Kupera ndi njira yodulira chopukusira ndi gudumu lopera ngati chida chodulira.
Makhalidwe a njirayi ndi awa:
1. Chifukwa cha kuuma kwakukulu ndi kukana kutentha kwa abrasives akupera magudumu, kugaya kumatha kukonza zinthu zolimba kwambiri, monga chitsulo cholimba, simenti ya carbide, etc.
2. Makhalidwe a gudumu lopera ndi makina opera amatsimikizira kuti njira yopera ingagwiritsidwe ntchito ngati yunifolomu yodula, kawirikawiri ap=0.001 ~ 0.005mm;Liwiro lopera ndilokwera kwambiri, nthawi zambiri mpaka v=30~50m/s;makina opera ali ndi kuuma bwino;kufala kwa hayidiroliki ntchito, kotero akupera akhoza kupeza mkulu processing kulondola (IT6 ~ IT5) ndi yaing'ono roughness pamwamba (Ra = 0.8 ~ 0.2um).Kupera ndi imodzi mwa njira zazikulu zopangira magawo.
3. Kutentha kwa malo ogaya kumakhala kwakukulu kwambiri chifukwa cha kukangana kwakukulu.Izi zidzayambitsa kupsinjika ndi kusinthika kwa workpiece, komanso kuchititsa kuyaka pamwamba pa workpiece.Choncho, madzi ozizirirapo ambiri amayenera kubayidwa pogaya kuti achepetse kutentha.Zoziziritsa kukhosi zimagwiranso ntchito ngati kuchotsa tchipisi ndi kuthira mafuta
4. Mphamvu yamagetsi pakupera ndi yaikulu kwambiri.Izi zidzachititsa zotanuka chilolezo cha makina chida-akupera gudumu-workpiece dongosolo, kuti kuya kwenikweni odulidwa ndi zosakwana kuya mwadzina.Choncho, pamene akupera ali pafupi kumalizidwa, wodulayo sayenera kuzimitsidwa kuti athetse zolakwika.
5. Pambuyo poti abrasive akupera, mphamvu yowonongeka imakhalanso yowonjezera, yomwe imapangitsa kuti particles abrasive athyole kapena kugwa ndikuwonetsanso nsonga yakuthwa.Khalidweli limakhala "kudzinola".Kunola paokha kumapangitsa kuti ntchito yopera igwire ntchito nthawi yayitali, koma pakapita nthawi yogwira ntchito, iyenera kukonzedwa pamanja kuti ipewe kugwedezeka, phokoso ndi kuwonongeka kwa mawonekedwe apamwamba a workpiece chifukwa cha kuchuluka kwa mphamvu yopera.
gudumu lopera
Magudumu akupera ndi chida chodulira popera.Amakhala ndi tizitsulo tating'ono ndi zolimba komanso zomangira, zomwe zimapangidwa ndi zinthu zambiri zopanda kanthu.Abrasive particles mwachindunji kunyamula ntchito kudula, ayenera kukhala lakuthwa ndi mkulu kuuma, kutentha kukana ndi mlingo wina wa kulimba.Ma abrasives omwe amagwiritsidwa ntchito kwambiri ndi alumina (yemwe amadziwikanso kuti corundum) ndi silicon carbide.
Alumina
Alumina Abrasives ali ndi kuuma kwakukulu, kulimba kwabwino ndipo ndi oyenera kugaya zitsulo.Ma silicon carbide abrasives ali ndi kuuma kwakukulu, akuthwa komanso kutenthetsa bwino, koma ndi opunduka komanso oyenera kugaya chitsulo choponyedwa ndi simenti.
Yemweyo abrasive akupera gudumu, chifukwa makulidwe ake osiyana, roughness pamwamba ndi processing dzuwa la workpiece pambuyo processing ndi osiyana.Abrasive ya coarse imagwiritsidwa ntchito pogaya movutikira.The abrasive bwino ndi, coarser ndi abrasive ndi, ang'onoang'ono tinthu kukula ndi.
Zomangira zimakhala ngati zomangira zomangira.
Ceramic binder imagwiritsidwa ntchito kwambiri, ndikutsatiridwa ndi resin binder.Kusankhidwa kosiyanasiyana kwa binder kumakhudza kukana kwa dzimbiri, mphamvu, kukana kutentha komanso kulimba kwa gudumu lopera.
Chomangira cholimba cha abrasive chimakhala chovuta kwambiri kugwa kuchokera ku gudumu lopera.Ndiko kunena kuti, kuuma kwa gudumu lopera kumatanthawuza momwe tinthu tating'ono ta abrasive pamwamba pa gudumu lopera timagwera pansi pa mphamvu ya kunja.Zosavuta kugwa zimatchedwa zofewa, ndipo mosiyana zimatchedwa zolimba.
