Design of Forming Tool and Machinery for Couting out of Pad
Kolář, Milan ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The Diploma Thesis presents a draft of designated automatic apparatus for cutting out and assembling pads for pressure control valve (DRV2). The theoretical chapter of the Thesis contains selected findings from theory and technology for material cutting. The next chapter contains design solutions for a designated apparatus for cutting and assembling pressure control valves. The pads are etched from 0,08 mm steel plates X2CrNi Mol7-12-2. The shape of the pads is etched on a 35mm-wide belt that is wound up onto a drum. The draft of this new technological facility has been elaborated in accordance with the most suitable technological variant. The cutting tool is made of steel 19 437 that is thermally processed at HRC 62-4. Estimated annual volume of production series is 2 mil. pcs. The cutting and assembly processes are executed with the aid of this designated automatic apparatus.

Comparision of FEM models of joints
Hlaváč, Martin ; Hrůza, Václav (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the comparison of alternative models of the simplified joints used in the FEM models of complex models with detailed joint details. This is essentially a screw connection with dowel bolt and standard bolt, weld connection "T" and overlap weld connection. Individual connections are compared in the simulation results of matching models.

Manufacturing of ignition cover pad
Dostál, Martin ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis solves the design of the technology of production of the ignition cover pad made of steel 11 321 with a thickness of 1 mm with zinc surface treatment. It serves as part of the motorcycle engine sealing system. The part is rotating in shape with a diameter of 35 mm and consists of a central extrusion and a hole. The size of the series is 25,000 pieces per year. Production by a progressive compound tool from a coil with dimensions of 1200 x 500 mm is chosen. 3 forming operations with eating between steps are selected, which are implemented by cutting and embossing technologies. The necessary forming work of 476 kJ and the force of 267 kN are determined, according to which the PRESSIX CNV4 eccentric press is chosen. The machine is introduced into the automated Shungdar SJD and SJK production line, which consists of a straightener, unwinder and feeder.
