Qhov cuam tshuam ntawm qhov kub thiab txias rau kev ua haujlwm ntawm Isothermal Roller Chain Plates: Cov Qauv Zoo Tseem Ceeb uas Txhua Tus Neeg Yuav Khoom Yuav Tsum Paub
Hauv kev lag luam kis tau tus mob industrial,cov saw hlauKev ua tau zoo ncaj qha txiav txim siab qhov ua haujlwm zoo thiab lub neej ua haujlwm ntawm cov khoom siv. Raws li lub hauv paus, cov khoom siv thauj khoom ntawm cov saw hlau, qhov zoo ntawm lub phaj saw hlau isothermal yog qhov tseem ceeb tshaj plaws. Kev ua tau zoo ntawm lub phaj saw hlau muaj feem cuam tshuam nrog cov txheej txheem kho cua sov, nrog rau qhov kub thiab txias, qhov tseem ceeb, muaj kev cuam tshuam rau cov cim tseem ceeb xws li qhov nyuaj ntawm cov saw hlau, kev tawv, thiab kev tiv thaiv kev hnav.
1. Kev Sib Raug Zoo Ntawm Cov Phaj Isothermal Chain Thiab Cov Txheej Txheem Tempering
Cov phaj saw hlau isothermal yog cov khoom tseem ceeb uas tsim los ntawm cov txheej txheem austempering, uas muab qee qib ntawm kev tawv thaum tseem tswj tau lub zog. Tempering, kauj ruam kawg hauv kev kho cua sov, feem ntau tshem tawm cov kev ntxhov siab sab hauv tom qab quenching, kho cov qauv sab hauv ntawm cov hlau, thiab thaum kawg txiav txim siab cov khoom siv kho tshuab ntawm cov saw hlau.
Thaum lub sijhawm ua kom sov, txawm tias qhov kub me me xwb los kuj ua rau muaj kev hloov pauv ntawm cov qauv hlau sab hauv ntawm lub phaj saw hlau. Thaum qhov kub ntawm kev ua kom sov qis dhau, feem ntau ntawm cov qauv martensite uas tsim thaum lub sijhawm quenching tseem nyob. Txawm hais tias qhov no tswj tau qhov nyuaj siab, kev ntxhov siab sab hauv tsis tau tso tawm tag nrho, ua rau cov saw hlau tawg yooj yim dua. Yog tias qhov kub siab dhau, cov martensite yuav lwj ntau dhau, ua rau cov saw hlau lub zog thiab qhov nyuaj txo qis, ua rau nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Yog li ntawd, kev tswj hwm qhov kub ntawm kev ua kom sov yog ib qho thev naus laus zis tseem ceeb rau kev sib npaug ntawm cov yam ntxwv ntawm ntau yam kev ua tau zoo ntawm cov saw hlau.
2. Qhov Cuam Tshuam ntawm Qhov Kub thiab Txias rau Qhov Nyuaj ntawm Cov Hlau: Kev Sib Npaug Lub Zog thiab Kev Siv Tau Zoo
Qhov tawv yog qhov qhia tau tias lub saw hlau muaj peev xwm nqa tau lub nra hnyav thiab muaj feem cuam tshuam ncaj qha rau lub peev xwm ntawm cov saw hlau kom tiv taus kev hloov pauv thaum muaj kev thauj khoom ntau. Cov ntaub ntawv sim qhia tau tias muaj kev sib raug zoo tsis zoo ntawm qhov kub thiab txias thiab qhov tawv ntawm cov saw hlau.
Thaum qhov kub ntawm tempering yog nruab nrab ntawm 200 ° C thiab 300 ° C, qhov nyuaj ntawm cov saw hlau tuaj yeem tswj tau ntawm 38 thiab 42 HRC, uas yog qhov ntau uas ua tau raws li qhov yuav tsum tau ua ntawm feem ntau ntawm cov ntawv thov kis tau tus mob hauv kev lag luam. Ntawm qhov kub no, cov carbide me me hauv cov saw hlau zoo thiab faib sib npaug, khaws cia lub zog siab uas tau txais tom qab quenching thaum tseem tshem tawm qee qhov kev ntxhov siab sab hauv los ntawm kev tempering qis. Yog tias qhov kub nce mus txog 350-450 ° C, qhov nyuaj poob rau 30-35 HRC. Thaum lub zog txo qis, qhov tawv tawv txhim kho ntau heev, ua rau nws tsim nyog rau cov khoom siv uas xav tau kev pib ntau zaus. Txawm li cas los xij, thaum qhov kub tshaj 500 ° C, qhov nyuaj poob qis dua 25 HRC, thiab lub phaj saw hlau yooj yim rau kev hloov pauv yas, ua rau nws tsim nyog rau cov xwm txheej kis tau yooj yim nrog cov khoom thauj me me thiab qhov ceev qis.