The kuuma gudumu akupera ndi abrasive ndi mfundo ziwiri zosiyana.Pamwamba pa chopukutira chopukutira ndi chofewa, ndipo m'mphepete (m'mphepete) wa tinthu tating'onoting'ono sizovuta kuvala, kotero kuti tinthu tating'onoting'ono titha kugwiritsidwa ntchito kwa nthawi yayitali, kutanthauza kuti, gudumu lopukuta lokhala ndi mgwirizano wamphamvu ( gudumu lopera lokhala ndi kuuma kwakukulu) likhoza kusankhidwa.M'malo mwake, gudumu lopera lokhala ndi kuuma kochepa ndiloyenera kugaya chogwirira ntchito ndi kuuma kwakukulu.
Pofuna kuonetsetsa chitetezo, mawilo opera ayenera kuyang'aniridwa asanakhazikitsidwe, ndipo pasakhale ming'alu ndi zolakwika zina.Kuti mawilo akupera azigwira bwino ntchito, kuyesa kwamphamvu koyenera kumayenera kuchitidwa musanagwiritse ntchito.
Pamene gudumu lopera likugwira ntchito kwa nthawi inayake, malo ozungulira adzatsekedwa ndi zinyalala, mbali yakuthwa ya abrasive idzakhala yosamveka, ndipo mawonekedwe oyambirira a geometric adzasokonezedwa.Chifukwa chake, ndikofunikira chepetsa kuti mubwezeretse luso lodula ndikuwongolera ma geometry.Gudumu lopera liyenera kudulidwa ndi cholembera cha diamondi.
Kapangidwe ndi Kugaya Kuyenda Kwa Makina Opera Pamwamba
Pali mitundu yambiri ya zopukusira, monga chopukusira pamwamba, cylindrical chopukusira, chopukusira mkati, universal cylindrical chopukusira (amathanso kugaya mabowo amkati), chopukusira giya, chopukusira ulusi, chopukusira njanji, chopukusira chopanda pakati (kupera bwalo lakunja) ndi chopukusira chida ( chida chopera).Chopukusira pamwamba ndi kuyenda kwake zikuyambitsidwa apa.
1. Kapangidwe kapamwamba chopukusira (kutenga M7120A mwachitsanzo: M-chopukusira mtundu makina chida; 71-yopingasa olamulira mphindi tebulo mtundu pamwamba chopukusira; 20-ntchito tebulo m'lifupi 200 mm; A-woyamba kusintha kwakukulu).
(1) Choyikapo gudumu - Ikani gudumu lopera ndikuyendetsa gudumu kuti lizizungulira mwachangu.Choyikapo gudumu logawira chimatha kuyenda motsatira njanji ya dovetail kalozera pampando wotsetsereka pamanja kapena hydraulically podutsa chilolezo.
(2) Mpando wa Slide - ikani choyikapo gudumu ndikuyendetsa chowongolera kuti musunthe mmwamba ndi pansi motsatira njanji yowongolera.
(3) Mzere - wothandizira mpando wotsetsereka ndi chimango chopera.
(4) Workbench - Kuyika kwa workpiece ndi kubwereza kwa mzere woyenda motsogozedwa ndi hydraulic system.
(5) Bedi - kuthandiza worktable ndi khazikitsa mbali zina.
(6) Dongosolo loziziritsa - kupereka zoziziritsa kukhosi (mafuta osakanizidwa) kumalo opera.
(7) Hydraulic transmission system, yomwe ili ndi:
1) Zida zamagetsi - mapampu amafuta, ma hydraulic transmission system pressure mafuta;
2) Actuator - silinda, kuyendetsa kayendedwe ka worktable ndi zigawo zina;
3) Zinthu zowongolera - zamitundu yonse ya mavavu, kuthamanga, kuthamanga, mayendedwe, etc.
4) Zida zothandizira, monga thanki yamafuta, choyezera kuthamanga, etc.
Poyerekeza ndi makina opatsirana, ma hydraulic transmission ali ndi ubwino wa kufalitsa kosalala, chitetezo chodzaza ndi kuwongolera mofulumira mosiyanasiyana.
2. Ndege akupera kuyenda
(1) Kuyenda kwakukulu - kusuntha kothamanga kwambiri kwa gudumu lopera.
(2) Kuyenda chakudya
1) Chakudya chotalikirapo - tebulo logwirira ntchito limayendetsa kusuntha kwa mzere wa workpiece;
2) ofukula chakudya - kuyenda kwa gudumu akupera mpaka kuya workpiece;
3) Kusuntha kwapang'onopang'ono kwa gudumu lopera mozungulira mbali yake.
