Puas Muaj Lub Hom Phiaj Tshuaj Rau Qhov Deformation ntawm Lub Roj Teeb Pob Plhaub Thaum Vuam?

Lub roj teeb ntim ntim, ua haujlwm tseem ceeb ntawm kev tiv thaiv, feem ntau yog ua los ntawm cov ntaub ntawv nyias nyias xws li aluminium alloy thiab 304 stainless hlau (nrog tuab feem ntau ntawm 1.0 - 2.5 hli). Thaum lub sij hawm vuam, nws yog ib qho yooj yim rau deformation xws li warping thiab dents vim tsis sib xws ntawm tshav kub input thiab kev ntxhov siab concentration, uas ncaj qha cuam tshuam rau lub sealability thiab sib dhos raug. Txawm li cas los xij, deformation tuaj yeem tswj tau zoo los ntawm kev xaiv cov khoom siv thiab kev ua kom zoo.

Ua ntej thiab qhov tseem ceeb tshaj plaws, cov khoom siv vuam zoo yuav tsum raug xaiv los txo cov cua sov tawm ntawm qhov pib. Cov tsoos chaw welders muaj lub tshav kub loj - cuam tshuam thaj tsam thaum ua kev sib cuag vuam, ua rau nyias - phab ntsa enclosures ua rau cua sov - induced deformation. Nws raug nquahu kom ua qhov tseem ceeb ntawm cov tshuab laser. With high energy density and a small spot size (controllable within 0.2 - 0.5 mm), laser welders have a heat - affected zone that is only 1/3 - 1/5 that of spot welders, significantly reducing the stress caused by uneven heating of the enclosure. Rau kev tsim khoom loj, kev sib txuas ntawm laser welders nrog cov tshuab neeg hlau yog qhov zoo dua. Cov neeg hlau laser welder muaj qhov rov ua qhov tseeb ntawm ± 0.02 hli, xyuas kom meej qhov chaw vuam seam thiab tiv thaiv lub zos deformation exacerbated los ntawm vuam deviations.

Tom ntej no los qhov tseeb tswj ntawm cov txheej txheem tseem ceeb tsis. Vuam tam sim no / lub hwj chim yuav tsum tau sib phim nrog lub thickness ntawm lub enclosure: rau ib tug 1.2 - mm - tuab aluminium alloy enclosure, ib tug laser zog ntawm 1500W thiab ib tug vuam ceev ntawm 1.5 m / min yog txaus. Thaum lub thickness nce mus rau 2.0 hli, lub hwj chim yuav tsum tau hloov mus rau 2200W thiab qhov ceev txo mus rau 0.9 m / min kom tsis txhob deformation los ntawm lub zog ntau dhau. Meanwhile, pulsed vuam hom yuav tsum hloov nruam vuam. Los ntawm lub voj voog ntawm 'pulsed zog + lub caij txias,' lub thawv tau muab sij hawm txaus rau dissipate tshav kub thiab txo cov cua sov.

Kev sib txuas ntawm vuam thiab kev tsim qauv kuj tseem ceeb heev. Lub hauv paus ntsiab lus ntawm 'symmetrical vuam, los ntawm nruab nrab mus rau qhov kawg' yuav tsum tau ua raws li: piv txwv li, rau ib lub voj voog, weld lub kab pheeb ces kaum seams ua ntej, ces plaub sab, thiab txhua sab yuav tsum tau welded nyob rau hauv seem ntawm nruab nrab mus rau qhov kawg kom tso cai rau txawm kev ntxhov siab tso tawm. Rau cov ntaub ntawv nrog stiffeners, weld lub seams txuas cov stiffeners thiab lub plhaub ua ntej txhawm rau txhim kho cov txheej txheem rigidity ua ntej welding lub peripheral seams, txo qhov muaj feem ntawm deformation.

Tsis tas li ntawd, cov cuab yeej pabcuam thiab kev kho mob tom ntej tuaj yeem tswj kev deformation ntxiv. Thaum lub sij hawm vuam, siv cov dej txias-txias cov cuab yeej los tuav lub thawv rau hauv qhov chaw. Lub fixture mating nto yuav tsum phim cov duab ntawm lub thawv kom sai sai tshem tawm cov cua sov hauv zos los ntawm cov dej txias. Tom qab vuam, muab cov ntaub thaiv npog rau hauv qhov cub hluav taws xob rau qhov kub thiab txias (txog 120 ℃ rau 2 teev rau aluminium alloy) kom tshem tawm cov kev ntxhov siab thiab tiv thaiv deformation tom qab.

Yuav kom daws tau qhov teeb meem ntawm vuam deformation ntawm cov roj teeb pob enclosures, lub compatibility ntawm cov khoom thiab cov txheej txheem yog qhov tseem ceeb. PDKJ's laser welders thiab robotic laser welders muaj kev tswj hwm lub zog. Ua ke nrog cov cuab yeej kho kom haum, lawv tuaj yeem ua kom zoo dua vuam tsis raws li cov khoom siv thiab cov tuab ntawm cov ntaub thaiv npog, ua kom zoo deformation, thiab xyuas kom vuam zoo thiab kev sib dhos raug.
