Yuav xaiv ib tug 3D hlau luam ntawv tshuab
Apr 29, 2016

Additive manufacturing (AM), los yog printing 3D, rau 21st xyoo pua raug revolutionary gestures ua si rau thawj zaug, thiab txo los ntawm ib lub VOJVOOS es tshem cov khoom siv ntau heev manufacturing txujci, hlau AM nrog ib txheej rau ib txoj kev los ua zaum kawg tej khoom los yog yam khoom nta. Hom stacking no yog tsawg txoj kev raug muaj ntau yam zoo, xws li muaj yooj, khees me ntsis lawm ntawv khoom zaum kawg, kom lub sij hawm rau kev ua lag luam, raug txo nqi, thiab khoom ncua lub neej. Cov zoo tsav AM tshuab yog lug siv nyob rau hauv lub voj txoj sia ntawm qhov khoom, tshiab khoom kev loj hlob, kawg raug, kho qhov khoom.

Siv hlau hmoov AM, tshiab uas yuav pab tau kom zoo dua mus raug txo kev yog yooj yim los yog tsis ncav khoom tawg yooj yim zog thiab ntsuas. Khoom tshiab yuav ua nws ob los sis ntau tshaj cov hmoov tsim muaj alloys tshiab thiab tebchaw uas ua kom tau raws li kev tsim txoj kev sib tw. Thaum lawv tseem hmoov yuav twb tsa tau maj in the process of hloov, los tsim muaj kev faib tawm tej qhov chaw ntawm cov ntaub ntawv, thiab yuav tsum tsis txhob corrosion, nkees, puas thiab ua rau kev nyuaj siab cracking.

Tsis tas li, tshuab AM yuav siv tau rau 3D daim hlau qhov uas muaj ib qho sab hauv, cov tug channel txias piv txwv li. AM txujci kuj yuav manufacture xeem nrog txhua yam khoom zoo heev. Cov Aeronautic Defence nyob sab Europe thiab chaw tuam txhab (EADS) rau ib cov qaug zog to kuaj kev xeem ntsuam xyuas cov khoom Optomec LENS ntawm titanium mus kuaj ntawm 3D mechanism luam ntawv. Txhua yam khoom uas txoj kev kuaj no feem ntau co nyob tib yam li forging EADS thiab qaug zog zog raws li cov qauv aerospace. Ntau cov chaw kuaj cov lwm LENS 3D sau hlau, nrog rau cov hlau stainless thiab Super alloys, xws li npib tsib xee (Inconel).

Kev tshuaj txo manufacturing xws li yuav tau ib ntu ntawm cov kauj ruam thiab cov kab kom peev khoom thiab logistics, thiab AM tib nruam rhais kauj ruam muab lub tivthaiv los yog yam khoom cov yam ntxwv ntawm ontology, yog li tej cov thiab cycle lub sij hawm thiab nqi txuag tau li ib tug lej. Ntxiv thiab, vim AM txoj cai lij choj-d CAD xyaum tsav mus, tsis tas siv cov cuab yeej rau prototyping los yog raug, li ntxiv kom koj tsis txhob cov nqi thiab lub sij hawm rau kev ua lag luam tshiab designs los tsim kho nqi lus. Tsis tas li, AM txoj kev xav kom tau chaw tog hloov cov ntaub ntawv, ces koj yuav tau txo pov tseg. Qhov khoom ntawd rau siv tus nqi siab (piv txwv, titanium thiab Super alloys) uas tseem ceeb heev, vim hais tias txuas xyov tseem ceeb yuav tau siv cov khoom hauv cheeb tsam no.

Aerospace kev lag luam nrog BTF (muas-rau-yoov) tus nqi twb txhais muaj khoom efficiency, nws cov piv embryo thawj rau nyoos wool kom tiav luj ntawm qhov chaw. Raws li paub Heavenly, siv cov tshuaj peb kom txhob raug, aircraft cav makers hais qhov yooj yim 85% rau khoom khib nyiab khoom khib nyiab, thiab txoj kev xeem no txawm 95%, thiaj AM aircraft cav manufacturers tseg cov khoom uas koj yuav siv tau rau cov uas ua tej lub Cheebtsam tus siab. Tej tuam txhab uas muag txawm tias kuv txoj cai lij choj tov nrog txoj kev raug txo thiab raug txoj kev thiaj li yuav ua tau daim ntawv qhia txog siv txog qhov zoo ntawm txhua txoj kev, piv txwv li, lub sij hawm yuav tsum tau siv hlau stainless hauv lub plhaub lawm, kab ke 52 lub limtiam ntawm casting npib hloov mus rau 3 lub lis piam AM txoj cai lij choj.

Kuv kuj siv los mus cuag tus khoom lub neej thiab kho puas lub Cheebtsam, piv txwv li, yog nyob hauv lub teb chaws As Mes Lis Kas Anniston pab tub rog Depot hauv Alabama siv AM tshuab kho cav Cheebtsam ntawm tus Abrams M1 tso tsheb hlau luam, M1 tank xyaw (piv txwv, Honeywell AGT1500) ua hauj lwm hauv ib cheeb tsam suab puam, thiaj yuav muaj cov huab coj, thiab yuav tsum tau muaj ib lub sij hawm luv txij nkawm. Vim distortion los tshwm sim los ntawm kev kub vuam txheej txheem, ua kom yooj yim rau AGT1500 cav Cheebtsam ntawm txoj kev cai, nws yog tus AM txoj kev siv los kho, mas teem laser taws zog thiab hmoov hlau yog xa mus rau qhov chaw kom tau repaired, koj yuav pab txo kom cov cua sov cuam tshuam tsam (kub Affected tsam, HAZ), thiab yuav kho cov cav Cheebtsam.

Thiab kho tej uas turbine cav cheebtsam no feem ntau yog nyuam tsim kua muag thiab coj puas tsuaj rau lub cheeb tsam koojtis (piv txwv, taub) los yog tej thaj chaw uas tsis qaug zog loading (xwsli compressor hniav leading ntug cheeb tsam). Vim tiam sis tsim tivthaiv tsiv mus nyob rau integrated hniav rotor (Integrally-tug-Rotors, IBRs) los yog muaj lub rotor disk (Blisks, los sis hniav/disk), thiaj li yuav txo qhov nyhav thiab zoo cav efficiency, tus kho ntawm tej cheebtsam ua teeb meem loj. Hauv tshuaj disk, yog cov turntable (theem) ntawm tus hniav puas ntsoog los yog hnav, nws tau muab hloov rau tus nqi tsim nyog.
