Production of cooling cabinet
Halabrín, Marek ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The thesis deals with presenting an assembly proposal of a cooling cabinet. The cooling cabinet is made from an austenitic steel plate of the ČSN 17 240 grade with a thickness of 1.5 millimetres. The assembly proposal is composed according to the design documentation. The number of the assembled pieces is 200. The manufacturing shall be made with the use of bending and punching. These manufacturing techniques form a part of this thesis. Finn power C5 with a nominal force of 300 kN and Trubend 5170 with a nominal force of 1700kN are the machines chosen for the manufacturing process. These are standardized machines made from a quenched steel and a steel of the 42CrMo4 type. A technological-economic evaluation comparing expenses of the manufacturing also forms a part of the thesis as well.

Design for production of lower part of charging station
Skalník, Petr ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
This master’s thesis deals with a proposal of production technology of bottom part of charging station which is manufactured by DEL a.s. The component will be made of austenitic steel 17 349 which is 2 mm thick and its production series is 100 pieces a year. Punching and bending by MAG and TIG methods were chosen as the most suitable methods from the considered manufactoring technologies. Stud bolts will be welded by capacitor discharge. Based on the analysis of the technological calculations and the available machines in the manufacturing company was chosen that production is going to run through a punching press Pullmax 720, hydraulic CNC bending press OptiFlex 130 t 3,1 and welding sources TransPuls Synergic 3200, TransTig 1750 Puls and Nomark 65+. Technical and economical evaluation established cost calculation of semi-finished product material, welding wire, gaseous shield and stud bolts. The price of one piece is 3 117,70 Czech crowns.

Selection of appropriate technology for the production of welded constructions of boiler JE 12 and JE 6
Janás, Milan ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The diploma thesis on the selection of appropriate technology to produce the welded construction of electric boiler JE6 / 12 aims to evaluate available production technologies and choose the most suitable of them. Choosing the technologies focuses primarily on those that are available at Slokov. Due to the connection of the welding robot to the production, it is necessary to consider the overall connection of the production and the high accuracy of the production. The individual methods of production, material separation, welding, bending and surface treatment are first theoretically analyzed and their advantages, disadvantages and parameters are summarized. Subsequently, it is practically tested individual technologies for a representative part and it evaluates the achieved parameters and economics of production. With the results obtained, the most suitable technologies are selected. With the selection of technologies, there is a need for a change in design and production parameters. Changes and modifications to the design describe another point. To achieve maximum efficiency and quality of production, a welding robot is used to make welds. The description of the production, modifications and overall design of the robot describes the next point of this work. The last part summarizes the economics of selected production technologies and details the technological process. The aim of the thesis is to design such technologies that will be advantageous from the point of view of the economy and from the perspective of the available possibilities of the company.

Production of Cover of Regulator Tank
Kudláč, Lukáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
This master’s thesis deals with suggestion of production of sheet metal cover in Limid Mohelno s.r.o. Piece serves as cover of regulation device of rail vehicles with visual function and it’s manufactured from corrosion-resistant steel ČSN 17 240 with thickness 1 mm. Esthetical impression is ensured by grinded surface K240. The master’s thesis includes literary studies and problems of chosen technologies, technological calculations and choice of machines including tools. As the best manufacturing technology was chosen punching on TruPunch 1000 and bending on press brake SafanDarley E-Brake E-100. Technical and economical evaluation was made based on selected technology and compared with another manufacturing options.

Production covering grids of welding machine
Rous, Miroslav ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
This thesis has been written in the time of my bachelor studies and it describes a production design of a rear cover of a welding set. It focuses on manufacturing of ventilating holes in this component. The cover is made of steel of standard quality 11 320, 1 mm thick. The flattened out shape of the component will be stamped on a Finn Power SG6 machine and subsequently it will be bent on a press brake Safan DNCS 225-4300. The practical part of this thesis contains a design of an instrument making the ventilating holes and an economic assessment.
