Design of sheet bender
Kazda, Tomáš ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
This bachelor’s thesis deals with the design of a sheet metal bending machine, which is intended for home workshops, or common craft operations. The first part of the thesis contains a overview of similar machines, that are currently available in the shops. In the second part of the thesis was selected the most optimal design, which arose from the three conceptual designs. Each design was rated and on the basis of a multi-criteria analysis were selected the best one. Final design were processed to the 3D model, which have a technical calculations and technical drawings too. After this were made a economic calculations of a final design, including a comparison with a selected models from the research part of this thesis.

Checking the accuracy of bending of the material in sheet metal bending machines VanMark
Fara, Michael ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
This diploma thesis deals with surface forming methods, especially accuracy and measurement of sheet metal bending on Van Mark brakes. The aim of the work was to make bends of samples in the range of 30 °, 60 °, 90 ° and 120 °. The size of the bend of the examined samples is influenced by the suspension of the sheet, which is not taken into account in the currently used type of protractor. The samples were then analyzed on two types of measuring devices - tactile and optical. After measuring, results were evaluated and plotted in the appropriate graphs. Based on the measurement results, a new type of protractor was designed, which will make the user's work easier and more efficient.

Design of segment sheet bender
Romanov, Dmitrij ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The bachelor's thesis deals with the design of a manual segment sheet metal bending machine. Part of the work is a theoretical analysis of the current state of science and technology in the field of material bending. The design solution of the segment bending machine is based on similar machines currently available on the market, which are analysed in this work. Then the possibilities of the construction of important parts of the bending machine are proposed, which are then evaluated for the selection of a suitable variant. The bending machine is designed for bending low-carbon steel sheets suitable for cold forming with dimensions up to 1550 x 2 mm.. The work contains calculations of the control parts of the machine, which are based on the selected material for bending. Afterwards a 3D model of the bending machine and drawing documentation of the assembly and its selected nodes are developed.

Methods of 3D bending
Kráčmar, Lukáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project is developed in the context of a bachelor's degree in Mechanical Engineering and deals with an overview of modern methods of 3D bending part. The paper presents the different methods of 3D bending components that are produced by these methods and machines on which these components produce.
