Yuav ua li cas kom tawg tag hauv band saw hniav?

Nyob rau hauv kev sib tw ua lag luam ib puag ncig tam sim no, txhua leej txhua tus xav txo cov nqi thiab nce kev ua tau zoo, hauv daim ntawv thov sawing, qee cov neeg xav tias txo cov khoom siv hluav taws xob los yog saw hniav ib tus nqi tuaj yeem txo cov nqi tsim khoom, qhov tseeb, qhov kev pom no tsis yog lawm. Tsuas yog txo cov peev txheej ruaj khov lossis tus nqi ntawm ib qho cuab yeej tsis tuaj yeem ua tiav lub hom phiaj ntawm kev txo nqi thiab kev ua haujlwm zoo, tab sis los ntawm cov txheej txheem tsim khoom thiab kev ua haujlwm zoo dua thiab kev tswj xyuas cov txheej txheem sawing, nws tuaj yeem ua tiav qhov no. lub hom phiaj. Cia peb tham kom ntxaws txog yuav ua li cas zom cov saw hniav thiab lub hauv paus ntsiab lus ntawm kev sib tsoo. 1. Yuav ua li cas khiav cov saw hniav nyob rau hauv cov txheej txheem sawing, siab sawing txhais tau tias kom txo tau qhov zaus ntawm kev hloov cov saw hniav, txo lub sij hawm downtime ntawm lub sawing tshuab, yog hais tias cov saw hniav thiab sawing tsis raug xaiv nyob rau hauv lub premise ntawm lub saw hniav thiab sawing tsis, nws yuav tsum muaj peev xwm kom txo tau lub downtime. Txawm li cas los xij, cov khoom sib txawv ntawm cov saw hniav sib txawv, xws li bimetal band saw hniav thiab carbide band pom hniav, nws txoj kev khiav-hauv kev tsis zoo ib yam, thiab cov khoom sib txawv thiab cov khoom siv, kev xaiv ntawm kev khiav-hauv qhov yuav tsum sib txawv. Thawj yog los txiav txim siab thawj zaug sawing ceev, bimetallic band saw hniav nyob rau hauv sawing carbon steel thiab annealed lub xeev ntawm qis thiab nruab nrab alloy, sawing ceev yuav nyob twj ywm unchanged, xws li 200mm loj 45 khoom steel siv 70m / min ceev, 42CrMo siv 50m / min ceev. Yog hais tias nws yog sawing kav nrog phab ntsa thickness hauv qab 20 hli los yog qhov twg cov clamping tsis muaj zog, lub sawing ceev yuav tsum raug txo kom tsawg tshaj li 80%. Yog tias sawing steel nrog tawv tawv lossis cov ntaub ntawv uas muaj hardness siab dua 30HRC, qhov nrawm nrawm kuj yuav tsum tau txo qis dua 80%, tau kawg, thaum sawing steel nrog tawv tawv, siv cov khoom tsis muaj tawv tawv ua ntej. Carbide band pom hniav nyob rau hauv qhov khiav-hauv, feem ntau txo cov kab ceev mus txog 50% ntawm tus nqi ib txwm, tab sis high-speed aluminium alloy band pom feem ntau tsis tas yuav txo cov kab ceev. Tsis tas li ntawd, qhov pub ceev yog teem. Yog tias nws yog cov khoom siv ntau tshaj 100mm thiab cov yeeb nkab ntawm ntau tshaj 20mm phab ntsa thickness, cov bimetal band pom hniav pub ceev yog txo mus rau 50% ntawm nws ib txwm ceev, thiab cov cemented carbide band saw hniav yuav pib teem lub ceev ceev. mus rau 10%, thiab tom qab ntawd maj mam nce qhov pub ceev, kho upward yam tsis muaj kev vibration raws li tus qauv, yog tias qhov kev vibration, Cia li txo qhov pub me ntsis thiab khiav mus rau ib ntus kom txog thaum pub ceev nce mus txog 50%. Yog tias nws yog cov yeeb nkab uas muaj phab ntsa thickness tsawg dua 20 hli, qhov nrawm nrawm yuav tsum tau muab xam ntxiv raws li qhov pub qhov tob ntawm txhua tus hniav. Pub ceev =40* band pom kab ceev *TPI * Txheem pub qhov tob rau ib tus hniav pub ceev: hli/min Band pom kab ceev: m/minTPI: suab ntawm cov hniav, 3/4 hloov cov hniav mus rau 3.5,1.4/2.0 cov hniav rau 1.7, thiab lwm yam. Txhua qhov tob ntawm cov khoom sib txawv yuav txawv, qhov ntau ntawm 0.02 thiab 0.05mm, tag nrho pub rau ib tus hniav yuav tsum qis dua nws cov khoom noj ib txwm.
Kev pub ceev tsis tuaj yeem teeb tsa qis dhau, yog tias tus nqi pub tsawg dhau rau lub sijhawm ntev ntawm cov khoom siv tawv tawv (xws li stainless hlau), nws yuav ua rau mob hnyav ntawm cov hniav thiab cuam tshuam rau lub neej ntawm cov hniav. .
