Dab tsi yog qhov txawv ntawm Laser Txiav Tshuab?

Laser Txiavyog kev siv lub teeb pom kev zoo siab ceev laser beam kom irradiate lub workpiece, kom cov khoom irradiated sai sai melts, vaporize, ablates, s los yog ncav cuag lub ignition point, thiab nyob rau tib lub sij hawm nrog lub beam coaxial high-speed airflows. tawm ntawm cov khoom siv molten, thiaj li ua tiav lub workpiece txiav. Laser txiav yog ib qho ntawm cov txheej txheem thermal txiav.

Laser txiav tuaj yeem muab faib ua plaub pawg: laser vaporization txiav, laser melting txiav, laser oxygen txiav, thiab laser scribing thiab tswj puas.

1. Laser vaporization txiav

Siv lub laser beam nrog lub zog siab ceev kom sov lub workpiece, qhov kub thiab txias nce mus txog qhov kub ntawm cov khoom nyob rau hauv ib lub sij hawm luv luv, thiab cov khoom pib vaporize thiab tsim chav. Qhov ceev ntawm cov vapors yog siab heev, thiab tib lub sij hawm lub vapor yog emission, ib tug notch yog tsim nyob rau hauv cov khoom. Lub tshav kub ntawm vaporization ntawm cov khoom yog feem ntau loj, yog li lub laser vaporization txiav yuav tsum muaj lub zog loj thiab lub zog ceev.

Laser vaporization txiav feem ntau yog siv los txiav cov ntaub ntawv nyias nyias thiab cov khoom tsis yog xim hlau (xws li ntawv, ntaub, ntoo, yas thiab roj hmab, thiab lwm yam.)

2. Laser fusion txiav

Thaum laser melting txiav, cov khoom siv hlau yog melted los ntawm laser cua sov, thiab tom qab ntawd tsis-oxidizing roj (Ar, Nws, N, thiab lwm yam) yog txau los ntawm lub nozzle coaxial nrog beam, thiab cov kua hlau yog tawm los ntawm lub zog siab. ntawm cov pa los tsim cov incision. Laser melting txiav tsis xav kom cov hlau ua kom vaporized, thiab lub zog xav tau tsuas yog 1/10 ntawm vaporized txiav.

Laser melting txiav yog tsuas yog siv rau kev txiav ntawm qee cov ntaub ntawv tsis-oxidizing lossis cov hlau nquag, xws li stainless hlau, titanium, aluminium thiab nws cov alloys.

3. Laser oxygen txiav

Lub hauv paus ntsiab lus ntawm laser oxygen txiav yog zoo ib yam li oxy-acetylene txiav. Nws siv lub laser ua qhov cua sov preheating thiab cov pa roj xws li oxygen ua cov roj txiav. Ntawm qhov tod tes, cov pa cua tshuab tawm cuam tshuam nrog cov hlau txiav kom dhau los ua cov tshuaj tiv thaiv oxidation thiab tso tawm ntau qhov kub ntawm oxidation; Ntawm qhov tod tes, cov molten oxide thiab yaj yog cua tshuab tawm ntawm thaj chaw tshuaj tiv thaiv, tsim ib qho kev txiav hauv cov hlau. Cov tshuaj tiv thaiv oxidation hauv cov txheej txheem txiav ua kom muaj cua sov ntau, yog li lub zog xav tau rau laser oxygen txiav tsuas yog 1/2 ntawm cov melting txiav, thiab txiav ceev yog ntau dua li laser vaporization txiav thiab melting txiav.

Laser pa oxygen txiav yog tsuas yog siv rau cov pa roj carbon steel, titanium hlau thiab kub-kho hlau, thiab lwm yam yooj yim oxidized hlau cov ntaub ntawv.

4. Laser scribing thiab tswj kev puas tsuaj

Laser scribing yog siv lub zog siab ceev laser scan rau ntawm qhov chaw ntawm cov khoom siv nkig kom cov khoom siv kom sov kom evaporate tawm ntawm qhov me me, thiab tom qab ntawd siv qee qhov siab, cov khoom siv nkig yuav raug faib raws qhov me me. Cov lasers siv rau laser scribing feem ntau yog Q-hloov lasers thiab CO2 lasers.

Kev tswj cov pob txha yog kev siv cov khoom sib sib zog nqus uas tsim los ntawm laser grooving los tsim cov thermal kev nyuaj siab hauv zos hauv cov khoom tawg, ua rau cov khoom tawg raws cov grooves me.

