Manufacturing of the box
Bednář, Jaroslav ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
This thesis concerns the design and production of a rotary-shaped soap box made of chrome-nickel austenitic steel 1.4301 0.5 mm thick, with a production batch of 50,000 boxes per year. Due to the size of the batch, the cutting and drawing technology without wall thinning was chosen for one drawing operation using a single tool. Based on analysis of the possibility of producing the tool and the necessary calculations, a tool was designed for the production of the lid and another tool was designed for the production of the lower part of the box. The corresponding hydraulic presses were then selected. A CUPS 25 DEU press from HŠV Polička with a forming force of 250 kN was selected to produce the lid and a Formetal PPCT-200 press with a forming force of 2000 kN was selected to produce the bottom part of the box. The production process is fully automated with an unwinding, straightening and scrapping line from Šmeral.

Production of a rotating vessel
Novák, Václav ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis is concerned with the concept of an rotating vessel, that is a part of cotton candy machine. A drawing is cylindrical shape with circular a hole in the bottom, which is made of austenitic chrome-nickel steel 1.4301 with the thickness 1,5 mm. Due to the production volume 50 000 units per year, the pulling technology without wall thinning was choosen. The process of drawing will be performer in one operation. Due to calculated force, the ZHS 400 hydraulic press with a nominal force of 4 000 kN was chosen.
