Me Module Gears, Titanium Alloy Poob-Wax Casting

Cov iav me me feem ntau xa mus rau cov iav nrog lub module tsawg dua 1 hli. Lawv yog cov me me thiab xav tau high precision. Lawv tau dav siv nyob rau hauv precision machinery, instrumentation, thiab aerospace teb, xws li me me kis systems nyob rau hauv aerospace cov cuab yeej thiab precision kis tau tus mob qauv hauv cov twj paj nruag. Vim lawv qhov me me, cov txheej txheem machining ib txwm yuav tsis txaus los ua kom tau raws li kev tsim khoom ntawm kev ua haujlwm siab thiab cov duab nyuaj.

Titanium alloys have advantages such as low density, high specific strength, and good corrosion resistance. Lawv tau siv dav hauv aerospace, biomedical, thiab lwm yam. Rau cov khoom siv me me, siv cov titanium alloys tuaj yeem txo qhov hnyav thaum ua kom muaj zog iav, yog li txhim kho tag nrho cov khoom siv. Txawm li cas los xij, titanium alloys nyuaj rau tshuab; Cov txheej txheem machining ib txwm yog kim, tsis muaj txiaj ntsig, thiab nws yooj yim rau deformation.

Poob- pov tseg 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 qhov xav tau, thiab tom qab ntawd txheej txheej ntawm cov qauv siv quav ciab nrog ntau txheej ntawm cov khoom siv refractory los tsim lub plhaub. Tom qab lub plhaub pwm dries thiab hardens, cov qauv siv quav ciab yog rhuab kom yaj thiab ntws tawm, yog li tsim kom muaj kab noj hniav nrog cov duab zoo ib yam li ib feem. Thaum kawg, cov hlau molten yog poured rau hauv kab noj hniav, thiab tom qab txias thiab solidification, qhov xav tau ib feem yog tau.

1. Pwm tsim thiab tsim khoom

Tsim thiab tsim cov pwm raws li qhov loj, cov duab, thiab cov kev xav tau ntawm cov khoom siv me me. High-txoj kev machining precision, xws li CNC machining, feem ntau yog siv los xyuas kom meej qhov raug thiab qhov zoo ntawm cov pwm. Kev tsim pwm yuav tsum xav txog yam xws li tus nqi shrinkage ntawm tus qauv siv quav ciab thiab txoj kev demolding.

2. Kev xaiv thiab kho cov khoom siv quav ciab

Xaiv cov khoom siv quav ciab uas tsim nyog, feem ntau yuav tsum tau muaj dej zoo, qis qis, thiab lub zog nruab nrab. Cov ntaub ntawv siv quav ciab feem ntau suav nrog paraffin -stearic acid-raws li waxes. Ua ntej siv, cov khoom siv quav ciab yuav tsum tau yaj thiab lim kom tshem tawm impurities thiab cua npuas.

3. Ciab qauv nias

Txhaj cov khoom siv quav ciab rau hauv pwm, thiab nyob rau hauv qee qhov siab thiab kub, sau cov kab noj hniav nrog cov khoom siv quav ciab. Thaum lub sij hawm nias, lub siab, qhov kub thiab txias, thiab lub sij hawm tuav yuav tsum tau ua tib zoo tswj kom ntseeg tau tias qhov tseeb qhov tseeb thiab qhov chaw zoo ntawm cov qauv siv quav ciab. Tom qab nias, tus qauv siv quav ciab txias thiab demolded kom tau txais cov qauv siv quav ciab zaum kawg.

1. Txheej: Muab cov qauv siv quav ciab rau hauv cov txheej txheem, kom ntseeg tau tias muaj txheej txheej txheej ntawm nws qhov chaw. Cov txheej txheej feem ntau muaj cov ntaub ntawv refractory (xws li silica sol, zircon hmoov, thiab lwm yam), binders, thiab additives. Lub viscosity, ntom, thiab txheej thickness ntawm cov txheej yuav tsum tau ua tib zoo tswj thaum lub sij hawm txheej txheej txheem los lav qhov zoo ntawm lub plhaub.

