Drop forging of hub
Leidorf, Michal ; Kopřiva, Miloslav (referee) ; Štroner, Marek (advisor)
The Baccalaureate thesis deals with literary studies of forging. There is also processed the proposal of technology of ordered steel cog-wheel num.: BP-3-2009- 001. With regard to supposed large series of 150 000 pieces per a year, the technology of stamping on three operations at the vertical forging press LZK 4000B is chosen, the producer Šmeral brno a. s. All calculations were accomplished during the processing of the technological procedure, the following design documentation and technical-economical estimation are connected with the preceding calculations..

Forging oblong forgings
Chudý, Jan ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
This bachelor´s thesis is focused on design of technological production procedure of front wheel-drive arm of agricultural machine. Material for construction of this part is unalloyed steel 12 060. Part of this thesis is literall study focused on forging. On basis of this study is designed required forged piece, which will be processed by swaging on hammer KHZ 4A. After swaging is needed removal of excess material in form of burr and stencil with trim pressing machine LKOA 200. Swadge is made of alloyed tool steel 19 662. Part of thesis is mechanical drawing documentation and technical-economical assessment.

Production of forging piece "Spanner"
Vávra, Jan ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Projects developed within the bachelor's degree in Mechanical Engineering, presented a proposal technology forged wrench - the hot-rolled steel bars 11 523.0. The thesis also compares the past with conventional methods of production and considering the new technological process of manufacturing. Based on the literature studies about fitting and calculations, was chosen to die forging hammer KHZ 2 A (producer ŠMERAL Brno, plant Hronov), with nominal energy of 20 kJ working pressure of 16 MPa and 30 kW electric power.

Drop forging of pinion
Kameník, Tomáš ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
KAMENÍK Tomáš: Drop forging of pinion The project has been elaborated within the framework of studies of the subject B 2307 and it presents the lay-out of the technology of the forging – the pinion which is made as the drop forging from the material 14 220. The rougher and the finishing forging die were suggested on the bases of the literature study of the drop forging. In consideration of the big series /100 000 pieces/ and the calculated forging power /25MN/ the component will be made on the vertical forging press LZK 2500P/SH (the manufacturer ŠMERAL Brno a.s.). At the end of the thesis there are performed calculations of the technical and economic evaluation.

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.

Precision forging
Bužga, Petr ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with methods, procedures and possibilities of precision forging. After the initial analysis methods of die forging with collar also comprises an overview, analysis and description of methods of precision forging, including a technological evaluation in view of technical possibilities, investment requirements and expected benefits. The main emphasis is laid on the technological conditions, procedure, on the construction of the dies and forging devices.

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.
