Manufacturing of nibbling parts
Moravčík, Juraj ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work describes principles and methods of punching starting from gradual sheering. In this work they were included advantages and disadvantages dividing punching tools of the two design, it´s revolver and cassette. There were also described of forming tools and some of their basic representatives, which are in practice often used. The two basic principles of machines have been described on the example of companies Prima Power and Trumpf.

Manufacturing of castor holder
Moravčík, Juraj ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
The thesis solves the design of the technology of manufacturing the furniture wheel holder from a sheet thickness of 11 321 with a thickness of 2 mm. On the basis of the variant cutting and bending solution, a production solution was chosen in a process proggressive die. As a blank, a sheet metal strip is selected from a 64.1 mm roll. After the technology evaluation, the distances of the openings from the edge of the part and the bend were adjusted and the technological calculations determined the necessary total forces, work and other parameters. On the basis of the previous calculations, the S 160 E eccentric press of Šmeral was chosen as the most suitable machine. The designed tool works in six steps and includes nine cutting and one bending section together with two viewers and one spring retainer. Economic recovery has shown profitable production of the given series where the total profit is CZK 999 310,61 and the reversal point occurs after production 58 382 pieces.
