1. Kev nkag siab yuam kev ntawm vuam workpiece

Ultrasonic zog explodes instantaneously, cov vuam kab yuav tsum tau tsim rau hauv cov ntsiab lus los yog kab thiab cov kis tau tus mob nyob deb yuav tsum ua raws li cov ultrasonic vuam txoj kev. 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 yog kev nkag siab yuam kev. Thaum lub zog tam sim no raug tsim, qhov loj ntawm qhov sib koom ua ke, qhov hnyav dua lub zog tawg, qhov ua rau vuam zoo dua, thiab txawm tias qhov vuam ua tsis tau. Ultrasonic nthwv dej tau xa mus ntev, lub zog poob yog proportional rau qhov kev ncua deb, thiab qhov ntev yuav tsum tswj tsis pub dhau 7.5 cm. Lub vuam kab yuav tsum tau tswj ntawm 0.3-0.8 hli raws li qhov zoo tshaj plaws mob, thiab phab ntsa thickness ntawm lub workpiece yuav tsum tsis txhob tsawg tshaj li 2 hli, txwv tsis pub nws yuav tsis tau welded zoo, tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau watertightness.

2. Kev nkag siab yuam kev ntawm cov khoom siv ua haujlwm

Ultrasonic welding tshuab muaj qhov yuav tsum tau ntawm cov ntaub ntawv ntawm welded workpieces. Tsis yog txhua yam ntaub ntawv tuaj yeem welded. Qee tus neeg xav tias txhua yam khoom siv tuaj yeem welded. Qhov no yog kev nkag siab yuam kev loj. Qee cov ntaub ntawv sib txawv tuaj yeem welded zoo, thiab qee qhov tuaj yeem welded. Qee qhov tsis sib xws. Lub melting point ntawm tib cov khoom yog tib yam, thiab nws yuav tsum tau welded nyob rau hauv txoj cai. Tab sis thaum lub melting point ntawm lub welded workpiece yog ntau tshaj 350 degrees, nws yog tsis tsim nyog rau ultrasonic vuam. Vim tias ultrasound melts cov molecules ntawm lub workpiece instantaneously, lub hauv paus ntawm kev txiav txim yog nyob rau hauv 1-3. Yog tias qhov vuam tsis zoo, koj yuav tsum xaiv lwm cov txheej txheem vuam, xws li cov phaj kub, kiv melting, kev co thiab kev sib txhuam. Feem ntau hais lus, cov khoom siv ABS yog qhov yooj yim tshaj plaws rau vuam vim nws qhov qis melting point thiab hardness. Ntawm qhov tsis sib xws, nylon yog qhov nyuaj tshaj plaws rau vuam.

3, Ua yuam kev hauv kev xaiv ultrasonic

Ntau npaum li cas tso zis zog siv, oscillation zaus, thiab amplitude ntau yuav tsum tau txiav txim siab raws li cov khoom ntawm lub workpiece, lub cheeb tsam ntawm lub vuam hlau, seb puas muaj hluav taws xob Cheebtsam nyob rau hauv lub workpiece, thiab seb nws yog airtight. Myth yog hais tias lub zog loj dua, qhov zoo dua. Qhov no kuj yog ib qho kev to taub yuam kev. Yog tias koj tsis paub ntau txog ultrasound. Nws yog qhov zoo tshaj plaws los tham txog engineering thiab cov neeg ua haujlwm ntawm cov nroj tsuag ultrasonic tsis tu ncua. Yog tias ua tau, nws yog qhov zoo tshaj rau kev sib txuas lus nrog cov chaw tsim khoom ntawm qhov chaw, thiab tsis txhob mloog qhov tsis txaus ntseeg ntawm qee tus neeg ua haujlwm muag khoom tsis raug cai ultrasound. Tam sim no, cov tuam txhab uas tsim cov cuab yeej muaj feem cuam tshuam tshwj xeeb, feem ntau yog tsev neeg kev cob qhia, uas luam tawm lub voj voog nruj, thiab zoo li nkag siab txog txoj hauv kev ua haujlwm. Cov cuab yeej theej muaj qhov tsis txaus ntseeg. Ib qho yog tias qhov zoo ntawm cov khoom siv raw yuav tsis tuaj yeem lav, thiab cov thev naus laus zis tseem ceeb ntawm cov txheej txheem tsim khoom thib ob tsis tau ua tiav. Cov khoom siv feem ntau ua haujlwm tsis ruaj khov thaum lub sijhawm nruab nrab thiab siab zog ua haujlwm, thiab cov khoom tsim nyog tus nqi qis. Qee zaum cov khoom siv puas lawm. Xws li lub zog hloov hluav taws xob ntawm lub tshuab hluav taws xob, qhov tsis sib nqus ntawm cov khoom siv sib nqus tsis tuaj yeem ntsuas, sib nqus saturation magnetic flux ntom (Bs), magnetic induction intensity (Bm), zoo magnetic permeability (Ue), residual magnetic flux density (Br), coercivity (A / M) thiab lwm yam. Yog li ntawd, mus yuav ultrasound, nws yog qhov zoo tshaj kom nkag siab txog lub tuam txhab qhov xwm txheej ua ntej. Tsuas yog nyob rau hauv txoj kev no tuaj yeem txo qhov teeb meem tsis tsim nyog rau yav tom ntej.

