impahla 40cr

I-40Cr iyinombolo yensimbi evamile ye-GB e-China, futhi insimbi engu-40Cr ingenye yensimbi esetshenziswa kakhulu embonini yokukhiqiza imishini. Inezakhiwo ezinhle ezibanzi zemishini, ukuqina okuhle komthelela wokushisa okuphansi kanye nokuzwela kwenotshi ephansi.Ukuqina kwensimbi okuhle, lapho amanzi ecisha ukuba lukhuni ku-Ф 28 ~ 60 mm, lapho ukucisha uwoyela kufinyelela ku-40 mm ukucisha insimbi kuyafaneleka Ф5 mm1. i-cyanidation kanye ne-high frequency quenching.Lapho ubulukhuni buyi-174 ~ 229HB, i-machinability yesihlobo ingu-60%.Insimbi ifaneleka ukwenza isikhunta sepulasitiki esiphakathi nendawo.

Insimbi ene-carbon tempered steel, i-cold heading die steel.Insimbi inenani elimaphakathi, kulula ukuyicubungula futhi ingathola ubulukhuni obuthile, ipulasitiki kanye nokumelana nokuhuzuka ngemva kokwelashwa okufanele kokushisa.I-normalizing ingathuthukisa ukusebenza kokusika okungenalutho ngokukhuthaza ukucolisiswa kwe-microstructure futhi isondele esimweni sokulingana.I-Tempered at 550~570℃ iphakeme kunensimbi engu-45, ilungele ukucisha imvamisa ephezulu, ukucisha ilangabi nokunye ukwelashwa kokuqina kwendawo.

Izingxenye ze-shaft zingenye yezingxenye ezivamile okuvame ukuhlangana nazo emishinini.Isetshenziselwa ikakhulukazi ukusekela izingxenye zokudlulisela, ukudlulisa i-torque kanye nomthwalo.Izingxenye zeshaft ziyizitho zomzimba ezijikelezayo, ubude bazo bukhulu kunobubanzi, ngokuvamile obuhlanganiswe ne-concentric shaft cylindrical surface, i-conical surface, imbobo yangaphakathi kanye nentambo kanye nendawo yokugcina ehambisanayo. i-shaft, i-hollow shaft kanye ne-crankshaft.

I-40Cr iyinto evamile yezingxenye ze-shaft. Ishibhile futhi ingathola ukusebenza okungcono kakhulu kokusika ngemva kokucisha kanye nokushisa (noma ukujwayela), futhi ingathola izici eziphezulu eziphelele zemishini ezifana namandla nokuqina. Ngemva kokucisha, ubulukhuni bobuso bungafinyelela ku-45 ~ 52HRC.

I-40Cr isetshenziswa kabanzi ekwenziweni kwemishini. Lolu hlobo lwensimbi lunomshini omuhle. Le yinsimbi ye-carbon alloy esebenza kahle, i-40Cr ingaba lukhuni ibe yi-HRC45 ~ 52. Ngakho-ke, uma ubulukhuni bobuso budinga ukuthuthukiswa kanye nezakhiwo eziphakeme zemishini engu-40Cr kulindeleke ukuthi zisetshenziswe, indawo engaphezulu ye-high-frequency quenching, imvamisa ukucisha imvamisa ye-40 Cr kuyaye kwenziwa ngemva kokucisha ukuqina kwe-40 Cr. 55-58hrc, ukuze uthole ubulukhuni obuphezulu obudingekayo futhi ugcine ukuqina okuhle kwenhliziyo.
