Production of pinion
Vališ, Ondřej ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor thesis deals with literature study of cold forming technology. Further the thesis submits a proposal of the production technology of pinion into the gearbox of passenger vehicles made from alloy steel according to ČSN 16 326. Thanks to knowledges aquired by literary study of bulk forming issue was suggested a direct extrusion technology with consequential cold upsetting. The component part will be produced in two production processes and series of fifty thousand pieces per year. These manufacturing processes will be used on forming machine called Schuler with nominal force of two thousand tons which is part of Metaldyne Oslavany company involved in automative industry.

Production of high pressure hydraulic filter housing
Podloucký, Lukáš ; Lidmila, Zdeněk (referee) ; Císařová, Michaela (advisor)
The Bachelor’s thesis is focused on solving the problem of production of high-pressure hydraulic filter by cold extrusion technology. The initial semi-finished product is a C15R steel cap with a diameter of 104 mm and a height of 57.9 mm. The production series assumes a quantity of 30,000 pieces per year. The technologicality of the product evaluation was based on technical literature knowledge and professional experience. The technological process was chosen subsequently. This process counts with the extrusion in two operations with mid-operational recrystallization annealing and with the use of surface treatment by phosphating and soaping. An Eitel 1 250 press with a nominal forming force of 12 500 kN is designed for the production. The design of the forming tools takes into consideration the shape of the extrusion, technological principles and mathematically verified safety. The material of the die and punch is high-speed tool steel 19 830. The material of the ejector it is high-alloy tool steel 19 437. The technological process and force calculations are verified by simulation of the forming process created in the Simufact Forming program.

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.

Design and realization of extrusion head and connecting members for extrusion of circular plastic profiles
Novák, Jakub ; Veselý, Oldřich (referee) ; Koutný, Daniel (advisor)
In this work is developed a proposal for extrusion head for extruding plastic wires of small diameter. There is a new conceptual design of cooling, which allows shape extruded products already in the extrusion head and thereby eliminates the need for large cooling tanks. To determine the optimal design is used software named Virtual Extrusion Laboratory, which is used in practice for the simulation of the extrusion process. Then it is experimentally determined behavior of plastic material, when the temperature of the melt in the extrusion head is reduced.

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.
