Yuav ua li cas xaiv bimetal band saw hniav
Band saw hniav tau dhau los ua ntau thiab siv ntau dua. Cov cuab yeej sawing sawv cev los ntawm ob-hlau band saw hniav yog cov cuab yeej tseem ceeb hauv kev tsim tsheb, hlau metallurgy, forging loj, aerospace, nuclear fais fab thiab lwm yam kev tsim khoom. Txawm li cas los xij, ntau tus neeg yuav khoom feem ntau tsis paub yuav xaiv li cas thaum yuav cov saw hniav. Tam sim no peb yuav qhia rau koj paub meej yuav ua li cas xaiv ob hlau band saw hniav:
1. Xaiv cov saw hniav specifications.
Band pom hniav specifications peb feem ntau xa mus rau qhov dav, thickness, thiab ntev ntawm band saw hniav.
Feem ntau dav thiab thicknesses ntawm ob-hlau band saw hniav yog:
13*0.65mm
19*0.9mm
27*0.9mm
34*1.1mm
41*1.3mm
54*1.6mm
67*1.6mm
Qhov ntev ntawm band saw hniav feem ntau yog txiav txim raws li lub tshuab saw siv. Yog li ntawd, thaum xaiv cov specifications ntawm ib tug band sawb, koj yuav tsum xub paub qhov ntev thiab dav ntawm cov saw hniav siv los ntawm koj lub tshuab sawing.
2. Xaiv lub kaum sab xis thiab cov hniav ntawm cov saw hniav.
Cov khoom sib txawv muaj qhov sib txawv txiav nyuaj. Qee cov ntaub ntawv nyuaj, qee qhov yog nplaum, thiab cov yam ntxwv sib txawv muaj cov kev xav tau sib txawv rau lub kaum sab xis ntawm cov saw hniav. Raws li cov hniav sib txawv ntawm cov ntaub ntawv txiav, lawv muab faib ua: cov hniav txheej txheem, cov hniav tensile, vaub kib cov hniav thiab cov hniav nyiaj hniav kub, thiab lwm yam.
Cov hniav txheem yog tsim rau feem ntau cov ntaub ntawv hlau. Xws li cov qauv hlau, carbon steel, zoo tib yam alloy steel, cam khwb cia hlau, thiab lwm yam.
Tensile hniav yog tsim rau hollow thiab irregular-puab cov ntaub ntawv. Xws li nyias-walled profiles, I-beams, thiab lwm yam.
Vaub kib rov qab cov hniav yog tsim rau kev txiav loj loj tshwj xeeb-zoo li tus profiles thiab cov ntaub ntawv mos. Xws li aluminium, tooj liab, alloy tooj liab, thiab lwm yam.
Ob chav rov qab lub kaum sab xis hniav muaj qhov cuam tshuam loj heev thaum ua cov kav dej loj loj.
3. Xaiv cov hniav ntawm cov saw hniav.
Nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tsim nyog cov hniav ntawm cov saw hniav raws li qhov loj ntawm cov khoom. Nws yog ib qho tsim nyog kom nkag siab qhov loj ntawm cov khoom siv sawed. Rau cov ntaub ntawv loj, cov hniav loj yuav tsum tau siv los tiv thaiv cov hniav ntawm cov hniav kom tuab heev thiab cov hlau sharpener tsis tuaj yeem tawm ntawm cov hniav. Rau cov khoom me me, nws yog qhov zoo tshaj plaws los siv cov hniav me me kom tsis txhob muaj kev txiav txim los ntawm cov hniav saw. loj dhau lawm.
Cov hniav pitch yog muab faib ua 8/12, 6/10, 5/8, 4/6, 3/4, 2/3, 1.4/2, 1/1.5, 0.75/1.25. Rau cov ntaub ntawv sib txawv, xaiv cov hniav tsim nyog kom ua tiav cov txiaj ntsig zoo dua. Piv txwv li:
Cov khoom siv yog 45 # round steel nrog txoj kab uas hla ntawm 150-180mm
Nws raug nquahu kom xaiv cov saw hniav nrog cov hniav ntawm 3/4.
Cov khoom siv yog pwm hlau nrog lub cheeb ntawm 200-400mm
Nws raug nquahu kom xaiv cov saw hniav nrog cov hniav ntawm 2/3.
Cov khoom siv yog stainless hlau yeeb nkab nrog lub cheeb ntawm 120mm thiab phab ntsa thickness ntawm 1.5mm, ib qho kev txiav.
Nws raug nquahu kom xaiv cov saw hniav nrog lub suab ntawm 8/12.
