zvinhu 40cr

40Cr ndiyo GB yakajairika simbi nhamba muChina, uye 40Cr simbi ndeimwe yeanonyanya kushandiswa simbi muindasitiri yekugadzira michina.Iine yakanaka yakazara michina michanicha, yakanaka yakaderera tembiricha inokanganisa kusimba uye yakaderera notch sensitivity.Kuomarara kwesimbi, kana mvura inodzima kuoma kusvika Ф 28 ~ 60 mm, apo oiri kudzima 40 mm kuomarara kwakakodzerawo Ф 5 mm . cyanidation uye high frequency quenching.Kana kuoma kuri 174 ~ 229HB, iyo hama machinability ndeye 60%.Simbi inokodzera kugadzira svikiro - saizi yepurasitiki molds.

Medium carbon tempered steel, inotonhora heading die steel.Simbi ndeyemutengo wakadzikama, iri nyore kugadzirisa uye inogona kuwana kumwe kuoma, plasticity uye abrasion resistance mushure mekunyatsopisa kupisa.Normalizing inogona kuvandudza kucheka kwekuita kwechinhu chisina chinhu kuburikidza nekusimudzira microstructure refinement uye kusvika kune equilibrium state.Inopisa pa550 ~ 570 ℃ yakakwira kupfuura 45 simbi, inokodzera kukwirisa frequency kudzima, kudzima murazvo uye kumwe kuoma kwepasi kurapwa.

Shaft zvikamu ndechimwe chezvakajairika zvikamu zvinowanzosangana mumashini.Inonyanya kushandiswa kutsigira zvinhu zvekufambisa, kuendesa torque uye mutoro.Shaft zvikamu zvinotenderera nhengo dzemuviri, kureba kwacho kwakakura kupfuura dhayamita, kazhinji inoumbwa neiyo concentric shaft cylindrical surface, conical surface, mukati gomba uye shinda uye inoenderana yekupedzisira nzvimbo. Zvinoenderana neiyo shaft dhizaini inogona kukamurwa kuita nhanho nhanho dzakasiyana. shaft, hollow shaft uye crankshaft.

40Cr chinhu chakajairika chezvikamu zveshaft. Iyo yakachipa uye inogona kuwana zvirinani kucheka mashandiro mushure mekudzima uye kudziya (kana normalizing), uye inogona kuwana yakakwirira yakazara yakazara mechanicha zvinhu zvakaita sesimba uye kuoma. Mushure mekudzima, kuoma kwepamusoro kunogona kusvika 45 ~ 52HRC.

40Cr inoshandiswa zvakanyanya mukugadzira michina. Iri rudzi rwesimbi ine yakanaka mechanical properties.Iyi isimbi yepakati kabhoni alloy simbi ine yakanaka quenching performance, 40Cr inogona kuomeswa kusvika HRC45 ~ 52. Naizvozvo, kana kuomarara kwepamusoro kuchida kuvandudzwa uye iyo yepamusoro michina ye40Cr inotarisirwa kuiswa mukutamba, iyo yepamusoro-frequency quenching kuita, iyo 40Cr inotarisirwa kuomeswa mushure mekuoma kwe40Cr. 55-58hrc, kuitira kuti uwane iyo inodiwa yakakwirira yepamusoro kuoma uye kuchengetedza kunaka kuoma kwemoyo.
