The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.
Design of cutting device for precise cutting of aluminum alloy tubes
Schaffelhofer, Igor ; Omes, Jiří (referee) ; Tůma, Jiří (advisor)
This master thesis is focused on the design of device for precise cutting of aluminum alloy pipes, which are part of gas-insulated switchgears at Hitachi Energy. Due to the implementation of new welding technology using friction stiring, there are increased requirements for the quality and accuracy of cuts, and the overall acceleration of the cutting process, including the associated handling. The current situation is the division of aluminum pipes using a band saw, which is insufficient not only in terms of output quality but also capacity. The proposed solution in this master thesis is in accordance with the necessary quality and capacity input requirements, which is required by friction stir welding technology (FSW). In the introductory research part, the work is focused on methods of material cutting. In the next part, the requirements for the cutting device are evaluated together with the evaluation and selection of a suitable method for the design. In the structural part of the master thesis, the individual concepts of partial parts are given, where the selected variants are supplemented by appropriate calculations.
Porovnání kvality řezanky u samojízdných sklízecích řezaček
HEŘMÁNEK, Aleš
This final thesis is dealing with feed production technologies interms of different species of plants for the purpose of livestock production or energetics. The thesis analyzes one particular technology because of wide range of options on the market nowadays. The resource review chapter provides comprehensive information about history of forage harvesters and their use in crop production up to now. A significant part of that chapter describes an overview of latest technology. The thesis focuses on self-propelled machines and is complemented by a description of individual technical solutions. The metodology part contains measurement procedure and comparison criteria of particular John Deere 8300 and New Holland FR 500 machines. All the measured values had been gathered between 2019 and 2020. These values have provided the main source for acquiring further subject. The points of comparison were feed quality, grain crushing, efficiency and fuel consumption. The last criteria in that comparison are operational costs of particular forage harvesters.
