Kev daws ntawm Pob Zeb Slabs Khoov
Nws yog feem ntau ntseeg tias lub ntsiab ua rau pob zeb txiav puas yog qhov zoo ntawm cov saw hniav (cov khoom tiav) thiab qhov zoo ntawm cov saw hniav siv tshuab. Kev tsim thiab ua tiav ntawm cov txheej txheem sawing hauv cov neeg siv khoom yog ncaj qha ntsig txog. Tsis tas li ntawd, nws muaj feem xyuam rau tag nrho qhov zoo ntawm lub tshuab sawing. Kev txhim kho thiab kev saib xyuas ntawm lub tshuab sawing, nrog rau kev txias thiab lubrication ntawm cov txheej txheem txiav.
1. Qhov tseem ceeb tshaj plaws kev daws teeb meem rau saw hniav core thiab slab dabtsi yog khoov
Raws li ib txwm muaj, cov saw hlau tshiab yuav tswj cov nqi nro, flatness thiab kawg runout ua ntej tawm hauv lub Hoobkas. Txawm li cas los xij, thaum qee cov cores siv nyob rau hauv pob zeb factories, deviations feem ntau tshwm sim, uas ua rau txo qis tus nqi tsim nyog ntawm slab txiav. Lub ntsiab manifestations yog: cov txheej txheem txheej txheem saws los ntawm cov pob zeb ua cov nroj tsuag tsis phim tus nqi nro tseem ceeb. Thaum tus nqi zoo nro loj heev, nws yog ib qho yooj yim ua rau nce thiab nqis dabtsi yog khoov. Qee cov hlau cores tau mus txog qhov kawg ntawm lawv lub neej kev pabcuam tom qab rov ua dua, thiab qhov tshwm sim no tuaj yeem tshwm sim. Yog li ntawd, thaum xaiv cores, pob zeb ua cov chaw tsim khoom yuav tsum tsis txhob khav theeb rau pheej yig, thiab xaiv cov cores tsis tsim nyog. Txawm li cas los xij, cov hlau zoo zoo uas tsim los ntawm cov tuam txhab tsim nyog yuav tsum raug xaiv. Nyob rau tib lub sijhawm, xyuam xim rau lub neej voj voog ntawm rov vuam cov hniav kom txo tau qhov tsis tsim nyog.
2. Pob zeb diamond ntu
Kev txiav thiab khoov ntawm cov slab feem ntau yog vim lub pob zeb diamond saw hniav tsis ntse. Nyob rau hauv cov ntaub ntawv ntawm overloading, cov hniav yog stressed los yog overloaded, uas ua rau ntau tshaj txiav tam sim no thiab dabtsi yog khoov ntawm slab. Yog li ntawd, ua ntej txiav, lub pob zeb ua cov nroj tsuag yuav tsum chisel thiab sharpen lub tshiab pob zeb diamond ntu. Yog tias tsim nyog, kev siv tshuab gouging tuaj yeem siv los txo qhov sib txawv ntawm qhov kev khiav tawm thiab qhov kawg dhia. Txawm li cas los xij, qee lub pob zeb ua cov nroj tsuag nyob rau hauv cov xwm txheej tsis zoo thiab tsis tuaj yeem siv cov tshuab chiseling. Tab sis siv random chiseling. Nyob rau hauv cov txheej txheem ntawm kev khawb hauv av, nruj txiav thiab txiav cov txheej txheem yuav tsum tau tsim, thiab ua tiav ntawm 1/3 lossis 1/4 ntawm qhov qub txiav lossis taug kev ceev. Thiab lub" hniav" yuav tsum tau siab" ntse" kom txo tau cov hniav radial runout yuam kev. Txwv tsis pub, nyob rau hauv tus txheej txheem ntawm kev txiav los yog tshaj-load txiav, cov saw hniav tseem ceeb tsis tuaj yeem tiv taus qhov loj loj. Nws yuav ua rau deterioration ntawm flatness, nro tus nqi, thiab kawg-lub ntsej muag runout.
