Tham txog kev ceev faj hauv lub tshuab ultrasonic vuam
Ultrasonic vuam tshuab plays lub luag haujlwm tseem ceeb hauv kev tsim khoom, tshwj xeeb tshaj yog cov khoom siv tshuab. Nws yeej pab tib neeg daws tau ntau yam teeb meem. Thaum siv lub tshuab vuam ultrasonic rau vuam, lub zog tso zis, oscillation zaus thiab amplitude ntau yam yuav tsum tau xaiv raws li cov khoom xws li workpiece khoom, vuam hlau cheeb tsam, seb puas muaj hluav taws xob cov khoom nyob rau hauv lub workpiece, thiab seb huab cua nruj yuav tsum tau. Peb yuav tsum tsis txhob ua tej yam kev txiav txim. Ultrasonic vuam tshuab yuav tsum tau nqa tawm raws li kev taw qhia ntawm cov kws tshaj lij thiab cov neeg ua haujlwm. Don'tsis mloog lwm tus. Yog tias muaj teeb meem tshwm sim, lawv yuav tsum tau kho los ntawm cov kws tshaj lij thiab cov kws tshaj lij.
Cov ntsiab lus tseem ceeb uas yuav tsum tau them nyiaj rau ultrasonic vuam tshuab yog raws li hauv qab no:
1. Lub cheeb tsam ntawm ultrasonic weld yog guaranteed kom tau raws li tej yam yuav tsum tau.
Thaum lub zog ultrasonic instantaneous generated, qhov loj ntawm qhov vuam cheeb tsam, qhov loj dua lub zog dispersion, qhov ua rau ultrasonic vuam nyhuv, thiab txawm lub weld tsis tau welded. Tsis tas li ntawd, ultrasonic tsis propagate longitudinally, thiab lub zog poob yog proportional rau kev ncua deb. Ntev-ntev ultrasonic vuam yuav tsum tau tswj tsis pub dhau 6cm. Lub ultrasonic vuam yuav tsum tau tswj ntawm 30-80 hlau. Lub thickness ntawm lub workpiece caj npab yuav tsum tsis txhob tsawg tshaj li 2 hli. Txwv tsis pub, qhov vuam tsis zoo, tshwj xeeb tshaj yog rau cov khoom uas xav tau huab cua nruj.
2. Lub melting point ntawm lub workpiece yuav tsum tau mus txog ntawm ultrasonic thermal kuj.
Lub ultrasonic transducer hloov hluav taws xob hluav taws xob rau hauv lub zog siv hluav taws xob thiab ua nws los ntawm cov khoom siv molecules ntawm lub workpiece. Txij li thaum lub acoustic tsis kam ntawm ultrasonic tsis nyob rau hauv cov khib nyiab yog ntau me dua li nyob rau hauv cov huab cua, thaum ultrasonic tsis dhau los ntawm cov pob qij txha ntawm lub workpieces, lub acoustic kuj nyob rau hauv qhov sib txawv yog loj thiab lub tshav kub generated yog loj. Ua ntej, qhov kub mus txog qhov melting point ntawm lub workpiece, thiab tom qab ntawd ib qho kev siab yog siv rau kev sib koom tes. Vim tsis muaj thermal tsis kam, lwm qhov chaw ntawm lub workpiece tsis welded ntawm qhov kub thiab txias.
3. Lub vuam seam ntawm ultrasonic welder yuav tsum nruj me ntsis soj ntsuam.
Ordinary ultrasonic vuam taub hau manufacturers muab ib txheej ntawm nruj soj ntsuam cov txheej txheem. Cov txheej txheem ua tiav tau txheeb xyuas los ntawm lub computer software simulation, thiab qhov zoo yog lav. Cov txheej txheem no tsis tuaj yeem ua tiav hauv kev cob qhia dav dav. Yog tias qhov tsim ntawm ultrasonic vuam sib koom ua ke tsis tsim nyog, qhov teeb meem tshwm sim tsis pom tseeb thaum lub tshuab ultrasonic vuam siv rau cov khoom me me. Nyob rau hauv high-power ultrasonic vuam tshuab, ntau yam tsis xws luag yuav tshwm sim, thiab lub hwj chim Cheebtsam yuav ncaj qha puas nyob rau hauv loj heev mob.
4. Lub zog tso zis ntawm ultrasonic welder yuav tsum sib npaug.
Lub zog tso zis ntawm lub tshuab ultrasonic vuam nyob ntawm txoj kab uas hla thiab thickness ntawm piezoelectric ceramic, cov khoom zoo thiab cov txheej txheem tsim. Thaum lub ultrasonic transducer txiav txim siab, lub zog yuav raug txiav txim. Kev ntsuas cov zis hluav taws xob yog txheej txheem nyuaj. Nws tsis yog hais tias qhov loj dua lub ultrasonic transducer, ntau lub hwj chim ultrasonic siv nyob rau hauv Circuit Court, lub zog tso zis ntau dua. Nws yuav tsum muaj qhov nyuaj heev. Lub ntsuas amplitude tuaj yeem ntsuas nws qhov amplitude.
5. Thaum siv lub tshuab vuam ultrasonic, ob hom workpieces tuaj yeem welded.
Qee cov ntaub ntawv sib txawv tuaj yeem welded zoo dua, qee qhov yog fused los ntawm kev xav tau yooj yim, thiab qee qhov tsis yog. Cov khoom siv tib yam muaj tib lub ntsiab lus melting thiab tuaj yeem welded nyob rau hauv txoj cai, tab sis thaum lub melting point ntawm lub workpiece yuav tsum tau welded tshaj 350 ° C, nws yog tsis tsim nyog siv lub tshuab ultrasonic vuam. Txij li cov molecules ntawm lub workpiece yaj instantly nyob rau hauv qhov kev txiav txim ntawm ultrasonic tsis, lub hauv paus kev txiav txim yog nyob rau hauv 3 vib nas this. Yog tias qhov vuam tsis zoo, koj yuav tsum xaiv lwm txoj kev vuam, xws li phaj kub vuam. Feem ntau hais lus, ABS cov ntaub ntawv yooj yim rau vuam, tab sis nylon nyuaj rau vuam.
