Sib sib zog nqus nqus formability ntawm titanium alloy daim hlau
Sib sib zog nqus nqus formability ntawm titanium alloy daim hlau
Titanium alloy daim ntawv muaj qee yam khoom tshwj xeeb thiab cov nyom thaum nws los txog rau kev kos duab sib sib zog nqus. Cov hauv qab no yog qee qhov tseem ceeb hais txog qhov sib sib zog nqus kos formability ntawm titanium alloy nplooj ntawv:
Siab zog thiab tsis tshua muaj plasticity: Titanium alloy muaj lub zog siab thiab tsis tshua muaj plasticity, uas yuav tsum tau muaj zog ntau dua thaum lub sij hawm tsim. Qhov no tej zaum yuav xav tau cov cuab yeej muaj zog dua thiab cov txheej txheem tsim ntau dua.
High Hardness: Titanium alloys feem ntau nyuaj dua li qee cov hlau xws li hlau lossis txhuas. Qhov no tuaj yeem ua rau hnav thiab tsim kua muag thaum lub sij hawm tsim cov txheej txheem, yuav tsum tau siv cov cuab yeej hnav-resistant ntau dua.
Kub rhiab heev: Titanium alloys kuj rhiab heev rau kub hloov. Thaum lub sij hawm sib sib zog nqus nqus cov txheej txheem, qhov kub thiab txias yuav tsum tau tswj kom ntseeg tau tias tsim kom haum. Qhov kub thiab txias yuav ua rau cov khoom muag muag heev, thaum qhov kub thiab txias yuav ua rau kev sib sau nyuaj dua.
Oxidation teeb meem: Titanium alloys yooj yim hnov mob nrog oxygen ntawm qhov kub thiab txias los tsim oxides. Qhov no tuaj yeem ua rau txo qis hauv qhov zoo thiab xav tau kev ntsuas los tiv thaiv oxidation, xws li kev siv cov cua tiv thaiv thaum lub sij hawm tsim cov txheej txheem.
Kev tsim cov txheej txheem optimization: Vim muaj cov khoom tshwj xeeb ntawm titanium alloys, cov txheej txheem tsim yuav tsum tau ua kom zoo. Qhov no tej zaum yuav muaj xws li cov lubricants tsim nyog, ua kom ceev, tswj qhov kub thiab txias thiab kev kho rau cov txheej txheem tsis.
Hlau Flow: Titanium alloys muaj cov hlau tsis zoo, uas tuaj yeem ua rau cov kab nrib pleb lossis wrinkles thaum lub sij hawm tsim. Yog li ntawd, ua tib zoo tsim pwm thiab kev xaiv tsim nyog ntawm kev sib sau ua ke yuav tsum tau ua kom zoo hlau ntws.
Feem ntau siv sib sib zog nqus kos duab ntawm titanium daim hlau thiab titanium rods
Cov txheej txheem deformation ntawm titanium daim hlau kuj tseem tuaj yeem muab sau ua cov duab sib sib zog nqus, auxetic expansion, flanging, khoov thiab sib sau ua ke. Txawm li cas los xij, yog siv ib txoj kev sib sib zog nqus deformation, nws yog qhov nyuaj los tsim ib qho qauv. Yog li ntawd, txoj kev sib xyaw deformation tau siv tiag tiag hauv kev sim. Tsis tas li ntawd, qhov kev ntsuam xyuas yuav ua rau muaj kev cuam tshuam ntawm cov qauv pwm thiab cov txheej txheem kev ua haujlwm, yog li kev ntsuam xyuas ntawm daim ntawv kos duab kev ua tau zoo yog qhov teeb meem nyuaj. Kev tshawb fawb ua hauj lwm ntawm lub teb chaws kem-zoo li tus titanium rods mas siv qhov txwv tsis pub kos coefficient K (LDR) ua ib qho qhia. Ntau yam kev ntsuam xyuas tau raug npaj los ntawm ntau qhov kev xav xws li kev tshuaj xyuas, kev tshuaj xyuas, thiab kev txheeb cais, thiab ntau yam teeb meem tau daws. Txawm li cas los xij, lawv feem ntau yog siv rau hauv cov khoom siv hlau thiab txhuas, yog li lawv yuav tsum tau hloov kho thiab ntxiv ua ntej lawv tuaj yeem siv rau hauv titanium thiab titanium alloys. Cov txheej txheem rub tawm rau cylindrical qhov chaw tau thov los ntawm Swift hauv xyoo 1940, siv cov ntaub plaub maj mam nce ntxiv los ntsuas qhov kawg rub tawm coefficient K tus nqi. Pom zoo raws li tus qauv thoob ntiaj teb los ntawm International Drawing Research Society hauv 1967, ntau yam tau kawm los ntawm txoj kev no. Sib sib zog nqus kev ua tau zoo ntawm steel, aluminium, tooj liab thiab lwm daim hlau.
Thaum siv titanium, tshwj xeeb tshaj yog thiab titanium alloys, cov teeb meem tseem ceeb hauv qab no muaj:
A. Khoov kab nrib pleb yuav tshwm sim ntawm plaub fab ntawm lub punch; b. Wrinkles thiab kab nrib pleb yuav tshwm nyob rau ntawm lub voj voog ntawm cov pwm.
Qhov no yog vim tsis zoo khoov thiab wrinkle tsis kam ntawm titanium alloys, uas tsis tuaj yeem piav qhia nws qhov kev ua tau zoo sib sib zog nqus. Piv txwv li, kev kos duab ntawm GR5 thiab GR6 boards tsis zoo lossis tsis tuaj yeem kos duab. Nws txoj kev rub tawm yog ntsuas los ntawm kev siv Englhardt lossis qhov siab tshaj plaws rub tawm txoj kev sim. Qhov teeb meem ntawm khoov puas yog exacerbated vim hais tias cov khoom yuav tsum tau nyob ze rau lub punch thiab ces lub rub tawm quab yuam yog ntsuas. Nws raug nquahu kom nthuav dav lub kaum sab xis ntawm cov xuas nrig ntaus, ntsuas kev tiv thaiv wrinkle ntawm lub kaum sab xis ntawm lub concave tuag, thiab siv cov roj nplua nyeem uas muaj cov graphite los ua cov titanium alloy sib sib zog nqus kev ntsuas.
Zuag qhia tag nrho, sib sib zog nqus nqus ntawm titanium alloy daim hlau yuav tsum tau tshwj xeeb tuav thiab txiav txim siab los kov yeej nws cov kev sib tw tshwj xeeb. Hauv kev siv cov tswv yim, feem ntau nws yog qhov tsim nyog los txiav txim siab qhov kev pom zoo ntawm cov txheej txheem los ntawm kev sim thiab kev ua kom zoo.
