Kev tsim kho vuam ultrasonic hauv kev vuam cov tsheb yas ntu
Ultrasonic automotive yas vuam Ultrasonic vuam txhais: Ultrasonic vuam yog lub thev naus laus zis ua haujlwm siab rau vuam cov yas ua khoom yas. Txij li thaum daim ntawv thov ntawm cov thev naus laus zis tuaj yeem hloov qhov flux, nplaum, studs lossis lwm yam kev kho kho tshuab kev ua haujlwm yav dhau los, kev ua haujlwm ntau lawm tau raug tsim kho thiab tus nqi txo. Lub hauv paus ntsiab lus ntawm ultrasonic vuam yog los hloov qhov hluav taws xob loj hloov mus ua lub zog hluav taws xob ntau dhau los ntawm lub tshuab hluav taws xob ultrasonic, thiab tom qab ntawd cov lus tsa suab kho tshuab tau xa mus rau lub taub hau vuam los ntawm kev teeb tsa cov khoom siv hluav taws xob uas tuaj yeem hloov kho cov amplitude. Lub taub hau vuam hloov mus rau qhov tau txais kev vibration lub zog rau kev sib koom ua haujlwm ntawm qhov chaw ua haujlwm kom tau txais welded. Nyob hauv thaj chaw no, lub zog kev hloov pauv tau hloov mus ua hluav taws xob kub los ntawm kev sib txhuam kom yaj cov yas. Ultrasound tuaj yeem siv tsis yog rau weld nyuaj los xij, tab sis kuj tseem yuav ua cov ntaub thiab cov ua yeeb yaj kiab.
Qhov zoo thiab tsis zoo ntawm ultrasonic vuam nyob hauv kev lag luam tsheb: Cov txiaj ntsig zoo ntawm ultrasonic welding: ceev ceev thiab tsis siv neeg. Qhov tsis zoo ntawm ultrasonic vuam: txwv los ntawm qhov loj me, cov duab thiab cov khoom siv (ultrasonic vuam yog feem ntau rau PP, PC, ABS, PA, PS, AMMA plastics)
Tus qauv tsim ntawm ultrasonic welding nto yog inclined nto vuam kom ua tiav tiav qhov chaw txuas. Txij li thaum cov cua sov ua haujlwm lub zog thiab qhov chaw loj dua vuam tuaj yeem tau txais, lub zog vuam ntau dua thiab cov cua nruj heev. Kev sib koom ua ke yog los ntawm shear vuam, thiab cov cua kub tsis zoo yog tau los ntawm cov nplaim sib txuam hauv cov kev taw qhia kev co, thiab nws cov huab cua nruj thiab vuam lub zog zoo heev. Txawm li cas los xij, lub eeb tsim tawm tom qab vuam yuav nyob rau saum npoo, tshwj xeeb tshaj yog thaum lub eeb tsis tso cai, ceev faj. Txiab txoj kev koom nrog yog nyob nruab nrab ntawm cov hais los saum toj no-koom bevel kev sib koom ua ke thiab muaj kev sib koom ua ke. Vim tias nws cov airtightness zoo, nws tuaj yeem ua tau zoo weld duab lwm lub voj voog, yog li nws tau siv ntau zaus. Lub zog-koom kev koom ua ke yog koom nrog kev tsim qauv qhov kev siv hluav taws xob muaj qhov muaj zog ntawm convex ib feem ntawm daim duab peb sab hu ua kev taw qhia, thiab lub cua sov los ntawm qhov cuam tshuam ntxiv. Qhov zoo dua yog tias cov duab yog yooj yim thiab txoj kev txwv ntawm kev sib koom ua ke yog qhov me me. Txawm li cas los xij, rau cov kab hluav taws xob crystalline, ntau dhau los ntawm cov cua kub hauv zos yuav ua rau cov muag muag thiab yaj, uas yuav ua rau lub siab vuam kev poob siab thiab tsis zoo airtightness, uas yuav tsum tau them sai sai rau.
