Cov kev tsis xws luag thiab txoj kev kho ntawm ultrasonic vuam
1. Lub zog tsis tuaj yeem ncav cuag cov qauv uas xav tau
Ua ntej txhua yam, peb yuav tsum nkag siab tias lub zog ntawm kev ua haujlwm ultrasonic welding tsis tuaj yeem ncav cuag lub zog ntawm ib-thooj moulding, nws tuaj yeem tsuas hais tias nws ze rau lub zog ntawm ib-ntu molding, thiab tus qauv rau vuam lub zog. yuav tsum vam khom ntau txoj kev koom tes. Cov kev koom tes no yog dab tsi? Dab tsi
Cov khoom siv yas: Qhov tshwm sim ntawm kev sib xyaw ntawm ABS thiab ABS yog qhov muaj zog tshaj qhov fusion ntawm ABS thiab PC, vim tias cov ntsiab lus melting ntawm ob cov ntaub ntawv sib txawv, thiab lub zog ntawm cov fusion tsis tuaj yeem sib npaug. Txawm hais tias peb tau sib tham txog seb ABS thiab PC tuaj yeem sib txuas ua ke, lo lus teb tau yog, tab sis yog lub zog tom qab vuam yam peb xav tau? tsis tsim nyog!
Ntawm qhov tod tes, yog tias ABS melts nrog PP thiab PE ua li cas? Yog tias cov xaim hluav taws xob tam sim ntawd tawm li ntawm 150 qib kub, txawm hais tias cov khoom siv ABS tau yaj, PVC, PP thiab PE nyuam qhuav ua mos. Peb txuas ntxiv mus ua cua sov rau siab dua 270 degrees. Lub sijhawm no, PVC, PP thiab PE tau mus txog lub tshuab hluav taws xob ultrasonic vuam, tab sis cov khoom siv ABS tau decomposed mus rau lwm tus qauv molecular.
Peb txoj kev txiav txim siab tuaj yeem rub tawm los ntawm kev sib tham saum toj no:
1. Plastics nrog tib lub ntsiab lus melting muaj dua lub zog vuam.
2. Qhov ntau dua qhov chaw melting qhov sib txawv ntawm cov khoom yas, qhov me dua qhov vuam lub zog.
3. Qhov ntsuas ntom ntau dua ntawm cov khoom yas (nyuaj), lub vuam lub zog siab dua thiab qhov qis dua ntom ntom (siab tawv).
2.Txheej muaj cov nplai lossis tawg nyob saum npoo ntawm cov khoom
Hauv kev ua haujlwm ultrasonic welding, nti muaj feem ntau nyob rau saum npoo ntawm cov khoom, thiab pob txha tawg lossis kab tawg tau tsim ntawm qhov sib koom ua ke.
Vim tias muaj ob qho xwm txheej hauv kev ua haujlwm hauv ultrasound:
1. Lub zog kub kub ncaj qha mus cuag cov nplaim yas cov khoom.
2. Kev co kis. Yog li no, thaum ultrasonic kev co ua rau cov khoom yas, qhov chaw ntawm cov khoom yog yooj yim hlawv, thiab cov kem yas lossis lub qhov nrog tuab ntawm tsawg dua 1m / m kuj yog yooj yim tawg. Qhov no yog qhov yuav tsum tau ua dhau los rau kev ua haujlwm ultrasound. zam.
Ntawm qhov tod tes, vim tsis muaj lub zog tawm ntawm lub zog ultrasonic (nthuav tawm theem thiab HORN sab sauv tuag), nws siv sijhawm ntev los hloov lub siab ua kom muaj kev sib txhuam lub zog ua rau lub zog cua rau vuam siv los them rau kev sib txuam ntawm lub zog hluav taws xob. Tsis muaj tsim tawm hluav taws xob. Qhov txheej txheem vuam tsis tuaj yeem txais kev vibration thiab txhuam kev kub tam sim, tab sis yuav tsum muaj lub sijhawm vuam kom tsim nyog ua kom kub. Txawm hais tias lub ntsiab lus melting ntawm cov khoom yas mus txog lub vuam nyhuv, qhov kub nyob ntawm qhov chaw ntawm cov khoom siv ntev dhau, thiab kev sib xyaw nrog kub thiab siab tuaj yeem ua rau cov khoom hlawv, tawg lossis tawg. Yog li no, tso tawm hluav taws xob (tus naj npawb ntawm ntu), lub sijhawm vuam, lub zog hnyav thiab lwm yam kev sib koom tes yuav tsum muab xam rau lub sijhawm no kom kov yeej qhov tsis muaj haujlwm.
