Manufacturing of the support arm
Melichar, Ivo ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis introduces a design for the technology of manufacturing the supporting arm used for positioning and rigidity of the front plate in relation to the metal socket in the container box. The arm is made of a 2 mm thick steel sheet and of a quality according to ČSN 411331 in a production series of 14,700 units / year of the left modification and 14,700 pieces / year of the right modification. After the assessment of individual production options, the cutting technology in a progressing tool and bending technology in a simple tool were selected. Based on a literary study on cutting and bending, an optimal process of arm manufacturing was proposed. After the design, technological and control calculations for individual technologies, the tools were designed, and the technical documentation for those tools was developed. For the cutting technology, an Andritz Kaiser press with a PV120F / 1 labelling was selected. For the second production step, bending technology, a press from Šmeral Brno a.s. with a LEN 63 labelling was selected. Both of these presses meet the requirements of both the forming force and the tool dimensions. After the economy of production was assessed, production costs of one piece were determined with a 30 % profit assumed to 28.47 CZK. The turning point when production became profitable was found after the production of 18,121 units.

Production of the gutter hook
Šobáň, Jakub ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
This bachelor thesis introduces a gutter hook technology production design made of 5 mm thick 11 321 steel sheet. Progressive die tool shearing and bending was chosen as the best production technology. Technology and structure calculations were done for this method. A three step hole punching bender tool has been designed. HMG 100 press produced by TVARtech company – stroje s.r.o. with a coil feeding line by Coiltech company was chosen for production in accordance with the power requirements.

Production of the Folding meter lock
Václavek, Petr ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The thesis proposes a concept of manufacturing the folding meter lock. The part is made from DC01+LC steel of 0,3 mm thickness. The series size is 100 000 pcs/year. A forming in a progressive combination tool combining shearing, bending and stamping was chosen for the production, based on the analysis of possible solutions. The tool, designed on the basis of literary research of used technologies, produces the part in eleven steps exerting maximal force of 38,5 kN. The production will take place on an eccentric press LEN 40 C. The market price of 3,38 Kč for one piece was established by the technical and economic evaluation.

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.

Simulator of typical rotational machinery components faults
Vaľko, Matej ; Beneš, Petr (referee) ; Čala, Martin (advisor)
The objective of this thesis is to create a library in programming environment LabVIEW by company National Instruments, which objective is to simulate vibrations of different mechanical components, such as shaft, rolling element bearings, plain gearing and planetary gearbox in different circumstances and failures. The theoretical part contains information about typical failures of this mechanical components and their typical failure frequencies obtained from literature. In the description of theoretical part is inscripted simulator with user interface in already mentioned programming environment LabVIEW. Result of this thesis is library, which images time course of vibrations and spectral analysis for diffrent components with their respective failures.

Manufacturing of the Wall Bracket
Fridrich, Ladislav ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis deals with a suitable design of production technology for a wall bracket, which will serve as a speaker positioning system. The part is made of non-alloy structural steel S 235JR with a thickness of 3 mm. The production series is set at 200,000 pieces per year. After evaluating the production possibilities, the technology of bending and progressive cutting is chosen, which are combined in a combined tool. Subsequently, the most suitable arrangement of the part on the sheet metal strip is selected and the sheet metal coil is selected as a semi-finished product for production. Furthermore, technological calculations are performed and drawing documentation of the tool is made. Based on the calculated values, the production machine Mecanica Exacta model CC250 from the company Formetal s.r.o.

This master’s thesis presents a proposal for the technology of manufacturing sheet metal part, which is a part of a bicycle wall bracket. The component is made of steel sheet ČSN 11 325 with subsequent surface treatment by galvanizing. Due to the chosen method of manufacturing with a progressive stamping die, the research part is focused on the technology of shearing and bending. Technological calculations were performed for the most suitable production variant, on the basis of which a mechanical press ANDRITZ Metals with the designation KSTU 2000-20-4G-PSE was chosen. Furthermore, the design of the tool itself is presented, which is substantiated by drawing documentation. At the end of the work, a technical and economic evaluation of the produced series of 300 000 workpieces per year is calculated.
