A design of punching tool
Bastl, Dominik ; Omes, Jiří (referee) ; Tůma, Jiří (advisor)
This bachelor thesis deals with the design of a special punching tool for a bending machine. The aim is to design a punching tool which, thanks to its compatibility with an existing bending machine, would allow punching and bending of square tubes in one profile clamping, thus streamlining the entire production compared to the existing production process.

Development of Transport Cart with Stretcher
Bastl, Dominik ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The diploma thesis deals with the design of a transport gurney with a stretcher for people up to 150 kg. The aim is to design the simplest possible construction of bent and welded pipes and profiles with a thickness of 1.5 and 2 mm from E235+CR1 S2 steel, based on an already functional product on the market, taking into account the commissioning company's available machinery AUDY s.r.o. The theoretical part of the work is devoted to the main production technologies, i.e. bending and welding. A literature search is prepared for the mentioned technologies. Bending is more focused on length of the blank and springback angle. In welding, the weldability of the selected steel is assessed, a suitable welding wire with shielding gas is selected and the process parameters are determined. Theoretical findings are compared with practical outputs. The practical part includes design, prototype production and trial tests to verify the reliability of the new product. Necessary construction and technological calculations with basic drawing documentation are also included.
