Kupanga nkhungu
Kufotokozera Kwachidule:
Kupanga nkhungu (Kufa kupanga) ndi njira yopangira zigawo zikuluzikulu malinga ndi kujambula kwa kapangidwe kake, pogwiritsa ntchito makina odulira, makina osokoneza bongo, chithandizo cham'mwamba ndi chithandizo cha kutentha, ndipo pomaliza amasonkhanitsa magawo onse kukhala nkhungu molingana ndi kapangidwe kamangidwe.
Kupanga nkhungu & kupanga ndi ntchito yofunikira kwambiri pamakampani amakono opanga. Imakhala ndi zida zofunikira pakuchita zazikulu, zogwirira ntchito bwino komanso kupanga mafakitale apamwamba.
Kodi nkhungu ndi chiyani?
Nkhungu (nkhungu, kufa) imadziwika kuti "mayi wa mafakitale", yomwe ndi njira yofunikira yopangira zida zapamwamba kwambiri, zogwira bwino komanso zopanga zazikulu pamakampani amakono opanga. Popanga makampani a nkhungu, nkhungu ndi zida zosiyanasiyana zimagwiritsidwa ntchito kupeza zinthu zofunika ndi jekeseni, kuwumba nkhonya, extrusion, kuponyera nkhungu kapena kulipira, smelting, stamping ndi njira zina. Mwachidule, nkhungu ndi chida chopangira zinthu. Chida ichi chimapangidwa ndi magawo osiyanasiyana, ndipo nkhungu zosiyanasiyana zimapangidwa ndi magawo osiyanasiyana. Zimazindikira makamaka kukonza kwa mawonekedwe a chinthucho posintha mawonekedwe akuthupi. Amadziwika kuti "mayi wamakampani".
Kodi kupanga nkhungu ndi chiyani?
Pafupifupi nkhungu zonse zimapangidwa ndi chitsulo, ndipo 90% zake ndizopangidwa ndi chitsulo.
Pogwiritsidwa ntchito ndi mphamvu zakunja, billet yachitsulo imakhala chida chopangira ndi mawonekedwe ndi kukula kwake. Amagwiritsidwa ntchito kwambiri pakupondaponda, kulipira nkhungu, mutu wozizira, extrusion, magawo azitsulo opondera, kukakamiza, komanso pulasitiki waukadaulo, labala, ziwiya zadothi ndi zinthu zina za kupanikizika kapena jekeseni. Nkhunguyo imakhala ndi mawonekedwe apakatikati kapena mawonekedwe amkati, ndipo chosowacho chitha kusiyanitsidwa molingana ndi mawonekedwe (osalemba) pogwiritsa ntchito mawonekedwewo m'mphepete mwake. Maonekedwe a mkatikati angagwiritsidwe ntchito kupeza mawonekedwe ofanana a billet. Nkhungu imaphatikizapo magawo awiri: nkhungu yosunthika ndi nkhungu zokhazikika (kapena nkhonya ndi nkhungu ya concave), yomwe imatha kupatulidwa ndikuphatikizidwa. Magawano akalekanitsidwa, zilembozo zimalowetsedwa munkhokwe kuti zipangidwe zikatsekedwa. Nkhungu ndi chida chenicheni chokhala ndi mawonekedwe ovuta komanso okhala ndi mphamvu ya billet. Ili ndi zofunikira kwambiri pakulimba kwamphamvu, kulimba, kuwuma kwapamwamba, kukhathamira kwapamwamba ndikukonzekera molondola. Kukula kwa kapangidwe ka nkhungu ndi chimodzi mwazinthu zofunikira kwambiri pamlingo wopanga makina.
Njira yopangira nkhungu imaphatikizapo: kapangidwe ka nkhungu, kukonza nkhungu, kuyendera nkhungu ndikuyesa mayeso, kusintha kwa nkhungu ndi kukonza, ndi kukonza nkhungu.
