Tso cai tuyog cov txheej txheem tshem tawm cov kev tsis xws luag saum npoo ntawmZam tximlos ntawm kev siv tshuab lossis tshuaj lom neeg. Txhawm rau txhim kho qhov chaw zoo ntawmZam txim, txhim kho kev txiav txim ntawmZam tximThiab tiv thaiv cov nplaim loj los ntawm kev nthuav dav, nws yuav tsum ntxuav cov kab thiab kev tsis nco qab txhua lub sijhawm thaum lub sijhawm forging ntau lawm.

Txhawm rau txhim kho qhov tsis zoo ntawm kev zam txim, txhim kho cov kev txiav txim siab ntawm kev quav ntsej muag thiab kev zam txim rau txhua lub sijhawm thaum lub sijhawm forging. Kev quav ntsej muag steel yog feem ntau ntxuav nrog tus hlau txhuam lossis cov cuab yeej yooj yim ua ntej raug forged tom qab cua sov. Billet nrog cov ntu loj tuaj yeem ntxuav tau los ntawm kev txhaj tshuaj hnyav. Cov tawv nqaij oxide rau kev zam txim rau kev zam txim tuaj yeem tshem tawm ntawm pickling lossis blasting. Cov Oxide nplai ntawm tsis yog qhov tsis muaj tsawg dua, tab sis nws yuav tsum tau pickled ua ntej thiab tom qab forging nrhiav thiab tshem tawm qhov tsis xws luag nyob rau hauv lub sijhawm. Cov nplaim hluav taws xob tsis xws luag ntawm billet lossis forging feem ntau tawg, folds, khawb thiab suav nrog. Qhov tsis xws luag no, yog tias tsis tshem tawm raws sijhawm, yuav ua rau muaj kev tsis ncaj ncees rau kev ua tsis tau zoo, ntawm cov khoom siv cuav, magnesium, Titanium thiab lawv cov alloys. Cov kev tsis xws luag tom qab pickling ntawm qhov tsis lees txais cov ntaub ntawv, scrapers, grasting cov khoom siv, graint), cov menyuam, cov menyuam, cov kev co thiab lwm txoj hauv kev.

Acid tu

Tshuaj lom neeg siv tau los tshem tawm cov hlau oxide. Cov pob tawb thiab nruab nrab feem ntau muab tso rau hauv cov txheej txheem hauv cov pob thiab ua tiav los ntawm cov roj tshem tawm, pickling thiab corrosion, yaug thiab tshuab kom qhuav. Tus qauv pickling muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ua tau zoo huv zoo, tsis muaj deformation ntawm kev zam txim thiab cov qauv tsis muaj nuj nqis. Nyob rau hauv cov txheej txheem ntawm pickling tshuaj tiv thaiv, nws yog kev tsis tsim txiaj cov roj ua rau tib neeg lub cev. Yog li ntawd, yuav tsum muaj kev tso pa tawm hauv chav xaiv. Pickling sib txawv cov hlau forgings yuav tsum yog cov hlau hluav taws xob xaiv cov txheej txheem acid thiab muaj kev sib xyaw ua ke, cov txheej txheem txias (kub, sijhawm thiab tu cov txheej txheem).

Xuab zeb blasting (tua) thiab txhaj tshuaj tiv thaiv blasting tu

Xuab zeb blasting (tua) powered los ntawm compressed huab cua ua rau cov xuab zeb lossis steel txhaj tshuaj (cov ua haujlwm siab ntawm kev txhaj tshuaj tiv thaiv blasting yog 0.5-0.6mpa), uas tau muab txau rau ntawm Forging saum npoo los so cov nplai oxide. Txhaj tshuaj blasting nyob rau ntawm centrifugal yuam kev tig impeller ntawm kev kub ceev (2000 ~ min) los tua cov hlau tua rau lubForging saum npookom khob cov nplai oxide. Cov xuab zeb blasting tu plua plav, cov kev ua tau zoo tsawg, siv rau cov khoom siv tshwj xeeb, tab sis yuav tsum siv plua plav ua haujlwm ua haujlwm. Tua cov Pumened kuj kuj huv, kuj tseem muaj kev cuam tshuam ntawm kev ua haujlwm tau zoo thiab cov nqi siab, tab sis kev tu zoo dua yog siab dua. Txhaj tshuaj blasting yog dav siv vim tias nws cov kev ua haujlwm siab thiab kev noj tsawg.

Tua cov peeness thiab txhaj tshuaj tiv thaiv blasting tsis tuaj yeem tsuas yog cov tawv nqaij oxide, tab sis kuj tseem ua rau muaj txiaj ntsig zoo los txhim kho kev nkees nkees ntawm cov khoom. Rau kev tsis lees paub tom qab quenching lossis quenching kev kho mob, ua haujlwm hnyav siv tau ntau dua li 30% ~ 40%, thiab cov tawv tawv tawv tuaj yeem nce mus txog 0.3 ~ 0.5 hli. Hauv kev tsim khoom, steel txhaj tshuaj nrog cov khoom sib txawv thiab cov nplej loj yuav tsum tau xaiv raws li cov ntaub ntawv thiab cov kev xav tau kev xav tau. Yog tias cov kev zam txim yog ntxuav los ntawm blasting (txhaj) thiab txhaj tshuaj blasting, thaj chaw saum npoo thiab lwm yam tsis xws luag yuav raug zais, uas tej zaum yuav yooj yim ua rau kev soj ntsuam ploj. Yog li ntawd, cov hau kev xws li kev soj ntsuam sib nqus lossis cov tshuaj lom neeg fluorection (saib kev ntsuas lub cev thiab tshuaj kho kom raug)

tumbling

Nyob rau hauv lub nruas rotating, cov kev zam txim yog tsoo lossis av kom tshem tawm cov tawv nqaij oxide thiab burrs los ntawm workpiece. Txoj kev tu no siv cov khoom siv yooj yim thiab yooj yim, tab sis yog nrov. Haum rau me me thiab nruab nrab-qhov quav uas tuaj yeem dais qee yam cuam tshuam tab sis tsis yooj yim deform. Cov menyuam huv tsis muaj abrasives, tsuas yog nrog cov voos hlau los yog cov hlau uas tsis muaj abluaives, feem ntau yog los ntawm kev sib nrig sib los ntxuav cov oxide nplai. Lwm tus yog ntxiv abrasive xws li Quartz xuab zeb, seem sib tsoo log, sopium carbonate, xab npum roj, feem ntau yog los ntawm kev sib tsoo kom huv si.

Kev co tu

Ib qho kev faib ua feem ntawm abrasives thiab cov quav ntxiv tau sib xyaw rau hauv cov ntawv tsis lees paub thiab muab tso rau hauv cov thawv vibrating. Los ntawm cov kev co ntawm lub thawv, lub workpiece thiab cov abrasive yog hauv av muaj kev sib yuav, thiab cov tawv nqaij oxide thiab burrs rau saum npoo ntawm cov hauv av. Txoj kev ntxuav tu no yog qhov tsim nyog rau kev ntxuav thiab polishing me me thiab nruab nrab kev lees paub.
