Construction of rolling machine of steel sections
Křivohlávek, Pavel ; Pavlík, Jan (referee) ; Matějka, Petr (advisor)
The aim of this thesis is to design steel beams bending machine. In the introduction, is characterized by a bending machine and carried out research costs, including factory-produced manufacturers. Followed by a proposal of alternative solutions, evaluating them and selecting the most appropriate conception. The next section is described in detail the proposed model, including stress analysis of loaded parts. The thesis also examined the safety of a forming machine, prepared an analysis of possible defects and their consequences in the design. Finally, it created the design documentation on the proposed machine made pricing and maintenance described rolling machine.

The manufacturing of component from wire
Pecinová, Hana Elisabetha ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
Project elaborate within bachelor's degree, present design production of components called "fan". Component is made from rod diameter 4 mm, of material ČSN 41 1343. Based on the literature study of issues bending and roll bending were performed some of calulations and for others was developed sugestion. Further was designed hand-operated machine for forming- bending and roll bending. For this hand-operated machine was drawn tracing documentation of completation and selected parts. Machine is primaly designed for solved component, but it can be used universally for stock part of small dimensions. In the end was carried out economic balance for production of machine and component.

Strip rolling
Kornherr, Milan ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
This bachelor thesis focuses on theoretical analysis of the role of plastic deformation in the process of rolling strips. The work explains progress of stress waveform during straining and lightening. This work also focuses on computing of spring loading and bending moment due to specific curvature of strips. Report at the end of this work includes an illustrative example with executional program.

Modern methods of roll bending
Fišar, Luboš ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The project elaborated within the frame of bachelor study B2339-00 Mechanical engineering deals with creation of review of modern methods of roll bending. Pursuant to of the literary pursuit a problem of the sheet metal forming and internet research is in the work directress dilemma of roll bending, machines and tools for sheet roll bending and section roll bending, special roll bending machines and equipment. Examples of producing components are last part of project.

Technology for bending unsymetric profile of steel
Walach, Lukáš ; Matušková, Jarmila (referee) ; Dvořák, Milan (advisor)
The present thesis deals with the determination of procedural parameters of given bending profile including the calculation of spring-back, especially the bending force. It compares the differences and the benefits of two different technologies of producing a blank, the simple bending and the technology of rolling. The technological process suggested involves technical-economical evaluation, supplemented with the drawing documentation.

Manufacturing of tubes by forming
Szczygiel, Pavel ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the basic methods of manufacture of tubes, especially focuses on the technology of seamless tubes. Assess the appropriateness and inappropriateness of individual production methods used and presents technology and types of lines used in practice. It describes in detail process of production seam pipes with a diameter of 116 mm and a length of 97 m in the plant ArcelorMittal Tubular Products Karviná a.s. Also describes in detail each operation in the working section of the strip preparation, welding and is reduced.

Roll bending technology
Hejna, Jaroslav ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The paper deals with the research of sheet metal bending technology. This technology is suitable for producing both cylindrical and conical parts. First summarized technological and physical nature of the technology. Also important is the method of making cones using bending machines. Different types of machines are disassembled. From the smallest hand to the largest three-roll maschine. In the future, the two-cylinder machines are the most promising. They are especially suited to their variability and also because the component can be manufactured faster than any other machine.

Design and construction of a rolling machine
Salajka, Josef ; Osička, Karel (referee) ; Dvořák, Jaromír (advisor)
The aim of this bachelor thesis was to design and construct a machine for bending profiles, which will be then used in home workshop. The work itself discusses the issue of profile forming in mechnichal engineering. Specifically a description of bending, its division and machines comonly used. Furthermore acquaitance with rollinch machines on the market and their manufacturers. According to existing solution found in the catalogs, a custom concept was designed, for which a 3D model and mechanical drawing were made. A prototype of concept was made. The work describes the functionality of the designed machine alongside its demonstration. In the end, the whole bachelor thesis was evaluated from technical and economic point of view.
