I-teknoloji ye-ultrasonic isetyenziswe ngokubanzi kwisinyithi, inkqubo ye-welding yeplastiki.Ngenxa yeemfuno zayo eziphezulu zokusebenza kwi-dynamics yesakhiwo, iindlela zoyilo zendabuko zokuxelisa kunye nokulungiswa kwesikhunta azikwazi ukulungelelanisa neemfuno eziguqukayo zeemveliso zeplastiki.Eli phepha liqala ngomgaqo wewelding yeplastiki ye-ultrasonic, iqhubela phambili nobuninzi bendalo kunye nohlalutyo lwemodyuli ngokusebenzisa indlela yesiqalelo esinesiphelo, iyilwe isixhobo esitsha, iyahlangabezana nodluliselo olusebenzayo kunye neemfuno zomsebenzi wamandla wokungcangcazela ngokufanayo.Kwinkqubo yoyilo ngokudityaniswa ne-ANSYS imodeli yeparametric, into yokwenziwa koyilo lovavanyo (DOE) kunye nemodyuli yoyilo olunokwenzeka (PDS), uyilo lweeparamitha kunye noyilo olomeleleyo, hlengahlengisa ubungakanani bejometri, ukwenza izixhobo kunye nobuninzi obuqhelekileyo be I-ultrasonic frequency match, i-modal amplitude ehambelanayo ngokulinganayo ebusweni, ukunciphisa ingxaki yesakhiwo sendawo yoxinzelelo loxinzelelo, Kwangaxeshanye, inokulungelelaniswa kakuhle nokutshintsha kwezinto kunye neeparamitha zokusingqongileyo.Yenziweizixhobo ze-ultrasonicingasetyenziswa emva kokucutshungulwa, nto leyo ethintela inkcitho yexesha kunye neendleko ezibangelwa kukuphinda kunxitywe izixhobo zokunxiba.
Njengoko ujongano loqhagamshelwano phakathi kwewelder yeplastiki ye-ultrasonickunye nezinto eziphathekayo, umsebenzi oyintloko wentloko yesixhobo se-ultrasonic kukudlulisa i-longitudinal vibration mechanical vibration ukusuka kwi-converter ye-amplitude kwizinto eziphathekayo ngokulinganayo nangempumelelo.Izinto ezisetyenziswayo zihlala zikumgangatho ophezulu we-aluminium alloy okanye i-titanium alloy.Ngenxa yokuba uyilo lwezinto zeplastiki zitshintsha, ukubonakala kwamawaka ahlukeneyo, intloko yesixhobo iya kutshintsha.Ubume bobuso obusebenzayo kufuneka buhambelane kakuhle nezinto eziphathekayo, ukwenzela ukuba ungonakalisi iplastiki xa ungcangcazela;Ngelo xesha, i-frequency esisigxina ye-vibration yokuqala ye-longitudinal vibration kufuneka ilungelelaniswe kunye ne-frequency ye-output yomatshini we-welding, ngaphandle koko amandla okugubha aya kusetyenziswa ngaphakathi.Xa intloko yesixhobo ingcangcazela, ukugxininiswa koxinzelelo lwendawo kuya kuveliswa.Indlela yokwandisa ezi zakhiwo zendawo nayo yingxaki ekufuneka iqwalaselwe kuyilo.Eli phepha lixoxa ngendlela yokusebenzisa i-ANSYS intloko yesixhobo soyilo ukunyusa iiparamitha zoyilo.
Uyilo lweuphondo lwe-welding kunye nesixhobozibaluleke kakhulu.Zininzi zasekhayaababoneleli bezixhobo ze-ultrasonicukuvelisa i-welders zabo, kodwa inxalenye enkulu yazo zilinganisa ezikhoyo, kwaye zisoloko zinxiba izixhobo, uvavanyo, ngale ndlela yohlengahlengiso oluphindaphindiweyo ukuze kuphunyezwe injongo yezixhobo kunye nolungelelwaniso lwamaza.Kweli phepha, indlela yento elinganiselweyo inokumisela ukuphindaphinda xa uyila indibano.Impazamo phakathi kweziphumo zovavanyo lwezixhobo ezenziweyo kunye ne-frequency yoyilo ingaphantsi kwe-1%.Kwangaxeshanye, eli phepha lazisa ingqikelelo ye-DFSS (uYilo lweSixt Sigma) ukwenza ngcono kunye noYilo lwezixhobo ngamandla.Ingcamango yoyilo lwe-6-Sigma kukuqokelela ngokupheleleyo ilizwi labathengi kwinkqubo yokuyila ukuphumeza uyilo olujoliswe kuyo;Ukongezelela, ukutenxa okunokwenzeka kwenkqubo yokuvelisa kufuneka kuqwalaselwe kwangaphambili ukuze kuqinisekiswe ukuba umgangatho wemveliso yokugqibela usasazwa kwinqanaba elifanelekileyo.