Cov neeg yuav khoom yuav tsum xaiv cov phaj saw hlau uas muaj qhov kub thiab txias uas tsim nyog rau qhov ntsuas ntawm lawv cov khoom siv. Piv txwv li, cov saw hlau rau cov tshuab khawb av, uas yuav tsum tiv taus qhov cuam tshuam loj heev, yuav tsum tau tempered ntawm kwv yees li 250 ° C rau cov saw hlau uas muaj zog heev. Cov saw hlau tsav rau cov kab ua zaub mov, ntawm qhov tod tes, tuaj yeem tempered ntawm 350 ° C rau cov saw hlau uas muaj zog nruab nrab, sib npaug ntawm kev tawv thiab kev tiv taus hnav.
3. Kev Tawm Tsam thiab Kev Qaug Zog: Qhov Cuam Tshuam Zais Cia ntawm Qhov Kub Tempering
Qhov tawv ntawm lub phaj saw hlau txiav txim siab nws qhov kev tiv thaiv kev cuam tshuam, thaum qhov kev tiv thaiv kev qaug zog txiav txim siab lub neej ntawm lub saw hlau. Txawm hais tias nyuaj rau ntsuas ncaj qha, ob qho cim no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntev ntawm cov khoom siv thiab ob qho tib si cuam tshuam los ntawm qhov tob ntawm qhov kub tempering. Kev tempering kub qis (qis dua 200 ° C) ua rau muaj kev ntxhov siab ntau hauv lub phaj saw hlau, ua rau tsis muaj kev tawv thiab yooj yim tawg thaum muaj kev cuam tshuam ntau zaus. Thaum qhov kub tempering nce mus txog 300-400 ° C, qhov kev ntxhov siab seem maj mam tso tawm, qhov tawv ntawm ferrite matrix rov qab los, thiab lub phaj saw hlau qhov kev tiv thaiv kev cuam tshuam tuaj yeem nce ntxiv ntau dua 30%. Ntawm qhov kub no, lub phaj saw hlau yuav tsis tawg thaum muaj kev thauj khoom tsis tu ncua, ua rau nws tsim nyog rau cov tshuab nrog kev pib thiab nres ntau zaus, xws li cov khoom siv stamping thiab cranes.
Qhov kev tiv thaiv kev qaug zog ncav cuag nws qhov siab tshaj plaws thaum tempered ntawm 400-450 ° C. Qhov kub thiab txias no txhawb nqa cov carbide precipitation sib npaug, tsim cov qauv bainite tempered ruaj khov uas tiv thaiv kev pib thiab kev nthuav dav ntawm qhov tawg qaug zog. Kev sim tau qhia tias cov saw hlau tempered ntawm 420 ° C tuaj yeem ntev lawv lub neej qaug zog los ntawm 2-3 zaug piv rau cov khoom zoo sib xws tempered ntawm 200 ° C.
Rau cov khoom siv uas ua haujlwm tas mus li rau lub sijhawm ntev, xws li cov khoom siv thauj khoom thiab cov tshuab ua ntawv, kev xaiv cov phaj saw hlau uas tau tempered ntawm ib ncig ntawm 400 ° C tuaj yeem txo qhov zaus txij nkawm. Hauv cov xwm txheej uas muaj cov khoom cuam tshuam tsawg dua, kev nce qhov kub tempering kom tsim nyog kom ua tiav lub neej qaug zog ntev dua tuaj yeem txo cov nqi khiav lag luam tag nrho.
