Kev soj ntsuam ntawm Daim Ntawv Thov Kev Ua Haujlwm thiab Kev Txhim Kho Kev Txhim Kho ntawm Kev Siv Tshuab Zoo Tshaj Plaws hauv Kev Ua Haujlwm ntawm Cov Tsheb Hluav Taws Xob Tshiab

 

Nyob rau hauv xyoo tas los no, nrog rau kev nce qib thiab kev loj hlob ntawm lub zog tshiab thev naus laus zis, kev tsim cov khoom siv hluav taws xob tshiab kuj tau txhim kho. Raws li ib feem tseem ceeb ntawm lub tsheb tsim kev lag luam, lub zog tshiab tsheb tsim kev lag luam tsis txaus siab rau ib txwm muajvuamtechnology tab sis tau hloov nws nrog cov thev naus laus zis tshiab. Txog qhov kawg, daim ntawv no tshuaj xyuas cov ntawv thov ntawm cov cuab yeej siv vuam zoo xws li do txhuam vuam, txias hlau hloov vuam, thiablaser vuamnyob rau hauv lub zog tshiab tsheb kev lag luam, thiab tos ntsoov rau txoj kev loj hlob ntawm vuam tshuab nyob rau hauv lub tshiab zog tsheb kev lag luam.

 

 

 

 

 

Piv nrog cov tsheb siv roj, cov tsheb tshiab muaj kev nyab xeeb dua, kev siv hluav taws xob zoo, thiab kev tiv thaiv ib puag ncig. Lawv cov khoom tsim muaj ntau yam khoom siv thiab cov qauv, nrog rau cov khoom siv hnyav xws li aluminium alloy, carbon fiber, fiberglass, thiab ntau yam khoom siv hluav taws xob. Hauv kev tsim thiab tsim cov txheej txheem tshiab ntawm lub zog tsheb, vuam tshuab yog qhov txuas tseem ceeb.

 

Vuam, tseem hu ua fusion, yog hais txog kev ua cov thev naus laus zis ntawm atomic bonding ntawm cov hlau los yog cov hlau tsis muaj hlau lossis cov hlau thiab cov hlau tsis yog hlau los ntawm cua kub pressurizing, los yog ob qho tib si. Raws li qhov txuas tseem ceeb hauv kev tsim cov tsheb tshiab lub zog, xaiv cov txheej txheem vuam tsim nyog yog qhov tseem ceeb rau kev tsim cov tsheb tshiab.

 

Ua ke nrog cov qauv dav dav ntawm dataization, automation, thiab kev koom ua ke ntawm niaj hnub kev tshawb fawb thiab thev naus laus zis, ntau yam tshiab vuam thev naus laus zis tau tshwm sim thiab tau siv, uas tau txhim kho qib vuam zoo heev thiab ua rau muaj txiaj ntsig zoo dua.cov khoom siv vuamua tau. Tam sim no, cov thev naus laus zis tshiab xws li kev hloov pauv hlau txias thiab laser vuam siv hauv tsev thiab txawv teb chaws tau txhawb txoj kev vam meej sai ntawm kev lag luam tsheb tshiab.

 

 

Laser welding tshuab yog ib txoj kev siv hluav taws xob hluav taws xob siab. Nws qhov chaw tshav kub yog lub teeb laser nrog lub zog siab ceev. Raws li ib tug high-zog-density electromagnetic yoj, ib tug laser muaj cov yam ntxwv ntawm high focusing, siab ncaj, thiab siab controllability. Nyob rau hauv cov txheej txheem laser vuam, lub zog laser yog thawj zaug tsom rau ntawm qhov chaw vuam ntawm qhov chaw ntawm lub workpiece, thiab qhov chaw ntawm lub workpiece yog rhuab mus rau lub melting point los yog vaporization point los tsim ib tug molten pas dej ua ke.

 

Tom qab ntawd, lub workpiece yuav tsum tau welded yog raws li nyob rau hauv vuam txoj hauj lwm, thiab ob workpiece molten pas dej ua ke yog fused nyob rau hauv tsim nyog siab thiab tiv thaiv roj. Vim tias nws lub laser muaj kev ywj pheej loj hauv cov khoom siv, cov duab, qhov loj me, thiab qhov chaw ua haujlwm ntawm cov khoom ua tiav.

 

Lub spatial controllability thiab lub sij hawm controllability ntawm lub laser yog yooj yim los tswj, ua rau nws haum rau automated lag luam. Ntxiv mus, raws li lub zog siab ceev thiab siab ua kom pom tseeb ntawm lub laser, laser vuam tuaj yeem ua tiav kev kub ceev, siab precision, thiab zoo vuam cuam tshuam. Tam sim no, laser vuam tshuab tau txais kev saib xyuas zoo thoob plaws ntiaj teb. Cov tuam txhab suav tsis txheeb thiab cov tuam txhab tau nqis peev hauv kev tshawb fawb txog kev sib raug zoo, thiab qib kev txawj ntse tau tsim sai heev.

 

 

 

 

Additive manufacturing technology yog ib lub tshuab uas siv high-zog laser beams yaj hlau hmoov los ua complex structural hlau qhov chaw. Nws muab faib ua laser xaiv melting (SLM) thiab laser direct deposition. Laser xaiv melting yog raws li lub hauv paus ntsiab lus ntawm txheej txheej superposition manufacturing, siv high-zog laser beams yaj hlau hmoov txheej los ntawm txheej los tsim complex structural hlau qhov chaw.

 

Raws li cov ntaub ntawv 3D uas twb muaj lawm ntawm ib feem, txoj kev scanning yog tsim. Cov cuab yeej tswj hwm lub laser beam kom xaiv yaj txhua txheej ntawm cov hmoov hlau hlau raws li txoj kev scanning thiab maj mam muab tso rau hauv ib feem peb-dimensional. Laser ncaj qha deposition yog ib tug laser uas tua downwards los ntawm sab saum toj ntawm lub weld sib koom ua ke raws lub axis kev taw qhia, nyob ze ntawm cov hmoov tsom xam point, thiab melts lub synchronously emitted hmoov.

 

Nyob rau tib lub sijhawm, qhov sib koom ua ke txav mus raws li kev soj ntsuam trajectory ntawm txhua txheej ntawm ib feem, thiab cov kua hlau molten ua tiav cov txheej txheem ntawm cov khoom raws li cov matrix lossis cov txheej txheem yav dhau los. Lub khoos phis tawj txuas ntxiv hu rau hauv cov txheej txheem txuas ntxiv ntawm cov duab kos duab, rov ua cov haujlwm saum toj no, kom nws yog txheej txheej los ntawm txheej, thiab thaum kawg, ib feem hlau nrog ua tiav metallurgical bonding yog tsim.

 

 

Raws li kev lag luam tsim tawm tshiab, lub zog tshiab tsheb kev lag luam tau siv dav siv thev naus laus zis ntawm kev tsim khoom hauv tsev hauv kev ua thiab kev tsim khoom. Vuam yog yuav tsum tau raws li cov txheej txheem kev sib txuas hauv ntau qhov chaw xws li roj teeb, lub cev tsheb, lub cev muaj zog, thiab lwm yam. Yog li ntawd, rau lub zog tshiab lub tsheb kev lag luam kom muaj txiaj ntsig zoo dua thiab cov khoom lag luam zoo dua, cov cuab yeej siv vuam siab heev yog irreplaceable.

 

 

Yog tias koj txaus siab rau peb cov khoom lag luam laser vuam, thov nyem qhov txuas hauv qab no kom paub ntau ntxiv:
