Method development of forged piece in conditions of modern forge
Vraštiak, Michal ; Psík, Eduard (referee) ; Podaný, Kamil (advisor)
Taking into account modern technology solutions has been selected die forging of the wheel hub of automobile steel 14220 (DIN 16MnCr5) about the serial 50000 pcs. Based on the literature study and practical experience has been solved forging process, including technological calculations, engineering drawings and results of simulations of the forging process performed by the Qform software tool. A tool was designed to be made of 19552 grade alloy tool steel. The forged piece is to be forged on an LZK 1000 crank press with the nominal forming force of 10 MN manufactured by Šmeral Brno. The stock is divided with shears from bar 45 mm 6 m long to bar 89.5 mm long.

Uses of a cutting die in the manufacturing process
Důrek, Milan ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The bachelor’s thesis elaborated as part of a bachelor's degree of the branch mechanical engineering submitted a proposal of use cutting technology in the manufacturing process. The specified component is a tine and it is made of abrasion resistant and high-strength steel. The tine is produced in a series of 200,000 units / year. The first part of the thesis is pointed to technology of material cutting. For this technology a literature summary was made including a description of the requirements for the calculation of shearing machines and tools. In the second part, cutting tool was chosen based on technological calculations. For this instrument has been chosen crank press LKJA 1000 with a nominal force of 10 000 kN. The study evaluate the economic comparison of laser and cutting tool.

Production of gear
Svozilová, Lucie ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated design of technology production of the spur bevel gear, which is made of a steel rod from material 12 050. Pursuant to of the literary pursuit and calculation is designed as a threeoperational forging in an open die with using of ejector. Forging is realised in the vertical crank press LZK 1600 P/SH, with forming force 16 MN. Shearing and punching is performed in the shear press LKOA 200. Forging dies are produced from alloyed instrumental steel 19 556 heat-worked according to drawing documentation.