Tom qab thawj kab ceev thiab pub ceev tau teeb tsa thiab khiav hauv ib lub sijhawm, cov kab ceev thiab pub ceev tau maj mam nce mus rau qhov qub nqi raws li qhov chaw uas qhov kev vibration tsis nce. Qhov thib peb, tag nrho cov khiav-hauv cheeb tsam yog txiav txim siab, qhov khiav-hauv cheeb tsam thiab sawing cov ntaub ntawv kuj muaj feem xyuam nrog, cov ntaub ntawv mos xws li qis thiab nruab nrab carbon steel thiab aluminium alloy, khiav-hauv cheeb tsam ntawm 320cm2 mus rau 640cm2, roughly sib npaug rau 100mm txoj kab uas hla. puag ncig steel 4 mus rau 8; Qhov sib tsoo ntawm qhov nyuaj ntawm cov ntaub ntawv txiav yuav tsum raug txo kom zoo, thiab tag nrho cheeb tsam yog li 160cm2 txog 480cm2, uas yog hais txog 2 riam mus rau 6 riam ntawm cov hlau puag ncig nrog txoj kab uas hla ntawm 100mm. Nyob rau hauv luv luv, qhov tseeb khiav-nyob rau hauv lub saw hniav muaj ob lub hauv paus ntsiab lus: 1. Tswj lub vibration thaum sawing; 2, tswj tus nqi pub rau ib tus hniav kom qis dua tus nqi pub noj ib txwm (qhov no muaj feem xyuam nrog kev sib txuam ntawm kab nrawm thiab pub ceev, tsis yog cuam tshuam rau kev pub ceev). Tom qab lub saw saw yog khiav hauv, lub suab sawing yuav raug txo, ntxiv rau, qhov chaw ntawm lub workpiece yuav smoother. Yog hais tias tus tshiab txiav ntug yog khiav nyob rau hauv ib txwm, cov me me burrs ntawm cov txiav npoo yuav passivated, thiab tag nrho cov hniav hau yuav tsim ib tug rounded ces kaum, kom tag nrho cov seem ntawm txiav ntug yuav sib npaug zos rau kev txiav thaum lub sij hawm ib txwm txiav. lub sij hawm tom qab. Thiab yog hais tias lub sawb tshiab tsuas yog nyob rau hauv lub tshuab sawing yuav muaj zog txiav, ces cov me me burrs vim muaj kev cuam tshuam loj heev, yuav raug tshem tawm sai sai ntawm ntug txiav, nws raug tshem tawm tsis yog los ntawm nws tus kheej xwb, tab sis kuj nrog ib feem ntawm lub cev ntawm kev txiav ntug, uas ua rau muaj qhov sib txawv loj heev thaum lub txiav ntug nyuam qhuav pib, peb txoj kev lag luam hu ua "tooth collapse" lossis "tooth tip micro-collapse", Thaum txiav ntug txiav rau hauv lub sijhawm tom qab, ntau qhov chaw ntawm kev txiav ntug tsis tuaj yeem sib npaug ntawm lub zog, thiab tom qab ntawd cuam tshuam rau tag nrho band pom lub neej. Yog tias cov neeg nyeem tseem muaj kev tsis txaus siab txog kev khiav-hauv, thov xa mus rau peb cov kev paub dhau los ntawm cov xaum tom qab teev, koj puas xav tias cov xaum tshiab tshiab yuav tsum tau maj mam rubbed rau ntawm daim ntawv ua ntej, thiab cov lus qhia yuav zoo kom poob ntau tom qab me ntsis passivation. ? Qhov no yog lub hauv paus ntsiab lus ntawm saw hniav khiav-hauv. Carbide band pom hniav sawing, tshwj xeeb tshaj yog them nyiaj rau kev khiav-hauv, vim hais tias lub taub hau alloy yog nkig heev, yog tias qhov txiav ntug tsis sib xws, qhov tshwm sim ntawm cov hniav tawg yuav hnyav dua. Daim duab hauv qab no qhia txog qhov xwm txheej ntawm cov hniav tawg ntawm qhov kawg ntawm cov hniav hlau uas tsis tau khiav hauv.
Cov ntaub ntawv sib txawv thiab cov kev ua haujlwm sib txawv pom cov hniav khiav-hauv cov txheej txheem yuav txawv me ntsis. Yog tias tus neeg siv xav tshuaj xyuas seb cov saw hniav khiav-hauv qhov zoo li cas, nws tuaj yeem yuav lub iav tsom iav los yog tsom iav ntawm 10 mus rau 20 zaug, xyuas cov hniav tom qab khiav-hauv, thiab tom qab ntawd txiav txim siab cov txheej txheem khiav-hauv kev sib txawv. cov ntaub ntawv ntawm nws tus kheej. Lub tshuab nqus tsev nqus pom cov hniav siv los soj ntsuam lub hau ntawm cov hniav tuaj yeem ua kom lub neej ntev ntawm cov saw hniav los ntawm 20% lossis ntau dua, txawm tias qee cov tuam txhab lag luam tam sim no pom cov hniav passivation kev kho mob, tab sis txhawm rau ua kom lub neej ib txwm muaj. cov saw hniav, nws raug nquahu kom cov neeg siv khoom yuav tsum tshawb nrhiav ntau txoj hauv kev los siv txhua lub saw hniav, txhawm rau ua tiav lub hom phiaj ntawm kev siv cov saw hniav.
