Production of the cover
Dymák, Petr ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The cover is a component used to cover the motor bearing. A material, used for its production, is steel 11 320. Of the possible technologies was selected as the most suitable for production the method of conventional campaign without wall thinning. For production of the cover has been calculated the blank diameter of 477 mm, which is made of a metal sheet with the dimensions 1 x 3000 x 1500 mm. Literary study is focused on the analysis of the technology. Semi-finished product of cover component will be cut in sheet measuring 1 x 1500 x 3000 mm. For forming of the component will be used hydraulic double-acting press CTH 250 from company ŽĎAS a.s. After the economic evaluation was determined price of one part to amount of 62 CZK in series of 100 000 pieces/year.

Solution turning technology of part "víko" with coated cutting tools
Prokop, Karel ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
In this bachelor´s thesis is processed analysis of part called cover and there is also processed proposal of the technology its manufacturing. Into proposal of manufacturing are included conventional tools which are compared with different type of manufacturing by tool called EcoCut. For both varieties is elaborated technological process, instruction for turning with counted mechanical times and consumption of changeable cutting tips.

The Production Technology the fan cover
Hudousek, Jiří ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
HUDOUSEK Jiří: The Production Technology the fan cover. The project elaborated in frame of bachelor studies is submitting design of the fan cover production with sheet metal forming technology. Based on the literary pursuit a production process of the workpiece was designed when the blank is formed with deep drawing technology without thickness reduction (pure drawing) and subsequently completed by trimming to size, dimpling of the shell bottom, assembly holes punching and surface treated. Based on the calculation drawing in die with blankholder was designed for drawing operation and according to the force needed and tool size a hydraulic press ZH 160 (manufacturer PRESSHYDRAULIKA, s.r.o.) was selected. Material chosen for the production of workpiece is deep drawing steel sheet DC04 (ČSN EN 10130), production batch is 100 000 pcs. per year.

Mechanical design of locking device of swimming-pool roofing
Machýček, David ; Čudek, Vladimír (referee) ; Paloušek, David (advisor)
This bachelor thesis deals in its background research part with the possibilities of covering or roofing the level of water of a swimming pool. After stating the options for roofing the swimming pool, the efficiency of this roofing is analysed and main advantages of the roofing are found. The constructional items of the swimming pool roofing are also described in the research. At the same time, the most widespread system of the blocking of the swimming pool is analysed and explained. In a part of the thesis, which deals with new solution for covering the swimming pool, individual solutions are proposed first. There are two solutions in this proposal. The first one comes from the idea of a trackage guidance of all the segments, which basically is one of the most widely used systems on today’s market. The second proposal is proposed for a partly trackage guidance of the segments. A suggestion of the partly trackage guidance was chosen for the constructional solutions, for which a 3D digital model has been created and from this model sketches of sets in open and closed state have been generated and adjusted.

Localization of reinforcement in elements of reinforced concrete structure
Fusek, Aleš ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This bachelor thesis deals with the search for non-destructive methods of reinforcement in concrete structures using electromagnetic indicators. The theoretical part describes the methods of diagnosis reinforcement capabilities and limitations of the methods of electromagnetic indicators and comparisons with other methods. Furthermore, a overview of the reinforcement used in the 60s of the last century. The practical part describes the measurement on reinforced concrete construction hall and compares it with the measurement obtained on the models in the laboratory at the focus of the sensitivity of measurements and data processing.

Production of air filter cover
Procházka, Vojtěch ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The thesis is concerned with the concept of an air filter cover production .The component has a cylindrical shape with a circular protrusion and a hole in the bottom. It is made of a steel sheet 11 320 with the thickness 1 mm. Considering the production volume of 20,000 units per year, it was chosen as the most suitable pulling technology with a conventional tool without wall thinning. The component needs to be pulled in two operations, each time a retainer has to be used. The tool for each operation is separate. Technical drawing documentation is processed for the second tool. Due to the calculated force, the ŽĎAS CTH 250 hydraulic press with a nominal force of 2,500 kN was chosen. The economic evaluation shows that the production material cost for one piece is about 42 CZK. The cost of the second stroke tool is 260,000 CZK.

Production of the "Cover" component
Král, Lukáš ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The thesis proposes the production design of a cover component used as a ventilator cover of a water pump. In compliance with the studied literature, the cover will be made from polypropylene using the injection moulding technology. Based on the technological calculations, it puts forward a complete double mould with a cold inlet. The design solution was verified by simulations of filling and cooling, and a suitable injection machine was selected as per the calculated parameters. Finally the thesis explores the possibility for defects and presents the technical-economic evaluation for the entire production.
