Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.

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.
