Nyob rau hauv daim ntawv thov Moulds, Signs, Hardware Accessories, Billboards, Tsheb daim ntawv tso cai daim hlau thiab lwm yam khoom, tsoos corrosion txheej txheem yuav tsis tsuas ua rau ib puag ncig muaj kuab paug, tab sis kuj tsis tshua muaj efficiency.Cov txheej txheem ib txwm siv xws li machining, hlau seem thiab coolants tuaj yeem ua rau muaj kuab paug ib puag ncig.Txawm hais tias qhov kev ua tau zoo tau raug txhim kho, qhov tseeb tsis yog siab, thiab cov kaum ntse ntse tsis tuaj yeem carved.Piv nrog rau cov tsoos hlau sib sib zog nqus carving txoj kev, laser hlau sib sib zog nqus carving muaj qhov zoo ntawm cov pa phem, siab precision, thiab saj zawg zog carving ntsiab lus, uas yuav ua tau raws li qhov yuav tsum tau ntawm complex carving txheej txheem.
Cov ntaub ntawv zoo sib xws rau hlau sib sib zog nqus carving muaj xws li carbon steel, stainless hlau, txhuas, tooj liab, precious hlau, thiab lwm yam. Engineers ua high-efficiency sib sib zog nqus carving parameter kev tshawb fawb rau cov khoom hlau sib txawv.
Kev txheeb xyuas qhov tseeb:
Test platform khoom Carmanhaas 3D Galvo Lub Taub Hau nrog Lens (F = 163/210) ua qhov kev sib sib zog nqus carving.Engraving loj yog 10 mm × 10 mm.Teem thawj qhov tsis sib xws ntawm engraving, raws li pom nyob rau hauv Table 1. Hloov cov txheej txheem tsis xws li tus nqi ntawm defocus, mem tes dav, ceev, filling interval, thiab lwm yam., siv lub sib sib zog nqus carving tester ntsuas qhov tob, thiab nrhiav cov txheej txheem tsis. nrog rau qhov zoo tshaj plaws carving nyhuv.
Table 1 Initial parameters of deep carving
Los ntawm cov txheej txheem parameter cov lus, peb tuaj yeem pom tias muaj ntau yam tsis muaj kev cuam tshuam rau qhov kawg engraving nyhuv.Peb siv txoj kev tswj hwm qhov sib txawv kom pom cov txheej txheem ntawm txhua tus txheej txheem parameter qhov cuam tshuam ntawm cov nyhuv, thiab tam sim no peb yuav tshaj tawm lawv ib qho los ntawm ib qho.
01 Cov nyhuv ntawm defocus ntawm carving qhov tob
Ua ntej siv Raycus Fiber Laser Source, Fais fab: 100W, Qauv: RFL-100M los kos cov cim thawj zaug.Ua qhov kev xeem engraving ntawm cov hlau sib txawv.Rov ua qhov engraving 100 zaug rau 305 s.Hloov lub defocus thiab sim cov nyhuv ntawm defocus ntawm cov nyhuv engraving ntawm cov khoom sib txawv.
Daim duab 1 Kev sib piv ntawm cov nyhuv ntawm defocus ntawm qhov tob ntawm cov khoom carving
Raws li pom nyob rau hauv daim duab 1, peb tuaj yeem tau txais cov hauv qab no txog qhov tob tshaj plaws uas sib txawv ntawm cov defocusing sib txawv thaum siv RFL-100M rau kev sib sib zog nqus engraving hauv cov ntaub ntawv hlau sib txawv.Los ntawm cov ntaub ntawv saum toj no, nws tau txiav txim siab tias kev sib sib zog nqus carving ntawm cov hlau nto yuav tsum muaj qee yam defocus kom tau txais txiaj ntsig zoo tshaj plaws engraving.Lub defocus rau engraving txhuas thiab tooj dag yog -3 hli, thiab lub defocus rau engraving stainless hlau thiab carbon hlau yog -2 hli.
02 Cov nyhuv ntawm mem tes dav ntawm carving qhov tob
Los ntawm cov kev sim saum toj no, qhov zoo tshaj plaws defocus tus nqi ntawm RFL-100M hauv kev sib sib zog nqus engraving nrog cov ntaub ntawv sib txawv tau txais.Siv qhov zoo tshaj plaws defocus tus nqi, hloov lub mem tes dav thiab sib thooj zaus nyob rau hauv thawj tsis, thiab lwm yam tsis hloov.
Qhov no feem ntau yog vim hais tias txhua tus mem tes dav ntawm RFL-100M laser muaj qhov sib npaug ntawm qhov tseem ceeb.Thaum qhov zaus qis dua qhov sib thooj ntawm cov zaus, cov zis hluav taws xob qis dua qhov nruab nrab lub zog, thiab thaum qhov zaus siab dua li qhov sib thooj, lub zog siab yuav txo qis.Kev xeem engraving yuav tsum tau siv qhov loj tshaj plaws mem tes dav thiab lub peev xwm siab tshaj plaws rau kev sim, yog li qhov kev xeem zaus yog qhov tseem ceeb, thiab cov ntaub ntawv xeem uas cuam tshuam yuav tau piav qhia hauv qab no.
