Ultrasonic pwmyog ib qho tseem ceeb tshaj plaws ntawm ultrasonic technology.Txawm tias muaj ntau xyoo ntawm kev tsim thiab kev tsim kho, peb ntseeg tau tias tsuas yog los ntawm kev sim nruj thiab kev tswj kom zoo tuaj yeem tsim tau qhov zoo tshaj plaws vuam taub hau.Peb cov engineers yuav welding cov yam ntxwv acoustic thiab cov neeg kho tshuab cov yam ntxwv ntawm kev sib xyaw ua ke zoo tshaj plaws, tsim qhov zoo tshaj plaws nyob rau hauv txoj kab nrog cov neeg siv khoom xav tau ntawm cov khoom, ultrasonic pwm yog ib qho tseem ceeb parameter, ultrasonic pwm amplitude tsis tseem ceeb heev hauv kev xyaum!
Lub amplitude parameter tsim ntawm pwm: amplitude yog ib qho tseem ceeb parameter rau cov khoom uas yuav tsum tau welded, uas yog sib npaug rau qhov kub ntawm ferrochrome.Yog tias qhov kub tsis tuaj yeem ncav cuag nws, nws yuav tsis raug fused.Yog tias qhov kub thiab txias dhau lawm, cov khoom siv raw yuav scorched los yog ua rau cov qauv kev puas tsuaj thiab lub zog yuav deteriorate.Vim qhov kev xaiv sib txawv ntawm cov transducer sib txawv, qhov amplitude ntawm lub transducer tso zis tom qab haum qhov sib txawv ntawm qhov sib txawv ntawm qhov amplitude thiab vuam taub hau, muaj peev xwm ua hauj lwm kho ntawm vuam taub hau amplitude kom ua raws li qhov yuav tsum tau, feem ntau transducer tso zis amplitude rau 10-20. microns, thiab kev ua haujlwm amplitude, feem ntau txog 30 microns, thiab amplitude hloov ntawm vuam taub hau dua nrog lub amplitude thiab cov duab ntawm lub vuam taub hau, Raws li cov duab, xws li exponential amplitude variation, functional amplitude variation, ntaiv amplitude variation, thiab lwm yam, nws muaj kev cuam tshuam zoo rau qhov sib txawv ntawm qhov sib txawv, thiab thaj tsam piv yog proportional rau tag nrho cov variation ratio.Yog tias cov welder sib txawv raug xaiv, txoj kev yooj yim tshaj plaws yog ua kom lub vuam taub hau nyob rau hauv kev faib ua feem rau qhov loj ntawm kev ua hauj lwm, uas tuaj yeem ua kom muaj kev ruaj ntseg ntawm qhov amplitude tsis.
Zaus parameter tsim: Ultrasonic vuam tshuab tag nrho muaj lub hauv paus zaus, xws li 20KHz, 40khz, thiab lwm yam. Kev ua hauj lwm zaus ntawm lub vuam tshuab yog txiav txim siab los ntawm cov neeg kho tshuab resonance zaus ntawm Transducer, Booster thiab Horn.Qhov zaus ntawm Ultrasonic generator yog hloov raws li cov neeg kho tshuab resonance zaus kom ua tau raws li qhov sib xws.Lub taub hau vuam ua haujlwm hauv lub xeev resonant, thiab txhua qhov yog tsim los ua ib nrab wavelength resonant lub cev.Ob lub tshuab hluav taws xob thiab cov tshuab hluav taws xob resonance zaus muaj qhov ua haujlwm resonant, xws li feem ntau teem rau ± 0.5khz, nyob rau hauv qhov ntau yam vuam tshuab tuaj yeem ua haujlwm ib txwm.Thaum ua txhua lub taub hau vuam, qhov zaus resonant yuav raug hloov kho kom ntseeg tau tias qhov kev ua yuam kev ntawm lub resonant zaus thiab qhov tsim zaus tsawg dua 0.1khz, xws li 20KHz vuam taub hau, zaus ntawm lub vuam taub hau yuav raug tswj ntawm 19.90-20.10. khz, qhov kam rau ua yog 5% .
Pwm vibration node tsim: ultrasonic vuam lub taub hau thiab lub horn yog tsim los ua ib nrab-wavelength resonant lub cev nrog ib tug ua hauj lwm zaus.Hauv lub xeev ua haujlwm, qhov amplitude ntawm ob lub ntsej muag kawg yog qhov siab tshaj plaws thiab qhov kev ntxhov siab yog qhov tsawg kawg nkaus, thaum lub amplitude ntawm node sib raug rau qhov chaw nruab nrab yog xoom thiab qhov kev ntxhov siab yog siab tshaj.Kev tsim qauv dav dav rau qhov chaw ruaj khov, tab sis feem ntau qhov chaw ruaj khov ntawm cov qauv tsim thickness ntau dua 3 hli, lossis zawj yog tsau, yog li qhov chaw ruaj khov tsis tas yuav yog xoom amplitude, qhov no yuav ua rau qee qhov kev hu, thiab ib feem ntawm lub zog. poob, rau lub suab feem ntau nrog lub nplhaib roj hmab nrog rau lwm qhov, los yog nrog cov ntaub ntawv rwb thaiv tsev rau kev tiv thaiv, lub zog poob yog coj mus rau hauv tus account nyob rau hauv tus tsim ntawm tuag amplitude tsis.
Pwm machining precision tsim: ultrasonic vuam lub taub hau rau kev ua hauj lwm nyob rau hauv lub siab zaus vibration xwm txheej, yuav tsum tau sim kom ib tug symmetrical tsim, thiaj li tsis txhob acoustic hloov los ntawm lub asymmetry ntawm unbalanced kev nyuaj siab thiab transverse vibration (welding lub taub hau yog siv rau vuam los ntawm kev siv. lub ultrasonic kev co ntawm ntsug kis tau tus mob, rau lub resonant system), lub unbalance kev co yuav ua rau vuam kub plaub hau thiab puas.Ultrasonic welding yog siv nyob rau hauv ntau industries yog txawv rau machining precision yuav tsum tau, rau tshwj xeeb nyias artifacts xws li lithium ion roj teeb ncej ncej thiab pob ntseg ntawm vuam, xws li cov ntawv ci kub npog qhov yuav tsum tau ntawm machining raug yog heev, tag nrho cov ua. cov cuab yeej siv cov cuab yeej tswj cov lej (xws li machining center, thiab lwm yam), thiaj li yuav lav tau qhov kev ua tau zoo raws li qhov yuav tsum tau ua.
