Dab tsi yuav tsum tau ceeb toom thaum txhim kho cov khoom rau hauv cov roj teeb thiab tom qab ntawd Ultrasonic Vuam?
Jan 09, 2024
1. Kauj Ruam tawm ntawm qhov tsis ncaj ncees lawm ntawm ultrasonic vuam: zaus ntawm oscillation, tso zis zog, amplitude ntau, thiab lwm yam yuav tsum tau txiav txim raws li tej yam xws li welding hlau cheeb tsam, cov khoom, seb lub workpiece yog airtight nrog electrons, thiab seb nws yog ib feem. Qhov kev xav tsis zoo tias lub zog siab dua yog qhov kev xav tsis zoo. Yog tias koj tsis paub txog ultrasound. Nws yog qhov zoo tshaj plaws los sab laj txog engineering thiab cov neeg ua haujlwm technical.
2. Welding tuag qauv yuav tsum tau soj ntsuam nruj: Tsis tu ncua ultrasonic tuag ntau lawm muaj ib tug nruj soj ntsuam kev pab cuam rau cov khoom tuaj, thiab ua qhov ntev yog tag nrho cov txheej txheem los ntawm lub computer software simulation thiab pov thawj. Qhov zoo yog qhov lav. Cov txheej txheem no feem ntau tsis tuaj yeem ua tiav hauv kev cob qhia. Yog tias pwm tsis tsim kom zoo, qhov teeb meem tshwm sim yuav tsis pom tseeb thaum vuam me me workpieces. Thaum lub hwj chim siab, ntau yam teeb meem yuav tshwm sim, thiab thaum muaj xwm txheej hnyav, cov khoom siv hluav taws xob yuav raug puas tsuaj ncaj qha.

3. Thaum vuam, thermal kuj yuav tsum ncav cuag lub melting point ntawm lub workpiece: Tom qab lub ultrasonic transducer converts hluav taws xob lub zog rau hauv txhua yam zog, nws yog kis los ntawm cov khoom molecules ntawm lub workpiece. Lub acoustic tsis kam ntawm ultrasonic suab tsis nyob rau hauv cov khoom yog qis dua li nyob rau hauv cov huab cua. Thaum lub suab nthwv dej dhau los ntawm cov seam ntawm lub workpiece, lub acoustic tsis kam nyob rau hauv qhov sib txawv yog loj, thiab lub zog hluav taws xob generated muaj ntau heev. Qhov kub nce mus txog qhov melting point ntawm lub workpiece, thiab ib tug npaum li cas ntawm lub siab yog siv rau fuse lub sib koom tes. Txawm li cas los xij, lwm qhov ntawm lub workpiece yuav tsis raug fused vim tsis muaj thermal tsis kam thiab tsis kub.
4. Weldability ntawm ob hom workpieces thaum vuam: qee qhov tuaj yeem ua tau zoo dua fused ntawm cov khoom sib txawv, qee qhov tuaj yeem fused, thiab qee qhov tsis tuaj yeem fused. Lub melting point ntawm tib cov khoom yog tib yam, thiab theoretically nws tuaj yeem welded. Txawm li cas los xij, thaum lub melting point ntawm lub workpiece yuav tsum welded yog ntau tshaj 350 degree, ultrasonic vuam tsis haum lawm. Vim tias ultrasound tam sim ntawd ua rau cov molecules ntawm lub workpiece yaj, nws raug txiav txim tias nws yog nyob rau hauv 3 vib nas this thiab tsis tuaj yeem fused zoo, yog li lwm cov txheej txheem vuam yuav tsum raug xaiv. Feem ntau hais lus, cov khoom siv ABS yog qhov yooj yim tshaj plaws rau vuam, thaum cov khoom nylon lossis PP feem ntau weldable.
5. Muaj qee qhov yuav tsum tau ua rau thaj tsam vuam: thaum lub zog ultrasonic instantaneous tsim, qhov loj dua qhov vuam cheeb tsam, qhov loj dua lub zog dispersion, thiab qhov ua rau vuam zoo, uas yuav tiv thaiv vuam. Tsis tas li ntawd, ultrasonic tsis propagate longitudinally, thiab lub zog poob yog proportional rau kev ncua deb. Qhov kev ncua deb vuam yuav tsum tswj tsis pub dhau 6 centimeters. Lub vuam hlau 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 millimeters, txwv tsis pub nws yuav tsis zoo fused, tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau airtightness.
6. Lub zog tso zis ntawm ultrasonic vuam yuav tsum sib npaug: qhov loj ntawm cov khoom siv hluav taws xob yog txiav txim siab los ntawm lub thickness thiab txoj kab uas hla ntawm piezoelectric ceramic los xij, txheej txheem tsim, cov khoom siv, thiab lwm yam. Thaum lub ultrasonic transducer yog tsau, lub zog siab tshaj plaws kuj yog. tsau. Kev ntsuas qhov loj ntawm cov zis hluav taws xob yog cov txheej txheem nyuaj, thiab nws tsis yog qhov loj dua ntawm ultrasonic transducer, ntau dua qhov tso zis zog siv hauv Circuit Court. Qhov ntau ultrasonic fais fab raj muaj, qhov nyuaj amplitude ntsuas ntsuas yuav tsum tau, Tsuas yog ces nws amplitude yuav raug ntsuas.
