The production of the console deburring machines
Hlavinka, Martin ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis submitted deals with the project of the change of the production of the semi-finished product of the console which is produced by casting from the cast iron ČSN 42 2420. The component forms the frame of the deburring machine with two electric motors with the gearbox. For the suggested production the method MAG of technology welding was chosen. Because of the given technology the new construction of the component was chosen. The welded product consists of eight parts burnt from heavy-walled sheet metals. The suggested material of the construction is steel S235JR and for welding the filler rod Weld G3Si1, diameter 1 mm is chosen. For the determination of the optimal parameters of welding the testing through the slap next to the skin weld (size a5) was made. Simultaneously with the testing the fracture areas and the weld root were examined. The suggested parameters of welding were used during the preparation of WPS. For the assembling of the component the operating schedule of welding is planned.

Comparison of laser welds with using direct and scanner welding head
Kudr, Martin ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
The master thesis presents a comparison of direct laser and scanner welding. At first, using literary studies explained the technology of laser welding, followed by a practical comparison of these methods. The experiments were performed on austenitic stainless steel X5CrNi18-10 and S235JR structural steels. These methods were compared in welding times, geometry and weld hardness, mechanical properties and economy of use in industry. The comparison shows that the scanner welding is qualitatively equivalent to the conventional laser welding and is also economical.

Production Design of a Holder for Paddle Valve and Pressure Gauge
Bílek, Jan ; Harant, Martin (referee) ; Řiháček, Jan (advisor)
The bachelor thesis is focused on the design of a suitable manufacturing technology for a sheet metal holder for valve and pressure gauge control for buses. A 1.5 mm thick sheet metal roll was chosen as a semi-finished product. S235JR structural steel was selected as the optimum material. The production series was set at 150,000 pieces per year. After evaluating suitable production methods, the technology of sequential shearing and bending combined in a combined tool was chosen. In the proposed tool, the part will be produced in four steps from 11 rolls with 95.85 % utilization. The production will be carried out in a Mecânica Exacta eccentric press, model CC100, supplemented by a coil unwinding device.
