Cov saw hlau yog cov khoom siv uas muaj nyob rau ntau yam lag luam, txij li cov khoom siv tsim khoom mus rau tsheb kauj vab thiab maus taus. Txawm hais tias lawv qhov tseem ceeb tsis tuaj yeem hais ntau dhau, ntau tus neeg tseem tsis paub txog cov txheej txheem nyuaj uas koom nrog kev tsim cov txheej txheem tseem ceeb no. Hauv tsab blog no, peb nkag mus rau hauv lub ntiaj teb zoo kawg nkaus ntawm kev tsim cov saw hlau, tshawb nrhiav cov kauj ruam ua tib zoo uas koom nrog kev hloov cov khoom siv raw mus rau hauv cov saw hlau raug.
1. Kev xaiv cov khoom siv raw:
Cov txheej txheem pib nrog kev xaiv cov hlau zoo lossis hlau tsis xeb ua cov khoom siv tseem ceeb. Cov ntaub ntawv no tau raug xaiv rau lawv lub zog tensile siab, ruaj khov thiab tiv taus corrosion - cov yam tseem ceeb thaum ua haujlwm sab nraum zoov.
2. Kos duab:
Cov hlau lossis cov hlau tsis xeb uas tau xaiv yuav raug kos los ntawm cov hlau xaim, uas yog ib qho txheej txheem uas kos cov khoom siv los ntawm ntau lub pwm kom txo nws txoj kab uas hla thaum ua kom nws ntev dua. Qhov no tsim cov hlau xaim uas ruaj khov thiab yooj yim khoov tau uas tom qab ntawd yuav dhau los ua lub hauv paus ntawm kev tsim cov saw hlau.
3. Kev sib tsoo txias:
Tom ntej no, cov hlau raug forged txias kom ua ib lub voj voog, khov kho uas sawv cev rau lub hauv paus ntawm cov saw hlau. Cov txheej txheem forging txias ua kom ntseeg tau tias cov pins muaj qhov nyuaj thiab tsim qauv tsim nyog rau kev ua haujlwm zoo tshaj plaws hauv qab cov khoom hnyav thiab qhov chaw nyuaj.
4. Kev tsim cov nruas:
Tib lub sijhawm, cov hlau cylindrical rods raug txiav kom raug qhov ntev thiab tom qab ntawd milled los ua cov rollers. Cov nto milled raug zom kom zoo kom ntseeg tau tias kev ua haujlwm du thiab txo qis kev sib txhuam, ua rau kev ua haujlwm zoo dua thiab lub neej ua haujlwm ntawm cov saw hlau roller nce ntxiv.
5. Kev luam ntawv ntawm cov vaj huam sib luag sab:
Cov phaj sab uas muaj cov koob thiab cov menyuam ces ua los ntawm cov hlau tsis muaj zog. Cov phaj no tau tsim kom meej kom muaj cov qhov thiab qhov chaw tsim nyog los pab cov koob thiab txuas cov saw hlau ua ke.
6. Sib dhos:
Thaum cov khoom sib dhos tiav lawm, cov txheej txheem sib dhos pib. Muab cov pins tso rau hauv cov qhov sib xws ntawm ib sab phaj, tom qab ntawd ntxiv cov rollers uas tau teeb tsa kom raug. Tom qab ntawd sab nraud vaj huam sib luag raug teeb tsa thiab nias rau hauv qhov chaw kom ua tiav cov saw hlau sib txuas.
7. Kev kho cua sov:
Yuav kom cov saw hlau muaj zog thiab siv tau ntev, cov saw hlau uas sib dhos ua ke tag nrho yuav raug kho cua sov. Cov txheej txheem no yuav tsum ua kom cov saw hlau kub heev, tom qab ntawd txias sai sai. Kev kho cua sov ua rau cov saw hlau tsis yooj yim hnav, tsis yooj yim qaug zog, thiab ruaj khov.
8. Kev kho qhov chaw:
Nyob ntawm seb yuav tsum tau siv li cas, cov saw hlau yuav raug kho kom zoo dua ntxiv. Cov kev kho no, xws li kev pleev xim nickel lossis kev ua kom dub, tuaj yeem muab kev tiv thaiv ntxiv tiv thaiv kev xeb lossis txhim kho qhov zoo nkauj ntawm cov saw hlau.
9. Kev tswj xyuas zoo:
Ua ntej cov saw hlau raug ntim thiab npaj rau kev faib tawm, lawv yuav tsum tau ua raws li kev tswj xyuas zoo. Cov kev ntsuam xyuas no suav nrog kev kuaj xyuas qhov tseeb ntawm qhov ntev, kev sim thauj khoom puas tsuaj, thiab kev tshuaj xyuas seb puas muaj qhov tsis zoo ntawm qhov chaw. Cov txheej txheem tswj xyuas zoo no ua kom ntseeg tau tias tsuas yog cov saw hlau zoo tshaj plaws thiaj li nkag mus rau hauv kev ua lag luam.
Cov txheej txheem tsim cov saw hlau yog kev sib xyaw ua ke ntawm kev tsim kho kom raug, cov thev naus laus zis tshiab thiab kev ua haujlwm txawj. Txij li thaum xaiv cov khoom siv raw mus rau qhov kev tshuaj xyuas zoo kawg, txhua kauj ruam ua lub luag haujlwm tseem ceeb hauv kev tsim cov saw hlau txhim khu kev qha thiab ua haujlwm tau zoo.
Txawm peb paub los tsis paub, cov saw hlau ua rau muaj kev txav mus los tsis muaj kev cuam tshuam ntawm ntau lub tshuab, cav thiab tsheb. Kev paub txog cov txheej txheem tsim khoom nyuaj tom qab cov txuj ci tseem ceeb no tau muab kev nkag siab tshiab rau peb txog cov txuj ci tseem ceeb ntawm kev tsim kho uas ua rau muaj zog thiab muaj zog rau cov lag luam uas peb vam khom.
