Qhov sib txawv ntawm ultrasonic hlau hlau thiab yas vuam
Tsis ntev tas los no, ntau tus phooj ywg tau nug txog cov ntsiab cai thiab qhov sib txawv ntawm ultrasonic yas vuam thiab cov hlau hlau. Txhawm rau kom cov neeg siv to taub qhov sib txawv, tus sau txheeb cais vuam cov ntsiab lus thiab qhov sib txawv ntawm ultrasonic yas thiab hlau vuam tshuab.
1. Ultrasonic tshuab vuam tshuab
Thaum ultrasonic tsis ua rau thermoplastic tiv tauj qhov chaw, nws ua kom muaj phav phav qhov kev tsuj hluav taws xob txhua qhov thib ob. Qhov kev ntsuas siab loj no nce mus txog qee qhov kev hloov pauv thiab xa cov zog ultrasonic mus rau qhov chaw vuam mus txog rau sab qaum kev siv vuam. Vim tias qhov chaw vuam, uas yog, lub suab rwb thaiv tsev ntawm ob chav vuam cuam tshuam, yuav tsim kom muaj qhov kub thiab txias hauv zos. Vim tias cov thermal ua tsis zoo ntawm cov yas, lawv tsis tuaj yeem faib nyob rau hauv ib lub sijhawm thiab sib sau ua ke rau thaj chaw vuam, ua rau thaj chaw sib tiv thaiv ntawm ob lub plasma yuav yaj sai, thiab ib qho siab ntxiv ntxiv rau qhov sib xyaw ua ke Cov. Thaum lub ultrasonic nres, cia lub siab txuas ntxiv mus li ob peb feeb kom nws ua kom muaj zog, thiaj li tsim lub zog muaj zog lub zog kom ua tiav lub hom phiaj ntawm vuam, thiab lub zog vuam tuaj yeem nyob ze rau lub zog ntawm cov khoom siv raw. Qhov zoo ntawm ultrasonic yas vuam nyob ntawm qhov muaj ntau ntawm cov welded sib koom tes ntawm qhov hloov pauv, ntxiv kev kub siab thiab lub sijhawm vuam. Lub sijhawm vuam thiab vuam taub hau siab tuaj yeem hloov kho, thiab qhov dav txiav txim tau txiav txim siab los ntawm transducer thiab amplitude bar. Kev sib cuam tshuam ntawm qhov peb muaj nuj nqis no muaj tus nqi tsim nyog. Thaum lub zog ua tus nqi tshaj qhov tsim nyog, tus nqi ntawm cov yas melting yog loj thiab cov khoom vuam yooj yim deformed; thaum lub zog tseem me, nws tsis yooj yim rau weld thiab lub siab tsis loj dhau. Qhov ntsuas siab zoo no yog cov khoom ntawm sab ntev ntawm qhov txuas ntawm welded thiab qhov siab zoo rau ib 1 hli ntawm sab.
2. Ultrasonic cov hlau txuas
Lub hauv paus ntsiab lus ntawm ultrasonic hlau vuam yog cov qauv tshwj xeeb uas siv cov tshuab kev co zog ntawm ultrasonic zaus (tshaj 15KHz) txuas cov tib hlau lossis hlau tsis sib luag. Thaum ultrasonic vuam hlau, tsis yog lub zog hluav taws xob tam sim no los tsis kub lub qhov cua sov yog siv, tab sis nyob rau hauv lub zog zoo li qub, lub zog ntawm lub tshuab xaim hlua hloov mus rau hauv kev sib txhuam ua haujlwm, deformation zog thiab txwv kub nce ntawm cov workpieces. Kev sib xyaw ntawm cov xim hlau sib txuas ntawm cov pob qij txha yog cov khoom siv khov kho uas tsis yaj lub hauv paus cov khoom, uas tuaj yeem kov yeej qhov txaws thiab oxidation qhov tshwm sim los ntawm kev ua haujlwm tsis vuam. Ultrasonic hlau vuam tshuab tuaj yeem ua qhov chaw vuam, ntau qhov chaw vuam thiab vuam luv ntawm cov hlau tsis muaj hlau tsis muaj hlau lossis cov ntawv siv xws li tooj liab, nyiaj, txhuas, thiab npib tsib xee. Nws tuaj yeem siv dav rau vuam thyristor ua, fuses, hluav taws xob ua, lithium roj teeb electrodes thiab pob ntseg.
