Kuponya ndalama, komwe kumadziwikanso kuti kutaya sera, kudapangidwa zaka 5,000 zapitazo.Njira yoponyera iyi imapereka magawo olondola, obwerezabwereza komanso osunthika okhala ndi zitsulo zosiyanasiyana komanso ma alloys apamwamba kwambiri.Njira yoponyera iyi ndi yoyenera kuponyera fungo ndi magawo olondola ndipo ndiyokwera mtengo kuposa njira zina zoponyera.Ndi kupanga kwakukulu, mtengo wa unit udzatsika.
Njira yopangira Investment:
Kupanga Zitsanzo za Sera: Opanga ndalama akuyenera kupanga mapangidwe a sera opangira sera.Njira zambiri zopangira ndalama zimafunikira ma wax apamwamba kwambiri kuti amalize sitepe iyi.
Kusonkhanitsa mtengo wa sera: Mtengo wopangira chinthu chimodzi chopangira ndalama ndi wokwera, ndipo posonkhanitsa mitengo ya sera, opanga ndalama amatha kupanga zokolola zambiri.
Kupanga zipolopolo: Pangani matumba a zipolopolo pamitengo ya sera, alimbitseni ndikugwiritsanso ntchito poponya motsatira.
Kuchotsa Sera: Kuchotsa sera mkatimo kukupatsani mpata wothira zitsulo zosungunuka mubokosi lomalizidwa.
Kugwetsa chipolopolo: Chitsulo chikalimba, chotsa chipolopolocho kuti mutenge mtengo wopangira zitsulo.Dulani iwo pamtengo ndipo mudzakhala ndi chomaliza chopangira ndalama.
Zaukadaulo:
1. Kulondola kwapamwamba kwambiri ndi kulondola kwa geometric;
2. Kukhwimitsa kwakukulu pamwamba;
3. Ikhoza kuponyera ma castings ndi mawonekedwe ovuta, ndipo ma alloys omwe amaponyedwa alibe malire.
Zoipa: ndondomeko yovuta komanso yokwera mtengo
Kugwiritsa ntchito: koyenera kupanga magawo ang'onoang'ono okhala ndi mawonekedwe ovuta, zofunikira zolondola kwambiri, kapena zovuta kuchita zinthu zina, monga masamba a injini ya turbine, etc.
1. Imatha kuponya ma castings ovuta amitundu yosiyanasiyana, makamaka ma superalloy castings.Mwachitsanzo, mawonekedwe akunja owongolera komanso kuzizira kwamkati kwa tsamba la injini ya jet sikungapangidwe ndi makina opangira.Kupanga kwaukadaulo wa Investment casting I sikungangokwaniritsa kupanga kwakukulu, kuwonetsetsa kusasinthika kwa kuponyera, komanso kupewa kupsinjika kwa mizere yotsalira pambuyo pokonza.
2. Kulondola kwadongosolo lazinthu zopangira ndalama ndizokwera kwambiri, nthawi zambiri mpaka CT4-6 (CT10~13 poponya mchenga ndi CT5~7 poponya).Inde, chifukwa cha zovuta za ndondomeko yopangira ndalama, pali zinthu zambiri zomwe zimakhudza kulondola kwazithunzi, monga kuchepa kwa nkhungu, kusinthika kwa nkhungu ya ndalama, kusintha kwa mzere wa chipolopolo cha nkhungu pa nthawi ya Kutentha ndi kuziziritsa ndondomeko, kuchepa kwa golide ndi mapindikidwe a kuponyera panthawi ya solidification, kulondola kwapadera kwazinthu zowonongeka zowonongeka ndizokwera kwambiri, komabe, kusasinthasintha kwake kumafunikabe kukonzedwanso (kusakanikirana kwapadera kwa castings ndi sing'anga ndi mkulu. sera ya kutentha iyenera kusinthidwa kwambiri)
3. Mukakanikiza nkhungu yopangira ndalama, nkhungu yokhala ndi mapeto apamwamba a nkhungu imagwiritsidwa ntchito.Choncho, mapeto a nkhungu ya ndalama ndi yokwera kwambiri.Kuphatikiza apo, chipolopolo cha nkhungucho chimapangidwa ndi zokutira zosagwira moto zopangidwa ndi zomatira zamphamvu kwambiri komanso zopinga, zomwe zimakutidwa ndi nkhungu yandalama.Pamwamba mapeto a nkhungu patsekeke mwachindunji kukhudzana ndi chitsulo chosungunuka ndi mkulu.Chifukwa chake, kutsirizira kwapang'onopang'ono kwa ndalama zopangira ndalama ndikwapamwamba kuposa kuponya wamba, nthawi zambiri mpaka Ra.1.3.2 μ m.
4. Ubwino waukulu wa kuponya ndalama ndikuti chifukwa kuponya ndalama kumakhala ndi zolondola kwambiri komanso kutha kwa pamwamba, kumatha kuchepetsa ntchito yopangira makina.Kuchepa kochepa chabe kwa machining allowance kungasiyidwe ku magawo omwe ali ndi zofunika kwambiri, ndipo ngakhale ma castings ena angagwiritsidwe ntchito popanda kukonza makina.Tingaone kuti ndalama kuponyera njira angapulumutse zambiri zida makina ndi processing nthawi, ndi kupulumutsa kwambiri zitsulo zopangira.
