Production of towing hook
Frýdl, Pavel ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
Requirements for the creation of a new technological process of manufacturing of towing hooks were cost savings by optimizing the initial blank and by creating semi automatic workplace. Selecting longitudinal rolling technology for manufacturing preform piece occurs to shorten production times and substantial material savings. By rolling of blank are secured always the exact dimensions of the preform piece and through a chain conveyors is facilitated handling with material for workers and reduced production time of forging line. By introduction of the proposed manufacturing method of towing hooks depending on the size of the series 30000 hooks per year will be achieved annually savings of over 4.000.000 CZK. Return of investments for the acquisition and adjustment of forging rolls and conveyors is 2,2 years.

System for evaluation of upsetting test
Janečka, Dominik ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The thesis deals with the proposal of measurement system for evaluating upsetting test. The variables for evaluating the test are obtained by using sensors of measuring devices. The necessary magnitudes are force, track and temperature. For this purpose they were used sensors HBM R6C, HBM W50 and thermocouple type K. The sensor signals are amplified by measuring modules Dewetron and transferred to a PC by measuring card NI USB-6009. There are further processed by evaluation program DEWESoft 6.5. In a final part are performed a verification measurements to assess system function.

Evaluation of upsetting test
Vávra, Roman ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
This work is focused on theoretical and practical processing upsetting test. There is an explanation of their significance in engineering. Also, there are described various kinds of tests and their evaluation. Furthermore, the work deals with the experiment for a specified material MS 68. This material was compacted using two test machines equipped with measuring software. First machine is a hydraulic press CZR 600 with software DEWESoft and the second is a universal testing machine ZD 40 using software M-Test. An evaluation based on the collected data is included in the form of deformation resistance curves of tested material.

Forging of the "lock-bolt"
Frýdl, Pavel ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
To lock-bolt manufacturing was selected technology of die forging. Lock-bolt is made of 11375 steel in a series of 2700 pieces per year. With the use of literary studies and practical knowledge has been developed technological process fittings. It includes the draft instrument stainless steel 19663 including drawings. Forging is performed on a hydraulic-pneumatic hammer KJH 2 with a nominal value of 20 kJ impact work. Blanks are cut from bars 30 mm 6 m long to bars 52.2 mm long. The techno-economic evaluation shows that the price of a forging is 4,71 CZK and for production will be need 24 pieces of bars.
