Chofunika ndi kukhazikitsa kupukuta
N'chifukwa chiyani tiyenera kuchita pamwamba processing pa mbali makina?
Njira yothandizira pamwamba idzakhala yosiyana pazifukwa zosiyanasiyana.
1 Zolinga zitatu zogwirira ntchito pamakina:
1.1 Njira yosinthira pamwamba kuti mupeze kulondola kwagawo
Kwa magawo omwe ali ndi zofunikira zofananira, zomwe zimafunikira kuti zikhale zolondola (kuphatikiza kulondola kwa dimensional, kulondola kwa mawonekedwe ngakhalenso kulondola kwamalo) nthawi zambiri zimakhala zapamwamba, ndipo kulondola ndi kuuma kwa pamwamba kumayenderana. Kuti mupeze kulondola, roughness yofananira iyenera kukwaniritsidwa. Mwachitsanzo: kulondola kwa IT6 nthawi zambiri kumafuna roughness yofananira Ra0.8.
[Njira zamakina wamba]:
- Kutembenuka kapena mphero
- Zabwino zotopetsa
- bwino akupera
- Kupera
1.2 Njira zopangira pamwamba zopezera zinthu zamakina apamwamba
1.2.1 Kupeza kukana kuvala
[Njira zofala]
- Kupera pambuyo kuumitsa kapena carburizing / kuzimitsa (nitriding)
- Kupera ndi kupukuta pambuyo pa plating yolimba ya chrome
1.2.2 Kupeza malo abwino opanikizika
[Njira zofala]
- Kusinthasintha ndi kupera
- Pamwamba kutentha mankhwala ndi akupera
- Kugudubuzika pamwamba kapena kuwomberedwa ndikutsatiridwa ndikupera bwino
1.3 Njira zopangira kuti mupeze zinthu zama mankhwala apamtunda
[Njira zofala]
- Electroplating ndi kupukuta
2 Chitsulo pamwamba kupukuta luso
2.1 Kufunika Ndi gawo lofunika kwambiri laukadaulo wapamwamba komanso uinjiniya, ndipo amagwiritsidwa ntchito kwambiri popanga mafakitale, makamaka m'makampani opanga ma electroplating, zokutira, anodizing ndi njira zingapo zamankhwala zamankhwala.
2.2 Chifukwa chiyani magawo oyamba padziko lapansi ndi magawo omwe akwaniritsidwa a workpiece ndi ofunika kwambiri?Chifukwa ndizomwe zimayambira ndi zomwe zimayang'ana pa ntchito yopukutira, yomwe imatsimikizira momwe mungasankhire mtundu wa makina opukutira, komanso kuchuluka kwa mitu yopukutira, mtundu wazinthu, mtengo, ndi magwiridwe antchito ofunikira pamakina opukutira.
2.3 Kupera & Kupukuta Magawo ndi Njira
The anayi wamba magawo akugayandikupukuta ] : molingana ndi roughness koyamba ndi komaliza Ra mfundo za workpiece, coarse akupera - chabwino akupera - chabwino akupera - kupukuta. Ma abrasives amasiyana kuchokera ku zowawa mpaka zabwino. Chida chopera ndi ntchito ziyenera kutsukidwa nthawi zonse zikasinthidwa.
2.3.1 Chida chogaya chimakhala chovuta kwambiri, chodula chaching'ono ndi chowonjezera chimakhala chachikulu, ndipo kukula kwake ndi roughness zimakhala ndi kusintha koonekeratu.
2.3.2 Kupukuta kwamakina ndi njira yodula kwambiri kuposa kugaya. Chida chopukutira chimapangidwa ndi zinthu zofewa, zomwe zimatha kuchepetsa kuuma koma sizingasinthe kulondola kwa kukula ndi mawonekedwe. Kukula kumatha kufika kuchepera 0.4μm.
