Kodi maubwino a mineral casting marble machining center ndi chiyani?
Ma mineral castings (opangidwa ndi anthu opangidwa ndi granite aka resin konkire) akhala akuvomerezedwa kwambiri mumakampani opanga zida zamakina kwazaka zopitilira 30 ngati zinthu zomangika.

Malinga ndi ziwerengero, ku Europe, chimodzi mwa zida 10 zilizonse zamakina zimagwiritsa ntchito miyala ngati bedi.Komabe, kugwiritsa ntchito chidziwitso chosayenera, chidziwitso chosakwanira kapena cholakwika kungayambitse kukayikira ndi tsankho motsutsana ndi Mineral Castings.Choncho, popanga zipangizo zatsopano, m'pofunika kufufuza ubwino ndi zovuta za mineral castings ndikuziyerekezera ndi zipangizo zina.

Pansi pamakina omangira nthawi zambiri amagawidwa kukhala chitsulo choponyedwa, kuponya mchere (polima ndi/kapena konkire ya resin), chitsulo / chotchinga (grouting/non-grouting) ndi miyala yachilengedwe (monga granite).Chilichonse chili ndi mawonekedwe ake, ndipo palibe chomangira changwiro.Pokhapokha poyang'ana ubwino ndi kuipa kwa zinthuzo malinga ndi zofunikira zenizeni zapangidwe, zikhoza kusankhidwa bwino.

Ntchito ziwiri zofunika kwambiri zamapangidwe - zimatsimikizira mayamwidwe a geometry, malo ndi mphamvu za zigawo, motsatana zimayika zofunikira pakuchita (static, dynamic and thermal performance), magwiridwe antchito / kapangidwe kake (kulondola, kulemera, makulidwe a khoma, kumasuka kwa njanji zowongolera) pakuyika zida, makina osindikizira atolankhani, mayendedwe) ndi zofunikira zamtengo (mtengo, kuchuluka, kupezeka, mawonekedwe adongosolo).
I. Zofunikira pazantchito zamapangidwe

1. Makhalidwe osasunthika

Muyeso woyezera momwe zinthu ziliri pa maziko nthawi zambiri ndi kuuma kwa zinthu - kusinthika kochepa pansi pa katundu, osati mphamvu zambiri.Pamapindika osasunthika, ma mineral castings angaganizidwe ngati isotropic homogeneous materials kumvera lamulo la Hooke.

Kachulukidwe ndi zotanuka modulus ya mineral castings motsatana ndi 1/3 ya chitsulo chotayidwa.Popeza ma mineral castings ndi zitsulo zotayidwa zimakhala ndi kuuma kwapadera komweko, pansi pa kulemera komweko, kukhazikika kwazitsulo zachitsulo ndi kuponyedwa kwa mchere kumakhala kofanana popanda kuganizira kukhudzidwa kwa mawonekedwe.Nthawi zambiri, makulidwe a khoma la makulidwe a mineral castings nthawi zambiri amakhala 3 kuwirikiza kwa chitsulo, ndipo kapangidwe kameneka sikungayambitse vuto lililonse pamakina azinthu kapena kuponyera.Zopangira mchere ndizoyenera kugwirira ntchito pamalo osasunthika omwe amanyamula kupanikizika (monga mabedi, zogwiriziza, mizati) ndipo sizoyenera ngati mafelemu opyapyala komanso/kapena mafelemu ang'onoang'ono (monga matebulo, mapaleti, zosinthira zida, ngolo, zothandizira zopota).Kulemera kwa magawo omangika nthawi zambiri kumachepetsedwa ndi zida za opanga ma mineral cast, ndipo zinthu zopangira mchere pamwamba pa matani 15 nthawi zambiri zimakhala zosowa.

2. Makhalidwe amphamvu

Kuthamanga kwakukulu kozungulira komanso / kapena kuthamanga kwa shaft, ndikofunikira kwambiri kuti makinawo azigwira ntchito mwamphamvu.Kuyika mwachangu, kusinthira zida mwachangu, komanso chakudya chothamanga kwambiri kumalimbitsa kumveka kwamakina ndi chisangalalo champhamvu cha magawo a makina.Kuphatikiza pa kapangidwe ka gawo la gawoli, kupotoza, kugawa kwakukulu, ndi kuuma kwamphamvu kwa gawoli kumakhudzidwa kwambiri ndi kunyowa kwa zinthuzo.

Kugwiritsa ntchito mineral castings kumapereka njira yabwino yothetsera mavutowa.Chifukwa imatenga kugwedezeka ka 10 kuposa chitsulo chachikhalidwe, imatha kuchepetsa matalikidwe ndi ma frequency achilengedwe.

M'machitidwe opangira makina monga makina, amatha kubweretsa kulondola kwambiri, mawonekedwe abwino a pamwamba, komanso moyo wautali wa zida.Panthawi imodzimodziyo, pokhudzana ndi phokoso la phokoso, ma mineral castings adachitanso bwino poyerekezera ndi kutsimikiziranso zapansi, ma transmission castings ndi zipangizo zosiyanasiyana za injini zazikulu ndi ma centrifuges.Malinga ndi kusanthula kwamphamvu kwa mawu, kuponya kwa mchere kumatha kuchepetsedwa ndi 20% pamlingo wamphamvu wamawu.

