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.

Surface treatment of selected steels using electron beam
Oríšek, Petr ; Jan, Vít (referee) ; Kouřil, Miloslav (advisor)
The thesis aims for the surface treatment of materials using electron beam. It includes a literary research describing physical principle and properties of the electron beam. This research also presents possible influencing of the beam and describes the construction of the device that generates the beam. Various applications of the electron beam for the material treatment are presented in the second part of the paper. Within this thesis an experiment with the heat treatment of the steel surface by the electron beam has been realized. The experiment was aimed at creating a layer as deep as possible without melting the surface. The results and their evaluation are presented in the experimental part of the thesis. The attention is also paid to selected process parameters.

Drop forging of gear wheel
Bednařík, Petr ; Lidmila, Zdeněk (referee) ; Štroner, Marek (advisor)
The project elaborated design of technology production of gear wheel from circular blanks of steel 12 050. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process. Dies proposal will be based on relevant standards, materials die steel will be 19 552. Given the complexity of the shape and dimensions of the gear will be used in three operations. Based on the calculated forging force was chosen vertical forging sheet LMZ 1600 A/S with a nominal power of 16 MN. Due to the use of the press die is provided with an ejector.
