1.Dab tsi yog cov teeb meem tseem ceeb hauv kev ua cov galvanized coils?
Tiv thaiv cov zinc txheej: Tiv thaiv khawb thiab tev, uas tuaj yeem cuam tshuam rau kev tiv thaiv corrosion.
Tswj burrs: Burrs tsim thaum shearing thiab stamping yuav tsum tau kho.
Lubrication: Lub lubricant tsim nyog yuav tsum tau xaiv thaum lub sij hawm stamping kom tsis txhob khawb thiab xyuas kom zinc txheej adhesion.
2.Dab tsi yog cov teeb meem tseem ceeb hauv kev ua cov hlau tungsten?
Kev tshem tawm cov khoom siv tsawg heev: Tsis muaj txiaj ntsig "txiav" tsis yooj yim sua; Kev tshem tawm tsuas yog nyob ntawm kev sib tsoo lossis hluav taws xob tawm machining (EDM) rau kev tshem tawm piecemeal.
Tus nqi siab: Cov khoom siv tshwj xeeb (EDM, cov tshuab sib tsoo) thiab cov khoom siv (pob zeb diamond log, electrodes) yog kim.
Yooj yim rau chipping thiab cracking: Vim nws cov brittleness siab, kev ntxhov siab tsis tsim nyog thaum ua tau yooj yim ua rau micro- tawg lossis chipping ntawm cov npoo thiab cov ces kaum.
Cov kev txwv tsis zoo: Kev tsim cov duab nyuaj yog qhov nyuaj heev; Feem ntau, tsuas yog geometry yooj yim tuaj yeem tsim lossis ua tiav ntawm EDM.
3.Nws nyuaj npaum li cas los ua cov galvanized coils?
Kev ua cov galvanized coils yog qhov tseem ceeb ntawm kev ua "me me hlau + mos txheej".
** Cov khoom siv hauv paus: ** Feem ntau qis - carbon txias- dov hlau xws li SPCC lossis DC01, nws muaj lub zog qis thiab tawv, zoo plasticity, thiab yooj yim heev rau deform thiab txiav.
** Txheej: ** Zinc txheej yog mos heev thiab nws lub luag haujlwm tseem ceeb yog kev tiv thaiv corrosion.
Yog li ntawd, qhov nyuaj ntawm kev ua nws tsis yog nyob rau hauv "txawm hais tias nws tuaj yeem ua tiav," tab sis nyob rau hauv "yuav ua li cas kom ua tau zoo":
** Zinc Layer Protection :** Thaum tuav, uncoiling, thiab sib sau, txhua qhov ntse khawb tuaj yeem ua rau zinc txheej, nthuav tawm cov hlau substrate thiab tsim qhov pib rau yav tom ntej xeb.
**Formability:** Txawm hais tias yooj yim rau daim ntawv, zinc txheej yuav tsim microcracks los yog tev tawm nyob rau hauv nruj nro los yog dabtsi yog khoov.
** Vuam : ** Thaum vuam galvanized qhov chaw, qhov kub ntawm zinc (kwv yees li 900 degree) qis dua qhov melting point ntawm hlau (kwv yees li 1500 degree). Thaum lub sij hawm vuam, zinc evaporates, tsim cov pa phem thiab ua rau muaj qhov tsis xws luag xws li porosity thiab slag inclusions hauv qhov vuam. Yuav tsum muaj cov txheej txheem tshwj xeeb (xws li kho qhov ntsuas thiab siv cov vuam hlau tshwj xeeb).
4.Nws nyuaj npaum li cas los ua cov hlau tungsten?
Vim nws tsis tshua muaj siab hardness, tsoos txiav txoj kev yog kiag li ineffective. Unconventional txoj kev yuav tsum tau ua hauj lwm:
Electrical Discharge Machining (EDM):
Electrical Discharge Machining (EDM): Txoj kev no siv cov khoom siv hluav taws xob rau hauv cov kua hluav taws xob (kerosene) los tsim cov hluav taws xob tawm ntawm cov electrode thiab cov tungsten carbide. Qhov kub siab tam sim ntawd (8000-12000 degree) hauv zos melts, vaporizes, thiab tshem tawm cov hlau. Qhov no yog thawj txoj kev rau machining complex-shaped tungsten carbide qhov chaw (xws li pwm kab noj hniav). Nws yog qeeb thiab kim.
Hlau EDM: Qhov no yog ib hom EDM uas siv cov hlau molybdenum txav raws li cov electrode, feem ntau yog siv rau ob - qhov ntev contour txiav.
Sib tsoo:
Kev sib tsoo yog ua los ntawm pob zeb diamond lossis CBN superhard sib tsoo lub log. Qhov no yog thawj txoj hauv kev kom ua tiav siab - qhov ntev thiab qhov ua tiav. Txawm li cas los xij, cov khoom tshem tawm tus nqi qis heev, thiab lub log hnav yog siab.
Bragging:
Cov khoom me me ntawm tungsten carbide inserts, twb zoo li ib daim ntawv tshwj xeeb, feem ntau yog brazed mus rau lub cuab yeej steel los tsim cov cuab yeej txiav (xws li cov cuab yeej tshuab dhos thiab milling cutters). Qhov no yog nws tus kheej ib hom "assembly" hom kev ua.
5.Dab tsi yog qhov txawv ntawm kev ua cov galvanized coils thiab ua cov tungsten hlau?
Kev ua cov galvanized coils zoo li txiav daim ntawv nrog ib khub ntawm txiab. Tus yuam sij yog txiav kom huv si tsis khawb daim ntawv.
Kev ua cov tungsten carbide zoo li polishing thiab carving pob zeb diamond nrog lwm lub pob zeb diamond. Koj tsuas tuaj yeem siv qee yam nyuaj, thiab nrog kev ua haujlwm qis heev, los tsim nws.
