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.

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.

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.

Manufacturing of a Pin
Glatter, Jiří ; Forejt, Milan (referee) ; Řiháček, Jan (advisor)
The work presents a proposal for the technology of production of a pin of gear assambly.The pin is used to position the wheel in a tapered roller bearing. Pin is made of 11 320.3 steel (11 320 5R), which is suitable for cold forming. Based on the study of cold forming and calculations, the methods of upsetting and extrusion were chosen. Most often, several methods are used for fabrication, which are mediated by a combined tool. It can also be made by any of the machining methods.

Production of coupling pin
Pátek, Martin ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
In this thesis there was designed a technological procedure of production of the coupling pin. As a material was selected low alloyed, construction steel 27MnCrB7-2. From the analysis of susitable methods was selected bulk forming technology, on which is focused theoretical and practical part of the thesis. There was designed the production in three forming operations, which were also devided to two steps because of enervation of plastic properties. Before both steps, there was done heat and surface treatment. For all operations there was designed a special tool, only the clamping parts are universal. The first step will be implemented on hydraulic press Schüler p200 with nominal force 20 000 kN and the second one on mechanical press Krupp p63 with nominal force 6 300 kN. For extruding dies and punches was selected material 19 436 with subsequent heat treatment by the technical documentation. Overall costs of the whole batch are 17 733 870 Kč. With 30% margin these costs are deleted by the 43 945 finished pieces and after this it is only profitable.
