Rau tejtitanium teecov yeeb nkab fittings, vim hais tias ntawm lawv txoj kab uas hla me me thiab nyias phab ntsa, qhov yuav tsum tau tiv taus siab. Casting yog qhov nyuaj thiab nws qhov zoo tsis tuaj yeem lav. Yog tias ob lub kav dej ncaj nraim yog welded rau daim ntawv, vim tias qhov vuam seam yog qhov chaw sib tshuam ntawm ob lub tog raj kheej, nws yog qhov nyuaj heev los tuav lub blanking thiab vuam ua haujlwm. Tsis tas li ntawd, qhov loj ntawm cov khoom me me, thiab qhov vuam zoo ntawm cov phab ntsa sab hauv tsis tuaj yeem tswj tau yooj yim. Casting thiab vuam, txawm tias lawv cov duab tuaj yeem tsim tau, tsis tuaj yeem zam tau vim muaj cov pore slag thaum lub sijhawm ua haujlwm, thiab cov txheej txheem tsis raug tso cai rau cov kav dej nruab nrab thiab siab.
Cov kws kho mob tau pom zoo siv cov txheej txheem tuag forging lossis radial extrusion los ua T-zoo li cov khoom tsis zoo ua ntej thiab tom qab ntawd drilling qhov nyob rau hauv kab rov tav thiab ntsug. Txawm li cas los xij, cov txiaj ntsig kev sim qhia tau hais tias qhov zoo ntawmtitanium teecov yeeb nkab tsis yooj yim los tswj. Tsis tas li ntawd, cov txheej txheem muaj qhov tsis zoo xws li ntau cov txheej txheem ua, cov khoom siv loj yuav tsum tau ua, thiab kev siv cov khoom siv hlau tsawg.
Thaum kawg, tus kws tshaj lij txiav txim siab siv txoj hlua ncaj ncaj extrusion txoj kev, muab lub raj ncaj nraim uas muaj cov muab tub lim rau hauv qhov tuag kab noj hniav, kaw lub Upper thiab qis tuag, thiab ces thawb nrog tib txoj kab uas hla Jack (2 pieces) ntawm tib lub ceev los ntawm ob sab. Lub titanium raj nyob rau hauv qhov tuag kab noj hniav yuav inevitably tsim yas deformation nyob rau hauv lub siab ntawm ob kawg. Upsetting los yog extrusion raws radial qhov hauv qhov tuag.
Kev ntxhov siab deformation yog tsis yooj yim sua vim hais tias lub raj yog ntim nrog incompressible muab tub lim. Yog li ntawd, lub raj ncaj yog extruded nrog cov muab tub lim los ntawm lub qhov radial qhib hauv qhov tuag nyob rau hauv siab.
Txhawm rau tiv thaiv lub extruded radial yeeb nkab los ntawm tawg nyob rau hauv lub siab sab hauv ntawm lub muab tub lim, ib tug ejector pas nrig yog ntsia nyob rau hauv lub radial bore ntawm cov tuag, thiab txaus siab yog siv rau lub extruded radial ceg yeeb nkab.
Thaum cov ceg extruded ncav cuag qhov ntev yuav tsum tau, qhov yuav tsum tautitanium teecov yeeb nkab tuaj yeem tau txais los ntawm kev qhib qhov tuag thiab tshem tawm cov khoom ntim. Kev xyaum qhia tau hais tias cov yeeb nkab extruded tee muaj tib lub phab ntsa thickness nyob rau hauv peb cov lus qhia, me ntsis upsetting deformation, thiab 2-3 lub sij hawm ntawm txoj kab uas hla ntawm cov yeeb nkab siab npaum li cov extruded ib feem. Tsis tas li ntawd, vim lub zog ib txhij ntawm cov muab tub lim thiab titanium raj hauv pwm kab noj hniav, tsis muaj cov khoom siv khawb ntawm cov phab ntsa sab hauv ntawm lub raj, thiab qhov ntev thiab qhov zoo raws li cov kev xav tau ntawm cov duab kos.
