Burrs nyob txhua qhov chaw hauv cov txheej txheem hlau.Tsis muaj teeb meem npaum li cas cov cuab yeej precision koj siv, nws yuav yug los ua ke nrog cov khoom.Nws yog ib yam ntawm cov hlau ntau dhau ntawm cov ntaub ntawv tsim tawm ntawm cov txheej txheem ntawm cov khoom yuav tsum tau ua tiav vim cov yas deformation ntawm cov khoom.Tshwj xeeb tshaj yog cov ntaub ntawv uas zoo ductility los yog toughness yog tshwj xeeb tshaj yog prone rau burrs.
Lub hom phiaj tseem ceeb ntawm burrs muaj xws li flash burrs, lub kaum ntse ntse burrs, spatter thiab lwm yam hlau seem uas tsis tau raws li cov khoom tsim.Hais txog qhov teeb meem no, tsis muaj txoj hauv kev zoo los tshem tawm nws hauv cov txheej txheem tsim khoom kom deb li deb.Yog li ntawd, txhawm rau txhawm rau txhawm rau tsim cov khoom tsim nyog, cov kws ua haujlwm tsuas tuaj yeem ua haujlwm nyuaj ntawm kev tshem tawm cov txheej txheem rov qab.Txog tam sim no, cov khoom sib txawv muaj cov kev xav tau sib txawv.Muaj ntau txoj hauv kev thiab cov cuab yeej siv los tshem tawm cov burrs.
Xinfa CNC cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis.Yog xav paub ntxiv, thov mus saib:
Tuam Tshoj CNC cuab yeej Hoobkas thiab cov chaw muag khoom (xinfatools.com)
Feem ntau hais lus, txoj kev tshem tawm burr tuaj yeem muab faib ua plaub pawg:
1. Coarse Level (hloov tiv tauj)
Nyob rau hauv pawg no yog txiav, sib tsoo, ua ntaub ntawv thiab scraper ua.
2. Qib ib txwm (mos kov)
Nyob rau hauv pawg no yog siv sib tsoo, sib tsoo, elastic log sib tsoo thiab polishing.
3. Precision theem (kev sib cuag tau yooj yim)
Nyob rau hauv pawg no yog dej ntws ua, electrochemical ua, electrolytic sib tsoo thiab dov ua.
4. Ultra-precision theem (precision tiv tauj)
Nyob rau hauv pawg no yog abrasive flow deburring, sib nqus sib nqus deburring, electrolytic deburring, thermal deburring thiab ntom radium haib ultrasonic deburring, thiab lwm yam.
Thaum peb xaiv txoj kev deburring, peb yuav tsum xav txog ntau yam, xws li cov yam ntxwv ntawm cov khoom, cov qauv zoo, qhov loj thiab qhov tseeb.Tshwj xeeb, peb yuav tsum tau them sai sai rau kev hloov pauv ntawm qhov roughness, qhov ntev ntev, deformation, thiab kev ntxhov siab seem.
Lub npe hu ua electrolytic deburring yog ib txoj kev siv tshuaj tua kab mob.Nws tuaj yeem tshem tawm burrs tom qab machining, sib tsoo thiab stamping, thiab puag ncig lossis chamfer cov npoo ntse ntawm cov hlau.
Ib txoj kev ua electrolytic uas siv electrolysis tshem tawm cov burrs ntawm cov hlau, hu ua ECD hauv lus Askiv.Kho cov cuab yeej cathode (feem ntau yog ua los ntawm tooj dag) nyob ze ntawm qhov burr ntawm lub workpiece, nrog rau qee qhov sib txawv (feem ntau 0.3 txog 1 hli) ntawm lawv.Cov khoom siv hluav taws xob ntawm cov cuab yeej cathode yog ua raws li cov ntug burr, thiab lwm qhov chaw yog them nrog ib txheej insulating kom mloog zoo rau cov electrolysis ntawm qhov burr.
Thaum lub sijhawm ua haujlwm, lub cathode ntawm lub cuab yeej txuas nrog rau qhov tsis zoo ntawm DC fais fab mov, thiab lub workpiece txuas nrog rau tus ncej zoo ntawm DC fais fab mov.Ib qho hluav taws xob tsis tshua muaj siab (feem ntau yog sodium nitrate lossis sodium chlorate aqueous tov) nrog lub siab ntawm 0.1 txog 0.3 MPa ntws ntawm cov khoom ua haujlwm thiab cov cathode.Thaum lub DC fais fab mov qhib, cov burrs yuav yaj nyob rau hauv lub anode thiab raug tshem tawm, thiab yuav muab tshem tawm los ntawm electrolyte.
Cov electrolyte yog corrosive rau ib qho twg, thiab lub workpiece yuav tsum tau ntxuav thiab xeb-pov thawj tom qab deburring.Electrolytic deburring yog tsim rau tshem tawm burrs los ntawm tus ntoo khaub lig qhov nyob rau hauv zais qhov chaw los yog qhov chaw nrog complex duab.Nws muaj kev ua haujlwm siab ntau lawm thiab lub sijhawm deburring feem ntau tsuas yog siv ob peb feeb mus rau kaum vib nas this.
