Kev nkag siab yuam kev ntawm ultrasonic vuam khoom
Feem ntau cov khoom siv ultrasonic vuam ua raws li ib qho ntawm ob lub tswv yim tsim: ①Modular system, ②Integrated system.
Hauv qhov system modular, cov cuab yeej tswj hwm thiab lub zog hluav taws xob raug cais tawm ntawm cov khoom siv sib kis. Thaum yuav tsum muaj kev tswj hwm qib siab thiab cov khoom siv thawj zaug xav tau kev ntim khoom yooj yim, feem ntau yog siv lub tshuab modular. Cov kev sib xyaw ua ke tsis tshua kim, tab sis tsis tshua muaj kev tswj tau.
1. Kev nkag siab yuam kev ntawm vuam txoj cai
Muaj ob peb tus neeg uas tau koom nrog ultrasonic vuam rau ntau xyoo. Muaj kev to taub yuam kev txog kev sib kis ntawm ultrasonic zog, xav tias lub suab tsis yog vuam ntawm qhov chaw sib cuag. Qhov tseeb, qhov no yog kev nkag siab yuam kev. Lub hauv paus ntsiab lus ntawm ultrasonic vuam tiag tiag yog: lub transducer converts hluav taws xob rau hauv lub tshuab tom qab lub tshuab, nws yog ua los ntawm cov khoom molecules ntawm lub workpiece, thiab acoustic tsis kam ntawm lub suab yoj nyob rau hauv cov khoom yog ntau me dua lub acoustic tsis kam nyob rau hauv cov huab cua. Thaum lub suab nthwv dej dhau los ntawm kev sib koom ua ke ntawm cov khoom ua haujlwm, acoustic kuj nyob rau hauv qhov sib txawv yog loj, thiab thermal zog generated yog loj heev. Ua ntej, lub peev xwm point ntawm lub workpiece yog mus txog, thiab ib tug tej yam siab ntxiv rau ua rau lub seam welded. Lwm qhov chaw ntawm lub workpiece yuav tsis raug welded vim yog me me thermal kuj thiab tsis kub. Lub hauv paus ntsiab lus zoo ib yam li Ohm' txoj cai lij choj hauv hluav taws xob engineering.
2. Kev nkag siab yuam kev ntawm cov khoom siv ua haujlwm:
Ultrasonic welding tshuab kuj muaj cov kev cai rau cov khoom ntawm lub workpiece yuav tsum tau welded. Tsis yog txhua yam ntaub ntawv tuaj yeem welded. Qee tus neeg nkag siab tias txhua yam khoom siv tuaj yeem welded. Qhov no yog kev nkag siab yuam kev loj. Qee cov ntaub ntawv tuaj yeem welded zoo dua. , Qee qhov yog fused, thiab qee qhov tsis fused. Lub melting point ntawm tib yam khoom yog tib yam, thiab nws yuav welded nyob rau hauv lub hauv paus ntsiab lus, tab sis thaum lub melting point ntawm lub workpiece yuav tsum welded yog ntau tshaj 350 ℃, nws tsis haum rau ultrasonic vuam. .Vim hais tias ultrasound melts lub molecules ntawm lub workpiece instantly, lub hauv paus kev txiav txim yog hais tias nyob rau hauv 3 vib nas this, yog hais tias lub vuam tsis tuaj yeem ua tau zoo, lwm yam txheej txheem vuam yuav tsum raug xaiv, xws li phaj kub vuam.
3. Cov txheej txheem tsis nkag siab ntawm ultrasonic vuam workpiece
Ultrasonic zog tawg nyob rau hauv ib qho instant, lub vuam taw tes yuav tsum yog ib tug taw tes los yog kab, thiab qhov kev ncua deb ntawm kis tau tus mob yuav tsum nyob rau hauv txoj kab nrog txoj kev vuam ultrasonic. Qee tus neeg xav tias ntev npaum li nws yog cov khoom siv yas, txawm tias qhov sib koom ua ke tuaj yeem ua tau zoo li cas, qhov no kuj yog qhov tsis nkag siab. Thaum lub zog tam sim no raug tsim, qhov loj ntawm qhov sib koom ua ke, qhov hnyav dua lub zog dispersion, qhov vuam zoo dua, thiab qhov ua rau vuam zoo dua. Tsis tas li ntawd, lub ultrasonic yoj yog longitudinally kis, thiab lub zog poob yog proportional rau qhov kev ncua deb. Qhov ntev vuam yuav tsum tswj tsis pub dhau 6 cm. Lub vuam kab yuav tsum tau tswj ntawm 30 thiab 80 xov hlau, thiab caj npab thickness ntawm lub workpiece yuav tsum tsis txhob tsawg tshaj li 2 hli, txwv tsis pub nws yuav tsis zoo welded, tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau airtightness.
4. Kev nkag siab yuam kev ntawm ultrasonic tso zis zog
Qhov loj ntawm lub zog tso zis ultrasonic yog txiav txim siab los ntawm txoj kab uas hla thiab thickness ntawm daim ntawv piezoelectric ceramic, cov khoom siv, thiab cov txheej txheem tsim. Thaum lub transducer tiav lawm, lub zog yog tiav. Kev ntsuas qhov loj ntawm cov zis hluav taws xob yog txheej txheem nyuaj, tsis yog transducer. Cov cuab yeej loj dua, cov raj siv hluav taws xob ntau dua siv nyob rau hauv Circuit Court, thiab lub zog tso zis ntau dua. Nws yuav tsum tau ib tug heev nyuaj amplitude ntsuas ntsuas kom raug ntsuas nws amplitude. Vim hais tias feem ntau cov neeg siv paub ntau dhau ntawm ultrasound, thiab qee tus neeg ua haujlwm muag khoom ua yuam kev, muab cov neeg siv khoom nkag siab yuam kev. Tus nqi hluav taws xob siv hluav taws xob tsis cuam tshuam qhov loj ntawm qhov tso zis ntau dhau lub zog. Piv txwv li, lub zog ntsug generated yog tsawg, thiab tam sim no noj yog loj, uas tsuas yog qhia tau hais tias qhov tsawg efficiency ntawm cov khoom. Lub zog reactive yog loj.
5. Kev nkag siab yuam kev ntawm ultrasonic vuam tshuab xaiv
Lub zog siv hluav taws xob ntau npaum li cas, qhov zaus oscillation, thiab qhov amplitude ntau yuav tsum tau txiav txim siab raws li cov khoom siv ntawm lub tshuab ua haujlwm, thaj tsam ntawm cov hlau vuam, seb puas muaj cov khoom siv hluav taws xob hauv lub workpiece, thiab seb nws puas yog airtight. los tsis. Kev nkag siab yuam kev tias lub hwj chim loj dua, qhov zoo dua. Qhov no kuj yog ib qho kev to taub yuam kev.
