Cov tshuab vuam laser hlau uas peb lub tuam txhab tsim thiab tsim tawm siv cov qhov uas ua los ntawm cov av nplaum uas tsis yooj yim xeb, tiv taus kub heev, thiab muaj kev hloov pauv hluav taws xob zoo heev. Lub qhov uas ua kom pom tseeb thiab lub teeb xenon muaj lub neej ua haujlwm ntau dua 8 lab lub voj voog. Cov roj tiv thaiv ua rau cov vuam zoo nkauj yam tsis muaj oxidation lossis xim ploj. Lub tshuab no ua haujlwm tau 24/7 nrog kev ua haujlwm ruaj khov.

Qhov zoo ntawm kev siv laser welding yog tias nws siv tau rau hauv cov lag luam xws li cov hniav nyiaj hniav kub, roj teeb, thiab cov khoom siv xov tooj ntawm tes.

Kev vuam laser yog tus cwj pwm los ntawm lub zog vuam siab, ceev ceev, thiab cov nqi pov tseg tsawg, ua rau nws siv dav hauv kev tsim khoom niaj hnub. Hauv kev tsim cov hniav nyiaj hniav kub, nws muaj cov txiaj ntsig sib txawv dua li cov txheej txheem vuam ib txwm muaj:

1. Ceev ceev, Muaj zog heev, Tsawg tshaj qhov hloov pauv, Tsis muaj kev ncaj lossis ntxuav tom qab vuam Qhov laj thawj tseem ceeb uas cov tuam txhab tsim khoom siv laser vuam yog nws qhov ceev ceev thiab tsawg tshaj qhov hloov pauv, tshem tawm qhov xav tau kev ncaj thiab ntxuav tom qab vuam. Thaum laser vuam sai dua li cov nplaim taws vuam ib txwm muaj, cov neeg ua haujlwm feem ntau tuav cov khoom ua haujlwm los ntawm tes lossis siv cov khoom siv, vuam ib daim ib zaug. Feem ntau cov chaw ua haujlwm vuam laser hniav nyiaj hniav kub yog compact, txwv tsis pub muaj peev xwm ua tiav ntau thiab ua rau lub sijhawm vuam nce me ntsis. Txawm li cas los xij, lub sijhawm txuag ntawm kev ntxuav them rau qhov no tag nrho. Laser vuam tuaj yeem ua tiav hauv qab kev tiv thaiv roj inert, tsis muaj cov xim hluav taws rau cov khoom - tshem tawm qhov xav tau flux thaum vuam thiab acid pickling tom qab. Zuag qhia tag nrho, laser vuam muab kev ua haujlwm ntau dua.

2. Haum rau cov khoom ua haujlwm precision, xyuas kom meej tias zoo sib xws

Lub teeb laser tuaj yeem tsom mus rau hauv ib qho chaw me me rau qhov chaw meej, ua rau nws zoo tagnrho rau kev tsim khoom loj. Nws tsis tsuas yog txhim kho kev ua haujlwm zoo xwb tab sis kuj txo qhov chaw kub hnyiab thiab ua kom tsis muaj kuab paug, txhim kho qhov zoo ntawm kev vuam thiab txo cov nqi pov tseg. Piv txwv li, 14K alloy hniav nyiaj hniav kub (58% Au, 2% Ag) vuam los ntawm nplaim taws vuam yuav ntsib Ag annealing, txo qhov nyuaj tag nrho los ntawm Hv = 145 los ntawm kwv yees li ib nrab - ua rau muaj qhov dents yog tias poob ntawm qhov siab ntawm lub duav. Qhov sib piv, qis-zog, high-speed laser vuam ua rau kub, tiv thaiv workpiece annealing thiab khaws cia lub zog ntawm cov qauv.

3. Kev Sib Dhos Zoo, Pab Kom Muaj Cov Txheej Txheem Tsim Khoom Siv Hniav Nyiaj Hniav Kub Tshiab Kev qhia txog kev vuam laser hauv kev lag luam hniav nyiaj hniav kub tau hloov pauv kev xav tsim qauv ib txwm muaj. Nws ua rau muaj kev tsim cov qauv hniav nyiaj hniav kub tshwj xeeb uas yav dhau los nyuaj rau ua tiav lossis ua tsis tau raws li qhov yuav tsum tau ua zoo nrog kev vuam ib txwm muaj. Kev vuam laser ua haujlwm hauv thaj chaw nqaim, pab txhawb kev vuam ntawm cov khoom sib xyaw sib txawv yam tsis muaj kev sib xyaw - tso cai rau xim sai lossis kev hloov pauv ntawm cov khoom. Nws thaj chaw ua haujlwm nqaim sib txawv nws ntawm kev vuam ib txwm muaj nyob rau hauv cov nqe lus ntawm kev ntub dej, kev sib koom ua ke, thiab qhov loj ntawm cov noob hauv thaj chaw cuam tshuam los ntawm cua sov.

