Kodi kubweretsa superfinishing ndi chiyani?

The superfinishing ndondomeko osati ntchito zonyamula makampani, komanso mu injini, ndi makina mwatsatanetsatane ndi zida ayambanso kugwiritsa ntchito ndondomekoyi.

Kodi kubereka mwapamwamba kwambiri ndi chiyani?

Kunyamula superfinishing ndi njira yosalala yomwe ndi kayendedwe ka chakudya kuti tikwaniritse kugaya pang'ono.

Pamwamba pamaso pa superfinishing nthawi zambiri amatembenuzika molondola ndi pansi. Makamaka, amatanthauza njira yowongolerera yomwe imakhala ndi mphamvu pang'ono pa chogwirira ntchito ndi chida chonyezimira bwino (mwala wamafuta) pansi pa mafuta abwino komanso kuziziritsa, ndikupanga kusuntha kwachangu komanso kwakanthawi kobwerezabwereza pa chogwirira ntchito pozungulira pamalo enaake. liwiro mu ofukula youma workpiece kasinthasintha malangizo.

Kodi udindo wonyamula superfining ndi chiyani?

Mu kupanga ndondomeko ya kugubuduza fani, superfinishing ndi ndondomeko yomaliza ya kubala mphete processing, amene amathandiza kwambiri kuchepetsa kapena kuthetsa kupatuka zozungulira anasiya ndi akupera processing, kukonza zolakwa mawonekedwe ngalande, kuyenga pamwamba roughness, kuwongolera zakuthupi ndi zamakina zapamtunda, kuchepetsa kugwedezeka ndi phokoso la kunyamula, ndikuwongolera ntchito yonyamula.

Ikhoza kufotokozedwa muzinthu zitatu zotsatirazi

1. Ikhoza kuchepetsa kugwedezeka. Pomaliza kumaliza, kuonetsetsa kuti mwala wamafuta nthawi zonse umagwira ntchito pamtunda wa mafunde ndipo sukhudzana ndi ufa, arc ya mwala wamafuta imalumikizana ndi chogwirira ntchito ≥ kutalika kwa mawonekedwe a waviness. pamwamba pa workpiece, kotero kuti kukhudzana kupanikizika kwa Crest ndi kwakukulu, ndipo nsonga ya convex imachotsedwa, potero kuchepetsa kugwedezeka.

2. Konzani zolakwika za polowera mpira. Kumaliza kwapamwamba kumatha kukonza zolakwika za groove pafupifupi 30% ya misewu yothamanga.

3. Ikhoza kutulutsa kupsinjika kwapang'onopang'ono pamwamba pa kugaya bwino kwambiri. M'kati mwa superfinishing, ozizira pulasitiki mapindikidwe makamaka kwaiye, kotero kuti pambuyo superfinishing, yotsalira compressive kupsyinjika aumbike pamwamba pa workpiece.

4. Ikhoza kuwonjezera malo okhudzana ndi malo ogwirira ntchito a ferrule. Pambuyo wapamwamba-kumaliza, kukhudzana kubala m'dera la ntchito padziko ferrule akhoza ziwonjezeke kuchokera 15% ~ 40% akupera 80% ~ 95%.

Kukhala ndi superfinishing process:

1. Kudula kwa ma bere

Pamene pamwamba pa mwala wokutira ndi kukhudzana ndi otukukira nsonga ya akhakula raceway pamwamba, chifukwa cha malo ang'onoang'ono kukhudzana ndi mphamvu yaikulu pa unit dera, pansi pa zochita za kupsyinjika kwina, mwala wogaya poyamba kugonjetsedwa. "Kudula m'mbuyo" kwa chogwirira ntchito, kotero kuti mbali ya abrasive particles pamwamba pa mwala woperayo imagwa ndikuphwanyika, kuwulula njere zakuthwa zatsopano ndi kudula. m'mphepete. Panthawi imodzimodziyo, kuphulika kwa pamwamba kwa workpiece kumadulidwa mofulumira, ndipo chiwombankhanga ndi kugaya zowonongeka pamwamba pa chogwirira ntchito zimachotsedwa ndi kudula ndi kubweza. Gawoli limatchedwa gawo lodula, ndipo ili panthawiyi pomwe ndalama zambiri zachitsulo zimachotsedwa.

2. Kudula theka la ma bere

Pamene Machining akupitirira, pamwamba pa workpiece kubala pang'onopang'ono yosalala. Panthawiyi, malo okhudzana ndi pakati pa mwala wogaya ndi pamwamba pa workpiece akuwonjezeka, kupanikizika kwa gawo la unit kumachepa, kudula kwakuya kumachepa, ndipo mphamvu yodulira imachepa. Panthawi imodzimodziyo, ma pores pamwamba pa mwala wogaya amatsekedwa, ndipo mwala wogaya uli mu semi-cutting state. Gawoli limadziwika kuti siteji yodulira theka ya kumaliza kumaliza, pomwe zizindikiro zodulira pamwamba pa chogwirira ntchito zimakhala zopepuka komanso zimakhala ndi gloss yakuda.

3. Pomaliza siteji

Gawoli likhoza kugawidwa m'magulu awiri: imodzi ndi siteji yosinthira; Yachiwiri ndi siteji yopera mutasiya kudula

Gawo losinthira:

Njere ya abrasive imadzipangira yokha, m'mphepete mwa njere ya abrasive imakhala yosalala, chip oxide imayamba kulowetsedwa m'malo opanda mwala wamafuta, ufa wonyezimira umatsekereza pores miyala yamafuta, kotero kuti njere zowononga zitha kudulidwa. mofooka, limodzi ndi extrusion ndi akupera, ndiye roughness pamwamba pa workpiece mofulumira yafupika, ndi pamwamba pa mafuta mwala Ufumuyo ndi wakuda Chip okusayidi.

Letsani gawo lodula:

Mwala wamafuta ndi kukangana kwa workpiece wina ndi mnzake kwakhala kosalala kwambiri, malo olumikizirana akuchulukirachulukira, kutsika kwamphamvu, njere ya abrasive yatha kulowa mufilimu yamafuta ndikulumikizana ndi workpiece, pomwe kupanikizika kwa filimu yamafuta pamtunda wonyamula. imagwirizana ndi kuthamanga kwa miyala yamafuta, mwala wamafuta umayandama. Pakupanga filimu yamafuta, palibe zotsatira zodula. Gawoli ndi lapadera kwambiri.
