Issues of hammer die forging
Žižka, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This bachelor thesis deals with issues of hammer die forging which is technology that is mainly used for the production of shaped and height-versatile and rugged forgings with ribs and protrusions. Forgings are made by several blows of the tools which are called dies. Design of forgings is based on drawing documentation. For successful production of the component it is important to choose right forging temperature, parting line, required additions and tolerances. Hammers are machines which work with hit energy, they use kinetic energy for forming the material. Their characteristic features are good climbing of the material and filling deeper chambers in direction of the hit. Several types of hammers are used, for example fall hammer or double acting hammer and more.

Progress in technology of mold milling with coated profile tools
Doležel, Ondřej ; Bumbálek, Bohumil (referee) ; Píška, Miroslav (advisor)
This diploma thesis is involved in possible development of different types of milling molds coated with modern plows. The first part is devoted to an analysis of contemporary trends in forms production technology. The analysis includes the different types of machines and tools for making various kinds of molds and dies. Another part deals with design of dies for sheet metal shears. The thesis continues by design of the production procedure after heat treatment and finishing die by miling. For milling of die are designed miling tools, the NC program and the possible development of manufacturing the die using a new machining center and the possibility of production optimization. The penultimate point of the thesis is technical and economical evaluation of the direction of development and comparison of positives and negatoves of each method. At the final evaluation is all summed up.

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).

Design of wheel hub production
Šidlák, Filip ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design the technology production of wheel hub for the automotive industry made of C45 steel. After the evaluation of suitable technologies, a die forging on a mechanical press was selected. On the basis of technology analysis, the component shape was modified, all allowances and dimensional tolerances were set. According to calculated forming force, the crank press LZK 3150B with nominal force 31, 5 MN from the manufacturer Šmeral Brno, a. s., was chosen. Manufacturing is divided into two operations, pre-forging and after that final forging. Design of dies is based on the ČSN 22 8306 standard and they are made of tool steel of grade 19 552 with the subsequent heat treatment. The dies have upper and lower ejector for easier removal of the forged piece.

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.

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.

Production of support by solid forming
Pfeifer, František ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
PFEIFER František: Production of support by solid forming. A Graduation Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, FSI VUT Brno, Department of Machining, May 2009, Pages No. 94, Pictures No. 37, Tables No. 3, Appendixes No. 13. The Graduation Thesis, elaborated in the framework of engineering studies, presents the production technology of support component from steel ČSN 12 010. A material is a rod of the 130 – 251 ČSN 42 5510. A yearly production is 95 000 pieces. Based on the studies of possible production technologies was proposed the technology of production by the vertical forging press LMZ 6500B (Šmeral Brno a. s.) with a nominal forming power of 65 MN, flash and pellicle trimming on a trimming press with a nominal power of 8 MN. For this option, the required technological calculations, the design of the die, the specification of production machines and a simulation forming process which is made in the software QFORM have been carried out.

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.
