Kev yuam kev thaum them sai sai rau Ultrasonic Vuam
Ultrasonic vuam tshuab yog qhov yuav tsum tau ua rau cov khoom siv tau welded, tsis yog txhua cov ntaub ntawv tuaj yeem txuas tau. Qee tus neeg nkag siab tias txhua yam ntaub ntawv tuaj yeem tuaj yeem yog hlau, uas yog qhov yuam kev loj heev. Qee hom ntaub ntawv tuaj yeem ua tau zoo dua welded, qee qhov tseem tuaj yeem fuse, thiab qee qhov tsis yaj. Lub ntsiab lus melting ntawm cov khoom siv tib yam, thiab lub hauv paus ntsiab lus yog tias nws tuaj yeem txuas tau, tab sis thaum lub ntsiab lus melting ntawm lub workpiece yuav tsum tau welded yog ntau dua 350 ° C, nws tsis haum rau ultrasonic welding. Vim tias lub ultrasonic tam sim no yog lub caij yaj kom cov yaj ua haujlwm cov haujlwm, cov kev txiav txim siab yog ua raws 3 vib nas this, thiab tsis tuaj yeem muab welded zoo, lwm cov txheej txheem vuam yuav tsum tau xaiv. Xws li kub phaj vuam. Feem ntau hais lus, ABS cov khoom yog qhov yooj yim tshaj plaws rau weld, thiab nylon yog qhov nyuaj tshaj plaws rau weld. Coob tus naj npawb ntawm cov neeg koom nrog ultrasonic vuam rau ntau xyoo muaj kev nkag siab yuam kev txog kev xa kis ntawm ultrasonic zog. Nws ntseeg tau tias lub suab nrov tau welded rau ntawm lub chaw tiv tauj. Qhov tseeb, qhov tseeb txoj hauv kev welding yog: tom qab tus hloov pauv hloov hluav taws xob lub zog rau hauv tshuab, nws dhau los ntawm cov khoom siv molecules ntawm lub workpiece. Kev ua kom yooj yim, lub suab tsis kam ntawm suab nrov hauv khib nyiab yog me dua li uas hauv cov huab cua. Thaum lub suab ntog dhau ntawm cov pob qij txha ntawm cov khoom ua haujlwm, lub suab tsis kam hauv qhov sib txawv yog qhov loj, thiab lub zog cua sov tsim tau loj heev. Qhov kub ua ntej tau mus txog qhov chaw yaj ntawm cov haujlwm tawm, ntxiv rau qee qhov siab los txuas weld lub leeg. Lwm feem ntawm qhov chaw ua haujlwm tsis tau vim tsis muaj cua sov ua haujlwm tsis tshua zoo thiab ntsuas kub. Lub hauv paus ntsiab lus zoo ib yam li Ohm txoj cai hauv kev tsim hluav taws xob.
