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.

Analysis of appropriate finishing technology after deep drawing
Šobáň, Pavel ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
This bachelor thesis summarizes information about appropriate finishing technology after deep drawing. The thesis is focused only on the most used and most proper methods, which include material parting operations, such as plate shearing, laser, plasma, water jet and saw cutting, and machining operations, such as lathe-turning and grinding. For each of the mentioned methods, a principle of the selected technology is described and also its suitability for the present problems. The thesis compares the individual methods considering their advantages and disadvantages for removal of uneven edges of cylindrical shells.
