Cov teb ntawm kev siv hauv kev lag luam ultrasonic welding tshuab kev lag luam
Hauv kev tsim cov khoom lag luam kev lag luam, qee yam khoom siv kev lag luam feem ntau yog siv, xws li yas, hlau, ntoo thiab lwm yam khoom lag luam. Hauv lub neej txhua hnub, peb feem ntau pom tias ib cov khoom tsim muaj nrog ntau dua ib hom khoom siv; peb kuj pom ntau zaus Thaum ib qho khoom sib koom ua ke ntawm ntau qhov chaw, thiab yuav muaj qhov khoob ntawm qhov seem, qhov no yuav tsis tsuas cuam tshuam cov khoom zoo, tab sis kuj cuam tshuam rau kev zoo nkauj ntawm cov khoom. Qhov no xav kom lawv yuav tsum tau welded rau txhua lwm yam. Ua raws li kev txawj ntse Nrog kev txhim kho, neeg' s xav tau rau kev vuam kev ua tau zoo dua thiab siab dua. Tam sim no, cov kev siv vuam vias ib txwm tsis yog tsuas yog kim, tab sis qhov zoo ntawm vuam tsis yog qhov siab, thiab cov voos hloov maj mam tshwm sim ntau. Yog li no, tib neeg cia siab siv cov tshuab tshiab vuam ultrasonic vuam los txhim kho cov khoom lag luam. Zoo. Muab los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Kawm ntawm Shanghai Huangrun Ultrasonic Technology Co., Ltd.
Xyoo 1943, raws li kev suav txog cov kev kwv yees yav dhau los thiab cov kev coj ua, Behl hauv Tebchaws Meskas tau tsim lub tshuab nqus hlau ultrasonic, uas tau pib txij li kev txhim kho ntawm cov kev siv ultrasonic vuam. Vim tias cov kev siv vuam vias ultrasonic yog cov kev txuag hluav taws xob, tsis tas yuav tsum nruab cov pa hluav taws xob tso hluav taws xob, thiab tsis muaj lub vuam txuas ntxiv yuav tsum muaj thaum vuam. , Tsawg tus nqi, kev ua haujlwm siab, kev sib khi zoo, yooj yim rau kev paub tsis siv neeg ntau lawm thiab lwm yam zoo, qhov kev siv vuam ultrasonic tau tsim kho sai thiab nrawm dua.
1. Cov xwm txheej tam sim no ntawm kev siv ultrasonic welding kev txawj hauv cov khoom lag luam
Hauv cov teb ntawm aerospace, kev lag luam nuclear hluav taws xob, kev lag luam hluav taws xob thiab lwm yam kev lag luam nrog qhov siab yuav tsum tau, nws tsis yooj yim kom tau raws li cov txheej txheem kev siv kev siv vuam vuam siv, thiab tus nqi siab thiab qhov ua haujlwm tsawg. Tam sim no, cov kev siv vuam ultrasonic siv rau txhua qhov chaw ntawm lub neej. Txhua tus tau siv zoo, xws li kev kho mob tshuab, ntim khoom, kho vajtse thiab lwm yam haujlwm; muaj ntau cov khoom lag luam uas tuaj yeem txuas tau, xws li pib ntu, kho qhov muag iav, U disks, thiab lwm yam.
2. Cov ntsiab cai thiab cov yam ntxwv ntawm kev siv vuam ultrasonic
Ultrasonic yog lub suab sib chwv nrog lub zaus siab dua 20000 Hz, yog li lub zog loj. Ultrasonic vuam yog vuam tshwj xeeb uas siv cov neeg kho tshuab oscillation lub zog ntawm ultrasonic zaus (ntau dua 20000 Hz) los txuas tib yam lossis tsis sib luag ntawm cov hlau, cov khoom siv hluav taws xob, plastics, thiab cermets. Txujci [1]. Thaum ultrasonic vuam ua rau saum npoo ntawm thermoplastic plastics, kaum tawm txhiab tus hauv siab ua hauj oscillations ib ob yuav tshwm sim. Qhov no ntawm high-zaus oscillations mus txog qee yam amplitude yuav xa cov hluav taws xob ultrasonic mus rau thaj chaw welding los ntawm kev sib txuas sab sauv. Qhov chaw vuam, uas yog, lub suab sab saum toj ntawm lub interface ntawm ob lub vuam yog qhov loj, yog li qhov ntsuas kub hauv cheeb tsam yuav tshwm sim. Thiab vim tias qhov tsis zoo thermal conductivity ntawm cov khoom lag luam yas, lub zog ua ke tsis tuaj yeem tawm nyob rau hauv lub sijhawm ib pliag, yog li lub zog yuav sib sau ua ke rau thaj chaw vuam, ua rau ob qhov chaw sib tiv tauj ntawm cov yas yaj sai, thiab tom qab qee qhov nqi ntawm siab thov, nws yuav fuse rau hauv ib qho. Thaum lub ultrasound nres, cia lub siab txuas ntxiv rau ob peb feeb kom ua kom muaj zog thiab zoo, yog li tsim txoj saw hlau muaj zog. Yog li thiaj li ua tiav lub hom phiaj ntawm vuam. Thaum cov hlau yog ultrasonically welded, tsis yog qhov tam sim no xa mus rau qhov chaw ua haujlwm los yog qhov siab kub qhov chaw tau siv rau lub workpiece, tab sis nyob rau hauv kev ua zoo li qub siab, lub zog elastic oscillation hloov mus rau hauv kev sib txhuam ua haujlwm ntawm qhov workpiece interface, Lub zog deformation thiab qhov kub tsis tshua muaj qhov kub nce ntxiv ua cov hlau atoms hauv qhov chaw vuam siv tam sim, thiab cov lwg me me ntawm ob-theem interface nkag mus rau ib leeg, thiab thaum kawg paub qhov tseeb lub xeev txuas ntawm cov hlau txuas.

2.1 Muaj zog ntawm cov txuj ci ultrasonic welding
Piv nrog rau kev vuam viav vias ib txwm muaj, kev paub vuam ultrasonic muaj qhov zoo li hauv qab no: (1) Kev vuam vuam nrawm nrawm, vuam raug qhov siab, thiab siab vuam sib koom ua ke; (2) Kev ua haujlwm vuam dav, muaj kev ruaj khov zoo, thiab me deformation ntawm qhov haujlwm tom qab vuam; (3) Qhov saum npoo ntawm cov khoom siv vuam yog huv thiab zoo nkauj, du thiab du; (4) Thaum vuam, tsis muaj tus neeg saib xyuas vuam yog qhov xav tau, uas yuav tsis ua kom lub cev ua haujlwm thiab ua kom tsis muaj pa phem, yog li nws yog ib puag ncig tus phooj ywg vuam; (5) Thaum vuam, tsuas yog yuav tsum tau muab cov hwj huam me me kom ua vuam, siv zog tsawg; (6) Kev lag luam yooj yim, tus nqi qis, kev ua haujlwm siab, thiab kev sib khi zoo.
