Lub tshuab nqus hlau sib txawv muaj cov haujlwm sib txawv thiab lawv tus kheej cov yam ntxwv hauv kev ua haujlwm thiab siv. Tus kws sau xov xwm xav tias qhov tseem ceeb ntawm lub tshuab vuam nyob hauv nws txoj haujlwm ua haujlwm. Nws muaj peev xwm txuas ntxiv kom nkag siab txog kev ua haujlwm ntawm lub tshuab vuam thiab tag nrho kev ua haujlwm. Nov yog qhov txuas txuas ntxiv. Txhua tus neeg xav paub ntxiv rau ultrasonic yas vuam tshuab thiab hlau vuam tshuab. Kuv yuav piav qhia qhov sib txawv ntawm ob lub tshuab welding no.
1. Ultrasonic tshuab vuam tshuab
Thaum ultrasonic vuam ua rau thermoplastic tiv tauj saum npoo, nws tsim kom muaj phav phav tus tsaj tsaws tsaj ua rau txhua ob. Qhov kev ntsuas siab loj no nce mus txog qee qhov ntau, thiab lub zog ultrasonic kis mus rau thaj chaw ntawm vuam mus los ntawm qhov chaw vuam sab saud. Vim tias qhov chaw vuam, uas yog, lub suab rwb thaiv tsev ntawm ob lub vuam kev cuam tshuam, kub hauv zos yuav tsim tawm. 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, hloov siab ntxiv thiab lub sijhawm vuam. Lub sijhawm vuam thiab vuam taub hau siab tuaj yeem hloov kho, thiab qhov txawv txav tau txiav txim siab los ntawm qhov 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 siv vuam yog yooj yim rau deform; thaum lub zog tseem me, nws tsis yooj yim los 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 qhov qauv tshwj xeeb uas siv cov tshuab kev co lub 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 kev co ntawm cov hlua hlau hlua tau hloov mus ua kev sib txhuam ua haujlwm, deformation zog thiab txwv kub nce ntawm cov workpieces. Cov xim hlau sib txuas ntawm cov pob qij txha yog cov khoom siv lub xeev tsis ruaj khov uas tsis yaj lub hauv paus cov khoom siv, uas tuaj yeem kov yeej qhov txaws thiab oxidation qhov tshwm sim los ntawm kev ua haujlwm tsis vuam. Ultrasonic hlau tsis muaj peev xwm ua tau ib qho 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, npib tsib xee thiab lwm yam. Nws tuaj yeem siv dav rau vuam thyristor coj, fuses, hluav taws xob ua, lithium roj teeb electrodes thiab pob ntseg.
Muaj ntau qhov sib txawv ntawm cov tshuab yas hlau thiab tshuab hlau tshuab, nrog rau kev ua haujlwm, cov khoom siv pwm, thiab cov hauv paus ntsiab lus ua haujlwm. Cov khoom uas lawv txuas nrog koom nrog ntau daim teb, thiab nws yog ib qho tsim nyog kom nkag siab txog lub tshuab vuam tshuab kom meej.
