Stříbrný, Jan ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
The Project elaborated in frame of bachelor's studies branch 2303 and it presents technology design and forging production - part of aluminum alloy EN AW 6082 T6. Drop forging in one operation was suggested on the basis of specialized studies on the subject of drop forging and calculations. Regarding urgent need use of ejector pins and other aspects, he was elected vertical forging press LZK 1000 P / SH (producer ŠMERAL Brno), with a nominal force 10 MN. Swages are made of alloy instrumental steel, 19 552.8, heat-worked according to drawing-documentation.

Drop forging of hub
Vostřel, Jan ; Novotný, Karel (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch B 2307 presents a technology design of a forged piece – hub – a part of a gear box made by drop forging from 14 231.0 material. Drop forging in three operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 40 000 pieces a year, preciseness and automatization of production of the part, will be produced on the crank drawing inclinable press LMZ 2500 (producer Šmeral Brno, a.s.) with nominal tensile force 25 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project technical economic evaluation of the technology design is implemented.

Die forging
Stračánek, Rostislav ; Šlais, Miroslav (referee) ; Lidmila, Zdeněk (advisor)
This diploma thesis is based on proposal of manufacturing technology forging of connection rod by die forging. The connection rod is made of 12 050 steel and it is part of crank mechanism in combustion engine. Production series was specified to 120 000 pcs. for year. Into technology procedure was implemented method of cross wedge rolling before die forging. The material for transverse cross wedge rolling was chosen 19 554 steel. Process of die forging was selected three operation in vertical forging press LZK 4000 with pressure force 40 MN made by company Šmeral Brno a.s. For die material was chosen 19 552 steel. And finally was carried out technical and economical evaluation of the forging production.

Production of holder by solid forming
Špaček, Antonín ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
The diploma thesis deals with suggestion of low alloy 14220.0, produced by solid forming. This suggestion is based on the size of series that contain 100 000 pieces a year. The essay contains knowledge refering to drop forging technology and comparison with existing technologies. Two suitable variants of production were assessed, these variants are drop forging with hammers and vertical forging press. Both theories were theoretically analised in order to describe given technology. The analysis also contains calculation and suitable machine choice. Drop filling on vertical forging presses was chosen because of forging type. Furthemore forging proposition was treated including production technique. The chosen variant contains calculation, suggestion of a die, machine that was used and suggestion of flash trimming. For suggested technology was chosen vertical press LZK 3150 B. Its producer is Šmeral a.s. Brno. This project also contains technical drawings of the given component, forge, dies and phase of forging.

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 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.

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).

Production of carrier by forming
Pluskal, Martin ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of the engineering studies branch N2326 presenting the design of manufacturing technology of forging carrier of steel 14 220. Pursuant to the literary pursuit a problem of solid hot forming was proposed to product by drop forging with flash on 3 forging operations. All the operations are realized on the vertical crank forging press LZK 4000 B produced by ŠMERAL BRNO a.s. with nominal forming force 40 NM. Heating material on the forging temperature 1100 °C will proceed in the electric induction furnace produced by ROBOTERM s.r.o. type KSO 800kW, the flash trimming on the trimming press LDO 315 A/S with nominal forming force 3,15 MN. Dies are made from tool steel 19 552.9 and strapped in die holder QLZK 4000/UC. A part of the project is technical economic analysis evaluation and elaboration of production scheme. Expected annual volume is 100 000 pieces.