3. Thermal katundu

Akatswiri amayerekeza kuti pafupifupi 80% yapatuka kwa zida zamakina kumachitika chifukwa cha kutentha.Kusokoneza ndondomeko monga magwero a kutentha kwa mkati kapena kunja, kutentha, kusintha kwa workpieces, ndi zina zotero ndizo zimayambitsa kutentha kwa kutentha.Kuti muthe kusankha zinthu zabwino kwambiri, m'pofunika kufotokozera zofunikira zakuthupi.Kutentha kwapadera komanso kutsika kwamafuta kumapangitsa kuti mchere uzikhala ndi kutentha kwanthawi yayitali (monga kusintha kwa zida zogwirira ntchito) komanso kusinthasintha kwa kutentha kwapakati.Ngati kutentha kwachangu kumafunika ngati bedi lachitsulo kapena kutentha kwa bedi ndikoletsedwa, zida zotenthetsera kapena zoziziritsa zitha kuponyedwa mwachindunji muzoponya zamchere kuti ziwongolere kutentha.Kugwiritsa ntchito mtundu uwu wa chipangizo cholipirira kutentha kumatha kuchepetsa kupindika komwe kumachitika chifukwa cha kutentha, komwe kumathandiza kuwongolera kulondola pamtengo wokwanira.

II.Zofunikira pakugwirira ntchito komanso kapangidwe kake

Umphumphu ndi chinthu chosiyanitsa chomwe chimasiyanitsa mineral castings ndi zipangizo zina.Kutentha kwakukulu kwa kuponyera kwa mineral castings ndi 45 ° C, ndipo pamodzi ndi nkhungu zapamwamba kwambiri ndi zida, zigawo ndi mineral castings zikhoza kuponyedwa palimodzi.

Njira zopangiranso zaukadaulo zitha kugwiritsidwanso ntchito pazosowa zopangira mchere, zomwe zimapangitsa kuti pakhale malo okwera bwino ndi njanji omwe safunikira makina.Monga zida zina zoyambira, ma mineral castings amatsatiridwa ndi malamulo enaake apangidwe.Makulidwe a khoma, zida zonyamula katundu, zoyika nthiti, kutsitsa ndi kutsitsa njira zonse ndizosiyana ndi zida zina mpaka pamlingo wina, ndipo ziyenera kuganiziridwa pasadakhale pakukonza.

III.Zofunika mtengo

Ngakhale kuli kofunika kulingalira kuchokera ku luso lamakono, kugwiritsira ntchito ndalama kumawonetsa kufunikira kwake.Kugwiritsa ntchito ma mineral castings kumathandizira mainjiniya kuti asunge ndalama zambiri zopangira ndikugwiritsa ntchito.Kuphatikiza pa kupulumutsa pamitengo yamakina, kuponyera, kusonkhanitsa komaliza, ndi kuonjezera ndalama zogulira zinthu (zosungiramo katundu ndi zoyendera) zonse zimachepetsedwa moyenerera.Poganizira ntchito yapamwamba ya mineral castings, iyenera kuwonedwa ngati ntchito yonse.M'malo mwake, ndizomveka kupanga kufananitsa kwamtengo pomwe mazikowo adayikidwa kapena kukhazikitsidwa kale.Mtengo woyambira wokwera kwambiri ndi mtengo wa nkhungu zoponyera mchere ndi zida, koma mtengowu ukhoza kuchepetsedwa mukugwiritsa ntchito nthawi yayitali (500-1000 zidutswa / nkhungu zachitsulo), ndipo kugwiritsidwa ntchito kwapachaka kumakhala pafupifupi 10-15 zidutswa.

IV.Kuchuluka kwa ntchito

Monga zida zomangika, ma mineral castings akusintha nthawi zonse zida zamapangidwe, ndipo chinsinsi chakukula kwake mwachangu chimakhala pakuponyedwa kwa mchere, nkhungu, ndi zomangira zokhazikika.Pakalipano, kuponyedwa kwa mchere kumagwiritsidwa ntchito kwambiri m'madera ambiri a zida zamakina monga makina opera ndi makina othamanga kwambiri.Opanga makina opera akhala apainiya m'gawo la zida zamakina pogwiritsa ntchito ma mineral castings pamabedi amakina.Mwachitsanzo, makampani odziwika padziko lonse lapansi monga ABA z&b, Bahmler, Jung, Mikrosa, Schaudt, Stude, etc. akhala akupindula ndi kunyowetsa, kutentha kwa kutentha komanso kukhulupirika kwa ma mineral castings kuti apeze kulondola kwambiri komanso khalidwe labwino kwambiri lapamwamba pogaya. .

Ndi katundu wochulukirachulukira nthawi zonse, kuponyedwa kwa mchere kumakondedwanso kwambiri ndi makampani otsogola padziko lonse lapansi pantchito yopukusira zida.Bedi la mineral casting limakhala lolimba kwambiri ndipo limatha kuthetsa mphamvu yomwe imabwera chifukwa cha mathamangitsidwe amtundu wamoto.Nthawi yomweyo, kuphatikiza kwachilengedwe kwa magwiridwe antchito abwino a kugwedera ndi mota ya liniya kumatha kusintha kwambiri mawonekedwe amtundu wa workpiece ndi moyo wautumiki wa gudumu lopera.
