Cov qauv sib xyaw ua ke ntawm ultrasonic yas vuam tshuab
Cov khoom siv vuam khuam ultrasonic yog tsim los ntawm cov xovxwm, lub tshuab hluav taws xob, lub tshuab hloov pauv, tshuab raj, lub taub hau vuam thiab cov khoom ntu txhawb nqa cov cuab yeej.
1 Ultrasonic cov tshuab hluav taws xob
Kev ua haujlwm ntawm lub tshuab hluav taws xob ultrasonic yog los hloov lub zog hluav taws xob (50 Hz lossis 60 Hz) mus rau hauv ultrasonic zaus. Lub microprocessor tswj lub vuam kev vuam thiab pub rov qab cov ntaub ntawv vuam tseem ceeb rau tus neeg siv ntawm tus neeg siv khoom sib txuas. Tus neeg siv interface tseem tso cai rau tus neeg teb xov tooj nkag mus rau qhov yuav tsum tau vuam txwv.
Hlau Yas Welder
2 Vuam pawg / Acoustic zog system Lub vuam viav vias muab ultrasonic lub tshuab kev co, uas feem ntau yog ua los ntawm peb ntu: hloov pauv, tshuab raj thiab lub taub hau vuam, thiab tsau rau ntawm vuam xovxwm hauv nruab nrab ntawm lub tshuab raj. Cov khoom siv vuam vias yog lub resonator me ntsis zoo ib yam li lub ntsuas phuam tuning. Qhov hloov siab ntawm cov khoom siv vuam yuav tsum sib thooj nrog qhov nquag ntawm lub teeb liab hluav taws xob los ntawm lub tshuab hluav taws xob (nrog qhov sib txawv tsawg dua 30 Hz).
2.1 Cov Pauv Hloov
Kev hloov siab ntawm piezoelectric effect hloov lub ultrasonic zaus voltage los ntawm lub tshuab hluav taws xob rau ultrasonic kev siv tshuab kev co ntawm tib zaus. Nws muaj ob peb piezoelectric ceramic nplooj ntawv qhaub cij ntawm ob hlau (feem ntau yog titanium) cov blocks. Muaj txheej txheem nyias daim hlau ntawm cov nplooj ntawv los ua cov hluav taws xob. Thaum cov teeb liab hluav taws xob sinusoidal xa mus rau transducer ntawm electrode, daim ntawv piezoelectric nthuav dav thiab sib cog lus, ua cov axial ncov-rau-ncov suab ntawm 15-20 μm. Lub tshuab hloov pauv yog qhov ua kom raug thiab yuav tsum ua nrog kev saib xyuas.
2.2 Xab
Lub tshuab raj muaj ob lub luag haujlwm. Nws txoj haujlwm tseem ceeb yog ua kom nrov dua cov neeg kho tshuab kev co tsim tawm thaum kawg ntawm lub transducer thiab kis kev vibration mus rau lub taub hau vuam. Lwm txoj haujlwm yog los muab txoj haujlwm rau cov khoom kho kho ntawm lub vuam xovxwm. Thaum lub zog ultrasonic thov rau lub transducer, lub tshuab raj kuj nthuav thiab sib cog lus. Ib yam li lwm feem hauv cov khoom siv vuam vias, lub tshuab raj yog lub cuab yeej sib dhos, yog li nws yuav tsum tau tsa lub suab tshwj xeeb ntawm qhov tshwj xeeb kom thiaj li hloov mus rau 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 hnub ntev lossis ib qho kev sib txuam ntawm ntau ib nrab ntawm lub yoj ntawm ultrasonic yoj hauv nws cov khoom tsim tawm. Feem ntau ib nrab wavelength.
2.3 Vuam taub hau
Lub taub hau vuam yog ib feem ntawm cov khoom siv vuam uas muab lub zog rau cov ntu kom txuas mus. Zoo li lub tshuab raj, lub taub hau vuam kuj yog lub cuab yeej txuas, thiab cov neeg kho tshuab los kuj tseem muaj nyob hauv feem ntau thov. Qhov ntev ntawm vuam lub taub hau yuav tsum yog ib nrab-nthwv dej lossis ib nrab nthwv dej ntawm ultrasonic yoj hauv nws cov khoom tsim tawm
Tus lej ntawm lej ntau ntawm. Qhov no xyuas kom meej tias qhov kawg ntawm lub taub hau vuam muaj ntau txaus kom ua tiav welding. Lub amplitude feem ntau yog 30 ~ 120 μm. Tus qauv tsim ntawm seem yuav tsum tau welded thiab kev sib koom tes txiav txim siab qhov loj thiab style ntawm lub taub hau vuam. Cov duab ntawm vuam lub taub hau yog qhov tseem ceeb heev, vim tias qhov kev ntxhov siab los ntawm axial nthuav thiab qhov cuam tshuam ntawm lub taub hau vuam tuaj yeem ua rau tawg ntawm qhov muaj zog. Hauv qee qhov kev siv, vuam lub taub hau yog machined nrog ntau qhov axial slots. Qhov no yog los xyuas kom meej tias qhov siab tshaj plaws nyob hauv qhov ntev. Qhov kawg ntawm vuam lub taub hau xa cov ultrasonic zog rau qhov chaw yuav tsum tau welded. Qhov xaus yuav tsum tau tsim tshwj xeeb kom phim rau cov ntu kom ntseeg tau tias ntau lub zog hloov ntawm lub taub hau vuam thiab cov ntu. Feem ntau qhov kawg ntawm vuam lub taub hau los ua ib qho profile txuam qhov txuas ntawm lub qhov.
