Cov hauv paus ntsiab lus thiab qhov zoo ntawm ultrasonic handheld spot vuam tshuab
Ultrasonic spot vuam tshuab ua tau tiag rau qeb ntawm ultrasonic vuam. Nws siv ultrasonic vuam los ua kom loj-ua kev co mus rau weld ob cov ntaub ntawv, hlau lossis yas, ua ke. Rau qhov kub-qhov tsim yam tsis muaj cov khoom sib dhos, lossis qhov chaw uas muaj cov duab geometry thiab cov xwm txheej tseeb tsis suav nrog kev ua haujlwm ntawm vuam kev ua haujlwm, ultrasonic chaw vuam yog qhov tsim nyog rau kev ua.
Hnov vuam yuav siv tau rau ultrasonic muaj zog vuam ntawm cov ntawv yas muag muag xws li ABS, polyethylene, polypropylene, thiab PVC. Lub phiaj xwm tshwj xeeb uas tsim los siv lub taub hau yog siv los txhim kho lub vuam lub zog thiab cov tsos. Ultrasonic spot welding hloov cov nplaum, rivets, staples thiab lwm yam neeg kho tshuab fasteners. Cov txheej txheem no yog siv los sib sau ua ke trailer lub cev, kho tsheb cov raj roj lim, rooj tog thiab lwm qhov chaw loj thermoplastic. Siv cov cuab yeej siv tes ua tau yooj yim thiab lub tshuab siv ntau lub taub hau, ntau lub welds tuaj yeem ua rau tib lub sijhawm.
Ntsiab Cai ntawm Vuam
Ultrasound yog cov neeg kho tshuab kev co, zoo ib yam li kev vibration uas tsim los ntawm cov twj paj nruag. Cov kev co no yog hu ua ultrasonic tsis tau vim tias lawv cov zaus raug siab dua tib neeg lub rooj sib hais (ntau dua 16 kHz). Hauv lub ntsiab lus acoustic, cov xaim hluav taws xob no tau tsim los ntawm lub tshuab hluav taws xob. Qhov no yuav xa cov hloov tam sim no ntawm tib zaus uas yog hloov dua siab tshiab (lossis hloov dua tshiab). Tom qab ntawd, lub tshuab xa hluav taws xob ua los ntawm piezoelectric ceramics hloov lub zog no mus rau kev siv tshuab kev co. Tom qab ntawd, cov neeg kho tshuab kev co yuav ua rau muaj kev sib txhuam thermal, uas yuav txhawb lub molecules ntawm cov khoom raug welded kom pib txav. Lub zog hluav taws xob yuav yaj ua lub ntsiab lus sib tiv tauj ntawm ob ntu, yog li sib koom ua ke, cia qhov ntawm cov lus sib txuas tau sai.
Qhov tshuab vuam siv zog yog tsim nyog rau cov cheeb tsam uas tsis tas yuav tsum txuas rau tag nrho cov vuam taug kev tib lub sijhawm. Nws yog lub teeb hauv qhov hnyav thiab yooj yim siv, thiab tuaj yeem siv rau sab nraum zoov. Hnov vuam tshuab muaj qhov siab tshaj, hloov tau yooj yim thiab raug nqi, yog li nws tseem muaj qhov sib tw muaj zog ntawm ntau yam vuam teb.
Vuam zoo
Vuam cov txheej txheem: Kev soj ntsuam ultrasonic vuam mus txog lub sijhawm, lub zog, lub zog thiab qhov siab, thiab qhov tseeb-lub sijhawm nrhiav tag nrho cov txheej txheem vuam txhawm rau ua kom zoo ntawm tag nrho cov txheej txheem welding thiab txo lub zog siv ntawm ntau lawm.
Kev txuag tus nqi thiab kev tiv thaiv ib puag ncig: tag nrho cov txheej txheem vuam yog huv thiab tsis muaj kuab paug, vim tias cov kuab tshuaj tsis zoo lossis cov nplaum yuav tsis siv thaum lub sijhawm vuam, thiab cov khoom nws tus kheej yuav tsis puas, zam qee qhov teeb meem ntawm kev siv vuam ib txwm thiab cov txheej txheem sib khi, Txuag welding nqi. Vim tias nws muaj hluav taws xob ua tiav, cov thev naus laus zis no tsis tas yuav tsum muaj kev tu qib siab.
Ceev: Lub voj voos raug vuam yog nyob hauv 0.5 vib nas this. Piv nrog rau lwm txoj kev vuam, vuam nrawm dua. Cov txheej txheem vuam no yog nrawm dua li cov tshuaj pleev ib ce lossis cov kuab tshuaj. Lub sijhawm txias yog qhov nrawm heev, thiab qhov chaw ua haujlwm tsis tas yuav tsum muab tso rau hauv lub cuab yeej rau sijhawm ntev kom qhuav lossis tawv ntawm qhov sib txuas welded.
Kev siv tau yooj yim: Qhov dav dav ultrasonic chaw vuam tshuab lossis chaw vuam viav vias phom yog lub tshuab me me, uas muaj lub teeb me me rau kev khiav lag luam thiab tsis tas yuav siv tshuab siab. Nws yog qhov yooj yim rau kev khaws cia tom qab siv thiab tsis siv ntau qhov chaw. Ergonomics thiab lub teeb yuag handheld kev sojntsuam tuaj yeem txo tus neeg teb xov tooj kev tsis ua haujlwm. Lub teeb sib xyaw nrog kev sib xyaw ua ke ua rau cov khoom siv txav tau yooj yim thiab txav tau yooj yim hauv lub hoobkas.
