1. Tig thiab tho txawv ntawm titanium alloys
Cov teeb meem tseem ceeb ntawm kev tig titanium alloys yog: kub txiav; hnav cov cuab yeej hnyav; loj txiav rebound. raws li kev ua haujlwm tsim nyog. Thiab tsis tig los yog tho txawv yog cov haujlwm nyuaj tshwj xeeb. Rau kev txiav tsis tu ncua, kev tsim khoom loj lossis siab ntim hlau tshem tawm, cov cuab yeej carbide feem ntau siv. Thaum txiav, tig los yog txiav, nws yog qhov tsim nyog los kho cov cuab yeej steel, kuj siv cov cuab yeej cermet. Zoo li lwm yam kev ua haujlwm machining, cov khoom siv dag zog tas li yog ib txwm siv kom tsis txhob muaj kev cuam tshuam hauv kev txiav. Tsis txhob nres lossis qeeb thaum txiav. Feem ntau, tsis txhob txiav nws, thiab nws yuav tsum tau txias tag nrho; lub coolant tuaj yeem yog 5 feem pua sodium nitrate aqueous tov los yog 1/20 soluble roj emulsion aqueous kua. Ua ntej forging, txheej txheej oxygen-enriched rau saum npoo ntawm raw bar yuav tsum tig nrog cov cuab yeej cemented carbide. Qhov tob txiav yuav tsum ntau dua li cov thickness ntawm cov pa oxygen-enriched txheej. Kev txiav ceev yog 20 ~ 30m / min, tus nqi pub yog 0.1 ~ 0.2mm / r, Lub qhov yog finely machined, tshwj xeeb tshaj yog rau nyias-walled titanium khoom. Hlawv thiab clamping deformation ntawm qhov chaw yuav tsum tau tiv thaiv thaum drilling.
2. Drilling ntawm titanium alloys
titanium alloys yog feem ntau ua rau slender thiab curled chips thaum drilling, thiab nyob rau tib lub sij hawm, lub siab drilling cua sov ua rau cov chips kom ntau dhau los yog lo rau ntawm ntug ntawm lub qhov, uas yog lub ntsiab yog vim li cas rau qhov nyuaj ntawm drilling titanium alloys. Drilling yuav tsum tau ua nrog ib tug luv luv, ntse xyaum me ntsis thiab ib tug tsawg-ceev quab yuam pub, thiab kev txhawb nqa ncej yuav tsum tau nruj nreem dua thiab txias txaus, tshwj xeeb tshaj yog rau qhov tob qhov drilling. Thaum lub sij hawm drilling txheej txheem, lub laum me ntsis yuav tsum tau khaws cia nyob rau hauv lub xeev drilling nyob rau hauv lub qhov, idling nyob rau hauv lub qhov yog tsis tso cai, thiab qhov drilling ceev yuav tsum tau ceev thiab tsis tu ncua. Laum qhov ua tib zoo. Thaum drilling yog yuav tsum tau drilled, nws yog qhov zoo tshaj plaws kom tshem tawm cov laum kom huv si laum, laum qhov thiab tshem tawm cov chips. Thaum lub qhov kawg tawg lawm, yuam kev pub mis yuav siv tau kom tau ib lub qhov du.
3. Coj mus rhaub Titanium
Tapping ntawm titanium alloys yog tej zaum cov txheej txheem nyuaj tshaj plaws. Thaum tapping, tshem tawm ntawm titanium shavings yog txwv, thiab ib qho kev nyiam heev rau tom tuaj yeem ua rau cov xov tsis zoo, uas tuaj yeem ua rau kais qaug lossis tawg. Titanium alloys zoo li qhuav zawm ntawm tus kais dej tom qab tapping. Yog li ntawd, qhov qhov muag tsis pom los yog ntev dhau los ntawm qhov yuav tsum tau zam kom ntau li ntau tau los tiv thaiv qhov roughness ntawm cov xov sab hauv los ntawm qhov loj los yog qhov tshwm sim ntawm taper tawg. Nyob rau tib lub sijhawm, tapping txoj kev yuav tsum tau txhim kho tas li, xws li kev sib tsoo ntawm ntug ntawm tus kais dej. Axial nti flutes yog hauv av ntawm tus hniav ntsis raws li qhov ntev ntawm tus hniav flank. Ntawm qhov tod tes, cov kais dej nrog oxidized, oxidized los yog chromed nto yog siv los txo qhov qaug dab peg thiab hnav.
4. Sawing ntawm titanium alloys
Thaum sawing titanium alloys, yuav tsum tau siv qhov chaw qis qis thiab kev quab yuam tsis tu ncua. Cov kev sim tau pom tias cov ntxhib-toothed high-speed steel saw hniav nrog lub suab ntawm 4.2 hli txog 8.5 hli yog tsim rau sawing titanium alloys. Yog tias siv band pom titanium alloy, cov saw hniav pitch yog txiav txim siab los ntawm qhov tuab ntawm lub workpiece, feem ntau 2.5 hli ~ 25.4 hli, cov khoom tuab dua, lub suab loj dua. Nyob rau tib lub sijhawm, qhov yuam kev muaj peev xwm thiab cov dej txias yuav tsum tau tswj xyuas.
5. EDM ntawm titanium
EDM ntawm titanium alloys yuav tsum muaj kev khiav hauj lwm clearance ntawm lub cuab tam thiab lub workpiece. Qhov ntau ntawm qhov sib txawv yog qhov zoo dua {{0}}.005mm ± 0.4mm. Cov qhov khoob me me feem ntau yog siv rau kev ua tiav cov haujlwm uas yuav tsum tau ua kom du, thaum qhov khoob loj dua yog siv rau kev ua haujlwm roughing uas yuav tsum tau tshem tawm cov hlau sai. Tooj thiab zinc yog cov khoom siv electrode zoo tshaj plaws.
