Cov hlau 3D luam ntawv puas tuaj yeem txo tus nqi seem hauv pwm tsim?

Ib, Qhov teeb meem pov tseg hauv kev tsim pwm ib txwm: qhov teeb meem ob npaug ntawm cov khoom siv khib nyiab thiab poob kev ua haujlwm
Txoj kev "subtractive processing" yog siv rau hauv kev tsim pwm. Qhov no txhais tau hais tias cov ntaub ntawv maj mam muab tshem tawm los ntawm ntau cov kauj ruam, xws li tig, milling, npaj, thiab sib tsoo, kom txog rau thaum cov duab xav tau. Muaj peb yam teeb meem tseem ceeb ntawm cov txheej txheem no:
Tsawg tus nqi ntawm cov khoom siv: Piv txwv li, thaum ua tuag- casting pwm rau automotive engine lub tog raj kheej taub hau, raug cov txheej txheem yuav tsum tau ua tag nrho cov hlau ingot rau hauv pwm, uas yuav coj mus txog 70% ntawm cov khoom tam sim ntawd. Raws li cov lej los ntawm ib lub tuam txhab, lawv lub rooj cob qhia pwm siv 1200 tonnes ntawm cov hlau hauv ib xyoos. Ntawm qhov ntawd, 840 tonnes tau hloov mus rau hauv cov khib nyiab thiab tsuas yog 360 tonnes tau hloov mus ua cov khoom muaj txiaj ntsig.
Nws yuav siv sij hawm 12 mus rau 15 kauj ruam los ntawm kev npaj cov khoom siv raw kom xa cov khoom kawg. Ua ib txheej pwm tuaj yeem siv li 2 mus rau 3 lub hlis. Lub roj teeb pob pwm kev tsim kho qhov project rau lub tuam txhab tshiab lub zog tsheb tau raug thawb rov qab los ntawm yim lub hlis txij li nws yuav tsum tau rov ua dua ob peb zaug. Qhov no tau ua rau lub tuam txhab raug nqi ntau dua 20 lab yuan.
Cov kev txwv tsis yooj yim: Nws yog ib qho nyuaj rau kev ua pwm nrog cov yam ntxwv nyuaj xws li cov cua txias raws li kev sib tw thiab cov txheej txheem lattice siv cov txheej txheem ib txwm muaj. Txhawm rau ua cov qauv thaiv pwm, ib lub lag luam log tsheb yuav tsum tau tawg tag nrho cov log tsheb rau ntau tshaj 20 ntu thiab ua haujlwm ntawm txhua tus ntawm nws tus kheej ua ntej muab tag nrho ua ke. Qhov no tsis tsuas yog nce tus nqi pov tseg, tab sis nws kuj ua rau cov pwm tsis raug.
2, Kev tawg ntawm hlau 3D luam ntawv: kev hloov pauv ntawm "subtractive" mus rau "additive"
Hlau 3D luam ntawv tsim peb - cov khoom seem los ntawm kev sib tsoo hlau hmoov lossis cov xov hlau nyob rau sab saum toj ntawm ib leeg, uas cuam tshuam tag nrho cov khoom uas feem ntau ua tiav. Nws kuj qhia peb qhov txiaj ntsig tseem ceeb rau kev tswj cov khib nyiab:
1. Kev dhia loj hauv tus nqi ntawm cov khoom siv: los ntawm 30% mus rau 90%
Thaum ua cov txheej txheem nyuaj xws li pwm kab noj hniav thiab cov kav dej txias los ntawm tes, xav tau ntau qhov nyiaj siv ua haujlwm, uas ua rau cov khoom siv khib nyiab ntau heev . 3D tshuab luam ntawv ncaj qha tsav kev tsim khoom siv CAD qauv, thiab nws tsuas yog siv ntau npaum li cov khoom ntawm lawv tus kheej. Siv SLM thev naus laus zis, ib lub tuam txhab tshwj xeeb tau ua aluminium alloy hluav taws xob tsav lub plhaub pwm uas siv 92% ntawm cov khoom siv tsis yog 35% cov qauv siv. Qhov no txuag 180 kilograms ntawm aluminium alloy khoom txhua txheej pwm.
Qhov tseem ceeb tshaj, 3D luam ntawv ua "topology optimisation" tsim tau, uas tuaj yeem siv cov khoom siv tsawg dua thaum tseem muaj zog. Ib lub tuam txhab aviation tau siv topology optimization los ua titanium alloy tis puab pwm uas yog 30% sib dua thiab siv 45% tsawg dua cov khoom thaum tseem ua tau zoo ib yam.