2.4 Mfundo zitatu zazing'ono za mankhwala omaliza pamwamba: kugaya, kupukuta, ndi kumaliza
2.4.1 Lingaliro la makina akupera ndi kupukuta
Ngakhale kuti kugaya ndi makina opukuta kungathe kuchepetsa kuuma kwa pamwamba, palinso zosiyana:
- 【Makina kupukuta】: Zimaphatikizapo kulolerana kwa mawonekedwe, kulolerana kwa mawonekedwe ndi kulolerana kwamalo. Ayenera kuonetsetsa kulolerana dimensional, kulolerana mawonekedwe ndi kulolerana malo a padziko lapansi pamene kuchepetsa roughness.
- Kupukuta pamakina: Kumasiyana ndi kupukuta. Zimangowonjezera kutha kwapamwamba, koma kulolerana sikungatsimikizidwe modalirika. Kuwala kwake ndikwapamwamba komanso kowala kuposa kupukuta. Njira yodziwika bwino yopukutira makina ndikupera.
2.4.2 [Kumaliza kukonza] ndi njira yopera ndi yopukutira (yofupikitsidwa ngati ikupera ndi kupukuta) yomwe imachitika pazitsulo zogwirira ntchito pambuyo pokonza bwino, popanda kuchotsa kapena kuchotsa chinthu chochepa kwambiri, ndi cholinga chachikulu chochepetsera roughness pamwamba, kuonjezera gloss pamwamba ndi kulimbikitsa pamwamba pake.
Kulondola ndi kukhwima kwa gawolo kumakhudza kwambiri moyo wake ndi ubwino wake. Wosanjikiza wowonongeka wosiyidwa ndi EDM ndi ming'alu yaying'ono yosiyidwa ndikupera idzakhudza moyo wautumiki wa magawowo.
① Njira yomaliza imakhala ndi gawo laling'ono lamachining ndipo imagwiritsidwa ntchito makamaka kuwongolera mawonekedwe apamwamba. Zochepa zimagwiritsidwa ntchito kuwongolera kulondola kwa makina (monga kulondola kwa dimensional ndi kulondola kwa mawonekedwe), koma sizingagwiritsidwe ntchito kuwongolera kulondola kwamalo.
② Kumaliza ndi njira yodula pang'onopang'ono ndikutulutsa pamwamba pa workpiece ndi ma abrasives owala bwino. Kumtunda kumakonzedwa mofanana, mphamvu yodula ndi kudula kutentha ndi kochepa kwambiri, ndipo khalidwe lapamwamba kwambiri likhoza kupezeka. ③ Kumaliza ndi njira yosinthira pang'ono ndipo sikungakonze zolakwika zazikulu. Fine processing ayenera kuchitidwa pamaso processing.
Akamanena za zitsulo pamwamba kupukuta ndi pamwamba kusankha yaying'ono kuchotsa processing.
3. Panopa okhwima kupukuta ndondomeko njira: 3.1 makina kupukuta, 3.2 mankhwala kupukuta, 3.3 electrolytic kupukuta, 3.4 akupanga kupukuta, 3.5 madzimadzi kupukuta, 3.6 maginito akupera kupukuta,
3.1 Kupukuta kwamakina
Kupukuta kwamakina ndi njira yopukutira yomwe imadalira kudula ndi kusinthika kwa pulasitiki kwa zinthu zakuthupi kuti zichotse zotulutsa zopukutidwa kuti zipeze malo osalala.
Pogwiritsa ntchito luso limeneli, makina kupukuta akhoza kukwaniritsa roughness pamwamba Ra0.008μm, amene ali apamwamba kwambiri mwa njira zosiyanasiyana kupukuta. Njirayi imagwiritsidwa ntchito nthawi zambiri muzojambula za lens.
3.2 Kupukuta kwa Chemical
Kupukuta kwa Chemical ndikupangitsa kuti tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tisungunuke m'malo opangira mankhwala pamwamba pa ma concave, kuti pakhale malo osalala. Ubwino waukulu wa njirayi ndikuti sichifunikira zida zovuta, imatha kupukuta zida zogwirira ntchito ndi mawonekedwe ovuta, imatha kupukuta zida zambiri nthawi imodzi, komanso ndiyothandiza kwambiri. Nkhani yaikulu ya mankhwala kupukuta ndi kukonzekera madzi opukutira. Kuuma kwapamwamba komwe kumapezeka ndi kupukuta kwamankhwala nthawi zambiri kumakhala makumi angapo a μm.
