Qhov txawv ntawm txhuam stainless hlau thiab polished!
Nyob rau hauv cov nqe lus ntawm kev siv tshuab, cov txheej txheem kev kos duab yog ua kom muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw ntawm lub workpiece.Cov qauv kos duab dav dav yog: nyias kab txaij thiab voj voog.Cov txheej txheem polishing yog ua rau saum npoo ntawm lub workpiece kom tiaj tus, tsis muaj qhov tsis zoo, thiab nws zoo li du thiab translucent, nrog daim iav saum npoo.
Nyob rau hauv cov nqe lus ntawm tsab ntawv tsa suab, dab tsi cov txheej txheem ntawm cov hlau kos duab ua rau ntawm cov cuab yeej yog qhov rov ua dua, thaum lub polishing txheej txheem yog lub zog khiav ntawm lub tiaj polishing tshuab.Qhov ob yog qhov sib txawv ntawm txoj cai thiab txawv ntawm kev coj ua.
Hauv kev tsim khoom, cov txheej txheem kev kos duab hlau yog siv rau kev kos duab, thiab muaj ntau yam khoom siv polishing raws li cov duab sib txawv kom haum rau cov kev xav tau sib txawv.
Yog tias lub workpiece yuav tsum tau kos thiab polished, cov txheej txheem twg yuav tsum tau ua raws li qhov dhau los?
Los ntawm qhov xwm txheej no, los ntawm cov txiaj ntsig ntawm kev kos duab thiab polishing ntawm qhov chaw kho mob, nrog rau cov txheej txheem txheej txheem, nws tsis yooj yim rau peb kos: polishing ua ntej, xaim kos duab tom qab.Tsuas yog tom qab qhov saum npoo ntawm lub workpiece yog polished thiab flattened, cov hlau kos duab tuaj yeem nqa tawm, vim tias tsuas yog nyob rau hauv txoj kev no cov nyhuv ntawm cov duab kos yuav zoo, thiab cov kab kos duab yuav zoo ib yam.Polishing yog rau txhuam thiab teeb lub hauv paus.Nyob rau hauv ib lo lus, yog hais tias cov hlau yog polished ua ntej, tsis yog tsuas yog cov hlau kos duab nyhuv yog tsis zoo, tab sis cov zoo hlau kos duab kab yuav nyob rau hauv tag nrho cov av los ntawm kev sib tsoo disc thaum polishing, yog li tsis muaj ib tug thiaj li hu ua hlau drawing nyhuv.
Kev ceev faj rau daim ntawv hlau stainless hlau hlau kos duab
1. Brushed (frosted): Feem ntau, lub xeev saum npoo yog cov kab ncaj (tseem hu ua frosted) tom qab ua tiav los ntawm kev sib txhuam ntawm cov hlau tsis huv, nrog rau cov hlau kos duab, thiab kab thiab ripples.
Kev ua tau zoo tus qauv: lub thickness ntawm cov kev ntxhib los mos yog uniform thiab uniform, kev ntxhib los mos ntawm txhua sab ntawm cov khoom yog ntuj thiab zoo nkauj raws li tus tsim thiab kev tsim kho, thiab dabtsi yog khoov txoj hauj lwm ntawm cov khoom raug tso cai kom muaj ib tug me ntsis chaotic zoo nkauj. tsis cuam tshuam rau qhov tsos.
- Cov txheej txheem ntawm kev kos duab:
(1) Cov nplej uas tsim los ntawm ntau hom ntawv xuab zeb sib txawv.Qhov loj ntawm cov ntawv xuab zeb, cov nplej nyias nyias, qhov tob ntawm cov nplej.Ntawm qhov tsis sib xws, cov ntawv xuab zeb
Tus qauv me dua, qhov tuab ntawm cov xuab zeb yuav yog, qhov tob qhov kev ntxhib los mos yuav yog.Yog li ntawd, cov qauv ntawm cov ntawv xuab zeb yuav tsum tau qhia rau ntawm daim duab engineering.
(2) Kev kos duab xaim yog kev taw qhia: nws yuav tsum tau qhia nyob rau hauv daim duab engineering seb nws yog ncaj los yog kab rov tav hlau kos duab (sawv cev los ntawm ob xub).
(3) Daim duab kos duab ntawm lub workpiece yuav tsum tsis txhob muaj qhov tsa ceg, txwv tsis pub cov khoom seem yuav flattened.
Lus Cim: Feem ntau, tom qab kos hlau, electroplating, oxidation, thiab lwm yam yuav tsum tau ua.Xws li: hlau plating, aluminium oxidation.Vim yog qhov tsis xws luag ntawm lub tshuab kos duab hlau, thaum muaj qhov loj me ntawm cov khoom me me thiab cov khoom ua haujlwm, yuav tsum xav txog kev tsim cov hlau kos duab jig., kom tsis txhob muaj qhov tsis zoo ntawm lub workpiece tom qab xaim kos duab.
- Hlau kos tshuab muaj nuj nqi thiab ceev faj
Ua ntej kos duab, lub tshuab kos duab yuav tsum tau kho kom haum rau qhov siab raws li qhov tuab ntawm cov khoom.
Qhov qeeb qeeb ntawm txoj siv conveyor, qhov sib tsoo zoo dua, thiab rov ua dua.Yog tias qhov tob ntawm qhov pub ntau dhau, qhov chaw ntawm lub workpiece yuav raug hlawv, yog li txhua qhov pub yuav tsum tsis txhob ntau dhau, nws yuav tsum yog li 0.05 hli.
