Koj puas tuaj yeem laser txiav hlau hauv tsev?
Nyob rau hauv xyoo tas los no, qhov muaj koob meej ntawm DIY kev tsim khoom thiab kev cob qhia hauv tsev tau nce siab, nrog ntau tus neeg nyiam tshawb nrhiav cov txheej txheem txiav txiav. Laser txiav, paub txog nws qhov tseeb thiab ntau yam, tau dhau los ua kev nrhiav-tom qab txoj kev ua haujlwm nrog ntau yam ntaub ntawv. Tab sis thaum nws los txog rau hlau - tawv, tshav kub- cov ntaub ntawv resistant- ib lo lus nug tshwm sim: Koj puas tuaj yeem laser txiav hlau hauv tsev? Cov lus teb luv luv yog "nws muaj peev xwm, tab sis tsis ncaj," raws li nws hinges ntawm ntau yam tseem ceeb xws li hom laser, hlau khoom, kev ntsuas kev nyab xeeb, thiab cov nqi khoom siv. Cia peb rhuav tshem cov ntsiab lus los pab koj nkag siab qhov tseeb ntawm tsev hlau laser txiav.
Ua ntej, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm ob lub ntsiab ntawm lasers siv rau kev txiav: CO₂ lasers thiab fiber ntau lasers. Feem ntau nkag- theem tsev laser cutters ntawm kev ua lag luam yog CO₂ lasers, feem ntau ntawm 40W txog 150W. Cov lasers no zoo heev rau kev txiav tsis yog- cov khoom siv hlau xws li ntoo, acrylic, thiab ntawv, tab sis lawv tawm tsam nrog hlau. Vim li cas? Hlau, tshwj xeeb tshaj yog cov hlau zoo li hlau thiab hlau, qhia txog feem ntau ntawm CO₂ laser lub wavelength (10.6 μm). Txawm hais tias lub laser tswj kom nqus tau qee lub zog, lub zog qis ntawm cov neeg nyiam CO₂ lasers tsis txaus los yaj lossis vaporize cov hlau zoo. Cov hlau uas tsis yog-ferrous xws li txhuas thiab tooj liab yog qhov cuam tshuam ntau dua, ua rau lawv yuav luag tsis tuaj yeem txiav nrog CO₂ laser hauv tsev.
Fiber lasers, ntawm qhov tod tes, yog tsim los rau hlau txiav. Lawv ua hauj lwm ntawm ib tug luv luv wavelength (nyob ib ncig ntawm 1.06 μm), uas yog ntau yooj yim absorbed los ntawm feem ntau hlau. Fiber lasers kuj xa ntau zog ceev, cia lawv txiav los ntawm hlau zoo. Nyob rau hauv xyoo tas los no, me me - nplai fiber ntau lasers tau dhau los ua muaj rau kev siv hauv tsev, nrog lub zog ntsuas pib ntawm 50W. 50W fiber ntau laser tuaj yeem txiav cov nplooj nyias nyias ntawm cov hlau me me (txog 1-2 hli), stainless hlau (txog 0.5-1 hli), thiab txhuas (txog 0.3-0.5 hli). Lub zog fiber ntau lasers (100W lossis ntau dua) tuaj yeem ua cov hlau tuab, tab sis lawv kuj tuaj nrog tus nqi siab dua.
Tus nqi yog qhov teeb meem tseem ceeb rau feem ntau cov neeg siv hauv tsev. Nkag mus-theem CO₂ lasers raug nqi ntawm $500 thiab $3,000, tab sis raws li tau hais, lawv tsis haum rau hlau. Fiber lasers, txawm tias cov qauv me tshaj plaws, pib ntawm ib ncig ntawm $ 2,000 thiab tuaj yeem mus txog $ 10,000 lossis ntau dua rau cov khoom siv hluav taws xob ntau dua. Tsis tas li ntawd, koj yuav tsum muaj qhov tseem ceeb ntawm tus nqi ntawm cov khoom siv: lub tshuab hluav taws xob txhim khu kev qha kom tshuab cov hlau molten thiab tiv thaiv oxidation, fume extraction system kom tshem tawm cov pa phem, thiab kev nyab xeeb iav zoo li laser kev nyab xeeb tsom iav ( ntsuas rau qhov tshwj xeeb wavelength ntawm koj lub laser).
