Production of guiding disc
Slavík, Tomáš ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis is focused on the design of the production of a guide disk made of sheet metal DC01 with a thickness of 3 mm. The production series is set to 100 000 pieces per year. Due to the required accuracy and size of the series, it was chosen that the guide disk will be made by the method of fine blanking. A coil of sheet metal has been chosen as the semi-finished product due to percentile of material usage and size of the series. For production will be needed a total of 24 coils of sheet with length of 308 m and one incomplete coil with a length of 132 m. The total force was calculated as Fc = 887,3 kN. Due to this strength, dimensions of the sheet and floor area of the tool, a triple-acting hydraulic press FEINTOOL XFT 1500speed was chosen for the production of the part. The last step was to check whether the size of the series is profitable or lossful. It was calculated that production becomes profitable at 49 554 pieces. Due to the size of the series, it can be stated that the production will be profitable.

Design of a tool for production of shaped blanks
Řáda, Aleš ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
Master thesis reports questions about purchasing supplies for stamping shop. It solves task, that is cheaper buy blanks, or buy coils and cut them in free time of Raster 250 press. Thesis contains a design of cutting tools for production rectangular and trapeze shaped blanks. Tool for cutting of rectangular blanks is documented with drawings of assembly and main parts. The project was verified in techno-economic summary including repayment time calculation.

Manufacturing of ignition cover pad
Dostál, Martin ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis solves the design of the technology of production of the ignition cover pad made of steel 11 321 with a thickness of 1 mm with zinc surface treatment. It serves as part of the motorcycle engine sealing system. The part is rotating in shape with a diameter of 35 mm and consists of a central extrusion and a hole. The size of the series is 25,000 pieces per year. Production by a progressive compound tool from a coil with dimensions of 1200 x 500 mm is chosen. 3 forming operations with eating between steps are selected, which are implemented by cutting and embossing technologies. The necessary forming work of 476 kJ and the force of 267 kN are determined, according to which the PRESSIX CNV4 eccentric press is chosen. The machine is introduced into the automated Shungdar SJD and SJK production line, which consists of a straightener, unwinder and feeder.
