Drop forging of gear wheel
Bednařík, Petr ; Lidmila, Zdeněk (referee) ; Štroner, Marek (advisor)
The project elaborated design of technology production of gear wheel from circular blanks of steel 12 050. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process. Dies proposal will be based on relevant standards, materials die steel will be 19 552. Given the complexity of the shape and dimensions of the gear will be used in three operations. Based on the calculated forging force was chosen vertical forging sheet LMZ 1600 A/S with a nominal power of 16 MN. Due to the use of the press die is provided with an ejector.

Manufacturing of pin with flange
Černá, Věra ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project elaborated within the Bachelor study of the branch Manufacturing technology presents a technology proposal of a forged piece - pin with a flange -madeby drop forging from material 15 142. The forged piece will be carried out by several hits in the finishing die. Regarding to the seriality, 800 000 pieces per year, and calculations of necessery strength for the last hit, the forged piece will be made on a counterblow hammer KHZ-2 with energy of 20 kJ. Forging dies are made of tool steel 19552and heat treated according to the drawing docummentation.

Forging production of Holder of steering pivot
Moudrý, Michal ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
MOUDRÝ Michal: Forging production of holder of steering pivot The project was elaborated in frame of engineering studies branch 2307. The aim of the project was to propose design of technology production of steering pivot holder using solid forming of steel 12 040.0. Based on literary study on die forging and made calculations forging on a vertical crank press LMZ 1000 with nominal forging force of 10MN was designed (producer ŠMERAL Brno). Lower and upper ejectors are used for ejection of components. Induction furnace type SOP 250/6-A30 P/L/T will be used for heating of the raw material. Trimming will be performed using trimming press LDO 315 A/S with press force of 3,15 MN. Dies are made of instrumental steel 19 663.9, for their clamping die clamping device QLZK 1000/UC will be used. A part of this project is economic evaluation of the production and development of production drawings. Keywords: solid forming, die forging, steel forging, holder

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 support by solid forming
Pfeifer, František ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
PFEIFER František: Production of support by solid forming. A Graduation Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, FSI VUT Brno, Department of Machining, May 2009, Pages No. 94, Pictures No. 37, Tables No. 3, Appendixes No. 13. The Graduation Thesis, elaborated in the framework of engineering studies, presents the production technology of support component from steel ČSN 12 010. A material is a rod of the 130 – 251 ČSN 42 5510. A yearly production is 95 000 pieces. Based on the studies of possible production technologies was proposed the technology of production by the vertical forging press LMZ 6500B (Šmeral Brno a. s.) with a nominal forming power of 65 MN, flash and pellicle trimming on a trimming press with a nominal power of 8 MN. For this option, the required technological calculations, the design of the die, the specification of production machines and a simulation forming process which is made in the software QFORM have been carried out.

TICHÝ Pavel: Production of a holder body by solid forming. A Graduation Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, FSI VUT Brno, Department of Machining, May 2009, Pages No. 80, Appendixes No. 9. The Graduation Thesis, elaborated in the framework of engineering studies, presents the technology of a body holder production carried out by solid forming. The material of the forged piece is steel Ck55 (12 060), the semi-finished product is of the 65 and its length is 12m. A yearly production is 122 000 pieces. Based on the studies of possible production technologies, the technology of production by die forging has been chosen, while a drop forging technology on a hammer HO630 and product-trim on a trimming press S160 have been used. For this option, the required technological calculations, the design of the die, the specification of production machines, which are necessary for forging process realization, have been carried out. An inspection of the propose forging by a private forge and a change in the geometry of the die have been carried out. A part of the study is a simulation forming process which is made in the software QFORM.

Analysis of forging disagreement
Novotný, Karel ; Hoza, Jiří (referee) ; Fiala, Alois (advisor)
This diploma thesis deals with the generation of the different drope stampings in industrial process in MBNS Kovárna Company. The main purpose of this thesis is analysis of the industrial process and finding the main factors influences on the process. It especially deals with forgings of the shafts and also flanges with the similar quality of material 42CrMo4. Reasons of the disagreements are focused on surface insensibilities of the forging - crack. First theoretic part introduces company, meaning of the quality of material and describes tools used for finding reasons of the generation of disagreements. In the second practical part is described the whole industrial process and determination of the reasons of disagreements. In concluding part the results are analyzed and some correctional recommendations are suggested.