4. Kev Tiv Thaiv Kev Hnav Thiab Kev Tiv Thaiv Kev Xeb: Tus Nqi Ntxiv ntawm Kev Kub Ntxhov
Ntxiv rau cov khoom siv kho tshuab, qhov hnav thiab kev tiv thaiv corrosion ntawm cov saw hlau kuj raug cuam tshuam los ntawm qhov kub thiab txias, uas yog qhov tseem ceeb tshwj xeeb hauv qab kev ua haujlwm hnyav.
Thaum lub sijhawm kub txog 300-400 ° C, cov zaj duab xis oxide uas tsim rau ntawm qhov saw hlau muaj cov qauv ntom ntom, muab qee qhov kev tiv thaiv tiv thaiv kev hnav los ntawm cov khoom tsis huv hauv cov roj lubricating. Ntxiv mus, cov saw hlau kho hauv qhov kub no muaj qhov nyuaj ntawm qhov chaw nruab nrab, txo qhov hnav ntawm cov menyuam thiab cov koob, thiab txo cov hlau khib nyiab thaum lub sijhawm kis.
Nyob rau hauv cov chaw noo noo lossis corrosive, cov saw hlau uas tau tempered saum 450 ° C ua haujlwm zoo dua. Qhov kub siab dua tempering txo cov pa roj carbon ntawm cov saw hlau, txo qhov yuav muaj kev xeb intergranular, thaum tseem txhawb kev tsim cov zaj duab xis passive thiab txhim kho kev tiv thaiv xeb. Piv txwv li, hauv cov khoom siv ua dej, cov saw hlau uas tau tempered ntawm 500 ° C muaj lub neej xeb 1.5 npaug ntawm cov saw hlau uas tau tempered ntawm 300 ° C.
Thaum xaiv cov saw hlau, cov neeg yuav khoom yuav tsum xav txog qhov chaw ua haujlwm kom meej. Hauv cov chaw khawb av uas muaj plua plav, cov saw hlau uas tiv taus kev hnav thiab kub txog 350°C yog qhov zoo dua. Hauv cov tshuab ua liaj ua teb uas muaj av noo, cov saw hlau uas tiv taus xeb yuav tsum kub txog 450°C lossis siab dua.
5. Phau Ntawv Qhia Txog Kev Txiav Txim Siab Yuav Khoom: Yuav Ua Li Cas Xaiv Saw Raws Li Qhov Kub Tempering
Raws li qhov cuam tshuam ntawm qhov kub thiab txias rau kev ua haujlwm ntawm cov saw hlau, cov neeg yuav khoom tuaj yeem ua qhov kev xaiv kom raug los ntawm kev ua raws li cov kauj ruam hauv qab no:
Ua ntej, txiav txim siab seb cov khoom siv yuav tsum tau ua dab tsi. Yog tias lub zog ntawm lub nra yog qhov tseem ceeb, xws li hauv cov tshuab hlau, xaiv cov saw hlau uas tau tempered ntawm 250-300 ° C. Yog tias qhov kev tiv thaiv kev qaug zog yog qhov tseem ceeb, xws li hauv cov tshuab textile, muab qhov tseem ceeb rau cov khoom uas tau tempered ntawm 400-450 ° C.
Qhov thib ob, soj ntsuam qhov chaw ua haujlwm. Hauv qhov chaw ua haujlwm qhuav thiab huv si, tsom mus rau qhov nyuaj. Hauv qhov chaw noo noo thiab plua plav, xav txog ob qho tib si kev tiv thaiv kev hnav thiab kev tiv thaiv corrosion, thiab nce qhov kub tempering kom haum.
Thaum kawg, xyuas kom meej tias tus neeg muag khoom muaj peev xwm tswj cov txheej txheem. Cov neeg muag khoom zoo yuav muab cov ntsiab lus qhia txog qhov kub thiab txias thiab cov ntawv qhia kev ua tau zoo kom ntseeg tau tias muaj kev ua tau zoo sib xws thoob plaws txhua pawg ntawm cov phaj saw. Nws raug pom zoo kom xaiv lub chaw tsim khoom uas tuaj yeem tswj tau qhov kub thiab txias tsis pub dhau ± 10 ° C kom tsis txhob muaj kev pheej hmoo zoo los ntawm kev hloov pauv ntawm cov txheej txheem.
