Ultrasonic yas vuam tshuab vuam tshuab raj
Ultrasonic welding tshuab raj ua lub luag haujlwm tseem ceeb hauv ultrasonic vuam. Tab sis dab tsi" tuam" yog lub tshuab nqus hlau, thiab nws txoj haujlwm yog dab tsi? Cia peb qhia lawv ib tug los ntawm ib qho.
Lub tshuab raj vuam yog ib qho khoom siv uas xa cov kev co mus rau cov yas vuam ib ntu. Nws muaj cov haujlwm nram qab no:
1.Txhais kev siv lub zog tshee
2.Txhais lub zog siab
3.Txhais kev ua haujlwm loj
· Muab cov duab zoo ib yam nrog cov khoom, thiab vim hais tias cov yas yog malleable, nws tuaj yeem haum cov khoom kom txog rau qee yam.
Kev tsim qauv thiab ua haujlwm ntawm lub vuam vias yuav tsum ua tib zoo saib, vim hais tias tsuas yog ib lub vuam hlau zoo tuaj yeem lav qhov ua qhov vuam zoo. Yog hais tias lub vuam tshuab raj tsis zoo tsim (qhov dav dav tsis tsim, tsis tsim nyog kev vibration lub cev), kev tsim khoom tsis zoo (xaiv cov khoom, tsim kho tsis tsim nyog), nws yuav ua rau lub vuam tsoo tawg thiab ua tsis tiav.
Vuam tshuab raj ntawm ntau qhov ntau thiab tsawg
Vuam tshuab raj xaiv xaiv thiab kev txwv
Feem ntau, peb cov ntaub ntawv sib txawv tau siv los ua cov vuam vias, txhua tus ntawm nws muaj nws cov yam ntxwv tshwj xeeb. Xaiv raws li qhov uas yuav tsum ua thiab qhov xav kom ua ntawm kev siv.
1.Aluminium alloy: siv rau cov pwm tsim kom muaj txheej txheem theem lossis me me pob ntau lawm, tsis tuaj yeem tiv taus cov neeg kho tshuab kev ntxhov siab. Los yog rau cov taub hau loj vuam nyob qhov twg hnyav thiab raug nqi yog cov kev txiav txim siab tseem ceeb. Qhov no yog ib qho ntawm cov khoom siv feem ntau, nrog cov khoom siv zoo hauv tshuab (ua haujlwm hardness thiab ultrasonic kev nthuav tawm ceev) thiab kev khwv nyiaj txiag.
2.Titanium alloy: siv nyob rau hauv kev tsim me me, nruab nrab thiab huab hwm coj ntau lawm ntawm cov khoom, muaj cov khoom zoo acoustic, tuaj yeem tiv taus qhov siab tshaj plaws ntawm cov neeg kho tshuab 3 zaug ntawm aluminium alloy, thiab muaj cov coj zoo kuj. Nyob rau tib lub sijhawm, dhau los ntawm kev kho tshwj xeeb saum npoo vuam taub hau tuaj yeem ua rau nws hnav tsis kam ntxiv. Nws feem ntau siv rau vuam plastics uas muaj cov iav fiber.
3.Alloy steel: siv rau vuam yas ntu uas tsis tuaj yeem siv rau aluminium alloy thiab titanium alloy. Nws muaj lub hardness siab thiab siab tshaj qhov hnav tsis kam. Feem ntau, nws yuav tsum tawv ua ntej siv. Cov khoom siv no feem ntau siv hauv ultrasonic hlau ntsia hlau ntsia hlau daim ntaub ntawv.
Txhawm rau kom tau txais qhov zoo tshaj plaws kev vuam ua tiav, nws raug nquahu kom tsis txhob siv cov taub hau loj vuam ultrasonic. Vim hais tias kev co saum toj kawg nkaus qhov loj ntawm cov khoom siv vuam tshuab loj tsis tuaj yeem ua tau zoo ib yam, thaum vuam cov khoom lag luam loj, nws raug nquahu kom siv cov poj niam vuam taub hau lossis sib txuas ntawm ntau tus neeg vuam taub hau. Ua tib zoo mloog cov ntsiab lus nram qab no thaum siv lub taub hau vuam:
1.Txoj kev tsim tawm ntawm aluminium alloy vuam horn≤60μm;
2. Titanium alloy welding horn, rau kev yooj yim vuam vias txuas, qhov tso tawm ntau qhov ntau yog 90-120μm;
3. Rau lub vuam vuam loj, qhov nce ntawm cov zawj ntawm qhov vuam vuam kawg yuav pab kom cov tso tawm dav dav kom ntau yam, thiab qhov loj tshaj qhov tso tawm amplitude tsawg dua 60μm;
4. Rau cov poj niam loj thiab poj niam vuam tshuab raj, qhov ua kom nrov loj ntawm tus poj niam vuam poj niam yog horn40μm;
5. Yuav tsum tau zam kom tsis txhob muaj ntse. Txhua lub vuam ncig ntug yuav tsum sib npaug kom tsis txhob muaj kev puas tsuaj;
6. Cov cuab yeej tsim nyog yuav tsum tau siv txhawm rau sib dhos vuam vuam.