2. Muaj peev xwm ua kom cov txheej txheem nyuaj: tshem tawm cov khoom siv pov tseg
Ib qho kev siv ntau rau 3D luam ntawv los txiav cov khoom pov tseg yog qhov ua kom txias txias, uas yog ib qho nyuaj rau kev ua haujlwm nrog kev siv cov txheej txheem ib txwm muaj. Los ntawm kev tsim cov kauv thiab biomimetic dendritic cua txias raws hauv cov pwm uas haum cov khoom zoo kawg nkaus, qhov ua kom txias tuaj yeem txhawb nqa ntau dua peb zaug. Ib lub tuam txhab ua cov tuag-casting pwm rau lub roj teeb tais ntawm lub zog tshiab. Nws siv 3D luam tawm conformal dej Circuit Court, uas txiav lub voj voog txias los ntawm 45 vib nas this mus rau 18 vib nas this, nce cov khoom tsim nyog tus nqi ntawm 92% mus rau 99.5%, thiab txuag 12 tonnes ntawm steel khib nyiab los ntawm kev txiav cov naj npawb ntawm cov pwm sim.
Lub peev xwm los ua 3D luam ntawv lattice qauv kuj tseem ceeb nyob rau hauv lub cheeb tsam ntawm lub teeb yuag. Ib lub tuam txhab tshwj xeeb tau ua cov pwm txhaj tshuaj rau cov cuab yeej hluav taws xob. Los ntawm kev ua ib tug hollow hexagonal lattice qauv nyob rau hauv lub cheeb tsam uas tsis nqa hnyav, lub pwm qhov hnyav yog txiav los ntawm 25%, tus nqi ntawm cov khoom siv yog txiav los ntawm 30%, thiab lub sij hawm nws coj kom txias yog txiav los ntawm 15% vim hais tias nws muaj peev xwm tuav tau tsawg cua sov.
3. Ceev iteration verification: txiav cov nqi ntawm cov thoob khib nyiab thaum lub sij hawm sim ntau lawm
Txhawm rau ua cov pwm ib txwm muaj, koj yuav tsum mus dhau ntau qhov kev sim ntau lawm kev hloov pauv, thiab txhua qhov kev sim tsim tsim ntau cov khoom pov tseg. Lub tsheb lag luam tau ua haujlwm ntawm lub tshuab dashboard tshiab rau lub tsheb tshiab, tab sis thawj peb qhov kev sim pwm yuav tsum tau muab pov tseg vim yog qhov tsim tsis zoo. Qhov no tsim 45 tonnes pov tseg. Lub voj voog "tsim qauv luam ntawv" tuaj yeem tshwm sim sai nrog 3D tshuab luam ntawv. Tom qab ib lub tuam txhab pib siv cov txheej txheem no, lub voj voog tsim pwm mus los ntawm 6 lub hlis mus rau 6 lub lis piam, tus naj npawb ntawm cov pwm sim mus los ntawm 5 mus rau 2, thiab tus nqi pov tseg tau poob los ntawm 70%.
3, Kev nce qib kev siv tshuab thiab kev koom tes ntawm kev lag luam: kev txhim kho 3D luam ntawv pov tseg.
3D luam ntawv muaj ntau cov lus cog tseg rau kev tswj cov khib nyiab, tab sis nws tseem yuav tsum tau dhau peb qhov teeb meem loj ua ntej nws tuaj yeem siv rau ntawm qhov dav dav:
Cov khoom siv tshiab: Nws yog ib qho tseem ceeb los ua cov khoom siv hmoov tshwj xeeb uas pheej yig thiab ua haujlwm zoo. Ib lub tuam txhab ua cov nano tungsten carbide txhawb H13 steel hmoov uas ua rau cov pwm nyuaj (HRC 60) thaum ua kom nws lub zog. Qhov no txiav cov nqi ntawm cov khoom siv los ntawm 40% piv rau cov khoom tuaj txawv teb chaws.
Txheej txheem txheej txheem: Nws yog ib qho tseem ceeb heev los teeb tsa ib lub tsev qiv ntawv ntawm cov ntawv luam tawm thiab kev tswj xyuas qhov zoo. Ib lub tuam txhab tsim cov txheej txheem kev txhawb nqa automated e-theem rau Hlau +, uas tuaj yeem txo qis ntawm kev siv cov ntaub ntawv txhawb nqa los ntawm 35% thiab nce cov hmoov rov qab mus rau 98%.
Kev sib koom tes hauv kev lag luam: Cov khoom siv, cov khoom siv, thiab cov neeg tsim pwm yuav tsum tau ua haujlwm ua ke los ua kom tiav cov kev daws teeb meem uas suav nrog "khoom siv, khoom siv, thiab kev pabcuam." Ib lub tuam txhab tau tso tawm cov khoom siv UM600MT, uas muaj qhov loj me ntawm 400mm × 600mm × 500mm. Qhov loj me no loj txaus los luam cov tsheb loj loj. Cov txheej txheem database uas txhawb nqa nws muaj ntau dua 200 cov khoom siv uas feem ntau siv.
