Kuyeretsa kwa forgingsndi njira yochotsera zofooka zapamtundazojambulandi makina kapena mankhwala. Pofuna kupititsa patsogolo khalidwe lapamwamba lazojambula, kusintha mikhalidwe kudula wazojambulandikuletsa zolakwika zapamtunda kuti zisakule, zimafunika kuyeretsa zomwe zilibe kanthu komanso zofooketsa nthawi iliyonse pakupanga kupanga.

Pofuna kukonza mawonekedwe apamwamba a forgings, kukonza malo odulidwa a forgings ndikuletsa zolakwika zapamtunda kuti zisakule, zimafunika kuyeretsa zomwe zilibe kanthu komanso zopangira nthawi iliyonse panthawi yopanga. Zopangira zitsulo nthawi zambiri zimatsukidwa ndi burashi yachitsulo kapena chida chosavuta chisanapangidwe pambuyo potentha. Billet yokhala ndi gawo lalikulu imatha kutsukidwa ndi jakisoni wamadzi wothamanga kwambiri. Khungu la okusayidi pazitsulo zozizira zimatha kuchotsedwa ndi pickling kapena kuphulika. Sikelo ya oxide ya nonferrous alloy ndi yocheperako, koma imayenera kuzifutsa musanayambe kapena mutatha kupanga kuti mupeze ndikuchotsa zolakwikazo pakapita nthawi. Zolakwika zapamtunda za billet kapena forging zimakhala makamaka ming'alu, zopindika, zokopa ndi zophatikizika. Zolakwika izi, ngati sizikuchotsedwa munthawi yake, zitha kubweretsa zotsatira zoyipa pamapangidwe azotsatira, makamaka pa aluminiyamu, magnesium, titaniyamu ndi ma aloyi awo. The zolakwika poyera pambuyo pickling wa nonferrous aloyi forgings zambiri kutsukidwa ndi owona, scrapers, chopukusira kapena pneumatic zida, etc. The zolakwika zitsulo forgings kutsukidwa ndi pickling, kuphulika (kuwombera), kuwombera kuphulika, wodzigudubuza, kugwedera ndi njira zina.

Kuyeretsa asidi

A chemical reaction amagwiritsidwa ntchito kuchotsa chitsulo okusayidi. Zing'onozing'ono ndi zapakati nthawi zambiri zimayikidwa mudengu m'magulu ndipo zimatsirizidwa kupyolera mu njira zingapo monga kuchotsa mafuta, pickling ndi dzimbiri, kutsuka ndi kuyanika. The pickling njira ali ndi makhalidwe a mkulu kupanga dzuwa, zotsatira zabwino kuyeretsa, palibe mapindikidwe forgings ndi malire mawonekedwe. Mu ndondomeko pickling mankhwala anachita, n'zosapeŵeka kutulutsa mpweya wovulaza thupi la munthu. Choncho, payenera kukhala chipangizo chotulutsa mpweya m'chipinda cha pickling. Pickling zosiyanasiyana zitsulo forgings ayenera kukhala malinga ndi katundu zitsulo kusankha osiyana asidi ndi zikuchokera chiŵerengero, lolingana pickling ndondomeko (kutentha, nthawi ndi kuyeretsa njira) dongosolo ayenera kutengera.

