Xauv Lub tog raj kheej Rotor Titanium Alloy Poob -wax Casting

o High Strength: Titanium alloys have strength similar to alloy steel, but a much lower density, allowing for weight reduction while maintaining sufficient strength in the lock cylinder rotor. Qhov no yog qhov tseem ceeb rau cov xauv tshwj xeeb nrog qhov hnyav txwv, xws li cov siv hauv aviation.

o Corrosion Resistance: A dense oxide film forms on the surface of titanium alloys. Cov oxide zaj duab xis no muaj kev ruaj ntseg zoo heev, tiv thaiv corrosion los ntawm ntau yam xov xwm, suav nrog huab cua ntub thiab dej hiav txwv. Qhov no txhais tau hais tias lub xauv lub tog raj kheej rotors ua los ntawm titanium alloys tuaj yeem siv tau rau lub sijhawm ntev hauv qhov chaw hnyav yam tsis muaj corrosion, ncua lub xauv lub neej.

o Biocompatibility: Thaum biocompatibility tsis yog ib qho tseem ceeb ntawm cov xauv zoo tib yam, hauv qee qhov kev siv tshwj xeeb, xws li cov xauv rau cov khoom siv kho mob, biocompatibility ntawm titanium alloys tuaj yeem tiv thaiv kev tsis zoo rau tib neeg lub cev.

o Kev Xaiv Cov Txheej Txheem: Raws li cov kev xav tau tshwj xeeb thiab kev ua tau zoo ntawm lub tog raj kheej lub tog raj kheej rotor, xaiv qhov tsim nyog titanium alloy muaj pes tsawg leeg. Feem ntau titanium alloys suav nrog Ti-6Al-4V, qhov twg txhuas (Al) txhim kho lub zog thiab thermal stability ntawm titanium alloy, thaum vanadium (V) pab txhim kho cov alloy lub machinability thiab toughness.

* Pwm Tsim: Raws li peb qhov - qauv qauv ntawm lub xauv lub tog raj kheej rotor, pwm rau ua cov qauv siv quav ciab yog tsim thiab tsim. Qhov tseeb ntawm cov pwm ncaj qha cuam tshuam rau qhov tseeb qhov tseeb ntawm cov qauv siv quav ciab; yog li ntawd, siab - cov cuab yeej machining thiab cov txheej txheem yuav tsum tau ua los tsim cov pwm.

* Wax Model Forming: Molten wax yog txhaj rau hauv pwm. Tom qab cov quav ciab txias thiab solidifies, tus qauv siv quav ciab raug tshem tawm ntawm pwm. Txhawm rau kom ntseeg tau qhov zoo ntawm cov qauv siv quav ciab, cov txheej txheem tsis xws li siv quav ciab kub, kev txhaj tshuaj siab, thiab tus nqi txias yuav tsum tau tswj.

* Wax Model Assembly: Ib tus qauv siv quav ciab tau sib sau ua ke rau hauv cov qauv siv quav ciab los ntawm kev sib txuas los yog kev sib txuas los pab txhawb kev ua haujlwm tom ntej. Thaum lub sij hawm sib dhos, nws yog ib qho tseem ceeb los xyuas kom meej kev ruaj ntseg kev sib txuas thiab qhov tseeb qhov chaw ntawm cov qauv siv quav ciab.

* Kev Siv Slurry: Cov qauv siv quav ciab tau muab tso rau hauv cov slurry uas muaj cov ntaub ntawv refractory, binders, thiab additives, kom ntseeg tau tias cov txheej txheem ntawm slurry nyob rau saum npoo. Ib txheej ntawm cov xuab zeb refractory yog ces sprinkled mus rau slurry nto kom ntseeg tau ruaj khov.

* Qhuav thiab Hardening: Cov qauv siv quav ciab coated nrog slurry thiab refractory xuab zeb undergoes ziab thiab hardening kho. Qhov no tso cai rau lub binder nyob rau hauv lub slurry rau reacts chemically, tsim ib tug robust plhaub. Lub sijhawm ziab thiab tawv tawv thiab qhov ntsuas kub yuav tsum tau ua tib zoo tswj raws li slurry muaj pes tsawg leeg thiab ib puag ncig.

* Rov ua txheej txheej: Txhawm rau kom lub zog thiab tuab ntawm lub plhaub, cov txheej txheem slurry thiab xuab zeb txheej yog rov ua dua, feem ntau xav tau 3-5 txheej. Txhua txheej yuav tsum tau qhuav thiab hardened tom qab thov.

* Dewaxing: Lub plhaub pwm npaj tau muab tso rau hauv lub tshuab dewaxing. Cov cua sov melts tus qauv siv quav ciab, ua rau nws ntws tawm ntawm lub plhaub pwm, yog li tsim cov kab noj hniav hauv lub plhaub pwm uas phim cov duab ntawm lub xauv core rotor. Thaum lub sij hawm dewaxing, cov cua kub kub thiab lub sij hawm yuav tsum tau ua tib zoo tswj los tiv thaiv lub puab plhaub los ntawm cracking.

* Titanium Alloy Melting: titanium alloy raw khoom yog muab tso rau hauv lub tshuab nqus tsev induction rauv rau melting. Thaum lub sij hawm melting, tsis xws li lub tshuab nqus tsev, kub, thiab lub sij hawm melting yuav tsum nruj me ntsis tswj kom lub uniformity thiab purity ntawm titanium alloy muaj pes tsawg leeg.

* Casting: Thaum cov titanium alloy tau mus txog qhov ntsuas kub thiab muaj pes tsawg leeg, nws tau nrawm nrawm rau hauv lub plhaub pwm preheated. Thaum lub sij hawm casting, yuav tsum tau them nyiaj mloog mus rau lub pouring ceev thiab txoj kev kom tsis txhob muaj qhov tsis xws luag xws li porosity thiab inclusions.

* Pwm Plhaub Ntxuav: Tom qab lub casting tau txias lawm, lub plhaub pwm raug tshem tawm siv txoj kev xws li kev vibration thiab sandblasting.

* Kev kho cua sov: Lub kaw lus tseem ceeb rotor tau kho cua sov los txhim kho nws cov microstructure thiab cov khoom. Cov txheej txheem kev kho cua sov feem ntau muaj xws li annealing, quenching, thiab tempering. Cov kev kho cua sov tshwj xeeb yuav tsum tau txiav txim siab raws li titanium alloy muaj pes tsawg leeg thiab daim ntawv thov kev xav tau ntawm lub xauv lub tog raj kheej rotor.

* Machining thiab Surface Treatment: Raws li cov qauv tsim ntawm lub tog raj kheej rotor, nws yog machined, xws li los ntawm drilling thiab milling, kom ua tiav qhov ntev thiab qhov roughness. Thaum kawg, lub xauv lub tog raj kheej rotor raug kho saum npoo, xws li electroplating thiab txau, txhawm rau txhim kho nws cov hnav tsis kam thiab corrosion kuj.
