Forging of a hinge eyebolt
Puklický, Vladimír ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
Bachelor thesis developed in the bachelor degree addresses the production process eyebolt combination of the two technologies volume thermofotming. Forging the forging and die forging slug for making the final shape of the part. Eyebolt will be produced in a series of 5,000 units / year of structural steel ČSN 11 375.1 with a carbon content of 0.2 % C. The material is supplied in the form of round bars with a diameter of 135 mm and a length of 6000 mm . From this it will be cut smaller pieces using a 172 mm long industrial scissors ScKU 800 Based on the literature study and fitting the calculations was chosen for forging hammer KHZ 4 A from Šmeral Brno as and drop forging hammer with the designation L 9 mg in 2040 by a French company Bché . Semi-finished product is heated in a gas chamber furnace RKG 08.9.03-12 with an output of 600 kW. Forging the trimming on the trim press LKOA 200th Dies are made of tool steel DIN 19 663.

Drop forging of pinion
Cvrček, Jan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The final project has been elaborated in a frame of Bachelor’s studies branch Manufacturing technology assesses design of production pinion by method of die forging. The pinion is manufactured from alloyed structural steel 14 220 (1.7131). Size of production is set on 100 000 pieces per year. The pinion will be forged on the vertical forging press LMZ 1000 A with forming force 10 MN. The forging is formed in two operations. Forming tool is manufactured from alloyed instrumental steel 19 552 (1.2343). In the last chapter of the project is described the price comparison and costs for manufacture of die forging and machining.

Drop forging of gear wheel
Bezděk, Pavel ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
Objective of this bachelor thesis is design of forging of gear manufactured by die forging. Material of gear is steel 12. According to number of forgings per year, forging of gear will be done on vertical forging press LMZ 2500 with nominal forming power of 25 MN. Dies are made of middle doped steel 19 552. In conclusion, costs of producing of gear forging with selected manufacturing technology are evaluated.

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.

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.
