Chokwadi chaicho chine nuanced; inzira yekutanga iyo, kana ichiitwa nemazvo uye nekunzwisisa, inokwikwidza munzvimbo dzausingatarisiri. Hakusi kungorasa simbi mugomba rejecha. Zviri pamusoro pekugadzirisa zvinosiyana-kuumbwa kwejecha, hunyoro, binder masisitimu, gating dhizaini, kusimba kwekudzora-inoparadzanisa inogona kushandiswa kukanda kubva kune chakaraswa chikamu. Ndakaona mapurojekiti akawanda achikundikana nekuti dhizaini yakakandwa pamusoro pemadziro kune imwe nheyo pasina kufunga nezve izvi zvakakosha. Sarudzo yemugadzirirwo kazhinji inowira pasi pakubata kwavo kweizvi zvinhu, kwete chete rondedzero yavo yemidziyo.
Mutiro weMaitiro: Zvose Zviri Mujecha
Ngatipindei mugrit. Chaizvoizvo. Iyo 'jecha' mukukanda jecha haisi yako yekuseri kwemba. Musanganiswa wakagadzirwa, unowanzo silika, zircon, kana chromite, wakabatanidzwa nevhu (jecha regirinhi) kana makemikari anosunga (sefuran kana phenolic resin yekusabikisa molds). Musiyano ndeweusiku nemasikati. Kune aluminium, ndinotsamira kune jecha rakasungwa nemakemikari kune yakaoma geometries kana kushivirira kwakasimba. Jecha regirini rinokurumidza uye rakachipa kune yakakwira-vhoriyamu, maumbirwo akareruka, asi unotengeserana nepamusoro pekupedzisira uye kugadzikana kwedimensional. Hunyanzvi huri pakusarudza hurongwa hwakakodzera hwebasa racho. Musungo wakajairika? Tichifunga kuti jecha rose rakafanana. Ndakave nezvikamu zvakabuda zvine inotyisa pamusoro peveining nekuti jecha rekuwedzera kupisa kwanga kusiri iko kwealuminium alloy's solidification pateni. Zvakatora mavhiki ekuedza uye kukanganisa nemagiredhi ejecha akasiyana uye binder ratios kuti zvigadziriswe.
Kugadzira mapeteni ndehumwe hunyanzvi husina kujeka. Mapateni ehuni akanakira prototypes kana mapfupi anomhanya, asi kune chero chinhu chinotsigirwa, unoda simbi kana epoxy mapatani. Iyo angle yekudhirowa, kupedzisa, mvumo yekuderera - imwe neimwe alloy inodonha pamwero wakasiyana - zvese zvinovakwa mune iyo pateni. Kukanganisa kwezvikamu zvishoma kubva muzana pa shrinkage kunogona kupa batch rese kunze kwekutsanangurwa. Ini ndinorangarira batch yepombi housings kwatakashandisa iyo yakajairwa shrinkage mutemo weA356 aluminium, asi iyo chaiyo shanduko uye tembiricha yekudururira yakaishandura zvakangoringana kuti ikonzeredze nyaya ine muchina mating chikamu. Taifanira kugadzirisa patani, inova chidzidzo chinodhura uye chinopedza nguva.
Ipapo kune gedhi nekusimuka. Apa ndipo panoratidza chiitiko chemuvambi. Uri kugadzira machani anodyisa aluminium yakanyungudutswa mugomba rekuumbwa uye madhirigi anodyisa shrinkage painotonhora. Kusakwana kwegeji kunotungamira kune mhirizhonga, izvo zvinokonzeresa oxide inclusions uye isina simba mavara. Kusakwana kusimuka kunotungamirira kune shrinkage porosity. Haisi dzidziso yemabhuku; Kunzwa kwakakudziridzwa kubva pakutarisa zviuru zveakadimburwa. Injiniya yakanaka yekuvamba dzimwe nguva inoisa diki yekusimudza uko iyo simulation software isingaratidze nyaya, yakavakirwa pahunch kubva kune rakafanana basa rakapfuura. Uye kazhinji vakarurama.
Iko Aluminium Jecha Kukanda Inokodzera (Uye kwaIsingaite)
Iyi nzira haisi yezvose. Kune yakakwirira-vhoriyamu, yakatetepa-madziro, yakaoma kunzwisisa senge turbine blades, iwe waizotarisa Investment casting kana kufa achikandwa. Asi kune yakaderera kusvika pakati mavhoriyamu, zvikamu zvakakura (funga mabhuroko einjini, makesi ekutapurirana, mabhuraketi makuru ezvimiro), uye uko kuchinjika kwedhizaini kwakakosha, kukanda jecha kunodhura zvakanyanya. Mutengo wekushandisa chikamu chidimbu chekukanda kufa. Iyo chaiyo inotapira nzvimbo ndeye-imwe-offs, prototypes, uye inorema-sectioned zvikamu.