Qhov tseem ceeb zaus sib xws rau txhua tus mem tes dav yog: 240 ns, 10 kHz, 160 ns, 105 kHz, 130 ns, 119 kHz, 100 ns, 144 kHz, 58 ns, 179 kHz, 40 ns, 245 kHz, 90 kHz, 10 ns, 999 kHz.Ua qhov kev xeem engraving los ntawm cov mem tes saum toj no thiab zaus, qhov kev ntsuam xyuas tau pom hauv daim duab 2
Daim duab 2 Kev sib piv ntawm cov nyhuv ntawm pulse dav ntawm engraving qhov tob
Nws tuaj yeem pom los ntawm daim ntawv qhia tias thaum RFL-100M yog engraving, raws li qhov dav ntawm mem tes txo, qhov engraving qhov tob zuj zus raws li.Qhov engraving qhov tob ntawm txhua yam khoom yog qhov loj tshaj plaws ntawm 240 ns.Qhov no feem ntau yog vim qhov txo qis ntawm tib lub zog pulse vim qhov txo qis ntawm cov mem tes dav, uas nyob rau hauv lem txo qhov kev puas tsuaj rau saum npoo ntawm cov khoom hlau, uas ua rau lub engraving qhov tob ua me thiab me.
03 Kev cuam tshuam ntawm zaus ntawm engraving qhov tob
Los ntawm cov kev sim saum toj no, qhov zoo tshaj plaws defocus tus nqi thiab mem tes dav ntawm RFL-100M thaum engraving nrog cov ntaub ntawv sib txawv tau txais.Siv qhov zoo tshaj plaws defocus tus nqi thiab mem tes dav kom nyob twj ywm tsis hloov, hloov qhov zaus, thiab sim cov nyhuv ntawm ntau zaus ntawm qhov tob engraving.Cov txiaj ntsig kev xeem Raws li pom hauv daim duab 3.
Daim duab 3 Kev sib piv ntawm kev cuam tshuam ntawm zaus ntawm cov khoom sib sib zog nqus carving
Nws tuaj yeem pom los ntawm daim ntawv qhia tias thaum RFL-100M laser yog engraving ntau yam ntaub ntawv, raws li qhov zaus nce, qhov engraving qhov tob ntawm txhua yam khoom txo qis raws li.Thaum qhov zaus yog 100 kHz, qhov engraving qhov tob yog qhov loj tshaj plaws, thiab qhov siab tshaj plaws engraving qhov tob ntawm txhuas ntshiab yog 2.43.mm, 0.95 hli rau tooj dag, 0.55 hli rau stainless hlau, thiab 0.36 hli rau carbon steel.Ntawm lawv, aluminium yog qhov nkag siab tshaj plaws rau kev hloov pauv zaus.Thaum qhov zaus yog 600 kHz, sib sib zog nqus engraving tsis tuaj yeem ua rau ntawm qhov chaw ntawm txhuas.Txawm hais tias tooj dag, stainless hlau thiab carbon hlau tsis tshua muaj kev cuam tshuam los ntawm zaus, lawv kuj qhia txog kev txo qis engraving qhov tob nrog ntau zaus.
04 Kev cuam tshuam ntawm kev nrawm ntawm kev kos qhov tob
Daim duab 4 Kev sib piv ntawm cov nyhuv ntawm carving ceev ntawm carving qhov tob
Nws tuaj yeem pom los ntawm daim ntawv qhia tias thaum engraving ceev nce, qhov engraving qhov tob yuav txo qis raws li.Thaum engraving ceev yog 500 mm / s, engraving qhov tob ntawm txhua yam khoom yog qhov loj tshaj plaws.Lub engraving qhov tob ntawm txhuas, tooj liab, stainless hlau thiab carbon hlau yog feem ntau: 3.4 hli, 3.24 hli, 1.69 hli, 1.31 hli.
05 Cov nyhuv ntawm qhov sib txawv ntawm qhov tob engraving
Daim duab 5 Cov txiaj ntsig ntawm kev sau ntom ntom ntawm kev ua haujlwm engraving
Nws tuaj yeem pom los ntawm daim ntawv qhia tias thaum qhov ntim qhov ntom ntom yog 0.01 hli, qhov tob tob ntawm txhuas, tooj dag, stainless hlau, thiab carbon hlau yog tag nrho cov siab tshaj plaws, thiab cov engraving qhov tob yuav txo qis raws li qhov sib txawv ntawm qhov filling nce;qhov sib txuas ntxiv ntawm 0.01 hli Nyob rau hauv tus txheej txheem ntawm 0.1 hli, lub sij hawm yuav tsum tau ua kom tiav 100 engravings yog maj shortened.Thaum qhov kev ncua deb ntau dua 0.04 hli, lub sij hawm luv luv yog txo qis.
Nyob rau hauv xaus
Los ntawm cov kev ntsuam xyuas saum toj no, peb tuaj yeem tau txais cov txheej txheem pom zoo rau kev sib sib zog nqus ntawm cov khoom siv hlau sib txawv siv RFL-100M:
