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.

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.

Manufacturing of the Motorcycle Rosette
Radnický, František ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This bachelor thesis is focused on design of suitable technology of motorcycle sprocket, made from sheet metal 11 500 with a thickness of 6 mm. The production series of this component is 100 000 pieces per year. Before selecting the most suitable technology for the production of rosette the evaluation of different available technologies was carried out, of which as the most appropriate method, the accurate cutting with pressing edge is selected. The technological and constructional solution is elaborated, which involves selecting of the appropriate blank (sheet metal 6 x 2000 x 4000), design of cuttingg tool with its documentation and the choice of production machine triple-action hydraulic press Feintool HFA 11000 plus. In the final phase, a technical and economic evaluation of the efficiency of the production is performed.

Manufacturing of cylinder holder by fineblanking technology
Piterka, Miloslav ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis is focused on production of a cylinder holder, which has been made from stainless steel 17 240. The product is 6 mm thick and there are 200 000 pieces produced per a year. After analysis of manufacturing technology there has been selected fine-blanking technology with v-ring for production of these components. For this reason there has been developed a study. Then there have been evaluated the technological and control parameters of the components. There has been selected the single row arrangement on the sheet of tin and chosen a stock of blank metal sheet for manufacturing with strict measurements (8 x 1 000 x 2 000) mm. There has been made the suggestion of design of a cutting tool. Hydraulic press Feintool HFA 8800plus has been selected for the final production. Eventually there has been evaluated the economics of production of fine-blanking with v-ring due to break even point.

Manufacturing of driving chain gear
Řiháček, Jan ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the production of driving chain gear, made from sheet metal 14 220.3, with a thickness of 8.0 mm. Set production series is 150 000 pieces per year. After the analysis of possible production methods was choosed fine-blanking technology as productive metod. It was elaborate the proposal of technological solution and constructional design involves selecting of the appropriate blank (sheet metal 8 x 1250 x 2500 mm), design of cutting tool with its documentation and the choice of production machine (triple-action hydraulic press Feintool HFA 3200 plus). In the last part of thesis was done an economical evaluation to assess the efficiency of the production.
