Production of holder by solid forming
Šimon, Miroslav ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The aim of this dissertation is to design an optimal technological processing of a given component by solid forming. This work includes a bibliographic study, which is the source of information for the solutions. Another important topic is the global technological processing of the given component: to begin with gear blank design until the final product. The best option seems to be the die forging on forging press in three steps. From an economical point of view, the die forging realized according to the designed technological processing appears to be the best solution.

Bulk forming technology of carrier pin
Večeřa, Jiří ; Samek, Radko (referee) ; Forejt, Milan (advisor)
This thesis deals with a proposal of a technology for manufacturing a carrier pin made of corrosion resistant chrome steel 17 021.3. Having studied the information about cold bulk-metal forming in the available literature, I have suggested two variants of manufacturing processes. The suggested manufacturing variants consist of four forming operations which combine upsetting and extrusion. As far as the chosen variant is concerned, there have been made technological and strength calculations for the individual operations. As regards the designed technology, I have opted for the automatic multistation forming machine TPZK 25, produced by the company ŠMERAL Brno.

Bulk forming technology of connecting pin
Trnka, Filip ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project elaborated in frame of engineering studies branch M-STG proposes a technology of connecting pin – structural steel 11 320 5R. The technological calculations were performed and the production procedure was devised on the basic on the literary study of cold bulk forming with concentration on the extrusion and upsetting. Forming machine was design HATEBUR BKA-3 with a nominal power 1800 kN. The component is made in four forming operations. Extruder will be made from tool steel 19 830, extrusion die from tool steel 19 830 and clamp ring from tool steel 19 740.

Forging production of Holder of steering pivot
Moudrý, Michal ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
MOUDRÝ Michal: Forging production of holder of steering pivot The project was elaborated in frame of engineering studies branch 2307. The aim of the project was to propose design of technology production of steering pivot holder using solid forming of steel 12 040.0. Based on literary study on die forging and made calculations forging on a vertical crank press LMZ 1000 with nominal forging force of 10MN was designed (producer ŠMERAL Brno). Lower and upper ejectors are used for ejection of components. Induction furnace type SOP 250/6-A30 P/L/T will be used for heating of the raw material. Trimming will be performed using trimming press LDO 315 A/S with press force of 3,15 MN. Dies are made of instrumental steel 19 663.9, for their clamping die clamping device QLZK 1000/UC will be used. A part of this project is economic evaluation of the production and development of production drawings. Keywords: solid forming, die forging, steel forging, holder

Forging of rotary forgings
Konvalina, Michal ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on manufacturing proposal of the conveyor chain sprocket using die forging from steel C45 (12 050). Based on the literature review of eligible technologies, volume termoforming technolology has been selected here, more accurately closed die forging on a vertical crank forging press with an open flash gutter. Dimensions of forging and die are designed according to appropriate valid standards. Based on calculated tensile force of 10,83 MN will be forging performed on vertical forging press LZK 1600 P/SH. Forging die will be made of low alloy tool steel 1.2713 (19 662) and ejection of forging will be executed by three ejector pins in lower and upper finishing die.

Drop forging of pinion
Gráf, Radomír ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch Manufacturing technology (2303R002) presents a technology design of a forged piece – pinion gear – made by drop forging from 14 220.0 (16MnCr5) material. Drop forging in two operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 120 000 pieces a year, will be produced on the drawing inclinable press LMZ 1000 A/(S) with nominal tensile force 10 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project is implemented technical economic evaluation of the technology design.

Production of weapon conclusion
Diviš, Adam ; Forejt, Milan (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of technology for production of weapon conclusion by die forging. The weapon conclusion will be made of C45 steel in series of 500 000 pieces per year. Before forging, the base semi-finished product will be treated using cross-wedge rolling technology. Thanks to the chosen production process, the forging will be made as four pieces. A simulation of the forging process was made for the created design. Results of a simulation showed that metal did not fill entire hollow. Based on these results was made changes in design and the simulation was performed again. According to the results of the second simulation, the hollow has already been filled with metal. For the forging was chosen the machine LZK 2500P from Šmeral a.s with a nominal force 25MN. In the conclusion there was a technical-economic evaluation of costs for the material required for production of entire series.
