Manufacturing of a Segment of the Seat Positioning System
Horák, Jan ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis is focused on the design of technology for the production of a seat positioning system made of sheet steel ČSN 11 373 with a thickness of 2 mm. Due to the adjustment of the production quantity of 200 000 pieces per year, the required dimensional accuracy and surface quality of the cutting surface is used by the technology of production of fine blanking with a pressure edge. Part of the work is the implementation of technological and construction calculations, including the design of the cutting tool with the necessary drawing documentation. An alternating arrangement of cut-outs for a coiled sheet metal blank (Ds = 1 200 mm, ds = 500 mm) is chosen as most suitable in the work, which means the use of 36 coils for a given annual production. In the final part of the work, a three-acting hydraulic press Feintool HFA 8800plus is chosen for the production of the component, which is incorporated into the automated production line FBA 6/300, including all necessary equipment for handling, unwinding and straightening the cut sheet metal strip.

Manufacturing of dice
Doušek, Martin ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The advertising (playing) dice is used for playing games and concurrently as promotional device to showing up company in the process of transfer events in full view of the public. The element is made of a structural steel 11 373, the production series are 5000 units per year. Produced component has a lenght of 220 mm, a width of 165 mm and a thickness of 1,5 mm. The variant solution was as optimal technology selected combination of rolling cutting followed by three folds in three separate instruments. It were made technological and structural calculations of which were devised tools, for which was made a basic drawing documentation. For production from total deformation force was chosen eccentric press S 250 with rated energy 2 500 kN. In the next step were fixed costs to produce one piece with the production of a advertising dice with energy, wages and material is 12,75 CZK.

Manufacturing of start segment by fineblanking technology
Tichoň, Ondřej ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The thesis deals with the design of the manufacturing technology of the starting segment, which is used to transmit the torque from the starting lever of the motorcycle. The part is made of steel 11 373 in the form of a sheet with a thickness of 6 mm, and the production series is set at 60,000 pieces per year. As part of the thesis, an innovation was proposed, which consists of cold pressing the shaft into the hole, and thereby eliminating the associated welding operation, speeding up production and making it more precise. Due to the required precision and the size of the series, a fine blanking was chosen for the production of the starting segment. Furthermore, coils of sheet metal were chosen as a semi-finished product, while 19 coils with a diameter of 1400 mm and one incomplete coil with a diameter of 1085 mm are needed to ensure the production series. The total force for cutting out two components in one stroke was determined to be 4680,4 kN. Due to the given strength and dimensions of the sheet metal, a triple-action hydraulic press FB one 7000 was chosen for production. The work also includes a technical-economic evaluation, through which it was found that the given production becomes profitable at 34987 pieces. Therefore, due to the size of the production series, it can be declared that the production is profitable.
