Abstract
Tato bakalářská práce se zabývá technologií výroby odlitku vzduchového regulátoru vysokotlakého kompresoru, geometrií a úpravou formy za účelem eliminace vnitřních vad. Byla provedena analýza stávajícího procesu výroby ve slévárně Alumetall CZ s.r.o., při které byly zjištěny základní technologické parametry, které následně sloužily společně s CAD modelem formy jako vstupní hodnoty do simulačního programu MAGMAsoft?. Na základě vyhodnocení vad stávajících odlitků byly s využitím simulace plnění a tuhnutí odlitku navrženy změny geometrie formy s cílem snížit výskyt vad. U finální verze byla v simulačním programu provedena optimalizace teploty taveniny a obsahu křemíku. Vybrané návrhy řešení byly doporučeny firmě Alumetall k realizaci.
This bachelor thesis deals with the technology of production of the high-pressure air regulator casting, mould geometry and modification in order to eliminate internal defects. An analysis of the existing production process in the Alumetall CZ s.r.o. foundry was carried out, during which basic technological parameters were identified, which subsequently served together with the CAD model of the mould as input values to the MAGMAsoft? simulation program. Based on the evaluation of defects in existing castings, changes to the mould geometry were proposed to reduce the occurrence of defects using the simulation of filling and solidification of the casting. For the final version, the melt temperature and silicon content were optimized in the simulation program. The selected solution designs were recommended to Alumetall for implementation.
