Titanium Precision Forging: Yuav Ua Li Cas Tswj Cov Txheej Txheem Tsis Zoo?

Nyob nruab nrab ntawm cov nthwv dej ntawm kev tsim khoom niaj hnub hloov mus rau siab- kawg thiab precision, precision forging thev naus laus zis, tso siab rau nws cov yam ntxwv tseem ceeb ntawm "ze-net shaping", tau dhau los ua cov thev naus laus zis tseem ceeb hauv cov haujlwm tseem ceeb. Los ntawm precisely tswj cov yas deformation ntawm hlau, nws tsis tsuas yog txhim khoTitanium khoomkev ua tau zoo thiab txuag cov nqi peev txheej tab sis tseem tsim cov kev cai nruj rau cov txheej txheem tswj thiab tswj.

 

 

 

1. Precision thiab Surface Quality

Qhov ntev ntev ntawm precision forgings tuaj yeem tswj tau nyob rau hauv ± 0.050.2mm, thiab siab -cov khoom muaj tseeb xws li aero- lub cav tuaj yeem ncav cuag ± 0.02mm; Qhov saum npoo roughness Ra tsawg dua los yog sib npaug rau 1.6μm, thiab cov khoom siv aluminium alloy tuaj yeem qis li Ra 0.8μm, deb tshaj li ib txwm qhib tuag forging thiab zoo tib yam tuag forging. Feem ntau ntawm lawv tsuas yog yuav tsum tau siv me me ntawm kev sib tsoo, kom txo tau cov txheej txheem txiav tom ntej.

 

2. Kev siv peev txheej zoo heev

Precision forging ua tiav nyob ze -net shaping, nrog cov khoom siv ntawm 80%-95%; ib qho -cov khoom siv ntawm cov tsheb sib kis tau raug txo qis, thiab kev siv cov khoom siv ntawm aero-engine blades yog nce piv nrog cov casting, txo cov pov tseg ntawm cov khoom muaj txiaj ntsig zoo.

 

3. Optimized Mechanical Properties

Precision forging precisely tswj cov hlau ntws, ua cov nplej uniformly refined raws txoj kev ntxhov siab thiab tsim cov kab nrib pleb thiab ua tiav cov hlau ntws, zam kev puas tsuaj rau cov qauv nplej los ntawm kev txiav. Lub zog qaug zog ntawm precision forgings yog ntau tshaj 20% siab dua li ntawm cov khoom siv machined, thiab lub neej kev pab cuam yog multiplied; lub zog tensile thiab qaug zog lub neej ntawm precision -forged cav crankshafts, nrog rau lub siab - kub qaug zog lub neej ntawm aerospace turbine disks, yog txhim kho, uas muaj peev xwm stably withstand huab ua hauj lwm tej yam kev mob siab tshaj 1200 degree.

 

4.Qhov zoo tshaj plaws hauv kev ua tau zoo thiab kev tswj tus nqi

Ib zaug -daim voj voog ntawm automated precision forging cov kab ntau lawm tsuas yog ob peb feeb mus rau ob peb feeb, nrog cov txheej txheem tom qab tsawg dua thiab txo cov nqi ua tiav; Txawm hais tias thawj zaug peev hauv pwm yog qhov siab, nws txuag cov ntaub ntawv thiab muaj qhov seem tsawg. Piv txwv li, Nangong Jingqiang lub siab -kub efficiency- tswj precision forging tshuab rau txuas rods txhim kho efficiency; precision forging kuj tuaj yeem ua tiav kev sib sau ua ke, txo cov kev sib txuas ua ke.

 

 

1. Qhov tshwm sim tsis zoo thiab cov khoom siv raw zoo

Tsim kom muaj tag nrho - txheej txheem tswj qhov tsis zoo yuav tsum muaj kev tswj hwm qhov chaw thiab kev tswj xyuas meej ntawm txhua qhov txuas: cov khoom siv raw yog lub hauv paus. Lub tshuab hluav taws xob arc rauv + LF refining + VD lub tshuab nqus tsev degassing txheej txheem tau txais yuav nruj me ntsis tswj cov sulfur thiab phosphorus impurities, txo cov ntsiab lus hydrogen kom tsis pub dhau 2ppm, thiab siv ultrasonic flaw nrhiav kom tshem tawm qhov tsis xws luag xws li pores thiab inclusions, kom ntseeg tau tias cov tshuaj lom neeg muaj pes tsawg leeg fluctuation yog ± 0. kev cais.

