1. Ukungaqondi kakuhle i-welding workpiece
Amandla e-Ultrasonic aqhuma ngokukhawuleza, umgca we-welding kufuneka uqulunqwe ngamaphuzu okanye imigca kwaye umgama wokuhambisa kufuneka uhambelane nendlela ye-ultrasonic welding. Abanye abantu bacinga ukuba okoko nje kuyimpahla yeplastiki, kungakhathaliseki ukuba indawo edibeneyo inokudityaniswa kakuhle, oku kukuqonda okungalunganga. Xa amandla akhawulezayo eveliswa, inkulu indawo edibeneyo, i-energy dispersion enzima kakhulu, i-welding effect imbi kakhulu, kwaye i-welding ayinakwenzeka. Amaza e-Ultrasonic ahanjiswa ngokude, ukulahleka kwamandla kuhambelana nomgama, kwaye umgama omde kufuneka ulawulwe ngaphakathi kwe-7.5 cm. Umgca we-welding kufuneka ulawulwe phakathi kwe-0.3-0.8mm njengeyona meko ingcono kakhulu, kwaye ubukhulu bodonga lwe-workpiece akufanele bube ngaphantsi kwe-2mm, ngaphandle koko ayikwazi ukuthungwa kakuhle, ngakumbi kwiimveliso ezifuna ukungabikho kwamanzi.
2. Ukungaqondi kakuhle izinto zokusebenza
Oomatshini be-welding be-Ultrasonic baneemfuno kwizinto ze-welding workpieces. Ayizizo zonke izixhobo ezinokudityaniswa. Abanye abantu bacinga ukuba nayiphi na impahla inokudityaniswa. Oku kukungaqondi kakuhle. Ezinye izinto ezahlukeneyo zinokudityaniswa kakuhle, kwaye ezinye zinokudityaniswa. Ezinye azihambelani. Indawo yokunyibilika kwezinto ezifanayo iyafana, kwaye inokudityaniswa ngomgaqo. Kodwa xa indawo yokunyibilika ye-welding workpiece inkulu kune-350 degrees, ayisafanelekanga kwi-welding ye-ultrasonic. Ngenxa yokuba i-ultrasound inyibilikisa iimolekyuli ze-workpiece ngokukhawuleza, isiseko somgwebo singaphakathi kwe-1-3. Ukuba i-welding ayilungile, kufuneka ukhethe ezinye iinkqubo ze-welding, ezifana ne-hot plate, i-spin melting, i-vibration kunye ne-friction. Ngokubanzi, imathiriyeli ye-ABS yeyona nto ilula ukuyidibanisa ngenxa yendawo yayo ephantsi yokunyibilika kunye nokuqina kwayo. Ngokuchasene noko, inayiloni yeyona nto inzima ukuwelda.
3, Iimpazamo ekukhethweni kwe-ultrasonic
Mangakanani amandla aphumayo okusetyenziswa, i-oscillation frequency, kunye ne-amplitude range kufuneka ithathelwe ingqalelo ngokwezinto ze-workpiece, indawo yocingo lwe-welding, nokuba kukho amacandelo e-elektroniki kwindawo yokusebenza, nokuba ayingeni moya. Intsomi kukuba okukhona amandla amakhulu, kokukhona angcono. Oku kwakhona kukungaqondi. Ukuba awukwazi kakhulu malunga ne-ultrasound. Kungcono ukubonisana nobunjineli kunye nabasebenzi bezobugcisa besityalo esiqhelekileyo sokuvelisa i-ultrasonic. Ukuba kunokwenzeka, kulungele ukunxibelelana nomenzi kwisiza, kwaye musa ukuphulaphula ngokungaboniyo ukulahlekisa abanye abasebenzi abangekho sikweni be-ultrasound. Okwangoku, iinkampani ezivelisa izixhobo ezinxulumene noko zintsonkothile kakhulu, uninzi lwazo ziindibano zocweyo zentsapho, ezikopisha isekethe ngokungqongqo, kwaye zibonakala ziqonda umgaqo wokusebenza. Isixhobo esikhutshelweyo sinesiphako esibulalayo. Enye kukuba umgangatho wezinto ezithengiweyo azinakuqinisekiswa, kwaye iteknoloji engundoqo yenkqubo yokuvelisa imveliso yesibini ayinakwenziwa. Isixhobo sihlala sisebenza ngokungazinzi ngexesha eliphakathi kunye nokusebenza kwamandla aphezulu, kwaye izinga lokufaneleka kwemveliso liphantsi. Ngamanye amaxesha izixhobo zonakele. Njengomguquli wamandla we-transducer, iiparameters zezixhobo zemagneti ezisetyenzisiweyo azikwazi ukulinganiswa, ukugcwala kwemagneti ubuninzi bemagnetic flux (Bs), induction induction magnetic (Bm), ukusebenza kakuhle kwemagnethi (Ue), ubuninzi bemagnetic flux (Br), ukunyanzeliswa (A / M) njl njl. Ngoko ke, ukuthenga i-ultrasound, kungcono ukuqonda imeko yenkampani kuqala. Kungale ndlela kuphela apho iingxaki ezingeyomfuneko zinokuncitshiswa kwixesha elizayo.
