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.

Forming limits for the bending process of tubular components
Maleček, Michal ; Peterková, Eva (referee) ; Samek, Radko (advisor)
Currently, rotary draw bending is frequently used method in industry. Nevertheless, it has been limited for long time by different types of defects. Submitted thesis deals with the study of the influence the bending radius and wall thickness on the quality of bent. Practical part of the thesis includes experimental rotary draw bending of tubes. The work also solves determining actual values of the wall thickness; ovality, bent shapes, the section modulus in bending and the neutral axis of the tube On the basis of evaluation of criteria are then set the parameters of permissible bend
