The manufacturing of oil filter cover
Foltýn, Michal ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The diploma thesis was elaborated in the frame of engineering studies branch M-STG. This project is submitting design of technology production of oil filter cover from the deep drawing sheet iron 11 305.21. The size of production lot is 300 000 pcs/year. In relation to the shape of drawn part and the size of production was chosen the deep drawing technology and designed manufacturing process. For production was on the basis of realized engineering calculations chosen hydraulic deep drawing press and constructed drawing die. The drawing die is on the basis of a transfer conception and includes two blank holders and two ejectors.

Production of gear
Havlíček, Roman ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of production technology of the chain wheel used in the scraper conveyor made of 14 220 steel. After considering all production options, die forging was selected. On the basis of chosen technology, shape adjustments, additions and dimensional tolerances were made. From the volume of the forged wheel, a semi-finished product with a diameter of 150 mm and a length of 106 mm was determined. Based on the scale of series, the machinery equipment of the company and the size of the forged piece, the KHZ 16A hammer, with a nominal energy of 160 kJ, was chosen as a forming machine. According to the standards, a single-die dies were designed for the forging. The LKOA 200 press was chosen to cut off the flash and the membranes. Additional machines for manufacturing were chosen and technological standard was compiled. At the end costs of the material for production amounting to 2 566 045,3 CZK and the cost of production of die in the amount of 187 000 CZK were calculated.

Analysis of appropriate finishing technology after deep drawing
Šobáň, Pavel ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
This bachelor thesis summarizes information about appropriate finishing technology after deep drawing. The thesis is focused only on the most used and most proper methods, which include material parting operations, such as plate shearing, laser, plasma, water jet and saw cutting, and machining operations, such as lathe-turning and grinding. For each of the mentioned methods, a principle of the selected technology is described and also its suitability for the present problems. The thesis compares the individual methods considering their advantages and disadvantages for removal of uneven edges of cylindrical shells.

Production of a part of the data projector bracket
Starý, Petr ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The diploma thesis presents technology production design of a data projector bracket made of 2 mm thickness 11 321 steel plate. Considering the large production quantity and maximum tolerable deviations, a progressive die tool along with cutting and bending was chosen as the optimal solution for this type of production, based on a variant solution. Technological aspects were assessed, the production process was established, and technological and control calculations were performed. According to the total forming force of 2 000 kN, the LDC 250 mechanical press with a nominal force of 2 500 kN, manufactured in Šmeral Brno a.s., was chosen to meet the production requirements. The chosen material in a form of metal sheet coils will be supplied to the machine by a feeding device. The article will be manufactured in six steps. Based on technical-economic evaluation, the final price of a single piece in a series of 250 000 pieces per year was set at 30,80 Kč.

Manufacturing of semifinished products
Janáček, Adam ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
This thesis deals with manufacturing of semi-finished products specifically with methods of metal forming and welding and describes their principles and limits. Almost every types of semi-finished products are manufactured by rolling. Drawing is method for manufacturing rods, wires and tubes. Rods and tubes are produced by extruding. Welding is used as manufacturing method for tubes with seam.

Manufacturing of body latch
Braško, Zdenko ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
Bachelor thesis is concerned with the design of production a body latch. Latch is used for engaging the door in a closed position. Component is made of structural steel 11 321 with a thickness 1 mm. The batch size is 35,000 pcs/ year. As the optimal production technology was chosen method of rolling cutting with shallow drawing in the combinated tool. Technological and constructional calculations were maked and tool was designed by it. For this tool has been created drawings. Of the total work force requirements and for the production of components was set press machine LEN 40 C. The cost of production of one piece were determined to 10,57 CZK / pc. Production becomes profitable for a series of more than 25 083 pcs / year.
