Drop forging of hub
Hrbáček, Emil ; Žák, Ladislav (referee) ; Štroner, Marek (advisor)
Bachelor thesis presents a proposal technology of hub made of steel 15 321. Based on the literature study of the die forging was designed manufacturing process . Given the complexity of forging , the forging will be carried out in three operations. For these operations was calculated forging force and then selected vertical forging press LMZ 1600A (manufacturer Šmeral Brno a.s.) with a nominal forming force of 16 MN. Forging dies are made of steel 19 552 and heat treated according to drawings.

A Project for the production of the transmission case for the winch
Hrbáček, Emil ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
The project elaborated within engineering studies. The project is submitting design of technology production of precise holes for rolling bearings which are located in transmission case for the winch. Variants of production technologies were designed based on the construction drawings of transmission case. Chosen type of technology is boring. Boring was performed on the CNC machine DMF 180 produced by DMG MORI. DMF 180 allows precise production of bearings holes. Via selected criteria, it was selected the better variant of two. The criteria were: cylindricality, cohesiveness, position of elements and surface quality.
