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.

Manufacturing of kitchen sink
Vágner, Lukáš ; Peterková, Eva (referee) ; Jopek, Miroslav (advisor)
The project deals with the design of production of the kitchen sink made of chromium-nickel austenitic steel 1.4301. Material thickness of the sink is 1 mm. The annual production series is 30,000 pieces. After considering the size of the produced series, a combination of shearing and deep drawing was chosen as the production technology. Shearing of the circular shape was combined with the execution of both draws into one production tool. For this design, the necessary calculations were performed along with verification by simulations in the PAM-STAMP program.The tool is clamped in a hydraulic press PO 400, which has all the necessary parameters. The coil blank is guided through the unwinding and straightening device Compact Line GLK3-1000. The selling price of one sink was set at CZK 1,300. Production becomes profitable after producing 7540 sinks.

Manufacturing of the water siphon by sheet metal forming
Toufar, Jan ; Lidmila, Zdeněk (referee) ; Jopek, Miroslav (advisor)
The thesis presents a design for the manufacturing of a foul air trap made of chromium-nickel austenitic stainless steel resistant to corrosion 1.4301. In regards to the rotationally symmetrical shape of the air trap, the most fitting technology for manufacturing was deep drawing without thinning of the side and for the preparation of the blank shearing. The selected method of drawing, results in the necessity to utilize a triple action press, which allows for the optimal connection of all selected technologies into one combined tool. All technological calculations were determined and examined. Based on these calculations, a tool was designed. In this tool, the component is assembled out of a coil in three operations of one stroke. The selected machine for production is the press Dieffenbacher PO 250.
