impahla 40cr

I-40Cr inombolo yensimbi evamile ye-GB e-China, futhi insimbi engu-40Cr ingenye yensimbi esetshenziswa kakhulu embonini yokukhiqiza imishini.Inezici ezinhle zemishini ezibanzi, ukuqina okuhle komthelela ophansi wokushisa nokuzwela okuphansi.Ukuqina kwensimbi okuhle, lapho amanzi ecisha. ukuqina ku-Ф 28 ~ 60 mm, lapho uwoyela ucisha ukuqina ku-Ф 15 ~ 40 mm. Insimbi ibuye ifanele i-cyanidation kanye nokucisha imvamisa ephezulu.Lapho ubulukhuni buyi-174 ~ 229HB, i-machinability yesihlobo i-60%.Insimbi ifanelekile ukwenza isikhunta sepulasitiki esiphakathi nendawo.

Insimbi ene-carbon tempered steel, i-cold heading die steel.Insimbi inenani elilinganiselwe, kulula ukuyicubungula futhi ingathola ukuqina okuthile, ukuqina kwepulasitiki kanye nokumelana nemihuzuko ngemva kokwelashwa okufanele kokushisa.Ukwejwayelekile kungathuthukisa ukusebenza kokusika kokungenalutho ngokukhuthaza ukucolisiswa kwe-microstructure kanye isondela kusimo sokulinganisa.Ifakwe ku-550 ~ 570 ℃, insimbi inezindawo ezinhle kakhulu zemishini ebanzi.Ukuqina kwensimbi kuphakeme kunensimbi engu-45, ifanele ukucisha imvamisa ephezulu, ukucisha ilangabi nokunye ukwelashwa kokuqina kwendawo.

Izingxenye zeshaft zingenye yezingxenye ezivame ukuhlangana nazo emishinini. Isetshenziselwa kakhulu ukusekela izingxenye zokudlulisela, ukudlulisa i-torque kanye nomthwalo. Izingxenye zeshaft ziyizitho zomzimba ezizungezayo, ubude bazo bukhulu kunobubanzi, ngokuvamile obuhlanganiswe ne-concentric shaft cylindrical. indawo engaphezulu, i-conical surface, imbobo yangaphakathi kanye nentambo kanye nendawo yokugcina ehambisanayo.Ngokuvumelana nokuma okuhlukene kwesakhiwo, izingxenye ze-shaft zingahlukaniswa zibe shaft optical, shaft shaft, shaft engenalutho 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 zomshini eziphelele eziphelele njengamandla nokuqina.Ngemva kokucisha, ubulukhuni bobuso bungafinyelela ku-45 ~ 52HRC.

I-40Cr isetshenziswa kabanzi ekwenziweni kwemishini.Lolu hlobo lwensimbi lunezinto ezinhle zomshini.Lena insimbi ye-carbon alloy ephakathi nokusebenza kahle kokucisha, i-40Cr ingaba lukhuni ibe yi-HRC45~52.Ngakho-ke, uma ubulukhuni bobuso budinga ukuthuthukiswa kanye nezakhiwo ezisezingeni eliphezulu zemishini engu-40Cr kulindeleke ukuthi Uma kufanele udlalwe, ukwelashwa kokucisha imvamisa ephezulu kuvame ukwenziwa ngemuva kokumiswa kwe-40Cr, ngobulukhuni obufika ku-55-58hrc, ukuze kutholwe ubulukhuni obuphezulu obudingekayo nokugcina ukuqina okuhle kwenhliziyo.
