Forging Tuyog cov txheej txheem tshem tawm cov kev tsis txaus siab saum npoo ntawm kev tsis lees paub los ntawm cov tshuab lossis cov qauv siv tshuaj. Txhawm rau txhim kho qhov tsis zoo ntawm kev lom zem, txhim kho cov kev txiav txim siab saum npoo av thiab kev tso cai kom ntxuav cov tsiaj thiab kev zam txim thaum twg los tau ua cov txheej txheem forging.
Txhawm rau txhim kho qhov chaw zoo ntawmZam txim, txhim kho kev txiav txim ntawmZam tximthiab tiv thaiv qhov xwm txheej nto los ntawm kev nthuav dav, nws yuav tsum tau ntxuav cov plaub ntawm bille thiabZam tximLub sijhawm twg los tau hauvForging txheej txheem. Kev muag tshuaj hlaufeem ntau yog rhaub ua ntejkev zamNrog hlau txhuam lossis cov cuab yeej yooj yim los tshem tawm cov ntsuas oxide. Qhov seem uas muaj cov ntu loj tuaj yeem tuaj yeem ntxuav los ntawm kev txhaj dej siab siab. Nplai rau kev zam txim rau kev zam txim tuaj yeem tshem tawm ntawm pickling los yog blasting (pellets). Tsis yog alloy oxide nplai yog tsawg dua, tab sis tom qab forging tu, kom raws sij hawm thiab tshem tawm saum npoo deg. Cov nplaim hluav taws xob tsis xws luag ntawm billet lossis forgings tsuas yog suav nrog cov kab nrib pleb, quav, khawb thiab suav nrog. Yog tias cov kev tsis haum no tsis raug tshem tawm hauv lub sijhawm, lawv yuav muaj kev tsis zoo ua ntej, tshwj xeeb ntawm txhuas, magnesium, Titanium thiab lawv cov alloys. Cov kev tsis xws luag tom qab pickling ntawm cov tsis ferrous alloy kev tsis lees paub tsis pub noj nrog cov ntaub ntawv, scrapers, grindatic cov cuab yeej. Cov tsis xws luag ntawm cov hlau tsis lees paub yog ntxuav los ntawm pickling, xuab zeb blasting (tua), rab phom blasting, cov menyuam, kev co thiab lwm txoj hauv kev.

Acid tu

Tshem tawm cov hlau oxides los ntawm tshuaj lom neeg cov tshuaj tiv thaiv. Rau cov ntawv me me thiab nruab nrab yog feem ntau thauj mus rau hauv pob tawb hauv cov kab, tom qab tshem tawm cov roj, pickling corrosion, yaug, ziab thiab lwm yam txheej txheem. Tus qauv pickling muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ua tau zoo huv si, tsis muaj kev zam txim ntawm cov duab thiab tsis muaj kev txwv tsis pub muaj kev lom zem. Pickling cov txheej txheem tshuaj tiv thaiv yuav tsis muaj kev phom sij, yog li ntawd, chav pickling yuav tsum muaj lub zog tso pa. Pickling sib txawv hlau forgings yuav tsum xaiv cov sib txawv acid thiab muaj kev sib xyaw ua ke raws li cov hlau hluav taws xob, thiab saws cov qauv pickling (kub, sijhawm thiab tu txheej txheem).

Xuab zeb blasting (tua) thiab txhaj tshuaj tiv thaiv blasting tu
Nrog compressed cua raws li lub zog ntawm sandblasting (txhaj), ua kom cov xuab zeb lossis siv hlua khi ua haujlwm siab ntawm 0.5 ~ ntaus tawm ntawm oxide nplai. Txhaj tshuaj blasting yog los ntawm kev kub ceev (2000 ~ Min1000 Sandblasting plua plav, tsis tshua muaj ntau yam ua tau zoo, tus nqi siab, ntau ntxiv rau cov khoom siv tshwj xeeb, tab sis yuav tsum tau ua cov hmoov av ua haujlwm tau zoo. 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 rau nws cov kev ua haujlwm siab thiab kev noj tsawg.
Tua clening thiab txhaj tshuaj blasting tu kom huv, tib lub sijhawm, ua rau pom kev ua haujlwm oxide, ua haujlwm kom zoo rau kev txhim kho cov neeg qaug zog tsis kam txhim kho qhov chaw. Txog kev zam txim tom qab quenching lossis quenching thiab tempering hardening cov nyhuv, lub hardness tuaj yeem nce los ntawm hardening txheej tuaj yeem ncav cuag 0.3 ~ 0.5mm. Hauv kev tsim khoom raws li cov khoom siv thiab cov kev xav tau ntawm kev zam txim los xaiv cov khoom sib txawv thiab cov khoom me me ntawm cov hlau tua. Kev siv xuab zeb blasting (txhaj tshuaj) thiab txhaj tshuaj tiv thaiv txoj kev los ntxuav cov kev zam txim, cov khoom tawg thiab lwm yam tsis xws luag, yooj yim rau kev ua kom pom kev ploj. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv cov tshuaj sib nqus hlau nplaum lossis tshuaj xyuas lub cev nqaij daim tawv thiab tshuaj lom neeg ntawm kev zam txim saum npoo av.

tumbling
Kev zam txim, nyob rau hauv lub nruas riam, sib tsoo lossis sib tsoo txhua lwm kom tshem tawm cov nplai oxide thiab burr ntawm workpiece. Txoj kev tu no siv cov khoom siv yooj yim thiab yooj yim, tab sis suab nrov nrov. Haum rau me me thiab nruab nrab-nkag dag uas tuaj yeem dais qee yam cuam tshuam thiab tsis yooj yim rau deform. Nruas kev ua kom muaj abrasive tsis muaj abrasive, tsuas yog cov voos loj lossis hlau pob inch ntawm 10 ~ 30mm ntawm tsis muaj abrasive tu, feem ntau yog los ntawm kev sib tsoo kom tshem cov oxide nplai. Lwm tus yog cog quartz xuab zeb, seem sib tsoo cov log tsheb sib tsoo, sopium carbonate, xab npum carbonate, feem ntau yog los ntawm kev sib tsoo rau kev ntxuav.

Kev co tu
Nyob rau hauv cov cuavfings sib xyaw nrog qee qhov kev faib ua feem ntawm abrasives thiab ntxiv, muab tso rau hauv lub thawv ntim, yog li cov neeg ua kom muaj kev sib tsoo thiab burr tawm. Txoj kev ntxuav tu no tsim nyog rau kev ntxuav thiab polishing ntawm cov me thiab nruab nrab-qhov sib thooj ceev kev zam txim.
