Manufacturing of chain wheel for BMX bike
Figar, Erik ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of suitable technology for the production of BMX sprocket made of sheet metal 14 220.3, with a thickness of 4 mm. The production series is 200,000 units per year. Following the analysis of different production options, fine-blanking technology has been chosen as the most suitable precision cutting technology. A technological proposal has been created, which includes the choice of a suitable appropriate blank (sheet metal 4x2000x6000 mm) as well as the design of a shearing tool with the corresponding drawing documentation of its selected parts. On the basis of the calculated values, HFA 4500 plus hydraulic triple action press manufactured by the Feintool company was selected as a production machine. In the last stage, technical and economic assessment of the efficiency of this production was performed.

Production of universal opener by fineblanking technology
Kučera, Radek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The aim of the thesis is to design a manufacturing technology of a part of the universal opener with an innovated design. The component is made of stainless steel 17 240 (X5CrNi18-10). The blank is 2 mm thick sheet metal. Within the literary study the comparison of the possible technologies of manufacturing has been carried out. With respect to the batch size (200 000 pieces) and to the required quality of the component the fineblanking technology has been selected. For the manufacturing of the component a triple action hydraulic press HFA 3200plus has been chosen. This press will be coupled in production line with a feeding line FBA 8/300. The main point of the thesis is to design a cutting tool and to create a drawing documentation. Another part of the project is the technical and economical evaluation of the designed manufacturing process.

The Production Technology of unrotary part with flange
Andres, Tomáš ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
Bachelor´s thesis describes design of the production of unrotary part with flange made by drawing technology. Produced component is a single cylinder head cover four stroke engine, which is equipped with holes for attachment to the cylinder head and the spark plug hole. The prodiction series is 500 000 pcs per year.The material used for production is deep draving steel DC 04 (ČSN 11305). For the production was designed drawing tool and by the calculating required drawing forces was selected power presss VIVEK MACHINE TOOLS type VPPP - 10 with force 2000 kN. At the conclusion was evaluated technical and economic evaluation of production by seting a tipping point.
