Buffer box of a wagon
Řezáč, Patrik ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The subject of this work is the proposal of a technological process to create a train car bumper using volume thermoforming. The S235JR (11375) steel has been chosen as the main material. The work contains technological calculations, blueprint documentation of the mold, of the tool and a proposal of the set of machines for the production line. The capacity of such production line has been calculated to be 12460 pieces per year. Economical-technological evaluation of the production is also included.

Productin of injector holder
Štys, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
This paper presents a design of the production process for the clamping nut by cold extrusion. The nut, which is made of material ČSN 12 050, is used to clamp the injection nozzle to the injection system. Subsequently different variants of production were processed, from which the variant B was chosen. For slug a rod with diameter size of 24 mm with toleration f9 made by the company Ferona a. s was chosen. Calculations of process parameters were made for this variant. Based on the parameters the automatic forming machine TPD 630 with nominal force of 6 000 kN was chosen. For the selected machine, operational tools were designed for each forming operation, whose geometry is shown in the drawing documentation. Based on the technical and economical evaluation, the final price of the formed part was set at CZK 18,48.

Bulk forming technology of pin connector
Kříbala, Milan ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The Bachelor’s thesis deals with the production of the coupling pin cold bulk forming with focus heading and extrusion. The part will be made of structural steel 11 320 5R. The size of the production is about 700 000 piece per year. The two processes was chosen for four forming operation. From the technological calculations were set forming by force 465 kN needed to select a suitable forming machine. Automatic machine TPM 8-A was elected due to force 1000 kN. The drawing documentation is part of the work. Extrusion tools are made of tool steel 19 830. One piece costs 0,6 Czech crowns – this calculation was in the technical-economic assessment.

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.

Production of shaft
Jančík, Petr ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis is classified under the field of Engineering Technology and proposes a process for the production of a shaft made of steel 12 050 by combined extrusion. The material in question can be used, for example, for parts of mining machines, larger gears, pins or screws. In accordance with the acquired findings on the issue of volume forming, the production of the component was designed for two forming operations. A block with a diameter of 55 mm and a length of 146 mm was chosen as a semi-finished product. The production was designed on a Schuler automatic machine, which is a part of the company Metaldyne Oslavany, with a nominal force of 2 000 tons and a height of 7 meters in a series of 100 000 pieces per year.

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.
