Abstract

U diplomskom radu odrađen je zadatak konstruiranja kalupa za tlačni lijev spojnice za stlačeni zrak od aluminijeve legure primjenom reverzibilnog inženjerstva. Na početku rada u teorijskom dijelu objašnjeno je što podrazumijeva pojam alatničarstvo te koja su znanja potrebna za uspješnu izradu kalupa za tlačni lijev. Nakon toga iznesen je teorijski pregled lijevanja pod tlakom te teorijski pregled reverzibilnog inženjerstva u strojarskoj primjeni. Zatim je obrađena analiza odljevka za koji je potrebno konstruirati kalup za tlačni lijev te je prikazan postupak dobivanja CAD modela spojnice za stlačeni zrak. Nakon analize odljevka napravljen je inicijalni proračun prema kojemu su generirani koncepti uljevnog sustava. Zatim je napravljena analiza i simulacija lijevanja za svaki koncept uljevnog sustava te je odabran najbolji. Nakon provedene razrade odabranog koncepta prikazan je postupak dobivanja kalupa za tlačni lijev spojnice. Najvažniji rezultat rada je prijedlog konstrukcije kalupa za tlačni lijev spojnice .

Abstract (english)

In this master thesis, the task of constructing a die casting mould for a compressed air coupling made of aluminium alloy was completed using reversible engineering. At the beginning of the thesis, in the theoretical part, it was explained what the term toolmaking implies and what knowledge is needed for the successful production of high pressure die casting moulds. After that, a theoretical overview of high pressure die casting and a theoretical overview of reversible engineering in mechanical applications were presented. Then, the analysis of the casting for which it is necessary to construct a mould was processed, and the process of obtaining a CAD model of the compressed air coupling was presented. After the analysis of the casting, an initial calculation was made according to which the concepts of gating systems were generated. Then the analysis and casting simulation for each gating system concept was made and the best one was selected. After the elaboration of the selected concept, the process of obtaining the mould for high pressure die casting of the coupling was presented. The most important result of the work is the proposal for the construction of the mould for high pressure die casting of the aluminium alloy coupling.
