Manufacturing of eye
Skalník, Petr ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project follows up design of technology manufacturing of eye, which will be made by drop forging from low-alloyed steel 13 242. Yearly production is set on 300 000 pieces. Pursuant to of the literary pursuit problem and calculations will be the forging made on a hammer with several hits in the finishing hollow. Regarding to calculations of forging work is elected pneumatic-hydraulic power hammer KHZ – 2A with energy of 20 kJ. Die is made of tool steel 19 663 heat-worked according to drawing documentation. Technical and economical evaluation was aimed on a calculation of production expenses of semi-produced material (3 323 109,40 CZK) and on price of the forging machines for yearly production (930 000 CZK).

Issues of drop forging
Břečka, Marek ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The thesis deals with problems of die forging which is a production method that is mainly used in large-scale production. Design of forgings is based on drawing documentation. It evaluates the usefulness of the component, then the required additions are specified and the machine is selected. At present hammers presses and horizontal forging machines are used. Hammers work with hit energy. The movement of the tool ends with an anvil. The component is mostly made for several strokes. Hammers are appropriate for the production of shaped and height-versatile and rugged forgings with ribs and protrusions. Press is a machine that works with pressure. The speed of the ram is relatively small, the effect on the material is quiet and without impact. The biggest application is for die forgings which needs a great force to form. They are used primarily for the production of low and less rigid components. Horizontal forging machines are essentially double-acting presses designed for making forgings of various shapes made of rod material.

Forging gear
Šíma, Vojtěch ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated in a frame of Bachelor‘s studies branch B-STG presents a technology design of a forged piece – gear wheel by drop forging. The wheel is made form 12 050.0 material and is a part of an agriculture machine. Considering the series of 45 000 pieces per a year and the precision of production, the drop forging for three operations was selected for production. The wheel will be produced on the crank drawing inclinable press LKZ 1600 P from Šmeral Brno, a.s. producer with nominal tensile force 16 MN. Swages are made of alloyed instrumental steel 19 552.8. At the end of the project technical economic evaluation of production and comparison of the forging technology and machining technology was implemented.

Drop forging of gear wheel
Bednařík, Petr ; Lidmila, Zdeněk (referee) ; Štroner, Marek (advisor)
The project elaborated design of technology production of gear wheel from circular blanks of steel 12 050. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process. Dies proposal will be based on relevant standards, materials die steel will be 19 552. Given the complexity of the shape and dimensions of the gear will be used in three operations. Based on the calculated forging force was chosen vertical forging sheet LMZ 1600 A/S with a nominal power of 16 MN. Due to the use of the press die is provided with an ejector.

Sobotka, Radek ; Pavlík, Jan (referee) ; Omes, Jiří (advisor)
The subject of this term project is the design of cast multiple-part frame of screw press with direct drive with stated parameters for heavypressing. The first part consists of a research in the field of screw presses focused on the construction of the frame and current manufacturers of the screw presses. The second part is aimed at the design of the frame according to specified parameters. The thesis includes press layout drawing, frame assembly drawing, selected detail drawings and 3D model of the frame.

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

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.