Txhawm rau tiv thaiv indentation thiab txo hnav, aluminium yuav tsum plated nrog nickel lossis chromium. Thaum muaj kev cuam tshuam lossis hnav tsis kam yog qhov yuav tsum tau ua, thiab thaum vuam ntim cov yas los yog kos cov ntawv hlau, hlau vuam taub hau yuav tsum muaj. Lub taub hau hlau tsis muaj lub zog tsis muaj zog thiab tsuas yog siv qee lub sijhawm nkaus xwb. Cov khoom seem, cov qauv tshwj xeeb lossis cov loj-loj uas feem ntau yuav tsum muaj cov vuam sib txuas ua ke (cov menyuam menyuam poj niam vuam taub hau). Lub sijhawm no, lub hauv paus vuam taub hau yog ua los ntawm aluminium, titanium lossis steel secondary vuam taub hau txuas nrog lub hauv paus vuam taub hau thiab qhia lub zog.
3 Xov Xwm
Cov xovxwm yog siv los kho cov khoom siv vuam thiab siv lub zog uas yuav tsum muaj rau vuam. Nws muaj lub hauv paus rau kev kho kho kom ruaj khov thiab cua tshuab kom zoo rau kev thov lub zog. Cov xovxwm yog nruab nrog lub ntsuas cua siab thiab lub ntsuas kom tswj tau qhov ntsuas lub zog vuam. Nws yuav tsum raug sau tseg tias qhov tshwj xeeb ntsuas qhov siab tau teev rau ntawm cov khoom siv ultrasonic welding tsis tas yuav zoo tib yam li vuam quab yuam los ntawm lwm qhov txuas nrog qhov ntsuas ntawm lub zog siab. Lub zog vuam yuav tsum tau ntsuas nrog lub ntsuas cua kom thiaj li sib piv ncaj qha ntawm lub zog vuam ntawm cov sib txuas sib txawv. Tseem muaj kev tswj ntws qhov ntsuas ntawm qhov xovxwm kom kho qhov nrawm ntawm vuam lub taub hau nce mus rau qhov feem yuav tsum tau txais. Qee cov khoom siv vuam siv electromagnetic force pressurization system los hloov cov tsoos lub tog raj kheej, uas tuaj yeem tswj tau qhov kev mus kom ze qhov nrawm, uas tau txais txiaj ntsig thaum vuam me lossis qhov tseeb.
4 Cov cuab yeej txhawb nqa
Lub hauv paus nias txhim kho qhov cuab tam uas txhawb nqa rau cov ntu thaum vuam. Cov cuab yeej txhawb nqa tau tshwj xeeb tau tsim los tiv thaiv qhov qis qis ntawm txav thaum ultrasonic siv. Nws feem ntau ua tiav rau hauv cov duab uas ua tib zoo sib txuas nrog cov nplaim ntu ntawm ib feem. Kev sib haum xeeb yog los ntawm yooj yim mus rau qhov xwm yeem, nyob ntawm qhov qauv tsim. Qhov qis dua yuav tsum tau muab tso kom siab thiab txhawb nqa. Lub qhov yuav tsum kho lossis lub hauv paus yuav tsum muab kho kom paub meej tias qhov ntu yog sib dhos rau lub taub hau vuam. Cov khoom siv tau tuaj yeem ua tiav los ntawm ntau cov ntaub ntawv. Stainless hlau yog qhov kev xaiv zoo tshaj plaws vim tias nws yooj yim rau tshuab thiab txhuam. Cov khoom siv tshwj xeeb tuaj yeem tam sim no ua tiav ncaj qha ntawm CAD cov ntaub ntawv. Cov kab loj, nyuaj, khib-puab lossis cov pob me me feem ntau clamped los ntawm casting mos polyurethane.
