Manufacturing of wall clamp
Maleček, Michal ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
A wall clamp is used for attachment of terrace board to supporting structure. The discussed part is manufactured from sheet metal 11 375.20 which is 2 mm thick. The production series will be 150,000 pieces per year. A combination of shearing and bending in the combined tool was selected from a variant solution as the most suitable technology of manufacturing. Based on technological and structural calculations, a tool was designed with lower pressure pad at the bend point. For this tool was also made fundamental drawings. In view of the total moulding force and work, LEN 40 C press with the nominal force 250 kN (manufactured by TOMA INDUSTRIES s.r.o.) was selected. Necessary manufacturing costs of one part were determined from an economic evaluation. According to a break-even point, the manufacturing becomes profitable for a series of more than 89 196 pieces.

Manufacturing of lift bracket
Měřičková, Petra ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bracket is used to attach the movable mechanism of elevator door. The component is made of constructional steel 11 375 with the thickness of 3 mm. The batch size is 30 000 pcs/year. The rolling cutting method, followed by bending in the combinated tool, was chosen as the optimal technology. Technological and constructional calculations were carried out and the tool was consequently designed. The basic drawing documentation for the tool was implemented. LE 400 press with a nominal force 4000 kN was selected from machinery equipment company. Cost of production of one piece were established, the production becomes profitable for a series of more than 19 133 units / year.

Production of anchor foot
Kovář, František ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The present bachelor thesis deals with a design of anchor foot used for fixing wooden structures to concrete foundation. The anchor foot is manufactured from 4 mm thick sheet steel 11 375 (S235 JR); the batch production is set out for 100,000 pieces per year. From among production possibilities, production on a combination tool was selected as the most optimal production technology. Based on the literature study of cutting and bending technology, an optimal production process of new anchor foot has been designed. For these production technologies, technological and control calculations have been carried out. Using these calculations, the combination tool was designed and project documentation was worked up. With regard to the size of total forming force, the eccentric press LKDR 500 from ŽĎAS Company was selected. In economic terms, the production costs were calculated for one anchor foot and the turning point of 8,232 pieces was found; exceeding this point makes the production profitable.

Manufacturing of wall clamp
Šobáň, Pavel ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The wall clamp is used for attaching columns or pillars to a concrete foundation. It is made from structural steel 11 375 in the form of sheets with a thickness of 4 mm in the production run of 150 000 pcs/year. A combination of shearing and bending technologies in a progressive forming tool was selected from various options as the most appropriate. On the basis of structural and technological calculations, an instrument was designed, for which the technical documentation was elaborated. Due to the total forming force and work, the forming machine LDO 800 A/S from Šmeral Brno a.s. was selected as the manufacturing machine. The production cost per one part 53.66 CZK was determined using economic evaluation; based on the break even point, the production becomes profitable for the production run with the minimum number of 13 065 pcs.