Kev nyab xeeb yog lwm yam tsis yog -kev sib tham ntawm lub tsev hlau laser txiav. Laser txiav hlau ua rau kub kub, molten sparks, thiab fumes lom (xws li hlau oxides thiab tej zaum hexavalent chromium yog txiav stainless hlau). Yog tias tsis muaj qhov cua kom raug, cov pa taws no tuaj yeem ua rau muaj kev phom sij loj. Lub laser beam nws tus kheej kuj tseem txaus ntshai - fiber ntau laser beam tsis pom ntawm qhov muag liab qab, yog li kev raug mob tuaj yeem ua rau lub qhov muag puas lossis tawv nqaij kub hnyiab. Koj yuav xav tau ib qho chaw ua haujlwm zoo, zoo- cua tshuab, nyiam dua nrog hluav taws- qhov chaw tiv taus, thiab cov txheej txheem kev nyab xeeb nruj los tiv thaiv kev raug mob.
Kev xaiv cov khoom siv kuj ua lub luag haujlwm tseem ceeb. Tsis yog tag nrho cov hlau sib npaug thaum nws los txog rau laser txiav. Cov hlau me me yog cov hlau yooj yim tshaj plaws los txiav nrog lub tsev fiber ntau laser vim nws qhov qis qis thiab qhov taw tes melting. Stainless hlau yog ib qho nyuaj rau txiav vim nws cov ntsiab lus chromium ntau dua, uas ua rau nws ua rau kub kub. Aluminium thiab tooj liab yog qhov nyuaj dua vim lawv qhov kev xav tau siab, txawm tias fiber ntau lasers. Thickness yog lwm qhov kev txwv: lub tsev fiber ntau lasers tsuas yog siv tau rau nyias cov ntawv hlau- txhua yam tuab dua 2 hli yuav xav tau lub laser muaj zog dua.
Yog tias koj tau teem caij rau kev txiav hlau hauv tsev, ntawm no yog qee cov tswv yim los pib: 1) Kev nqis peev hauv lub tshuab fiber ntau laser (50W lossis siab dua) los ntawm cov chaw tsim khoom muaj koob npe. 2) Pib nrog cov ntawv nyias nyias los xyaum ua koj cov txheej txheem. 3) Xyuas kom koj qhov chaw ua haujlwm zoo -ventilated thiab nruab nrog 5} fume} kev nyab xeeb looj tsom iav thiab hnav ib txwm muaj kev nyab xeeb{ khaub ncaws. 5) Siv lub tshuab cua pab txhawm rau txhim kho kev txiav kom zoo thiab txo cov oxidation.
Rau cov neeg uas tsis xav nqis peev hauv fiber ntau laser, muaj lwm txoj hauv kev rau kev txiav hlau hauv tsev, xws li plasma txiav, txiav waterjet (txawm tias tsawg dua rau kev siv hauv tsev), lossis phau ntawv txoj kev xws li shearing lossis sawing. Plasma txiav feem ntau pheej yig dua li fiber ntau laser txiav thiab tuaj yeem ua cov hlau tuab, tab sis nws tsis tshua meej.
Hauv kev xaus, thaum nws muaj peev xwm laser txiav hlau hauv tsev, nws tsis yog ib qhov project rau cov pib tshiab lossis cov neeg siv nyiaj nruj. Nws yuav tsum muaj fiber ntau laser cutter (tsis yog tus qauv CO₂ laser), qhov chaw ua haujlwm muaj kev nyab xeeb, thiab txaus siab los nqis peev rau hauv cov khoom siv thiab kev nyab xeeb. Yog tias koj feem ntau ua haujlwm nrog cov hlau me me thiab ua qhov tseem ceeb tshaj plaws, lub tsev fiber ntau laser cutter tuaj yeem yog cov cuab yeej tseem ceeb. Txawm li cas los xij, yog tias koj tshiab rau kev ua haujlwm hlau lossis nrhiav kev xaiv pheej yig dua, koj yuav xav tshawb nrhiav lwm txoj kev txiav ua ntej. Raws li nrog txhua qhov project DIY, kev tshawb fawb thiab kev nyab xeeb ua ntej yog qhov tseem ceeb rau kev ua tiav.