I-4, ukungaqondi kakuhle kwamandla okukhutshwa kwe-ultrasonic
Amandla emveliso ye-ultrasonic wave ifana nobukhulu kunye nobukhulu bephepha le-piezoelectric ceramic sheet, izinto eziphathekayo kunye nenkqubo yoyilo. I-transducer imile kwaye amandla aphezulu amile. Ukulinganisa amandla emveliso yinkqubo enzima. Akunjalo ukuba inkulu i-transducer, iityhubhu zamandla ezingaphezulu ezisetyenziswa kwisekethe, amandla amakhulu okuvelisa. Kufuneka ifune isixhobo sokulinganisa i-amplitude entsonkothileyo ukulinganisa ngokuchanekileyo i-amplitude yayo. Ngokudibanisa nokulahlekisa kwabasebenzi bokuthengisa, kunika abathengi ukuqonda okungalunganga ukuba inani lamandla ombane asetyenzisiweyo alibonakalisi ubungakanani bemveliso ye-ultrasonic power. Ukuba i-longitudinal energy eyenziwe iphantsi kwaye ukusetyenziswa kwangoku kukhulu, kunokuchaza kuphela ukusebenza kakuhle kwezixhobo, ngaphandle kwamandla. Yitsho.
5. Ukungaqondi kakuhle umgaqo we-welding
Inani elikhulu labantu abaye babandakanyeka kwi-ultrasonic welding iminyaka emininzi banokungaqondi kakuhle malunga nokuhanjiswa kwamandla e-ultrasonic. Kukholelwa ukuba ukudityaniswa kwamaza omsindo kumphezulu woqhagamshelwano ngokwenene kukungaqondi. Umgaqo welding oyinyaniso kukuba emva kokuba i-transducer iguqule amandla ombane kumandla ombane, idlula kwi-workpiece I-molecule yezinto eziphathekayo ziqhuba, kwaye i-wave yesandi iqhuba ukuxhathisa isandi kwizinto eziqinileyo zincinci kakhulu kunomoya. Xa i-wave yesandi idlula kwi-joint ye-workpiece, ukuxhathisa kwe-acoustic kwi-gap kukhulu, kwaye amandla okushisa avelisiweyo mkhulu kakhulu. Iqondo lokushisa kuqala lifikelela kwinqanaba lokunyibilika kwendawo yokusebenza, kwaye emva koko Ngoxinzelelo oluthile, i-seam ifakwe i-welded, kwaye ezinye iinxalenye ze-workpiece aziyi kufakwa ngenxa yokumelana ne-acoustic ephantsi kunye nobushushu obuphantsi. Umgaqo ufana nomthetho ka-Ohm.
I-6, Ukungaqondi kakuhle kwesakhiwo se-welding
Iindidi ezahlukeneyo ze-ultrasonic molds (Horn), imilo ye-workpiece inquma ukuma kwe-mold, kodwa ubukhulu kunye ne-radian yecandelo ngalinye kufuneka libalwe ngokungqongqo. Abanye abantu ngempazamo bacinga ukuba yintsimbi nje. Ingaba uyilo lunengqiqo okanye aluchaphazeli ngokuthe ngqo ukusebenza kakuhle, ixesha lokuphila, izinga lokufaneleka kwemveliso yesikhunta, kunye nokutshisa ngokuthe ngqo i-generator kwiimeko ezinzima. Izinto eziphathekayo zokubumba ngokuqhelekileyo i-aluminium ye-magnesium 7075, kwaye abanye abantu basebenzisa izinto ezingaphantsi kokunciphisa iindleko. Abavelisi be-mold abaqhelekileyo baneseti yeenkqubo zokuhlola ezingqongqo kwizinto ezingenayo, kwaye imilinganiselo esetyenzisiweyo icutshungulwa emva kokulinganisa isofthiwe yekhompyutha kunye nokuqinisekiswa. Umgangatho uqinisekisiwe. Ezi nkqubo azinakwenziwa ziiworkshops jikelele. Ngaphandle koyilo olufanelekileyo, iimolds eziveliswayo aziyi kuba neengxaki ezicacileyo zokusabela xa udibanisa ama-workpieces amancinci. Ukungalungi okuhlukeneyo kuya kwenzeka xa kusetyenziswa amandla aphezulu. Kwiimeko ezinzima, zonakalise ngokuthe ngqo amacandelo
