1.Xyooj
Tus txheej txheem ua haujlwm ntawm ultrasonic yas vuam tshuab: siv ultrasonic kev co zaus, kev sib tiv tauj ua kom muaj cua sov ua kom yaj thiab ua ke yas. Raws li qhov tam sim no, nws yog 20,000 zaug ib pliag (20 kHz) thiab 15,000 deeg ntawm ib pliag (Muaj ob yam tshwj xeeb kev co zaus, 15 kHz. Vim tias qhov chaw tsis tshua muaj, tsuas yog ob qho kev sib txuam ntawm 15 kHz thiab 20 kHz ua tswvcuab.
Txoj kev tuaj yeem muab faib ua vuam sib txuas thiab coj mus txuas rau ob txoj hauv kev vuam.
Kev siv ncaj qha vuam: thawj tsim cov khoom siv xws li kab lossis txoj siv sia sib tshooj sib xws (xws li, riveting, embedding, thiab lwm yam), tsau rau ntawm lub tshuab ultrasonic yas vuam tshuab, cia nws lub zog hluav taws xob (HORN) ncaj qha ua kom muaj suab nrov kev co thiab vuam.
Kev sib txuas hauv vuam: uas yog, thaum vuam, nws sib cais los ntawm ultrasonic kev co, thiab sib cais los ntawm qhov deb, thiab kis tau los ntawm nws cov ultrasonic kev co (piv txwv li, plhaub yas vuam, thiab lwm yam).
2.Fooj
A. Nws tuaj yeem tau txuas rau thermoplastic plastics uas tsis yog Teflon.
B. Lub sijhawm vuam vuam luv yog luv heev, feem ntau li ntawm 0.5 thib ob txog 1 thib ob.
C. Nws tuaj yeem tau txuas rau qhov sib koom ua ke ntawm qhov nruab nrab xws li dej, roj lossis lwm yam.
D, vuam nyhuv, txog qib uas ua tau.
E, tuaj yeem ncaj qha rau welded rau kev coj ua.
F. Lub zog vuam ntawm cov khoom tuaj yeem sib txawv raws li cov khoom siv yas, thiab nws tsis yog txhua cov ntaub ntawv ntawm ultrasonic kev co. Tsuas yog qhov tsim nyog nto kev co yog xaiv los ua kom muaj cua sov, yog li tsis muaj kev txhawj xeeb txog saum npoo ntawm cov khoom, uas yog tus yam ntxwv ntawm kev ua haujlwm vuam. Thaum cov yas nyuaj ntawm welded, lub vuam nyhuv tuaj yeem ua rau ntau qhov sib zog.
G.Ultrasonic vuam tsis ua rau muaj kuab lom xws li tshuaj lom neeg cov tshuaj, thiab yog txoj kev ua haujlwm vuam ruaj ntseg.
3.Application
Cov ntawv thov ultrasonic yog qhov dav heev, thiab peb feem ntau paub zoo siv nyob rau hauv cov tshuaj. Hauv thaj chaw muaj kev lag luam, txhua tus neeg tuaj yeem siv lawv tus kheej cov khoom lag luam, lossis tuaj yeem nrhiav tau tias ultrasonic kuj tseem nyob hauv qhov kev txiav txim siab ntawm lawv tus kheej cov khoom, tso cai rau ultrasound los txhim kho koj qhov kev ua tau zoo thiab zoo. Nws tseem yuav yog qhov peb ib txwm xav tau.
Cov uas tau txais ntawm daim ntawv thov:
1, vuam; 2, cog ntoo; 3, txoj kev ua; 4, riveting; 5, nqaij ntawd vuam;
6, kev co (txiav); 7, kub yaj.
Tsuas yog txais khoom rau khoom thib xya, uas yog ultrasonic hloov vuam, qhov seem yog qhov tseem ceeb ua haujlwm ntawm ultrasonic nthwv dej.
