Chii kuumba
Forging inzira yekugadzira zvinhu nekudziisa simbi kune yepurasitiki mamiriro uye kushandisa simba kuumba zvinhu. Izvi zvinobvumira kuti zvinhu zvipfurwe, compressed, kana kuti yakatambanudzwa muchimiro chaidiwa. Kugadzira kunogona kubvisa hurema hwakadai sekukanda porosity inogadzirwa panguva yemetallurgical process, gadzirisa iyo microstructure, uye nekuti iyo yakazara simbi inoyerera inochengetedzwa, iwo ma mechanic properties ye forgings anowanzo kurira kune ayo ekukandwa kwechinhu chimwe chete.
Kutanga kwesimbi recrystallization tembiricha inenge 727 ℃, asi 800 ℃ inowanzoshandiswa semutsetse wekuparadzanisa. Pamusoro pe800 ℃ iri kupisa kuumba; pakati pe300-800 ℃ inodaidzwa kudziya kwekuforoma kana semi-hot forging, uye kuforoma pakamuri tembiricha inonzi cold forging.
Kugadzirwa kwezvikamu zvine chokuita nekusimudza zvinowanzoshandisa kupisa kunopisa.
Forging process
Matanho ekugadzira anopisa ekugadzira mabhoti ari: kucheka → kupisa (kuramba waya kudziyisa) → kuumba → kubaya → kuchekerera → kupfura kuputika → shinda → galvanizing → kuchenesa waya
Kucheka: Cheka bhora rakatenderera kuita hurefu hwakakodzera
Kupisa: Pisai bhara rakatenderedzwa kumamiriro epurasitiki nekudziisa waya
Forging: Shandura chimiro chechinhu nechisimba pasi pesimba re mold
Kubhowa: Gadzira gomba repakati pakati peworkpiece
Trimming: Bvisa zvinhu zvakawandisa
Shot blasting: Bvisa burrs, kuwedzera kupera kwepamusoro, kuwedzera roughness, uye kufambisa galvanizing
Threading: Gadzirisa tambo
Galvanizing: Wedzera kuramba ngura
Kuchenesa waya: Mushure mekuita galvanizing, panogona kunge paine zinc slag yasara mushinda. Iyi nzira inochenesa tambo uye inovimbisa kusimba.
Zvimiro zvezvikamu zvefodya
Kuenzaniswa nemitambo, simbi yakagadziridzwa nekugadzira inogona kuvandudza microstructure yayo uye michina zvinhu. Mushure mekugadzira nzira inopisa kushanda deformation yekukanda chimiro, nekuda kwekushanduka uye recrystallization yesimbi, iyo yepakutanga coarse dendrite uye columnar zviyo zvinova zviyo zviri nani uye zvakagovaniswa zvakaenzana ne equiaxed recrystallized chimiro.. Kuparadzaniswa kwepakutanga, kusununguka, pores, uye inclusions muingot yesimbi inobatanidzwa uye inosungirirwa nekumanikidzwa, uye chimiro chavo chinova chakanyanya compact, iyo inovandudza simbi yepurasitiki uye michina.
Iyo mechanical properties yecastings yakaderera pane iyo yekugadzira zvinhu zvakafanana. Pamusoro pe, forging processing inogona kuve nechokwadi kuenderera kwesimbi fiber chimiro, kuitira kuti chimiro chefiber chekugadzira chienderane nechimiro chekugadzira, uye tambo yesimbi inoyerera haina kusimba, iyo inogona kuve nechokwadi chekuti zvikamu zvine yakanaka mechanical properties uye hupenyu hurefu hwebasa. Forgings inogadzirwa ne precision forging, chando extrusion, uye inodziya extrusion maitiro haakwanise kuenzaniswa nekukanda.
Forgings zvinhu zvakaumbwa nekuisa kumanikidza kusimbi kuburikidza nepurasitiki deformation kuti isangane nechimiro chinodiwa kana yakakodzera kumanikidza simba.. Rudzi urwu rwesimba rinowanzo kuwanikwa uchishandisa simbi simbi kana kumanikidza. Iyo yekuumba maitiro inovaka yakapfava zviyo chimiro uye inovandudza chimiro chemuviri chesimbi. Mukushandiswa chaiko kwezvikamu, dhizaini yakakodzera inogona kuita kuti zviyo zviyerere munzira yekumanikidza kukuru. Castings zvinhu zvakaita sesimbi zvinowanikwa nenzira dzakasiyana dzekukanda, nemamwe manzwi, iyo yakanyungudutswa simbi yesimbi inoiswa muforoma yakagadzirwa nekudurura, pressure injection, kuyamwa, kana dzimwe nzira dzekukandira, uye mushure mekutonhora, chinhu chawanwa chine chimiro chakati, saizi, uye kuita mushure mekuchenesa uye mushure mekugadzirisa, etc.
Kushandiswa kwezvikamu zvefodya
Kugadzira kugadzira ndiyo imwe yenzira huru dzekugadzirisa iyo inopa hutsinye machining ezvikamu zvemakanika muindasitiri yekugadzira michina. Nokugadzira, kwete chete chimiro chezvikamu zvemakanika kuwanikwa, asi chimiro chemukati chesimbi chinogonawo kuvandudzwa, uye ma mechanical properties uye zvinhu zvemuviri zvesimbi zvinogona kuvandudzwa. Kugadzira nzira dzekugadzira dzinonyanya kushandiswa kugadzira akakosha mekiniki zvikamu zvinoiswa pasi pemasimba makuru uye zvine zvakakwirira zvinodiwa. Semuyenzaniso, steam turbine generator shafts, rotors, impellers, blades, machira, hombe hydraulic press columns, high-pressure cylinders, rolling mill rolls, mukati combustion injini cranks, matanda ekubatanidza, gears, ma bearings, uye zvikamu zvakakosha muindasitiri yedziviriro yenyika senge artillery zvese zvinogadzirwa nekugadzira.
Naizvozvo, kugadzirwa kwekugadzira kunoshandiswa zvakanyanya mune metallurgical, kuchera, motokari, tarakita, michina yekukohwa, peturu, makemikari, ndege, aerospace, zvombo, nemamwe maindasitiri emaindasitiri. Muhupenyu hwezuva nezuva, kugadzira kugadzira zvakare kunotora chinzvimbo chakakosha.
Kana iwe uine mumwe mubvunzo nezve kugadzirwa kwemabhoti, pls inzwa kuti utaure nesu.
