem tab tom tsim lub plhaub tag nrho rau tsob ntoo uas tsuas tuav tau 4 ntu xwb. Kev ua haujlwm los sib sau ua ke, poob, thiab stucco yog yuav luag tib yam. Tus nqi tsev yog siab, thiab yog li ntawd. Qhov no yog qhov uas cov neeg yuav khoom tshiab tau ntxhov siab. Lawv pom 'siab' peev casting nqi rau tus qauv khiav thiab taug kev deb, tsis paub tias tus nqi qauv rau qhov ntim qis yog qhov sib txawv. QSY tus qauv, npog los ntawm pwm-ua rau CNC machining, yeej pab tau ntawm no. Lawv tuaj yeem nqus tau qee qhov kev ua haujlwm tsis zoo yog tias lawv pom txoj hauv kev rau ntim ntau lawm thiab ua haujlwm tom qab machining.
Kev xeem thiab ntawv pov thawj. Ua rau cov ntawv luam yog pheej yig. Ua rau nws luam tawm thiab muab cov ntaub ntawv pov thawj tag nrho rau ASTM A985, nrog 100% radiographic tshuaj xyuas yog cov tsiaj nyaum sib txawv. Txhua qhov kev tshuaj xyuas-dye penetrant, X-ray, CMM-ntxiv cov nqi tas thiab sib txawv. Kuv twb muaj tej yaam num uas qhov kev xeem raws tu qauv nqi ntau tshaj qhov casting nws tus kheej. Nws tsis yog markup; nws yog kev pov hwm thiab pov thawj. Yog tias koj nyob hauv aerospace lossis kev kho mob, qhov no yog tus nqi. Omitting nws los ntawm koj thawj RFQ kom tau txais tus nqi qis dua 'daim ntawv nplaum' yog daim ntawv qhia rau kev puas tsuaj thiab hloov cov xaj tom qab.
Qhov Teeb Meem Tiag: Qhov twg Tus Nqi Mus Tsis Zoo (thiab Txoj Cai)
Peb muaj ib tus neeg siv khoom ib zaug uas tau muab vaj tse rau daim ntawv thov marine. Lawv tau txais peb nqe lus. Peb qhov nruab nrab. Qhov qis tshaj plaws los ntawm lub khw me me uas tau cog lus rau lub hli. Ib feem yog nyob rau hauv 316 stainless. Cov neeg sib tw qis tau xa, tab sis cov khoom muaj micro-porosity. Tsis pom, tab sis nyob rau hauv siab, lawv leaked. Tus neeg siv khoom tau ntsib ib qho kev rov qab tag nrho. Cov peev casting nqi lawv them yog, thaum kawg, xoom, vim cov khoom tsis muaj nqis. Tus nqi ntawm kev ua tsis tiav - rov tsim dua tshiab, rov kho dua, ncua cov khoom lag luam tawm-dwarfed qhov sib txawv ntawm peb cov lus hais thiab qhov tsawg.
Peb ua li cas txawv? Peb cov txheej txheem, honed ntau xyoo zoo li ntawm QSY, suav nrog cov kauj ruam ua kom muaj zog rau qhov tshwj xeeb geometry los pub cov tuab-nyias junctions. Nws ntxiv ib lub voj voog lub sij hawm nplua. Peb cov lus hais tau cuam tshuam qhov ntawd. Lawv tsis tau, tawm ntawm qhov tsis paub lossis cia siab tias nws yuav tsis muaj teeb meem. Qhov no yog qhov tseem ceeb ntawm nws: tus nqi txhim khu kev qha qhia txog cov txheej txheem pov thawj. Nws suav rau qhov paub txog qhov teeb meem. Tus nqi pheej yig dua feem ntau tsuas yog hla nws cov ntiv tes.
Qhov kev txiav txim tom qab tuaj rau peb. Peb siv tib lub cuab yeej (uas muaj sia nyob, lwm tus nqi feem ntau tsis nco qab - cuab yeej lub neej). Tus nqi ib feem tau qis dua peb qhov kev tsocai thawj zaug vim tias qhov kev pheej hmoo ploj mus. Peb paub tias cov txheej txheem ua haujlwm. Qhov no yog kev sib raug zoo mus sij hawm ntev uas pob tshab thawj tus nqi tsim. Nws tsis yog hais txog qhov pheej yig tshaj hnub ib; nws yog hais txog qhov raug nqi tshaj lub neej ntawm qhov project.
