Bulk forming technology of connecting pin
Trnka, Filip ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project elaborated in frame of engineering studies branch M-STG proposes a technology of connecting pin – structural steel 11 320 5R. The technological calculations were performed and the production procedure was devised on the basic on the literary study of cold bulk forming with concentration on the extrusion and upsetting. Forming machine was design HATEBUR BKA-3 with a nominal power 1800 kN. The component is made in four forming operations. Extruder will be made from tool steel 19 830, extrusion die from tool steel 19 830 and clamp ring from tool steel 19 740.

Bulk forming technology of carrier pin
Večeřa, Jiří ; Samek, Radko (referee) ; Forejt, Milan (advisor)
This thesis deals with a proposal of a technology for manufacturing a carrier pin made of corrosion resistant chrome steel 17 021.3. Having studied the information about cold bulk-metal forming in the available literature, I have suggested two variants of manufacturing processes. The suggested manufacturing variants consist of four forming operations which combine upsetting and extrusion. As far as the chosen variant is concerned, there have been made technological and strength calculations for the individual operations. As regards the designed technology, I have opted for the automatic multistation forming machine TPZK 25, produced by the company ŠMERAL Brno.

Production of cold forging parts
Jedovnický, Jan ; Samek, Radko (referee) ; Špaček, Jindřich (advisor)
A project developed during a magister´s study of a program M-STM Mechanical engineering and industrial management brings in a proposal of a technology of cold forging part out of 12 040 steel. The forging on a multi-stage processual automatic machine TPZK 25 with nominal forming power 5000 kN was projected based on consultations, study of literary resources a calculations.

Bulk forming technology of cases
Covrighin, Sergiu ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
Bc. COVRIGHIN Sergiu. Bulk forming technology of cases. Diploma thesis in fifth class of master studies, academic year 2009/2010, study group 5M/68, FME UT in Brno, Institute of Manufacturing Technology, Department of Metal Forming, May 2010, pages 46 , 18 fig., 7 tab., 4 annexes. In diploma thesis is introduced a technological proposal regarding production of cases by bulk forming from cemented steel 14 220.3. Despite the estimated number of parts which is 70000 a year, quality and product accuracy, 2 options of technological procedures concerning cold bulk forming wth combination of backward and forward extrusion are being considered. For chosen option are elaborated technological calculations. As for the suggested technology, crank press, force 8000 kN and made by company KRUPP was chosen. Material for extruder is steel 19 569 and material for extrusion die is steel 19 655.

Manufacturing possibilities of sparking plug body
Strnad, Miroslav ; Kopřiva, Miloslav (referee) ; Podaný, Kamil (advisor)
Difficulties of manufacturing sparking plug body are analyzed in this thesis, which aims to select the most appropriate option. Body is circular section of steel 1.1191 (12 050), with a hole in the middle and upper part of this body is ended with hexagonal shape. The series is estimated at 1 000 000 units per year. For the production of sparking plug body are selected options from the machining and forming technologies. Specifically, turning and milling, casting, forging, a method using superplastic material and cold extrusion. Selected technologies will be reviewed based on cost to produce one piece, time requirements of manufacture of the unit, material usability and overall feasibility. According to these parameters forming is chosen as the best option.

Forming technology production of window hanger.
Štejnar, Radek ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
An objective of the bachelor’s thesis is the solution of forming technology production of window hanger by means of backward extrusion and elaboration of study concerning cold bulk forming. Required component is made of material ČSN 41 1320 5R and rounded chock with dimension of 14,6h9 - 25,3 mm is selected as semifinished product for production. Generally 2 alternatives of technology process were assessed whereas technological and strength calculations are executed utilizing computing support of TVÁŘENÍ and OPTIM97 software. Component is produced within 4 operations including cutting of wire. Multi-stage cold forming press TPZK 25 made by ŠMERAL a.s. Brno producer was chosen for designed technology. Production tools are made of high speed tool steel 19830.
