Kugadzira nzira dzealloy simbi chubhu

Forged simbi pombi inogona kupatsanurwa kuita yemahara forging, kugumburisa, extrusion, forging, yakavharwa kufa forging, yakavharwa kushungurudza.Yakavharwa kufa kwekugadzira uye kuvharika kushungurudza nekuti hapana flash, kushandiswa kwezvinhu kwakakwira.Nemaitiro kana akati wandei maitiro anogona kunge akaoma forgings kupedzisa.Sezvo pasina kupenya, nzvimbo yekuumba simba inoderedzwa, mutoro unodiwa unoderedzwa.Cherechedza, zvisinei, haigoni kudziviswa zvachose isina chinhu, izvi zvinofanirwa kudzora zvakanyanya vhoriyamu isina chinhu, kudzora nzvimbo yakaenzana yefogi yekufa uye chiyero chekugadzira, kuedza kuderedza kufa.Orbital inogona kukamurwa kuita forging, swaging swing, roll forging, wedge rolling, ring rolling uye cross rolling nedzimwe nzira.Orbital, isa swaging uye rolling ring zvakare yakashandisa precision forging.

Kuti uvandudze maitiro ekugadzirisa zvinhu zvisati zvashandiswa, roll forging uye rolling inogona kushandiswa sechinhu chakayambuka-refu.Alloy simbi machubhu ane yakafanana rotary forging yemahara forging inoumbwa munharaunda, ine mukana kana ichienzaniswa nehukuru hwefogi, kuumba diki simba pasi pemamiriro ezvinhu anogona kuwanikwa anoumbwa.Nzira dzakadai dzinosanganisira kuumba simbi pombi, kusanganisira yemahara forging, machining zvinhu kuti zviwedzere kubva padyo nemahara epamusoro pevhu, zvakaoma kuve nechokwadi chechokwadi, kuitira kuti kutungamira kwekufamba kwefogi kunofa uye nzira yekugezera inodzorwa nekombuta. inogona kushandisa yakaderera forging simba kuti iwane chimiro chakaoma, yakakwirira chaiyo zvigadzirwa.Semuenzaniso, kugadzirwa kwemhando, hombe-saizi turbine blade forgings.Apo tembiricha yepombi yesimbi inodarika 300-400℃(simbi yebhuruu brittle zone), inosvika 700-800℃, iyo deformation kuramba ichaderedzwa zvakanyanya, iyo deformation inogona zvakare kuvandudzwa zvakanyanya.Forged simbi pombi zvinoenderana nekupisa kwakasiyana mudunhu, kunze kwekuforoma maitiro uye zvinodiwa zvemhando, inogona kupatsanurwa kuita inotonhora, inodziya yekugadzira, inopisa yekuumba matatu ekuumba tembiricha dunhu.Divisheni iyi yaive netembiricha yemhando isina miganhu yakasimba, kazhinji kutaura, kune forging recrystallization tembiricha dunhu rinonzi forging, forging pasina kudziyisa pakamuri tembiricha inonzi inotonhora forging.

Pakutonhora kwakadzika, kuumba, forgings dimensional shanduko idiki.Mumakore 700 anotevera℃kuumba, kushoma oxide kuumbwa, uye hapana pamusoro decarburization.Naizvozvo, chero bedzi simbi pombi deformation simba musimba siyana kuumbwa, kutonhora forging nyore kuwana yakanaka dimensional kunyatsoita uye pamusoro pekupedzisira.Ingodzora tembiricha uye kutonhora kwekuzora, 700℃iyo inotevera inodziya yekugadzira inogonawo kuwana kunaka kwakanaka.Kupisa forging, nekuda kweiyo deformation simba uye deformation kuramba idiki, yakaoma maumbirwo anogona kugadzirwa akakura forgings.Kuti uwane yakakwira dimensional kurongeka kweforgings, mukupisa 900-1000.℃kupisa kwekugadzira nzira.Zvakare, teerera kuvandudza nharaunda yekushanda yeforoma.Forging kufa upenyu (2-5 chiuru forging, inodziya forging 1-2 zviuru gumi, zviuru gumi kutonhora forging 2-5) forging tembiricha siyana kana zvichienzaniswa neimwe ipfupi, asi zviri rusununguko, yakaderera mutengo .

Simbi pombi blank kana kutonhora deformation uye kushanda kuomesa, saka kufa kutsungirira mitoro yakakwirira, saka, zvinoda kushandiswa yakakwirira-simba forging kufa uye kudzivirira kupfeka uye bonded kushandisa zvakaoma lubricating firimu kugadzirisa nzira.Pamusoro pezvo, kudzivirira kutsemuka kwebillet, yepakati annealing kuti ive nechokwadi chekuti zvinodiwa zve deformation kana zvichidikanwa.Kuti uchengetedze mafuta akanaka, iyo isina chinhu inogona kunge iri phosphate kurapwa.Paunenge uchishanda neinoenderera bhaa uye waya tsvimbo, chikamu chazvino hachigone kuomeswa maitiro, chiri kudzidza mukana wekushandisa phosphate lubrication nzira.
