Inzvimbo isingagone kutaurirana.
Datum Kuvhima: Yekutanga uye Yakanyanya Kukosha Cheka
Ichi chinogona kunge chiri chikamu chisinganyanyo kurukurwa nezvacho precision casting machining. Kumisikidza ako ekutanga madhamu pane yakaomeswa casting inyanzvi. Iwe haugone kufungidzira chero chinhu. Iyo inoratidzika kunge yakati sandara flange? Kunenge kwakakotamiswa. Iwo mabhegi maviri akagadzirirwa kurongeka? Hazvina kunyatsoenderana. Iwe unofanirwa kuwana chikamu mumuchina wekubatanidza system nenzira inoderedza huwandu hwezvinhu zvaunoda kubvisa kuti ugadzire ako echokwadi, akagadzirwa datums.
Isu tinowanzo shandisa maitiro ekuongorora paCNC kuburitsa makiyi nzvimbo isati yachekwa yekutanga. Inguva pamushini, asi inochengetedza zvimedu. Iwe unorega chirongwa ichi kuwana yakanakisa-yakakodzera ndege kana yepakati peiyo rough bore, uye ipapo inoshandura iyo coordination system saizvozvo. Dzimwe nguva, kune ekupedzisira-yepamusoro-chaizvo zvikamu, isu tichatoita pre-machining kushushikana kushushikana. Tora chidimbu chechiedza kuti ugadzire datum yenguva pfupi, wozotumira chikamu kunze kwekuchovha bhasikoro kuchizorodza, wozochidzosa uye womisazve dhamu kubva panzvimbo yakagadzirwa nemichina. Kurwadza, asi kune zvikamu zvinobata kushivirira pasi pe0.02mm, kazhinji ndiyo nzira chete.
Ndakaona mhinduro dzakareruka, dzakanaka zvakare. Kumhuri yezvitsigiro zvesimbi, muvambi (mufambidzani akafanana neQSY munzira yavo yakabatanidzwa) akatanga kukanda mumapedhi madiki, akasimudzwa panzvimbo dzisiri dzakakosha. Aya mapadhi akagadzirwa kuti anyatsoenderana muforoma. Kuvhiya kwedu kwekutanga kwaive kutarisana nechigayo aya mapadhi matatu kugadzira dombo-rakasimba, kinematic mounting fixture kune ese aitevera maoparesheni. Yakanga iri yekudyidzana dhizaini shanduko yakachengetedza maawa ekuseta uye yekuongorora nguva. Ndiyo synergy yaunoda.
Kana Zvinhu Zvikashata: Porosity, Shifts, uye Salvage Ops
Hakusi kuumbwa kwese kwakakwana. Iyo machining pasi ndiro gedhi remhando yekupedzisira. Iwe unenge uchitora kucheka uye wobva waona gomba diki re porosity richioneka. Mubvunzo ndewokuti: zvinogamuchirwa here? Maererano neASTM standard, pamwe. Nokuda kwebasa rechikamu? Ndiko kufona kwekutonga kweinjiniya. Dzimwe nguva unogona kuzvisanganisa. Dzimwe nguva, iri munzvimbo yakakosha yekuisa chisimbiso, uye chikamu chacho chikara. Kuve nemachining mukati-mumba zvinoreva kuti iyi sarudzo inogona kuitwa mumaminitsi, neinjiniya yekukanda ipapo kuti iongorore, kwete mumavhiki kuburikidza neemail mumakondinendi.
Dambudziko rinonyanya kujeka ndeye core shift. Iyo yemukati ceramic musimboti inofamba zvishoma panguva yekudurura, zvichiita kuti madziro ave matete kune rimwe divi pane akagadzirwa. Iwe unoona izvi paunenge uchigadzira bore uye iwe unopaza usingafungire. Iko hakuna salvage kune izvozvo. Iyo chete inogadzirisa iri nani process control mune foundry. Apa ndipo zvakare apo kushanda kwakabatanidzwa kunoratidza kukosha kwayo. Chikwata chekugadzira chinopa nekukurumidza, mhinduro yemuviri-Takave nekuputika-kuburikidza pabatch XYZ pazasi flange-uye timu yekukanda inogona kudzokera kumashure inotarisa yavo yepakati kuseta maitiro eiyo mold. Inovhara loop nekukurumidza.
Takambova nekumhanya kwedzimba huru dzesimbi dzisina simbi uko chikamu chimwe nechimwe chairatidza hunyoro hudiki munzvimbo imwechete mushure mekupera. Yaive yakanaka, asi mutengi aisazvigamuchira. Panzvimbo pekuvarasa, takashanda nenyanzvi yewelding iyo yaigona kugadzirisa micro-TIG, tobva tagadzirazve nharaunda yenzvimbo. Kwakanga kuchidhura kugadzirazve, asi kwakachengetedza zvikamu. Chidzidzo chaive chekugadzirisa dhizaini yekusimudza pakuisa kwemaodha emangwana. Iyo machining process yakaona chikanganiso chekukanda, uye mhinduro yakashandiswa kumusoro kwerwizi.
The Finish Line: Kupfuura Ra chete
Kupedzwa kwepamusoro pamuchina wakakandwa haingori nhamba yeRa. Ndezvekuperera kwechiso. Kune zvikamu zviri pasi pekuneta, senge turbine blades kana magiya ekumhara, machining maitiro haafanire kusimudzira madiki-diki kana kushushikana kushushikana. Izvi zvinowanzoreva kudzorwa, zvinyoro zvekupedzisa kupfuura, dzimwe nguva zvinoteverwa nematanho akaita senge kupfura peening kana kukudza. Iyo as-cast ganda rinowanzo kubviswa zvachose munzvimbo dzakaoma nekuti rinogona kuve nekushomeka oxidation kana inclusions.
Zvadaro pane dimensional kugadzikana. Iyo hombe, yakaoma yekukandira inogadzirwa kune rimwe divi inogona kuchinjika paunenge uchiburitsa kushushikana kwemukati nekubvisa zvinhu. Dzimwe nguva iwe unofanirwa kuchina mumatanho, uchitenderedza chikamu uye kubvisa zvinhu symmetrically kuenzanisa kuburitswa kwekushushikana. Kutamba. Hausi kungocheka kuita chimiro; uri kutonga mamiriro ekushushikana kwechikamu mukati mekuita. Ini ndinorangarira hombe giya kesi kwataifanira rough muchina zvese, kuitumira kune vibration kusagadzikana, tozodzoka kunopedzisa machining. Kusvetuka danho iroro kungadai kwakaguma nezvikamu zvichienda kunze kwekushivirira mumunda.
Pakupedzisira, precision casting machining ndiro zambuko pakati pezvinogoneka uye chikamu chinoshanda. Inoda ruremekedzo rwekukandira kwakauya pamberi payo. Haisi yekusagadzikana, otomatiki oparesheni. Zvinoda kutonga, ruzivo, uye kazhinji, mutsara wakananga kumashure kune yekutanga pasi. Uchitarisa kugona kwekambani, iwe unoda kuona kuti ivo vanonzwisisa inoenderera mberi, kubva kune yakanyungudutswa alloy kusvika kune yekupedzisira deburred edge. Ndizvo zvinoshandura padhuze-neti-chimiro kuita mambure-kubudirira chikamu.
