Raws li lub npe qhia, ntau cov hniav saws yog pom cov hniav uas tau nruab thiab siv ua ke. Feem ntau, alloy saw hniav yog cov tseem ceeb.

Ntau cov hniav saws feem ntau yog siv rau kev ua ntoo, xws li: fir, poplar, ntoo thuv, eucalyptus, cov ntoo tuaj txawv teb chaws thiab lwm yam ntoo, thiab lwm yam. lwm yam kev lag luam. Yooj yim Feem ntau cov hniav tuaj yeem siv 4-6 saws, thiab sab sauv thiab sab qis tuaj yeem siv 8 saws hniav, thiab tuaj yeem nruab nrog ntau tshaj 40 saw hniav, uas zoo heev txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm. Multi-blade saw hniav yog nruab nrog ib tug xov tooj ntawm tshav kub dissipation qhov thiab expansion grooves, los yog ntau scrapers yog tsim los kom ua tau zoo dua tshav kub dissipation thiab smoother nti tshem tawm.

1. Sab nraud txoj kab uas hla ntawm ntau cov hniav saws

Nws tsuas yog nyob ntawm qhov txwv kev teeb tsa ntawm lub tshuab thiab lub thickness ntawm cov khoom txiav. Txoj kab uas hla me me yog 110MM, thiab txoj kab uas hla loj tuaj yeem ncav cuag 450 lossis loj dua. Qee cov saw hniav yuav tsum tau muab ntsia rau hauv tib lub sijhawm, lossis sab laug thiab sab xis raws li qhov yuav tsum tau ua ntawm lub tshuab, thiaj li tsis ua kom qhov loj me. Txoj kab uas hla ntawm cov saw hniav tuaj yeem ua tiav ntau dua txiav tuab thaum txo tus nqi ntawm cov saw hniav.

2. Tus naj npawb ntawm cov hniav ntawm ntau cov hniav pom hniav

Txhawm rau txo qhov tsis kam ntawm lub tshuab, ua kom lub zog ntawm cov saw hniav, thiab txo cov suab nrov, ntau cov hniav saw hniav feem ntau tsim nrog cov hniav tsawg dua. Sab nraud txoj kab uas hla ntawm 110-180 yog hais txog 12-30 hniav, thiab cov saum toj no 200 feem ntau tsuas yog Muaj txog 30-40 tus hniav. Muaj tseeb cov cav tov nrog lub zog siab dua, los yog cov tuam txhab lag luam uas hais txog cov txiaj ntsig txiav, thiab cov qauv me me yog nyob ib ncig ntawm 50 cov hniav.

3. Thickness ntawm ntau cov hniav saws

Lub thickness ntawm saw hniav: Hauv txoj kev xav, peb cia siab tias cov saw hniav yuav tsum nyias li sai tau. Lub saw kerf yeej yog ib hom kev noj. Cov khoom siv ntawm cov hlau saw hniav hauv paus thiab cov txheej txheem ntawm kev tsim cov saw hniav txiav txim siab qhov tuab ntawm cov saw hniav. Yog hais tias lub thickness yog nyias heev, lub sawb yuav yooj yim co thaum lub sij hawm ua hauj lwm, cuam tshuam rau cov nyhuv txiav. Lub thickness ntawm sab nraud txoj kab uas hla ntawm 110-150MM tuaj yeem ncav cuag 1.2-1.4MM, thiab lub thickness ntawm cov saw hniav nrog txheej txoj kab uas hla ntawm 205-230MM yog hais txog 1.6-1.8MM, uas tsuas yog haum rau txiav softwood nrog tsawg ntom. Thaum xaiv qhov tuab ntawm cov saw hniav, koj yuav tsum xav txog qhov ruaj khov ntawm cov saw hniav thiab cov khoom raug txiav. Tam sim no, txhawm rau txo kev noj haus, qee lub tuam txhab tau pib tsim ntau cov hniav saws nrog ib leeg-sab convex daim hlau lossis ob sab convex daim hlau, uas yog, ob sab ntawm lub qhov nruab nrab yog tuab dua thiab cov hlau sab hauv yog thinner. , thiab tom qab ntawd cov hniav yog welded los xyuas kom meej cov thickness. Nyob rau tib lub sijhawm, cov nyhuv ntawm cov khoom txuag tau tiav.

