Cov ntsiab lus ntawm Ultrasonic Welding Parameters
Ultrasonic zaus. Ultrasonic welding sensors yog tsim rau ntau lub nruab thiab daim ntaub ntawv, xws li ntawm 15 mus rau 300 kHz.Feem ntau hlau vuam tshuab yog nyob rau hauv 20 mus rau 40khz, 20 kHz yog tshaj zaus.
Kev vibration amplitude.Qhov kev vibration amplitude ntawm lub taub hau welding yog ncaj qha ntsig txog lub zog xa mus rau lub weld.The amplitude ntawm ultrasonic kev co yog me me ntawm vuam txee - 10,30, los yog 50 microns, tsis tshua muaj siab tshaj 100 microns (li 0.004 nti ) .Nyob rau hauv ib co vuam tshuab, lub amplitude yog ib tug neeg sib txawv ntawm cov neeg saib xyuas; Lwm yam lus, nws tau ua nrog lub hwj huam uas siv rau lub cev.Hauv lwm lub tshuab, qhov sib txawv yog qhov kev hloov ntawm yus tus kheej uas tsim tau thiab tswj tau los ntawm kev tawm tswv yim tswj system nyob rau hauv lub hwj chim.
Static force. Thaum lub vuam vibration pib, qhov sib zog ua hauj lwm ntawm kev ua hauj lwm los ntawm vuam lub taub hau thiab thaiv ib qho kev sib cuag ntawm cov ntxeev lus sab nraud.Qhov loj ntawm qhov quab yuam, nyob ntawm qhov khoom thiab thickness, thiab qhov loj ntawm qhov txuas, kaum tawm txhiab tons rau phav phav cov nyhuv tshiab.Piv txwv li, 40 mm2 weld yog ua nyob rau hauv 6, 000 series ntawm txhuas, nrog ib lub zog ntawm 1, 500 N, thaum lub 10 hli2 vuam ntawm ib daim ntawv muag tooj liab ntawm 0.5 hli tuab tej zaum yuav tsum tau tsuas yog 400n.
Txawm tias tus neeg vuam siv tsis tau, lub zog, lub zog thiab lub sij hawm yog qhov zoo tshaj plaws tshev, lawv muaj kev sib txheeb ze zoo nkaus xwb.Thaum cov kab laug sab, qhov hluav taws xob thiab qhov tam sim no los ntawm lub hwj huam yuav ua rau lub hwj chim ntws mus rau lub transducer thaum lub voj voog .Txhais zog yog qhov chaw nyob hauv vuam vov fais fab.Feem ntau vuam fais fab kev siv nyiaj nyob ntawm lub zog ncov lawv muaj peev xwm muab, xws li ib ntu ntawm ob peb lub tshis rau ob peb kilowatts.Thov ntau lub sij hawm vuam yog tsawg dua ib tus thib ob. tas li cov fais fab tuag, qhov 0.4 vuam thib ob ntawm 2-kw taub hau yuav tsim tawm 800 joules ntawm lub zog.
Cov ntaub ntawv. Qhov no suav nrog ntau cov lus nug thiab tsis muaj feem xyuam nrog ultrasonic hlau vuam.Thaum thawj zaug ua ke ntawm cov ntaub ntawv los yog cov ntaub ntawv.Tej ntawm cov khoom thiab cov khoom siv feem ntau yog xam tau tias yuav ua tau ib qho twg, txawm hais tias kev vuam txwv tsis meej thiab cov ntaub ntawv muaj feem ntau lacking.Qhov cov khoom ntawm cov ntaub ntawv, nrog rau cov qauv, yield zog thiab hardness, yog ib qho tseem ceeb xav.
Feem ntau hais lus, muag tshuaj, txhuas, nickel, magnesium, kub, nyiaj thiab platinum yog cov yooj yim welded nyob rau ultrasonic waves.Harder alloys, xws li titanium, hlau thiab hlau, thiab cov av nkos (nickel-based aviation alloys thiab refactory coals (molybdenum thiab tungsten) yog qhov nyuaj tshaj.
Cov khoom siv deg npoo kuj yog lwm qhov parameter, nrog rau kev kho deg, oxide, txheej thiab cov kab mob.
Geometry. Cov duab ntawm lub vuam feem plays lub luag hauj lwm tseem ceeb, qhov zoo tshaj plaws ua yog lub thickness ntawm qhov chaw.Ntawm, nyias nyias muaj ib tug zoo dua ntawm kev ua tiav kev ultrasonic vuam.Qhov lub thickness ntawm qhov, tshwj xeeb tshaj yog ib feem ntawm qhov sib cuag kis lub taub hau, yuav tsum tau ntau dua qhov chaw vuam lub taub hau, lub zog loj dua qub thiab siab dua vuam siv zog.Qhov siab tshaj plaws muaj nyob ntawm seb muaj lub zog ntawm cov khoom siv thiab lub vias qhov fais fab.
Tool. Lub cuab yeej ua li ntawm ultrasound / vuam taub hau thiab thaiv, siv los txhawb cov khoom thiab xa ultrasonic zog thiab zoo li qub.Nyob rau hauv feem ntau, tooltips tau tiav rau hauv ib lub sonotrode tag nrho tiav, tab sis qee zaum ib tug tshem tau tooltip siv. muaj grooves thiab trench los yog lwm qhov chaw nto roughness los txhim kho workpiece fixtures.
Lub vuam taub hau thiab thaiv thaiv qhov chaw ntim feem ntau yog tiaj tiaj, thiab lub taub hau ntawm lub hau yog tsim kom muaj ib qho me ntsis convex curvature los hloov kev ntxhov siab.
