Ultrasonic Yas Vuam

Kev Taw Qhia

Ultrasonic yas welding tshuab yog fusion velding tshuab. Lub hauv paus ntsiab lus ntawm cov cuab yeej no yog hloov txoj kev sib txhuam thiab kev vibrational mus rau hauv tshav kub. Cov high-zaus kev co generated ntawm lub ultrasonic yog kis tau raws qab siab los ntawm vuam mould (raug xa mus rau lub taub hau lub taub hau) rau kev tivthaiv ua ke, uas ua rau qhov txheeb ze ntawm kev sib koom tes. Kev sib txhuam sov ua rau micro-melting, micro-melting hinders kev co, absorbs co zog thiab converts nws mus rau hauv tshav kub, uas nws thiaj li ua rau cov ntaub ntub dej rau yaj hauv lub sij hawm luv luv, yam ua ib qho kev sib xyaw polymer. Feem ntau, lub vuam profile ntawm lub tog yas yuav tsum welded yuav tsum ua raws li cov kev cai ntawm cov khoom tsim nyog thiab cov seam.

Thaum twg ultrasonically kaw, cov cua sov uas yuav tsum tau tsuas yog ua rau cov thermoplastic sealing txheej. Cov kev hloov no siv tau los ua kom muaj zog, yog li lub sij hawm sib khi tsis ntev heev. Thaum ultrasonically kaw, cua sov yog generated hauv zaj duab xis. Yog li ntawd, nws tsis yog tsim nyog los muab cua sov sab nraud. Cov pwm tseem kub thaum lub vuam txheej txheem. Lub tshav kub generated nyob rau hauv cov khoom yog tsawg kawg. Qhov kub tshuav kub yog qhov ua tiav ntawm lub cab kuj txheej thiab cov txheej txheem sealing. Qhov no tau zoo heev thermal fusion zog.

Ntsug tshuab

Qhov no yog qhov feem ntau hom kev vuam yas siv ultrasonics. Feem ntau, tag nrho cov vuam kab yog longitudinally dlhos, thiab lub vibration yog thov longitudinally mus rau workpiece; lub siab tsim los ntawm lub tog raj kheej thawb lub welding ncej ntawm tag nrho lub zog kom yuam cov workpiece mus rau txheej txheej.

Torsion txheej txheem

Lub kaw lus no kuj yog ib txoj kab ntsug tag nrho, tab sis txoj kev vuam yog txawv txav. Txoj kev no yog qhov sib txhuam ntawm kev sib txhuam ntau. Daim ntawv thov ntawm kev vam meej tangential: Lub vuam lub taub hau tsiv ntawm lub siab thiab sab workpieces. Qhov siab vibration zaus (20 kHz), qhov siab thiab siab ua rau lub sijhawm ua haujlwm ntawm ob txoj haujlwm vim kev sib txhuam.

Daim ntawv thov ntau

Ultrasonic yas welding yog peev xwm ntawm welding tag nrho cov thermoplastics. Ntawm cov ntawv tshwj xeeb yog qhov sib txuam ua ke ntawm cov khoom sib txawv ntawm cov ntoo crystalline los sib tshuam crystalline hom sib txawv.

Lub welded qauv nyob rau hauv lub longitudinal thiab torsional txoj kev yog txawv kiag li.

Ultrasonic welding tau txuas ntau hom thermoplastics (amorphous yas) rau qee qhov twg, tab sis ultrasonic vuam yog tsis haum rau vuam thermoset plastics.

Niaj hnub no, ultrasonic welding tau dav siv nyob rau hauv kev lag luam plastics kev lag luam.