kev daws:
1. Txo kev ntxhov siab;
2. Txo lub sijhawm qeeb (lub vibration thaum ntxov);
3. Txo qhov vuam lub sijhawm;
4. Cov ntaub ntawv npog hauv cov ntawv tshaj tawm (xws li hnab PE);
5. Kev kho cov npoo ntawm cov pwm (ua tawv tawv lossis chrome-plated);
6. Txo cov naj npawb ntawm cov tshuab lossis kom tsis txhob muaj lub ntsej muag loj ntawm cov pwm sab saud;
7. Rau cov khoom lag luam uas yooj yim tawg lossis tawg, cov khoom siv yuav tsum tau muab cov roj hmab muag muag lossis lwm cov khoom los yog npog nrog cork (cov khoom no tsis cuam tshuam rau lub zog vuam);
8. Ntxiv R kaum sab xis rau cov khoom lag luam uas yooj yim tawg.
3. Kev faib tawm ntawm cov khoom
Muaj peb qho laj thawj rau kev hloov pauv no:
1. Lub cev thiab cov khoom yuav tsum tau welded lossis lub hau npog tsis tuaj yeem sib txuam vim muaj lub kaum ntse ntse lossis arc;
2. Lub thickness ntawm cov khoom yog nyias (li 2m / m) thiab qhov ntev tshaj 60m / m;
3. Cov khoom lag luam yog deformed thiab distorted vim muaj tej yam xws li kev txhaj tshuaj molding siab.
Yog li no, thaum peb cov khoom lag luam deformed los ntawm kev ua haujlwm ultrasonic, nws zoo li yog qhov ua rau ntawm ultrasonic welding rau saum npoo. Txawm li cas los xij, qhov no tsuas yog tshwm sim. Txhua yam ua ntej ua cov khoom lag luam yas welded, dab tsi ntawm cov txiaj ntsig yuav tsim tom qab welding. Yog tias tsis muaj kev sib tham txog cov laj thawj tseem ceeb, nws yuav siv sijhawm ntau los daws qhov teeb meem ntawm cov tshuaj tsis raug. Ntxiv mus, hauv ultrasonic qhov kev ua haujlwm ua haujlwm vuam kev ua haujlwm tsis yog (tsis yog ncaj qha melting), lub siab hauv qab 6kg tsis tuaj yeem hloov cov bristness thiab inertia ntawm cov yas.
Yog li tsis txhob siv' t sim siv lub zog muaj zog los hloov lub deformation ua ntej welding (qhov siab tshaj plaws ntawm lub tshuab vuam yog 6kg), suav nrog kev yuam kom nruj nrog cov pwm. Tej zaum peb tseem yuav poob rau hauv qhov chaw dig muag, uas yog sib tham txog qhov ua rau deformation los ntawm qhov chaw, uas yog, nws tsis yog pom lub qhov muag liab qab ua ntej vuam, tab sis tom qab lub vuam ultrasonic ua tiav, qhov deformation yog pom tseeb. Qhov laj thawj yog tias ua ntej cov khoom tau welded, nws nyuaj rau nrhiav qhov yuam kev ntawm cov khoom nws tus kheej hauv ntau cov ces kaum, hluav taws xob thiab cov khoom seem vim muaj cov fuse. Tab sis tom qab lub vuam ultrasonic ua tiav, nws zoo li deformed uas tuaj yeem pom nrog qhov muag liab qab.
Tshuaj:
1. Txo qhov siab (lub siab yog zoo tshaj hauv qab 2kg);
2. Txo ultrasonic lub sijhawm vuam (txo lub zog txheem);
3. Nce lub sijhawm tawv (tsawg kawg 0.8 vib nas this lossis ntau dua);
4. Txheeb xyuas seb tus txheej txheem ultrasonic siab dua thiab qis dua tuaj yeem hloov kho hauv zos (thaum tsis tsim nyog).
5. Txheeb xyuas cov khoom tseem ceeb ntawm cov khoom deformation thiab ua kom muaj kev txhim kho.
