1.Lub hauv paus ntsiab lus thiab cov yam ntxwv ntawmultrasonic yas welder
Raws li cov khoom siv thermal sib txawv ntawm cov resin, cov yas tuaj yeem muab faib ua cov thermoplastics thiab thermosetting plastics.Ultrasonic yas vuam tshuab tuaj yeem tsuas yog vuam cov thermoplastics.
1.1 Lub hauv paus ntsiab lus thiab cov cuab yeej ntawm ultrasonic yas welder
Lub hauv paus ntsiab lus ntawm ultrasonic yas welder: Ultrasonic yas vuam yog ib hom kev siv tshuab uas melts thiab sticks ib feem ntawm cov yas welds ua ke nyob rau hauv qhov kev txiav txim ntawm ultrasonic kev co.
Cov khoom tseem ceeb ntawm ultrasonic yas vuam tshuab zoo ib yam li ultrasonic hlau vuam tshuab, uas yog tsim los ntawm ultrasonic generator & system, tshuab lub cev thiab lub ultrasonic horn.Nws muaj xws li tsis siv neeg zaus mus txog qhovtwg, amplitude tswj system thiab lub sij hawm tswj system thiab ib co vuam hom system.
1.2 Cov yam ntxwv ntawm ultrasonic yas vuam tshuab
(1) Tsis zoo li qhov khoov kev vibration yuav tsum tau los ntawm ultrasonic hlau vuam, Lub longitudinal kev co yog ncaj qha mus rau lub vuam cheeb tsam los ntawm lub Upper ultrasonic horn, thiab kev co kev taw qhia ntawm lub ultrasonic horn yog perpendicular mus rau qhov chaw ntawm lub vuam ib feem.Vim lub suab tsis kam ntawm qhov chaw sib cuag ntawm ob lub welds (xws li vuam cheeb tsam), lub zos kub yuav raug tsim.Vim yog qhov tsis zoo thermal conductivity ntawm cov yas, cov cua sov tsis yooj yim rau disperse thiab sib sau ua ke nyob rau hauv qhov chaw vuam, yog li ntawd cov yas melts.Nyob rau hauv txoj kev no, nyob rau hauv qhov kev txiav txim ntawm kev sib cuag tsis tu ncua, qhov sib cuag ntawm qhov chaw vuam melts mus rau hauv lub cev, thiab tom qab kho, qhov chaw vuam lossis vuam nto tuaj yeem tsim.
(2) Thaum lub sij hawm vuam txheej txheem, vim hais tias lub zog ultrasonic kev co yog kis mus rau lub vuam cheeb tsam los ntawm lub Upper ultrasonic horn, qhov kev ncua deb ntawm ultrasonic vibration zog yog txawv nrog cov duab ntawm lub Upper ultrasonic horn.Raws li qhov kev ncua deb ntawm lub ntsej muag radial kawg ntawm lub tshuab raj ultrasonic mus rau qhov chaw vuam, nws tau muab faib ua ze rau qhov chaw vuam thiab qhov chaw nyob deb vuam.Feem ntau, qhov kev ncua deb li ntawm 6 ~ 7 hli yog hu ua ze qhov chaw vuam, thiab qhov kev ncua deb tshaj qhov no yog hu ua far field welding.
(3) Ultrasonic yas vuam yog txawv ntawm hlau vuam, tus yuam sij ntawm ultrasonic yas vuam yog tsim ntawm vuam chaw thiab vuam horn.Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov yas vuam ultrasonic, nws yog ib qho tsim nyog los xaiv qhov tsim nyog lub zog ultrasonic, vuam siab thiab vuam lub sij hawm, thiab cov qauv tsim ultrasonic horn.