3. Ua haujlwm zoo ntawm sawing tshuab
Raws li kev tshawb nrhiav, kab rov tav kev taw qhia ntawm cov saw yog hnav tawm tom qab siv lub sijhawm, thiab qhov raug txo qis. Kev tswj kom zoo tsis ua raws li tus qauv. Thaum crawling tshwm sim, lub slab yog nquag khoov sab laug thiab sab xis. Thaum pom' s longitudinal (verttical) lifting civil rail ib feem yog hnav. Thaum qhov raug txo qis thiab qhov raug tsis ncav cuag, lub slab yog nquag buckling. Nyob rau tib lub sijhawm, thaum qhov sib txawv ntawm qhov sib txawv ntawm cov saw hniav qhia tau raug kho tsis raug lossis cov khoom txawv teb chaws nkag mus rau hauv phau ntawv qhia. Yooj yim rau khoov. Tsis tas li ntawd, kev ua haujlwm tsis zoo ntawm lub tshuab sawing spindle kuj yog ib qho tseem ceeb ua rau slab dabtsi yog khoov. Yog li ntawd, qhov tseeb ntawm cov saw tseem ceeb tsav ncej thiab qhov tsim nyog hloov ntawm spindle bearing clearance kuj tseem ceeb heev. Txwv tsis pub, irregular slab dabtsi yog khoov yuav tshwm sim.
4. Kev txhim kho thiab tu cov saws thaum siv
Tsis tas li ntawd, kev saib xyuas ib txwm ntawm cov saw hniav thaum siv thiab tshem tawm cov khoom txawv teb chaws raws sij hawm ntawm cov lus qhia rail. Thaum hloov cov saw hniav, qhov tseeb ntawm cov saw hniav flange yog nruj tshwj xeeb. nruj me ntsis xyuas cov flange flatness thiab kawg lub ntsej muag runout ua ntej hloov, thiab tshem tawm burrs thiab txawv teb chaws khoom. Yog tias qhov sib txawv tsis ua raws li qhov yuav tsum tau ua, nws yuav tsum tau kho lossis hloov.
Nyob rau tib lub sijhawm, kuv lub laub khiav zoo. Nws yog ib qho tseem ceeb heev los txhim kho lub mine lub laub ntawm lub laub thiab xyuas nws nquag thaum lub sijhawm tsim khoom. Nws tseem yog ib qho tseem ceeb los xyuas kom meej qhov ncaj thiab tsis muaj cov khoom txawv teb chaws hauv kev khiav ntawm lub trolley.
5. Txias thiab lubrication ntawm sawing tshuab thaum txiav
Txhawm rau kom ntseeg tau qhov kev txiav ib txwm ntawm cov saw hniav, txuas ntxiv nws lub neej kev pabcuam, thiab txhim kho qhov zoo ntawm lub rooj tsavxwm thaum siv cov saw. Feem ntau npaj ib lub pob zeb tshwj xeeb txiav coolant. Thiab tswj kom ruaj khov txias thiab lubrication zoo thaum lub sijhawm tsim khoom, thiab qhov txaus txaus thiab sib npaug ntawm cov saw hniav tseem ceeb. Qee cov neeg siv tsis siv lub tshuab ua kom txias, tab sis siv cov dej kais dej rau kev txiav thiab txias, uas txo cov naj npawb ntawm rewelding thiab lub neej kev pab cuam ntawm cov tub ntxhais, uas cuam tshuam rau qhov zoo ntawm cov slab. Yog li ntawd, kev ua kom txias thiab lubrication zoo tuaj yeem ua kom tiav thiab ua haujlwm tau zoo ntawm cov saw hniav, txo cov nqi txiav, thiab tiv thaiv qhov tshwm sim ntawm slab dabtsi yog khoov.
