Produstion of internal wheel, by solid forming
Šimon, Miroslav ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The point of this work is bookish concept of the best technology of processing named component by solid forming. This work includes study, which is the clue to solutions. Another important topic is the global technological plan of component production from gear blank to product. It seems the best choice is die forging on forging press at three steps. Economically, die forging made by described method is the best.

Forming technology production of window hanger.
Štejnar, Radek ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
An objective of the bachelor’s thesis is the solution of forming technology production of window hanger by means of backward extrusion and elaboration of study concerning cold bulk forming. Required component is made of material ČSN 41 1320 5R and rounded chock with dimension of 14,6h9 - 25,3 mm is selected as semifinished product for production. Generally 2 alternatives of technology process were assessed whereas technological and strength calculations are executed utilizing computing support of TVÁŘENÍ and OPTIM97 software. Component is produced within 4 operations including cutting of wire. Multi-stage cold forming press TPZK 25 made by ŠMERAL a.s. Brno producer was chosen for designed technology. Production tools are made of high speed tool steel 19830.

Production of the screw
Starý, Petr ; Podaný, Kamil (referee) ; Císařová, Michaela (advisor)
The bachelor´s degree project deals with the production of rotating component using cold forming technology. There are described basic principles of technology, used material, tools and machines and the area of usage. Production of the screw is based on the literary studies and technical calculations. The suggested manufacturing variant consists of five steps and containing cutting, extrusion and upsetting. As raw material was chosen a wire with diameter of 12,5 mm and length of 38,6 mm made of steel 12040. For chosen variant was made technological and strength calculations for the individual operations.

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.

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.

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

Production of holder by solid forming
Nejedlý, Petr ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of holder by solid forming of steel 12 020.0. Pursuant to of the literary pursuit a problem of die forging and calculation was designed forging on a vertical cranked press LMZ 1600 and with nominal forging force 16MN (producer ŠMERAL Brno). The lower ejector is using for extrusion component.Heating billet is accomplished by using induction furnance type SOP 400kW.For trimming is used trimmning press LKOA 200 with force 2 MN. For holding of dies is used holder QLZK 1600/UC, dies are made of instrumental steel 19 552.9. A part of this project is economic estimation of production and produce of manufacturing drawings.

Production of part Tube by solid forming
Grufík, Lubomír ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Propose of this thesis is designing production technology of reducing part of tube. The production of requested part is designed on the base of calculations and simulation in one operation. This operation contains widening and squeezing. There is designed on the base of calculations a tool fixed in hydraulic press ZHW 40 for the production. To prepare a semi-product is used cutting by slitting saw.
