Uvavanyo lwe-Ultrasonic yindlela esetyenziswa ngokuqhelekileyo yokukhangela iziphene zangaphakathi zangaphakathi kwi-cylindrical forgings. Ukuze kuqinisekiswe iziphumo zovavanyo olusebenzayo, kukho imiqathango ebalulekileyo ekufuneka ilandelwe.
Okokuqala, uvavanyo lwe-ultrasonic kufuneka lwenziwe kwi-cylindrical forgings emva konyango lokugqibela lwe-austenitizing kunye nobushushu bobushushu bonyango ukuze kufumaneke iipropathi ze-mechanical forgings. Ewe, njengoko kufuneka, uvavanyo lunokwenziwa ngaphambi okanye emva kwalo naluphi na uxinzelelo olulandelayo oluthomalalisa unyango lobushushu.
Okwesibini, xa uqhuba uvavanyo lwe-ultrasonic, i-radial incidence ultrasonic beam kufuneka isetyenziswe ukuskena okubanzi. Oku kuthetha ukuba amaza e-ultrasonic kufuneka abe yisiganeko se-perpendicular kwi-surface yangaphakathi ukusuka kwi-probe ukuqinisekisa ukubonwa kwendawo yonke yangaphakathi. Ngeli xesha, ukuze kuphuculwe ukuchaneka kokubhaqwa, kufuneka kubekho ubuncikane be-20% edityanisiweyo yobubanzi betshiphu yeprobe phakathi kokuskena okukufutshane.
Ukongeza, i-forgings ingaba kwimeko yokumisa okanye ihlolwe ngokuyibeka kwi-lathe okanye i-roller ukuze ijikeleze. Oku kuqinisekisa ukuba wonke umphezulu wangaphakathi ufumana ukhuseleko olwaneleyo.
Ngexesha lenkqubo yokuhlola ethile, ingqalelo kufuneka ihlawulwe kubuchule kunye nokucoceka kwendawo yangaphakathi yokubumba. Umphezulu akufanele ube ne-scratches, isikhumba se-oxide esikhululekile, i-debris, okanye ezinye izinto zangaphandle ukuthintela ukuphazamiseka ekusasazeni kunye nokwamkelwa kwamaza e-ultrasonic. Ukufezekisa oku, kuyimfuneko ukusebenzisa i-agent yokudibanisa ukudibanisa ngokuqinileyo i-probe kwindawo yangaphakathi ye-forging ukuqinisekisa ukuhanjiswa okusebenzayo kwe-ultrasonic.
Ngokumalunga nezixhobo, izixhobo zovavanyo lwe-ultrasonic ziquka izixhobo zovavanyo lwe-ultrasonic, iiprobes, ii-agent zokudibanisa, kunye neebhloko zovavanyo. Ezi zixhobo zingundoqo ekuqinisekiseni ukuchaneka kunye nokuthembeka kwenkqubo yokuvavanya.
Ekugqibeleni, xa uqhuba uvavanyo lwe-ultrasonic, ukwamkelwa kwe-forgings kunokugwetywa ngokusekelwe kwinani leziphene, i-defect amplitude, isikhundla, okanye ukudibanisa kwezi zintathu, njengoko kufuneka. Okwangoku, ngenxa yobukho beekona ezijikelezileyo kunye nezinye izizathu zemilo yendawo kwinqanaba le-cylindrical forgings, akuyimfuneko ukuhlola iindawo ezincinci zomngxunya wangaphakathi.
Isishwankathelo, uvavanyo lwe-ultrasonic yindlela ethembekileyo yokufumanisa iziphene zangaphakathi zangaphakathi kwi-cylindrical forgings. Ukulandela izilumkiso ezingentla, ezidityaniswe nezixhobo ezifanelekileyo kunye neteknoloji, inokuqinisekisa umgangatho kunye nokuthembeka kwe-forgings kunye nokuhlangabezana neemfuno zovavanyo oluhambelanayo.
