imathiriyeli 40cr

I-40Cr yinombolo yentsimbi ye-GB esemgangathweni e-China, kunye ne-40Cr yentsimbi yenye yezona zinto zisetyenziswa kakhulu kwi-industry yemveliso yomatshini. Ineempawu ezilungileyo ezibanzi zomatshini, ukuqina okuhle kobushushu obuphantsi kunye ne-notch ephantsi sensitivity.Ukuqina kwentsimbi, xa amanzi ecima ukuqina ukuya ku-Ф 28 ~ 60 mm, xa ukucima i-oyile kukucima i-40 mm Ф5 mm . i-cyanidation kunye ne-high frequency quenching.Xa ubulukhuni bu-174 ~ 229HB, i-machinability yesihlobo yi-60%.Intsimbi ifanelekile ukwenza iimbumba zeplastiki ezinobungakanani obuphakathi.

Medium carbon tempered steel, i-cold heading die steel.Intsimbi yexabiso eliphakathi, kulula ukuyiqhuba kwaye inokufumana ubunzima obuthile, iplastiki kunye nokuxhathisa i-abrasion emva kokulungiswa kobushushu obufanelekileyo.I-normalizing inokuphucula ukusebenza kokusika kwe-blank ngokukhuthaza ukucocwa kwe-microstructure kunye nokusondela kwi-equilibrium state.I-Tempered kwi-550 ~ 570 ℃ i-steel compreability, i-steel comprebility, i-steel comprebility, i-hehen, i-mechanical comprency, i-steel comprebility, iphezulu kunentsimbi ye-45, ilungele ukucinywa kwamaxesha amaninzi, ukucima amadangatye kunye nolunye unyango lokuqina komphezulu.

Inxalenye ye-shaft yenye yeendawo eziqhelekileyo ezihlala zidibana nazo kumatshini.Isetyenziselwa kakhulu ukuxhasa amacandelo othumelo, i-torque yokudlulisa kunye nomthwalo.Amalungu e-shaft ajikeleza amalungu omzimba, ubude bawo bukhulu kunobubanzi, ngokuqhelekileyo buqulunqwe ngumgangatho odibeneyo we-shaft cylindrical surface, i-conical surface, umngxuma wangaphakathi kunye nentambo kunye nomphezulu ohambelanayo wesiphelo ishaft, i-hollow shaft kunye ne-crankshaft.

I-40Cr yinto eqhelekileyo yeengxenye ze-shaft. Ixabiso eliphantsi kwaye linokufumana umsebenzi ongcono wokusika emva kokucima kunye nokucaphuka (okanye ukulinganisa), kwaye unokufumana iipropathi eziphezulu ezibanzi zoomatshini ezifana namandla kunye nokuqina. Emva kokucima, ukuqina komphezulu kunokufikelela kwi-45 ~ 52HRC.

I-40Cr isetyenziswa ngokubanzi kwimveliso yomatshini. Olu hlobo lwentsimbi luneempawu ezintle zoomatshini. Le yintsimbi ye-carbon alloy ephakathi kunye nokusebenza kakuhle kokucima, i-40Cr inokuqiniswa ukuya kwi-HRC45 ~ 52. Ngoko ke, ukuba ubunzima bomhlaba bufuna ukuphuculwa kunye neempawu eziphezulu zemishini ye-40Cr zilindeleke ukuba zifakwe ekudlaleni, umgangatho ophezulu we-high-frequency quenching i-40 Cr isoloko iqhutywe emva kokunyanzeliswa kwe-40 Cr. 55-58hrc, ukuze ufumane ubulukhuni bomphezulu obufunekayo kwaye ugcine ukuqina okuhle kwentliziyo.