4. Kev Sib Thooj Zoo thiab Kev Ruaj Ntseg

Laser welding feem ntau ua tiav kev vuam ncaj qha los ntawm kev yaj cov khoom ua haujlwm hauv zos yam tsis tas yuav siv cov hlau sau lossis cov dej ntws.

5. Ua kom yooj yim kho cov khoom ua haujlwm

Nws tuaj yeem kho cov hlau ze ntawm cov pob zeb diamond, tshem tawm cov qhov hauv cov castings, thiab vuam cov chaw ze li 0.2 hli rau cov khoom nyuaj, cov khoom rhiab heev rau cua sov (piv txwv li, hinges, hooks, clasps, thiab chaw teeb tsa).

6. Ib puag ncig zoo

Tsis tas yuav siv cov tshuaj solder, flux, lossis cov tshuaj ntxuav tshuaj thaum lub sijhawm laser welding, tshem tawm cov teeb meem pov tseg.

7. Txuag Cov Khoom Siv Hlau

Kev vuam ib txwm xav tau qhov tuab hlau tsawg kawg nkaus ntawm 0.2 hli, thaum kev vuam laser txo qhov no mus rau 0.1 hli - txo qhov hnyav ntawm cov hniav nyiaj hniav kub los ntawm 35% ~ 40%, uas yog qhov tseem ceeb tshwj xeeb rau cov khoom electroformed. Kev vuam laser txuag cov hlau muaj nqis thiab cov solder, thiab tshem tawm qhov xav tau ntau hom solder hauv ntau qhov kev vuam.

8. Cov yam ntxwv ntawm lub tshuab tseem ceeb

Cov tshuab laser vuam hniav nyiaj hniav kub uas feem ntau siv hauv kev lag luam muaj zog tsawg, ua kom muaj kev nyab xeeb siab. Lawv muaj lub qauv me me, yooj yim nqa tau, ua rau cov neeg teb xov tooj ua haujlwm tau yooj yim thaum zaum.
Cov tshuab laser vuam hniav nyiaj hniav kub ib txwm muajtuaj yeem vuam feem ntau cov hlau thiab cov hlau sib xyaw sai, txhim khu kev qha, thiab raug, txawm hais tias qhov ua tau zoo feem ntau nyob ntawm cov khoom siv lub hom phiaj. Kev sib dhos lossis kev kho kho tas mus li tuaj yeem ua tiav nrog ib lossis ntau lub laser pulses nyob rau hauv kev tswj hwm pom, nrog txhua lub pulse kav ntev li 1 ~ 20ms. Stereomicroscopes thiab crosshair alignment ua rau muaj qhov chaw vuam meej, tso cai rau kev hloov kho zoo ntawm qhov chaw ua haujlwm hauv thaj chaw pom. Kev vuam feem ntau yog ua nyob rau hauv cov huab cua; txhaj cua lossis roj inert rau hauv thaj chaw ua haujlwm tuaj yeem ua rau txias, thiab roj inert ntxiv txhim kho qhov zoo ntawm kev vuam hlau.

9. Kev cuam tshuam ntawm Cov Khoom Siv Alloy rau Kev Ua Haujlwm Laser Welding
Cov khoom siv sib txawv sib txawv ua rau muaj qhov sib txawv ntawm kev vuam laser. Nyob rau hauv tib lub tshuab parameter thiab pulse cua sov nkag, qhov sib txawv ntawm qhov sib piv ntawm lub zog thermal nqus (vs. cuam tshuam) los ntawm qhov chaw alloy ua rau muaj qhov sib txawv ntawm cov teebmeem yaj ib pulse. Cov yam tseem ceeb uas cuam tshuam suav nrog lub peev xwm cua sov (los ntawm qhov kub hauv chav mus rau qhov melting point), melting point, latent cua sov ntawm fusion, thiab thermal conductivity. Kev hloov pauv ntawm cov khoom no thoob plaws cov ntaub ntawv cuam tshuam rau lub zog xav tau rau kev vuam zoo - kev nqus cua sov txaus ntawm qhov chaw yog qhov tseem ceeb rau kev vuam zoo.