4. Aperture txoj kab uas hla ntawm ntau cov hniav saws

Ntawm chav kawm, lub aperture ntawm ib tug ntau-hluav taws xob saw hniav nyob ntawm seb cov yuav tsum tau ntawm lub tshuab. Vim tias ntau cov hniav raug ntsia ua ke, txhawm rau kom muaj kev ruaj ntseg, lub aperture feem ntau yog tsim los kom loj dua qhov aperture ntawm cov pa saw hniav. Feem ntau ntawm lawv nce lub aperture thiab teeb tsa txoj kev tshwj xeeb tib lub sijhawm. Lub phaj xiav yog tsim los nrog txoj hauv kev tseem ceeb los pab txhawb kev sib ntxiv ntawm cov dej txias kom txias thiab ua kom muaj kev ruaj ntseg. Feem ntau, lub aperture ntawm 110-200MM sab nraud txoj kab uas hla pom hniav yog nyob nruab nrab ntawm 3540, lub aperture ntawm 230300MM txheej txoj kab uas hla pom hniav yog nyob nruab nrab ntawm 40-70, thiab lub aperture ntawm saw hniav saum toj no 300MM yog feem ntau qis dua 50MM.

5. Cov hniav zoo li ntau cov hniav saws

Cov hniav zoo nkauj ntawm ntau cov hniav saws feem ntau yog cov hniav ntawm sab laug thiab sab xis, thiab ob peb cov hniav me me kuj tau tsim nrog cov hniav tiaj tus.

6. Txheej ntawm ntau cov hniav pom hniav

Tom qab vuam thiab sib tsoo ntawm ntau cov hniav saws tiav, lawv feem ntau yog coated, uas yog hais kom txuas ntxiv lub neej kev pab cuam. Nyob rau hauv qhov tseeb, nws yog tsuas yog rau qhov zoo nkauj tsos ntawm cov saw hniav, tshwj xeeb tshaj yog cov multi-blade saw hniav nrog ib tug scraper. Tam sim no vuam theem, scraper Muaj cov cim welding pom tseeb nyob txhua qhov chaw, yog li nws yog coated los khaws cov tsos.

7. Multi-blade saw hniav nrog scraper

Multi-blade saw hniav yog welded nrog carbide ntawm lub saw hniav puag, sib sau ua ke hu ua scrapers. Scrapers feem ntau muab faib ua cov scrapers sab hauv, sab nrauv scrapers thiab cov hniav scrapers. Lub scraper sab hauv feem ntau yog siv rau kev txiav ntoo, cov scraper txheej feem ntau yog siv rau txiav ntoo ntub, thiab cov hniav scraper feem ntau yog siv rau kev txiav los yog ntug banding saw hniav, tab sis lawv tsis tuaj yeem ua tau dav dav. Feem ntau, tus naj npawb ntawm cov scrapers tsim rau 10 ntiv tes los yog tsawg dua yog 24. Yuav kom ua kom muaj txiaj ntsig zoo tshaj plaws ntawm cov scrapers, feem ntau yog tsim nrog cov scrapers sab nraud. Tus naj npawb ntawm cov scrapers tsim rau 12 ntiv tes thiab siab dua yog 4-8, nrog ib nrab sab hauv scrapers thiab ib nrab txheej scrapers, symmetrical tsim. Multi-blade saw hniav nrog scrapers yog ib qho qauv. Cov tuam txhab txawv teb chaws tau tsim ntau cov hniav saw hniav nrog scrapers ua ntej. Thaum txiav cov ntoo ntub dej thiab cov ntoo tawv tawv, txhawm rau ua tiav cov txiaj ntsig zoo dua, cov sawb yuav raug txo kom hlawv flakes, ua kom cov nti tshem tawm lub peev xwm ntawm lub tshuab, txo cov sij hawm sib tsoo, thiab ua kom ntev. Txawm li cas los xij, nws yog ib qho nyuaj rau sharpen lub scraper ntawm ib tug ntau-blade saw nrog ib tug scraper. Cov khoom siv dav dav tsis tuaj yeem ua kom ntse, thiab tus nqi kuj tseem siab.
