Titanium alloy electrolytic machining txheej txheem
Qhov ceev ntawm titanium alloys feem ntau yog nyob ib ncig ntawm 4.51g / cm3, uas tsuas yog 60% ntawm cov hlau. Lub zog ntawm ntshiab titanium tsuas yog ze rau lub zog ntawm cov hlau zoo tib yam. Qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov qauv hlau alloy. Yog li ntawd, lub zog tshwj xeeb (lub zog / qhov ntom) ntawm titanium alloy yog ntau dua li ntawm lwm cov khoom siv hlau, thiab cov khoom thiab cov khoom siv nrog lub zog siab, zoo rigidity, thiab lub teeb yuag tuaj yeem tsim tau. Tam sim no, titanium alloys yog siv nyob rau hauv aircraft engine Cheebtsam, ncej, tawv, fasteners thiab tsaws iav. Txij li cov txheej txheem electrolytic muaj qhov zoo ntawm lub sijhawm luv luv thiab kev ua haujlwm siab, nws feem ntau tsis txwv los ntawm hom kev ua cov khoom siv. Yog li ntawd, nws tuaj yeem siv los ua cov txheej txheem zoo tshaj plaws rau kev ua cov ntaub ntawv titanium alloy. Kab lus no muab cov txheej txheem tsim khoom tiag tiag los qhia txog kev siv cov txheej txheem electrolytic li cas. Kev ua cov khoom siv titanium alloy.
Tshawb nrhiav cov ntsiab lus thiab kev daws teeb meem
1. Tsim thiab tsim cov cathodes
Txij li qhov loj ntawm cov khoom ua tiav yuav tsum yog me me thiab cov duab yog qhov nyuaj, thiab qhov sib txawv ntawm cov electrode thiab qhov sib xws ntawm electrolysis flow field yuav tsum tau txiav txim siab, qhov tsis zoo ntawm cov electrode yuav tsum tau tshawb xyuas los ntawm kev sim electrolysis. nyob rau hauv cov nqe lus ntawm kev tsim thiab kev tsim khoom. Qhov tseeb electrode yog qhia hauv daim duab 1:
2. Kev ua haujlwm clearance
Thaum lub sij hawm electrochemical machining, qhov sib txawv me me, qhov zoo ntawm qhov zoo, thiab qhov siab dua qhov tseeb ntawm machining. Thaum lub sij hawm electrochemical machining, lub cathode khaws cia thiab cov anode tseem yaj. Thaum lub sij hawm electrochemical machining txheej txheem, machining voltage thiab pub ceev muaj ib qho tseem ceeb cuam tshuam rau lub machined nto zoo thiab machining raug, yog li nws yog tsim nyog los kawm txog qhov sib txawv. Thawj qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv muaj cov hauv qab no electrochemical machining kev sib raug zoo: Los ntawm cov saum toj no, nws tuaj yeem pom tau tias los ntawm kev kho qhov voltage, pub ceev thiab xaiv cov electrolyte tsim nyog, qhov sib txawv machining tuaj yeem tswj tau zoo.
3. Kev xaiv cov txheej txheem electrolyte
NaCl yog lub zog electrolyte uas yuav luag tag nrho ionize rau hauv Na + thiab Cl-ions hauv cov kua dej, thiab tuaj yeem ua ke nrog H + thiab OH- ntshav hauv dej. Hauv kev xav, NaCl electrolyte tuaj yeem ua tiav los ntawm kev hloov kho kom tsim nyog thaum ua cov titanium alloy daim hlau. Voltage, pub ceev thiab optimized electrode qauv yuav ua rau zoo dua nto zoo thiab ntau dua precision ntawm cov khoom tiav. Thaum siv NaCl ua cov kua dej electrolyte, nws cov concentration feem ntau tswj tau ntawm 10%-14%. Thaum qhov kev xav tau ntawm qhov chaw zoo siab, nws feem ntau tswj tau qis dua 10%. Kev ua haujlwm kub yog feem ntau tswj ntawm 14% concentration. NaCl tov tau siv los ua cov electrolyte hauv txoj kev tshawb no. Nyob rau tib lub sijhawm, txhawm rau xyuas kom muaj txiaj ntsig zoo ntawm kev siv electrolyte.
4. Rwb thaiv tsev cais ntawm qhov chaw tsis ua haujlwm
Thaum lub sij hawm electrolytic machining txheej txheem, txhawm rau tiv thaiv qee qhov tsis ua tiav los ntawm pitting corrosion, qee qhov kev tiv thaiv kev tiv thaiv feem ntau yog siv. Tom qab kev xyaum, nws tau txiav txim siab thaum kawg tias txoj kev siv tshuaj tua hluav taws xob tsis tuaj yeem tsuas yog tiv thaiv cov electrolyte los ntawm kev tiv thaiv qhov tsis ua tiav, tab sis kuj ua lub luag haujlwm hauv kev cais cov stray tam sim no. Cov non-metallic insulating txheej sprayed yog thinner thiab kev sib txuas yog txhim khu kev qha. Nws yuav tsis yaj los yog poob vim qhov kub thiab txias tsim los ntawm electrolysis, thiab tuaj yeem siv ntau zaus tom qab ib qho tshuaj tsuag.
Tom qab ua tiav cov kev xaiv ntawm cov electrolyte, kev txiav txim siab ntawm kev ua tsis tau, txau ntawm cov rwb thaiv tsev tiv thaiv txheej, thiab lwm yam, ua ke nrog qhov tsim nyog indexing fixtures, kev hloov kho thiab kev sib dhos thiab lwm yam kev npaj ua ntej, cov khoom raug ua tiav, thiab cov khoom siv tiag tiag yog ua tiav. Cov nyhuv yog pom nyob rau hauv daim duab 2. Tom qab kev soj ntsuam, qhov tseeb ua qhov ntev tuaj yeem ua tau raws li qhov tseeb thiab qhov loj me uas yuav tsum tau ua los ntawm tus qauv tsim. Piv nrog rau cov txheej txheem EDM, nws cov kev ua tau zoo yog nce ntau dua 95%, uas tsis yog tsuas yog txhim kho kev tsim khoom, tab sis kuj txuag cov nqi tsim khoom, ntau tus neeg ua haujlwm thiab cov khoom siv, thiab zam cov khoom siv pov tseg uas tsis tsim nyog. Thaum electrochemical ua ntawm titanium alloy cov khoom, ntev li ntev raws li cov txheej txheem electrode raug tsim, cov txheej txheem ua tau raug xaiv tsim nyog, cov txheej txheem electrolyte tau npaj kom raug, thiab cov txheej txheem kev tiv thaiv zoo tshaj plaws raug saws, cov khoom uas ua tau raws li cov qauv tsim tuaj yeem ua tiav zoo. thiab nyob rau hauv ib lub sij hawm luv luv ntawm ib lub sij hawm.
