Forging: Nws muab faib ua ob pawg loj: qhib- tuag forging thiab tuag forging.
1. Qhib- tuag forging
Lub hom phiaj: Feem ntau yog siv los tsim ib nrab- cov khoom tiav xws li cov khoom tuav, cov ntawv nplaum, lossis cov nplhaib, lossis los npaj cov ntawv hlau rau kev tuag forging.
Khoom siv: Hydraulic xovxwm (nyiam dua, qeeb qeeb yog qhov zoo rau titanium alloy deformation) lossis forging rauj.
Cov ntsiab lus tseem ceeb: Tswj tus nqi thiab tus nqi ntawm deformation, siv 'lub teeb- hnyav- lub teeb' forging txoj kev, lub ntsiab lus lub teeb tshuab thaum pib thiab xaus, hnyav tshuab nyob rau hauv nruab nrab, kom ntseeg tau tias tag nrho forging thiab tiv thaiv kom txhob kub dhau heev lawm.
2. Forging: Los tsim cov khoom uas muaj cov duab sib txawv thiab qhov ntev, xws li cov khoom siv dav hlau, cov hniav, thiab cov disks.
3. Kev faib tawm
- cheeb tsam forging: Txoj kev siv feem ntau. Lub microstructure tom qab forging yog equiaxed los yog bimodal, nrog zoo tag nrho cov khoom (lub zog, plasticity, qaug zog).
cheeb tsam forging: Ua nyob rau hauv theem cheeb tsam, lub deformation kuj yog tsawg, tso cai rau loj deformations nyob rau hauv ib qho kev lag luam, txuag zog. Txawm li cas los xij, microstructure tom qab forging yog lamellar; Txawm hais tias tawg toughness thiab creep zog kuj zoo, plasticity thiab qaug zog zog feem ntau qis dua cov ntawm - forgings.
Trimming thiab tu
Flash yuav tsum tau muab tshem tawm tom qab forging. Titanium alloy trimming feem ntau yog ua nyob rau hauv lub xeev kub (tam sim ntawd tom qab forging) vim hais tias nws yog ib qho nyuaj rau luas nyob rau hauv lub xeev txias thiab cov kab nrib pleb yog yooj yim generated. Txoj kev ntxuav oxides muaj xws li sandblasting, pickling (feem ntau yog siv HF-HNO3 sib tov), los yog machining.
Kev kho cua sov
Annealing: Cov txheej txheem kev kho cua sov feem ntau yog siv los tshem tawm cov kev ntxhov siab sab hauv, txhim kho microstructure, thiab txhim kho plasticity thiab stability.
Kev Kho Mob thiab Kev Laus: Rau cov cua sov- kho tau cov alloys (xws li TC4), qhov no yog siv los ua kom muaj zog.
Kev tshuaj xyuas
Xws li kev tshuaj xyuas qhov ntev, qhov tsis xws luag ntawm qhov chaw (kev tawg, folds, thiab lwm yam) kev kuaj xyuas, kev kuaj ultrasonic rau sab hauv qhov tsis xws luag, nrog rau cov cuab yeej cuab tam thiab kev tshuaj xyuas metallographic.
