1. Kev yuam kev ntawm vuam workpiece
Lub zog ultrasonic tawg tam sim ntawd, thiab lub vuam kab yuav tsum tau tsim rau hauv cov ntsiab lus lossis kab thiab qhov kev sib kis tau deb yuav tsum yoog nrog cov txheej txheem ultrasonic welding. Qee tus neeg xav tias ntev li ntev tau yog cov khoom siv yas, tsis muaj teeb meem sib koom ua ke lub ntsej muag tuaj yeem ua ke zoo, qhov no yog qhov kev nkag siab yuam kev. Thaum muaj kev cuam tshuam hluav taws xob tam sim ntawd, qhov loj dua ntawm qhov sib koom ua ke, qhov ntau ntawm lub zog tawg, qhov tsis zoo ntawm cov vuam, thiab txawm tias vuam ua tsis tau. Tsis tas li ntawd Ultrasonic xaim yog kis tau ntev ntev, lub zog poob yog sib npaug rau qhov deb, thiab qhov ntev yuav tsum raug tswj tsis pub dhau 7.5 cm. Lub vuam kab yuav tsum raug tswj ntawm 0.3-0.8mm raws li cov xwm txheej zoo tshaj plaws, thiab lub phab ntsa tuab ntawm lub workpiece yuav tsum tsis pub tsawg dua 2 hli, txwv tsis pub nws tsis tuaj yeem txuas zoo, tshwj xeeb tshaj yog rau cov khoom uas xav tau dej.
2. Kev yuam kev ntawm cov khoom siv workpiece
Cov tshuab nqus hlau ultrasonic muaj qhov yuav tsum tau ua ntawm cov khoom siv ntawm cov txig welded. Tsis yog txhua cov ntaub ntawv tuaj yeem siv tau. Qee tus neeg xav tias txhua yam khoom siv tuaj yeem tau txais. Nov yog kev to taub yuam kev loj heev. Qee cov ntaub ntawv tuaj yeem txuas tau zoo thiab qee qhov tuaj yeem txuas tau. Qee qhov tsis sib xws. Lub ntsiab lus yaj ntawm cov khoom siv tib yam, uas tuaj yeem ua welded hauv txoj ntsiab cai. Tab sis thaum lub ntsiab lus melting ntawm qhov chaw ua haujlwm welded yog ntau dua 350 degrees, nws tsis haum rau ultrasonic welding. Vim tias ultrasound melts cov lwg me me ntawm lub haujlwm ua haujlwm tam sim ntawd, kev txiav txim siab raws li 1-3. Yog tias lub vuam tsis zoo, koj yuav tsum xaiv lwm cov txheej txheem vuam, xws li lub phaj kub, kiv kiv, kev co thiab txhuam. Feem ntau hais lus, ABS cov khoom siv yog qhov yooj yim tshaj plaws vim li cas nws qhov melting point thiab hardness. Ntawm qhov tsis tooj, nylon yog qhov nyuaj tshaj plaws rau weld.
3. Yuam kev hauv kev xaiv ultrasonic
Cov khoom siv hluav taws xob ntau npaum li cas, oscillation zaus thiab qhov ntau ntau siv tau siv nyob ntawm yam tseem ceeb xws li cov khoom siv ntawm qhov chaw ua haujlwm, thaj chaw ntawm cov hlau hlau, seb puas muaj cov khoom siv hluav taws xob hauv qhov haujlwm, thiab seb nws yog airtight. Tswvyim hais yog qhov muaj hwj chim ntau dua, ntau dua. Qhov no tseem yog kev to taub. Yog tias koj tsis txhob' t paub ntau txog ultrasound. Nws yog qhov zoo tshaj plaws los sab laj rau engineering thiab cov neeg ua haujlwm ntawm ib qho kev tsim cov tshuab ultrasonic ntau lawm. Yog tias ua tau, nws yog qhov zoo tshaj rau kev sib txuas lus nrog cov chaw tsim khoom hauv chaw, thiab tsis txhob dig muag qhov tsis mloog ntawm qee cov neeg ua haujlwm sab nrauv ultrasound muag. Tam sim no, cov tuam txhab lag luam uas tsim cov khoom siv cuam tshuam yog qhov nyuaj, feem ntau yog kev ua haujlwm hauv tsev neeg, uas luam cov ntawv sib dhos, thiab zoo li nkag siab lub hauv paus ntsiab lus ua haujlwm. Cov khoom siv theej tau muaj cov ua haujlwm tsis zoo. Ib qho yog tias qhov zoo ntawm cov khoom siv ua lag luam tsis tuaj yeem lav, thiab lub thib ob yog tias cov cuab yeej tseem ceeb ntawm cov txheej txheem ntau lawm tsis yog mas. Cov khoom siv feem ntau ua tsis ruaj khov thaum nruab nrab thiab siab zog ua haujlwm, thiab cov khoom muaj txiaj ntsig tus nqi yog tsawg. Qee zaum cov khoom siv yuav piam lawm. Xws li lub zog hloov hluav taws xob ntawm lub transducer, cov khoom siv sib nqus tsis muaj peev xwm ntsuas tsis tau, lub suab sib nqus magnetic flux ceev (Bs), sib nqus induction sib nqus (Bm), zoo sib nqus permeability (Ue), sib nqus residual flux ceev (Br), coercive kev quab yuam (A / M) thiab lwm yam. Cov txheej txheem winding yog qhov nyuaj heev, thiab cov rooj cob qhia hauv tsev no tsis tuaj yeem ua. Yog li, txhawm rau yuav ultrasound, nws yog qhov zoo tshaj plaws kom nkag siab txog tuam txhab' s qhov xwm txheej ua ntej. Tsis txhob' t blindly ua raws li tus muag' s touted, thiab tsis txhob' t tsuas xav tau tus nqi. Tsuas yog txoj hauv kev no thiaj tuaj yeem tsim teeb meem tsis txaus ntseeg txo tau yav tom ntej.
