Ⅰ-ChiiCr12MoV Kutonhora Kushanda Die Steel
Iyo Cr12MoV inotonhora inoshanda die simbi inogadzirwa naJinbaicheng ndeye chikamu chepamusoro kupfeka-resistant micro deformation tool simbi, iyo inoratidzwa nekukwirira kupfeka kuramba, kuoma, micro deformation, kusimba kwekushisa kwepamusoro, simba rekukotama, uye zvimwe zvinhu.Iyo yechipiri chete kune yakakwirira-kumhanya simbi uye yakakosha zvinhu zvekutsika, inotonhora musoro, uye zvimwe zvinhu.Cr12MoV die simbi ndeye kabhoni molybdenum ledeburite simbi ine yakaderera kabhoni yemukati pane Crl2 simbi.Molybdenum uye vanadium inowedzerwa kuvandudza kupisa kwekushanda, kukanganisa kuoma uye kugovera carbide kwesimbi.Cr12MoV die simbi ine yakaderera kabhoni yemukati pane Cr12 die simbi.Kuwedzerwa kwezvinhu zvitsva zvealloy kunovandudza chiitiko che carbide isina kuenzana.Uyezve, molybdenum uye molybdenum inogona kuderedza kuparadzaniswa kwecarbide uye kunatsiridza kuoma.Vanadium uye vanadium inogona kunatsa zviyo uye kuwedzera kuomarara, Naizvozvo, Jin Baicheng's Cr12MoV mold simbi ine yakanyanya kuomarara, ine muchinjiko-chikamu pazasi 400mm iyo inogona kudzimwa zvachose, uye inogona kuramba yakaomarara kuoma uye kupfeka kuramba pa300-400.℃. Besides, Jinbaicheng's Cr12MoV mold simbi ine kusimba kuri nani pane zvimwe zvinhu zvegiredhi rimwe chete mumusika wepasirese, uye mukana wekuchinja kwevhoriyamu panguva yekudzima wakaderedzwa zvakanyanya.Naizvozvo, kukwirira kwayo kupfeka kuramba uye kunaka kwakazara kwemagetsi zvivakwa kunoita kuti Jinbaicheng's Cr12MoV mold simbi inyatsokodzera kugadzira molds dzakasiyana siyana dzakakura muchinjiko-chikamu, chimiro chakaomarara, uye kushingirira mikuru mikuru, pamwe neakasiyana-siyana anotonhora maturusi pasi pemamiriro ekushanda anorema, senge. kubaya kunofa, kuchekerera kunofa, kukunguruka kunofa, etc Simbi ndiro yakadzika dhizaini inofa, denderedzwa saw, maturusi akajairwa uye maturusi ekuyeresa, shinda inotenderedza kufa, nezvimwe.
Ⅱ-Nhungamiro Yekushandisa of Cr12MoV Kutonhora Kushanda Die Steel
①Cr12MoV inogona kushandiswa kugadzira zvimiro zvakaoma zveconvex, concave, uye kuisa zvivharo zvekubaya mold nehukobvu hwezvinhu> 3mm.Zvinokurudzirwa kuve nekuoma kwe58 ~ 62HRC pakugadzira maconvex molds uye 60 ~ 64HRC pakugadzira maconcave molds.
②Nekugadzirwa kwe punch uye concave molds inoda kukwirira kupfeka kusagadzikana, zvinokurudzirwa kuva nekuoma kwe60 ~ 62HRC paunenge uchiita punch uye 62 ~ 64HRC paunenge uchiita concave mold.
③Pakugadzirwa kwekusapfeka-resistant concave molds mune yakadzika yekudhirowa mold, zvinokurudzirwa kuve nekuoma kwe62 ~ 64HRC.
④Inoshandiswa kugadzira maconvex molds, concave molds, uye kuisa zvivharo zvinoda kupfekedzwa kwepamusoro uye zvimiro zvakaoma mukupeta.Zvinokurudzirwa kuve nekuoma kwe60-64HRC paunenge uchigadzira maconvex molds, uye 60-64HRC pakugadzira maconcave molds.
⑤Kugadzira iyo inotonhora extrusion inofa uye inofira zvikamu zvealuminium, zvinokurudzirwa kuve nekuoma kwe60-62HRC pakugadzira iyo inofa, uye 62-64HRC pakugadzira iyo inofa.
⑥Zvinokurudzirwa kushandisa kuoma kwe62 ~ 64HRC kune convex uye concave molds inoshandiswa kugadzira copper inotonhora extrusion molds.
