Isimiso se-Ultrasonic Welding / Theory
Ukushisela kwe-Ultrasonic, okwaziwa nangokuthi ukubopha kwe-ultrasonic, kuyinqubo lapho amagagasi omsindo we-high-frequency (ultrasonic) asetshenziswa ezintweni ezimbili noma ngaphezulu zomsebenzi ezigcinwe ndawonye ngaphansi kwengcindezi yokuzihlanganisa zibe ucezu olulodwa. Ngokuvamile kusetshenziselwa ukuhlanganisa izingxenye zepulasitiki — ikakhulukazi lezo ezenziwe ngezinhlobo ezehlukene zepulasitiki — i-welding ye-ultrasonic ibopha unomphela okokusebenza ngakunye ngaphandle kwesidingo sezinto zokunamathisela noma izinto zokufaka imishini.
Ukushisela kwe-Ultrasonic kuyindlela yezimboni lapho kunyakaziswa khona imvamisa ephezulu ye-acoustic yasendaweni isetshenziswa kuzinto zokubamba ezigcinwe ndawonye ngaphansi kwengcindezi yokwakha i-weld-state weld. Ijwayele ukusetshenziselwa amapulasitiki nezinsimbi, futhi ikakhulukazi ukujoyina izinto ezingafani. Ku-welding ye-ultrasonic, awekho amabhawodi wokuxhuma, izipikili, izinto zokunamathisela, noma izinto zokunamathisela ezidingekayo zokubopha izinto ndawonye. Uma kusetshenziswa izinsimbi, isici esivelele sale ndlela ukuthi izinga lokushisa lihlala ngaphansi kwezinga lokuncibilika kwezinto ezibandakanyekile ngaleyo ndlela zivimbele noma yiziphi izakhiwo ezingafuneki ezingavela ekuvezeni izinga eliphezulu lokushisa kwezinto.
Isebenza kanjani i-welding ye-ultrasonic?
Yonke imisebenzi ye-ultrasonic welding izohluka ngokuya ngezinto zepulasitiki ezihlanganiswayo, ukwakheka kwezinto zokusebenza, nezinye izinto. Noma kunjalo, inqubo yonke ngokuvamile iyafana. Izingxenye ezifakwa ngezinsimbi zihlanganiswe ndawonye futhi zifakwe phakathi kwesihlahla "sensimbi", esizigcinayo, kanye ne-sonotrode yensimbi, noma uphondo.
Uphondo luxhunywe kwi-transducer, edala ukudlidlizela okukhulu ngokweqile; uphondo ludlulisela lesi sinyakazisi esidlidlizelayo emisebenzini ecindezelwa kuyo. Ukudlidlizela kubangela ukuthi ipulasitiki incibilike kancane, futhi ingcindezi esetshenziswa yisidleke iyazihlanganisa ndawonye, yakhe inhlanganisela. Imvamisa, indawo esibonakalayo lapho izingxenye zombili zihlangana ndawonye yenzelwe ngokukhethekile ukwenza izinqubo zokuncibilika nokubopha. Ngemuva kokuthi izingxenye zihlanganiswe kahle, ukudlidlizela kuyama bese uplastiki uphola ngokushesha okukhulu, kwakheke isibopho esiqinile ngendlela exakile.
