Kugadzirwa kwemachubhu akasiyana-siyana akajeka
Precision pombi imhando yepombi yesimbi isina musono ine hupamhi hwepamusoro uye kupenya kwepamusoro kunogadzirwa nekudhirowa kunotonhora kana kutonhora kukunguruka. Iyo yemukati nekunze dhayamita inogona kuve yakarurama kusvika mukati me 0.2mm. Iyo haingovimbisi chete kukotama uye kusimba kwesimba, asi zvakare ine huremu huremu. Naizvozvo, inoshandiswa zvakanyanya mukugadzirwa kweiyo chaiyo mekiniki zvikamu uye zvimiro zveinjiniya. Iyo inowanzoshandiswa mukugadzirwa kweakasiyana akajairwa zvombo, mbiya, goko, kutakura, nezvimwe.
Zvishandiso zvakajairika 10#, 20#, 35#, 45#, 20Cr, 40Cr, 20CrMo, 16Mn, 27SiMn, 304, 201, 310S, yepamusoro-soro kabhoni structural simbi.
1. Diki dhayamita rekunze.
2. Yakanyanya kurongeka uye inogona kushandiswa padiki kugadzira batch.
3. Zvigadzirwa zvinotonhorwa zvine hunyoro hwepamusoro uye kunaka kwepamusoro.
4. Nzvimbo yemuchinjikwa yepombi yesimbi yakanyanya kuoma.
5.Iyo pombi yesimbi ine basa repamusoro uye dense simbi. Nzira yekuongorora inogona kushandisa mvura ine sipo kupukuta majoini echoto chinopisa kuti uone kana paine kubuda kwemhepo; Pakati pazvo, nzvimbo iyo gasi inonyanya kupukunyuka ndiyo nzvimbo iyo choto chinopisa chinopinda uye chinobuda mupombi. Mhete yekuisa chisimbiso munzvimbo ino inonyanya kupfekwa, saka inofanirwa kuongororwa uye kuchinjwa kazhinji. Iyo process scheme ye pretreatment ye precision simbi pombi isati yatonhora yekukotama inoiswa pamberi; Migumisiro ye normalizing tembiricha, kubata nguva uye kutonhora modhi pane microstructure uye mechanical zvimiro zvepombi yekudya zvakadzidzwa uye kuongororwa; Iyo yakajairwa inojairira maitiro eiyo chaiyo simbi pombi inotemerwa: kupisa tembiricha iri (890 ± 10) ℃, uye yakapararira kutonhora kwemhepo mushure mekubata kwe6min. Yakajairika normalizing process inogona kubvisa zvachose iyo widmanstatten chimiro chechayo simbi pombi, kuita kuti kuenzanirana kwesimba regoho uye kusimba kwesimba kuwedzere kunzwisisika, uye kugadzirisa goho reshiyo reshiyo σ S/b σ ≤ 0.78, elongation 5 δ ≥ 30%, inovandudza zvakanyanya kutonhora kuumba kuita uye kudzivirira kutonhora kukotama kutsemuka. Iyo coefficient yekuwedzera inogona kuratidzwa muhuwandu kana kureba, kazhinji mukureba. Density iyo density yechinhu huremu pachiyero chechikamu chechinhu, mu kg / m3 kana 1B / in3. Iyo yasara tensile stress inonyanya kuuya kubva kune yasara tensile stress inogadzirwa nemidziyo panguva yewelding.
Parizvino, annealing mushure mekupisa kutonhora kunoshandiswa zvakanyanya muinjiniya kubvisa kusara kunetseka, uye post welding kutonhora inzira yakakosha yekusarira kusagadzikana chizvarwa. Iyi nzira haingotambisi simba, asi zvakare inoburitsa hombe welding yakasara kushushikana. Post weld heat treatment ndiyo tekinoroji nyowani yekubvisa kusara kunetseka. Iyo chaiyo simbi pombi ichave yakafayirwa kune yepositi yekupisa kupisa tembiricha isati yaiswa, uye weldment icharamba ichipisa kuchengetedza tembiricha iyi panguva yewelding. Mushure mewelding, inofanira kuiswa insulating nedonje inodzivirira kuti itonhodze zvishoma nezvishoma. Kudzima kunogona kuwedzera simba uye kuoma kwesimbi pombi, asi kuderedza purasitiki yayo. Kudzima zvinhu zvinowanzo shandiswa mukudzima zvinosanganisira mvura, mafuta, alkaline mvura uye munyu. Kupisa kwepombi yesimbi chaiyo kunopisazve pombi yesimbi yakadzimwa kusvika kune imwe tembiricha yobva yaitonhodza neimwe nzira, inonzi tempering. Chinangwa ndechekubvisa kushushikana kwemukati kunogadzirwa nekudzima, kuderedza kuomarara uye brittleness, uye kuwana zvinotarisirwa zvemuchina. Tembiricha yakakamurwa kuita tembiricha yakanyanya, yepakati tembiricha tempering uye yakaderera tembiricha. Tempering inowanzoshandiswa pamwe chete nekudzima uye normalizing. Kudzima uye kudzikamisa kurapwa nzira yekupisa yekupisa yekupisa tembiricha mushure mekudzima inonzi quenching uye tempering kurapwa.