4, kev nkag siab yuam kev ntawm ultrasonic tso zis ntau zog
Lub zog tsim tawm ntawm ultrasonic nthwv dej yog tib yam li lub taub thiab tuab ntawm piezoelectric ceramic daim ntawv, cov khoom siv, thiab txheej txheem tsim. Tus transducer yog zoo li tus thiab lub zog tshaj plaws yog zoo li tus. Ntsuas cov zis tawm hluav taws xob yog qhov txheej txheem nyuaj. Nws tsis yog tias qhov loj dua qhov transducer, ntau txoj hlab hluav taws xob hauv Circuit Court siv, ntau cov khoom siv hluav taws xob. Nws yuav tsum muaj qhov ntsuas qhov tsim nyog los ntsuas qhov ntsuas kom ncaj nws lub peev xwm. Vim tias feem ntau cov neeg siv tsis paub ntau txog kev siv suab nrov, Ua ke nrog cov neeg ua haujlwm muag khoom tsis raug, nws muab cov neeg siv khoom yuam kev tsis to taub tias cov hluav taws xob ntau npaum li cas tsis cuam tshuam qhov loj me ntawm cov zis ultrasonic zog. Piv txwv li, lub zog ntev qis thiab kev siv hluav taws xob ntau tam sim no tsuas yog piav qhia txog kev ua haujlwm ntawm cov khoom siv thiab tsis muaj zog. Hais.
5. Kev yuam kev ntawm kev siv hlau ua haujlwm
Coob tus naj npawb ntawm cov neeg uas tau koom nrog ultrasonic vuam siv ntau xyoo muaj kev nkag siab yuam kev txog kev sib kis ntawm ultrasonic zog. Nws ntseeg tau tias lub vuam ntawm lub suab vuam ntawm qhov chaw sib chwv yog qhov kev nkag siab tsis meej. Qhov tseeb vuam txoj cai yog tias tom qab tus hloov pauv hloov hluav taws xob lub zog rau hauv kev siv zog lub zog, nws dhau los ntawm qhov chaw ua haujlwm cov khoom siv molecules coj, thiab lub suab sib txuas ua suab muaj feem cuam tshuam hauv cov dej khib nyiab tsawg dua li ntawm cov pa. Thaum lub suab nthwv dej hla los ntawm qhov sib koom ua haujlwm ntawm qhov haujlwm, qhov tawm tsam hauv qhov txawv yog qhov loj, thiab lub zog tsim thermal yog loj heev. Qhov kub ua ntej tau mus txog qhov chaw yaj ntawm cov haujlwm tawm, thiab tom qab ntawd Nrog qee qhov siab, lub seam yog welded, thiab lwm qhov chaw ntawm lub workpiece yuav tsis tau welded vim yog lub suab acoustic tsis kam thiab tsawg kub. Lub hauv paus ntsiab lus zoo ib yam li Ohm' s txoj cai lij choj.
6, Kev yuam kev ntawm vuam qauv
Txawv ntawm cov pwm ntawm ultrasonic pwm (Horn), qhov haujlwm ntawm qhov haujlwm los txiav txim siab qhov zoo ntawm cov pwm, tab sis qhov loj me thiab radian ntawm txhua ntu thiab cov khoom yuav tsum tau muab xam nruj me ntsis. Qee tus neeg yuam kev xav tias nws tsuas yog hlau thaiv xwb. Txawm hais tias tus qauv tsim nyog ncaj qha cuam tshuam rau pwm kev ua haujlwm, lub neej, cov khoom tsim nyog tus nqi, thiab ncaj qha hlawv lub tshuab hluav taws xob hauv cov mob loj. Cov khoom siv ntawm cov pwm feem ntau siv txhuas aluminium 7075, thiab qee tus neeg siv cov ntaub ntawv qis dua los txo tus nqi. Cov pwm ua niaj zaus tsim muaj txheej txheem nruj soj ntsuam cov txheej txheem rau cov khoom xa tuaj, thiab cov txheej txheem qhov ntev tau ua tiav tom qab khoos phis tawj software simulation thiab kev kuaj xyuas. Cov khoom lag luam zoo yog guaranteed. Cov txheej txheem no tsis tuaj yeem raug ua nyob rau hauv cov rooj cob qhia dav dav. Yog tias tsis muaj kev tsim qauv tsim nyog, cov pwm tsim los yuav tsis muaj cov teeb meem tshwm sim pom tseeb thaum ua haujlwm welding me me. Ntau yam tsis zoo yuav tshwm sim thaum lub zog loj tau siv. Hauv cov xwm txheej hnyav, ncaj qha ua rau cov khoom puas.
