Saib Buckle Ua Los ntawm Titanium Alloy Poob-Wax Casting

Poob -wax casting, tseem hu ua peev casting, yog ib txoj kev casting precision. Nws lub hauv paus ntsiab lus tseem ceeb yog ua ntej tsim cov qauv siv quav ciab nrog cov duab zoo ib yam li lub watch clasp, tom qab ntawd txheej txheej ntawm cov qauv siv quav ciab nrog ntau txheej txheej ntawm cov khoom siv refractory los tsim lub plhaub monolithic. Tom ntej no, lub plhaub yog rhuab, ua rau cov qauv siv quav ciab yaj thiab ntws tawm, tawm hauv cov kab noj hniav hauv lub plhaub uas phim cov duab ntawm lub moos. Thaum kawg, molten titanium alloy yog poured rau hauv lub kab noj hniav no, thiab tom qab nws txias thiab solidifies, lub plhaub yog tawg kom tau txais cov yam xav tau watch clasp. Cov txheej txheem no tuaj yeem tsim cov khoom siv nrog cov duab nyuaj thiab siab precision, ua rau nws zoo tagnrho rau cov khoom xws li watch clasps uas yuav tsum tau muaj qhov tseeb qhov tseeb thiab zoo li zoo.

Titanium alloy yog ib qho alloy uas muaj titanium ua lub hauv paus thiab lwm yam alloying ntsiab. Rau watch clasps, titanium alloy muaj ntau yam zoo. Ua ntej, nws qhov ceev yog tsawg, tsuas yog kwv yees li 60% ntawm cov hlau, ua rau lub moos sib zog thiab txo lub dab teg. Thib ob, titanium alloy muaj lub zog siab heev, muaj peev xwm tiv taus ntau yam sab nraud hauv kev siv niaj hnub, ua kom muaj kev ruaj khov thiab kev ntseeg siab ntawm lub clasp. Tsis tas li ntawd, titanium alloys muaj kev tiv thaiv corrosion zoo heev, ua rau lawv tsis tshua muaj xeb thiab corrosion nyob rau hauv qhov chaw ntub lossis hws, yog li ncua lub neej ntawm lub moos. Tsis tas li ntawd, titanium alloys yog biocompatible, tawv nqaij - tus phooj ywg, thiab haum rau cov neeg ntawm txhua hom tawv nqaij, txo qhov tshwm sim ntawm kev tsis haum tshuaj.

Ua ntej ploj lawm -wax casting ntawm lub watch clasp, yuav tsum tau ua tib zoo tsim. Tus txheej txheem tsim yuav tsum xav txog tag nrho cov qauv ntawm lub moos, hnav kev nplij siab, thiab kev ua haujlwm ntawm lub khawm. Piv txwv li, qhov qhib thiab kaw mechanism ntawm lub clasp yuav tsum yooj yim thaum ua kom muaj kev ruaj ntseg kaw. Raws li kev tsim cov duab kos, cov qauv siv quav ciab ntawm lub watch clasp yog tsim los ntawm cov khoom siv siv quav ciab. Qhov tseeb ntawm cov qauv siv quav ciab ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom kawg; yog li ntawd, siab - cov cuab yeej machining precision thiab cov kws tshaj lij yuav tsum tau ua. CNC machining thiab engraving txoj kev tuaj yeem siv los tsim cov qauv siv quav ciab, kom ntseeg tau tias qhov tseeb qhov tseeb thiab qhov chaw tiav raws li qhov xav tau.

Cov qauv siv quav ciab ua tiav yog tsau rau ntawm sprue bar los tsim cov pwm sib dhos. Tom qab ntawd cov pwm yog immersed nyob rau hauv refractory txheej, kom ntseeg tau ib tug uniform txheej txheej. Ib txheej ntawm cov xuab zeb refractory yog ces sprinkled on to top, thiab cov txheej txheem no yog rov ua dua ob peb zaug los tsim ib lub plhaub ntawm ib tug tej thickness. Qhov zoo ntawm lub plhaub yog qhov tseem ceeb rau kev ua kom zoo, xav tau lub zog txaus, thermal stability, thiab permeability. Kev sib txawv ntawm cov txheej txheej thiab cov xuab zeb cuam tshuam rau lub plhaub kev ua haujlwm thiab yuav tsum tau xaiv raws li cov yam ntxwv ntawm titanium alloy thiab cov txheej txheem casting. Thaum lub sij hawm txheej thiab xuab zeb thov, ua tib zoo tswj lub thickness thiab uniformity ntawm txhua txheej yog qhov tseem ceeb kom tsis txhob muaj qhov tsis xws luag xws li npuas thiab tawg.

Dewaxing thiab tua: Cov pwm nrog lub plhaub tau muab tso rau hauv lub tshuab dewaxing, qhov twg cua sov melts thiab tshem tawm cov qauv siv quav ciab. Lub dewaxing kub thiab lub sij hawm yuav tsum tau ua tib zoo tswj raws li cov yam ntxwv ntawm cov khoom siv quav ciab thiab lub plhaub tuab kom paub meej tias ua tiav melting thiab tshem tawm cov qauv siv quav ciab. Tom qab dewaxing, lub plhaub tau muab tso rau hauv qhov cub hluav taws kub kom siab - kub hnyiab. Kev tua hluav taws tshem tawm cov khoom seem thiab cov av noo ntawm lub plhaub, txhim kho nws lub zog thiab thermal stability. Kev tua hluav taws kub yog feem ntau ntawm 800 thiab 1200 degree, nrog rau qhov kub thiab lub sijhawm txiav txim siab raws li cov khoom ntawm cov pwm thiab cov txheej txheem casting.

Titanium Alloy Melting thiab Casting: titanium alloy raw khoom yog rhuab thiab melted siv lub tshuab nqus tsev induction melting rauv. Thaum lub sij hawm melting txheej txheem, lub melting kub, lub sij hawm, thiab cua sov cua yuav tsum nruj me ntsis tswj xyuas kom meej cov tshuaj muaj pes tsawg leeg thiab purity ntawm titanium alloy. Vim tias titanium alloys yog cov tshuaj lom neeg muaj zog thiab yooj yim ua rau cov ntsiab lus xws li oxygen thiab nitrogen hauv huab cua, cov txheej txheem melting yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev los yog inert gas tiv thaiv. Thaum cov titanium alloy yog tag nrho melted thiab ncav cuag qhov tsim nyog casting kub, nws yog sai poured rau hauv lub preheated pwm. Cov txheej txheem casting yuav tsum du thiab ceev kom tsis txhob muaj qhov tsis xws luag xws li tsis tiav filling lossis txias kaw.

Ncej -kev ua: Tom qab cov titanium alloy txias thiab solidifies, cov pwm tawg, thiab lub watch clasp raug tshem tawm. Lub clasp yog ntxuav kom tshem tawm cov pwm seem thiab oxide nplai los ntawm qhov chaw. Sandblasting thiab polishing tuaj yeem siv los ntxuav kom ua tiav qhov chaw du. Tom qab ntawd, lub clasp yog dimensionally thiab visually soj ntsuam xyuas kom nws ua tau raws li qhov yuav tsum tau tsim. Yog tias pom qhov sib txawv ntawm qhov sib txawv lossis qhov tsis xws luag, tuaj yeem tsim kho thiab kho kom haum. Thaum kawg, qhov kawg buckle tuaj yeem ua rau saum npoo - kho raws li qhov xav tau, xws li anodizing lossis electroplating, txhawm rau txhim kho nws cov hnav tsis kam, corrosion resistance, thiab zoo nkauj.
