Production of the piston rod eye
Vahala, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project deal with technology design of production of the piston rod eye from steel 11 523 in the amount of 30 000 pieces. From various possibilities of technology was chosen as the most optimal method the technology die forging. Pursuant to the study of literature and calculations there will be made the forging as a double-edged in single-cavity die on hammer witch several hits in finishing hollow. According to the calculated energy there was selected pneumatic-hydraulic hammer KHZ-4A witch stated energy of 40kJ. The tool was made of steel 19 552, heat-treated according to the drawing documentation. The technical and economical evaluation was focused on the total material cost of the semi-finished material and the cost of manufacturing forging die, which is 1 229 507 CZK in total.

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.

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).

Drop forging of pinion
Mikeš, Filip ; Žák, Ladislav ; Štroner, Marek
The project deals with the design of the requested part, with technology of volume thermoforming – drop forging. The literature study was written according to this technology and the design of pinions manufacture from steel 14 220 was made. On the basis of the calculated forging force, the molding machine LZK1000P/SH, from the company Šmeral Brno, a.s., and other necessary machines were chosen to manufacture the forged piece. According to chosen machines and calculated parameters, the manufacturing process, the drawing documentation and the technical – economic evaluation were compiled.

Method development of forged piece in conditions of modern forge
Vraštiak, Michal ; Psík, Eduard (referee) ; Podaný, Kamil (advisor)
Taking into account modern technology solutions has been selected die forging of the wheel hub of automobile steel 14220 (DIN 16MnCr5) about the serial 50000 pcs. Based on the literature study and practical experience has been solved forging process, including technological calculations, engineering drawings and results of simulations of the forging process performed by the Qform software tool. A tool was designed to be made of 19552 grade alloy tool steel. The forged piece is to be forged on an LZK 1000 crank press with the nominal forming force of 10 MN manufactured by Šmeral Brno. The stock is divided with shears from bar 45 mm 6 m long to bar 89.5 mm long.

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.

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 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.
