Production of air filter cover
 Procházka, Vojtěch ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The thesis is concerned with the concept of an air filter cover production .The component has a cylindrical shape with a circular protrusion and a hole in the bottom. It is made of a steel sheet 11 320 with the thickness 1 mm. Considering the production volume of 20,000 units per year, it was chosen as the most suitable pulling technology with a conventional tool without wall thinning. The component needs to be pulled in two operations, each time a retainer has to be used. The tool for each operation is separate. Technical drawing documentation is processed for the second tool. Due to the calculated force, the ŽĎAS CTH 250 hydraulic press with a nominal force of 2,500 kN was chosen. The economic evaluation shows that the production material cost for one piece is about 42 CZK. The cost of the second stroke tool is 260,000 CZK.