3.3 Electrolytic polishing
Electrolytic polishing, yomwe imadziwikanso kuti electrochemical polishing, imasungunula tinthu tating'onoting'ono pamwamba pa zinthuzo kuti pamwamba pazikhala bwino.
Poyerekeza ndi kupukuta kwa mankhwala, zotsatira za cathode reaction zimatha kuthetsedwa ndipo zotsatira zake zimakhala bwino. Njira yopukuta ya electrochemical imagawidwa m'magawo awiri:
(1) Macro-leveling: Zinthu zosungunuka zimafalikira mu electrolyte, ndipo kuuma kwa geometric kumachepa, Ra 1μm.
(2) Kusalala kwa gloss: Anodic polarization: Kuwala kwapamwamba kumakhala bwino, Ralμm.
3.4 Akupanga kupukuta
The workpiece anayikidwa mu abrasive kuyimitsidwa ndi anaika akupanga kumunda. The abrasive ndi pansi ndi opukutidwa pa workpiece pamwamba ndi oscillation wa akupanga yoweyula. Akupanga Machining ali ang'onoang'ono macroscopic mphamvu ndipo sadzachititsa mapindikidwe workpiece, koma tooling n'zovuta kupanga ndi kukhazikitsa.
Akupanga Machining akhoza pamodzi ndi mankhwala kapena electrochemical njira. Pamaziko a njira dzimbiri ndi electrolysis, akupanga kugwedera umagwiritsidwa ntchito kusonkhezera njira kupatutsa kusungunuka mankhwala pa workpiece pamwamba ndi kupanga dzimbiri kapena electrolyte pafupi padziko yunifolomu; cavitation zotsatira za akupanga mafunde mu madzi akhoza ziletsa dzimbiri ndondomeko atsogolere pamwamba kuwala.
3.5 Kupukuta kwamadzimadzi
Kupukuta kwamadzimadzi kumadalira madzi othamanga kwambiri komanso tinthu tating'onoting'ono tomwe timanyamula kuti timatsuka pa workpiece kuti tikwaniritse cholinga cha kupukuta.
Njira zomwe zimagwiritsidwa ntchito nthawi zambiri zikuphatikizapo: abrasive jet processing, liquid jet processing, madzimadzi akupera, etc.
3.6 Maginito akupera ndi kupukuta
Kupera ndi kupukuta ndi maginito kumagwiritsa ntchito maginito abrasives kupanga maburashi onyezimira pansi pa mphamvu ya maginito kuti akupera chogwirira ntchito.
Njira imeneyi ali mkulu processing dzuwa, khalidwe labwino, kulamulira mosavuta zinthu processing, ndi zinthu zabwino ntchito. Ndi ma abrasives oyenerera, kuuma kwapamwamba kumatha kufika Ra0.1μm.
Kudzera m'nkhaniyi, ndikukhulupirira kuti mumvetsetsa bwino za kupukuta. Mitundu yosiyanasiyana ya makina opukutira adzazindikira zotsatira, mphamvu, mtengo ndi zizindikiro zina za kukwaniritsa zolinga zosiyanasiyana zopukutira.
Ndi mtundu wanji wa makina opukutira omwe kampani yanu kapena makasitomala anu amafunikira sayenera kufananizidwa molingana ndi chogwiriracho chokha, komanso kutengera zomwe wogwiritsa ntchito amafuna pamsika, momwe ndalama, chitukuko cha bizinesi ndi zina.
Inde, pali njira yosavuta komanso yothandiza yothanirana ndi izi. Chonde funsani ogwira nawo ntchito omwe amagulitsa kale kuti akuthandizeni.