⑦Iyo convex uye concave molds inoshandiswa simbi inotonhora extrusion molds inokurudzirwa kuve nekuoma kwe62 ~ 64HRC.
⑧Mapureti esimbi echitubu ane chikamu chikuru che 0.65% ~ 0.80% anoshandiswa kugadzira kabhoni ane kuomarara kwe37 ~ 42HRC, achipa hupenyu hunosvika 150000 kutenderera.
⑨Mapureti esimbi echitubu ane chidimbu chechikamu che 0.65% kusvika 0.80% anoshandiswa kugadzira kabhoni ane kuoma kwe37-42HRC, uye nekuwedzera nitriding kurapwa, hupenyu hwavo hwesevhisi hunogona kusvika 400000 nguva.
Ⅲ-Processing of Cr12MoV Cold Working Die Steel:
Tsanangudzo yekunyorovesa yechando extrusion mold: Chengetedza uye kupisa mold nesimbi filings pakupisa kwe760-780.℃kwemaawa gumi, nekutonhora kwechoto uye kuoma kwe196HBW.Cold extrusion kuumba inogona kuwanikwa zvakanaka.
Tsanangudzo yeyakajairwa isothermal spheroidizing annealing: 850-870℃ ×Maawa 3-4, yakanyoroveswa muchoto kusvika 740-760℃ ×Maawa 4-5 ekurapa isothermal, nemhepo inotonhora kuoma≤241HBW, eutectic carbide giredhi≤3, yakakwana isothermal tembiricha 740-76o℃, uye nguva≥4-5 maawa.
Tsanangudzo ye spheroidizing annealing: (860± 10)℃ ×2-4 maawa, choto ichitonhora pamwero wekutonhora we30℃/ awa, (740± 10)° C x 4-6 maawa, zvishoma nezvishoma kutonhora kusvika ku500-600℃nechoto, kutonhora kwemhepo mushure mekubuda, kuoma 207-255HBW.
General quenching uye tempering tsanangudzo: quenching tembiricha 1000-1050℃, kudzima mafuta kana kudzima, kuoma 260HRC, kupisa tembiricha 160-180, nguva yekupisa maawa maviri, kana kupisa tembiricha 325-375° C, kupisa 2-3 nguva.
Kudzimisa kwakaderera uye kwakaderera kudzoka kwekudzima tembiricha: 950℃-1040℃, tembiricha yekudziya inenge 200℃, kushatirwa kwechipiri.
High quenching uye yakakwirira kudzoka quenching tembiricha: 1050-1100℃, tembiricha yekudziya inosvika 520℃, kushatirwa kwechipiri.Iyo yechipiri yekuomesa nzira inoshandiswa pakudzima kwepamusoro uye kudzokorodza zvakanyanya inovandudza kuoma, asi zviyo zvinokura.
Cryogenic kurapwa: Cr12MoV simbi inobata cryogenic kurapwa, iyo inogona kukonzeresa yakanyanya kuparadzirwa ultrafine carbides kubva quenched martensite, uye ipapo aya ekupedzisira carbides anogona kushandurwa kuita carbides mushure me200.℃kudzikira-kupisa.Iyo martensite isina cryogenic kurapwa inongokonzeresa shoma shoma yecarbide mune dzimwe nzvimbo dzenzvimbo mushure mekushomeka kwekushisa kwemoto.
Jinbaicheng anotora yakaderera-kupisa kemikari kupisa nzira yekurapa, iyo inochengetedza kuomarara kwepamusoro uye kupfeka kusagadzikana kweCr12MoV simbi.Matatu anowanzo shandiswa yakaderera-tembiricha yemakemikari kupisa ekurapa maseru, anoti ion nitriding, gasi nitrocarburizing, uye munyu yekugezera sulfur cyanide co nitriding, ine yakakosha kupikisa uye kunamatira, ine munyu yekugezera sulfur cyanide co nitriding iriyo yakanyanya kunaka.
Hupenyu hwesevhisi hwekudhirowa hunofira Jinbaicheng's Cr12MoV midziyo yesimbi isina tsvina, mushure mekurapwa kwegasi nitrocarburization, inosvika pamusoro pe30000 zvimedu, iyo inodarika kakapetwa ka10 kupfuura iyo yemhando dzakafanana dzakabatwa neyakajairwa kudzimwa uye kupisa.
