Obwerawa abrasive amasankha mtengo wa peening

Mtengo wa aliyense abrasive anatsimikiza ndi kuchuluka, khalidwe ndi ndalama za workpiece kukonzedwa pa nthawi Unit (kuphatikizapo abrasive, consumable ndi ntchito).
Pakali pano, ena abrasives mkulu kuuma (mapiritsi chitsulo, mchenga chitsulo) pa msika mungathe mwamsanga woyera (kapena kulimbikitsa), mtengo abrasive ndi otsika, koma izi mowa abrasive ndi mkulu & zosalimba, mpirawo kabotolo zida atavala mbali kuvala kale (Sinthanitsani zida kuvala mbali pamene kufunika kusiya, kuonjezera ndalama yokonza), pali kwambiri ndalama opaleshoni ndipo si ntchito M'malo mwake, ena abrasives ena (monga otsika kuuma abrasive), ngakhale kuti pali otsika mowa mlingo ndi otsika Price, ali yaitali kuyeretsa adzizungulira, zokolola otsika, akungotaya ntchito ndi opaleshoni nthawi, abrasives izi sangathe ntchito.
Mu mpirawo kabotolo zipangizo, ndi particles abrasive ali n'kuthamangitsidwa mawilo mkulu-liwiro onsewo (kapena nozzles mpweya) pa liwiro lalitali kwambiri pofikira pamwamba pa workpiece ndi kumaliza ntchito, kulimbikitsa ntchito, ndi mbamu zimakhudzira pamwamba wa workpiece nthawi iliyonse, The pellets okha imvera zimakhudzira mowa, pamene zida chifukwa cha kuwonongeka ndi misozi, kudzera makope mosalekeza ndiponso mobwerezabwereza zodabwitsa, kuyambira pa tinthu mubwatolo particles kakang'ono, kuyambira pa tinthu tating'ono ting'ono kuti particles ang'onoang'ono, ndipo potsiriza chifukwa particles ndi ang'ono kwambiri (osakwana 0.2mm) Ndipo sangathe ntchito, chitakonzedwa ndi fumbi dongosolo kuchotsa.
Mlingo avale a zigawo zikuluzikulu za mpirawo kabotolo zida amakhudza ndalama zina zogwiriramo ntchito komanso deta avale mlingo wa mbali akhoza msanga analandira powonjezera chitsulo mchenga, wamba zitsulo kudula piritsi (wapamwamba muyezo m'litali, Mipikisano bevel ngodya) kapena chiwerengero chachikulu ndi zitsulo mpira kusakaniza mu zipangizo, Mwachindunji kuchepetsa mbali moyo wa 50% -80%.
Kuuma kwa abrasive amakhudza kuyeretsa liwiro ndi quality, mkulu kuuma abrasive amakhudza kuyeretsa liwiro, ndi sichisinthasinthanso ndi mapeto a workpiece lapansi. Pansi bwinobwino zinthu, ndi kuwumitsa osiyanasiyana abrasive wa HRC40-50 abwino, kuswa mosavuta chifukwa molimbika, kuti mapindikidwe kwa zofewa. Kukula kwa abrasive ndiyo kuyeretsa khalidwe (mapeto).
Obwerawa abrasive amasankha mtengo wa peening:
Zitsulo kuwombera ntchito kulimbana ndi ang'ono, ndi kuuma yoyenera, mkulu sichisinthasinthanso, ukhondo ndi mkulu pamene mosalekeza kabotolo pamwamba ntchito, koma si kophweka kuthamangitsa pamlingo winawake roughness, zofunika za ❖ kuyanika mbali muyezo padziko roughness ndi zimakhudza kwambiri utoto Kakhungu guluu wolimba, kukana dzimbiri ndi moyo zozitetezera. The roughness wa padziko workpiece abwino kusintha kwa katundu poteteza filimu, ndi roughness ndi yaing'ono kwambiri, si abwino kusintha kwa guluu wolimba wa utoto, roughness ndi waukulu kwambiri, monga kuchuluka kwa utoto filimu ndi ena, izo adzachititsa filimu makulidwe likamaomba, makamaka pa nsonga ya makulidwe filimu sikokwanira ndi poyerekeza amafuna kapangidwe kuchititsa dzimbiri oyambirira, mu komanso, roughness ndi waukulu kwambiri, komanso nthawi zambiri mu maenje chozama ufa kukumbukira kuwira, adzakhala muzu wa filimu kuwira.
Pakuti ❖ kuyanika amagwiritsidwa ntchito ndi roughness oyenerera ndi osiyanasiyana monga ku 39-75um. Kotero ayenera kukhala wololera ntchito wosanganiza abrasive, kuwonjezera zitsulo grit moyenera. Chiwerengero yeniyeni malinga ndi ❖ kuyanika amafuna muyezo, chotero mwamsanga kuyeretsa (bwino ntchito) ndi wopambana anawomberedwa peening zida avale yochepa (ndalama ulamuliro zida yokonza) ndi yabwino ziyeneretso ❖ kuyanika (kuchepetsa utoto zinyalala ), Choncho kuchepetsa mtengo wonse.