Txoj kev no feem ntau yog siv rau kev deburring gears, splines, txuas rods, valve lub cev thiab crankshaft roj qhov qhib, nrog rau lub kaum ntse ntse rounding, thiab lwm yam. Qhov tsis zoo yog tias qhov chaw nyob ze ntawm lub burrs tseem cuam tshuam los ntawm electrolysis, thiab qhov chaw yuav poob nws thawj luster thiab txawm cuam tshuam rau qhov tseeb qhov tseeb.
Tau kawg, ntxiv rau electrolytic burr tshem tawm, kuj tseem muaj cov hauv qab no tshwj xeeb burr tshem tawm txoj kev:
1. Abrasive ntws deburring
Abrasive flow machining thev naus laus zis (AFM) yog cov txheej txheem tshiab thiab tshem tawm cov txheej txheem tsim tawm txawv teb chaws thaum xyoo 1970s.Cov txheej txheem no yog tshwj xeeb tshaj yog haum rau burrs uas nyuam qhuav nkag mus rau hauv lub finishing theem, tab sis nws tsis yog haum rau me me thiab ntev qhov thiab hlau pwm nrog blocked bottoms.thiab lwm yam tsis haum rau kev ua.
2. Sib nqus sib tsoo thiab deburring
Txoj kev no tau tshwm sim nyob rau yav dhau los Soviet Union, Bulgaria thiab lwm lub tebchaws European sab hnub tuaj hauv xyoo 1960.Nyob rau hauv nruab nrab-1980s, Japanese manufacturers tau ua qhov kev tshawb fawb tob ntawm nws cov txheej txheem thiab daim ntawv thov.
Thaum lub sij hawm sib nqus sib nqus, lub workpiece yog muab tso rau hauv magnetic teb tsim los ntawm ob tug sib nqus ncej, thiab sib nqus abrasives yog muab tso rau hauv qhov sib txawv ntawm lub workpiece thiab cov hlau nplaum.Cov abrasives yog npaj kom huv si raws li cov kev taw qhia ntawm cov kab sib nqus nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb quab yuam, tsim ib tug mos mos thiab nruj sib nqus sib tsoo tshuab.Txhuam, thaum lub workpiece rotates thiab vibrates axially nyob rau hauv lub magnetic teb, lub workpiece thiab abrasive txav mus rau ib tug txheeb ze, thiab abrasive txhuam grinds nto ntawm lub workpiece;txoj kev sib nqus sib nqus tuaj yeem sib tsoo thiab deburr qhov chaw tau zoo thiab nrawm, thiab tsim nyog rau Nws yog txoj kev ua tiav nrog kev nqis peev tsawg, kev ua haujlwm siab, kev siv dav thiab zoo rau qhov chaw ua los ntawm ntau yam ntaub ntawv, qhov ntau thiab tsawg thiab cov qauv.
Tam sim no, cov teb chaws txawv teb chaws tuaj yeem zom thiab tshem tawm qhov chaw sab hauv thiab sab nraud ntawm lub cev rotating, qhov chaw tiaj tus, iav hniav, qhov chaw nyuaj, thiab lwm yam, tshem tawm cov nplai oxide ntawm cov xov hlau, thiab ntxuav cov ntawv luam tawm hauv Circuit Court, thiab lwm yam.
3. Thermal deburring
Thermal deburring (TED) siv cov kub kub uas tsim los ntawm cov deflagration ntawm cov sib tov ntawm hydrogen thiab oxygen gas los yog oxygen thiab natural gas los hlawv tawm cov burrs.Nws yog kom dhau cov pa oxygen thiab cov pa oxygen lossis cov pa roj carbon monoxide thiab cov pa rau hauv lub thawv kaw, thiab ignite nws los ntawm lub qhov hluav taws xob, kom cov sib tov tawg nyob rau hauv ib qho instant thiab tso tawm ntau lub zog kub kom tshem tawm cov burrs.Txawm li cas los xij, tom qab lub workpiece tau tawg tawg, nws cov hmoov oxidized yuav ua raws li qhov chaw ntawm lub workpiece thiab yuav tsum tau ntxuav los yog pickled.
4. MiLa haib ultrasonic deburring
MiLa muaj zog ultrasonic deburring tshuab yog ib txoj kev deburring uas tau nrov nyob rau hauv xyoo tas los no.Kev tu ib leeg yog 10 mus rau 20 npaug ntawm cov tshuab ntxuav ultrasonic zoo tib yam.Cov qhov sib npaug sib npaug hauv lub tank dej, tshem tawm qhov xav tau ntawm kev tu ultrasonic.Cov koob tshuaj tuaj yeem ua tiav ib txhij hauv 5 mus rau 15 feeb.