Kukonzekera kwa nkhungu kumawonekera nthawi zambiri kudzera pakulimbitsa, kudula, kutentha mankhwala ndi msonkhano ndi zina. Pofuna kutsimikizira kuti nkhunguyo ndi yopanda phindu komanso kuti ichepetse mtengo wopangira, zinthuzo zimayenera kukhala ndi kufooka kwabwino, kudula kosavuta, kuumitsa ndi kugaya, komanso kuyeneranso kukhala ndi makutidwe ndi okosijeni ang'onoang'ono, kuzindikira kwa decarbonization ndi kuzimitsa chizolowezi chokhotakhota. Kudula kumatenga 70% ya kuchuluka kwa magwiridwe antchito a nkhungu. Gawo lovuta kwambiri ndikutenga thumba lomwe limakwaniritsa zofunikira za mawonekedwe, kukula kwake ndi mawonekedwe ake, komanso njira zonse.
Nkhungu kupanga ndondomeko
Chitsulo chosapanga kanthu chopangira nkhungu chagudubuzika ndikupangidwa mu chitsulo, ndipo chomeracho chimatha kusankha kugula. Kupanga nkhungu ndikupanga izi zopanda zingwe zachitsulo kuti zizipanga zomwe zimatha kupanga zinthu zambiri. Kupanga kwa nkhungu kumaphatikizapo kapangidwe ka nkhungu, makina ndi kusonkhana kwa nkhungu pachimake ndi nkhungu.
1. Kupanga nkhungu kumamalizidwa ndi akatswiri akatswiri. Nkhungu kapangidwe ndi muyezo ndi maziko a kupanga lonse nkhungu. Malinga ndi zofunikira za kapangidwe kazinthu komanso mawonekedwe olondola, mawonekedwe a ntchito ndi zotulukapo zomwe zikuyembekezeredwa, komanso kasinthidwe kamakina akamaumba jekeseni, mainjiniya ayenera kusankha chitsulo chilichonse pagawo lankhungu ndikuzindikira kapangidwe kake ndi nkhungu. Kulingalira bwino kwa kapangidwe ka nkhungu kumatsimikizira kupanga zovuta, mtengo, moyo wautumiki, zokolola komanso mtundu wa zinthu za nkhungu.
Nkhungu ndi mtundu wa zida zodula. Pakapangidwe kake, mainjiniya athu amagwiritsa ntchito mapulogalamu kuti awunikire ndikuyerekeza kugawa kwa magawo, njira yolowera, malo opangira jekeseni komanso kapangidwe kake.
2. Makina a nkhungu. Nkhungu billet imakonzedwa ndi chida chamakina malinga ndi kapangidwe ndi kapangidwe kake kaukadaulo. Nthawi zambiri, zida zodulira makina ndi zida zomwe amagwiritsa ntchito popanga zisoti zimaphatikizapo CNC, EDM, WEDM, lathe, chopukusira, makina opukutira, ndi zina zotero zida zamakina zotsogola zimatha kusintha kwambiri kulondola kwa nkhungu, kufupikitsa kayendedwe kake ndikuchepetsa mtengo. Mitundu yosiyanasiyana ya nkhungu imagwiritsa ntchito makina osiyanasiyana: zida zopangira jekeseni ndi zida zopangira kufa nthawi zambiri zimagwiritsa ntchito CNC, EDM ndi WEDM. Mitundu ya nkhungu ndi extrusion amatha kugwiritsa ntchito CNC ndi WEDM
3. Msonkhano wa nkhungu. Kusonkhana kwa nkhungu kumadalira akatswiri. Zimaphatikizaponso kufa, kutsekemera, chitsogozo, njira yochotsera, kufanana pakati pa chimango ndi mota, msonkhano wothamanga, komanso gawo lomwe silingadulidwe, ndi msonkhano wonse womaliza. Kukwera kwachinyengo kwa makina, kuchepa kwa ntchito ya msonkhano wofera, kumachepetsa kozungulira ndikupanga mtengo wotsika. Pambuyo pomaliza msonkhano wa akufa, ndikofunikira kuyesa, kutsimikizira, kukonza ndikuwongolera mafawo mpaka atatulutsa zinthu zoyenera ndi zina zambiri.

Kampani ya Mestech imagwira ntchito yopanga nkhungu za pulasitiki ndi jekeseni wa mankhwala, komanso amatha kuumba zida zakuthupi (kufa kufa-kuponyera kufa, kupondaponda kufa) kupanga ndi kupanga zida zazitsulo.
