Muaj Zog Tshwj Xeeb Siab
Qhov piv ntawm lub zog tensile (≥895 MPa) rau qhov ceev yog siab dua li ntawm cov hlau tsis xeb thiab txhuas alloy, ua rau nws tsim nyog rau cov ntawv thov uas muaj qhov hnyav (xws li cov qauv dav hlau thiab cov khoom drone).
Tom qab kev kho mob laus ntawm cov tshuaj
Los ntawm kev kho cua sov
Los ntawm kev kho cua sov (xws li β annealing + kev laus), lub zog tensile tuaj yeem nce ntxiv mus rau 1000 ~ 1100 MPa, tab sis qhov elongation txo qis me ntsis (6% ~ 10%).
Lub zog qaug zog
Kev ua tau zoo heev nyob rau hauv kev thauj khoom cyclic, tshwj xeeb tshaj yog haum rau cov chaw vibrating xws li cov khoom siv cav.
Titanium Hex Head Bolts (screws) qhov zoo ntawm cov qauv
Kev Teeb Tsa Yooj Yim
Lub taub hau hexagonal sib xws nrog cov cuab yeej xws li wrenches thiab screwdrivers, muab thaj chaw sib cuag loj dua thiab kev sib kis torque zoo rau kev nruj lossis rhuav tshem sai.
Tsim Kev Tiv Thaiv Kev Ywj Pheej
Thaum siv nrog cov txiv ntoo tiv thaiv kev xoob, cov ntaub txuas lossis cov kua nplaum xov, nws tuaj yeem ua kom qhov kev sib txuas ruaj khov hauv qhov chaw co (xws li tsheb thiab tshuab) thiab txo qhov kev pheej hmoo ntawm kev xoob.
Kev sib xyaw ua ke zoo meej ntawm lub zog siab thiab lub teeb yuag
Titanium hexagonal bolts muaj qhov ceev tsuas yog ib nrab ntawm cov hlau, tab sis muaj lub zog siab heev. Piv txwv li, TC4 titanium alloy uas siv dav dav muaj lub zog tensile ntau dua 900MPa. Hauv kev lag luam aerospace, titanium hexagonal bolts siv los txuas lub fuselage ntawm lub dav hlau. Thaum ua kom ntseeg tau tias lub zog ntawm lub dav hlau ua tau raws li qhov yuav tsum tau ua ntawm kev ya dav hlau, nws txo qhov hnyav ntawm lub fuselage, yog li ua kom roj siv tau zoo dua thiab txo cov nqi khiav lag luam. Hauv kev tsim tsheb, lub cav ncua kev siv titanium hexagonal bolts, uas tsis yog tsuas yog txo qhov hnyav ntawm cov khoom thiab pab lub tsheb ua tiav kev ua haujlwm zoo dua, tab sis kuj txo kev siv zog, uas yog nyob rau hauv kab nrog kev txhim kho tam sim no ntawm kev mus ncig ntsuab.
Kev tiv thaiv xeb zoo heev
Cov khoom siv tshuaj lom neeg ntawm titanium ua rau nws yooj yim heev los tsim cov zaj duab xis oxide ruaj khov heev ntawm nws qhov chaw.
