Manufacturing of pin with flange
Procházka, Pavel ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The bachelor thesis is focused on the design of the towing hitch, which is used in the tractor. The component will be the production of a die forging technology made of low-alloy steel 13 242. The material is supplied as hot-rolled bars with a diameter of 60 mm and a length of 6 000 mm. The size of the production series has been set at 25,000 pieces per year. Due to the issue and the size of the forging, the component will be made on a power hammer. The machine Šmeral KHZ 8A, appears to be a suitable machine as the forging work was calculated at 89 kJ. The technical - economic evaluation takes into account material costs, which amount to 1,364,271 CZK. The die is made of tool steel 19 663, its purchase price is 73 000 CZK.

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.

Gear production design
Rusková, Marie ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of a gear, which is located on the rear half-axle of the tractor. Due to the high torque transmission, it will be made of 12 061 steel. After assessing the various production technologies, the forging on the vertical crank press were chosen as the most optimal. Forging was designed according to the standard ČSN 42 9030. The semi-finished product is going to be a rod with a diameter of 125 mm, which will be divided by cutting to a length of 219 mm. Forging will take place in three operations. Based on the highest calculated required force, which came out to 63.16 MN, the LZK 6500 machine was chosen. An LDO 315 A/S trimming press will be used to remove the protrusion and membrane.

Production of bottom body by solid forming
Kaděra, Jakub ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
This diploma thesis, which has been elaborated within Master's study programme Manufacturing Technology and Management in Industry (2303T005), submits a production proposal of production of bottom body by solid forming and its economical evaluation containing all the economical essentials needed in order to produce and specify the final price of a forging. This thesis takes in all the necessary calculations and machinery proposals according to the material of dies and to annual capacity of 250 000 pieces of forgings requested. Semi-finished product for the manufacture of forging is cut size of bars of circular cross-section of steel 14 220 ČSN 42 5510.

Producing of artillery shell
Moravec, Zdeněk ; Forejt, Milan (referee) ; Lidmila, Zdeněk (advisor)
The diploma thesis deals with the technology of production of the body of an artillery shell caliber 155 mm from C60 steel. The part is manufactured in series of 100,000 pieces. Based on a literature study and materials, a technological procedure of drop forging was designed, taking into account the specific shape of the forging. The volume of the starting blank and the forming force were determined. A suitable forming machine was selected based on the magnitude of the forming force. The design of tools for punching operations and reduction diameters of sets of rollers for forging stretching was also performed. In the technical and economic evaluation, the material costs for the production of the entire series were quantified.

Production sprocket
Diviš, Adam ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated design of technology production of the sprocket using die forging from steel C45. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process for three operations. Dimensions of forging and tool are designed according to appropriate standards. Forging will be done on forging press LZK 1000 P/SH, with nominal tensile force 10 MN. Dies will be made from instrumental steel 19 662 heat-worked according to drawing documentation.

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 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.

Design of forging line
Pazour, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The thesis is focused on designing of automated workplace meant for production of gear made of steel 11 523 with yearly production of 500 000 pieces. After considering all of the input data, it was decided to use die forging. A forging with flash was designed from the original shape of the gear. Forging force was calculated, and its value is 25,08 MN. Press LZK 4000 B was chosen for such force and is part of a forging line. Another machinery are induction heater KSO 1200/1,2-C40, trimming press LDO 500 A/S and lubricant mixing and supply system DAG 183 BMS. The choice of presses was justified by calculated forces. Industrial robots IRB 6660 and conveyors are providing material handling. Thesis contains two possible layouts, one with a square area of 400 m2 and another with a rectangular area of 420 m2. At the end was calculated production time of a piece. If robot were moving at 1 ms-1, production of one piece would take 25,9 s and for 2 ms-1 it would take 18,2 s.
