Abstract

Ovaj rad opisuje postupak tlačnog lijevanja poklopca diferencijalnog prijenosnika. Kratak uvod povezuje automobilsku i ljevačku industriju, te predstavlja koncept diferencijalnog prijenosa. Objašnjeni su postupci lijevanja i pripreme kalupa, a posebno je pobliže objašnjen postupak tlačnog lijeva i izvedbe strojeva koje se primjenjuju u procesu. Definirani su tehnološki parametri koji imaju utjecaj na svojstva odljevka, kao i na sam proces lijevanja. Nadalje su nabrojani materijali koji se... More koriste za proizvodnju legura za tlačni lijev, ponajviše aluminijskih. Također su dočarane greške koje se mogu pojaviti u tlačnim odljevcima. Nadalje, sažet je razvoj trodimenzionalnog skeniranja te je opisano lasersko skeniranje i rekonstrukcija modela. Eksperimentalni dio prikazuje izradu CAD modela upotrebom 3D skenera i povezivanje s uljevnim sustavom i preljevima. Pokazuje se točnost izrađenog modela usporedbom mase sa stvarnim predmetom. Simulacija lijevanja poklopca izvedena je u programskom paketu ProCAST, te je napravljena detaljna analiza odljevka. Less

Abstract (english)

This thesis describes the process of pressure die casting of differential cover. Short introduction connects the car industry with the casting industry while also describes the bare concept of differential. Thesis describes the process of casting and mold preparation as well and it describes the pressure die casting in more detail. The machines used in the process of pressure die casting are also mentioned. Technological parameters which influence the cast and the casting process are... More defined as well. Materials used in alloy production for pressure die casting are named next (mostly aluminum). Further more, mistakes and errors which can occur in the pressure die casting are mention as well. The development of 3D scans, laser scans and model reconstruction i salso described. Experimental part shows how the CAD models were made by using 3D scanner and how it was applied in casting. Next is the mass comparison of the model and real object. Pressure die casting of differential cover was made in ProCAST computer software and last but not least the detailed analysis of the cast was made. Less
