④ Inoshandiswa kugadzira maconvex molds, concave molds, uye kuisa zvidhinha zvinoda kupfekeka kwepamusoro uye zvimiro zvakaoma mukupeta.Zvinokurudzirwa kuve nekuoma kwe60-64HRC paunenge uchigadzira maconvex molds, uye 60-64HRC pakugadzira maconcave molds.
⑤ Nekugadzira inotonhora extrusion inofa uye inofa yealuminium zvikamu, zvinokurudzirwa kuve nekuoma kwe60-62HRC pakugadzira iyo inofa, uye 62-64HRC pakugadzira iyo inofa.
⑥ Zvinokurudzirwa kushandisa kuoma kwe62 ~ 64HRC kune convex uye concave molds inoshandiswa kugadzira copper inotonhora extrusion molds.
⑦ The convex uye concave molds inoshandiswa simbi inotonhora extrusion molds inokurudzirwa kuva nekuoma kwe62 ~ 64HRC.
⑧ Chitubu chesimbi mahwendefa ane chikamu chikuru che 0.65% ~ 0.80% anoshandiswa kugadzira kabhoni ane kuomarara kwe37 ~ 42HRC, achipa hupenyu hunosvika 150000 kutenderera.
⑨ Chitubu mahwendefa ane chikamu chikuru che 0.65% kusvika 0.80% anoshandiswa kugadzira kabhoni ane kuomarara kwe37-42HRC, uye nekuwedzera nitriding kurapwa, hupenyu hwavo hwesevhisi hunogona kusvika 400000 nguva.
Ⅲ-Kugadziriswa kweCr12MoV Cold Working Die Steel:
Tsanangudzo yekunyorovesa yechando extrusion mold: Chengetedza uye kupisa mold nesimbi mafirita patembiricha ye760-780 ℃ kwemaawa gumi, nekutonhora kwechoto uye kuoma kwe196HBW.Cold extrusion kuumba inogona kuwanikwa zvakanaka.
Tsanangudzo yeyakajairwa isothermal spheroidizing annealing: 850-870 ℃ × 3-4 maawa, yakanyoroveswa muchoto kusvika 740-760 ℃ × 4-5 maawa ekurapa isothermal, nemhepo inotonhora kuoma ≤ 241HBW, giredhi optimal ℃ carbide isothermal. tembiricha 740-76o ℃, uye nguva ≥ maawa 4-5.
Tsanangudzo ye spheroidizing annealing: (860 ± 10) ℃ × 2-4 maawa, kutonhora kwechoto pamwero wekutonhora we30 ℃/awa, (740 ± 10) ° C x 4-6 maawa, kutonhora zvishoma nezvishoma kusvika 500-600 ℃ ne choto, kutonhora kwemhepo mushure mekubuda, kuoma 207-255HBW.
General kudzima uye kudzikisira zvirevo: kudzima tembiricha 1000-1050 ℃, kudzima mafuta kana kudzima, kuomarara 260HRC, kupisa tembiricha 160-180, nguva yekupisa maawa maviri, kana kupisa tembiricha 325-375 ° C, kudziya 2-3 nguva.
Kudzimisa kwakadzika uye kuderera kwekudzoka kwekudzima tembiricha: 950 ℃ -1040 ℃, tembiricha yekudziya inotenderera 200 ℃, yechipiri kupisa.
Kudzimisa kwakanyanya uye kwakakwira kudzoka kwekudzima tembiricha: 1050-1100 ℃, tembiricha yekudziya inotenderedza 520 ℃, yechipiri kupisa.Iyo yechipiri yekuomesa nzira inoshandiswa pakudzima kwepamusoro uye kudzokorodza zvakanyanya inovandudza kuoma, asi zviyo zvinokura.
Cryogenic kurapwa: Cr12MoV simbi inorapwa cryogenic, iyo inogona kukonzeresa yakanyanya kupararira ultrafine carbides kubva kukadzimwa martensite, uyezve aya emhando yepamusoro carbides anogona kushandurwa kuita carbides mushure me200 ℃ yakaderera-tembiricha kudziya.Iyo martensite isina cryogenic kurapwa inongokonzeresa shoma shoma yecarbide mune dzimwe nzvimbo dzenzvimbo mushure mekushomeka kwekushisa kwemoto.
zhongao inotora yakaderera-kupisa kemikari kupisa kupisa nzira, iyo inochengetedza kuomarara kwepamusoro uye kupfeka kuramba 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 zhongao's Cr12MoV midziyo yesimbi isina tsvina, mushure mekurapa gasi nitrocarburization, inosvika pamusoro pezvimedu mazana matatu, iyo inodarika ka10 nguva yakareba kupfuura iyo yemhando dzakafanana dzakabatwa neyakajairwa kudzimwa uye kupisa.