4, kev nkag siab yuam kev ntawm ultrasonic tso zis zog

Lub zog tso zis ntawm ultrasonic yoj yog tib yam li txoj kab uas hla thiab tuab ntawm piezoelectric ceramic ntawv, cov khoom siv, thiab cov txheej txheem tsim. Lub transducer yog zoo li tus thiab lub zog siab tshaj plaws yog zoo li tus. Kev ntsuas lub zog tso zis yog txheej txheem nyuaj. Nws tsis yog tias qhov loj dua lub transducer, ntau lub hwj chim raj siv nyob rau hauv Circuit Court, lub zog tso zis ntau dua. Nws yuav tsum xav tau ib qho kev ntsuas amplitude kom meej meej ntsuas nws qhov amplitude. Ua ke nrog kev ua yuam kev ntawm cov neeg ua haujlwm muag khoom, nws ua rau cov neeg siv khoom nkag siab tsis ncaj ncees lawm tias cov khoom siv hluav taws xob siv hluav taws xob tsis cuam tshuam qhov loj ntawm cov zis ultrasonic zog. Yog hais tias lub zog longitudinal generated yog tsawg thiab kev siv tam sim no loj, nws tsuas tuaj yeem piav qhia txog kev ua haujlwm ntawm cov khoom siv, tsis muaj lub zog. Hais.

5. Kev nkag siab yuam kev hauv txoj cai vuam

Muaj coob tus neeg uas tau koom nrog hauv ultrasonic vuam rau ntau xyoo muaj kev nkag siab tsis zoo txog kev sib kis ntawm ultrasonic zog. Nws ntseeg tau hais tias kev sib txuas ntawm lub suab tsis nyob ntawm qhov chaw sib cuag yog qhov tsis to taub. Qhov tseeb vuam txoj hauv kev yog tias tom qab lub transducer hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob, nws dhau los ntawm qhov chaw ua haujlwm Cov khoom siv molecules coj, thiab lub suab nthwv dej ua rau lub suab tsis kam nyob hauv cov khib nyiab me dua li hauv huab cua. Thaum lub suab nthwv dej dhau los ntawm kev sib koom ua ke ntawm cov khoom ua haujlwm, acoustic tsis kam nyob rau hauv qhov sib txawv loj, thiab lub zog thermal generated yog loj heev. Qhov kub ua ntej ncav cuag lub melting point ntawm lub workpiece, thiab tom qab ntawd nrog ib tug tej yam siab, lub seam yog welded, thiab lwm yam qhov chaw ntawm lub workpiece yuav tsis welded vim tsis muaj acoustic tsis kam thiab tsis kub. Lub hauv paus ntsiab lus zoo ib yam li Ohm txoj cai.

6, Kev nkag siab yuam kev ntawm vuam qauv

Ntau hom ultrasonic pwm (Horn), cov duab ntawm lub workpiece txiav txim siab cov duab ntawm cov pwm, tab sis qhov loj thiab radian ntawm txhua qhov yuav tsum nruj me ntsis suav. Qee tus neeg yuam kev xav tias nws tsuas yog ib qho thaiv hlau xwb. Txawm hais tias tus qauv tsim tsim nyog lossis tsis ncaj qha cuam tshuam rau kev ua tau zoo, lub neej ntev, cov khoom tsim nyog tus nqi ntawm cov pwm, thiab ncaj qha hlawv tawm lub tshuab hluav taws xob hauv qhov xwm txheej hnyav. Cov khoom siv ntawm cov pwm feem ntau yog magnesium aluminium 7075, thiab qee cov neeg siv cov ntaub ntawv tsis zoo los txo cov nqi. Cov tuam txhab pwm tsis tu ncua muaj cov txheej txheem tshuaj xyuas nruj rau cov khoom tuaj, thiab cov txheej txheem ua tiav tau ua tiav tom qab lub khoos phis tawj software simulation thiab pov thawj. Zoo yog guaranteed. Cov txheej txheem no tsis tuaj yeem ua los ntawm kev cob qhia dav dav. Yog tsis tsim nyog tsim, cov pwm tsim yuav tsis muaj teeb meem tshwm sim thaum vuam me me workpieces. Ntau yam tsis zoo yuav tshwm sim thaum siv hluav taws xob siab. Hauv cov xwm txheej hnyav, ncaj qha ua rau cov khoom puas
