Forging tsis xws luag
Lub hom phiaj ntawm kev foulding yog los nias lub porcasic qhov tsis xws luag ntawm cov hlau ingot kom tus qauv ntom thiab tau txais ib txoj kab zoo hlau ntws. Cov txheej txheem tsim yog kom nws kaw tau raws li qhov ua tau rau cov duab ntawm cov workpiece. Cov tsis xws luag tau tsim tawm thaum lub sij hawm zam txim tsuas yog suav nrog cov kab nrib pleb, sab hauv forging tsis xws luag, oxide nplai thiab quav, unqualified qhov ntev, thiab lwm yam.
Lub ntsiab ua rau cov kab nrib pleb yog overheating ntawm cov hlau ingot thaum cua sov, thiab ntau dhau los ua kom yooj yim ua rau tawg nyob rau hauv lub sijhawm ntxov ntawm forging. Thaum qhov kev zam txim yog tsawg heev, cov khoom nws tus kheej muaj kev zam tsis zoo thaum lub sijhawm tsis yooj yim thaum lub sijhawm lossis tsis huv, uas tuaj yeem yooj yim ua rau cov kab nrib pleb kom nthuav ntxiv. Kev tso siab sab hauv tsis xws luag yog tshwm sim los ntawm cov khoom siv tsis txaus ntseeg, lub siab tsis tuaj yeem hloov pauv thaum lub sij hawm ingot tsis tag pressed, thiab cov nplej dendritic yog Tsis tag nrho tawg shrinkage thiab lwm yam tsis xws luag. Qhov laj thawj tseem ceeb rau nplai thiab folding yog tias cov nplai tsim tawm thaum lub sijhawm tsis txhob forging, lossis nws yog tshwm sim los ntawm cov txheej txheem forging tsis muaj tseeb. Tsis tas li ntawd, cov kev tsis zoo no kuj yuav tshwm sim thaum tsis muaj qhov tsis zoo, lossis vim tias nws yog qhov tsis sib xws, nws tuaj yeem tshem tawm los ntawm kev siv tshuab. Ib qho ntxiv, yog tias cov kev ua haujlwm cua sov thiab forging yog tsis raug, nws tuaj yeem ua rau lub axis ntawm workpiece kom ua haujlwm tsis raug cai lossis misaligned. Qhov no yog hu ua eccentricity thiab khoov hauv kev ua haujlwm forging, tab sis cov kev tsis zoo no yog qhov tsis xws luag thaum kev lom zem txuas ntxiv.

Kev tiv thaiv ntawm cov tsis xws luag tshwm sim los ntawm kev forging tsuas yog:

(1) Tsim kom muaj qhov kub kub kom tsis txhob muaj kev kub ntxhov thiab kub hnyav;

(2) Ua kom zoo rau Forging cov txheej txheem, ntau lub chaw yuav kos npe rau cov txheej txheem FORGING thiab ntxiv dag zog rau cov txheej txheem FORGING;

(3) ntxiv dag zog rau cov txheej txheem tswj hwm ntawm kev Forging, nruj me ntsis ua cov txheej txheem, thiab tsis txhob hloov cov kev tsis nco qab txog yuav ua kom muaj kev sib txuas lus ntxiv.
