Kusiyana pakati pa chitsulo chosapanga dzimbiri chopukutidwa ndi chopukutidwa!
Pankhani ya teknoloji, ndondomeko yojambula waya ndiyo kupanga mawonekedwe okhazikika komanso ofanana pamtunda wa workpiece.Zojambulazo ndizo: mikwingwirima yopyapyala ndi yozungulira.Njira yopukutira ndikupangitsa kuti pamwamba pa workpiece ikhale yosalala, popanda zolakwika, ndipo imawoneka yosalala komanso yosasunthika, yokhala ndi galasi pamwamba.
Pankhani yoyenda, zomwe mawaya amajambula pazida ndi kusuntha kobwerezabwereza, pomwe kupukuta ndi njira yoyendetsera yomwe imachitika pamakina opukutira.Awiriwo ndi osiyana pa mfundo ndi zosiyana muzochita.
Popanga, zida zaukadaulo zamawaya zimagwiritsidwa ntchito pojambula waya, ndipo pali mitundu yambiri ya zida zopukutira molingana ndi mawonekedwe osiyanasiyana kuti zigwirizane ndi zofunikira zosiyanasiyana zopukutira.
Ngati chogwirira ntchito chiyenera kukokedwa ndikupukutidwa, ndi njira iti yomwe iyenera kutsatiridwa ndi yapitayi?
Kuchokera pazimenezi, kuchokera ku zotsatira za kujambula kwa waya ndi kupukuta pamwamba pa mankhwala, komanso ndondomeko ya ndondomekoyi, sizovuta kwa ife kujambula: kupukuta pamaso, kujambula kwa waya pambuyo.Pokhapokha pamwamba pa workpiece ndi kupukutidwa ndi kuphwanyidwa, chojambula cha waya chikhoza kuchitidwa, chifukwa mwanjira imeneyi zotsatira za kujambula kwa waya zidzakhala zabwino, ndipo mizere yojambula waya idzakhala yofanana.Kupukutira ndikotsuka ndikuyika maziko.Mwachidule, ngati chojambula cha waya chikupukutidwa poyamba, osati mawonekedwe a waya okhawo omwe ali osauka, koma mizere yojambula bwino ya waya idzagwedezeka kwathunthu ndi diski yopera panthawi yopukutidwa, kotero palibe chomwe chimatchedwa zotsatira za waya.
Chenjezo pojambula waya wachitsulo chosapanga dzimbiri
1. Brushed (frosted): Kawirikawiri, pamwamba pake ndi mizere yowongoka (yomwe imatchedwanso chisanu) pambuyo pokonzedwa ndi kugwedezeka kwa makina pamwamba pa zitsulo zosapanga dzimbiri, kuphatikizapo kujambula kwa waya, ndi mizere ndi ma ripples.
Processing khalidwe muyezo: makulidwe a kapangidwe ndi yunifolomu ndi yunifolomu, kapangidwe mbali zonse za mankhwala ndi zachilengedwe ndi wokongola malinga ndi kapangidwe ndi zomangamanga zofunika, ndi kupindika malo mankhwala amaloledwa kukhala ndi pang'ono chipwirikiti kapangidwe kuti. sichimakhudza maonekedwe.
- Njira yojambulira:
(1) Njere zopangidwa ndi mitundu yosiyanasiyana ya sandpaper ndizosiyana.Kukula kwamtundu wa sandpaper, kuonda kwa njere, mbewuzo zimakhala zozama.M'malo mwake, sandpaper
Zing'onozing'ono zachitsanzo, mchenga udzakhala wokulirapo, umakhala wozama kwambiri.Choncho, chitsanzo cha sandpaper chiyenera kuwonetsedwa pa zojambula zaumisiri.
(2) Chojambula chawaya ndi cholozera: chiyenera kuwonetsedwa pa chojambula chojambula ngati chiri chowongoka kapena chopingasa waya (choyimiridwa ndi mivi iwiri).
(3) Chojambula chojambula chojambulacho sichiyenera kukhala ndi mbali zokwezera, mwinamwake zigawo zokwezeka zidzaphwanyidwa.
Zindikirani: Nthawi zambiri, mutatha kujambula waya, electroplating, oxidation, ndi zina zotero.Monga: plating yachitsulo, aluminium oxidation.Chifukwa cha zolakwika zamakina ojambulira mawaya, pakakhala mabowo akulu pazidutswa zing'onozing'ono zogwirira ntchito ndi zida zogwirira ntchito, kapangidwe kake ka jig kawaya kamayenera kuganiziridwa., kupewa khalidwe losauka la workpiece pambuyo kujambula waya.
- Waya kujambula makina ntchito ndi zodzitetezera
Asanajambule, makina ojambulira ayenera kusinthidwa mpaka kutalika koyenera malinga ndi makulidwe azinthuzo.
Liwiro la lamba wonyamula katundu likamachedwetsa, limathanso kugaya bwino kwambiri, ndipo mosiyana ndi ilo.Ngati kuya kwa chakudya ndi kwakukulu, pamwamba pa workpiece idzawotchedwa, kotero kuti chakudya chilichonse chisakhale chochuluka, chiyenera kukhala pafupifupi 0.05mm.
Ngati kupanikizika kwa silinda yosindikizira kuli kochepa kwambiri, chogwiritsira ntchito sichidzakanikizidwa mwamphamvu, ndipo workpiece idzaponyedwa kunja ndi mphamvu ya centrifugal ya wodzigudubuza.Ngati kupanikizika kuli kwakukulu, kukana kugaya kudzawonjezedwa ndipo zotsatira zakupera zidzakhudzidwa.Kujambula bwino kwa makina ojambulira waya sikudutsa 600mm.Ngati malangizowo ndi ochepera 600mm, muyenera kulabadira momwe mungayendere, chifukwa njira yojambulira ili m'mphepete mwa njira yodyetsera zinthu.