Yog hais tias lub siab ntawm lub tog raj kheej nias me dhau, lub workpiece yuav tsis raug nias nruj, thiab lub workpiece yuav raug pov tawm los ntawm lub zog centrifugal ntawm cov menyuam.Yog tias qhov siab dhau lawm, kev sib tsoo kuj yuav nce ntxiv thiab cov nyhuv sib tsoo yuav cuam tshuam.Qhov zoo ntawm daim duab dav ntawm lub tshuab nqus hlau tsis tshaj 600mm.Yog tias qhov kev taw qhia tsawg dua 600mm, koj yuav tsum tau them sai sai rau cov duab kos, vim tias qhov kev taw qhia yog raws li cov khoom noj khoom noj.
Kev ceev faj rau cov ntawv hlau stainless hlau polishing
Brightness qib ntawm stainless hlau tom qab polishing Los ntawm kev tshuaj xyuas qhov muag, qhov ci ntsa iab ntawm qhov chaw polished yog muab faib ua 5 qib:
Qib 1: Muaj cov yeeb yaj kiab oxide dawb rau ntawm qhov chaw, tsis muaj qhov ci;
Theem 2: Ci ntsa iab me ntsis, cov qauv tsis tuaj yeem pom meej;
Qib 3: Kev ci ntsa iab zoo dua, cov qauv tuaj yeem pom;
Qib 4: Qhov saum npoo yog ci, thiab cov qauv tuaj yeem pom tau meej (sib npaug rau qhov zoo ntawm electrochemical polishing);
Qib 5: Daim iav zoo li qhov ci.
Cov txheej txheem dav dav ntawm mechanical polishing yog raws li hauv qab no:
(1) Rough pov
Tom qab milling, EDM, sib tsoo thiab lwm yam txheej txheem, qhov saum npoo tuaj yeem polished los ntawm kev sib hloov nto polishing tshuab lossis lub tshuab sib tsoo ultrasonic nrog kev sib hloov ceev ntawm 35 000-40 000 rpm.Txoj kev siv feem ntau yog siv lub log nrog txoj kab uas hla Φ 3mm thiab WA # 400 kom tshem tawm cov txheej EDM dawb.Tom qab ntawd muaj phau ntawv whetstone sib tsoo, sawb whetstone nrog kerosene ua cov roj nplua nyeem lossis cov khoom ua kom txias.Qhov kev txiav txim dav dav ntawm kev siv yog # 180 ~ # 240 ~ # 320 ~ # 400 ~ # 600 ~ # 800 ~ # 1000 .Ntau tus moldmakers xaiv pib nrog #400 kom txuag sijhawm.
(2) Semi-zoo polishing
Semi-fine polishing tsuas yog siv cov ntawv xuab zeb thiab kerosene.Cov naj npawb ntawm cov ntawv xuab zeb yog: # 400 ~ # 600 ~ # 800 ~ # 1000 ~ # 1200 ~ # 1500.Qhov tseeb, #1500 sandpaper tsuas yog tsim rau hardening tuag steel (thov 52HRC), tsis yog rau pre-hardened steel, vim hais tias nws yuav ua rau saum npoo ntawm pre-hardened hlau hlawv.
(3) Zoo polishing
Fine polishing mas siv pob zeb diamond abrasive muab tshuaj txhuam.Yog tias koj siv lub log polishing los sib xyaw cov pob zeb diamond sib tsoo hmoov los yog cov khoom sib tsoo rau kev sib tsoo, qhov sib tsoo ib txwm yog 9 μm (# 1800) ~ 6 μm (# 3000) ~ 3 μm (# 8000).A 9 μm pob zeb diamond muab tshuaj txhuam thiab polishing daim ntaub log tuaj yeem siv los tshem tawm cov cim plaub hau ntawm # 1200 thiab # 1500 cov ntawv xuab zeb.Tom qab ntawd txhuam nrog cov nplaum nplaum thiab pob zeb diamond abrasive muab tshuaj txhuam, hauv kev txiav txim ntawm 1 μm (# 14000) ~ 1/2 μm (# 60000) ~ 1/4 μm (# 100000).Polishing txheej txheem uas yuav tsum tau precision siab tshaj 1 μm (xws li 1 μm) tuaj yeem ua tiav hauv chav polishing huv hauv khw pwm.Txhawm rau polishing meej dua, yuav tsum muaj qhov chaw huv huv.Plua plav, fumes, dandruff thiab drool tag nrho cov muaj peev xwm mus undo lub high-precision polished tiav koj tau txais tom qab teev ua hauj lwm.
Mechanical polishing: Siv lub tshuab abrasive siv polishing los txhuam cov menyuam thav duab.Ua ntej, siv 120 # abrasive siv.Thaum cov xim saum npoo mus txog thawj zaug, hloov 240 # abrasive siv.Thaum cov xim saum npoo mus txog thawj zaug, hloov 800 # abrasive siv.Thaum cov xim nto tuaj txog, hloov 1200 # abrasive siv, thiab muab pov rau cov nyhuv ntawm cov hniav stainless hlau phaj.
Kev ceev faj rau stainless hlau polishing
Sib tsoo nrog cov ntawv xuab zeb lossis siv abrasive hauv kev sib tsoo yog qhov ua haujlwm polishing, tawm hauv cov kab zoo heev ntawm cov phaj hlau.Muaj teeb meem nrog alumina raws li abrasive, ib feem yog vim muaj teeb meem siab.Txhua qhov abrasive ntawm cov khoom siv, xws li abrasive siv thiab sib tsoo lub log, yuav tsum tsis txhob siv rau lwm cov ntaub ntawv tsis-stainless steel ua ntej siv.Vim tias qhov no yuav ua rau cov hlau tsis huv.Txhawm rau kom ua tiav qhov zoo sib xws, lub log tshiab lossis siv yuav tsum tau sim ntawm cov khoom seem ntawm tib qho kev sib xyaw kom cov qauv zoo sib xws.
