Manufacturing of a jet half coupling
Ostřížek, Jan ; Štroner, Marek (referee) ; Řiháček, Jan (advisor)
The work deals with the design of the production of a jet half coupling made of aluminum alloy AlMg1Si1Mn. At the beginning of the work is an analysis of possible production methods, of which the most suitable method of die forging. Based on the evaluation of technological technology, shape adjustments are made, additions and dimensional deviations are selected. A semi-finished product 50 x 108 mm is determined from the forging volume. The crank press LZK 1600 P / SH is chosen for forging. According to the standards, 2 forging and 1 finishing dies are designed for the forging. At the end of the work is also given an analysis of cutting, on the basis of which the press LKOA 200 is chosen.

Design of robotized workplace for die forging
Krejčí, Radek ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of technology for production of wheels to be manufactured by die forging 15 142 low-alloy steel at an amount of 500,000 items per year. Based on a consideration of the suitable methods of manufacture, die forging on a Jing Duann FP-1600G vertical forging press was chosen as the best, as documented by the necessary technological and design drawings. A die with inserts made of 19 552 steel was designed for this machine. In view of the volume of annual production, a fully automated workplace was designed consisting of three robots and a chain and pan conveyor. In the conclusion there was a technical-economic evaluation of costs for the material of the semi-finished products and price of dies for annual production.

Manufacturing of mudguard holder using forging technology
Ondráček, Miroslav ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

Shaft manufacturing using forging technology
Vaško, Michal ; Kopřiva, Miloslav (referee) ; Šlais, Miroslav (advisor)
This diploma thesis deals with project of shaft manufacturing using drop forging technology. This technology is manufacturing using cubic forming on vertical forging press. Work includes detail data for working out technical drawings of suggested component. Thanks to modification of parameters and forging a whole we reduce material waste which is compared to turning technology. Production process is adapted to established production process in company Kovarna ZETOR Brno. Further the work includes cost price of one forging from the set of 30 000 products a year. The work also contains background research of drop forging technology, technical drawings, production process list and simulation outcome for drop forging of the suggested komponent by software FormFEM.

Hydraulic press of current production
Kolbábek, Lukáš ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
In this thesis the background research is performed and a description of the basic parameters and parts of hydraulic press of current production. The advantages and disadvantages of hydraulic press are compared over the mechanical press. It deals in detail with constructional and technological division of press. The individual uses are described for the technology of sheet metal forming and solid forming metal materials where specific manufacturer and type of press are indicated. It further describes the new trends in use of press for production of car body parts in the automotive industry. In conclusion the basic formula for the design of the press are outlined.