Kusamala pa pepala zitsulo zosapanga dzimbiri kupukuta zitsulo
Kuwala kwa chitsulo chosapanga dzimbiri pambuyo popukuta Poyang'anitsitsa, kuwala kwa malo opukutidwa a zigawozo kumagawidwa m'magulu a 5:
Gawo 1: Pali filimu yoyera ya oxide pamwamba, palibe kuwala;
Gawo 2: Kuwala pang'ono, autilainiyo singawoneke bwino;
Mzere wa 3: Kuwala kuli bwino, ndondomeko ikhoza kuwonedwa;
Kalasi 4: Pamwamba pake ndi yowala, ndipo ndondomekoyi ikuwoneka bwino (yofanana ndi khalidwe lapamwamba la electrochemical polishing);
Gawo 5: Kuwala ngati galasi.
Ambiri ndondomeko ya makina kupukuta ndi motere:
(1) Kuponya mwankhanza
Pambuyo mphero, EDM, kugaya ndi njira zina, pamwamba akhoza kupukutidwa ndi makina ozungulira pamwamba opukuta kapena makina opangira akupanga ndi liwiro lozungulira 35 000-40 000 rpm.Njira yomwe imagwiritsidwa ntchito kwambiri ndikugwiritsa ntchito gudumu lokhala ndi m'mimba mwake Φ 3mm ndi WA # 400 kuchotsa wosanjikiza woyera wa EDM.Ndiye pali pamanja akupera whetstone, kuchotsa whetstone ndi palafini monga mafuta kapena ozizira.Dongosolo la kagwiritsidwe ntchito ndi #180 ~ #240 ~ #320 ~ #400 ~ #600 ~ #800 ~ #1000.Oumba ambiri amasankha kuyamba ndi #400 kuti asunge nthawi.
(2) Kupukuta pang’ono
Kupukuta kwa semi-fine makamaka kumagwiritsa ntchito sandpaper ndi palafini.Manambala a sandpaper ndi: #400 ~ #600 ~ #800 ~ #1000 ~ #1200 ~ #1500.M'malo mwake, #1500 sandpaper ndiyoyenera kulimbitsa chitsulo chakufa (pamwamba pa 52HRC), osati chitsulo chowumitsidwa kale, chifukwa chingapangitse kuti pamwamba pa chitsulo cholimba chiwotchedwe.
(3) Kupukuta bwino
Kupukuta bwino kumagwiritsa ntchito phala la diamondi.Ngati mugwiritsa ntchito gudumu la nsalu yopukutira kusakaniza ufa wa diamondi kapena phala logaya pogaya, ndondomeko yopera yanthawi zonse ndi 9 μm (#1800) ~ 6 μm (#3000) ~ 3 μm (#8000).Phala la diamondi la 9 μm ndi gudumu lansalu lopukuta lingagwiritsidwe ntchito kuchotsa zizindikiro zatsitsi pa #1200 ndi #1500 sandpaper.Kenako pukuta ndi phala lomata ndi diamondi abrasive phala, mu dongosolo la 1 μm (#14000) ~ 1/2 μm (#60000) ~ 1/4 μm (#100000).Njira zopukutira zomwe zimafunikira kulondola pamwamba pa 1 μm (kuphatikiza 1 μm) zitha kuchitidwa muchipinda choyera chopukutira mu sitolo ya nkhungu.Kuti muyeretse bwino kwambiri, pafunika malo aukhondo.Fumbi, utsi, dandruff ndi madontho onse ali ndi kuthekera kosintha mawonekedwe opukutidwa bwino omwe mumapeza mukatha ntchito.
Kupukuta pamakina: Gwiritsani ntchito makina opukutira lamba kuti mupukutire chimango chodzigudubuza.Choyamba, gwiritsani ntchito lamba wa 120 # abrasive.Mtundu wa pamwamba ukafika poyambirira, sinthani lamba wa 240# abrasive.Mtundu wa pamwamba ukafika woyamba, sinthani lamba wa 800# abrasive.Mtundu wa pamwamba ukangofika, sinthani lamba wa 1200 #, ndiyeno muponyere ku mawonekedwe a mbale yokongoletsera yachitsulo chosapanga dzimbiri.
Kusamala pakupukuta zitsulo zosapanga dzimbiri
Kupukuta ndi sandpaper kapena lamba wa abrasive popera ndi ntchito yodula, kusiya mizere yabwino kwambiri pamwamba pa mbale yachitsulo.Pakhala pali zovuta ndi aluminiyamu ngati abrasive, mwina chifukwa cha zovuta.Zigawo zilizonse zowonongeka za zipangizo, monga malamba otsekemera ndi mawilo opera, siziyenera kugwiritsidwa ntchito pazinthu zina zosapanga dzimbiri musanagwiritse ntchito.Chifukwa izi zidzayipitsa pamwamba pazitsulo zosapanga dzimbiri.Pofuna kutsimikizira kuti pamwamba pake pamakhala kutha, gudumu kapena lamba watsopano ayenera kuyesedwa pazitsulo zomwezo kuti chitsanzo chomwecho chifanane.
Chitsulo chosapanga dzimbiri mawaya kujambula ndi kupukuta kuyendera muyezo
- Zinthu zowala zamagalasi osapanga dzimbiri
Pambuyo kupukuta kumalizidwa molingana ndi kupukuta ndi kupukuta, khalidwe loyenerera la pamwamba pa galasi lopangidwa ndi zitsulo zosapanga dzimbiri liyenera kuchitidwa molingana ndi Table 2;kuvomereza kutsika kudzachitika molingana ndi Table 3.