Machining: Tus khub ntsiag to hauv tus nqi kawg
Qhov no yog qhov tseem ceeb thiab qhov twg ib lub khw sib koom ua ke qhia nws tus nqi. Ib qho as-cam khwb cia yog yuav luag tsis yog qhov kawg. Koj xav tau machining nyiaj pub rau ntawm lub ntsej muag tseem ceeb. Ib tug zoo foundry yuav txo qhov no, tab sis nws yeej ib txwm muaj. Yog tias koj tau txais ib daim ntawv pov thawj los ntawm Foundry A thiab cov lus hais los ntawm Machine Shop B, koj yuav plam ib qho loj ntawm tus nqi puzzle.
Lub foundry yuav tsum to taub qhov twg datum nta yog, qhov twg nruj tolerances yog, yog li ntawd lawv muaj peev xwm muab ib feem ntawm tsob ntoo thiab ntxiv Tshuag raws li. Yog hais tias lawv tsis tswj lub machining, koj yuav raug ib feem uas cam khwb cia zoo nkauj tab sis tsis yooj yim sua kom clamp thiab tshuab yam tsis muaj kev cuam tshuam kev ncaj ncees. Kuv tau pom qhov chaw uas tus nqi machining tripled vim hais tias tus neeg muag khoom casting muab lub rooj vag ntawm qhov yuav tsum yog thawj datum nto. Kev ua haujlwm vertically integrated zoo li QSY zam qhov no. Lawv cov engineers casting thiab CNC programmers sib tham. Cov peev casting nqi lawv muab rau ib tug cam khwb cia thiab tshuab pob yog feem ntau muaj tiag tiag thiab qis dua nyob rau hauv tag nrho ntau tshaj li ntawm ob cais quotes, vim hais tias lawv twb tsim cov txheej txheem saw holistically los ntawm qhov pib.
Lawv kuj tswj cov logistics thiab kev pheej hmoo. Leej twg yog tus lav yog tias pom muaj qhov tawg thaum lub tshuab machining? Yog tias nws yog ib tus neeg muag khoom, cov lus teb yog qhov tseeb. Yog hais tias nws yog ob, nws yog ib tug ntiv tes taw ce uas ncua txhua yam. Qhov kev ncua ntawd muaj tus nqi, ib yam nkaus, txawm hais tias nws yeej tsis tshwm sim ntawm P&L nqe lus kom txog thaum nws lig dhau lawm.
Yog li, Yuav Ua Li Cas Koj Yuav Ntsuas Ib Daim Ntawv Tso Cai?
Tsis txhob saib cov kab hauv qab xwb. Ua kom tawg. Nug txog tus nqi tsim nyog: cov cuab yeej amortization, cov khoom siv nqi ib kg (nrog rau cov nyiaj seem), cov nqi ua, thiab cov nqi kuaj. Ib tus neeg muag khoom muaj npe zoo li QSY, nrog rau keeb kwm ntev, yuav tsis txaj muag ntawm qhov no. Lawv paub tias nws tsim kev ntseeg siab. Yog tias tus neeg muag khoom muab ib pob nyiaj rau koj thiab tsis kam piav qhia, ceev faj.
Cov ntsiab lus yog txhua yam. Puas yog lawv hais raws li koj tus qauv 3D muab, lossis lawv puas tau ua qhov kev tshuaj xyuas kev tsim khoom? Ib qho kev tsocai zoo suav nrog cov lus qhia-Yog tias peb txav qhov rib 2 hli no, peb tuaj yeem zam lub hauv paus thiab txo cov nqi siv los ntawm 30%. Qhov ntawd yog tus khub, tsis yog tus neeg muag khoom xwb. Tus nqi tom qab siv xws li kev tsim-rau-manufacturability hloov yog qhov tseeb, optimized peev casting nqi.
Thaum kawg, xav txog tag nrho cov nqi ntawm cov tswv cuab. suav nrog lub sijhawm ua haujlwm (tus nqi ua haujlwm nrawm dua), qhov zoo sib xws (cov nqi tshuaj xyuas thiab tus nqi tsis ua haujlwm), thiab kev txhawb nqa kev lag luam. Qhov pheej yig tshaj pib nqe lus uas ua rau cov kab ntau lawm yog qhov kev xaiv kim tshaj plaws uas koj tuaj yeem xaiv. Lub hom phiaj yog txhawm rau nrhiav tus nqi uas sawv cev rau cov txheej txheem ruaj khov, rov ua dua, thiab txhim khu kev qha. Qhov ntawd yog tus lej uas tseem ceeb. Tag nrho lwm yam tsuas yog kev cia siab xav.
