Design of single-purpose cutting machine for shortening of plant stems
Žižka, Jakub ; Brandejs, Jan (referee) ; Vespalec, Arnošt (advisor)
This bachelor thesis deals with the design of a single-purpose machine for cutting plant stems. The task of the machine is to cut already partially shortened and stripped wheat straw stalks to the required length. The operation of the machine is fully automated, the operator only ensures the supply of semi-finished products to the machine, removes the finished stalks and controls the operation of the machine. In the thesis is a search describing the existing technologies used for cutting plant stalks, the possibility of driving a single-purpose machine and possible solutions for transporting stalks. The research also includes an analysis of the necessary mechanical and physical properties of wheat stalks. Subsequently, the analysis of information from the research part of the thesis and the definition of important parameters for the design construction balance sheet is performed. In the practical part of the work are developed concepts of possible solutions of individual structural nodes and justification of the choice of individual solutions. The second part of the practical part deals with the construction design of a selected conceptual design, including calculations. The work shows a possible solution for the construction of a machine for processing semi-finished products with a large variety of shapes.

Single-purpose machine for mounting of thermostat
Hajda, Jan ; Nohál, Libor (referee) ; Brandejs, Jan (advisor)
The aim of the bachelor's thesis is to design a single-purpose machine for completion the thermostat into combustion engine of a vehicle. First of all, it is necessary to design a conceptual solution that is able to lay down the thermostat in the shortest possible time, will not conflict with construction restrictions, the installation dimensions, and last but not least, the machine will be ergonomic and user-friendly. The subsequently selected variant will be designed and based on the drawing documentation will be produced a single-purpose machine, which will operate in three-shift work.

Design of a forming machine for production of a stainless steel cup with follow die
Staněk, Michal ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
My dissertation describes the procedure and results of designing a single-purpose machine, which is designed for forming a stainless metal product from an initial semi-finished product. This semi-finished product is a 0.28mm-thick stainless-steel plate. The introduction of my dissertation outlines the evolution of the pulling technology in the Czech Republic and abroad and describes its further details. This research part also includes an overview of individual machines according to the CSN. The practical part is then further dedicated to the exploration of individual issues and requirements for designing the machine itself as well as designing the machine according to the requirements of the final pulled product.
