I. Yintoni i-ultrasound?

Amaza e-ultrasonic yindlela esebenzisa amandla aveliswa kukungcangcazela okuphezulu ukuze isebenze kumphezulu wesixhobo somsebenzi, ngaloo ndlela kufezekiswa ukuhlanganiswa kweendawo zesinyithi kunye.

II. Umgaqo-nkqubo Wokusebenza Wamaza E-Ultrasonic

1. Amandla ombane aguqulwa abe kukungcangcazela koomatshini okuphindaphindeka kakhulu, okuthi emva koko kudluliselwe kwi-welding nozzle ngentloko yokungcangcazela elungiswe ngesandi. Izixhobo zokusebenza eziphezulu nezisezantsi ziyakhuhlana phantsi kwemijikelo yoxinzelelo lwamaxesha angama-20,000 okanye angama-40,000 ngomzuzwana. Isiphumo esidibeneyo sokungcangcazela okuphindaphindeka kakhulu kunye noxinzelelo sisasaza umaleko omncinci wezinto kunye nee-oxides kumphezulu wezinto zokusebenza, senza i-diffusion weld ecocekileyo nelawulekayo. Ngokudityaniswa kwee-athomu phakathi kwezinto zokusebenza, umaleko wokudityaniswa kwe-metallurgical othembekileyo ekugqibeleni uyenziwa.
2. Umsinga ophantsi uguqulwa ube ngumsinga ophantsi ngejenereyitha ube ngumsinga ophantsi. Umsinga ophantsi uguqulwa ube ngumsinga ophantsi nge-transducer ube ngumsinga wombane. I-amplitude modulator kunye nentloko yokudibanisa zinoxanduva lokulungisa umsinga wokungcangcazela. Phantsi koxinzelelo oluthile oluzinzileyo, izakhiwo ze-molecular kumphezulu wesinyithi ziyangqubana kwaye zingqubane, zifezekisa ukungenelela phakathi kwe-molecular, ngaloo ndlela zigqibezela ukujija.

Ulwazi olusisiseko kunye nokusombulula iingxaki ze-ultrasound

III. Iimpazamo eziqhelekileyo kwi-Ultrasonic Welding

(a) Ukutywina okungaphelelanga

1. Amandla okukhupha ukuwelda anganelanga: uxinzelelo olunganelanga, ubukhulu obunganelanga, okanye isiseko asiqinanga ngokukhuselekileyo.
2. Amandla okuwelda anganelanga: Ifomula yokubala amandla okuphuma yi-E=P×T=F×V×T=μN×A×f×T (apho u-E ngamandla, u-P ngamandla, u-V sisantya, u-μ yi-coefficient of friction, u-N luxinzelelo, u-A yi-amplitude, u-f yi-frequency, kwaye u-T lixesha). Amandla anganelanga aya kukhokelela ekuweldingni okungalunganga.
3. Iileya zeoyile okanye ze-oxide kumphezulu wezinto zinokuchaphazela isiphumo sokubopha kwe-welding.
4. Ukuba amazinyo abukhali kakhulu, anokungena lula kwi-weldment ngexesha lokuwelda.
5. Umphezulu we-weldment une-coating yezinto ezingafanelekanga kwi-ultrasonic welding.
6. Izinto ezidityanisiweyo azifanelekanga ukudityaniselwa nge-ultrasonic.

(ii) Isiseko sentloko yokuwelda

Unobangela : Xa intloko yokwelda okanye isiseko sokwelda sidibana nezinto, kuveliswa amaqondo obushushu aphezulu kakhulu, okubangela ukungena kweemolekyuli phakathi kwezinto kunye nentloko yokwelda okanye isiseko, nto leyo ebangela ukunamathela.

Isisombululo :

1. Hlola amazinyo entloko kunye nesiseko se-welding. Ukuba ukuguguleka kukhulu, kuya kubangela ukuba ubushushu bunyuke, kwaye kufuneka kulungiswe kwangethuba.
2. Ngelixa kuqinisekiswa iziphumo zokuwelda, amandla anokwandiswa ngokufanelekileyo kwaye ixesha lokuwelda lifinyezwe ukuze kuncitshiswe ukutshintshiselana kwamandla okugqithisileyo phakathi kwentloko yokuwelda kunye nezinto.

(iii) Ukuwelda imifantu

1. Ukuqhekeka kujikelezo lwe-weld joint: Xa kudityaniswa iileya ezininzi zezinto, umphetho we-weld joint wenza ithambeka. Xa intloko ye-welding ingcangcazela, iya kusebenzisa amandla okutsala emngxeni, nto leyo enokubangela ukuqhekeka ngokulula.
2. Isisombululo : Yenza unyango olukhethekileyo kumphetho wejoyinti ye-weld ukuqinisekisa ukusasazwa koxinzelelo ngokulinganayo kunye nokunciphisa amandla okuxinana aveliswa kukungcangcazela.
3. Imingxunya kufutshane nejoyinti yesolder: Ukungcangcazela kwentloko yesoldering kubangela ukuba izinto zihambe ziye phambili nangasemva. Umzekelo, xa ifoyile ye-aluminium iqhagamshelwe kwibhetri, ukutsala kunokubangela ukwaphuka ngokulula.
4. Izisombululo : ① Tshintsha indlela ipateni yamazinyo (umz., sebenzisa iipateni ezithe tyaba) ukuze ulungise indlela amandla asebenza ngayo kwizinto; ② Yandisa ithebhu ngokufanelekileyo ukuze wenze isithuba se-buffer phakathi kwebhetri kunye nejoyinti ye-solder.

(iv) Ukuguquguquka okukhulu kwamandla okukhupha

Isizathu Zininzi izinto ezichaphazela amandla okukhupha, kwaye kufuneka zihlolwe nganye nganye.

Isisombululo :

1. Hlola ukufakwa kweyunithi yesithathu, jonga ukuba akukho monakalo na, uze uyidibanise kwakhona ukuba kuyimfuneko.
2. Qinisekisa ukuba izikrufu zesiseko ziqiniswe kakuhle.
3. Jonga izikhewu kwindawo apho i-base clamp ikhona.
4. Hlola izixhobo zokuwelda ukuqinisekisa ukuba iindawo zokuwelda ziyafana ngalo lonke ixesha.
5. Jonga umphezulu wento ukuba akukho mdaka okanye amabala eoyile.
6. Qinisekisa ukuba iinkcukacha zezinto ezingenayo ziyahambelana (xa i-welding head stroke ilungisiwe, umahluko kubukhulu kunye nobunzima bezinto ziya kubangela ukuguquguquka kwamandla okukhupha).
7. Jonga uzinzo lomoya ofumaneka kumzi-mveliso uze ujonge ukuba kukho utshintsho kwigeyiji yoxinzelelo lomoya ongenayo na.
8. Jonga ukuba imveliso ye-ultrasonic yebhokisi yombane izinzile na.

(v) Umthwalo ogqithisileyo

Iimbangela ziquka iimeko ezimbini: ukugqithisa amandla kunye nokugqithisa rhoqo.

Isisombululo :

1. Nciphisa iiparameter zokuwelda ngokufanelekileyo.
2. Nciphisa ubunzulu bokwehla kwentloko yokweluka ukuqinisekisa ukuba kukho umsantsa othile ohlala ukhona phakathi kwentloko yokweluka kunye nesiseko.
