Ultrasonic Welding Principle / Theory
Welding na Ultrasonic, wanda aka fi sani da haɗin ultrasonic, tsari ne wanda ake amfani da raƙuman sauti mai ƙarfi (ultrasonic) zuwa ɗakunan aiki guda biyu ko sama waɗanda ake riƙe su tare cikin matsi don haɗa su cikin yanki ɗaya. Ana amfani da shi sosai don haɗuwa da sassan filastik-musamman waɗanda aka yi da nau'ikan filastik daban-daban-walda na ultrasonic yana ɗaure ɗayan ɗayan aikin ba tare da buƙatar adhesives ko kayan aikin injiniya ba.
Ultrasonic waldi ne mai masana'antu da fasaha inda high-mita ultrasonic Ft Irfan vibrations ana gida amfani da workpieces ana gudanar tare a karkashin matsin don ƙirƙirar wani m-jihar Weld. An saba amfani dashi don robobi da karafa, kuma musamman don shiga abubuwa marasa kamanni. A cikin walda na ultrasonic, babu maɓallan haɗi, kusoshi, kayan siyarwa, ko adhesives da ake buƙata don haɗa kayan tare. Lokacin amfani da karafa, halayyar sananniyar wannan hanyar ita ce, yawan zafin jiki yana kasancewa a ƙasa da ƙarshen narkewar kayan aikin don haka hana duk wani kayan da ba'a buƙata wanda zai iya tashi daga tasirin zafin jiki mai yawa na kayan.
Ta yaya waldi ultrasonic aiki?
Duk aikin walda na ultrasonic zai banbanta dangane da kayan roba da ake hadawa, fasalin kayan aiki, da sauran abubuwan. Koyaya, tsarin gabaɗaya gaba ɗaya ɗaya ne. Sassan da ake yin walda da su an hada su da sandwiched tsakanin “gida” na karfe, wanda yake riƙe su a wurin, da sonotrode na ƙarfe, ko ƙaho.
Connectedaho yana haɗuwa da transducer, wanda ke haifar da tsananin saurin girgizawa; Kakakin yana canzawa wannan motsi na motsi zuwa ga kayan aikin da aka matse shi. Vibararrawar ta sa filastik ɗin ya narke kaɗan, kuma matsin da gurbi ya yi amfani da shi ya haɗa su wuri ɗaya, ya samar da haɗin gwiwa. Yawanci, yankin musayar ra'ayi inda ɓangarorin biyu suka haɗu an tsara shi musamman don sauƙaƙe ayyukan narkewa da haɗin kai. Bayan an haɗa sassan yadda yakamata, sai girgizar ta tsaya kuma filastik ya huce sosai, yana haifar da daɗaɗa ƙarfi.
