Ukulinganisa kweHot Forging

Ithunyelwe nguAdmin

I-Hot Forging yinkqubo yokwenza esetyenziselwa ukuvelisa iindidi zentsimbi,kuquka iimoto kunye nezixhobo ze-aerospace.Ikho ukususela kwinkulungwane yamashumi amabini.Nangona kunjalo, kukho inani lezinto ekufuneka zithathelwe ingqalelo xa kuyilwa inkqubo eshushu yokubumba.Oku kubandakanya ukunyanzeliswa kwezinto, ukuhanjiswa kweqondo lokushisa kunye nomphumo weidrafti.Ngaphezu koko, i-microstructure yecandelo elibunjiweyo kufuneka ibalwe ngokufanelekileyo.Ukubunjwa okushushu kubandakanya amaqondo obushushu aphezuluezikhokelela kutshintsho olubalulekileyo lwesakhiwo somphezulu wendawo yomsebenzi.Ukongeza koku, inkqubo yokubumba inokubangela ukubunjwa kweendawo ezine-oxidized.Inkqubo yokubumba isoloko isetyenziselwa ukuvelisa iinxalenye ezinejiyometri ezintsonkothileyo ze-3D.Ke ngoko, ukuchaneka kwemodeli kubalulekile ekufaniseni okuyimpumelelo.Ngokuqhelekileyo, iintlobo ezintathu zeendlela zokulinganisa zisetyenziselwa ukulinganisa inkqubo: ubuchule be-FE (Fuzzy EM), ukulandelwa ngasemva, kunye nesici esilinganiselwe.I-Hot forging yinkqubo ebalulekileyo yokwenziwa kwezinto ezikhuselekileyo zokhuseleko.Oku kungenxa yokuba yenza ukubunjwa kweendawo zetsimbi ezinomthwalo ophezulu wokusebenza.Ekubeni iqondo lobushushu liphezulu ngokwentelekiso, linokwenza ukuba kwenziwe isinyithi esithambileyo nesikwaziyo ukumelana nokonakala.Kukho iindidi ezimbini eziphambili zokubunjwa: ukubunjwa okuvulekileyo kunye nevenkile yomatshini.Izibonelelo zokubumba eziqhelekileyo zinokusuka kwishumi leemilimitha ukuya kwiimilimitha ezininzi.Ngenxa yoko, ukungafani phakathi kokufa kunokubangela iingxaki ezinkulu.Ngokuxhomekeke kuhlobo lwemathiriyeli eyenziweyo, iintlobo ezahlukeneyo zokufa zinokufuneka.Kwakhona, i-forging eshushu inokufuna amanyathelo ongezelelweyo okusebenza, njengonyango lokushisa okanye ukugqiba.Ngaphandle kokubaluleka kwayo, ukubumba okushushu akuchanekanga njengokubumba okubandayo.Oku kungenxa yokuba ukwandiswa kwe-thermal yezinto eziphathekayo ngexesha lenkqubo yokubumba kunokuchaphazela ukuchaneka kwemveliso egqityiweyo.Ngaphezu koko, ukusetyenziswa kokuhanjiswa kweqondo lokushisa okungafaniyo kunokuvelisa utshintsho olubalulekileyo kwi-microstructure yecandelo elibunjiweyo.Ngaloo ndlela, kubaluleke kakhulu ukuqinisekisa ukuba isinyithi esibunjiweyo sinamandla afunekayo kunye nokuqina.Ukuze kulinganiswe inkqubo yokubumba,iindlela ezintathu ezisisiseko zemodeli kufuneka zisetyenziswe.Okokuqala, indlela yento elinganiselweyo ingasetyenziselwa ukulinganisa inkqubo yokubumba.Okwesibini, indlela ye-FE ingasetyenziselwa ukumisela ukuhanjiswa kweqondo lokushisa kwindawo edibeneyo.Okokugqibela, ubuchule bokulandela umkhondo obungasemva bunokusetyenziswa ukuyila inkqubo yokubumba eshushu.Ukuze ubale unikezelo oluchanekileyo lobushushu,inkqubo yokubunjwa kufuneka yenziwe ngendlela elawulwayo.Oku kungenxa yokuba kubalulekile ukuqwalasela iidrafti kunye nokugudiswa kweencam ezibukhali.Ukongezelela, ukusetyenziswa kwezinto ezikhethekileyo zokufa ezinokumelana nokushisa okuphezulu kuyacetyiswa.Omnye umba oza kuqwalaselwa kukukhethwa komatshini wokwenza.Ukukhetha umatshini ochanekileyo unempembelelo enkulu ekuhanjisweni kweqondo lokushisa kwecandelo elibunjiweyo.Okokugqibela, kubalulekile ukuthathela ingqalelo ixesha lokugcinwa kunye nokuthutha.Ukumisela iqondo lokushisa elifanelekileyo lokubumba, ubuninzi obukhoyo obukhoyo obusebenzayo busetyenziswa.Ngexesha lenkqubo, i-forging die ixhomekeke kwimithwalo ephezulu yomatshini kunye neekhemikhali.Ngale mithwalo, ukufa kufuneka kumelane noluhlu olubanzi lweenguqu ze-thermal kunye neekhemikhali.Ngaphezu koko, kukho uxinzelelo olubalulekileyo lwentsalela.
