Lub hauv paus ntsiab lus ntawm 20KHZ ultrasonic yas vuam tshuab
Lub hauv paus ntsiab lus ntawm ultrasonic yas vuam yog los hloov 20KHZ (lossis 15KHZ) high-voltage high-frequency cov paib ua tawm los ntawm lub tshuab hluav taws xob mus rau high-frequency mechanical kev co los ntawm lub zog hloov hluav taws xob, thiab tom qab ntawd siv nws rau cov yas ua haujlwm thiab ua rau hloov mus los cov nto thiab sab hauv molecular qhov chaw. Lub interface kub nce mus. Thaum qhov kub mus txog melting point ntawm lub hom phiaj nws tus kheej, lub interface ntawm lub workpiece yuav yaj sai thiab tom qab ntawd sau qhov sib txawv ntawm kev cuam tshuam. Thaum kev co tso tseg, nws nyob hauv qab ib qho siab thaum tib lub sijhawm. Tom qab txias thiab tsim, lub vuam tuaj yeem ua tiav.
Thaum ultrasonic vuam ua rau qhov chaw sib cuag ntawm thermoplastics, kaum tawm txhiab tus neeg ua haujlwm siab-ntau zaus tsaj tawm ntawm txhua ob. Qhov kev ntsuas siab loj no nrog qee qhov kev hloov pauv yuav hloov lub zog ultrasonic rau thaj chaw vuam mus los ntawm qhov txuas ntawm qhov txuas sab saud. Vim tias qhov chaw vuam yog ob qho. Lub suab mloog tsis kam ntawm lub vuam interface yog qhov loj heev, yog li qhov ntsuas kub hauv zos yog tsim tawm. Tsis tas li ntawd, vim muaj qhov tsis zoo thermal conductivity ntawm cov yas, nws tsis tuaj yeem faib thiab sib sau ua ke nyob rau hauv qhov chaw vuam mus rau ib lub sijhawm, uas ua rau qhov chaw tiv thaiv ntawm ob lub plastics yuav yaj sai tom qab muaj qee qhov kev thov siab. , Nws koom rau hauv ib qho. Thaum lub ultrasound nres, cia lub siab txuas ntxiv rau ob peb lub vib nas this los ua kom muaj zog thiab ua kom zoo nkauj, thiaj li tsim cov txheej txheem sib nqus molecular kom ua tiav lub hom phiaj ntawm vuam, thiab lub zog vuam tuaj yeem nyob ze rau lub zog ntawm cov khoom siv raw. Qhov zoo ntawm ultrasonic yas vuam nyob ntawm peb yam: qhov loj ntawm lub vuam taub hau ntawm qhov hloov pauv, lub siab ua ntawv thov thiab lub sijhawm vuam. Lub sijhawm vuam thiab vuam taub hau siab tuaj yeem hloov kho, thiab qhov dav txiav txim tau txiav txim siab los ntawm qhov sensor thiab vuam taub hau. Kev sib cuam tshuam ntawm qhov peb muaj nuj nqis no muaj tus nqi tsim nyog. Thaum lub zog ua tus nqi tshaj qhov tsim nyog, lub melting nqi ntawm cov yas yog loj thiab cov khoom siv vuam tau yooj yim deformed; thaum lub zog ntau dua tus nqi tsim nyog, lub vuam khoom siv tau yooj yim deformed. Thaum lub zog ntau dua tus nqi tsim nyog, lub vuam khoom siv tau yooj yim deformed. Thaum lub zog tshaj tus nqi tsim nyog, lub vuam khoom siv tau yooj yim deformed. Yog tias lub zog hluav taws xob tsawg, nws tsis yooj yim rau weld khov kho, thiab lub siab thov yuav tsis loj heev. Lub siab ua tau yog cov khoom ntawm sab ntev ntawm qhov txuas ntawm welded thiab lub siab rau 1 hli ntug.
Hangzhou Altrasonic' s lub tshuab vuam tshuab ultrasonic thiab tshuab vuam siv ultrasonic siv lub zog ntawm lub zog hluav taws xob uas tsim los ntawm ultrasonic qhov loj cov tshuab kev co. Ua cov yas deformation ntawm qhov chaw ua haujlwm thiab rhuav tshem cov txheej hauv qab siab kom cov hlau txuas uas muaj lub cev sib txuas ntawm chav tsev kub. Kev ua kom zoo thaum tshav kub ua kom sov tau zoo dua, thiab ultrasonic vuam muaj qee yam zoo hauv cov nqi khoom. Qhov chaw nruab nrab ntawm lub tshuab vuam ultrasonic yog 20KHz, 40KHz, thiab lwm yam. Lub sijhawm ua haujlwm ntawm lub vuam siv tshuab feem ntau yog nyob ntawm cov tshuab resonance zaus ntawm lub transducer, vuam taub hau thiab taub hau vuam. Kho cov zaus ntawm lub tshuab hluav taws xob raws li cov khoom siv tshuab resonance zaus kom ua tiav qhov sib xws thiab ua kom lub taub hau vuam tig rov qab. Txhua ntu yog tsim los raws li ib nrab nthwv dej resonator. Lub tshuab nqus hlau ultrasonic feem ntau ntsib qee qhov teeb meem tsis zoo thaum vuam cov khoom, cov teeb meem no yuav cuam tshuam rau cov txheej txheem ntau lawm thiab ua puas rau cov yas yas ntawm cov khoom! Yuav kho li cas qhov kev puas tsuaj no?
Tom qab tig lub tshuab welding ultrasonic, nws yuav cia li kuaj thiab khiav ib zaug. Qhov kawg taw tes ntawm qhov tseeb ua haujlwm ntawm lub ultrasonic tivthaiv yuav muab khaws cia thiab qhov zaus tam sim no yuav tshwm. Tsim zaus: Ua ntej txiav txim siab kwv yees ntawm zaus ntawm lub tshuab hloov tsheb thiab lub taub hau txiav tawm, thiab tom qab ntawv muab cov zaus kwv yees rau qhov teeb tsa. (Piv txwv li, nws tau kwv yees hais tias qhov hloov ua ke ntawm kev sib xyaw yog li 20KHz, thiab teeb tsa zaus tuaj yeem yog 20 ~ 20.5KHz): Khaws lub sijhawm ua haujlwm tiag tiag, thiab tso saib tam sim no qhov kawg ntawm txhua qhov vuam. Tom qab welding, lub zaus tawm los ntawm cov kub ntawm vuam taub hau lossis lwm yam yog ib txwm nyob hauv lub xeev resonance zoo tshaj plaws thiab khaws cia.
