1. kev tshawb xyuas qhov yooj yim ntawm kev tsim
Txhawm rau kom ua tiav qhov kev ntsuas vuam zoo, cov yam tseem ceeb uas yuav tsum tau kuaj xyuas yog li nram qab no:
Joint Muaj zog sib koom ua ke
§ Seb puas yuav vuam vuam tas
Seb puas tso cai xaum ntaub
§ Tshawb xyuas qhov tseeb ntawm cov yas ntawm cov yas ua. Cov ntaub ntawv twg tuaj yeem ua tau raws li cov qauv tsim ntawm cov khoom thiab ua tau raws li cov kev mob yooj yim haum rau kev ua ultrasonic.
Requirements Cov khoom lag luam yuav tsum tau muaj
Cov chaw sib koom ua ke thiab daim ntawv
Cov qauv tsim kho tom ntej, yuav tsum tuaj yeem txhim kho lub plhaub thaum lub sijhawm ua haujlwm vuam
Seb lub taub hau vuam siv los xa ultrasonic lub zog ua ntej weld sib koom tes tsim qauv ua kom pom tseeb
2. welding qhov chaw tsim tsom
Tsim los ua kom muaj peev xwm kis tau lub zog ultrasonic
Yog hais tias lub vuam saum npoo muaj qee qhov kev ncua deb los ntawm lub nplaim hu rau ntawm ultrasonic welding taub hau, tus tswv cuab lub plhaub yuav tsum sib zog txaus los xa cov zog ultrasonic. Cov yas muag tsis tuaj yeem xa hluav taws xob tau zoo. Lub tuab ntawm lub plhaub phab ntsa yuav tsum muaj peev xwm txaus kom tsis txhob rhuav tshem ntawm thaj chaw welded. Nyias phab ntsa yooj yim rau weld. Cov neeg kho tshuab zog hauv cov txheej txheem so.
(1) Cov fab thiab cov hauv txuas ntawm lub weld
Txhua cov ces kaum thiab npoo yuav tsum muaj sib npaug, thiab cov npoo ntse tuaj yeem tsim kom muaj ultrasonic zog thiab ua rau tawg lossis tsis tsim nyog vuam.
(2) Cov teeb meem tsim khoom tsim khoom
Tej qhov chaw txuas ntxiv dhau ntawm lub cev, xws li tav, txhav, pob zeb, muaj kev tawg yooj yim vim kev co lossis cua sov dhau lub sijhawm ultrasonic vuam. Ib qho ntxiv, lwm yam khoom tsim ua ke xws li lub qhov dej tawm los yog cov xov hlau kuj tseem ua kom cov vuam nyhuv. Hauv kev txiav txim siab, lub npoo npoo thiab cov fab xwm yeem, qhov loj me me, thiab lub sijhawm vuam luv tuaj yeem ua tiav cov txiaj ntsig vuam zoo tshaj plaws. Yog tias tsim nyog, silica gel tuaj yeem siv los tiv thaiv kev co ntawm cov khoom siv hluav taws xob, qhov dej, thiab lwm yam.
(3) lub sijhawm vuam ntawm lub weld
Qhov tsim nyog, ob lub plhaub yuav tsum sib dhos ua ke thiab tsis txhob xaj thaum tab tom vuam. Qhov zoo tshaj plaws anastomosis yog tias ob qho tuaj yeem sib zog los ntawm lub zog sab nraud tab sis tsis ntom heev. Qhov sib txawv zoo tshaj plaws yog 0.05 txog 0.1 hli. Nyob ntawm qhov loj me ntawm weld, qhov siab sib txawv ntawm ob lub qhov txuas yog tsawg kawg 1.0 hli.
Pom zoo kom sib txawv a = 0.025 ~ 0.05 hli; b = min. 1.0 hli
(4) hloov hluav taws xob yuav tsum ua kom zoo ib yam
Tus qauv tsim ntawm kev sib koom ua ke cuam tshuam cov tsis sib xws ntawm lub zog hloov. Feem ntau, khoov, bevels lossis qhib hauv txoj kev xa hluav taws xob txo qis kev siv zog ntawm ultrasonic tsis xa mus rau qhov chaw weld.
Qhov cheeb tsam X hauv daim duab yog qhov ntxim nws tsis txaus lossis muaj soldering.
(5) txoj haujlwm ntawm qhov kev sib koom ua ke
Cov xwm txheej zoo tshaj plaws yog qhov sib koom ua ke zoo txhua yam nyob ntawm tib qhov siab thiab tuab mus rau saum npoo ntawm lub taub hau weld. Yog tias qhov no tsis yog teeb meem, vim tias qhov kev ncua deb ntawm qhov kev sib koom ua ke mus rau saum npoo ntawm lub taub hau weld yog qhov sib txawv, nws yog qhov yooj yim kom tsis muaj qhov tsis muaj vuam vuam.
Hauv daim duab, qhov kev ncua deb ntawm L1 thiab L2 tsis sib npaug, thiab ib qhov saum npoo tsis sib thooj rau saum npoo ntawm lub taub hau vuam, thiab lub zog poob kis mus rau qhov chaw tiv tauj ntawm ob lub plhaub yog qhia.
(6) lub weldment thiab weld lub taub hau sib cuag saum npoo
Cov xwm txheej zoo tshaj plaws yog qhov sib tiv tauj ntawm lub khauj khaum thiab lub raj yog qhov loj thiab tiaj tus, thiab saum npoo ntawm lub tshuab raj yuav tuaj yeem ua ib feem. Yog hais tias qhov saum npoo ntawm lub tshuab raj me dua li ntawm qhov sib koom ua ke, txawm hais tias lub vuam tseem tuaj yeem ua tiav, ib feem ntawm lub zog yuav tsis kis mus rau qhov sib koom ua ke, thiab nws yog qhov tsim nyog los ua kom lub siab kom ua tiav qhov zoo vuam, tab sis nce lub ntsej muag lub siab yuav ua rau ua kab mob nyob rau saum npoo ntawm weldment. Polished lossis tsis ncaj saum npoo yog tshwj xeeb tshaj yog rau weld lub taub hau indentations, thiab ntxiv ntawm PE txhaj tshuaj pwm txo kev poob qis.
Tus tswvcuab lub plhaub uas tau sib txuas nrog lub tshuab raj yuav tsum loj kom zoo li lub horn tiv tauj saum npoo, piv txwv li, ib qho yuav tsum dav kom ntau li ntau tau.