High vuam qhov tseeb: high-precision thawb tswj thiab siab zoo vuam qhov tob tswj kom ntseeg tau tag nrho vuam zoo thiab zam vuam tsis muaj zog. Ua kom muaj qee qhov vuam zoo thiab tsis txhob hlawv lossis hlawv cov khoom.
Cov khoom siv muaj pes tsawg leeg
Ultrasonic handheld chaw vuam cov khoom suav nrog ntws tswj valve, transducer, ultrasonic tshuab hluav taws xob thiab taub hau vuam. Piv nrog rau cov khoom siv vuam siv tsis zoo, cov chaw siv lub tshuab ua haujlwm vuam yog sib dua thiab haum rau vuam kev ua haujlwm uas xav tau kev hloov chaw.
Ultrasonic cov tshuab hluav taws xob
Lub tshuab hluav taws xob hloov lub zog hluav taws xob los ntawm cov roj hluav taws xob ib-ntu txuas rau lub zog thiab cov hluav taws xob kom hloov cov hloov pauv mus rau kev siv tshuab kev co. Cov chav microprocessor tswj xyuas lub vuam kev hloov vuam thiab pub rov qab cov ntaub ntawv vuam tseem ceeb rau tus neeg siv los ntawm kev siv interface. Tus neeg siv interface tseem tso cai rau tus neeg teb xov tooj nkag mus rau qhov yuav tsum tau vuam txwv. Kev ua haujlwm tseem ceeb ntawm cov tshuab hluav taws xob ultrasonic yog los hloov 50-60 Hz hluav taws xob hluav taws xob (5000 watts) rau 20-40 kHz high-zaus hluav taws xob hluav taws xob. Qhov ntau zaus siv nyob rau hauv daim ntaub ntawv ultrasonic welding yog 20 kHz.
Lub tshuab hloov hluav taws xob
Lub tshuab hloov pauv tseem hu ua lub hloov pauv, uas hloov lub zog hluav taws xob los ntawm lub tshuab hluav taws xob mus rau kev siv tshuab kev co rau lub vuam txheej txheem. Nws muaj ntau ntau piezoelectric ceramic discs qhaub cij ntawm ob lub cav hlau (feem ntau yog titanium). Muaj txheej txheem nyias hlau ntawm txhua lub disc, uas tsim cov ntawv electrode. Thaum sine yoj hluav taws xob cov teeb liab tau pub rau lub transducer dhau ntawm qhov hluav taws xob, lub disc yuav nthuav dav thiab cog lus, uas ua rau lub zog axial ncov-rau-ncov siab ntawm 15 txog 20 μm. Lub tshuab hloov pauv yog qhov cuab yeej siv tau thiab yuav tsum tau ua nrog kev saib xyuas thaum lub sijhawm ua haujlwm welding. Thaum lub caij cov khoom raug puas lawm, lub tshuab hloov pauv yuav tsis ua haujlwm.
Horn
Lub zog txhawb ntawm lub tshuab raj muaj ob txoj haujlwm, feem ntau los ua kom nrov dua cov neeg kho tshuab kev tsim tawm ntawm qhov taub ntawm qhov hloov pauv thiab kis mus rau lub taub hau vuam. Qhov laj thawj thib ob yog muab ib qho chaw rau kev txhim kho lub pob ntawm lub vuam xovxwm. Thaum lub tshuab xa hluav taws xob siv ultrasonic lub zog, lub tshuab raj txuas ntxiv thiab sib cog lus. Zoo li lwm cov khoom hauv vuam vuam, lub tshuab raj yog lub cuab yeej tig mus, yog li nws yuav tsum resonate ntawm ib qho zaus nyob rau hauv thiaj li yuav hloov ultrasonic zog los ntawm qhov hloov mus rau lub taub hau vuam. Txhawm rau kom ua haujlwm tau zoo, lub tshuab raj yuav tsum yog ib nrab ntawm lub yoj ntawm ultrasonic nthwv dej hauv cov khoom uas ua los ntawm ultrasonic nthwv dej, lossis ntau yam ntawm qhov ntev. Feem ntau, nws yog ib nrab ntawm wavelength.
Vuam taub hau
Lub taub hau vuam yog cov khoom siv rau hauv vuam kab uas muab lub zog rau cov ntu kom txuas mus. Tus qauv tsim ntawm vuam lub taub hau yog qhov tseem ceeb rau kev ua tiav vuam. Lub taub hau vuam kuj yog qhov cuab yeej kho, thiab nyob rau hauv feem ntau cov ntawv thov, nws tseem tuaj yeem muab cov khoom siv kho tshuab. Nws feem ntau yog ua los ntawm aluminium lossis titanium. Aluminium fillets feem ntau siv rau hauv cov ntawv me me vim tias cov khoom siv no yuav ua rau hnav. Qee cov fillets muaj cov lus qhia tshwj xeeb uas nyuaj los txo cov hnav thaum vuam. Ib yam li lub tshuab raj kub, lub sijhawm ntev ntawm vuam kaum yuav tsum yog ib nrab ntawm nthwv dej ntawm ultrasonic nthwv dej hauv cov khoom uas nws tau ua, lossis ntau yam ntawm qhov ntev. Qhov no yuav xyuas kom meej tias qhov kawg fillet muaj qhov nrawm txaus rau lub vuam. Lub amplitude feem ntau yog ntawm 30 txog 120 μm.
