Production of holder
Andris, Tomáš ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated the design of technology production of the holder used for fixing pneumatical cylinder at the testing rack. The holder is manufactured from 2 mm thick sheet metal made of structural steel 1.0038 in a production series of 6,000 units/year. After considering the individual production options, shearing in transfer die and simple bending die were selected. Based on the literature study of shearing and bending technology, an optimal production process of the holder was proposed. After technological, structural and verification calculations, the tools were designed, and the technical documentation was prepared. For the production of the holder was selected eccentric press LEXN 100 C made by Šmeral Brno a.s. This press meets the requirements of the forming force, forming work and the dimensions of the tool. According to the calculated economy of production, the production costs of one holder were determined with a 30 % profit to 97 Kč. The turning point when production becomes profitable was calculated to 4 454 units.

Manufacture of car lock components
Andris, Tomáš ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on the proposal of manufacturing technology of the opening lever for a car latch. The lever is made of S355MC sheet metal with thickness 2 mm, production series is set for 400 000 pieces per year, which includes 200 000 pieces of right and 200 000 pieces of left version. After considering several production methods, combined progressive die was chosen. The part is made in ten steps, which include shearing and bending. Necessary technological, design and safety calculations were also made. For production was chosen eccentric press S160 made by ŠMERAL company. Surface protection of the part will be provided by galvanizing. At the end of the thesis a technical and economical evaluation is provided. The final price of one piece of lever is calculated to 13,3 Kč, economical turning point when production become profitable was calculated to 156 339 pieces.
