Hauv kev tsim cov txheej txheem ntawm kev sib txuas ntawm cov ncej sprocket, cov txheej txheem kho cua sov yog ib kauj ruam tseem ceeb hauv kev ua kom cov khoom ua tau zoo dua. Los ntawm kev ua tib zoo xaiv cov khoom siv, kev tswj xyuas meej ntawm kev kho cua sov, kev siv cov xov xwm tshwj xeeb txias, thiab kev tshuaj xyuas zoo, Daiyue Machinery ua kom nws cov khoom muaj kev ruaj ntseg tshwj xeeb thiab lub neej ntev kev pab cuam nyob rau hauv kev ua haujlwm hnyav.
1. Kev xaiv zoo ua ib lub hauv paus ruaj khov
High- cov ntaub ntawv raw khoom zoo yog lub hauv paus ntawm cov khoom ua tau zoo -. Daiyue Machinery siv siab - zoo los yog siab heev alloy steels xws li 42CrMo thiab 40CrNiMoA rau nws sprocket ncej sib dhos Cheebtsam. Cov ntaub ntawv no muaj npe nrov rau lawv qhov tshwj xeeb hardenability, txhim kho tag nrho cov khoom ua tau zoo thiab muab kev txhawb nqa txhim khu kev qha rau cov txheej txheem kho cua sov tom ntej. Sprocket ncej sib dhos yog feem ntau siv nyob rau hauv huab ib puag ncig xws li mines thiab underground, yuav tsum tau muaj zog, toughness, thiab zoo heev hnav tsis kam.
2. quenching thiab Tempering txheej txheem: Precise Control tshaj txhua kauj ruam
quenching thiab tempering yog cov txheej txheem tseem ceeb hauv sprocket ncej sib dhos tsim, aiming kom optimize tag nrho cov neeg kho tshuab zog ntawm qhov chaw. Lub qhov cub hluav taws xob uas muaj qhov ntsuas kub ntawm qhov tseeb ntawm ± 5℃thiab kaw - lub voj voog ntsuas qhov ntsuas kub hauv tag nrho cov txheej txheem kom ntseeg tau tias qhov kub thiab txias nyob hauv qhov zoo tagnrho thaum lub sijhawm cua sov thiab tuav.
Tom qab siab -kub tempering ntxiv txhim kho qhov ua tau zoo, tsim kom muaj cov qauv sorbite. Tom qab quenching thiab tempering, sprocket ncej sib dhos qhov chaw nthuav tawm cov hauv qab no zoo:
Uniform hardness: Tsis tshua muaj hardness faib tawm ntawm qhov chaw mus rau sab hauv;
Lub zog tensile zoo heev (σb Ntau dua lossis sib npaug ntawm 940 MPa): Ua tau lossis tseem tshaj lub teb chaws tus qauv;
Zoo heev low-kub toughness (k Ntau dua los yog sib npaug rau 40J ntawm -20 degree): Qhov tseem ceeb txo qhov kev pheej hmoo ntawm kev tawg hauv av;
ductility zoo heev (δ Ntau dua lossis sib npaug li 12%): Haum rau kev ua haujlwm ntev - nyob rau hauv cov xwm txheej nyuaj.
3. Nto quenching: Txhim kho qhov chaw tseem ceeb
Ntxiv nrog rau kev txhim kho kev ua tau zoo tag nrho, Daiyue Machinery tseem them nyiaj tshwj xeeb rau kev ntxiv dag zog rau thaj chaw ntawm thaj chaw. Piv txwv li, lub tuam txhab siv nruab nrab - thiab siab - cov khoom siv zaus rau saum npoo quenching nyob rau hauv siab - coj qhov chaw xws li splines thiab saw zes. Cov txheej txheem no tau tswj hwm qhov tawv tawv ntawm 55 thiab 60 HRC, txhim kho ob qho tib si hnav tsis kam thiab qaug zog.
Cov kev paub dhau los tau pom tias qhov chaw- cov khoom tawv tawv tau dhau los ua 50% txo tus nqi hnav raws li kev cuam tshuam ntawm gangue, thaum ua tiav kev ua haujlwm qaug zog ntawm ntau dua 10,000 teev nyob rau hauv cov khoom sib hloov, ntau dua peb npaug ntawm cov qauv kev lag luam.
