Manufacturing of metal yoke of electrical socket by compound tool
Svozilová, Lucie ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated design of technology production of the metal yoke of electrical socket made of steel DX51D + Z200 by compound progressive tool. Stock material for series of 200 000 pieces is a strip of coil. Manufacturing is realised in five steps consist of cutting, bending and flanging. For flanging was constructed a special mechanism for whose is necessary to use hydraulic counterholder, which is sold as a special peripheral equipment of manufacturing machine. The machine choice was adapted to this criterium. The servopress DSF-N1-800A was chosen as a manufacturing machine, which is made by AIDA company. The press can produce force of 800 kN and make work of 4000 J. Selling price of a one yoke is 24,5 Kč when the profit is one hundred percent. The break-even point comes with 58 140 made piece.

Production of gear
Svozilová, Lucie ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated design of technology production of the spur bevel gear, which is made of a steel rod from material 12 050. Pursuant to of the literary pursuit and calculation is designed as a threeoperational forging in an open die with using of ejector. Forging is realised in the vertical crank press LZK 1600 P/SH, with forming force 16 MN. Shearing and punching is performed in the shear press LKOA 200. Forging dies are produced from alloyed instrumental steel 19 556 heat-worked according to drawing documentation.

Effect of selected factors on the yield and health status of cabbage, carrot and onion
Koudela, M. ; Novotný, Čeněk ; Nedorost, L. ; Kocourek, F. ; Svozilová, L. ; Brožová, L. ; Doležalová, J. ; Kubíček, M.
The presented methodology summarizes the results of field experiments documenting that the selected factors influenced the development of important diseases, namely: 1. Alternaria blight cruciferous of head cabbage (in the years 2012-2013) (caused by Alternaria brassicicola) 2. Alternaria leaf spot of carrot (in the years 2012-2013) (caused by Alternaria dauci), and 3. Blight of onion and onion neck rot (in the years 2013-2014) (caused by Peronospora destructor and Botrytis aclada, respectively). The evaluated factors were: variety, crop density (carrot and onion, only), year and location. It is necessary to take into account the earliness of evaluated cultivars that also represents an important aspect of variety resistance to pathogens. In the annex, there are diagrams showing the course of air temperature and air humidity as well as the length of moistening period of leaves at both experimental locations in Troja and Svijansky Újezd in the individual years. Changes of these variables significantly influenced, in interaction with the other factors, the development of phytopathogenic fungi on the infected plants in the individual years.