Kuwombera mchenga (kuwombera) ndi kuwombera kuphulika kwamoto

Kuphulika kwa mchenga (kuwomberedwa) koyendetsedwa ndi mpweya woponderezedwa kumapangitsa mchenga kapena kuwombera kwachitsulo kuyenda pa liwiro lalikulu (mphamvu yogwira ntchito ya kuphulika kwa mchenga ndi 0.2-0.3mpa, ndipo mphamvu yogwira ntchito yowombera ndi 0.5-0.6mpa), yomwe imapopera pa kupanga pamwamba kuti achotse oxide sikelo. Kuwombera kuwombera kumadalira mphamvu yapakati ya choyikapo chozungulira pa liwiro lalikulu (2000 ~ 30001r/min) kuwombera chitsulo chowomberakupanga pamwambakuchotsa oxide sikelo. Mchenga kuphulika kuyeretsa fumbi, otsika kupanga dzuwa, kukwera mtengo, ntchito zofunika luso lapadera ndi forgings wapadera zipangizo (monga zitsulo zosapanga dzimbiri, titaniyamu aloyi), koma ayenera kugwiritsa ntchito miyeso yogwira fumbi kuchotsa luso. Kuwombera kuwombera kumakhala koyera, palinso zovuta zotsika mtengo komanso zotsika mtengo, koma kuyeretsa ndikokwera kwambiri. Kuwombera kuwombera kumagwiritsidwa ntchito kwambiri chifukwa chopanga bwino kwambiri komanso kugwiritsa ntchito pang'ono.

Kuwombera ndikuwombera kuphulika sikungangochotsa khungu la okusayidi, komanso kumapangitsa kuti pamwamba pazitsulo zigwire ntchito mwakhama, zomwe zimapindulitsa kupititsa patsogolo mphamvu zotsutsana ndi kutopa kwa ziwalo. Pazojambula pambuyo pozimitsa kapena kuzimitsa ndi kutenthetsa mankhwala, kuuma kwa ntchito kumakhala kofunikira kwambiri pamene kuwombera kwakukulu kwachitsulo kumagwiritsidwa ntchito, kuuma kungathe kuwonjezeka ndi 30% ~ 40%, ndipo makulidwe owumitsidwa amatha kufika 0.3 ~ 0.5 mm. Popanga, kuwombera chitsulo ndi zinthu zosiyanasiyana ndi kukula kwambewu ziyenera kusankhidwa molingana ndi zofunikira ndi luso la forgings. Ngati zokopazo zayeretsedwa ndi kuphulika (kuwomberedwa) ndi kuwomberedwa ndi mfuti, ming'alu ya pamwamba ndi zolakwika zina zitha kubisika, zomwe zingapangitse kuti zisawonedwe mosavuta. Chifukwa chake, njira monga kuyang'anira maginito kapena kuyezetsa kwa fluorescence (onani kuwunika kwakuthupi ndi kwamankhwala kwazovuta) ndizofunikira kuti muwone zolakwika zapambuyo pakupanga.

kugwa

Mu ng'oma yozungulira, ma forgings amapunthwa kapena pansi kuti achotse khungu la oxide ndi ma burrs kuchokera pa workpiece. Njira yoyeretserayi imagwiritsa ntchito zida zosavuta komanso zosavuta, koma zimakhala zaphokoso. Ndioyenera kupangira ma forging ang'onoang'ono ndi apakatikati omwe amatha kukhala ndi vuto linalake koma osapunduka mosavuta. Chogudubuza choyera chopanda ma abrasives, chokhala ndi midadada yachitsulo katatu kapena mipira yachitsulo yokhala ndi 10 ~ 30mm yopanda ma abrasives, makamaka molumikizana kuti muyeretse sikelo ya oxide. Zina ndikuwonjezera zonyezimira monga mchenga wa quartz, gudumu logayira zidutswa, sodium carbonate, madzi a sopo ndi zina zowonjezera, makamaka pogaya kuti ayeretse.

Kuyeretsa kwa vibration

Gawo lina la abrasives ndi zowonjezera zimasakanizidwa muzojambula ndikuyikidwa mu chidebe chogwedeza. Mwa kugwedezeka kwa chidebecho, chogwirira ntchito ndi chotupitsa chimaphwanyidwa, ndipo khungu la oxide ndi ma burrs omwe ali pamwamba pa ma forgings amagwa. Njira yoyeretserayi ndi yoyenera kuyeretsa ndi kupukuta mafogi ang'onoang'ono komanso apakatikati.
