Qhia kev paub ntxiv: nkag siab txog lub ntsiab cai ntawm ultrasonic vuam nyob hauv ib lub xee thib ob
Ultrasonic vuam siv kev sib nqus loj kawg cov xaim hluav taws xob kis mus rau thaj chaw ntawm ob yam khoom los ua welded. Hauv qab kev kub siab, qhov chaw ntawm ob yam khoom yog rubbed tawm tsam txhua lwm los ua lub fusion ntawm txheej txheej molecular.
Ultrasonic welding siv lub tshuab hluav taws xob ultrasonic los hloov 50/60 Hz tam sim no rau 15, 20, 30 lossis 40 KHz hluav taws xob. Kev hloov pauv ntawm cov tshuab hluav taws xob muaj zog hloov dua mus rau kev hloov ua tshuab ntawm tib qhov hloov mus los ntawm lub tshuab hloov hloov, thiab tom qab ntawd cov lus tsa suab hloov tshuab tau xa mus rau lub taub hau vuam los ntawm kev teeb tsa cov tshuab raj uas tuaj yeem hloov kho qhov nrawm. 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 thaum tshav kub los ntawm kev sib txhuam, uas ua rau thaj chaw ntawm qhov uas yuav tsum tau ua kom sov. Ultrasonic vuam tuaj yeem siv tsis tau tsuas yog cov hlau tsis sib haum thiab tawv tawv siv, tab sis kuj tseem yuav ua cov ntaub thiab cov ua yeeb yaj kiab. Kab lus no tsuas yog qhia ob hom hlau thiab yas vuam.
1) Lub hauv paus ntawm ultrasonic hlau vuam
Lub hauv paus ntsiab lus ntawm ultrasonic hlau vuam yog siv cov tshuab kev co lub zog ntawm ultrasonic zaus (tshaj 16KHz) coj los txuas rau tib hom hlau lossis hlau tsis sib luag. Thaum cov hlau yog ultrasonically welded, tsis yog tus hluav taws xob tam sim no los yog siab kub qhov hluav taws xob tau siv rau qhov chaw ua haujlwm, tab sis nyob rau hauv lub siab zoo li qub, lub zog kev co ntawm lub thav duab tau hloov mus ua kev sib txhuam ua haujlwm, deformation zog thiab txwv kub nce ntawm cov workpieces. Nws yog xim hlau sib txuas ntawm cov pob qij txha yog cov khoom siv khov kho hauv lub xeev uas pom tau tias tsis muaj cov khoom hloov lawm. Yog li, nws ua tiav zoo ntawm qhov txha caj qaum thiab oxidation los ntawm kev tawm tsam vuam. Ultrasonic hlau vuam tshuab tuaj yeem ua tau tib-vuam vuam, ntau qhov chaw vuam thiab vuam luv vuam ntawm cov xov hlau nyias lossis cov ntaub ntawv ntawm cov hlau tsis huv xws li tooj liab, nyiaj, txhuas, thiab npib tsib xee. Nws tuaj yeem siv dav hauv vuam ntawm SCR coj, fuse tej daim, hluav taws xob coj, lithium roj teeb ncej daim, thiab cov tab.
2) Lub hauv paus ntawm ultrasonic yas vuam
Thaum lub nthwv dej ultrasonic ua rau thermoplastic yas sib tiv tauj saum npoo, nws yuav tsim tawm kaum tawm txhiab tus neeg lub siab ua haujlwm nyob rau ib pliag. Qhov no zoo ntawm kev co loj hauv siab nrog qee qhov kev hloov pauv yuav kis tau lub zog ultrasonic mus rau thaj chaw vuam los ntawm kev sib txuas ntawm lub zog sab saud. Vim tias qhov chaw vuam yog ob qho Kev Tshaj Tawm yog qhov loj ntawm qhov vuam interface, yog li qhov ntsuas kub hauv zos yuav tsim tawm. Tsis tas li ntawd, vim muaj qhov tsis zoo thermal conductivity ntawm cov yas, nws tsis tuaj yeem faib nyob rau lub sijhawm ib pliag, thiab nws sib sau rau hauv qhov chaw vuam, ua rau qhov chaw tiv thaiv ntawm ob lub plastics yuav yaj sai, thiab tom qab qee qhov kev thov siab , nws merges rau hauv ib qho. Thaum lub ultrasonic nres, cia lub siab txuas ntxiv rau ob peb feeb kom nws ua kom muaj zog thiab ua kom zoo, kom lub cev muaj zog molecular saw tsim kom ua tiav lub hom phiaj ntawm vuam, thiab lub zog vuam tuaj yeem nyob ze rau lub zog ntawm cov khoom siv raw.
