Nyob rau hauv precision Cheebtsam rau aerospace thiab siab -kawg cov cuab yeej kho mob,Ti-6Al-4V titanium alloytau dhau los ua cov khoom tseem ceeb irreplaceable vim nws lub zog siab, hnav, thiab zoo heev corrosion kuj. Txawm li cas los xij, "tus huab tais kev ua tau zoo" nthuav tawm cov teeb meem tseem ceeb thaum khoov; txawm tias me ntsis yuam kev tuaj yeem ua rau tawg, springback, thiab lwm yam teeb meem, cuam tshuam rau cov khoom zoo. Niaj hnub no, peb yuav rhuav tshem cov ntsiab lus tseem ceeb rau kev ua Ti-6Al-4V titanium alloy khoov qhov chaw los pab koj kom kov yeej cov txheej txheem nyuaj no!
1. Preheating thiab Temperature Control
Ua kom muaj kev nyab xeeb ua kab. Ti-6Al-4V titanium alloy muaj cov yas tsis zoo nyob rau hauv chav tsev kub, thiab qhov kub thiab txias qis tuaj yeem ua rau tawg yooj yim. Yog li ntawd, lub workpiece yuav tsum tau preheated ua ntej ua. Lub preheating kub yuav tsum nruj me ntsis tswj ntawm 200-400 degree. Qhov ntsuas kub no tuaj yeem txhim kho cov khoom siv plasticity thiab tsim kom muaj txiaj ntsig zoo rau kev khoov.
Nyob rau tib lub sijhawm, qhov kev pheej hmoo ntawm overheating hauv zos yuav tsum raug sau tseg. Thaum qhov kub siab tshaj 500 degree, cov nplej ntawm Ti-6Al-4V titanium alloy yuav coarsen sai, ua rau muaj kev txo qis hauv cov khoom siv kho tshuab. Nws raug nquahu kom siv lub ntsuas kub infrared los saib xyuas qhov ntsuas kub ntawm lub sijhawm ua haujlwm kom ntseeg tau tias cov cua sov tsis sib xws thiab raug, yog li tiv thaiv cov teeb meem zoo los ntawm qhov pib.
2. dabtsi yog khoov tus nqi thiab siab: Tsawg-ceev precision, scientific nyiaj them
Vim yog hom kab mob -kev laus tus yam ntxwv ntawm Ti-6Al-4V titanium alloy, nrawm nrawm tuaj yeem ua rau muaj kev ntxhov siab. Yog li ntawd, txoj kev khoov yuav tsum tau nqa tawm ntawm qhov ceev ceev, nyiam dua tsawg dua lossis sib npaug li 5mm / s. Kev ua haujlwm du tuaj yeem txo qis kev ntxhov siab thiab tsis txhob ua haujlwm puas tsuaj.
Kev txiav txim siab dabtsi yog khoov yuav tsum tau sim khoov kom pom qhov zoo tshaj plaws: lub siab me me yuav ua rau lub cev muaj zog hnyav, thiab lub caij nplooj ntoos hlav ntawm Ti-6Al-4V titanium alloy yog siab dua li cov hlau zoo tib yam, yog li 10% -15% nyiaj pub dawb yuav tsum tau tshwj tseg; Lub siab ntau dhau tuaj yeem ua rau wrinkling thiab tawg ntawm qhov khoov, cuam tshuam ncaj qha rau cov khoom tsim nyog tus nqi.
3. Pwm thiab Lubrication: Kev sib txuam kom zoo txo kev sib txhuam
Qhov zoo ntawm qhov tuag ncaj qha txiav txim siab qhov kev khoov qhov tseeb. Muab lub siab tawv ntawm TC4 titanium alloy, tuag ua los ntawm siab - cov ntaub ntawv muaj zog xws li H13 kub ua haujlwm tuag steel yuav tsum raug xaiv. Lawv zoo heev hnav tsis kam thiab thermal stability zoo tiv taus hnav thaum ua, kom ntseeg tau ruaj khov kho qhov tseeb. Tsis tas li ntawd, lub siab -kub, molybdenum- cov roj nplua nyeem yuav tsum tau siv rau thaj tsam ntawm qhov chaw ua haujlwm thiab tuag ua ntej khoov. Qhov kev ua haujlwm no tsis yog tsuas yog txo qis kev sib txhuam thiab tiv thaiv khawb ntawm qhov chaw ua haujlwm tab sis tseem tiv thaiv cov tuag los ntawm kev ua raws li cov khoom ua haujlwm, ua rau cov txheej txheem khoov smoother.
4. Kev ua haujlwm tom qab thiab kev tshuaj xyuas zoo: Ntau txheej txheej ntawm cov tshev kom ntseeg tau zoo
Tom qab khoov, residual internal stress yuav nyob twj ywm nyob rau hauv lub workpiece. Yog tias tsis tshem tawm hauv lub sijhawm, deformation yuav tshwm sim thaum siv tom ntej. Kev ntxhov siab -relief annealing yog qhov tsim nyog rau qhov no. Lub workpiece yog tuav ntawm 550-600℃rau 1-2 teev kom tso tawm tag nrho cov kev ntxhov siab sab hauv thiab xyuas kom meej cov khoom seem stability.
Kev tshuaj xyuas zoo yog qhov tseem ceeb kawg ntawm kev tiv thaiv, yuav tsum tau tsom xyuas qhov tseeb ntawm peb yam:
1. Bending lub siab kam rau ua: nruj me ntsis raws li tus qauv, tswj kev kam rau siab nyob rau hauv ± 1℃kom paub meej kev sib dhos;
2. Qhov chaw tsis xws luag: Ua tib zoo tshuaj xyuas cov kab nrib pleb, dents, thiab lwm yam teeb meem kom tsis txhob cuam tshuam cov khoom muag thiab kev ua neej;
3. Cov khoom siv tshuab: Ntsuas lub zog tensile ntawm qhov taw tes dabtsi yog khoov, kom ntseeg tau tias tsawg kawg 90% ntawm cov khoom siv lub hauv paus yog khaws cia kom ntseeg tau tias cov khoom tuaj yeem tiv taus qhov chaw ua haujlwm nyuaj.