Ultrasonic welding tej yam kev mob: Raws li cov xwm txheej ntawm ultrasonic vuam, qhov tseem ceeb yog qhov ntev ntawm lub sijhawm (kev co, vuam lub sijhawm) thiab siab thov rau vuam zog. Yog lawm, lwm yam mob kuj tseem ceeb heev. Vuam kub Qhov kub vau txaus kub ntawm cov khoom siv vuam ultrasonic. Txwv tsis pub cov khoom siv yuav tsis yaj. Muaj feem cuam tshuam rau kev ua kom dav, ntau dua qhov ntau, qhov siab kub nce ntxiv. Cov xovxwm quab yuam siv ib qho cuab yeej sib nqus los txhawm rau txhawm rau tsim cov khoom pwm. Feem ntau, qhov ntsuas cua nra yog 0.1-0.3MPa (ntsuas lub zog), qee zaum siab dua. Txawm li cas los xij, yog tias siv lub siab loj, siv lub tshuab voos kheej kheej yuav raug muab zais. Lub sijhawm vuam sijhawm nws txawv nyob ntawm cov khoom siv thiab cov duab ntawm cov khoom, thiab lub sijhawm vuam ntawm qee cov khoom lag luam pwm tsuas yog 0.2 vib nas this. Lub sijhawm ntev dhau lawm yuav ua rau muaj vuam ntau thiab tsim ntau cov nyem thiab cov npuas, uas yuav ua rau lub cev tsis zoo, yog li yuav tsum tau them nyiaj. Lub sijhawm txias (tuav) Lub sijhawm Rau plooj plooj (crystalline plastics), yog tias qhov ntsuas kub qis dua qhov chaw melting, qhov sib txuas yuav ua kom sib zog, thiab lub sijhawm siab feem ntau tswj ntawm 0.1 thiab 0.2 vib nas this.
Ultrasonic vuam tshuab yuav tsum tau ua: vuam lub taub hau tau muab faib ua peb ntu los hauv qab mus rau sab saum toj: vuam taub hau, ua kom nrov zog thiab hloov pauv. Qhov peb tau nthuav dav raws li qee qib. Yog hais tias qhov ntau ntawm cov transducer yog 6MM, cov tshuab ntsuas kom tuaj yeem nthuav dav peb zaug mus rau 18MM, thiab qhov dav txav mus rau lub taub hau vuam tuaj yeem raug nce rau 36MM. Ntawm chav kawm, raws li lub zog hloov ntxiv, lub neej ntawm vuam taub hau yuav poob qis. Cov ntawv sib txawv kom tau welded yuav tsum muaj ntau qhov sib txawv. Muaj feem ntau peb hom vuam taub hau cov ntaub ntawv: Titanium: kim, kev ua tau zoo, zoo toughness, thiab ua haujlwm nyuaj. Kev txhuam txhuam poob me me, thiab qhov dav dav tuaj yeem ncav cuag 60MM; aluminium alloy: pheej yig, hnav ceev, ntsig tsis tuaj yeem tsis dhau 30MM, yooj yim rau txheej txheem; steel: tawv heev, tsis haum rau vuam taub hau, qhov loj tsis tuaj yeem tshaj 25MM, tsim nyog rau kev txiav, xav kom nce cov tog raj xa pa, Yooj yim txias.
Daim ntaub ntawv siv vuam tsheb hauv ultrasonic: tsheb lub qhov rooj vaj huam sib luag, tsheb qhov rooj vaj huam sib luag lub suab rwb thaiv tsev muaj kev xav, tsheb tsis phom sij sab hauv qhov chaw vuam, tsheb dashboards, tsheb dashboards, tsheb yas seem riveting, tsheb bumpers, npog lub log tsheb, lub tsheb hlau, lub cev tsheb tsis yog cov ntaub qhwv tsis haum, cov ntaub qhwv tsis haum rau lub rooj zaum hauv lub tsheb, lub tshuab tsheb npog, tsheb tog, cov lus qhia siv lub tsheb, cov tsheb caws tsheb, cov hnab looj tes lub tsheb, lub tsheb lim, lub rooj tsav tsheb hauv lub tsheb, lub tsheb sib tiv toj hauv tsheb, lub tshuab tsheb airflow tos. Rau cov vuam ntawm cov khoom siv hauv lub tsheb yas, cov khoom tsis yog ultrasonic txheem vuam siv feem ntau yog siv, ntau lub taub hau ntau qhov chaw nres tsheb tsim, nrog PCL qhov kev tswj hwm kev tswj hwm thiab LCD cov haujlwm ua haujlwm, vuam ntawm cov cuab yeej ua haujlwm loj hauv cov tsheb loj, suav nrog cov vuam chaw hauv ntau cov , thiab ntau qhov chaw xav tau yuav tsum tau welded tib lub sijhawm.