2. Txheej txheem Parameter Control

Kev Tswj Kub Kub: Ua raws li cov cua kub cua sov: qeeb cua sov ntawm tsawg dua lossis sib npaug li 100℃/ h hauv qab 600 degree, ces cua sov rau lub hom phiaj ntawm 200-300℃/ h; pib forging ntawm 1150-1200℃los tiv thaiv cov kab nrib pleb, thiab qhov kawg forging tsis qis dua 850℃los tiv thaiv cov pob dawb thiab cov qauv tsis sib xws.

 

Txias: Differentiated treatment according to cross-sections: air cooling for ≤100mm, furnace cooling at ≤50℃/h for >200mm, thiab qhov dej txias / xuab zeb txias rau qhov tshwj xeeb rau ntau dua lossis sib npaug rau 72 teev los tiv thaiv hydrogen-induced tawg.

 

Txheej txheem deformation: Forging ratio Ntau dua los yog sib npaug rau 5: 1, ntau qhov hluav taws kub ntxhov siab thiab kos duab kom tshem tawm cov xoob xoob; ntxhib forging deformation tus nqi ntawm 5-10% / min thiab precision forging<3%/min to reduce folds; multi-directional forging of special-shaped parts to ensure structural isotropy.

 

3. Pwm thiab Khoom Siv raws li txoj cai

Txais siab -precision insert pwm, siv cov cua sov ua kom haum rau pwm preheating kub nrog forging kub, thiab nruab nrog ib tug meej kub tswj system nrog ib tug kub tswj qhov tseeb ntawm ± 3 degree; ua kev soj ntsuam cov pwm tsis tu ncua, zom cov kab nrib pleb me me kom raws sijhawm thiab xyuas kom cov fillet Loj dua lossis sib npaug li 2 hli, thiab kho qhov hnav ntawm flash grooves nrog hluav taws xob tawm machining kom tshem tawm qhov tsis xws li pwm misalignment thiab galling.

 

Tom qab-forging kev kho mob thiab kev soj ntsuam zoo yog cov kab kawg ntawm kev tiv thaiv: ua cov phiaj xwm kev kho cua sov raws li cov yam ntxwv ntawm cov khoom, normalize tom qab forging los ua kom zoo nplej rau qib ASTM 6-7, thiab ntxiv annealing rau forgings loj kom tshem tawm kev ntxhov siab; temper qhov tseem ceeb los txhim kho cov khoom siv kho kom zoo, thiab pab nrog kev txhaj tshuaj peening kom ntxiv dag zog rau saum npoo compressive kev ntxhov siab thiab ua rau lub neej qaug zog. Kev tshuaj xyuas zoo yuav tsum tau kuaj xyuas qhov tsis zoo ntawm ultrasonic los xyuas qhov tsis xws luag, kev tshuaj ntsuam metallographic los txheeb xyuas cov qoob loo loj dua lossis sib npaug rau qib 5, thiab kev ntsuas nruj ntawm tensile lub zog, cuam tshuam lub zog, thiab lwm yam., kom ntseeg tau tias kev ua raws cai.

 

 

Precision forging tau tso lub hauv paus ruaj khov rau siab -kev tsim khoom kawg nrog nws peb qhov zoo. Kev tswj tsis raug yuav tsum muaj tag nrho - txheej txheem tswj thiab tswj. Nyob rau hauv lub neej yav tom ntej, nws yuav txhim kho mus rau kev txawj ntse, greenization, thiab ultra-precision, txhawb lub siab - kev kho kom zoo ntawm kev lag luam xws li aerospace thiab tshiab zog tsheb.
