Production of support by forming
Caha, Tomáš ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
This project developed within the bachelor degree in B-STG present proposal forging technology - parts from bar of circular cross-section of cold rolled 14 220. Based on the literature study problems of die forging and calculation was designed die forging with bottom ejector, designed for easy removal of the forging from die cavity. Die is circular cross section and is clamped with a dovetail groove in vertical forging press LZK 1600 (manufacturer ŠMERAL Brno), with a nominal forging force of 16MN. The lower and upper half of the die is made of steel 19 662, heat threated for the purposes forging.

Produstion of shifting carrier by solid forming
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.

Production of holder by solid forming
Nejedlý, Petr ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of holder by solid forming of steel 12 020.0. Pursuant to of the literary pursuit a problem of die forging and calculation was designed forging on a vertical cranked press LMZ 1600 and with nominal forging force 16MN (producer ŠMERAL Brno). The lower ejector is using for extrusion component.Heating billet is accomplished by using induction furnance type SOP 400kW.For trimming is used trimmning press LKOA 200 with force 2 MN. For holding of dies is used holder QLZK 1600/UC, dies are made of instrumental steel 19 552.9. A part of this project is economic estimation of production and produce of manufacturing drawings.

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.