Thaum siv laser txiav, koj yuav tsum nkag siab cov yam ntxwv ntawm txhua yam khoom thiab ua tib zoo saib xyuas nws thaum siv tiag tiag.

Cov ntaub ntawv uas tuaj yeem txiav los ntawm laser txiav:

1. Cov hlau sib txawv

Laser txiav tshuab tuaj yeem txiav txhua hom hlau los ntawm cov hlau me me thiab stainless hlau mus rau cov hlau tsis muaj hlau. Reflective hlau xws li txhuas yog qhov nyuaj rau txiav, lub sijhawm no, fiber ntau lasers yog qhov kev xaiv zoo dua. Niaj hnub no, kev txiav thickness ntawm cov hlau tuaj yeem ncav cuag 100 hli, thiab cov thickness txiav txawv raws li lub zog ntawm laser.

2. Ntoo

Txhua hom ntoo (xws li plywood thiab MDF) tuaj yeem txiav nrog lasers, tab sis qee cov ntoo oily ua rau muaj kev pheej hmoo ntawm igniting thiab yuav tsum tau siv nrog kev saib xyuas tshwj xeeb.

3. Ntawv thiab duab los qhia

Daim ntawv kuj tsim nyog rau laser txiav, peb pom ib co complex thiab exquisite kab tshoob caw, uas yuav ua tau los ntawm laser txiav.

4. Cov khoom siv yas

Acrylic, PMMA, thiab Lucite yog cov yas pob tshab. Thaum siv laser txiav, ntug tuaj yeem lav tau kom muaj qhov ua tiav zoo, thiab nws zoo li cov nplaum txiav nrog rab riam.

5. Polyformaldehyde

Polyformaldehyde yog cov yas siv tau zoo heev hauv kev ua haujlwm engineering thiab tuaj yeem siv rau hauv lub zog, kev taw qhia thiab zawv zawg Cheebtsam, cov khoom siv kho mob, ntim khoom noj, thiab lwm yam. Lub peev xwm siv lasers rau txoj kev txiav tau ua rau kev siv dav ntawm polyformaldehyde hauv ntau qhov chaw.

6. iav

Vim nws cov khoom tawg yooj yim thiab muaj kev cuam tshuam, laser txiav iav yuav zoo li ua haujlwm tsis yooj yim. Txawm li cas los xij, laser cutters tuaj yeem txiav iav.

Nws yuav zoo li lub laser tuaj yeem txiav yuav luag txhua yam, tab sis nws tsis yog, thiab feem ntau ntawm cov ntaub ntawv ntawm "tsis tuaj yeem txiav" cov npe yog ntau yam yas.

Cov ntaub ntawv uas tsis tuaj yeem txiav los ntawm laser txiav:

1. Polyvinyl chloride

Txiav PVC yuav tawm cov kua qaub thiab cov pa phem, uas ua rau muaj kev phom sij rau tus neeg teb xov tooj ntawm lub tshuab thiab lub tshuab laser txiav nws tus kheej, yog li PVC txiav tseem tshuav rau cov txheej txheem ua kom tiav.

2. Polycarbonate fiber ntau

Polycarbonate me dua 1 hli tuaj yeem sim nrog lub laser cutter tab sis yuav ua rau cov khoom tsis zoo.

Yog tias cov khoom siv tuab, tsis muaj txoj hauv kev los siv laser txiav, tsis tsuas yog siv tsis tau, tab sis cov khoom yog faded, tab sis kuj yuav ua rau combustion.

3. ABS, high-density polyethylene

Feem ntau, qhov kub ntawm lub laser beam yog txaus rau vaporize cov khoom, tab sis nws tsis txhawb cov ntaub ntawv xws li ABS thiab high-density polyethylene. Lawv nyiam yaj ntau dua li vaporize, tawm hauv cov ntxhuav tsis zoo thiab tsis zoo txiav.

4. Polystyrene thiab polypropylene ua npuas ncauj

Ob leeg ntes hluav taws yooj yim.

5. Fiberglass

Fiberglass yog sib xyaw ntawm ob cov ntaub ntawv - iav thiab epoxy resin. Txiav iav ib leeg yog qhov nyuaj heev, thiab ntxiv cov pa luam yeeb ua rau cov khoom sib xyaw ua ke yuav yog npau suav phem.