2. Sanding: Tam sim ntawd tom qab txheej, tso cov qauv siv quav ciab rau hauv lub thawv xuab zeb thiab nphoo ib txheej ntawm cov xuab zeb refractory. Qhov loj me me thiab cov khoom siv ntawm cov xuab zeb yuav tsum raug xaiv raws li qhov xav tau ntawm lub plhaub. Lub hom phiaj ntawm sanding yog ua kom lub zog thiab permeability ntawm lub plhaub.

3. Qhuav thiab Hardening: Tom qab txheej thiab xuab zeb, tso cov qauv siv quav ciab rau hauv chav ziab kom qhuav thiab tawv. Kub, av noo, thiab lub sij hawm yuav tsum tau ua tib zoo tswj thaum ziab thiab hardening kom ntseeg tau lub zog thiab permeability ntawm lub plhaub. Feem ntau, cov kauj ruam ntawm txheej txheej, xuab zeb, ziab, thiab hardening yuav tsum tau rov ua ntau zaus kom txog thaum lub plhaub ncav cuag lub thickness thiab lub zog.

4. Dewaxing: Lub plhaub pwm yog rhuab mus rau qhov kub thiab txias, ua rau cov qauv siv quav ciab yaj thiab ntws tawm. Txoj kev dewaxing muaj xws li dej kub dewaxing thiab chav dewaxing. Kub thiab lub sij hawm yuav tsum tau ua tib zoo tswj thaum lub sij hawm dewaxing kom tiav melting thiab ntws ntawm tus qauv siv quav ciab thaum tiv thaiv cov pwm plhaub los ntawm cracking.

1. Titanium Alloy Melting: Titanium alloy raw cov ntaub ntawv yog melted siv txoj kev xws li nqus induction melting. Kev tswj nruj ntawm melting kub, lub sij hawm, thiab cua yog qhov tseem ceeb thaum lub sij hawm melting kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab zoo ntawm titanium alloy.

2. Casting: Lub molten titanium alloy yog poured rau hauv lub preheated pwm plhaub. Pouring kub, ceev, thiab siab yuav tsum tau ua tib zoo tswj thaum lub sij hawm casting los xyuas kom meej lub molten titanium alloy nyob rau hauv pwm kab noj hniav thiab tiv thaiv tsis xws luag xws li porosity thiab inclusions.

1. Tshem tawm plhaub: Tom qab casting, titanium alloy yog txias thiab solidified, thiab lub plhaub pwm raug tshem tawm. Cov txheej txheem tshem tawm plhaub muaj xws li kev tshem tawm cov tshuab thiab tshuaj lom neeg lub plhaub.

2. Kev kho cua sov: Lub me me module zog tom qab tshem tawm lub plhaub tau txais kev kho cua sov los txhim kho lawv cov microstructure thiab cov khoom. Cov kev kho cua sov feem ntau muaj xws li annealing, quenching, thiab tempering.

3. Machining thiab Surface Treatment

Raws li cov iav qhov yuav tsum tau ua kom raug, cov cua sov- kho cov iav tau siv cov txheej txheem machining xws li kev sib tsoo thiab honing los txhim kho qhov tseeb qhov tseeb thiab qhov zoo. Tib lub sijhawm, kev kho saum npoo xws li nitriding thiab tawv chrome plating yog siv los txhim kho hnav tsis kam thiab corrosion kuj.

1. High Precision: Poob- wafer casting tuaj yeem tsim me me - qauv iav nrog qhov siab qhov tseeb thiab cov duab nyuaj, ua tau raws li qhov yuav tsum tau ua ntawm precision machinery thiab instrumentation.

2. Kev siv cov khoom siv siab: Muab piv rau cov txheej txheem machining ib txwm, poob -wafer casting txo cov khoom pov tseg thiab txhim kho kev siv cov khoom.
