Impembelelo yokuSebenza okuPhezulu rhoqo (i-HFMI), ekwabizwa ngokuba yi-Ultrasonic Impact Treatment (i-UIT), unyango oluphezulu lwefreyimu eyilelwe ukuphucula ukudinwa kokuchaphazeleka kwezakhiwo ezi-welding.Kuninzi lwezicelo zorhwebo le nkqubo ikwabizwa ngokuba yi-ultrasonic peening (UP ).
Lunyango olubandayo olubandakanya ukubetha i-weld toe ngenaliti ukwenza ukwandiswa kwerediyo yayo kunye nokwazisa intsalela yoxinzelelo.
Ngokubanzi, inkqubo esisiseko ye-UP ebonisiweyo inokusetyenziselwa unyango lwe-weld toe okanye i-welds kunye neendawo ezinkulu zomhlaba xa kukho imfuneko.
Ababethi abaShukumayo abaSimahla
Izixhobo ze-UP zisekwe kwinto eyaziwayo ukusuka kwi-40 yenkulungwane yokugqibela izisombululo zobuchwephesha zokusebenzisa iintloko ezisebenzayo ezinesitrayikhi eshukumayo sokukroba isando. Ngelo xesha nasemva koko, inani lezixhobo ezahlukeneyo ezisekwe ekusebenziseni izitrayikhi ezishukumayo ezikhululekileyo zaphuhliswa kunyango lwempahla kunye nezinto ezi-welding ngokusebenzisa izixhobo zomoya kunye nezixhobo ze-ultrasonic. Olona nyango lusebenzayo lunikezelwa xa abagwayimbo bengaqhagamshelekanga kwincam ye-actuator kodwa banokuhamba ngokukhululekileyo phakathi kwesixhobo kunye nezinto eziphathwayo. Izixhobo zempembelelo yonyango lwezixhobo kunye nezinto ezidityanisiweyo kunye nogwayimbo olushukumayo olukhululekile olufakwe kwisibambi luyaboniswa. Kwimeko ekubizwa ngokuba yi-intermediate element-striker (s) amandla angama-30-50 N kuphela ayimfuneko kunyango lwezixhobo.
Umbono wecandelo ngezixhobo ezinabagadli abashukumiseka ngokukhululekileyo kunyango lwefuthe lomphezulu.
Ibonisa iseti esemgangathweni yeentloko ezisebenzayo ezinokubuyiselwa kunye nabaqhankqalazi abasebenza ngokukhululekileyo kwizicelo ezahlukeneyo ze-UP.
Iseti yeentloko zokusebenza ezitshintshanayo ze-UP
Ngexesha lonyango lwe-ultrasonic, umhlaseli oscillates kwisithuba esincinci phakathi kokuphela kwetransducer ye-ultrasonic kunye nesampuli ephathwayo, echaphazela indawo ephathwayo. Olu hlobo lweentshukumo eziphezulu zokuhamba / iimpembelelo ngokudibeneyo kunye nokuhamba rhoqo kwamaza okubangelwa zizinto eziphathwayo kubizwa ngokuba yimpembelelo ye-ultrasonic.
Itekhnoloji kunye nezixhobo zeUltrasonic Peening
I-ultrasonic transducer oscillates kwisantya esiphezulu, nge-20-30 kHz eqhelekileyo. I-transducer ye-ultrasonic inokusekelwa kwitekhnoloji ye-piezoelectric okanye ye-magnetostrictive. Nokuba yeyiphi itekhnoloji esetyenzisiweyo, isiphelo sesiphumo se-transducer siya kuscillate, ngesiqhelo nge-20 - 40 mm ngobukhulu. Ngexesha le-oscillation, incam ye-transducer iya kuba nefuthe kubabethi (amanqindi) kumanqanaba ahlukeneyo kumjikelo we-oscillation. Umhlaseli (s) uya kuthi ke achaphazele umphezulu ophathwayo. Iziphumo zempembelelo kuguquko lweplastikhi kumaleko omhlaba wezinto ezibonakalayo. Ezi mpembelelo, ziphindaphindwe amakhulu ukuya kumawaka amaxesha ngomzuzwana, ngokudibeneyo kunye nokuhamba rhoqo kwesantya esinyanzelisiweyo kwinto ephathwayo kubangela inani leziphumo ze-UP.
I-UP yindlela esebenzayo yokunciphisa uxinzelelo lwentsalela eyingozi kunye nokwazisa uxinzelelo lwentsalela yokucinezela kumaleko angaphezulu eendawo kunye nezinto ezidibeneyo.
Kuphuculo lokukhathala, isiphumo sokuxhamla sifezekiswa ikakhulu ngokwazisa uxinzelelo lwentsalela yokuxinana kwimigangatho yesinyithi kunye nealloys, ukwehla koxinzelelo koxinzelelo kwimimandla yeenzwane ze-weld kunye nokuphuculwa kweempawu zomatshini zomaleko womphezulu wezinto.
Ukusetyenziswa kweMizi-mveliso ye-UP
I-UP inokusetyenziswa ngokufanelekileyo ekuphuculeni ukudinwa kobomi ngexesha lokuvelisa, ukulungiswa kunye nokulungiswa kwezinto ezi-welding kunye nolwakhiwo. Itekhnoloji ye-UP kunye nezixhobo zisetyenziswe ngempumelelo kwiiprojekthi ezahlukeneyo zeshishini zokuvuselela kunye nokulungisa i-weld yamalungu kunye nezinto ezi-welding. Iindawo / amashishini apho i-UP isetyenziswe khona ngempumelelo ibandakanya: Iibhulorho zoLoliwe kunye nooHola bendlela, izixhobo zoKwakha, ukwakhiwa kweenqanawa, iMigodi, iZithuthi kunye neAerospace.
