Iindlela zokuvelisaityhubhu yentsimbi yengxubevange

Umbhobho wensimbi owenziweyo unokwahlulwa ube yi-forging yamahhala, ukuphazamisa, i-extrusion, i-forging, i-forging die evaliweyo, i-upsetting evaliweyo.Ukuvala ukufa kunye nokuphazamiseka okuvaliweyo ngenxa yokuba akukho flash, ukusetyenziswa kwezinto eziphathekayo kuphezulu.Ngenkqubo okanye iinkqubo ezininzi kunokuba nzima ukuqulunqa ukugqiba.Ekubeni akukho flash, indawo yamandla okubumba iyancitshiswa, umthwalo ofunekayo uyancitshiswa.Qaphela, nangona kunjalo, ayinakuthintelwa ingenanto ngokupheleleyo, oku kufuneka kulawule ngokungqongqo umthamo wesithuba esingenanto, ukulawula indawo ehambelanayo yokufa kunye nokulinganisa ukulinganisa, imizamo yokunciphisa ukuguga.I-Orbital inokohlulwa ibe yi forging, swaging swing, roll forging, wedge rolling, ring rolling and cross rolling nezinye iindlela.I-Orbital, ifake i-swaging kunye ne-rolling ring nayo isetyenziselwe ukubunjwa okuchanekileyo.

Ukuze kuphuculwe iinkqubo zokusetyenzwa phambi kokusetyenziswa kwemathiriyeli, i-roll forging and rolling ingasetyenziswa njengento enqamlezileyo.Iityhubhu zentsimbi ye-alloy kunye ne-rotary forging forging free forging yenziwa kwindawo, inenzuzo xa kuthelekiswa nobukhulu bokubumba, ukubumba amandla amancinci phantsi kweemeko kunokufezekiswa.Ezo ndlela zibandakanya ukubumba umbhobho wentsimbi, kubandakanywa ukubumba simahla, izinto zokulungisa ukunwebeka ukusuka kufutshane nobuso obukhululekileyo bomphezulu wokungunda, kunzima ukuqinisekisa ukuchaneka, ukuze ulwalathiso lwentshukumo yokubunjwa lufe kunye nenkqubo yokugungqa elawulwa yikhompyuter, inokusebenzisa amandla asezantsi okubumba ukufumana imilo entsonkothileyo, iimveliso ezichanekileyo.Umzekelo, ukuveliswa kweentlobo ezahlukeneyo, ubungakanani obukhulu be-turbine blade forgings.Xa ukushisa kombhobho wensimbi kudlula i-300-400℃(i-steel blue brittle zone), ifikelela kwi-700-800℃, ukuchasana kwe-deformation kuya kuncitshiswa kakhulu, i-deformation inokuphuculwa kakhulu.Umbhobho wentsimbi owenziweyo ngokwamaqondo obushushu ahlukeneyo kulo mmandla, ngaphandle kwenkqubo yokubumba kunye neemfuno zomgangatho, inokwahlulwa ibe yindawo ebandayo, efudumeleyo, eshushu yokubumba imimandla emithathu yobushushu.Olu lwahlulo lwalunoluhlu lweqondo lobushushu olungenamida engqongqo, ngokuqhelekileyo, kukho ummandla wokufudumala wecrystallization obizwa ngokuba yi-forging, ukukhwabanisa ngaphandle kokufudumeza kwiqondo lokushisa elibizwa ngokubanda.

Kumaqondo obushushu aphantsi ukubunjwa, i-forging dimensional utshintsho luncinci.Kwi-700 elandelayo℃ukubumba, ukubunjwa kwe-oxide encinci, kwaye akukho decarburization yomhlaba.Ngoko ke, okoko nje umbhobho wentsimbi deformation amandla kuluhlu lwamandla ukubumba, ukubanda abandayo lula ukufumana ukuchaneka elungileyo dimensional kunye nokugqiba umphezulu.Lawula nje ubushushu kunye nokupholisa ukuthambisa, 700℃oku kubumba okufudumeleyo kulandelayo kunokufumana ukuchaneka okuhle.I-Hot forging, ngenxa ye-deformation yamandla kunye nokumelana ne-deformation zincinci, iimilo ezintsonkothileyo zinokubunjwa ezinkulu.Ukufumana ukuchaneka okuphezulu komgangatho wokubumba, kwiqondo lobushushu le-900-1000℃inkqubo yokubumba eshushu.Kwakhona, nikela ingqalelo ekuphuculeni indawo yokusebenza yokubumba.Forging die life (2-5 iwaka elikhohlisayo, ukufudumala ukubumba 1-2 ishumi lamawaka, ishumi lamawaka elibandayo elibandayo 2-5) uluhlu lobushushu bokubumba xa kuthelekiswa nolunye lufutshane, kodwa inkululeko, ixabiso eliphantsi .

Steel umbhobho blank xa deformation ebandayo kunye nomsebenzi ukuqina, ngoko kufa ukumelana nemithwalo ephezulu, ngoko ke, kufuna ukusetyenziswa high-amandla forging die kunye nokuthintela ukunxitywa kunye ebotshiweyo usebenzisa indlela yokuthambisa nzima yokuthambisa film.Ukongeza, ukuthintela i-billet crack, annealing intermediate ukuqinisekisa ukuba iimfuno deformation xa kuyimfuneko.Ukuze kugcinwe ukuthambisa okulungileyo, indawo engenanto isenokuba lunyango lwephosphate.Xa usebenza nge-bar eqhubekayo kunye nentonga yocingo, icandelo langoku alikwazi ukuthambisa inkqubo, lifunda ithuba lokusebenzisa indlela ye-phosphate lubrication.
